So first of all, we'll understand what it's?
The term DevOps is a combination of two words Dev + Op
Dev - Development - developing a product.
Op - Operations - releasing the product.
Traditionally, in the Software Industry, these two areas were kept separate. The developers wrote code and the operations team dealt with production and maintenance.
Before Devops came into picture, the model that is used to build the software is Waterfall Model.
Waterfall Lifecycle Mode
We'll understand what Waterfall Model is:- In the waterfall model, the project is done step by step as we can see in the above diagram, but the problem with it is that when one of the changes we want to do in the project then we have the start the whole process. So that's the major disadvantage of this model by this, we waste too much time here, in order to deal with the new change demand. But, nowadays the application changes more frequently, and the customer wants the demand changes faster. But, we can't afford to waste precious time, and we don't want any downtime for the applications.
Nowadays Agile model is used It allows programmers to make a prototype and get the prototypes to the client, with the requirements faster, and the client sends his requirement back to the programmer with feedback.
Agile methodology cycle
In this, the engagement cycle is about two weeks, which is much faster than the traditional waterfall model.
Advantage of the Agile Model
Client requirements are better understood because of the constant feedback.
The product is delivered much faster as compared to the waterfall model.
Disadvantage of the Agile model
The product gets tested only on the developer's local computers and on test environments but, not on production systems.
Developers and the operations team are working on the same objective but don't communicate enough.
The advantage of the agile model is good, but its disadvantages are worse.
So here DevOps comes into the picture, which is the evolution of the Agile Method.
In the case of DevOps CI/CD, if any new change we want to add then at that time we can add the change in the product. And we can check (operations ) that the change has no error, and we can deploy it, and by doing this we will have zero downtime. And the company's wealth and time both will be saved.
- DevOps addressed the gap between Developers and Operations
- Development team will submit the application to the operations team for implementation
To shorten the systems development life cycle while delivering features, fixes, and updates frequently in close alignment with business objectives.
The main reasons for implementing a DevOps culture within an organization are:
Faster time to market: DevOps culture promotes an agile and iterative approach to software development which can reduce overall project lead times and allow for faster releases to market.
Higher quality code: With continuous integration and testing practices, DevOps teams can identify and address issues earlier in the software development lifecycle, resulting in higher quality code.
Improved collaboration among teams: DevOps culture facilitates collaboration between development and operations teams, which helps to break down silos and promote a culture of shared responsibility.
More efficient use of resources: DevOps practices can help to optimize resource allocation, leading to more efficient use of time, talent, and infrastructure.
In summary, DevOps can improve the overall capability and agility of an organization to deliver high-quality software products to market faster while improving collaboration, communication, and trust among all relevant stakeholders.
