Advantages of containerization

Many enterprises nowadays opt for virtual machines to set up multiple operating system (OS) environments independently and simultaneously on the same machine. Virtual machines enable organizations to build and test software applications in multiple development environments without deploying and maintaining additional machine hardware. As an operating system (OS) level virtualization method, application containerization help businesses to deploy and run distributed services and applications seamlessly without launching an entire virtual machine for each application.

  1. Advantages of Containerization

  2.  Many enterprises nowadays opt for virtual machines to set up multiple operating system (OS) environments independently and simultaneously on the same machine.  Virtual machines enable organizations to build and test software applications in multiple development environments without deploying and maintaining additional machine hardware.  As an operating system (OS) level virtualization method, application containerization help businesses to deploy and run distributed services and applications seamlessly without launching an entire virtual machine for each application.

  3.  An enterprise can leverage containerization to run the same application or service on major operating systems like Windows, Linux and macOS with a single host and using the same OS kernel.  The container further includes the resources – files, libraries, and environment variables – required to run the application on each targeted platform.  Hence, application virtualization, unlike conventional hosting options and virtualization methods, helps businesses to run their distributed applications and micro-services optimally without investing in additional memory, storage space, and CPU. Many enterprises even opt for containerization to reap a number of additional benefits.

  4. Understanding Top 4 Advantages of Containerization 1) Optimize Application Virtualization  As an OS-level virtualization method, containerization extends and optimizes application virtualization. It does not require enterprises to run distributed applications and micro-services without launching multiple virtual machines. Hence, it becomes easier for them to reduce the additional overheads required to launch multiple virtual machines. At the same time, containers also help businesses to run additional applications with the same infrastructure by sharing storage, memory, and CPU.  They even facilitate OS kernel sharing to make it easier for users to run additional applications on a single virtual server. However, containers still reduce performance overheads by eliminating the need for replicating the OS frequently.

  5. 2) Simplify Deployment and Migration  In addition to facilitating overutilization of computing resources, containerization also helps businesses to keep their software applications portable.  The containers facilitate deployment and execution of a single app on multiple operating systems and multiple versions of each operating system.  Hence, it becomes easier for developers to port the application from platform to another without making any changes to its source code.  Also, the operation team can migrate the application to the cloud without managing library dependencies and OS environment variables.

  6. 3) Scale the Apps Smoothly  The speed and performance of a website or web application nowadays impact its user experience directly. Hence, enterprises need to scale their applications regularly to prevent user abandonment.  The conventional application deployment and hosting options often make it difficult for developers to scale an existing application. But the containers enable developers to scale the applications by adding new features or changing specific components without impacting the entire software.  For instance, the containers allow programmers to scale databases or functionality without scaling web server resources.

  7. 4) Manage Pipeline Efficiently  Each application passes through multiple environments during the software development lifecycle. The developers and testers have to set up multiple environments to build and evaluate the software according to exact business requirements.  They also need to set up multiple variants of these environments to manage the delivery pipeline efficiently. Containers make it easier for developers and testers to manage the pipeline covering development, testing, and deployment activities by providing a consistent test environment. After writing the code, the programmers can pack the app in a container.  The portable app can be tested and deployed in multiple environments simultaneously without extending delivery time.
