There are several cloud architecture types. Each architecture type has its unique benefits and drawbacks. The public cloud offers scalability and agility, private cloud solutions offer security, and the hybrid cloud combines the best of both worlds. Organizations must assess their needs to determine which architecture best suits their specific requirements.

Netflix began its rise to the top on a monolithic architecture.  In 2008 Netflix experienced an outage that impacted over 8 million customers. The hit to revenue and reputation set the company in a different direction. The organization decoupled its technology and moved to the AWS cloud under a microservices architecture.

Dropbox began its rise to the top on AWS cloud architecture. In 2015 the organization realized it was not able to scale with customer demand and began a journey away from the cloud to private data centers.

There is no such thing as a cloud solution. There are cloud trade-offs.
