What is SRE in technology? Software reliability engineering (SRE) is an approach to the design, development, and operation of software systems that focuses on operations or ensuring that the system operates correctly and provides high availability to users. SRE differs from traditional software engineering because it emphasizes operations first and foremost, instead of just focusing on development and design…


What is site reliability engineering?

Site reliability engineering (SRE) in technology is a fairly new discipline that has emerged over the last decade. It comprises two approaches: technical site reliability engineering, which focuses on providing automated production operations and availability systems to developers and IT businesses, and organizational site reliability engineering, which improves business and company processes by bridging the gap between IT and the rest of the company. SREs aim to keep applications running with an optimal amount of service at an optimal cost. 

Site reliability engineers must have excellent time management skills to coordinate their teams appropriately. They also must be able to troubleshoot any problems that arise quickly before they escalate. And when necessary, they must be able to handle personnel matters and performance evaluations for employees on their team.


Site reliability engineering and DevOps

Site reliability engineering (SRE) is a practice for ensuring the reliability and efficiency of complex systems that must run continuously. An SRE works on monitoring, testing, and optimizing infrastructure performance to meet service-level requirements with minimal downtime. SREs may also be called DevOps engineers because they need Dev and Ops skillsets to carry out their tasks successfully. 

Site reliability engineering differs from software development: while developing code, some errors are okay (or even desirable) as they can provide valuable feedback on bugs that need fixing; site reliability engineering aims for high uptime. However, there are still a lot of risks when developing new code – there’s often no way to test it other than launching it into production.


The history of SRE

SysAdmins are those who build and maintain the most critical IT services. Essentially, SysAdmins serve as the backbone of IT departments. They are responsible for implementing software patches and security updates, configuring computer networks, troubleshooting, and performing other routine administrative tasks. As a result, technicians must have a high degree of knowledge of different technologies, such as programming languages and networking infrastructure. This is because they’re responsible for handling many different products. The word SysAdmin derives from System Administrator, which was shortened to SysAdmin due to a lack of keyboarding space on minicomputers.

The responsibility to handle systems administration duties has been growing with the rise of the Internet. Whereas reliance on technology for daily life increases exponentially yearly.


How the SRE works at a startup?

I was asked to take on a startup’s challenging and intimidating position of SRE (Site Reliability Engineer). 

I looked up the job title on Google and found that it’s not something you typically see at startups. For one, there aren’t many SREs, especially at small startups like ours. To my knowledge, I’m one of just three people hired as an SRE within my company which also happens to be an enterprise-level firm that services tens of thousands of customers. 

That discovery piqued my curiosity, so I continued looking into what SREs do.


Hiring SREs

Software Engineering means different things to different people. Some might call it Software Engineering; others might call it Software Development or Software Quality Assurance. Regardless of the differences in terminology, all three are subsets of a larger field: software engineering. Often when talking about what a Software Engineer does, it boils down to using or developing specific tools for solving problems and maintaining them. Whether that’s via fixing bugs, developing new features, improving code quality, etc. For example, one type of Software Engineer can be called an SRE, with responsibilities and a focus on reliability-related aspects like fault tolerance and availability.


Site reliability engineering skills

SRE (Site Reliability Engineering) skills are becoming more important as companies need to rethink their entire approach to software architecture. They’re transitioning from a traditional software engineering model of scalable systems with occasional outages to one where reliability is expected. Engineers who specialize in SRE are increasingly needed as senior leadership recognizes the importance of this discipline. In addition, companies like Facebook, Google, Microsoft, and Netflix have made it clear that they don’t want just anyone handling their 24x7x365 reliability needs. So, they want those responsibilities handed off to people with the most expertise in making systems bulletproof! To qualify for a job as an SRE engineer, you’ll need more than just knowledge about distributed systems. Plenty of programming experience is also required for systems management and monitoring.
