Introduction To DevOps

 

Introduction to DevOps

DevOps is more than just a set of tools or practices. It’s an organizational change that focuses on collaboration, automation, and continuous delivery. It breaks down the divisions that generally separate development and operations teams, encouraging shared responsibility for the entire software lifecycle.

Now, how exactly is this achieved? We will discuss this as we move further.

Need of DevOps

Imagine a scenario where the software development team puts in a lot of effort to make cool apps. But when it’s time to launch, the operations team faces problems. This causes delays, and errors, and messes up the smooth flow from making the app to launching. This division may restrict progress and hinder a company’s ability to stay competitive in the market.

Why DevOps? Why not other methods?

DevOps addresses these challenges by encouraging collaboration, communication, and integration between development and operations teams. It aims to break down the barriers that traditionally exist between these two separate entities. By promoting a cultural shift and utilizing cutting-edge tools and practices, DevOps works to achieve critical objectives, such as speed up delivery, enhancing reliability, and encouraging innovation.

Differences Between Agile and DevOps

Agile	DevOps
Agile majorly focuses on collaboration, customer feedback, and small rapid changes	DevOps brings development and operations teams together
It does not focus on automation	It focuses majorly on automation to increase efficiency while deployment
The development process is inherent for Agile, making it less focused on testing and implementation processes	DevOps focuses on all development, testing, and implementation phases with equal importance
It overcomes the gap between customers and developers	It overcomes the gap between the development and operations folks

DevOps LifeCycle

DevOps focuses on bringing all the development, operations, and IT infrastructure guys, including developers, testers, system admins, and QAs, under one roof. Hence, all these people together are called DevOps engineers.

DevOps engineers share the end-to-end responsibility of gathering information, setting up the infrastructure, developing, testing, deploying, continuously monitoring, and fetching feedback from end-users.
