Java SE is ideal for building lightweight microservices and those services are increasingly being deployed to the cloud. Cloud platforms are attractive deployment targets due to their high availability, affordability, ease of management, and access to services like object storage, messaging, and databases. And when well architected, Cloud Java apps exhibit a number of qualities like portability, updatability, configurability, composability, and scalability.

runnable shell script to start your application
• Integrate with Oracle Cloud and external services
– Connect to the database, call REST APIs, etc
