Your App Modernization and Cloud Migration To-Do List
Accelerate innovation. Optimize performance. Reduce infrastructure costs. Leverage scalability. Improve customer experiences. They’re among the benefits that can be realized with a cloud migration. Unfortunately, many companies don’t realize that getting the cloud’s full value requires more than just moving their apps there.
Not all apps were developed to run in the cloud, particularly legacy apps built using monolithic architecture. Developing new cloud-native apps would solve the problem, but that’s expensive and can take considerable time. Plus, many legacy apps simply aren’t replaceable for a variety of reasons.
The better option is to modernize them as part of a cloud migration project. App modernization takes legacy apps and modernizes its platform infrastructure, internal architecture, and/or features. This enables them to continue performing their intended function and leverage the benefits of the cloud.
Industry analysts and enterprises alike consider Amazon Web Services (AWS) to be among the best platforms for app modernization projects. But even with the abundance of resources, AWS offers to facilitate app modernization, there are still a number of things that have to happen as part of the overall cloud migration process.
The following are some of the steps that can help ensure success:
To determine which apps can and should move to the cloud, you have to know what you have. Compile a list of all your apps. Reach out to all departments to account for those you may not be aware of due to shadow IT. Map their interdependencies with your business services and other apps.
Next, list out the characteristics and requirements of your apps. For example, note for each app:
Some of your apps may be better suited to the cloud than others and require little or no modification to move there. Compile a list of them. They may include:
Determine where your apps fit within a cloud migration strategy framework. While the various cloud services providers, industry analysts, and consultants have their own frameworks, most focus on what are referred to as “R” strategies. They include:
If there isn’t a SaaS option that can do what you need to be done, the app can be rewritten from scratch using cloud-native app development. There are time and money involved, but it ensures you of an app that does what you need it to do. It’s also the best way to make sure it’s optimized to fully leverage the benefits of the cloud.
Once you know which apps you want to move to the cloud and what strategy needs to be used to prepare them for the migration, you can determine the budget, staffing, and tool needed to make it all happen. Depending on the resources and expertise you have in-house, you may wish to enlist a third-party company that specializes in app modernization and cloud migration.
Keep in mind that even the best-formulated app modernization and migration project can encounter challenges. For example, some legacy apps still depend on flat files and hierarchical databases. As such, they can’t meet the demands of big data, mobility, social media, and artificial intelligence. That can make data store modernization as important as app modernization. Moving data to modern data stores requires specialized knowledge.
There’s also the reality that apps don’t always run reliably when moved to a new environment. Containers resolve that issue by wrapping a piece of software in a package with code, runtime, and everything it needs to run. This ensures the app runs the same, regardless of the environment. Like data store modernization, using containers and container orchestration platforms requires expertise that many internal IT teams may not have.
