  "top 1 million" websites
• As of August 2011 WordPress powers 22% of all
  new websites
• As of December 2011, version 3.0 had been
  downloaded over 65 million times
• Provide some architectural insights to build Highly
  Scalable and Available WordPress sites in AWS
• Help startups and companies who are new to AWS-
  WordPress with some blueprints
WordPress Architecture Requirements in
                  AWS
• Ability to Serve millions of Pages per day
• Ability to scale out/down dynamically depending
  upon traffic
• Ability to perform well even with scaling demands
• Should be Highly available without Single Points of
  Failure
• Automated Operations – Backup and Monitoring
• Cost effective
Why AWS is better for WordPress Scaling?

• AWS provides flexibility to Scale up and Scale out
• AWS provides Building block services which is
  inherently robust and fault tolerant
• AWS provides full range of options from CDN , OS
  flavors , Storage Pool , Database , Load Balancers ,
  Monitoring etc
• Pay as you go – Save cost by leveraging Auto Scaled
  WordPress EC2 instances
• We can start small and grow big in AWS

Load Balancing with Amazon ELB

• Amazon Elastic Load Balancing will Load balance the
  http requests to WordPress EC2 instances
• ELB will direct the requests to WordPress EC2 across
  Multiple Availability Zones ( for HA)
• Health check , LB algorithms and SSL termination
  will be done by the Load Balancer
• Amazon Elastic Load Balancing can keep expanding
  its capacity automatically depending upon the
  traffic
Load Balancing with Amazon ELB

• Amazon ELB works with Route 53 and Auto Scaling
  seamlessly
• Amazon ELB is priced @“ Pay for use” model
• Amazon ELB is a managed service , so
  • NO Maintenance headaches
  • NO SW/HW upgrades
  • NO Capacity planning
  • NO manual intervention for expansion

Scalability and Elasticity

• Scalability and Elasticity is built in most of the layers
  in this architecture
• WordPress EC2 instances can be scaled out and
  down depending upon the traffic
  • We can expand the number of WordPress EC2 instances from 1 to
    100+ automatically during load peaks
  • We can reduce the number of WordPress EC2 instances from 100+
    to 1 automatically during valleys
  • Can serve millions of pages with ease
  • Pay only for the EC2 instance hours used
Scalability and Elasticity

• Read Scalability is built in the Database layer with
  RDS Read Replicas
• New RDS Read Replicas can be added / removed
  with ease
  • Tips:
     • During Campaigns alone we can run more RDS Read Replicas
     • Not more than max 5 RDS Read replicas are recommended
     • Keep Read Replica’s and RDS Master same EC2 size for better
       performance
Scalability and Elasticity

• Clustered + Distributed File System of the Storage
  pool layer can be manually scaled in case needed
  • Minimum 2 EC2 Large instances should be used for
    Storage Pool Layer ( for HA and better IO)
  • Design the Storage Pool Layer with HA (very critical)
• AWS building blocks like S3 , CloudFront ,
  CloudWatch , SNS used in this architecture are
  inherently designed for scalability
How High Availability and Fault tolerance is
        built in this Architecture ?
High Availability

• HA @ WordPress Layer
  • Multiple WordPress EC2 instances avoid single point of
    failure
  • WordPress EC2 instances are launched across multiple –
    AZ’s inside a region for High Availability
• HA @ DB Layer
  • RDS MySQL Master and Standby are launched in 2
    different availability zones for High Availability
  • RDS Read Replicas are created in Multiple –AZ’s
High Availability

• HA @ Storage Pool Layer
  • Two EC2 instances used for Storage Pool Layer
  • Storage Pool is setup in replicated mode for High
    Availability
• AWS building blocks like S3 , Cloud Front ,
  CloudWatch , ELB , SNS ,EBS used in this
  architecture are inherently designed for Fault
  tolerance and HA

