Introduction
DevOps is the process of creating software through the collaboration and communication of software developers and IT professionals. DevOps stands for development and operation. Due to this, a single team would be able to do the development, testing, deployment, and operations of an application. DevOps has made the operations of software developers, quality assurance engineers, and system administrators simple and effective. Collaboration between the development and operation team is possible because of the DevOps. So while creating an application by the collaboration of the development sector, IT sector, and QC sector the quality of the end product would be really good.
Why DevOps is required in IT companies?
Before DevOps the operation process of an IT company was different all the departments were isolated. The testing and deployment process was isolated and because of this, the development of the application would require more time. The operating professionals in the testing, designing, and deploying section would spend a lot of time than the actual build cycles. The coding and operating team would also require additional time. We can use several DevOps tools to automate the software development phase.
- DevOps would allow the companies to collaborate the people, process, and tools to focus a lot on the customers.
- Shared responsibilities
- Fast feedback
- Repeatability
- Automation – Infrastructure as a code
- The quality and speed of the application delivery would improve a lot
- Product delivery can be done at the proper time
- The failure rate would be lowered
- Data can be protected through critical layers of data security
- Agility and stability of the critical business process can be increased
How DevOps toolchain can be utilized to build software?
- Develop
- Code review
- Unit testing
- Check-in
- Build
- Deployment
- Functional testing
- Security testing
- Performance testing
- Production setup and deployment
- Maintenance and upgrades
What are the major roles and responsibilities of a DevOps Engineer?
DevOps engineers must work with software developers, system operators, and other IT staff to manage the code releases. DevOps engineers should have basic knowledge of the software development languages. DevOps engineers should be able to do the coding and must be capable to work with the development staff to determine the coding and scripting requirements.
Major responsibilities
- Production and maintenance of software applications
- Should solve the problems regarding the application and must be able to troubleshoot the system
- Must be able to improve the quality and reduce the cost
- Should be capable to analyze the design and evaluate the automation scripts
What is the difference between DevOps and traditional IT?
| Traditional method | DevOps |
| The development team and the operating team would work separately to deploy the infrastructure properly | The development and the operation team would work together and this would give proper visibility to the infrastructure requirement |
| Information regarding the failover, data center, redundancy, and storage is not properly available from the developers. Developers would have a lot of knowledge about the application | All the details about the failover, redundancy, data center locations, and storage requirements are properly known because of the inputs from the developers |
| The operation team won’t have any idea regarding the progress of the development team. The operating team would do their work without any collaboration from other departments. | The operating team and the development team would work together and because of this, the operating team would be completely aware of the progress of the project. |
| After all the development process the application would be subjected to the load testing and this could crash the application and the release would be delayed | While doing the load testing the development team rectifies all the problems and the application would be released on time |
So there are a lot of advantages while using DevOps in the industry and without DevOps, there could loss of profit and time. Basically, we can describe DevOps as the collaboration of the development, testing, and operation team. So while creating any software the development team would interact with the operation and testing team and would create a proper plan to create the software with proper quality.
Who will benefit from DevOps certification?
- Operation manager
- System Administrator
- Project managers
- Business managers
- Software programmer/ Application developer
- Software tester
- Business analyst
- Network Administrator
How DevOps operation takes place?
Development
In this stage, the development of the software would take place, so in this section, the development process would be separated into small cycles.
Testing
In this stage, the testing process would take place and the bugs would be fixed.
Integration
In this stage certain functionalities would be added to the codes and testing would take place. The development would be carried out by frequent integration and testing.
Deployment
This is the deployment stage and in this stage, the code would be checked to determine that it won’t affect the website traffic.
Monitoring
In this stage, inappropriate system behavior would be checked.
DevOps workflow
In this stage there would be a visual overview of the sequence, it would also check the operation process.
What are the advantages of DevOps?
- The failure rate would be heavily reduced
- Reproducibility
- Maintenance can be easily done
- The proper delivery of the software on time
- The quality of the applications can be improved
- The risk would be reduced while creating the application
- Cost efficiency
- Working efficiency can be improved
How to start a career in DevOps?
DevOps are used not only in the IT sector it is also used in several other non-tech industries. Because of this, there are a lot of opportunities in this field. Starting a career in DevOps would require basic programming knowledge. Nowadays there are a lot of DevOps professionals and major companies would recruit professionals. If you are a certified professional then you would get a lot of opportunities. SMEClabs can help you with this, If you don’t have any basic software knowledge then we would train you for that. We would also provide placement assistance.
