THE INDUSTRY
SRE and DevOps are principles designed to break down silos and foster a culture of collaboration with the goal to create scalable and highly reliable software systems
DevOps culture embraces the principles, practices, and mindset required to ensure open communication & collaboration within engineering teams. It has sprung from the need to break down silos between Development & Operations to ensure that infrastructure can be faster; better; more agile.
By implementing a mindset of open communication & enacting processes that embody this mindset, DevOps/SRE teams can experience the joys of a well-oiled machine & agile infrastructure.
The State of DevOps
DevOps practices have evolved in recent years in many organizations seeking to respond more effectively to their business challenges. While DevOps previously focused primarily on IT services, it now extends across the entire enterprise, impacting processes and data flows, driving deep organizational changes.

Site Reliability Engineering
Reliability Engineering was coined by Google in 2003 and involves running a company’s ‘site’ smoothly, efficiently and reliably.
Over time, this has evolved to ensuring reliability of a company’s entire systems & infrastructure.

DevOps Engineering
DevOps Engineering was coined by Patrick Dubois & Andrew Shafer in 2009. It involves balancing & blending the disciplines mentioned here. It is not simply ‘Development’ and ‘Operations’ married together, instead requiring teams to eliminate all silos, improve communication across all departments & truly embody agility within an engineering department.

Observability Engineering
Observability Engineering has grown out of Reliability Engineering into its own discipline and goes deeper than simply monitoring what you already know. Critically it requires you to monitor & measure what you do not know yet & observe all possible areas of a company’s infrastructure in deep detail.

Cloud Engineering
Cloud Engineering can involve working on a variety of the above disciplines, but critically requires operating with the Cloud, as opposed to on data-centers/bare-metal infrastructure.

DevSecOps
Whilst security engineering has been an ongoing concern for many years, it’s important to note its increasing migration into the world of DevOps. As DevOps/SRE teams have broken down silos; security concerns have perhaps been left under-appreciated. Therefore, in an ever-more digital age it is imperative that companies acknowledge the need to integrate security into their DevOps/SRE ecosystem.

Where to next?
As time moves on, new disciplines come to the fore: There’s always a ‘next big thing’. However, this does not mean previous disciplines are eliminated! Instead, with a true DevOps culture & mindset implemented, the new & old can interact seamlessly in contributing to a truly reliable & agile infrastructure.
