Site reliability engineering (SRE) is a crucial field for companies to maintain infrastructure and workflow efficiency. Additionally, it removes bottlenecks, ensures software reliability, solves complex problems, and bridges the gap between development and operations in a DevOps organization. This guide covers SRE roles, education requirements, and potential salaries.
What Is A Site Reliability Engineer (SRE)?
A site reliability engineer, a subset of a software engineer, is in charge of guaranteeing the performance, scalability, and availability of an application or website. Site reliability engineering has grown into a more vital discipline as consumer demand for superior online experiences rises.
Therefore, businesses can maintain the smooth operation of their applications and websites even in high-traffic environments with the assistance of a site reliability engineer. So what precisely does a site reliability engineer do? Let’s find out in the following section.
What Does A Site Reliability Engineer Do?
A site reliability engineer (SRE), as was previously mentioned, is in charge of making sure a company’s application or website runs efficiently. They work collaboratively with developers to find and address potential issues before users are harmed. Engineers for site reliability also keep an eye on the systems and develop plans for handling emergencies. Many times, they are available around the clock in the event of a crisis.
Additionally, in the interest of ensuring that the site can handle the volume of traffic without experiencing any problems, SREs are frequently involved in capacity planning as well as performance tuning. As a result, SREs are crucial for guaranteeing that a company’s app or website is consistently accessible and effective.
Roles And Responsibilities Of A Site Reliability Engineer (Sre)
Site reliability engineer responsibilities include technical work, such as automating tasks, provisioning servers, troubleshooting outages, and process work, including on-call rotations and incident response.
#1. They build software to help DevOps and support teams:
An SRE’s primary goal is to create software that automates as much labor as possible. Any task that could be done automatically but isn’t because it’s tedious, time-consuming, or involves too much context switching is referred to as a toil.
Additionally, manual incident management tasks, regular maintenance tasks, and capacity planning tasks are a few examples of the tasks of an SRE.
#2. They Fix support escalation issues:
In many cases, an SRE is also in charge of managing support escalations. Find and resolve production-related problems; this calls for working alongside consumers or other teams. Additionally, a problem’s primary cause is frequently discovered in recent changes to the infrastructure or code.
Therefore, in order to efficiently debug production issues, the SRE team must have a comprehensive understanding of both the infrastructure and the codebase.
#3. SRE Optimize on-call rotations and processes:
An effective site reliability engineering team must be available 24/7 to handle production issues. They typically have an on-call rotation, with each member taking turns during off-hours. Additionally, SREs may also optimize the on-call rotation and incident response process by collaborating with other teams to set up alerts in a centralized logging tool for quick detection and resolution of critical errors.
#4. They document “tribal” knowledge:
The site engineer is also in charge of recording indigenous knowledge. The skill that is handed down from one worker to the next is known as tribal knowledge. It contains abilities, methods, and customs that aren’t recorded anywhere but are crucial to the work. Additionally, the site engineer makes sure that tribal knowledge can be transferred to future teams so it can enhance project results by documenting it.
#5. They conduct post-incident reviews:
An SRE’s post-incident reviews (PIRs) are yet another crucial duty. Every significant incident is followed up with a PIR in order to determine what went wrong and how to avoid future occurrences. Additionally, participants in PIRs frequently include any affected customers as well as all team members involved in the incident. A PIR’s objective is to locate systemic problems so that they may be resolved before they lead to further outages.
What Is Required To Become A SRE?
A bachelor’s degree in computer science or a closely related field is typically required by employers. Programming and operating system knowledge are desirable skills to include in your CV.
Additionally, you might complete an internship as you work toward your bachelor’s degree to provide you with experience for a position at the entry level. By participating in boot camps and obtaining certificates connected to SRE work, you can improve your education.
What Skills Are Required For An SRE Engineer?
Let’s take a look at the most important site reliability engineer skills that you need to have in order to fulfill this role.
#1. Coding languages
You must be skilled in at least one coding language to be an SRE. This is due to the fact that writing code is frequently essential in order to automate processes or create tools. For instance, Python, Java, and Go are the most widely used programming languages among SREs.
#2. CI/CD pipeline development
You must be knowledgeable about continuous integration (CI) and continuous delivery (CD) pipelines in order to safely and effectively release code changes.
#3. Mastered distributed computing:
Distributed systems are widely used by businesses today to obtain higher availability and scalability. Therefore, to be able to troubleshoot and improve distributed systems, an SRE must have a thorough understanding of how they operate.
#4. Using Monitoring Tools:
Monitoring is necessary to keep tabs on the condition of a company’s services and goods. You should be comfortable using monitoring tools like Prometheus, Pingdom, and Zoho as an SRE.
#5. Using version control tools:
To exchange and manage code changes, developers use version control tools like Git. To assist developers with code deployments as an SRE, you must be acquainted with these tools.
#6. Understanding operating systems:
You must possess in-depth knowledge of a variety of operating systems, including Linux, Windows, and macOS, in order to manage company services effectively.
#7. Deep understanding of databases:
Databases are frequently used by businesses to store data. Therefore, to successfully troubleshoot whatever issues may arise, an SRE must have a thorough understanding of how various types of databases operate.
#8. Automation skills:
Automation is essential for minimizing the amount of manual labor required to maintain business services. Additionally, you should be knowledgeable about various automation tools like ACCELQ and Avo Assure if you work as an SRE.
#9. Knowledge of cloud-native applications:
Applications that are “cloud-native” were created with the intention of being deployed on cloud infrastructure like AWS and Azure. In order to effectively manage cloud-native applications, an SRE should have prior experience with them.
#10. Clear communication skills:
The capacity for clear and concise communication is among the most crucial abilities for site reliability engineers. This is due to the fact that you will frequently have to inform other team members of critical information regarding system alerts or outages.
#11. Problem-solving skills:
Last but not least, site reliability engineers need to be able to solve issues quickly and effectively. When dealing with unforeseen outages or performance problems, this skill will be useful.
