So, last Friday night, I decided to turn my infrastructure into code by learning Ansible, and capture the entire demo configuration.
Monitoring Your Data Center Like a Google SRE
Back in the early ’00s, when Google was beginning to expand its portfolio of services beyond search, it encountered a combination of challenges. Some of these emerged from familiar, classic disconnects between developers and operations folks or between IT services and line-of-business owners. Others were brand new, never-before-seen failure modes that arose from providing services on novel cloud platforms—and doing so at planetary scales.
To confront these challenges, Google began evolving a discipline called Site Reliability Engineering (SRE), about which the company published a very useful and fascinating book in 2016. SRE and DevOps (at least the contemporary version of DevOps that’s expanded into a vision for how IT operations should work in the era of cloud) share a lot of conceptual and an increasing amount of practical DNA; particularly true since cloud software and tooling have now evolved to enable ambitious folks to begin emulating parts of Google’s infrastructure using open source software such as Kubernetes. Google has used the statement, “Class SRE implements DevOps” to title a new (and growing) video playlist by Liz Fong-Jones and Seth Vargo of Google Cloud Platform, showing how and where these disciplines connect and nudging DevOps to consider some key SRE insights.
