How to Become a Site Reliability Engineer: Job Description, Roles & Responsibilities

Most companies require site reliability engineers to have at least a bachelor’s degree in computer science or a related field. SRE responsibilities closely align with those of DevOps – they both deal with automating IT operations but do it from different perspectives. While DevOps engineers are responsible for production environments, SREs focus on the whole infrastructure, its reliability and performance at scale.

Platforms like Docker, Kubernetes, and Nomad are some of the leading solutions for supporting modern applications in the ever-growing cloud native environments. Python is one of the most common and popular programming languages out there. It is a general-purpose language, meaning that it has a wide-range of https://wizardsdev.com/en/vacancy/sre-site-reliability-engineer/ uses, such as the backbone of websites or web applications, automating tasks, or even testing. In fact, it is used by companies like Netflix, Venmo, and Dropbox, just to name a few. Python is easy to learn, so it is good for someone just starting out, but versatile and extensive for Python experts as well.

A DevOps approach

The amount of time, resources, and effort it takes to build software is significant, so if your services are down, you are losing hundreds of thousands of dollars per minute. This trend is observed across outages, whether enterprise software and data centers experience them or consumer applications. In addition to losing money, companies are also faced with losses in employee morale. Site reliability engineers will regularly work with cross-functional professionals from various teams such as software development, IT operations, service help desk level one and level two support, etc. This means they accrue a sizable body of knowledge over time, which is often not documented.

• To improve the existing system, they need to develop valuable and purpose-built software.
• This indicates that we are going to expect an outage at some point.
• Measure the risk of introduced features to plan ahead and improve the infrastructure.
• “One of the main things that DevOps tries strive to solve is … cross-functional teams,” Ortigoza said.
• Regardless of whether you have a dedicated SRE team, you can’t go wrong with driving SRE principles across the board.
• Other programming languages like HTML , JavaScript, and CSS do not include aspects of both front-end and back-end services, which is what sets Ruby on Rails apart from other languages.

SRE is an advanced form of infrastructure management, so using DevOps best practices is the most reliable way to build resource-efficient workflows and processes. A Site Reliability Engineer is a person who works to ensure that the systems and infrastructure of a company or organization are running smoothly and that they can handle any unexpected problems that might arise. They work to prevent outages and downtime, and when problems do occur, they are the ones who fix them as quickly as possible. Please note that the salaries and hourly rates mentioned in this article don’t equal the cost of hiring offshore software developers through outsourcing companies.

Knowing how distributed computing works and understanding the concept of microservices are both significant advantages for an SRE.

What Skills Are Needed to Be a Site Reliability Engineer?

Now that you know more about the overall responsibilities and duties of an SRE, let’s get into specific skills. The industry needed people who could increase the reliability and performance of this system. Benjamin Treynor introduced the concept of the site reliability engineer back in 2002. Generally speaking, it takes about 2-3 years to become a site reliability engineer. Of course, this depends on a number of factors, such as your prior experience, whether you have a related degree, and how quickly you learn new things.

The lengthy hiring process, salaries, and retaining of SREs will cost you a fortune. Building an in-house team requires time to find the right specialists. SREs dramatically reduce the risk of downtimes and outages, and if you run a real-time system, you know how costly these can be. One of the most expensive downtime cases so far belongs to AWS.

However, SRE can now automate the design process and determine whether the service adheres to SLA. Site reliability engineering is a DevOps practice wherein IT professionals codify and automate infrastructure and application maintenance and support. SRE is primarily concerned with service reliability, and commonly uses service-level agreements to dictate and meet expectations around various metrics like uptime.

Usually, this has to do with alerting on-call and incident management and response, i.e., the actions to be taken after you have the monitoring set in place. It helps them take stock of the situation before thinking about the changes they need to make to the architecture or the team’s workflow. SREs are also tasked with making sure that the software is working as it should, and that it can scale. Scalability is essential to any long-term development project, as it reflects the potential for your software to grow and expand its user base without compromising on service quality.

Collaboration points and similarities between SRE and DevOps

SRE promotes a collaborative culture between development and operations teams by breaking down silos and fostering effective communication. SRE practices ensure high availability, reduce downtime, and mitigate the impact of failures by enforcing monitoring, proactive alerting, fault tolerance mechanisms, and disaster recovery strategies. Improve communication between development and operations teams.

Because if yes, you’ll need to hire more SREs to cover knowledge gaps. One of the key roles of SREs is to minimize or avoid downtimes of your services. According to Statista, 25% of enterprises worldwide report that an hour of downtime costs them between $301,000-$400,000. For more than a third of small and medium businesses, downtimes cause customer loss, and for 17%, they lead to revenue loss. As long as the product runs within this budget, developers feel free to update the product or modernize its functionality.

SRE vs. DevOps: What’s The Difference?

If you don’t want the hassle of managing your own team, outsourcing can be a smart option. You’ll need to find a reputable vendor, but once that’s done, you’ll be paying only for the service itself. Thus said, partnering with MSPs like Relevant Software is a win-win decision for all, allowing SRE talents to have a variety of projects and startups. Companies, in turn, can gain access to SRE expertise they wouldn’t be able to hire otherwise.

The SRE team automates deployment, scaling, monitoring and related tasks across these environments. Explore job listings that interest you and compare them to the skills you already have. Then, focus on the next key skill you can develop to get closer to meeting the most important prerequisites. In addition to specific skills, some companies may require experience in certain areas, while others may provide training to fill any knowledge gaps and help you get to the necessary level. In future articles, I will look at other categories of best practices for SRE,the technologies involved, and the processes to support those technologies.
