In early 2020 the PlaceExchange SRE team was challenged to build support for the company's first gRPC application that would run on Amazon's Elastic Kubernetes Service (EKS). Our usage of third-party geocoding APIs was beginning to exceed the cost of implementing our own service, and so we decided to build one with a gRPC interface. We had already operated EKS for several months with RESTful services and felt confident in our ability to deliver a platform capable of hosting multiple instances of the API for our developers to work concurrently. Given our extensive use of per-developer environments (namespaces) and adherence to the infrastructure as code model, it seemed natural to extend this pattern to support gRPC services.

Cloud computing is becoming more and more of a household name, with even the most conservative fields of business figuring out how to make the best use of it. Cloud computing usually starts with running a private cloud solution on premises before venturing onto the public cloud. Of course, the cloud is not a single uniform being. It may come from different providers, Amazon Web Services, Google Cloud Platform, and Microsoft Azure being the biggest players here. Or it may come with different visibility and hosting, that is, public (resides with the provider), private (self-hosted), or hybrid (which uses a bit of both). And the cloud can use different tools and APIs for management as well.

395. Rethinking Programming: From Code to Cloud

Earlier, developers simply wrote their program, built it and ran it.

However, these deployment options are not part of the programming experience for a developer. The developer has to write code in a certain way to work well in a given execution environment, and removing this from the programming problem isn’t good.
