Ops has learned hard lessons about resiliency over the years; take it into account when building your applications.
- Last time we talked about the theory of designing…resilient systems, from the development perspective.…Let's bring our hard one operations experience to the table.…You are now about to witness…the strength of street knowledge.…First, the hard truth is that all systems fail.…Code is often written with the assumption that failure…of underlying systems is, if not impossible,…at least very unusual, and should probably have…to result in some manual intervention.…But failure and slow downs are common.…
Pushing more and more money at highly…available systems, is a losing game.…I spent a lot of time in my career listening…to excuses about why that system that doesn't have…any single point of failure still went down.…Don't fall for that trap.…In fact, you can take the opposite approach,…with what we call deliberate adversity.…One of the most celebrated bits of software in DevOps…is another gem from the Netflix crew,…and it's called the Chaos Monkey.…We talked about it in a previous video, but in short,…it monitors the Netflix production environment,…
In this course, well-known DevOps practitioners Ernest Mueller and James Wickett provide an overview of the DevOps movement, focusing on the core value of CAMS (culture, automation, measurement, and sharing). They cover the various methodologies and tools an organization can adopt to transition into DevOps, looking at both agile and lean project management principles and how old-school principles like ITIL, ITSM, and SDLC fit within DevOps.
The course concludes with a discussion of the three main tenants of DevOps—infrastructure automation, continuous delivery, and reliability engineering—as well as some additional resources and a brief look into what the future holds as organizations transition from the cloud to serverless architectures.
