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.

Applications built on monolithic/ 3-tier/ n-tier architecture often fail to meet the market demands in terms of scaling and performance. This is generally attributed towards the inflexible nature of these architectures, where code base becomes unmanageable due to various reasons - like addition of new features, identifying dependencies, and side effects that could crop up due to scaling, etc. In these environments, adopting new technologies and making changes take a long time. The bottom line is that they are less agile and ancient.

This article helps you manage your cluster resources properly, especially in an autoscaling environment.

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.

Enterprises around the world are waking up to the containers and Kubernetes trend. There are numerous benefits of delivering an application as container packages to Kubernetes but at the same time, the process of app containerization and the subsequent app deployment to Kubernetes can hit many roadblocks. Since the idea of using Kubernetes and containers for app delivery is fairly recent, the transition from traditional delivery systems to these modern delivery systems is a bumpy ride.

Earlier, developers simply wrote their program, built it and ran it. Today, developers need to also think of the various ways of running it whether it be as a binary on a machine (virtual most likely), by packaging it into a container, by making that container a part of a bigger deployment (K8s) or by deploying it into a serverless environment or a service mesh. 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.

Crossplane is the next step in the evolution of software infrastructure; provisioning, delivery and maintenance.
