Continuous delivery best practices with a Case Study of a technology-driven media company
“Continuous Delivery (CD) is a software engineering approach in which teams keep producing valuable software in short cycles and ensure that the software can be reliably released at any time.” - Wikipedia

Continuous delivery best practices with a Case Study of a technology-driven media company
Starting point
• Multiple independent products & teams • Varying level of build automation • No configuration management tools • Traditional “in-house” hosting, DIY-mentality
Then IT was out-sourced …

Build Automation is a must!

Use SaaS vs. re-invent your own if “vendor lock” becomes a problem solve it later

Infrastructure as a Code

What goes into Cloudformation stack? (and what is left outside of it)
Continuous delivery best practices with a Case Study of a technology-driven media company
Statefull, Slow to deploy, Shared resources …
Stateless, Fast to deploy, Utilized inside single stack …

Who/What does configure your instances? (and how it knows about the infrastructure)
Continuous delivery best practices with a Case Study of a technology-driven media company
• Auto scaling & launch configuration • AMI vs. Install • Parameters from cloudformation stack
to Chef via instance metadata. • Cookbooks for common build formats. • Cfn-hup will trigger re-config for
changes.

“Thanks to new deployment process we can deploy builds into production in the middle of the day and have to sweat if it is going to work” - Lead developer of the busiest website in Finland

“But rebuilds are taking too long! We need to build every commit and deploy every build!” - Anonymous developer

Cloudformation Production vs. Development & Testing • Use same template for all
environments! • Customize with
• Parameters • Mappings • Conditions
• Allow code deployment to development using stack updates to avoid re-builds.
• Enable/disable features by stack update.

“TODO” … improvements and new features • Individual teams should be self sufficient
while maintaining centralized “sanity checks”. • Create AWS account for each search/product.
Connect via central account using VPC peering. • Manage Cloudformation stacks with Service Catalog. • Replace custom code with AWS services;
CodeDeploy, CodeCommit & CodePipeline
