What Does the Term Site Reliability Engineering (Sre) Mean to You

A site reliability engineer (SRE) creates a bridge betwixt development and Information technology operations by taking on the tasks typically done past operations. Instead, such tasks are given to these types of engineers who use automation tools to solve problems by creating scalable and reliable software systems.

Standardization and automation are at the heart of what an SRE does, especially as systems drift to the cloud. Thus, they oft have a background in software or organisation engineering or system assistants with It operations experience.

What is site reliability engineering?

We will start with a definition of what this type of engineering is before we movement onto the role and responsibilities of a site reliability engineer.

Site reliability engineering is a term that was offset coined past Google, where it is described as "when you treat operations equally if information technology's a software problem."

The primary purpose of SRE is developing software systems and automated solutions for operational aspects. Thus, SRE does the work traditionally washed by operations but instead using engineers with software expertise to solve complex problems.

Therefore, site reliability engineering can exist considered a fix of practices that incorporates aspects of software engineering science into operations thereby increasing the efficiency and reliability of software systems and improving workflow.

SRE and DevOps

Site reliability engineering is closely related to DevOps, another concept that links software evolution and operations, and can be seen every bit a generalization of core SRE principles. Consequently, SRE plays a large office in successfully implementing DevOps practices.

Additionally, both DevOps and SRE seek to bridge the gap between operations and development teams to evangelize software faster.

However, an article by Google makes a distinction betwixt the 2 terms stating that SRE "happens to embody the philosophies of DevOps, just has a much more than prescriptive manner of measuring and achieving reliability through engineering science and operations work. In other words, SRE prescribes how to succeed in the various DevOps areas."

What does a site reliability engineer exercise?

A site reliability engineer (SRE) works between development and operations. The SRE, then, is a software developer with experience in and knowledge of Information technology operations.

A lot of this role revolves around writing and developing code to automate processes, such as analyzing logs, testing production environments and responding to whatever issues, so this engineer volition be an proficient in writing code.

Such automation allows developers, in plow, to focus exclusively on feature development enabling them to bring new features to production as quickly as possible.

The operations squad, for their part, will detect their workload decreasing equally a SRE volition automate solutions for any recurring problem.

Thus, he/she will be shifting between development and operations work and maintain a balance between them.

Considering an SRE engineer'due south chief focus is on automation, this means that he/she enhances operation, efficiency and monitoring of software development processes.

Required skill prepare

SREs dedicate their time to creating software that volition meliorate the reliability of systems, fixing problems and responding to incidents and issues. As such, they will need various technical skills.

They will need to accept knowledge of various automation tools as they are usually responsible for edifice and integrating software tools to heighten an organizational organisation's reliability and scalability.

Info

As mentioned to a higher place, the SRE will require noesis of coding and nearly of the common programming languages including Ruby, Javascript and PHP.

He/she will as well need to have expertise in the major cloud providers such equally AWS and Google Cloud.

Daily roles and responsibilities of an SRE

Automation

Equally mentioned previously, SRE engineers build tools for automation to manage IT operations. Thus, instead of manually performing these functions, their aim is to automate them. Such functions include:

• Continuous integration and continuous delivery
• Monitoring
• Incident response
• Alerts

Monitoring

SRE engineers are responsible for ensuring that the underlying infrastructure is running smoothly and that systems and tools are working as expected.

They likewise monitor disquisitional applications and services to minimize downtime and ensure their availability.

Upshot resolution

These engineers work closely with developers, peculiarly when problems ascend so they will interact with developers to assistance with troubleshooting and provide consultation when alerts are issued.

This engineer will investigate and so resolve the outcome in the effect that a developer runs into a problem.

Following the incident resolution, the engineer will revisit the issue and make up one's mind the cause to ensure it doesn't happen over again.

Cross team collaboration

Based on the to a higher place, SREs work across different teams, mainly operations and evolution. By building reliable systems and providing support to these teams, this volition give these teams more than time to divert their attention to building new features and hence get these out faster to customers.

Common tools used past SREs

• Monitoring: such tools include AWS CloudWatch and NewRelic
• Incident direction/on-call: such as PagerDuty and VictorOps
• Projection management and effect tracking: such every bit Jira and Trello
• Infrastructure orchestration: including Terraform and SaltStack

To observe out more tools from project management tools to infrastructure and container orchestration used past site reliability engineers, check out this curated list of SRE tools.

How much does an SRE make?

According to payscale, this blazon of engineer makes a bacon anywhere between $76,000 to $158,000 a year in the United States with the average beingness $117,768 per yr.

Conclusion

A site reliability engineer is becoming an increasingly of import function within organizations. Information technology is a challenging part that requires a passion for coding and automation.

Having such engineers in your organisation volition help reduce your operational costs while improving the reliability of your systems.
