It provides an example of using Chef cookbooks to configure a Memcached server. It also describes how a company called Peritor uses tools like Chef and Amazon EC2 to automate management of a social networking site called Monster World, which sees peak loads of 130 servers and 240,000 requests per minute. The document encourages trying out automation tools from Scalarium.
Continuous Deployment with Cloud Foundry, Github and Travis CI
Continuous deployment allows developers to automatically deploy code changes to Cloud Foundry after tests pass. The process involves setting up Travis CI to run tests on code commits and deploy to Cloud Foundry if tests succeed, allowing developers to focus on code quality without worrying about manual deployments. Setup takes less than 10 minutes by connecting Travis to Cloud Foundry and configuring automatic test execution and deployments for a smooth, reliable continuous deployment process.
AWS meets Continuous Delivery
Talk by Alex Krause and Andreas Mohrhard
devopscon 2016 - Munich

Ein großer Vorteil von AWS Lambda gegenüber anderen Serverless-Diensten ist die gute Integration in die bestehenden AWS-Dienste. So kann beispielsweise auf eingehende E-Mails über den Simple Notification Service (SNS) ebenso reagiert werden, wie auf neu hochgeladene Dateien in S3. Um davon profitieren zu können, müssen Lambda-Funktionen entsprechend konfiguriert werden. Bei Applikationen jenseits der üblichen Beispiele wird dies schnell sehr komplex und fehleranfällig, umso mehr, wenn die Lambda-Funktionen mit AWS API Gateway über HTTP angesprochen werden. Im Vortrag wird am Beispiel einer Single-Page-Applikation gezeigt, wie man in einem Serverless Backend von unterschiedlichen AWS-Diensten profitieren kann und dabei die Konfiguration der unterschiedlichen Lambda-Funktionen und von AWS API Gateway im Griff behält. Mithilfe von CloudFormation, Apex, Serverless oder Terraform kann all das automatisiert und in einen CI-/CD-Prozess integriert werden. Der Vortrag gibt einen Überblick über die unterschiedlichen Möglichkeiten und zeigt konkrete Lösungen.

Docker
This document compares classic app development and deployment to containerized apps. It discusses using containers and Docker to package apps and their dependencies. It shows how containers can be defined, built, and orchestrated. Container deployment to different environments like integration, staging, and production is described. Usage scenarios like continuous integration servers are presented. Challenges with the new container-based approach are also acknowledged.
Keep your projects up-to-date
If you have an app bootstrapped with [create-react-app](https://github.com/facebook/create-react-app), you may have a certain amount of boilerplate code that came with it, especially if you ejected. Now you may want to sync up with the latest changes in create-react-app. I've ported [ember-cli-update](https://github.com/ember-cli/ember-cli-update) to [create-react-app-updater](https://github.com/kellyselden/create-react-app-updater) to get the same benefits for react apps. You can keep your pojects in sync as well as run codemods based on react version.
Romulus crisan + radu pascal click'n'deploy
The document discusses automating the software deployment process through continuous integration and continuous deployment techniques. It recommends using source control systems like TFS or Git and building projects with a build server. A build server can be set up on-premises or using a hosted build service like Visual Studio Online. Once projects are built, a deployment tool like Octopus Deploy can be used to automatically deploy packages to test and production environments. The automated process helps reduce errors and provides deployment history and visibility.

