  2. 2. Mathew Beane @aepod Director of Systems Engineering - Robofirm Zend Z-Team Volunteer – Magento Division Family member – 3 Kids and a Wife Magento Certified Developer Scaling Magento – Mathew Beane - php[world] 20152
  3. 3. Scaling Magento – Mathew Beane - php[world] 2015 Magento: What is it? • Open-source e-commerce platform • PHP based application • Core utilizes Zend Framework 1 • Very flexible, built to modify • Extremely scalable, supports huge stores • Market leader and still growing • Magento 2 is right around the corner • 2.0.0-rc2 is out now • http://magento.com/developers/magento2
  4. 4. Scaling Magento – Mathew Beane - php[world] 2015 Cluster Configuration Overview https://github.com/aepod/magento-digitalocean-sandbox • Uses Puppet to build out cluster • To setup the initial test checkout readme in project • Initial release standard (n)webnodes + single db config • Monolith server has Web, PHP, DB, Redis all-in-one • We will come back to this later
  5. 5. Scaling Magento – Mathew Beane - php[world] 2015 Using the Magento Vagrant Puppet Sandbox 1) Install Vagrant 2) Install Digital Ocean provider 3) Grab the project source from github git clone https://github.com/aepod/Magento-Vagrant- Puppet-Sandbox.git 4) Add your Token to Vagrantfile 5) Ensure you have a ssh key 6) Stand up some boxes vagrant up puppet * Add puppet IP from output to Vagrantfile vagrant up monolith Vagrant https://www.vagrantup.com/ Digital Ocean Provider https://github.com/smdahlen/vagrant-digitalocean Magento Vagrant Puppet Sandbox https://github.com/aepod/magento-digitalocean-sandbox

Scaling Magento - Todays Plan • Introduction • Magento Application: Preparing and Optimizing • Magento Cluster Architecture: Examine Typical Layouts • Magento Digital Ocean Sandbox: Demonstrating Clustering • Magento Performance Toolkit: Measuring Performance Benchmarks • Magento Digital Ocean Sandbox: Guided experiments • Conclusion: Open Q & A
  7. 7. Preparing and Optimizing
  8. 8. Before You Start Clustering Optimized Server Settings Magento application is optimized and clean Development pipeline in place Deployment infrastructure is solid Rigorous testing protocols are in place Pre-Scaling Checklist
  9. 9. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Overview • Optimize sysctl.conf: Increase limits for the servers • Modify Nginx settings: • Setup PHP FPM with TCP properly • Optimize Worker Connections • Tune up caching and other settings • Optimize PHP FPM • Process Manager Optimization • APC / Zend Opcode Cache • Tune up other settings • Optimize Redis • Optimize MySQL The goal is to optimize flow.
  10. 10. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – Linux Kernel • Sysctl is an interface for configuring the Linux Kernel. • The following slides show some examples of the settings you may change in the sysctl.conf. • Remember to backup your configurations. • After changing you run: sysctl –p to update your kernel settings. • Always test after changing values, quantify your results against previous tests. See also: https://access.redhat.com/documentation/en-US/Red_Hat_Directory_Server/8.2/html/Performance_Tuning_Guide/system-tuning.html
  11. 11. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – Linux Kernel # Controls the maximum shared segment size, in bytes (64gb) kernel.shmmax = 68719476736 # Controls the maximum number of shared memory segments, in pages (16gb) kernel.shmall = 4294967296 #controls the number of process identifers that can be created kernel.pid_max = 2097152 # Number of open files handles fs.file-max = 2097152 # Defaults to 65536 – Deals with malloc maps. vm.max_map_count = 262144 You can find a lot more tuning information by looking up the parameters and learning more about them.
