Microservicin’ ain’t easy, but it’s necessary. Breaking your monolith down into smaller pieces is a must in a cloud native world, but it doesn’t automatically make everything easier. Some things actually become more difficult. An obvious area where it adds complexity is communications between services; visibility into service to service communications can be hard to achieve, but is critical to building an optimized and resilient architecture. The idea of monitoring has been around for a while, but observability has become increasingly important in a cloud native landscape.…
At Aspen Mesh we love gRPC. Most of our public facing and many internal APIs are built using gRPC. To give you a brief background in case you haven’t heard about gRPC (would be really difficult with gRPC’s belle of the ball status), it is a new, highly efficient and optimized Remote Procedure Call (RPC) framework. It is based on the battle tested protocol buffers serialization format and HTTP/2 network protocol.…
This is the third in a blog series covering how we got to a service mesh, why we decided on the type of mesh we did and where we see the future of the space. If you’re struggling to manage microservices as architectures continue to become more complex, there’s a good chance you’ve at least heard of service mesh. For the purposes of this blog, I’ll assume you’re familiar with the basic tenets of a service mesh but check out the Istio page (the mesh we are building on top of) if you’re not yet up to speed.…
Note: This is the second in a series of posts, focused on the software architecture aspects of service mesh. To learn more about how we got here, check out The Path to Service Mesh. If you are building your software and teams around microservices, you’re looking for ways to iterate faster and scale flexibly. A service mesh can help you do that while maintaining (or enhancing) visibility and control. In this blog, I’ll talk about what’s actually in a Service Mesh and what considerations you might want to make when choosing and deploying one.…
This is a quick blog on how we use AWS services from inside of an Istio Service Mesh. Why does it matter that you’re inside the mesh? Because the service mesh wants to manage all the traffic in/out of your application. This means it needs to be able to inspect the traffic and parse it if it is HTTP. Nothing too fancy here, just writing it down in case it can save you a few keystrokes.…
When we talk to people about service mesh, there are a few questions we’re always asked. These questions range from straightforward questions about the history of our project, to deep technical questions on why we made certain decisions for our product and architecture. To answer those questions we’ll bring you a three-part blog series on our Aspen Mesh journey and why we chose to build on top of Istio.…
Building microservices is easy, operating a microservice architecture is hard. Many companies are successfully using tools like Kubernetes for deploys, but they still face runtime challenges. This is where the service mesh comes in. It greatly simplifies the managing of containerized applications and makes it easier to monitor and secure microservice-based applications. So what are the top 5 reasons to use a supported service mesh? Here’s my take.…
Everybody loves tracing! Am I right? If you attented KubeCon (my bad, CloudNativeCon!) 2017 at Austin or saw any of the keynotes posted online, you would have noticed the recurring theme explaining the benefits of tracing. Istio and service mesh were hot topics and many sessions discussed how Istio provides distributed tracing out of the box making it easier for application developers to integrate tracing into their system. Indeed, a great benefit of using service mesh is getting more visibility and understanding of your applications.…
AspenMesh provides a supported distribution of Istio, which means that we need to be able to test and release bugfixes even if they are out-of-cadence with the upstream Istio project. To do this we’ve developed our own build and test infrastructure. Now that we’ve got many of these pieces up and running, we figured some parts might be useful if you are also interested in CI for Istio but not committed to Circle CI or GKE.…
Today we are very excited to introduce Aspen Mesh, an enterprise service mesh built on the open source project Istio. After talking to development and operations teams it became clear that microservices are great for development velocity, but the complexity and risk in these architectures lies in the service-to-service communication that microservices depend on. We have taken an application first approach to provide a communication fabric for microservices, called a service mesh.…