Serverless in Production, an experience report (AWS UG South Wales)
AWS Lambda has changed the way we deploy and run software, but this new serverless paradigm has created new challenges to old problems - how do you test a cloud-hosted function locally? How do you monitor them? What about logging and config management? And how do we start migrating from existing architectures?
In this talk Yan and Scott will discuss solutions to these challenges by drawing from real-world experience running Lambda in production and migrating from an existing monolithic architecture.
Serverless in production, an experience report (Going Serverless, 28 Feb 2018)
This document discusses best practices for preparing serverless applications on AWS Lambda for production. It describes the author's experience deploying 170 Lambda functions and 1.2GB of code into production with a 95% cost savings compared to EC2. Key practices covered include testing, monitoring, logging, distributed tracing, CI/CD pipelines, configuration management, and security. The author advocates for building on principles over tools and shares several tools for serverless development.
Docker: automation for the rest of us
Docker landed almost two years ago, making it possible to build, ship, and run
any Linux application, on any platform, it was quickly adopted by developers
and ops, like no other tool before. The CI/CD industry even took it to
production long before it was stamped "production-ready."
Why does everyone (or almost!) love Docker? Because it puts powerful
automation abilities within the hands of normal developers. Automation
almost always involves building distribution packages, virtual machine
images, or writing configuration management manifests. With Docker,
those tasks are radically transformed: sometimes they're far easier than before,
other times they're no longer needed at all. Either way, the intervention
of a seasoned sysadmin guru is no longer required.
Game of Codes: the Battle for CI

It also provides information about DAZN, an online sports streaming service, and mentions that they are hiring.
Achieving Continuous Delivery: An Automation Story
Continuos Deployment is the act of deploying software constantly. The idea is if "release early, release often" is good, releasing very often is better. It's not trivial. Automation is part of the battle, and testing is another. Learn to use tools like Jenkins and Ansible to move from deploying software once a month to 15 times every hour, and why you'll want to.
Presented at PyCon 2015 in Montreal
DevOps For Small Teams
DevOps is a large part of a company of any size. In the 9+ years that I have been a professional developer I have always taken an interest in DevOps and have been the "server person" for most of the teams I have been a part of. I would like to teach others how easy it is to implement modern tools to make their everyday development and development processes better. I will cover a range of topics from "Stop using WAMP/MAMP and start using Vagrant", "version control isn't renaming files", "Automate common tasks with shell scripts / command line PHP apps" and "From Vagrant to Production".
Serverless in production, an experience report (FullStack 2018)
This document discusses considerations for making serverless applications production ready. It covers topics like testing, monitoring, logging, deployment pipelines, performance optimization, and security. The document emphasizes principles over specific tools, and recommends focusing on shipping working software through practices like embracing external services for testing instead of mocking.
100% Puppet Cloud Deployment of Legacy Software
This document discusses deploying legacy software into the AWS cloud using Puppet. It proposes modeling AWS resources like security groups, autoscaling groups, and launch configurations as Puppet resources. This would allow Puppet to provision the underlying AWS infrastructure and configure servers launched in autoscaling groups. It acknowledges challenges around server reboots but suggests they can be addressed. In summary, it argues custom Puppet resources can easily model AWS resources and using Puppet to configure autoscaling servers is possible despite some challenges around rebooting servers during deployment.

2) By managing all infrastructure as code in Git, and avoiding server state, Percolate's infrastructure is resilient and can be migrated or changed easily.
3) This stateless approach means Percolate avoids backup overhead and can freely launch/replace instances, reducing costs through use of spot instances.
BTD2015 - Your Place In DevTOps is Finding Solutions - Not Just Bugs!
This is about leveling-up and REVOLUTIONIZING Testing as part of your Agile/DevOps Transformation.
You can contribute more than testing functionality. You need to Level-Up your skill set by understanding the apps you are testing. # Images, # JS Files, # SQL Statements, Connection Pool Utilization and Garbage Collection Activity have to be added to your portfolio.
Check these metrics when you do your functional testing and report regressions to your engineers even though the functionality is still good. But you just uncovered an Architectural regression that will lead to a scalabilty and performance problem.
Finding these problems early will eliminate a lot of wasted and unplanned time later on in the lifecycle. that is your contribution to delivering software faster with better quality

Eric Proegler Oredev Performance Testing in New Contexts
Virtualization, Cloud Deployments, and Cloud-Based Tools have challenged and changed performance testing practices. Today’s performance tester can summons tens of thousands of virtual users from the cloud in a few minutes at a cost far lower than the expensive on-premise installations of yesteryear.
Meanwhile, systems under test have changed more. Updated software stacks have increased the complexity of scripting and performance measurement, but the biggest changes are in the nature and quantities of resources powering the systems. Interpreting resource usage when resources are shared on a private virtualization platform is exceedingly difficult. Understanding resources when they live in a large public cloud is impossible.