• RDS Master and Standby provide High availability
• RDS Read Replicas provide Read performance
• HyperDB plugin is configured to use multiple
  endpoints like RDS master and RDS read replicas in
  this architecture
• DB security groups will allow DB access only to
  WordPress EC2 instances
• Periodic Dumps , Snapshots and Point in time
  recovery is possible in this architecture
What performance aspects are taken care in
            this Architecture ?
Performance

• APC (or) Xcache plugin can be used for PHP opscode
  caching
• W3TotalCache+CloudFront (or)
  BatCache+Memcached can be used for Page
  caching
• Multiple RDS Read Replicas for Read performance
• RDS Master and Read Replicas are separated to get
  independent write and read performance
• Amazon ELB + Auto Scaling improves the overall Site
  performance when the load increases

Backup

• Custom ops scripts will backup the necessary files
  from Storage pool to S3 periodically
• S3 can be configured to remove old backups
  automatically
• RDS MySQL is configured to take periodic data
  dumps and DB snapshots
• RDS layer can be recovered point in time from the
  backups
Security

• Suitably hardened OS for WordPress Mgmt and
  WordPress instances
• Firewall (or) AWS security groups configured
  between all the layers in the architecture
• SFTP/FTP access only to the WordPress
  management node
• AWS IAM policies to manage user account access
• Install WordPress Security plugins
Advantages

• Highly Available and Scalable architecture
• Can elastically scale out to serve millions of hits in
  a day
• Can grow with load demands in future
• Usage of inherently fault tolerant AWS building
  blocks adds Stability
• High performance using CDN and suitable cache
  plugins
• Monitoring , Backup and Recovery is built in
• Pay for use
Disadvantages

• Complex to setup and maintain
• Will not be ideal for smaller sites that do not need
  scale
• Will not be cost efficient for sites that have less
  traffic
Key Points to Remember

• Log files generated in WordPress EC2 instances have
  to rotated
• Use Amazon EBS for Storage Pool and WordPress
  EC2 instances
• Start with EC2 m1.Large Instances for the storage
  pool and WordPress instances
• More Memory – Better Performance for DB
  • Start with RDS Large for Master
  • Keep RDS Master and RDS Read Replica’s in same size to
    improve read performance
Key Points to Remember

• RDS MySQL supports only Innodb engine
• Separate the WordPress Management and
  WordPress Content instances for scalability
• Do not Scale out/down rapidly in a hour, it will cost
  more in AWS
• Combine AWS On-Demand and Reserved Instance
  pricing to get more savings per month
Key Points to Remember

• Amazon Availability Zones(AZ’s) are distinct physical
  locations with Independent power , cooling
  ,network and security having Low latency network
  connectivity between them inside the same region
  • Leverage them in WordPress , Storage Pool and DB layers
    for HA as mentioned in the architecture
How do I setup Scalable WordPress
architecture on AWS?
Leave it to the experts , we will
handle this

