DevOps

DevOps is a set of practices that automates the process between software development and IT teams, in such a way that they can build, test and release software faster and reliably. The concept of DevOps is found in building the art of collaboration between teams that previously functioned in traditional ways.

DevOps is next to famous carry-on, bringing together the best of software development and IT operations.

It’s a firm contract between development and operations that accentuates a shift in mindset, better collaboration, and improved integration. It brings together agile, continuous delivery, automation, and much more, to help development and operations teams be more efficient, innovate faster, and deliver higher value to businesses and customers.

 

DevOps History

The DevOps movement started to unite some time between 2007 and 2008 when IT operations and software development communities raised feedback about what they felt was a catastrophic dysfunction in the industry.

They challenged the traditional software development model, who write the code to be organizationally and functionally apart from those who deploy and support that code.

Developers and IT ops professionals had separate goals, separate guidance, separate performance metrics by which they were judged. The result was unproductive teams concerned only with their own fiefdoms, long hours, botched releases, and unhappy customers.

If you’re using agile methodologies for planning and development, but still struggling to get that code deployed. You’ve heard a few things about DevOps and the seemingly magical effect it can have on teams and think “I want some of that magic.”

 

What’s in it for you?

Alliance and trust

Teams that work in siloes often don’t adhere to the ‘systems thinking’ of DevOps. ‘Systems thinking’ is being aware of how your actions not only affect your team but all the other teams involved in the release process. Lack of visibility and shared goals means a lack of dependency planning, misaligned priorities, finger-pointing, mentality, resulting in slower velocity and substandard quality. DevOps is that change in the mindset of looking at the development process holistically and breaking down the barrier between Dev and Ops.

 

Release faster and work smarter

Speed matters. Teams that adopt DevOps release more frequently, with higher efficiency and stability.

Lack of automated test and review slow down the release to production and poor response time kills velocity and team confidence. Different tools and processes increase operating costs, lead to context switching, and slow down momentum. Through automation and standard tools and process. teams can increase productivity and release more frequently with lesser discontinuity.

 

Accelerated resolution

Full transparency and seamless communication enable DevOps teams to minimize ETA and resolve issues faster than ever before.

If critical issues aren’t resolved quickly, customer satisfaction fails. Key issues slip through easily in the absence of open communication, resulting in increased tension and frustration among teams. Open communication helps Dev and Ops teams swarm on issues, fix incidents, and unblock the release pipeline faster.

 

Manage unplanned work

Unplanned work in reality impacts team productivity. With organized processes and clear prioritization, the Dev and Ops teams can better manage unplanned work while continuing to focus on planned work.

 

DevOps Lifecycle

1. Development

In this stage, the development of software takes place constantly. In this phase, the entire development process is separated into small development cycles. This benefits the DevOps team to speed up software development and delivery process.

2. Testing

QA team use tools like Selenium to identify and fix bugs in the new piece of code.

3. Integration

In this stage, new functionality is integrated with the prevailing code, and testing takes place. Continuous development is only possible due to continuous integration and testing.

4. Deployment

In this phase, the deployment process takes place continuously. It is performed in such a manner that any changes made any time in the code, should not affect the functioning of a high traffic website.

5. Monitoring

In this phase, the operation team will take care of the inappropriate system behavior or bugs that are found in production.
