In This article we have discusses what DevOps is and How does it work?
DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster rate than organizations that use traditional software development and infrastructure management processes is the goal.
Organizations can better service their consumers and compete more successfully in the market as a result of this increased speed.
If you want to learn DevOps, Linux Foundation is the best choice, they have courses like DevOps and SRE Fundamentals: Implementing Continuous Delivery.
With the help of the advanced cloud engineer BootCamp and a CKA discount, you may learn various cloud-native technologies while also achieving the Kubernetes CKA certification.
What DevOps Is and How It Works
DevOps eliminates the concept of “siloed” teams by bringing development and operations teams together. A single team with engineers working across the whole application lifecycle (from development and testing to deployment and operations) and developing a broad variety of abilities that are not confined to one specific role is often formed by combining these two teams.
It is possible that quality assurance and security teams will become more closely linked with development and operations teams as well as throughout the application lifecycle under various DevOps models.
When security is the primary concern of everyone in a DevOps team, the term “DevSecOps” is occasionally used to describe the situation.
These teams employ best practices to automate operations that have traditionally been labor-intensive and time-consuming.
They make use of a technology stack and tools that allow them to operate and grow apps in a timely and dependable manner.
These technologies also assist engineers in autonomously doing activities (for example, deploying code or supplying infrastructure) that would otherwise need the assistance of other teams, so increasing the velocity of a team even more than before.
Benefits of DevOps
Speed. DevOps practices let you operate at the pace you need to innovate quicker, adapt to changing markets better, and become more efficient at achieving business results.
Rapid delivery. When you accelerate the speed of releases, you may enhance your product faster and generate a competitive advantage.
Reliability. DevOps approaches like continuous integration and continuous delivery can assure the quality of application updates and infrastructure modifications so you can reliably deliver at a faster pace while keeping an ideal experience for end users.
Improved cooperation. Under a DevOps approach, developers and operations teams communicate closely, share responsibilities, and merge their processes. This lowers inefficiencies and saves time.
Security. You may implement a DevOps paradigm without losing security by leveraging automated, integrated security testing tools
Tools for DevOps
How does a team go about implementing DevOps practices?
Using the appropriate tools from the development environment to the production environment would result in a full DevOps toolchain that would allow applications to be delivered faster and better.
Tools are nothing more than DevOps facilitators. It is critical to recognize that automation is not synonymous with DevOps.
Jenkins is a good illustration of this. Jenkins allows you to get the most up-to-date code from version control systems such as Github and test it in a continuous fashion without the need for user intervention. This is referred to as the Continuous Integration procedure.
The next step is the deployment of the application. Configuration management tools such as Puppet, Chef, Ansible, and Saltstack can be utilized for this purpose.
With the help of these tools, you can write your infrastructure and describe how your infrastructure should look and function. This concept is referred to as “Infrastructure as code” in some circles.
The code is responsible for determining the current condition of your infrastructure. They assist teams in provisioning hundreds of thousands of servers, configuring themselves automatically, and deploying application code to those servers.
Containerization will be the next major change in the DevOps trend. Container technologies such as Docker assist the DevOps team in developing apps and deploying them to any infrastructure that supports Docker. The application would operate in the same manner as it did on the developer’s computer.
The adoption of DevOps will differ from organization to organization. Several corporations have changed the culture and processes of several teams in order to implement DevOps. Some firms will begin to develop different skill sets within the same team in order to implement DevOps. As a result, a collaborative approach is essential.