  12. 12. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – Linux Kernel net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 net.core.rmem_default = 1048576 net.core.wmem_default = 1048576 net.core.netdev_max_backlog = 65536 net.core.somaxconn = 65536 net.ipv4.tcp_rmem = 4096 1048576 16777216 net.ipv4.tcp_wmem = 4096 1048576 16777216 net.ipv4.tcp_max_syn_backlog = 65536 net.core.somaxconn is the least trivial, and typically set very low causing the following: “apr_socket_recv: Connection reset by peer” and “connect() … failed“. Queuing up packets efficiently, make sure you have enough space in your buffers.
  13. 13. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – Nginx location ~ .php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/html/$fastcgi_script_name; fastcgi_param MAGE_IS_DEVELOPER_MODE 0; fastcgi_param PHP_VALUE error_log=/var/log/php-errors.log; include fastcgi_params; fastcgi_cache off; fastcgi_buffer_size 128k; fastcgi_buffers 256 16k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; fastcgi_read_timeout 900s; }
  14. 14. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – Nginx Battle Hardened Magento Nginx Config: https://gist.github.com/gwillem/cd5ae6845fa33aa0d481 worker considerations: Worker Processes = Total # CPU Cores Worker Connections: ½ of ulimit –n Max Connections = worker processes * worker connections Worker_rlimit_nofile safe value = 2 * Max Connections keepalive_timeout mitigates overage by trading for latency
  15. 15. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – Nginx # Media: images, icons, video, audio, HTC location ~* .(?:jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm|htc)$ { expires 1M; access_log off; add_header Cache-Control "public"; } Set long expires dates on media assets. Bonus: Use a CDN to offset all Media and CSS calls.
  16. 16. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – Nginx curl -X GET -I www.idealphp.com:80/skin/frontend/rwd/default/images/logo.gif HTTP/1.1 200 OK Server: nginx/1.0.15 Date: Tue, 14 Apr 2015 17:56:32 GMT Content-Type: image/gif Content-Length: 2320 Last-Modified: Tue, 14 Apr 2015 00:30:08 GMT X-Robots-Tag: noindex, nofollow, nosnippet, noarchive Accept-Ranges: bytes Cache-Control: max-age=31536000 Cache-control: public Test your headers using curl or other tools
  17. 17. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – PHP-FPM • PHP 5.4 - Minimum • PHP 5.5 – Great, better performance if you have compatibility • PHP 5.6/5.7 - Even Better, although not officially supported • PHP 7 / HHVM - No official support until Magento 2. Magento 1 HHVM: https://gist.github.com/tegansnyder/96d1be1dd65852d3e576 - Lots of work went into this by Tegan Snyder (@tegansnyder) - Thanks to Daniel Sloof (@daniel_sloof) for doing MUCH of the groundwork allowing this to work • Use TCP instead of sockets • Test with Zend OpCache instead of APC • Turn off APC Stat/Zend Revalidate apc.stat = 0 opcache.revalidate_freq=0
  18. 18. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – PHP-FPM Tune Process Manager • pm: ondemand • pm.max_children: about 6-8 per CPU *more later • pm.max_requests: 10000 *php threads should die for garbage collection • listen.backlog: set to 64000 (typically set to -1 or 128) Listen backlog is limited by net.ipv4.tcp_max_syn_backlog *only do after sytsctl.conf optimization
  19. 19. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – PHP-FPM pm.max_children will limit the amount of memory php uses overall • Calculate the memory a thread is using while under load: ps --no-headers -o "rss,cmd" -C php-fpm | awk '{ sum+=$1 } END { printf ("%d%sn", sum/NR/1024,"M") }' • Use the total amount of memory you want php to consume: pm.max_children = Total RAM dedicated to the web server / Max child process size Based on this, you can set your max_children based on memory instead of the CPU metric used earlier. This will allow for more memory consumption in production environment. Be sure to test with higher values, more is not always better.

