Building a system to be resilient is the highest leverage step in ensuring high uptime and low MTTR (mean time to repair).
(upbeat electronic music)…- All right, when you start talking about operations,…people immediately envision the activities…that happen in production, but most of your success…in production is based on decisions you make…way at the front of the pipeline.…In this section, we'll talk about how you design…your application to make it work great,…even in adverse conditions.…First, we'll address the software architecture side.…Software engineering has developed a bunch…of design patterns over time like those…in the popular Gang of Four "Design Patterns" book.…

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.
