Are you searching for an exciting and competitive career that enables you to experience the full power of DevOps? A site reliability engineer role is a perfect pick for you.

What is site reliability engineering?

Site reliability engineering (SRE) was invented in 2003 at Google, before the DevOps, when a team of software engineers was asked to make Google large-scale sites more efficient, reliable, and scalable. The practices developed by the engineer responded so well that even other big companies, such as Netflix and Amazon, also adopted it and brought innovative practices to the table.

With time and innovation, SRE became a full-grown IT domain, aimed to develop automatic solutions for operational aspects including performance, call monitoring, capacity planning, and disaster response. The software beautifully complements other core DevOps practices, such as infrastructure automation and continuous delivery.

The enlisted below are some typical responsibilities of site reliability engineer:

  1. Proactively supervise and evaluate application performance
  2. Handle emergency as well as on-call support
  3. Make sure software has high-quality logging and diagnostics
  4. Create and sustain operational run books
  5. Support triage raised support tickets
  6. Work on feature defects, requests, and other development errands
  7. Add to overall result roadmap

What does a site reliability engineer do?

How do SREs maintain the error budget and have a consistent system? To answer this question, let us talk about the four core SRE principles, which are implemented by engineers daily.

1. Ensuring an engineering focus

SREs purposely invest a certain amount of time on dropping down human labor, creating an unblemished culture, and sharing knowledge among teams. Keeping track of system consistency. Reporting software is crucial for knowing what is happening inside the systems error. Engineers design the software, which automatically performs routine tasks outcome a self-healing system. Humans will be informed when decision criteria are required.

2. Bringing the system back online

How the team reacts to emergencies is what allows them to keep an eye on the error budget when something goes incorrect. Software engineering always tends to reduce the human factor and helps to ease the pain of fading by recovering quickly.

3. Maintain compliance with change management

When eliminating the human factor from the software, change management requires automation. By leaving a trail, this increases the confidence of the company as well increases the deploy and release rapidity by minimizing the time required in decision making.

4. Forecasting and provisioning the capacity of the system

SRE teams will offer the ability when it’s required and optimize the resources when they are not needed. Ensure the capacity required by the system which is vital to maintain the system’s availability.

Where does SRE fit on your team?

Site reliability engineering roles and responsibilities are vital for the continuous improvement of processes people and technology within any firm. Whether your team has already taken on a full-scale DevOps culture or you are still trying to make the transition, SRE offers plenty of benefits to reliability and speed. SRE is perfect for crossroads of Information Technology(IT) operations, assistance, and software engineering. SRE serves as the perfect combination of skills to strengthen the relationship between developers and IT – leading to better collaboration, shorter feedback loops, and more consistent software.

As we discussed above, SREs invest most of the time on technical and process-oriented responsibilities. They do more than a system administration team or an operation. They utilize their engineering skills to automate and lessen the manual interference essential for administration tasks.

Additionally, they work with other expert teams to offer an incident response, proper monitoring, and management. Over time, these functions advance the constancy and maintenance costs of your dispersed systems.

And finally, they spread the culture of site reliability engineering through your organization so that all teams learn to make decisions with reliability in mind.