  20. 20. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – Redis • Redis is the preferred cache for Magento • sysctl ulimit values affect the redis maxclients • Use three separate Redis instances with a single DB in each, on different ports • tcp-backlog can be increased, adjust sysctl somaxconn and tcp_max_syn_backlog • maxmemory can be set very low typically. • Using Sentinel and twemproxy you can horizontally scale • Clustering redis to eliminate all single threaded bottlenecks and single points of failure • Requires orchestration, and Magento application changes • Don’t forget to update Cm_Redis to newest version (Magento lags behind) • At Rackspace or AWS: Use Object Rocket https://objectrocket.com/ for Redis SaaS
  21. 21. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – MySQL • Turn off MySQL Query Caching – This is single threaded and not of use with Magento (* Before MySQL 5.7) • Innodb settings can be tweaked to consume more memory Selected Sample Configuration Settings for a 32GB Dual Hex-Core Server myisam_sort_buffer_size = 64M key_buffer_size = 256M join_buffer_size = 4M read_buffer_size = 4M read_rnd_buffer_size = 4M sort_buffer_size = 8M table_open_cache = 8192 thread_cache_size = 512 tmp_table_size = 384M max_heap_table_size = 384M max_allowed_packet = 1024M query_cache_type=0 query_cache_size=0 innodb_thread_concurrency = 24 innodb_buffer_pool_size = 16G innodb_log_file_size = 384M innodb_log_buffer_size=24M innodb_additional_mem_pool_size = 16M innodb_io_capacity = 800 innodb_concurrency_tickets = 900 innodb_flush_neighbor_pages=cont innodb_lock_wait_timeout=75 innodb_flush_method=O_DIRECT
  22. 22. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – MySQL • Clustering MySQL for Magento Requires all tables to be converted to InnoDB • catalog_full_text_search requires MyISAM, unless your running MySQL 5.7 • When clustering always use identical hardware for each server • Master/Master is not supported by Magento • You can specify read servers and even load balance them • It is unusual for Magento to require a true MySQL Cluster, as it is typically not the bottleneck
  23. 23. Scaling Magento – Mathew Beane - php[world] 2015 Optimizing Hints – Other • Varnish is great, however your application must be suitable • Adding Varnish to a slow site is like putting a bandage on a neck wound • Varnish complicates logging and request tracking throughout the application • Lesti_FPC is a good redis ready FPC for Community Edition. • https://gordonlesti.com/projects/lestifpc/ • CDNs can have a great impact on end-user performance • Reduction in requests is also beneficial to the web server • Typically one of the cheapest/best moves to make • Always test any changes you make

  27. 27. Scaling Magento – Mathew Beane - php[world] 2015 Magento – “Clean Core” Keep a clean core. If you inherit a project, one of the first things you should do is clean up core. This means you have not changed any default files including templates, layouts and code. Ben Marks, Magento Community Evangelist @benmarks (Protector of the Core)
  28. 28. Scaling Magento – Mathew Beane - php[world] 2015 How to Keep Core Clean Source: https://joind.in/talk/view/16204 • Magento allows class overrides on nearly everything. • Magento’s Event/Observer mechanism is pre- built into most business logic. You can add more if you need. • Designs/Templates have a fallback system that allows you to utilize any of the core layouts and templates, or replace them in your current design. • Untouched index.php. Outside of development and very rare implementations you should not “need” to edit this.

  34. 34. Scaling Magento – Mathew Beane - php[world] 2015 Development Cycle • Should apply equally to the hardware architecture as to the software application. • Every project should have a continuous development cycle in place, and ensure that it is well documented and easy to follow for all of the people involved.
  35. 35. Scaling Magento – Mathew Beane - php[world] 2015 Development Cycle - Simplified Design: Plan our your sprint, stick to Agile. Develop: Toward a release on a schedule • Test: Build PHPUnit and Selenium tests into your process • Code Review: Pull requests and code review EVERYTHING. • User Acceptance Tests: Make sure the client is happy first. Deploy: Package, test and deploy. • Deployments: Automate, and make the production servers hands off.
  36. 36. Scaling Magento – Mathew Beane - php[world] 2015 Development Cycle – Agile / Scrum • Goal based system that encourages teamwork. • Daily communications with all involved in project. • Flexible and focused on delivery. • Encourages Teamwork and Accountability.
