What is SRE?

Site Reliability Engineering (SRE) is the process of continuously testing the ‘reliability’ of a new product in development. This enables developers to better understand and adapt to the needs of operations teams.

How does SRE work?

There are several elements to SRE, including:

A ‘Service Level Agreement (SLA)’ is outlined to define reliable has to be for end-users
An ‘Error Budget’ is established to show how much can be spent on fixing errors before production must stop
Site reliability engineers make themselves available to help with development team workloads and vice versa
Site reliability engineers actively find and repair problems during the development stage
Developers take on Operations tasks if necessary
Site reliability engineers create automation wherever possible for the sake of efficiency and reliability

What is a site reliability engineer?

A ‘site reliability engineer’ is an automation/ coding specialist whose job it is to find and solve problems within Development and Operations.

How can SRE benefit businesses?

An SRE team can not only make a DevOps pipeline more reliable, but also far more efficient and scalable. It can also free Development and Operations team members to focus on improving services elsewhere, boosting the quality of releases. Incorporating SRE will also further improve existing DevOps cultures by encouraging greater communication, clarity, and understanding between teams.

Finally, site reliability engineers are specialists in considering and conveying concerns in relation to the wider organization and can extract metrics that can prove extremely valuable for other departments.

Does SRE complement DevOps?

DevOps and SRE work extremely well together. This is largely because both are designed with automation, inter-team collaboration, and communication in mind, as well as boosting efficiency and reliability within IT pipelines. The SRE Foundation qualification even comes from the DevOps Institute.

What do I need to study site reliability engineering?

There are no prerequisites for taking this course. However, it can be helpful to have pre-existing knowledge of SRE, as well as DevOps.

Why is SRE necessary?

SRE was originally developed by Google. Its purpose is to quantify the relationship between Development and Operations teams, ensuring that code is created efficiently, reliably, and with operational factors in mind. This is particularly valuable in organizations where IT departments and teams have become siloed from one another.

Who can benefit from studying SRE?

SRE is ideal for organizations that rely on developing and releasing code. It works particularly well in DevOps environments and is a popular choice with DevOps engineers and DevOps Leaders. Given the growing popularity of SRE, a qualified and experienced practitioner will often find it easier to take the next step in their career.
