DEVELOPMENT OPERATIONS (DEVOPS)

What is DevOps ?

DevOps is the practice of operations and development engineers participating together in the entire software development life cycle.
The DevOps is a combination of two words, one is software Development, and second is Operations. This allows a single team to handle the entire application life-cycle, from development to testing, deployment, and operations.
DevOps helps you to reduce the disconnection between software developers, quality assurance (QA) engineers, and system administrators.
DevOps promotes collaboration between Development and Operations team to deploy code to production faster in an automated & repeatable way.
DevOps automates a huge part of the software development life cycle which leads to:
1. less human errors.
2. quick feedback, which leads to quick bug fixing.
3. building and testing of each phase in parallel to the development. _____________________________________________________________________________________________________________________

After the design-build, the testing and deployment are performed respectively. That’s why they consumed more time than actual build cycles.
The team members are spending a large amount of time on designing, testing, and deploying instead of building the project.
Manual code deployment leads to human errors in production.
Development and operation teams have their separate time-lines and are not in sync, causing further delays.

So that why we need DevOps, to solve these problems and stop making delivery delays because of simple problems.

key features of DevOps architecture

Automation can reduce time consumption, especially during the testing and deployment phase.
Automation will lead in catching bugs quickly so that it can be fixed easily.
For continuous delivery, each code is defined through automated tests, cloud-based services, and builds.

The Development and Operations team collaborates as a DevOps team.
The teams share their responsibilities and work closely in sync, which in turn makes the deployment to production faster.

The integration phase is merging the existing code is combined with new functionality and then tested.
Continuous integration and testing enable continuous development.
continuous integration and delivery are implemented to deliver in a quicker, safer, and reliable manner.

It ensures the application to interact with only those resources that are concerned with the environment in which it runs.
The configuration file can be written during deployment, or they can be loaded at the run time, depending on the environment in which it is running.
