In short, with Prefect Cloud, you have full control over your
execution environment (your agents, your task run environment such as Dask clusters), and Prefect Cloud is handling all services related to the
orchestration environment including the GraphQL API, database, hosting the UI, managing logs, Auth, RBAC, providing additional KV Store and Secrets backend, and making sure it all works reliably.
