An Extensive Guide To Containerization And Some Of The Best Practices
With the expansion and explosion of cloud computing arena, the need for containers is just getting a rise. If you are a tech-savvy programmer, you would have heard of “containers” and how they are changing the game of complex programming. • The usage of the same is gaining all the attention from the industry. And it’s not a surprise that with so much of ease and flexibility, big Giants like Microsoft, Google and Amazon are adopting this approach. • Few quality highlights are Adaptability, Efficiency, and High speed. Container approach simplifies dozens of task and also manages many applications. Erstwhile, managing hardware dedicatedly was a costly affair and more like a Tetris game. But container satisfied it all. • A Container is a small file that combines the application code along with the libraries and other dependencies which are needed to run.
Regardless of the environment in which the application has to be run, a container packages the application libraries, environmental variables, software binaries configuration and more. It is a small file but with maximum flexibility and runs at a super speed owing to the usage of some underlying host operating system’s resources. This also means various applications will have one underlying operating system and treats each application on its own. • rogrammers yet may not have hands-on experience of working with containers and IT environment management tools. But containers definitely has made life easy for hundreds of thousands of developers and have increased the application performance with minimal effort. • Here is the guide that sheds some light on the best benefits of working with containers and have an efficient IT environment management. Administrators can create containers and run many of them at a time, which consequently reduces the computing time and storage load.
They are cloud-friendly in nature, which allows the automatic deployment of the same. Few other benefits are: Lightweight: It is not required to have a full OS installed per application. It shares the machine OS Kernel which makes them small and compact in size and easy on resources.
Efficient and Scalability: Since the size of the container is considerably small, they can easily be spin up and deleted whenever required. It makes the IT environment agile, which further helps in growing business leaps and bounds. It shouldn’t come as a surprise to have thousands of containers in a single computing environment.
Portable: As described above, a container has all the dependencies, libraries covered with it. This means it can run on a variety of computing environments without consuming much time and making the complicated process much easier. Also, it extends support to automation replacing the manual scripting. This way, it creates a more guaranteed and maximised portability.
Supports Agile Development: Containers are created, keeping in mind the cloud-first development. Being agile, containers support continuous integration for a DevOps environment.
It offers enhanced computing capabilities: An application can be divided into many domains all within one single container. Owing to the highly portable nature, the execution of containers on different cloud platforms becomes easy and efficient. The developers have the freedom to choose the platform on which they want their application to run depending on the cost and performance efficiency requirement.
Leverages policy-based Optimization: The automation facility provides an extra layer which will help in locating the best platform to execute the application. Also, the containers deal automatically with the configuration and meet the requirement.
The next part focuses on practices that can be implemented for scaling containers: • Invest sufficient time for designing a proper architecture of container-based applications. Insufficient and poor designs often lead to scaling issues with containers; • It is advisable to have a proof of concept in order to find out the real scaling capabilities. It is allowed to take the help of automated testing tools for stimulating the workloads and a considerable amount of data for Test environment management tool. • Do not follow the approach followed by others. The company’s requirement may differ from the one you are taking inspiration from. What works for them may not work for your company. • Do not compromise or overlook the security and governance of the application. Along with the scaling of containers, even these properties have to be scaled.
The scaling factor may confuse and look a bit tricky, but with sufficient understanding and knowledge of the containers and the technology, you can bloom out the right scalable strategy. Containerization thus gives wings to the administrators for running more applications than ever before. It helps the team build robust and agile applications in less time and involving fewer efforts. So let’s get Containerizing and cope up the business with the changing business scenario.
