Move to Platform-as-a-Service (PaaS). For commoditized services such as databases, web servers, file servers, container orchestration, moving to a PaaS allows for a serverless architecture. A serverless architecture negates the need to manage and patch operating systems, middleware and manage server instances. This also reduces an organization's IT LifeCycle Management burden. Users sometimes worry that using PaaS will cause vendor lock-in. By using PaaS that have alternatives elsewhere in the market will avoid lock-in. Being able to extract your business data and business rules from a PaaS is key to avoiding lock-in. Most cloud providers offer database, web server, and file server platforms. While migrating from one to another may not be completely painless, migration tools and APIs exist to allow for this possibility.
