Hello everyone, welcome back, with this post I plan to share my perspective about SRE( Site Reliability Engineering). I was impressed by the perspective of harnessing the power of automation to support services in a production environment.
While DevOps (along with all the tools) is changing the way(mindset, culture & style) products are developed and enabled in production, SRE is one of the major pillars (other two, Continuous Delivery and Infrastructure Automation) of the DevOps transformational journey.
Key callouts:
1. SRE = Site(Service) Reliability Engineering
Almost all organizations( even hardcore product companies) want to provide their offering as a service(XaaS, Anything as a service). Service offerings help to flatten the revenue curve making it more predictable and it is a welcome change for the consumers since they don't have to plan for steep (and uneven) CAPEX allocations for greenfield deployments or network refresh.
2. Process workflow as Code
This perspective fascinated me, while there is a lot of focus within engineering teams to automate (the results are visible as well) automating production service support is a well-deserved extension to the "Automate Everything" philosophy.
And why not? most of the processes have well-defined workflows and are repeated over and over again.
3. Mindset and Skillset :
SRE thinking forces solving the same problem, but with an engineering mindset. SRE team is a group of software engineers and system engineers building and maintaining operational processes "as code".
Self-service automation can reduce the manual dependency among team members and make the entire process more efficient by reducing manual mistakes and uplifting the operational code based on retrospective learnings and modifications for new business needs.
4. Engineer's quality of life:
All of us are aware of how tough is to maintain high-reliability business-critical services. My sincere regards to all the folks who spend the sleepless nights and sacrifice family time for the wider good.
SRE thinking aims to automate everything that is possible to automate and enable humans to do more thinking( feedbacks) than doing.
People are our greatest asset and any change that promises an improvement in their quality of life is welcome.
I will share additional insights from SRE by Google and another book by Richard cook, "How complex systems fail"
Feel free to share your insights, resources, and any feedback.
Have a great day!