  37. 37. Scaling Magento – Mathew Beane - php[world] 2015 Development Cycle – Branching • Keep a clean core • Never edit core files. Ensure that you can see any core changes in production . • Release / Feature Branching • Choose a branching methodology and build around it. • Use Pull Request • Code review increases the quality of your code. Make pull requests part of your workflow.
  38. 38. Scaling Magento – Mathew Beane - php[world] 2015 Successful Git Branching Model http://nvie.com/posts/a-successful-git-branching-model/ • Use Tagging as you release to master • Types of branches: • Master: Tagged versions, what's on production. • Develop: What will be merged into master with the next release. • Release: Preparing for release. Allows for last minute fixes, testing and prepping. • Feature: Usually checked out by developers to work on features. • Hotfix: Fixes aimed for unplanned production releases.
  39. 39. Scaling Magento – Mathew Beane - php[world] 2015 Development Cycle – Testing Build testing into all of your development cycles. Developers are working on testing with Magento 1 BDD: https://speakerdeck.com/alistairstead/bdd-with-magento BeHat: https://github.com/MageTest/BehatMage PHPSpec: https://github.com/MageTest/MageSpec Magento 2 has a built in Test Automation Framework ( PHPUnit,Selenium ) https://wiki.magento.com/display/MAGE2DOC/Magento+Automated+Testing+Guide https://github.com/magento/taf https://alankent.wordpress.com/2014/06/28/magento-2-test-automation/
  40. 40. Scaling Magento – Mathew Beane - php[world] 2015 Do Not Edit on Production • Use a deployment tool, and LOCK DOWN production. No one should ever have to touch an application file manually for any reason. • If you can extend this practice to your OS and server stack you now have fully engaged DevOps.
  41. 41. Scaling Magento – Mathew Beane - php[world] 2015 Development Cycle – Testing (Example of Fail) After introducing SOLR indexing, testing showed serious issues as it indexed.
  42. 42. Scaling Magento – Mathew Beane - php[world] 2015 Development Cycle – Application Packaging • You must be able to package your application in order to deploy it to a cluster. • Deployment infrastructure may determine what packaging you will need to use, for instance one of the following: • Zend Server offers Application Packaging and Deployment • A simple “golden copy” (tgz or flat) that is pushed to web nodes. • RPM or other proprietary packaging tool. • Use Composer and/or modman to help maintain your application packages. • Composer can even be used to install Magento Core • Make sure your build process is repeatable and testable.

  44. 44. Scaling Magento – Mathew Beane - php[world] 2015 Deployment Tools – Typical Software • When deploying an application to a cluster of application servers, a deployment tool is a requirement. • There are many choice, here are a couple typical deployment tools. • Capistrano: Written in Ruby but well accepted and great to work with • Jenkins: Another example of Deployment Automation • Bamboo: Part of the Atlassian stack also includes testing and other features. • Roll Your Own: This is more common, using bash scripts and other tools you can build a project deployment tool fairly easily.
  45. 45. Scaling Magento – Mathew Beane - php[world] 2015 Deployment Tools – Some Requirements • Integrated with code versioning • Supports Multi-Server • Supports the Application • Handles Maintenance Mode automatically • Runs Installers • Clears Caches • Low Downtime • Rollback Procedure (a/b switch) • Trigger events such as shell scripts, or CDN clearing • Nice to have – May not be required • Integrated testing • Packaging • Integration to GUI Interfaces Deploying applications manually is a lot of work.
  46. 46. Scaling Magento – Mathew Beane - php[world] 2015 Deployment Tools – Further Study I highly suggest researching Fabrizio Branca’s work on the subject: http://www.slideshare.net/aoepeople/rock-solid-magento Fabrizio has a ton of articles and slideshares on the subject.

