Containerization as a Method of App Modernization

  • March 16, 2018

    Many businesses, especially large venerable businesses, rely heavily on legacy applications. This presents challenges in the age of accelerations where innovation and speed to market are moving faster than ever.

    App modernization remains a top priority for businesses in their digital transformations. Moving applications to the cloud can bring tremendous benefits such as low cost maintenance, innovative agility and increased ability to outsource. However, this isn’t always the best solution for businesses depending on what their priorities are. There are a multitude of ways to modernize applications versus scrapping legacy systems and starting from scratch. This largely depends on the scale of the modernization project and the budget. A recent TechTarget article outlines the options of using containerization and microservices as an approach for app modernization.

     

    What is Containerization?

    Technological obsolescence is commonplace in today’s enterprise world. App modernization is more of a state of continuous improvement over a one-off project. One of the most economical ways of modernizing apps is through containerization. RisingStack defines application containers as operating system virtualization. The container makes a group that holds the memory, central processing unit and process resources. It creates a barrier that keeps the processes inside the container from seeing or interacting with processes outside of it. All the container share the same host. Containers are typically used as an operating system or for application packaging. Each application package is designed for a specific function and service making it easier to modernize on an individual level.

     

    Portability for Modernization

    It can be difficult to modernize legacy applications as a whole designed for a specific purpose or function. Making tweaks to a legacy application may cause unintended disruption and ripple effects across the entire system. However, applications in containers contain all the variables that can impact its functionality taking a lot of the guesswork and contingencies out of the modernization process.
