Why is docker so popular now?

 Developers and system administrators can take equal benefits from the Docker tool. Docker remains a very integral and useful part of DevOps. Anyone can learn Docker by docker and Kubernetes online training. Docker has made it easier to write codes by changing priorities. Developers now can focus on making the program instead of system configurations. Any developer can start Docker development by using ready to use docker programs. Docker minimizes the scope of systems that are needed and increases flexibility in application development for said systems. It is a very small tool so it has low system requirements and leaves a small footprint. So anyone can learn a DevOps course in Hyderabad. 

Reasons why Docker is so popular

1. Low system requirements: virtual machines can be popular but they are also huge. They are comprised of complex and huge hardware. On the other hand, containers use shared operating systems so they are much more efficient than virtual machines. The operating system is not fully used by any container as they rest on an instance of the OS. If you have a perfectly tuned container, you can easily run more server instances on the same machine rather than running on a virtual machine. 

2. Continuous integration and deployment: developers maintain good care of their Docker apps. They can continually deploy and integrate codes with much ease using docker. DevOps Methodology and DevOps Lifecycle enables shared repository code integration and makes deployment efficient and quick. 

3. Code isolation: DevOps Engineer and developers can isolate their codes to just a single container if they feel the need to. Program management, modification, and updates become easier with this process. Enterprises can easily break large applications into smaller counterparts, and then deploy it using Dockers. Docker’s containers are also very easy to be deployed on the cloud so that it can be combined into DevOps application. 

4. Local development environment: A developer can set up a local development environment for CI/CD processes. Multiple development environments can be set up from the same host with unique software, configuration, and even operating systems. An application can be easily tested for diverse servers and anyone can work on the same project with variable settings irrespective of the local host environment. 

5. Increased efficiency: a development team with strong DevOps knowledge deploys software 200 times faster than any low performing IT department and can recuperate 24 times faster as well with very low failure possibilities. Businesses also use DevOps for testing applications in a secure and safe environment. Docker is one excellent tool to deliver some applications.

6. Quick application portability: containers need to be packed, shipped, and run in a self-sufficient container. This helps applications get instant application portability. Applications can be run virtually from anywhere and their deployment is more efficient.  

Conclusion

DevOps Docker can help developers take control of their software development. Applications can be deployed and installed without much hassle with Docker. Developers who use dockers are way faster than any other developer as all systems are equal in size. The program is small itself and enables a plethora of features such as code isolation. It is a very efficient way of pushing codes and has a very small fingerprint. The system requirements for running dockers are usually very low so it can be learned and used in any IT organization with much ease. 

The aspirants who want to learn using Docker can do so by any docker and Kubernetes online training, which can help them secure a well-paying job. Jobs that require Docker are well paying because this is a new age technology that came out in 2014.