  56. 56. Scaling Magento – Mathew Beane - php[world] 2015 Load Testing Production 1. Prepare a downtime: Forward site to a non-magento maintenance page Exclude Testing IP – So tests can still proceed Disable Cron 2. Copy Production Database 3. Point Magento at the new copied DB 4. Modify Magento Admin Settings in copied DB Use Test Payment Gateway Disable Transaction Emails 5. Test against Copied DB 6. After Testing is complete: Point site at original DB Put site back up on live Enable Cron Using this method, you can test against production on production. You will need to bring the site down during the time period, but if this is done at a low point in traffic it causes little to no stress to the customers.
  57. 57. Before You Start Clustering Optimized Server Settings Magento application is optimized and clean Development pipeline in place Deployment infrastructure is solid Rigorous testing protocols are in place Pre-Scaling Checklist Next Up: Discussion about typical cluster architecture and components
  58. 58. Magento Cluster Architecture
  59. 59. Scaling Magento – Mathew Beane - php[world] 2015 Magento Cluster Architecture – Typical Layout • Load Balanced – Front End Webservers • Admin / Backend Server Separated • Single MySQL Database Master, with Slaves
  60. 60. Scaling Magento – Mathew Beane - php[world] 2015 Magento Cluster Architecture - Components Web Servers • Apache / Nginx • PHP 5.4 + (depends on Magento Version) • Multiple Webservers – Easy to cluster • Varnish Can be used as a Reverse Proxy • Nexcess Turpentine is the standard Magento Extension • Magento2 has Varnish support out of the box
  61. 61. Scaling Magento – Mathew Beane - php[world] 2015 Magento Cluster Architecture - Components Database • MySQL / Percona • Master / Slave • Slaves are typically used for reporting or Hotswap for failure • Can be set to read servers for application, but it requires some work • Solr / Elastic Search • Typically run on the Database or Backend Server • Can power Search or other Magento business logic
  62. 62. Scaling Magento – Mathew Beane - php[world] 2015 Magento Cluster Architecture - Components Other Components • File Server • NFS – This is by far the most common • NAS – Can be used on high end clients • Redis / Memcache • Deployment Tools • Monitoring • ELK – Log aggregation across servers • Puppet / Chef
  63. 63. Scaling Magento – Mathew Beane - php[world] 2015 Magento Cluster Architecture - Bottlenecks Breaking Points, where you need to adjust first. 1. PHP – More web nodes, easy to do and very performant. 2. Filesystem – Use a CDN to offset static asset traffic. 3. Redis – Cluster Redis using sentinel/nutcracker. 4. Database – Look at read server clustering At some point adding Varnish should be considered as well. Varnish requires a clean application with some thought as to which blocks can be loaded dynamically via AJAX.
  64. 64. Scaling Magento – Mathew Beane - php[world] 2015 Scaling Implementation – A Scoring System Concern Score (1-5) What is the simplicity of the solution? How difficult is it to support? Is it extensible, how broadly does it apply? Will it break often? How easy is it to update? Is it Expensive? Concern Yes / No Does it require specialized services? (os level services, not typically installed) Does it require Magento application changes? Does it create a single point of failure? Yes = 5 Points, No = 0
  65. 65. Scaling Magento – Mathew Beane - php[world] 2015 Scaling – Web Server Concerns • Simple to Load Balance, most sites start here • Challenges include the following: • Session Management: should be a no brainer if your using redis for sessions • Shared file System: Use NFS for media, keep all code local to web servers • Fencing: easily solved with either software or hardware • Log Collection: ELK, Rsyslog or Splunk • Keep the system builds simple, repeatable and automate if possible
  66. 66. Scaling Magento – Mathew Beane - php[world] 2015 Scaling – Web Server Concerns (Automation) How to automate:  Create an complete image to work from - include puppet so it can pull from a puppet master  The puppet master spins up your webserver stack  You have your deployment process in place, so deploy the application and spin up the node Things of Note: • Be prepared to lose nodes, the more you have the more likely failure is • When a node runs amok, you must be prepared to kill it dead • Webservers typically wont fail, and fencing is more of an issue with db/redis.
