Devops - What is Devops

Devops= Development + Operations
 DevOps is a combination of software development (Dev) and information-technology operations (Ops), It aims to reduce the systems development life cycle and provide continuous delivery with high efficiency and quality.
               It automate the process, developer to build a code , test a application and release the products much more faster.
               Compared to traditional method, Devops is used increase the speed of work and software release.       
               It aims to shorten the systems development life cycle and provide continuous delivery with high software quality

Waterfall model (or) Traditional method: 
1. Developer writing a code and pusing to the development environment.
2. Tester testing the code using automation and reporting the issues.
3. The developer fixing the bugs and again pushing to development environment.
4. Testing completed. now can see the changes in the development site
5. Same process will happens in the staging and production environment.

In this process time delay was more and code changes will happens on every environment depending upon their code.

In this Process developer have Pressure of work on old code and pending and new code was high because development and deployment time was high.

The time delay of developing the code for three environments as a result product will reach to the client or customers by late.

History of Devops:
                  Devops was invented in the year of 2009.
                  "Patrick Debois" from Belgium and "Andrew Clay Shafer" from the US both are met , discussed and invented the Devops concept.  

WHAT IS CICD:
                         
CICD: Continuous Integration and  Continuous Deployment:
              In the devops developers will work in the code and Continuously integrate,test and deploy the code.
              Using Devops no need to write a code for development, staging, production itself, just write a code once test it , deploy it thats it.   
           
Key features of DevOps:
  • Provides Collaboration
  • scalable
  • Automation
  • Has an holistic approach
  • Provides continuous build, test, integrate and deployment.
  • Reproducible
Devops is a concept.

For the Devops can use the several tools accordingly with their own requirements.

List of Tools used in the Devops:

  • Jenkins
  • Docker
  • GitHub
  • Docker
  • Ansible
  • Git
  • Bamboo
  • Kubernetes
  • Puppet
  • Nagios
