Ben Treynor Sloss, then VP of Engineering at Google, coined the term “Site Reliability Engineering” in 2003. Site Reliability Engineering, or SRE, aims to build and run scalable and highly available systems. The philosophy behind Site Reliability Engineering is that developers should treat errors as opportunities to learn and improve. SRE teams constantly experiment and try new things to enhance their support systems.

SRE is a new field that combines aspects of software engineering and operations. Job openings for Site Reliability Engineers surged by more than 72% in the US in 2019, making it one of the most sought-after roles. SREs provide critical value for an organization’s cyber security policy implementation and upgrades. 

What is Site Reliability Engineering?

Site reliability engineering (SRE) is an area that combines aspects of software engineering and operations. The average cost of a system’s downtime comes to around $5,600 per minute, equivalent to more than $300,000 per hour.

The main goal of SRE is to ensure that a site or service is available and performing well. SREs do so by designing and building systems that are resilient to failure and by monitoring and responding to incidents when they occur.

While this sounds a lot like DevOps – it’s not. The main difference between SRE and DevOps is that SRE places a greater emphasis on reliability and availability, while DevOps focuses on speed and agility. A Site Reliability Engineer’s role is to ensure that systems are reliable and available while providing DevOps-style automation and efficiency.

Some of the specific benefits of SRE include:

  1. Reduced downtime: By designing systems to be resilient to failure and monitoring and responding to incidents quickly, SRE can help reduce the time a site or service is unavailable.
  2. Improved quality: SRE can help improve the overall quality of service by making it more reliable and easier to operate.
  3. Reduced costs: SRE can prevent outages and disruptions and ensure that systems can recover quickly when problems occur.
