There are a number of cloud storage providers that offer apps to help you move your apps to the cloud. However, before you can move your apps to the cloud, you'll need to set up an account with a provider and choose a plan that meets your needs. Once you've done that, you can use the app to upload your apps to the cloud.
Before you begin, it's important to note that not all apps can be moved to the cloud. In particular, apps that rely on hardware or other devices may not be able to run in the cloud. Additionally, some app developers may not allow their apps to be moved to the cloud. As such, it's important to check with both your app developer and potential cloud storage providers before moving forward.
Assuming everything checks out, moving your apps to the cloud is relatively simple: just download the app from your chosen provider and follow instructions for uploading your app data. Depending on the size and complexity of your app, this process may take some time; but once it's done, all of your app data will be stored securely in the cloud.
