What is DevOps?
The term DevOps combines two words: Software Development and Operation. It is a set of practices that brings software development and operation teams together to develop software.
The goal of DevOps is to combine the day-to-day tasks of integrating development, quality control, deployment, and software development into one continuous series of processes.
It allows enterprises to create and improve their products faster than traditional software development approaches. And it is rapidly gaining popularity.
Responsibilities of a DevOps Engineer
- Developing and organizing new development tools and infrastructure.
- Understand stakeholder needs and communicate to developers.
- Work on ways to automate and improve the development and approval process
- Test and examine code written by others and analyze the results
- Ensuring system security and protection from cybersecurity threats.
- Identifying technical issues and developing software updates and “fixes.”
- Work with software developers and software engineers to ensure that development follows an established process and works as intended.
- Participation in project planning and project management decisions.
SRE Vs. DevOps
SRE and DevOps both approaches have found a balance between two poles and complement each other well. However, SRE culture prioritizes reliability over the speed of change, while DevOps emphasizes agility at all stages of the product development cycle.
DevOps aims to accelerate the delivery of high-quality software by shortening the software development life cycle, eliminating silos, and combining and automating the work of software development and IT operations teams.
Site Reliability Engineering (SRE) uses software engineering to automate IT operational tasks that would typically be performed by system administrators. These tasks include production system management, change management, and incident response.
Both the practices reduce the gap between Development and Operations teams. But we can sum up the key difference like this:
The DevOps team is focused on core development, while the SRE team is all about core implementation.
DevOps engineers are working on a product or application. They take an agile approach to software development and help build, test, deploy, and monitor applications with speed, quality, and control.
SRE engineers are constantly giving feedback to this core development team. SRE leverages operational data and automates IT operational tasks, and accelerates software delivery while minimizing IT risk.
DevOps and SRE engineers possess different skill sets. DevOps engineers are ones who love to code software. They write code, test it, and put it in production to get a line of applications to solve the problem.
SRE engineers are more exploratory. They analyze the software thoroughly to find out why the problem occurred. Also, they try to eliminate repetitive problems. They are responsible for automating repetitive tasks.
Automation is the key used to reducing the workload. Therefore, automating a few software practices is essential. In this way, you can utilize your energy and time to focus on innovations.
You don’t have to automate everything. But if you’re doing the same task over and over, why not use automation to reduce your workload?
DevOps automates deployment as well as tasks and functions. SRE automates redundancy and manual tasks. Later, it turns them into programmatic tasks to keep running the software.
In a nutshell, DevOps focus is shifted more on a cultural and philosophical side, while SRE is more pragmatic and practical. However, they can still be referred to as two sides of the same coin as they complement each other well, just like how SRE tools and techniques complement DevOps philosophies and practices.
