52. A recently created startup built a three-tier web application. The front end nas static content. The application layer is based on mtcroservtces User data is stored as JSON documents that need to be accessed with low latency. The company expects regular traffic to be tow during the first year with peaks in traffic when it publicizes new features every month. The startup team needs to minimize operational overhead costs
