DevOps is one of the hottest new trends and had the highest record number of attendees and speakers few months ago which coined as a term in 2009 by Patrick Debois.
DevOps is a software development approach which involves Continuous Development, Continuous Testing, Continuous Integration, Continuous Deployment and Continuous Monitoring of the software throughout its development life cycle.
DevOps is more than just a shift in how operations, development and business stockholders technically work together to develop new services.
These activities are possible only in DevOps, not Agile or Waterfall, and this is why Facebook and other top companies have chosen DevOps as the way forward for their business goals.
DevOps is the preferred approach to develop high-quality software in shorter development cycles which results in greater customer satisfaction.
There are many different types of benefits like technical, cultural and business benefits like below:
These terminologies may remove your concerns, questions, and confusion
Continuous Development (CTDD):
Continuous Development is a software development practice that extends test-driven development by means of automatic test execution in the background.
In CTDD the developer writes a test first but is not forced to execute the tests manually. The tests are run automatically by a continuous testing tool running in the background.
Continuous Testing (CT):
Continuous Testing is the process of executing automated tests as part of the software delivery pipeline to obtain immediate feedback on the business risks associated with a software release candidate.
For Continuous Testing, the scope of testing extends from validating bottom-up requirements or user stories to assessing the system requirements associated with overarching business goals.
Continuous Integration (CI):
Continuous Integration is a development practice that requires developers to integrate code into a shared repository several times a day.
Each check-in is then verified by an automated build, allowing teams to detect the problems early.
Continuous Delivery (CD):
Continuous Delivery is a software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. It incremental updates to applications in production.
Continuous Monitoring (CM):
Continuous Monitoring is the process and technology used to detect compliance and risk issues associated with an organization’s financial and operational environment. The financial and operational environment consists of people, processes, and systems working together to support and effective operations.
The demand of people with DevOps skills is growing rapidly because businesses get great results from DevOps.
A DevOps engineer must know how to manage the IT infrastructure that is needed to support software code in dedicated, multi-tenant or hybrid cloud environments.
He/she may be required to provide required resources, select an appropriate deployment model, direct the testing protocol to validate release and monitor performance after release.
Tasks may include preparing test data, analyzing results, troubleshooting problems and communicating issues back to development.
The DevOps approach to software development requires frequent, incremental changes to code versions, which means frequent deployment and testing regimens.
A DevOps engineer will work with development staff to tackle the coding and scripting needed to connect elements of code, such as libraries or software development kits (SDKs), and integrate other components such as SQL data management or messaging tools that are needed to run the software release on operating systems and production infrastructure. If DevOps is understood primarily as a mindset, it can get awfully fuzzy. But enough people are attempting definitions for us to offer the list of core DevOps attributes:
Now we are ready to take a look at the below DevOps diagram with various DevOps tools:
