A company has developed a non-production application that is composed of multiple microservices for each of the company's business units. A single development team maintains all the microservices.

The architecture also uses a MySQL database that the company hosts on an Amazon EC2 instance. The company needs to ensure that the application is secure and available globally. Which solution will meet these requirements with the LEAST operational overhead?
