Decision Making ConsiderationsAgenda

"Microservicesis asoftware architecture stylein which complex applications are composed ofsmall, independent processescommunicating with each other using language-agnostic APIs."

fromWikipediaWhat is a Microservice?

Event basedAPIDiscreet tasks/services/processesIndependently scalable

Microservice Attributes

"serverless computing is a cloud computing code execution model in which the cloud provider fully manages starting and stopping virtual machines as necessary to serve requests, and requests are billed by an abstract measure of the resources required to satisfy the request, rather than per virtual machine, per hour."

from WikipediaWhat is Serverless?

Code focusedNo servers to manageNo EC2 No manual scaling or server provisioningNo idle resourcesNo SSH (or RDP)