  67. 67. Scaling Magento – Mathew Beane - php[world] 2015 Scaling - File systems Best practice for sharing files: Use NFS • Most other options are not viable. (glusterfs, iscsi, and so on) • NFS will not be the bottleneck if your application is configured correctly • Share only media/ to avoid bottlenecks • Client requirements may drive cluster toward a NAS Network Attached Storage (NAS) • Typically only on very large sites • Expensive but very reliable and robust • Entry level has very high bar (typically 20+ drives)
  68. 68. Scaling Magento – Mathew Beane - php[world] 2015 Scaling – File Systems and Symbolic Links • Share specific folders via symbolic links • Maintaining these when deploying is easy, just remake symbolic links or copy them • Mount /var/magento/shared/[directory] via NFS, typically served from backend server • Example: [docroot]/media -> /var/magento/shared/media • Can also be used for local content • Not mounted via NFS, writes local var files for this server only • Example: [docroot]/var -> /var/media/local/var
  69. 69. Scaling Magento – Mathew Beane - php[world] 2015 Scaling – Redis Clustering “Redis clustering using sentinel is easy to set up. Adding twemproxy allows for a highly scalable Redis cluster and you get auto fail over and a ton of other benefits with this configuration. This arrangement can also remove your Redis single point of failure.” http://aepod.com/clustering-magento-redis-caching-with-sentinel-keepalived-twemproxy-and-twemproxy-agent/ • Easy to setup… well not really • Very Complex, requires orchestration • Sentinel Monitors Redis clusters • twemproxy handles sharding • twemproxy agent monitors sentinel • Very robust when setup, nothing is single threaded, everything is HA and the speed…. • Can be transparent to Magento despite the complexity
  70. 70. Scaling Magento – Mathew Beane - php[world] 2015 Redis (Sentinel / twemproxy) Requires several layers of applications • Load Balancer: Load balances redis traffic to the twemproxy servers • Twemproxy: proxy server, typically setup as a cluster of 2 servers (can be mixed on other servers) • Nutcracker Agent: Connects twemproxy to sentinel to keep track of shards of servers • Sentinel: Monitors the redis instances and maintains availability • Redis: Dozens of redis servers, sharded, maintained and fenced by Sentinel and nutcracker • VERY Complex
  71. 71. Scaling Magento – Mathew Beane - php[world] 2015 Scaling - MySQL • Should be considered a low value target, except for High Availability concerns because Magento typically is not bottlenecked by MySQL • Using Percona XtraDB you can add read slaves • Magento only supports a single Master/Write server, with multiple read servers • Setting up load balanced READ db servers is not overly difficult, but doesn’t offer much if any performance benefits • Cluster DB will require more advanced fencing • Typical production sites do not use load balanced or clustered MySQL
  72. 72. Scaling Magento – Mathew Beane - php[world] 2015 Database Servers (Percona) • Percona XtraDB to cluster MySQL • Percona XtraBackup for duplicating and rebuilding nodes • Percona Toolkit to help debug any issues your running into • Difficult to scale Write Servers • Scale out your read servers as needed, but MySQL reads are rarely the bottleneck • Typically Slave server is used for backup and hot swap, NOT clustering. A couple quick tips: • Not all tables in Magento are InnoDB, converting the MyISAM and Memory tables is OK • You will need to be able to kill read servers and refresh them. (Percona XtraBackup) • Use your Master server as a read server in the load balancer pool, when you kill all your read servers, it can fall back to master.
