As per application economy today, businesses have become software businesses, and DevOps has become one of the most valuable business disciplines for the enterprises. With the help of DevOps, quality, and speed of application delivery have improved to a great extent.
DevOps represents a change in the IT culture with a complete focus on rapid IT service delivery through the adoption of agile practices in the context of a system-oriented approach.
DevOps is all about the integration of operations and development process. Organizations that have adopted DevOps noticed 22% improvement in software quality and 17 percent improvement in application deployment frequency that results in 22 percent hike in customer satisfaction and 19 percent revenue hikes as a result of the successful DevOps implementation.
DevOps word in itself is a combination of two words one is Development and other is Operations. It is neither an application nor a tool; instead, it is just a culture to promote development and Operation process collaboratively. As a result of DevOps implementation, the speed to deliver applications and services is increased.
DevOps enables organizations to serve their customers strongly and better in the market. In other words, we can say that DevOps is the process of alignment of IT and development operations with better and improved communication.
There are tons of stories about the DevOps origins, but it is not created out of the whole cloth. Its seeds were planted many years ago and recently nurtured by expert IT professionals in several disciplines. Two primary ancestors of DevOps are given below:
“When you are going agile without DevOps, it is like racing with a tractor instead of a car. You can do laps, but it will not move faster, and ultimately you are going to waste a lot of fuel without having any fun.”
DevOps implementation has increased the rate of software delivery and the revenue for business stakeholders. Following listed reasons are the most considerable ones that led to the creation of DevOps.
To avoid the hassles mentioned above and non-collaborative performance measures, there was an urgent need for robust IT technology like DevOps to satisfy business owners and stakeholders.
Let us compare the waterfall model with DevOps to see what changes DevOps brings to the IT. Take a few assumptions for this comparison like the application has to make live in the next two weeks, and more than 80 percent coding is complete. We assume that application has been launched recently and the process of buying servers to ship the code has just begun.
|Once the order for new servers is placed, the development team starts working on testing. The development team has to continue with heavy paperwork as required by enterprises to deploy the infrastructure.||Once the order for new servers is placed, the development team and operations team start the paperwork to set up new servers that result in better visibility of infrastructure equipment.|
|Projections about failover, data center locations, redundancy, and storage requirements are not clear as no inputs are available from the development team even if they have the depth knowledge of the application.||Projections about failover, data center locations, redundancy, and storage requirements are 100 percent clear because of accurate inputs given from the development team.|
|In old software development processes, the operations team has no idea of the progress of the development team. Operation team has to prepare a monitoring plan as per their own understanding.||In DevOps, the operations team have a complete idea of the progress of development. Operations team and development team work together to develop a monitoring plan that caters to the current business, and IT needs.|
|Before go-live, the load testing may crash the application, and the release may get delayed. It affects the overall cost of the project and project delivery deadline.||Before go-live, the load testing makes the application a little slow. The development team quickly fixes bottlenecks, and the application is released on time.|
Developers and Operations engineers are two different organizational teams, and if these teams are found to be on the wrong track that it signifies that you need DevOps. We have consolidated here seven signs that can help you in getting the answer whether you need DevOps or not:
“DevOps is not a goal but a never-ending process of continual improvement.”
The DevOps offer continuous integration and continuous delivery. It makes the product delivery cycle quicker, and enterprises become able to launch the software timely without compromising its quality.
Following are the factors that will improve as a result of DevOps implementation:
“DevOps is truly not just the unicorns of big IT hubs like Amazon, Google, Facebook, etc. but it can be adopted by almost any organization today instead of their sizes.”
DevOps is basically an integration of development and operation process. One cannot implement DevOps without understanding its lifecycle. Following steps are included in the DevOps lifecycle:
This is the first stage of DevOps lifecycle in which development of application takes place constantly. The entire development process is broken down into small steps or development cycles. As a result of this, the speed of software development and delivery is increased.
Selenium like testing tools is used to speed up the overall testing process by quick identification of errors and fixing the bugs.
New functionalities are integrated with the prevailing code, and testing of new code takes place. Continuous integration and testing help in the continuous development process.
Continuous deployment is the part of DevOps lifecycle. When it is performed in the right way, then it can affect the overall functioning of a high traffic website.
Inappropriate system behavior is managed by monitoring. Through proper monitoring, the bugs are found and fixed in a hassle-free way.
These are the building blocks for any DevOps application. As per DevOps culture, a group of Engineers is responsible for each stage of DevOps application development, including developer, system admin, testing, and others.
Workflows show a visual overview of sequences in which inputs are provided. It tells you about actions and outputs are generated based on operational processes. It has the ability to arrange and search for jobs that are frequently requested by users. It gives you the ability to mirror the ideal processes in configuration jobs.
DevOps solves development challenges in the following ways:
As far as operation process execution is concerned, then implementation of DevOps improves the operational processes in the following ways:
