DevOps and Cloud Native
The document discusses the evolution of web technology and infrastructure, highlighting the exponential growth of data from 1999 to 2020, the transition to microservices, and the adoption of tools like Docker and Kubernetes for container management and orchestration. It emphasizes continuous delivery and the impact of DevOps on reducing development costs and increasing deployment frequency, alongside examples from a global financial services group. The text also contrasts traditional development methodologies with modern practices, showcasing the benefits of automation and collaborative culture in software development.

We no longer have a complex set of provisioning scripts or AMIs— we just hand the production cluster an image, and it runs. There’s no more stateful instances, and we’re guaranteed to run the same exact code on both staging and prod.” http://highscalability.com/blog/2015/10/19/segment-rebuilding- our-infrastructure-with-docker-ecs-and-te.html DEVCON 2015 TECH RADAR

- 76. PUSHING IN MULTIPLEPHASES • latest - a version of the site running the latest code at all time. Employees would use this site and find any major bugs almost instantly. • p1 - a handful of servers that would be the first to run the new code in production. The goal of this was to catch any obvious fatals/warnings in the logs before a new release would gain wide distribution. • p2 - a larger set of servers on the web tier. The number of servers in p2 increased over time, but I believe hovered around 5% or so. This offered several opportunities, including catching long tail fatals and monitoring resource use along with key user metrics on the servers for any anomalies. • p3 - the entire web tier.