  73. 73. Scaling Magento – Mathew Beane - php[world] 2015 Magento Cluster Architecture – Additional Tools Load Balancer Components • Hardware Load Balancer • HAProxy Software Load Balancer Database Components • Sentinel / Nutcracker • Percona XtraDB Tools • Clusterix or ScaleARC for High End
  74. 74. Scaling Magento – Mathew Beane - php[world] 2015 Load Balancers – Software / HAProxy • HAProxy: a free fast and reliable solution featuring high availability, load balancing and proxy for TCP and HTTP-based applications. • HAProxy can be used for web servers, database servers, Redis and any other TCP based application. • Easy to configure using a puppet module • Can be clustered easily for high availability concerns • Handles L4 Load Balancing if you want to do fancy multi-application environments • Built in stats interface SOFTWARE
  75. 75. Scaling Magento – Mathew Beane - php[world] 2015 Hardware Load Balancers • F5 Hardware load balancers are a standard • Brocade is another common brand • Rackspace offers a very easy to use web interface to maintain a hybrid infrastructure • Hardware load balancers offer a turn-key mature solution. • Typically Managed Service, with very hands off approach. HYBRID Hybrid Load Balancers • AWS Elastic Load Balancers • Rackspace Cloud Load Balancers • Cloudflare • Many others… Load Balancers – Hardware & Hybrid
  76. 76. Scaling Magento – Mathew Beane - php[world] 2015 Load Balancers – Making a choice • Budget concerns will drive this decision • Hosting Choices will affect availability, costs and toolsets • Start locally with HAProxy and build test clusters using vagrant • HAProxy can still be used, even with a hardware load balancer in place.
  77. 77. Scaling Magento – Mathew Beane - php[world] 2015 Scaling - Others • Reverse Proxy: Varnish or Nginx you can and should cluster these • Puppet likes to be clustered: Mastering Puppet by Thomas Uphill is a great reference • Monitoring Tools: You’re running these single threaded, what if the monitoring server fails? • Warehouse Integrations, ERP Layer Stuff, everything may need to be multi-threaded • Search back ends such as solr or elasticsearch • Consider all of the parts of the business that surrounds the Magento Application and try to encapsulate them
  78. 78. Scaling Magento – Mathew Beane - php[world] 2015 Reverse Proxy (Varnish) Scaling Concerns Turpentine is the standard go to extension for Magento to tie to Varnish • Handles ESI • Handles Dealing with updating VCL • http://www.magentocommerce.com/magento-connect/turpentine-varnish-cache.html • Varnish will replace your FPC, toggle it FPC off if you are using varnish • https://github.com/nexcess/magento-turpentine/wiki/Installation • Typically Varnish will run on each render box, and proxy to the local nginx. • Issues will typically show up as over caching of blocks or other bits of front end page • SSL is NOT supported by varnish, terminate it at your load balancer
  79. 79. Scaling Magento – Mathew Beane - php[world] 2015 Reverse Proxy (Nginx) Scaling Concerns • NGINX is a great reverse proxy and load balancer • http://nginx.com/resources/admin-guide/reverse-proxy/ • Can be used to effectively buffer and split requests to different cluster servers
  80. 80. Scaling Magento – Mathew Beane - php[world] 2015 Auto-Scaling Strategy • Insert puzzle building analogy joke here: http://www.wikihow.com/Assemble-Jigsaw- Puzzles • Each hosting environment has its own quirks and add on top of that the business logic requirements you will almost always have a unique infrastructure for every client • Build small pieces and work them into the larger picture, you can get a lot of performance with a few minor changes. • Test everything you do, keep detailed notes on the configurations and compare against the previous tests

Scaling Magento – Mathew Beane - php[world] 2015 Magento Performance Toolkit – generate.php • Importing can take a long time, and may require changes to php and MySQL settings • If it fails, it fails hard. Restart with a fresh DB • You can modify the profiles to better suite your testing requirements • Using the toolkit requires putting it in the dev/tools/performance_toolkit/ directory in the Magento install you want to use it on • The scripts requires this exact directory, due to includes and autoloading • Oftentimes will require you to remove the tmp dir inside the toolkit
  84. 84. Scaling Magento – Mathew Beane - php[world] 2015 Magento Performance Toolkit – Generate Profiles • You can create your own profiles by copying and modifying the XML in profiles/ • Large and X-Large take extremely long times to import and require changes to the PHP and MySQL settings and it still likes to fail hard. • After it completes import, double check the following • Front end still up and running and shows the framework categories • Admin and Frontend logs in correctly • Indexes and Caches rebuild correctly

  88. 88. Scaling Magento – Mathew Beane - php[world] 2015 Magento Performance Toolkit –Users Demystified The JMeter tests use 4 thread groups to accommodate the testing. • Category Product Browsing(30%): Opens the homepage, goes to a category, opens up 2 simple products and then a configurable. • View Product Add To Cart(62%): Same as Category browsing however it adds each of the items to the cart in addition to viewing them. • Guest Checkout (4%): Same as View/Add to Cart, in addition it runs through the checkout as a guest user. • Customer Checkout (4%): Same as View/Add to Cart, in addition it runs through the checkout as a logged in customer. Thread groups create threads based on the number of users and the above percentages(by default). users * group_percent / 100 • This result is rounded down, and can be 0 for checkouts, making no checkout threads. • You can set EACH group independently, and they do not need to add up to 100% or less in totality.
