SRE vs DevOps: What is the Difference Between Them?

Software is a major part of our life and the need for advancement in software development is increasing every year, while working at Google, software developer Benjamin Treynorin in 2003 introduced site reliability engineering (SRE), which began to influence the software production mainstream methods. He delegated some ops responsibilities to his software engineering team, inventing the idea of SRE and assisting in the resolution of conflicts between development and operations. 

DevOps can be called the successor of the Agile method as it is based on a similar structure for software delivery. DevOps is a method that ensures synergy between the development team and the operation team. By implementing DevOps the software production time decreases significantly and the frequency of release of updates increases. 

The following topics will be briefly explained in the article:


Principles of SRE & DevOps

Principles of SRE & DevOps

Both SRE and DevOps are guided by a set of principles. Both sets of principles promote convergence towards business goals. Some of their principles are similar between SRE and DevOps. The greatest distinction between SRE and DevOps is that DevOps principles specify outcomes. The SRE principles explain the steps involved in achieving a goal. In this manner, SRE best practices provide a method of putting DevOps ideas into practice.

The formula used to calculate SLI is,

SLI = Good Events * 100 / Valid Events

What is SRE?

What is SRE?

SRE stands for site reliability engineering, and it is a software engineering approach to IT operations. To manage systems, address problems, and automate operational activities, SRE teams incorporate software. 

The tasks which were earlier performed by the operation team mostly manually are now provided to engineers and ops team to use automation to perform those tasks. SRE is a method in which an individual has complete insight from product development to product delivery to monitoring. 

In SRE a team member spends half of his time in resolving issues of the customer and the other half into automating tasks, this process of eliminating toil or reducing manual effort is a key role of an SRE engineer. 

Taking risks is a common philosophy that comes along with SRE, an SRE team takes risks and in the process, they learn about potential damages that a particular risk comes with, an SRE is equipped with the knowledge to gauge a problem and categorize it as a nonsignificant problem or a major problem, therefore taking actions accordingly. 

Extreme reliability comes at a price: enhancing reliability restricts the speed with which new features can be created and product supplied to customers, as well as substantially increasing their cost, limiting the number of features a team can afford to offer.

Minor issues are usually not recognized by customers, which the SRE team accepts because fixing such issues and making the product more dependable always demands substantial money and time investment.

What is DevOps?

DevOps is a process or method of making the developer team and operation team work together. This ensures high productivity and reduces the time of product development.DevOps methods implement automation at every possible step, this increases the product release cycle and makes the process efficient. DevOps shares similarities with Agile software development, and some features of DevOps are derived from the Agile method.

Developers in DevOps work on small pieces of code, resulting in the rapid iteration of the source code and faster product updates.

DevOps method creates a software development pipeline, DevOps pipeline is a set of processes that are implemented using tools by the development and operation team to build, test and deploy software efficiently.

The structure of the DevOps pipeline may vary in different organizations but the most common components of the pipeline are continuous integration, development, monitoring, and feedback.

SRE vs DevOps

SRE focuses on the system engineer position in core infrastructure and is more appropriate in a production setting. DevOps, on the other hand, is a methodology that helps development teams and their non-production computing environments to be more automated and simple.

Some of the key differences are noted below:

DevOps SRE
Reduce organization silos
Accept failure as normal
An interactive and frequent addition to the project
Implement tools and automation
Everything is measured
Ownership is shared with developers by using the same tools and techniques across the stack.
A formula evaluating accidents and failure against new releases.
Lowering the cost of failure to encourage rapid movement
Implementing automation and focusing on areas that bring long-term benefits.
Consider operation is a software problem and defines the prospective measure of availability, uptime, outage toils, etc.

SRE vs DevOps Tools

Common tools used in DevOps and SRE are listed below:


Containers for Microservices and Orchestration Tools


Source Control Tool


Continuous Integration / Continuous Deployment (CI/CD) Tools


Data Storage Tools


Configuration Management Tools


Monitoring Tools

SRE vs DevOps: Which one to choose as a career?

SRE vs DevOps: Carrier choices

DevOps Career Track:

A career as a DevOps engineer is sure to bring you along on an exciting journey, you would constantly be working on new projects and continuously upgrading the software development life cycle. With the rapidly changing software industry, a DevOps engineer has to learn the latest tools and processes.

Positives of the job:


SRE Career Track:

An SRE team member splits his time between development and operation-related tasks such as on-call duties, the job is exciting by nature and is very popular in the IT industry. Regardless of being a software engineer or system engineer, a person belonging to either domain who has an interest in the other can choose SRE as a courier.

Positives of the job:


Site Reliability Engineering vs DevOps: Salary

SRE DevOps
SRE Engineer Salary in India ₹12,00,000 /yr DevOps Engineer Salary in India ₹7,00,000 /yr.
SRE Engineer Salary in USA $1,20,000 /yr DevOps Engineer Salary in USA $1,07,000 /yr.


As the buzzwords of IT, SRE and DevOps bring automation to make the processes efficient and fast. Both methods share common practices, yet deliver a different product methodology. 

While a person working in a DevOps team has specific job responsibilities, a software engineer in the SRE team partly works as a system engineer. Both the job roles are popular and have huge demand in the IT industry. Either of the roles can provide you with excellent career growth and ample learning opportunities.