  • 17. Scalability and Elasticity • Scalability and Elasticity is built in most of the layers in this architecture • WordPress EC2 instances can be scaled out and down depending upon the traffic • We can expand the number of WordPress EC2 instances from 1 to 100+ automatically during load peaks • We can reduce the number of WordPress EC2 instances from 100+ to 1 automatically during valleys • Can serve millions of pages with ease • Pay only for the EC2 instance hours used
  • 18. Scalability and Elasticity • Read Scalability is built in the Database layer with RDS Read Replicas • New RDS Read Replicas can be added / removed with ease • Tips: • During Campaigns alone we can run more RDS Read Replicas • Not more than max 5 RDS Read replicas are recommended • Keep Read Replica’s and RDS Master same EC2 size for better performance
  • 19. Scalability and Elasticity • Clustered + Distributed File System of the Storage pool layer can be manually scaled in case needed • Minimum 2 EC2 Large instances should be used for Storage Pool Layer ( for HA and better IO) • Design the Storage Pool Layer with HA (very critical) • AWS building blocks like S3 , CloudFront , CloudWatch , SNS used in this architecture are inherently designed for scalability
  • 20. How High Availability and Fault tolerance is built in this Architecture ?
  • 21. High Availability • HA @ WordPress Layer • Multiple WordPress EC2 instances avoid single point of failure • WordPress EC2 instances are launched across multiple – AZ’s inside a region for High Availability • HA @ DB Layer • RDS MySQL Master and Standby are launched in 2 different availability zones for High Availability • RDS Read Replicas are created in Multiple –AZ’s
  • 22. High Availability • HA @ Storage Pool Layer • Two EC2 instances used for Storage Pool Layer • Storage Pool is setup in replicated mode for High Availability • AWS building blocks like S3 , Cloud Front , CloudWatch , ELB , SNS ,EBS used in this architecture are inherently designed for Fault tolerance and HA
  • 23. How the Database Tier is Architected ?
  • 24. Admin Amazon AZ : Amazon Amazon CloudFront Availability Zones Route 53 AWS Region 1 Static Data SSH/SFTP Elastic Load S3 Balancer Amazon CloudWatch Az-1 Az-2 Alarms Auto Scaled WordPress EC2 WordPress instances Management Server Amazon SNS Notifications Az-1 Az-2 Az-1 Az-2 Standby RDS Master Read Replica Backups and Log files File Storage Pool Database Layer Database Layer
  • 25. Database layer • RDS Master and Standby provide High availability • RDS Read Replicas provide Read performance • HyperDB plugin is configured to use multiple endpoints like RDS master and RDS read replicas in this architecture • DB security groups will allow DB access only to WordPress EC2 instances • Periodic Dumps , Snapshots and Point in time recovery is possible in this architecture
  • 26. What performance aspects are taken care in this Architecture ?
  • 27. Performance • APC (or) Xcache plugin can be used for PHP opscode caching • W3TotalCache+CloudFront (or) BatCache+Memcached can be used for Page caching • Multiple RDS Read Replicas for Read performance • RDS Master and Read Replicas are separated to get independent write and read performance • Amazon ELB + Auto Scaling improves the overall Site performance when the load increases
  • 29. Admin Amazon AZ : Amazon Amazon CloudFront Availability Zones Route 53 AWS Region 1 Static Data SSH/SFTP Elastic Load S3 Balancer Amazon CloudWatch Az-1 Az-2 Alarms Auto Scaled WordPress EC2 WordPress instances Management Server Amazon SNS Notifications Az-1 Az-2 Az-1 Az-2 Standby RDS Master Read Replica Backups and Log files File Storage Pool Database Layer Database Layer

Advantages • Highly Available and Scalable architecture • Can elastically scale out to serve millions of hits in a day • Can grow with load demands in future • Usage of inherently fault tolerant AWS building blocks adds Stability • High performance using CDN and suitable cache plugins • Monitoring , Backup and Recovery is built in • Pay for use
  • 40. Disadvantages • Complex to setup and maintain • Will not be ideal for smaller sites that do not need scale • Will not be cost efficient for sites that have less traffic
  • 41. Key Points to Remember • Log files generated in WordPress EC2 instances have to rotated • Use Amazon EBS for Storage Pool and WordPress EC2 instances • Start with EC2 m1.Large Instances for the storage pool and WordPress instances • More Memory – Better Performance for DB • Start with RDS Large for Master • Keep RDS Master and RDS Read Replica’s in same size to improve read performance
  • 42. Key Points to Remember • RDS MySQL supports only Innodb engine • Separate the WordPress Management and WordPress Content instances for scalability • Do not Scale out/down rapidly in a hour, it will cost more in AWS • Combine AWS On-Demand and Reserved Instance pricing to get more savings per month
  • 43. Key Points to Remember • Amazon Availability Zones(AZ’s) are distinct physical locations with Independent power , cooling ,network and security having Low latency network connectivity between them inside the same region • Leverage them in WordPress , Storage Pool and DB layers for HA as mentioned in the architecture
  • 44. How do I setup Scalable WordPress architecture on AWS?
  • 45. Leave it to the experts , we will handle this Cloud Architecture Consulting Cloud Application Development Cloud Migration & Implementation Cloud Adoption Strategy “Let's get the job done”
