With DevOps becoming an integral part of the team, site reliability engineer responsibilities and roles are talks of the town. In recent times we have seen growth in the use of DevOps. This growth was much needed in IT operations as well as software development. With various processes involved in software development like the deployment, configuration, and other tasks, the automation of these processes using DevOps has impacted the industry, and now better results are coming. Keeping this point of view in mind, DevOps has helped the team to develop various systems but the place where it lacks is the system performance and its reliability. There is no one in the team who is fully dedicated to this task and this is where the need for SRE arises. So today on this page, you are going to learn all about one of the important terms in the team and know about the Site Reliability Engineer roles and responsibilities. Furthermore, at the end of this article, we will tell you the best place where you can learn DevOps online and make the best career in this field.

What is SRE?

There are various processes in the team like- change management, software, and system management, incident management, and other IT obstacles. Therefore, SRE is the discipline in which these processes and the various aspects of IT obstacles are being handled with the amalgamation of software engineering and automation.  It will help the team to manage the operation as well as the infrastructure issues. The team will be responsible for making sure that there is productivity, efficiency, fluency, monitoring, and proper management of the services that are offered by the team.

The SRE team is the team of software engineers who are responsible for increasing the reliability of their system. They are engaged in the software development and implementation of those changes so that maximum efficiency can be attained using those services. As we are aware of the fact that the teams are adopting the DevOps culture in their team, they need someone to cover the gap between the development of the software in the team and the IT operations. This gap is filled by SRE. Now that we have an enhanced knowledge about what is SRE, we will now see why we need SRE in the team:

Need for SRE in the Team:

We have seen why SREs are becoming an integral part of the team. In this section, we are going to learn how this is beneficial for the team and the process of software development.

Success of DevOps

As mentioned above, the gap needs to be filled with the development of the software and the IT operations team. If this gap is not filled then there could be friction as developers would want to roll new features and software and the IT operations team will be hesitant for the same. So to manage this, SRE can come in-between and the balance can be restored until those features and software are ready to be rolled out in production.

Covering bottlenecks

There are many times the incidents are coming from the issues that may arise in the production environment. The SRE team is very well equipped to handle incident management and any on-call issues very quickly. Moreover, finding the operational and infrastructure issues can be a high-cost affair for the team, but with an efficient team of SRE, this can be found very easily and can be dealt with on time. This comes under sre roles. They can find the cost of downtime in the team and help the team to quantify the cost of reliability in the processes in the team and its services.

Enhanced reliability

Whatever issues are related to the reliability of the system, it can be managed by an efficient SRE team. Many times, there are reliability issues with the management of databases, infrastructure, platforms, and applications in the team. But with the right implementation of the SRE team, the reliability can be optimized. They are well versed with the best SRE practices which help them to make sure that the application and platforms are reliable from the beginning so that no issue arises later.

Automated operation center

One of the best things about hiring the SRE team in the project is that they use software engineering with DevOps practices and create a system where the incidents can be managed efficiently. They have an automated tool that will help in determining the issues in the reliability and performance of the system and send it to the right person for the job. This will help in reducing the downtime of the system and hence increasing the productivity and performance of the system. You can learn all about this in your DevOps online course.

Roles and Responsibilities of SRE:

Now after having an in-depth understanding of the need for SRE in the team, we will focus on the roles and responsibilities that they have to play in the team. This will give you an idea of what is expected from them and if you wish to have a career in this, then you are fully aware of all of these.

Developing software for better management

When SRE is hired in the team, they are responsible to add more reliability to the existing systems and services. So they can build the software that not only will help the IT processes management but also help the support team. They can bridge the gap between the development of the features and the support of those features. They can make changes in the code or build a new one to make sure that reliability is there and better incident management can be achieved.

On-call responsibilities

There are many times there are issues that arise and an on-call decision needs to be made. This comes under the job profile on SRE. They can help the team to come up with a better process of making sure that on-call requests are managed efficiently without taking a hit at the reliability of the system. They can have an automated system for the monitoring and alerts for the same so that these processes can be managed effectively. This way, the on-call incident management can be optimized with the team of a dedicated team and automated tools and software.


When the SRE team is present in the team from the beginning, they have historical knowledge about various things that are going on in the project. They are part of the teams where the development, deployment, management of issues, and other tasks are being taken care of. Therefore, they are responsible for the documentation of all that knowledge. This helps the teams to have solid documentation of the things that have happened and currently going on in the team. This seamless flow of information comes in very handy for the team to work smoothly and acquire knowledge.

Work on escalation issues

When critical issues arise in production, it is the job of SRE to resolve that and give time to make sure they do not arise again in the future. With time, it is seen that the system becomes more and more reliable and all the escalations are fixed. As they are the storehouse of the information regarding the process and system in the team, they are responsible to direct the issue to the right person so that quick action can be taken and the downtime can be reduced for the system.

Review and optimize the cycle

If the engineers are not reviewing the incidents and the issues coming, they won’t be able to know about the cause and the ways to prevent that to happen in the future. So it is the responsibility of SRE to review what issues are coming in the IT process as well as the infrastructure and operations. This way, they can come up with a plan to optimize the reliability of the process and make sure that the actions are taken to overcome that issue in the future.
