Site reliability engineering (SRE) makes use of software engineering to automate IT operations tasks like production system management, change management, incident response, and emergency response that systems administrators (sysadmins) would otherwise handle manually. Read on to learn more about the job description, role, salary, and certification of a site reliability engineer.
The underlying idea of SRE is that automating oversight of massive software systems using software code is a more scalable and long-term solution than manual intervention, especially if such systems grow or move to the cloud.
SRE can also significantly lessen or eliminate the conflict that naturally arises between development teams, who want to continuously release new or updated software into production, and operations teams, who don’t want to release any new software or updates unless they are certain they won’t cause outages or other operational issues. As a result, even if SRE isn’t necessary for DevOps, it closely adheres to the concepts of DevOps and can help DevOps succeed.
Ben Treynor Sloss, vice president of engineering at Google, is credited with developing the idea of SRE. He is known for saying that “SRE is what happens when you ask a software engineer to design an operations team.”
Site Reliability Engineer
A site reliability engineer is a software developer with knowledge of IT operations—someone who can code and who also knows how to ‘keep the lights on’ in a big IT system.
Site reliability engineers spend the majority of their time creating code that automates manual IT operations and system administration tasks, such as analyzing logs, performing performance tuning, applying patches, testing production environments, responding to incidents, and conducting postmortems. Over time, they hope to spend a lot more time on the latter and a lot less time on the former.
At a higher level, the SRE team acts as a link between the development and operations teams, allowing the development team to release new software or new features as quickly as possible while also ensuring an agreed-upon acceptable level of IT operations performance and error risk under the service level agreements (SLAs) the company has with its clients. The SRE team assists the development and operations teams in establishing operations standards based on their expertise and a wealth of operations data.
Service level indicators (SLIs)
Systems’ service levels are measured using measures like availability (uptime) and latency.
SLOs, or service level objectives
Indicators for measuring service levels that have been agreed upon include:
Mistaken budgets
For the longest period, a system can malfunction or perform below expectations without breaching the SLA’s contractual obligations. The site reliability engineering team employs the error budget, which is more than just a metric, to automatically balance a company’s rate of innovation with the reliability of its services.
Site Reliability Engineer Job Description
The site reliability engineer job description frequently encourages applications from people with a variety of backgrounds, such as software engineers with operations experience, system administrators with programming expertise, IT operations specialists with coding experience, system architects, and production automation managers.
Monitoring, automating, and enhancing the performance, availability, and reliability of software systems inside an organization are the duties of an SRE. They are tasked with preventing problems, managing infrastructure, developing efficient monitoring methods, and making sure computer systems run without hiccups.
How to write a site reliability engineer job description
It is simpler to construct the job description of a site reliability engineer once the general responsibilities and competencies of the function have been identified.
It would help if you concentrated on communicating the critical elements of the position, such as:
- Rotation of on-call personnel for proactive incident response
- Create action logs after occurrences so that automated solutions can be developed for incident response.
- SRE tools are used to monitor infrastructure, and tools are recommended as needed.
- Create mechanisms for incident response and monitoring alarms.
- Enhance teamwork and operational procedures
- CI/CD pipeline infrastructure automation through coding
- Maintain reliability by planning, constructing, and updating the fundamental infrastructure as the solution scales.
- Strong programming abilities and in-depth system understanding should be displayed.
- Make cultural changes to lay the groundwork for process reforms.
The technical requirements of the position must be balanced with the soft abilities needed to succeed in the position, as described in the job description.
Site Reliability Engineer Role
It is significant to note that the role of a site reliability engineer rarely calls for freshmen and that some practical experience is required. The position necessitates a strategic and practical comprehension of numerous distinct functions, which cannot be achieved through purely academic learning.
A site reliability engineer’s job role will mention the following tasks and responsibilities:
#1. Software development expertise
Traditional IT and product site managers, who depend on manual and iterative procedures, have a more sustainable and intelligent replacement in SREs. They need to create useful and specifically designed software to enhance the current system. For instance, a site reliability engineer may be charged with building from scratch a platform for automated warnings on wearables. After all, operations are a software problem—a basic principle in site reliability engineering. Because of this, SREs need to be knowledgeable about software development and comfortable with popular scripting languages.
#2. Ability to support incident escalation and troubleshooting
Automation or a human help desk with basic skills is typically able to handle IT infrastructure incidents at level one. Site reliability engineering teams must be ready for escalations and more difficult troubleshooting because not all problems can be fixed promptly. When level one and level two interventions fail to resolve a production environment issue, an incident escalates. SREs enter at a higher level so they can implement cutting-edge solutions to pressing problems. To avoid similar escalations in the future, they must also record the occurrence and create automated responses.
#3. The recording of procedures and information
Cross-functional experts from a variety of departments, including software development, IT operations, service help desk level one and level two support, etc., will frequently collaborate with site reliability engineers. This means that over time, individuals develop a significant body of information that is frequently undocumented. Without documentation, departments continue to operate in silos, and only certain people are qualified to perform certain jobs. The duty of creating internal documentation, playbooks, and other centralized knowledge repositories that can aid current teams and upcoming hired resources has been given to SREs as a result.
#4. Evaluation of incidents after resolution
A “postmortem culture” is one of the key principles of a site reliability engineer. This implies that an issue or incident is not automatically closed after it has been resolved. Instead, SREs look into the details and circumstances that led up to an incident without assigning blame to improve the infrastructure going forward and avoid outages brought on by the root cause. A well-written post-mortem document that includes the important details is necessary for conducting post-mortem reviews. Time and dates, names of stakeholders, impact on users and revenues, root causes, lessons learned, and action points will all be included in the paper.
#5. Load management
The processes and methods used to balance the supply of data center resources with traffic and service demand are referred to as load management. Various circumstances, such as a spike in demand brought on by unexpected market trends or physical accidents, may cause service availability to be interrupted at any time. While understanding that 100% uptime is never physically attainable, site reliability experts strive to ensure as much service availability as they can. They must use strategies that will step in if an automatic solution fails, such as kill switches and manual overrides. SREs are often in charge of a three-part load management system that includes load balancing, load shedding, and auto-scaling.
#6. Knowledge of data processing systems
To meet the three needs of high-volume traffic and high-bandwidth services, efficient data processing pipelines are essential. A contemporary business will use data from numerous sources, including big data. To power application features or guide decision-making, site reliability engineers must create data processing pipelines that transform these fragmented and unordered datasets into organized information. Usage problems can result from delays or defects in the pipeline and take a lot of time and work to fix. The responsibility of an SRE is to reduce these risks and provide the highest level of service availability for applications that rely on data processing pipelines.
#7. Configuration design expertise
Software systems must be properly set up regularly because they are not rigid and constantly change to meet traffic and business needs. Configuration management for software products, datasets, and the production systems that run services is a part of the SRE job position. Two elements must be given top priority in configuration design: simplicity for future SRE teams to adjust the system with the least amount of work and reliability for users to enjoy high availability and uninterrupted application services. Site reliability engineers can create tools to help with configuration creation and management in this situation.
#8. Capacity to rebalance workloads
Each engineer on an SRE team has precisely the right amount of work to utilize their skills and abilities. No one is therefore overburdened. However, a task imbalance might result from changes in resources, vacations, and other interruptions. As SREs manage the business-critical infrastructure that cannot tolerate even a day of interruption, this is a serious challenge. Engineers often overextend themselves, become distracted by menial chores, and spend less time on development that adds value when there is a labor shortage. To manage workloads, they must be able to restructure teams, make tool adjustments, or do both at once.