  89. 89. Scaling Magento – Mathew Beane - php[world] 2015 Magento Performance Toolkit – More Attributes Any JMeter Attribute from top level can be set from command line using –Jattribute= Customer and Admin Password must match what was used during the generate. Orders are tricky and used to calculate “users” which are used within the thread groups. See jmeter test setup Thread Group -> validate properties and count users

Customer Checkout Teardown 1. Just removes some stats, but you could extend this spot for some killer stats. jMeter test, building the current test. Notice it takes quite a few requests to get started. jMeter tests running, you can see the “customer count” decrementing as it runs through the tests.

Scaling Magento – Mathew Beane - php[world] 2015 Magento Performance Toolkit – Maxed Orders ./jmeter -n -t ~/benchmark-default.jmx -Jhost=www.idealphp.com -Jbase_path=/ -Jusers=10 -Jramp_period=30 -Jreport_save_path=./ -Jloops=2000 -Jadmin_password="5678password" -Jadmin_user=admin -Jview_product_add_to_cart_percent=0 -Jview_catalog_percent=0 -Jcustomer_checkout_percent=0 -Jguest_checkout_percent=100 (This can be done in the JMX as well) Non-Trivial Settings: View Catalog : 0% View Product Add to Cart : 0% Customer Checkout: 0% Guest Checkout: 100% This test will slam orders through as fast as it can. Using it is as simple as recording the number of orders at the start and finish of a test, and then calculating the number of orders per hour on that. Orders Per Hour = (3600 / Time to Complete) * (Ending Orders – Starting Orders)
  95. 95. Scaling Magento – Mathew Beane - php[world] 2015 Magento Performance Toolkit – In Production To use the Magento Performance Toolkit on a existing built out production website: 1.Follow the testing on a production site plan from earlier. 2.Ensure your top-menu matches the JMeter tests search for top_menu, you can switch the jmeter test or try to modify the template to match. 3.Modify the generate script to not create categories 4.Generate your data 5.Run your tests Other Issues: Not a trivial issue, it will take some time to setup. Checkout and cart parts probably will fail and require changes to tests Not the cleanest methodology, but it does work if you make the effort
  96. 96. Scaling Magento – Mathew Beane - php[world] 2015 Magento Performance Toolkit – Benchmarking • Find metrics to base any decisions you make, and quantify the results • 30 Threads per web head is a good spot to start (except in the VM) • Orders Per Hour • Collect test start and end orders • (end orders – start orders) * (3600 / time to complete) • Customers Per Day • (86400 / time to complete) * Online Customers
  97. 97. Scaling Magento – Mathew Beane - php[world] 2015 Magento Performance Toolkit – Benchmarking • Max Response Time: Should stay below 10 seconds in a good test • Average Response Time: Should be below 500ms in a good test • Error Rate: 0.00% is what your looking for, some glitches may happen • Collect New Relic Stats or other stats and use them to supplement the tests
