About Application modernization
App modernization is the process of improving your current applications - or building entirely new ones - to take advantage of new, innovative tech. Having a plan for how you will modernize your application infrastructure is important. You can move the entirety of your application to a new environment. You can containerize different parts of your application and orchestrate the whole app with Kubernetes. Alternately, you can build cloud-native capabilities that connect to your existing apps, using APIs to deliver new functionality. From containers to microservices to DevOps and security, you need to understand all the different facets of app modernization when planning your move.
From monoliths to microservices – everything you need, right here:
-
Containers offer you a standardized way to run code independently of an environment, giving you freedom to develop from anywhere. Containers are small and meant to store code that is specifically related to the functionality you build, which is then loosely coupled to other containers inside the application. Docker is one of several popular open source tools for creating, running, deploying, and sharing containers.
-
As you're thinking about breaking down your monolithic application, you need to understand how your application's architecture will change. Refactoring it to a more microservices-based design will enable support for distributed functionality, scalability, independent code updates, rapid addition of new features, and deployment to different runtime environments.
-
Traditional security actions don’t scale with the deployment of containers, so you need to set up security to be a continuous effort across all your environments. Explore how to secure the integrity of your containers, applications, and your underlying infrastructure including new practices to isolate build from runtime.
-
Whether you simply modernize the runtime environment that your app uses or go all the way to strangle your monolith, some level of refactoring will improve the structure of your application. Make it easier to build, extend, test, and manage your app without impacting the overall capabilities delivered.
-
By using microservices, it's possible to build on top of your existing applications, whether on-prem or lifting-shifting to the cloud. By creating small amounts of code that exist for specific functionality, you can rapidly deliver value in a controlled manner.