A Build Engineering Team’s Journey of Infrastructure as Code - the challenges that we’ve faced and the practices that we implemented as we went along our journey.
stackconf 2022: Infrastructure Automation (anti) patterns
Over the past 1.5 decade our industry has tried to adopt an increased amount of infrastructure automation. We called it Configuration Management, Infrastructure as Code, infrastructure as Software, Provisioning, Orchestration. We learned about Desired State, Idempotence, etc.. We have seen a number of tools become popular; we have seen a number of tools disappear. But over the years we have seen a number of patterns appear and reappear. Patterns that lead to actually getting great benefits out of automation, or just wasting time while missing out on goals. This talk will explain you a number of these patterns which we have frequently encountered in the wild, with their benefits and caveats. We will try to keep this tool agnostic. Your vision might be Clouded, and you might have to take this with a grain of Salt while you play the Chef from the Muppet show the story, all names, characters, and incidents portrayed in this production are fictitious. No identification with actual persons (living or deceased), places, buildings, and products are intended or should be inferred.
Infrastructure as Code Patterns
StackConf 2022 Talk about The Different Patterns and AntiPatterns
we've seen over the past decade of Automation
Greenfields tech decisions
Trent Hornibrook gave a recent talk at the Infracoders meet-up playing a thought experiment with the audience on 'what would be your tech decisions if you were given a blank cheque at at startup'.
Trent, recently working for a start-up then shared what decisions he made, and why
Continuous Deployment To The Cloud @DevoxxPL 2017
Spring Cloud Pipelines provides an opinionated template for continuous deployment pipelines. It aims to fail builds and deployments fast through practices like contract and integration testing. The pipelines support automation servers like Jenkins and Concourse. Standardizing on tools like Cloud Foundry allows deploying applications using the same processes on different platforms. The pipelines are customizable to suit individual needs.
Data driven devops as presented at QCon London 2018
Devops is usually viewed from a traditional perspective of a collaboration of Dev, Ops, and QA, driven by the change in Culture, People, and Process. But how do you know where you stand and where to move? As in almost any field, data and metrics give you the gauges and instruments. In this talk, we’ll talk about the key measurements for the DevOps transformation process and provide you with 3 metrics you can start measuring tomorrow.
What they don't tell you about micro-services
A conference talk I gave at QConNY.
Who could say no to services that were fully testable, easy to scale, easy to re-write, composable, etc. You read a few books about micro-services and now you're hooked. Those blog posts by Martin Fowler made it sound so easy. Adrian Cockcroft’s videos were so convincing. All of the open source tools out there were going to make this a snap. But now you’re six months in and realize that it's not all so easy. We’ll discuss 6 things we wish we had known when we started our journey.
SPOILER ALERT: It is still worth it.
Topics we’ll cover:
Service Discovery and You
Databases
Testing; how hard can it be?
Dependencies shmependencies
Monitoring? Why would my monitoring be different?
Tools: your current ones have to evolve
Dip into prometheus
This is part one of my Monitoring Distributed Apps series.
Here we explore premises of Distributed Application monitoring focusing on metrics, why do we need them and gradually introducing Prometheus as a solution.

DockerCon EU 2015: Stop Being Lazy and Test Your Software!
Presented by Laura Frank, Engineer, Codeship
Testing software is necessary, no matter the size or status of your company. Introducing Docker to your development workflow can help you write and run your testing frameworks more efficiently, so that you can always deliver your best product to your customers and there are no excuses for not writing tests anymore. You’ll walk away from this talk with practical advice for using Docker to run your test frameworks more efficiently, as well as some solid knowledge of software testing principles.
Performance Tuning in the Trenches
The document discusses the importance of performance testing software systems. It notes that performance testing is a time-consuming process that requires planning infrastructure, building test data scenarios, running performance tests, analyzing results, and evaluating code and architecture. Specific and quantifiable performance metrics are needed to determine if a system passes or fails. The document recommends starting performance testing early in the development process and dedicating adequate time and isolated testing environments for it.

Hand Rolled Applicative User Validation Code Kata
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
