CQRS and Event Sourcing (or, more in general, applications using events as their basic information block) are by no means new kids on the block, yet a lot can be told about how to use cloud platforms to unleash their power without having costs soaring.
The ingredients list is quite simple: an event store, an event dispatcher, read model(s) and computing options to run back-end services. Picking up technologies in a cost savvy way, though, isn’t trivial due to the amount of viable options: should we go PaaS (e.g.: CosmosDB/DynamoDB, AppService, ASB/SQS) or IaaS? CosmosDB/DynamoDB or Mongo? Where do containers fit in this context?
