Brief Introduction About DevOps
Software Development = Dev
Operations = Ops
“DevOps” as a term was first authored in 2009 by Patrick Dubois, who became one among its main advocates. Simply put, DevOps may be a combination of software development and operations and as its name suggests, it is a melding of those two disciplines so as to stress communication, cooperation, and attachment between the generally independent designer and IT activities groups.
DevOps isn’t employment title, nor a strategy, but are often thought of more as a culture of labor.
The key idea is that instead of separating the responsibilities of a software development team into the people that write the code and the people that run the systems that run the code (servers, databases, build tools etc.), a team is formed from a various set of individuals , each capable of brooding about the way that these two topics intertwine. A DevOps culture guarantees that designers think about how the application is run on the equipment however much the Operations public see how the product is made (which language, system, and so on)
Maybe than seeing these as two unmistakable gatherings who are at risk for their particular undertakings yet don’t actually cooperate, the DevOps procedure perceives the relationship of the 2 gatherings. By incorporating these capacities together group or office, DevOps assists a partnership with sending programming all the more habitually, while keeping up with administration security and acquiring the speed important for more advancement.
And, within the end, most are ready to deliver the simplest results and overall experience possible to the customer.
DevOps might be a joint effort among improvement and activity groups, which empowers ceaseless conveyance of uses and administrations to our end clients.
Benefits of DevOps
- Continuous delivery of software
- Better collaboration between teams
- Easy deployment
- Better efficiency and scalability
- Errors are fixed at the underlying stage
- More security
- Less manual intercession (which implies less odds of blunder)
Which certification is best for DevOps?
- Docker Certified Associate.
- Certified Kubernetes Administrator.
- Microsoft Certified Azure DevOps Engineer Expert.
- AWS Certified DevOps Engineer.
- Google’s Professional Cloud DevOps Engineer.
- Hashicorp certified Terraform Associate DevOps.
Now let’s understand How DevOps works?:
DevOps primarily works one might say via computerizing a great deal of the assignments.
On the off chance that we can consider the Software Life Cycle isolated into these five cycles:
- Continuous Development
- Continuous Testing
- Continuous Deployment
- Continuous Monitoring
- Continuous Integration
Every one of the cycles are essential for the production of a productive DevOps Life-cycle.
Continuous Development :In this process the code is first developed then pushed to a version system . Every-time a replacement code is pushed, a special version is made on the version system , it keeps track of all the various versions that are pushed thus far .
eg: Version 1 : print “hello”
Version 2: print “hello world”
Tool Used in this stage – GIT
Continuous Integration :This process deals with integrating the various stages of DevOps Lifecycle & therefore is that the key in automating the entire process.
Tool Used in this stage – JENKINS
Continuous Testing : In this stage the code is pulled from a version system then built and run on a testing server. Pre-characterized tests are naturally executed on the code.
If the piece of code passes all the test cases, then it’s pushed to the assembly Server
Tool used in this stage – SELENIUM
Continuous Deployment : Here the code is automatically deployed on the proper server with the proper configurations and within the right environment.
Tools utilized in this stage – DOCKER, PUPPET, ANSIBLE
Continuous Monitoring :The piece of code conveyed is persistently observed for bugs or crashes and for inputs from the client base. These sources of info are then used to work on the application in the following Lifecycle advancement stage.
Tool used in this stage – NAGIOS
Using the tools in each of those stages helps in propagating a DevOps culture and also helps in creating an efficient and top quality code pipeline.
