The role and responsibilities of a site reliability engineer (SRE) may vary depending on the size of the organization, and as such, so do site reliability engineer tools. For the most part, a site reliability engineer is focused on multiple tasks and projects at one time, so for most SREs, the various tools they use reflect their eve-evolving responsibilities.

In the world of a site reliability engineer (SRE), failure is not only an option, but also expected. Systems, web applications, servers, devices, etc., are all prone to performance issues and unexpected outages at some point. It is an unavoidable fact. These unexpected failures can lead to huge revenue losses, customer trust and depending on the industry, maybe fines. Fortunately, SRE incident management is one of the core practices used to limit the disruption caused by unexpected issues.

There was a time when standing up a website or application was simple and straightforward and not the complex networks they are today. Web developers or administrators did not have to worry or even consider the complexity of distributed systems of today. The recipe was straightforward. Do you have a database? Check. Do you have a web server? Check. Great, your system was ready to be deployed.

In one of our previous articles, we discussed what an SRE is, what they do, and some of the common responsibilities that a typical SRE may have, like supporting operations, dealing with trouble tickets and incident response, and general system monitoring and observability. In this article, we will take a deeper dive into the various SRE principles and guidelines that a site reliability engineer practices in their role.

The role and responsibilities of a site reliability engineer (SRE) may vary depending on the size of the organization. For the most part, a site reliability engineer is focused on multiple tasks and projects at one time, so for most SREs, the various tools they use reflect their eve-evolving responsibilities. A typical SRE is busy automating, cleaning up code, upgrading servers, and continually monitoring dashboards for performance, etc., so they are going to see more tools in that toolbelt.

A site reliability engineer, or SRE, is a role that that encompasses aspects of both software engineering and operations/infrastructure. It also encompasses a strategy and set of practices and principles across service offerings and is closely tied to DevOps and operations. The term site reliability engineering first came into existence at Google in 2003 when a site reliability team was created. At that time, the team was made up of software engineers.
