Nowadays a new buzzword “DevOps” has emerged in the market. Technologies are changing rapidly and hence companies are moving towards agility. This need of agility in Industry gave rise to “DevOps“.
In traditional SDLC approaches, companies may face difficulties to match the gap between Developers, Operations team and production. Such challenges have the most impact on the cost, schedule and reputation of an organization. Therefore automation throughout the Life cycle, continuous feedback and process improvement are the main reason for adopting DevOps.
What is DevOps?
DevOps basically deals with three components i.e. development, operations and quality assurance. “Development team” is especially relevant to give business value to the end-users while “Operation team” mostly concerns with the stability of the production environment. QA ties together development and operations which help them to collaborate with the software and applications up and running. Although individually they deliver different values and together their target is to increase an efficiency of the organization.
Elements of DevOps
Where did it come from?
An increasing demand for innovation on the technology front has given rise to DevOps. The DevOps movement comes from the Agile System Administration movement and the Enterprise Systems Management (ESM) movement.
For better understanding let us consider two scenarios and understand what role DevOps plays in an organization:-
|1) In this approach, most development uses waterfall method which was time-consuming because the size of the batch was big.||1) In this approach, small batch size was taken for easy understanding, continuously test and less risk.|
|2) Codes were large and bundled into the release which results in jammed production and lowers the productivity, hence more risk.||2) Code sizes are small which results in continuous production and increase the productivity, therefore, reduce risk.|
|3) Here everyone works in skill centric environment where certain departments or sectors do not wish to share information with each other in the same company which probably leads to the inefficiency in an organization.||3) Here the team is divided into small cells that consist of developers, testers, business analysts and operators. Hence an idea can move from one stage to another without any obstacle.|
|4) More money is invested in schedule planning systems which are quite sensitive and inaccurate. As a result, this consumes more time to manage with systems.||4) Smaller batch sizes, dedicated teams and automated processes make scheduling simpler to operate. No waiting for infrastructure since it has already been defined and automatically provisioned.|
|5) Since the batch is huge, reports created by specialist are also huge which goes mostly unread.||5) Batch size is divided into small cells, each cell gathers their own data. Therefore reports are small in size and taken into consideration.|
|6) Here cost cutting is done but they keep capacity constant which makes difficult to achieve target or outcome.||6) DevOps make flows for work which calculates productive area as well as the waste area in the process. As a result, an organization can focus on their goal.|
Building blocks of release pipeline:
- Continuous Integration(CI):
- It is a development process in which developer requires to update their code in order to share repositories every day. That is furthermore verified by teams to identify problems. CI helps you to deliver software rapidly.
- CI helps you to deliver software rapidly.
- In addition to this, It takes less time to identify the problem and helps in adding new features to it.
- Continuous Delivery:
- Continuous delivery aims to do releases in many easy ways so that any change in software can be updated on a push of a button.
- Consequently, helps to take user feedback simultaneously in according to which software makes the update.
- Furthermore, this also helps the team to build a right product.
- Continuous Deployment(CD):
- Continuous Deployment is a strategy for software releases wherein any commit that passes the automated testing phase automatically release in the production deployment.
- This provides a single view throughout all applications and environments.
- In addition to this CD improves the overall productivity of the organization
- It automates the repetitive tasks and hence focuses on actual testing.
2016 vs 2015 DevOps Adoption from RightScale Dev
- DevOps adoption increased from 66 percent in 2015 to 74 percent in 2016.
- Adoption in Enterprise is 81% while adoption in small companies is 70%
• Enterprises are adopting DevOps for various purposes such as for projects, to widen company or for business units.
Benefits of moving to DevOps:-
1) Ultimately, the primary goal of DevOps is to deliver higher quality software to end users which result in chances of increasing revenue of the organization.
2) DevOps provides the ability for teams to deliver innovation rapidly.
3) DevOps leads to empowerment of every individual, ultimately resulting in more motivated employees producing better, timely output.
4) Excessive, costly rework is avoided while creating the user experience. Since adopting DevOps saves money.
5) Agility framework had helped to achieve business outcomes and competitiveness for the companies.
6) DevOps principles maintain the stability of the product which ensures to monitor everything, to know every change and to make everyone understand how each release impacts quality.
7) DevOps promotes a culture of continuous learning and improvement which furthermore keeps an organization agile.
And much more……..
There are many purposes to adopt DevOps, it depends on the need of organization.
