Exploring the Crucial Need for DevOps in Today’s Software Landscape

Let’s see the need for DevOps in today’s Software Development Lifecycle

Traditional: Development vs Operation

In the traditional way, there is no communication between the development team and the operation team and It leads to many problems while deploying in production

The development team will code and develop the application for a couple of months and test it after the development parts over they will hand it over to the Operation team for deployment

The Operations team should make sure of No downtime while deploying in millions of servers at the same time they have to handle huge traffic and it’s a really very tough

They are completely from different backgrounds

Development Team

• Programming languages
• Test frameworks
• Databases
• version control

Operations Team

• OS, mostly Linux
• Command line
• Scripting
• Monitoring

To deploy it in production there should be communication between Development and Operations

• Many things to consider during the deployment
• The environment needs to be prepared

But the development team will document everything and handle over it to the Operations team. The operations team try to understand the document but still there will be some missing parts and not clear enough

So there will be the late release of software and cannot complete within expected time

How to solve it?

There were DevOps came into the picture. DevOps was just a way of working between DEV’s and OP’s. That become its own role and job, Many concepts and tools came there after.

The DevOps engineer should know about the Development and as well as Operations to solve all those kind of problems

Other than that DevOps engineers should know their specific kind of things like Docker, Kubernetes and Cloud etc..\

DevOps Tasks and Responsibilities

• Test
• Build
• Push
• Deploy

Test:

DevOps teams are responsible for implementing robust testing processes throughout the software development lifecycle. This involves creating and executing test cases to ensure the quality and reliability of the code. Automated testing is often emphasized to catch bugs early and facilitate continuous integration.

Build:

The build process involves compiling the source code, integrating various components, and creating executable binaries or artifacts. DevOps professionals use build automation tools to streamline this process, ensuring consistency and efficiency. This step is critical for producing reliable and reproducible builds.

Push:

After successful testing and building, the code is pushed to a version control system, such as Git. This step ensures that the latest code changes are accessible to the entire development team. It also facilitates collaboration and enables version tracking, allowing developers to work on the same codebase seamlessly.

Deploy:

Deployment involves releasing the application or system into a production environment. DevOps practitioners focus on creating automated deployment pipelines to reduce manual intervention and decrease the chances of errors. Continuous Deployment (CD) practices aim to deliver new features or updates swiftly and reliably to end-users.

Agile and DevOps

DevOps and Agile share values of collaboration and customer focus. They both advocate for cross-functional teams and iterative development. Continuous Integration and Delivery (CI/CD) practices in DevOps align with Agile’s emphasis on frequent releases. Both methodologies prioritize feedback loops for continuous improvement. The combination of DevOps and Agile creates a cohesive approach that accelerates development, fosters adaptability, and enhances overall software delivery efficiency.
