Abstract

Service Meshes are fast becoming ubiquitous in cloud-native infrastructure, and are applicable to traditional environments as well. They involve running a small reverse proxy alongside each daemon, which does traffic management on its behalf - in this session we’ll be using the most popular mesh, Istio, based on the modern Envoy proxy.

To the platform engineer, meshes provide a more advanced and configurable network, with built-in security and unparalleled observability. To the software engineer, they offer features for service discovery, resiliency, and debugability. But Service Meshes can be daunting; difficult to understand and hard to use.

This practical workshop will kick-start your Service Mesh journey. We’ll use a managed EKS cluster and a one-click Istio add-on from the marketplace, getting us started in no time. We’ll deploy some microservices to explore Istio’s features, like automatic timeouts and retires. We’ll also look at the powerful observability features, automatic service-to-service mutual TLS, and more!

In between the exercises I’ll present some theory about how Service Meshes work, so you have the full picture of what’s going on under the hood. Armed with this knowledge and your practical experience from the day, you’ll be well-equipped to continue your Service Mesh journey.

Key takeaways

• Knowledge and experience that will let you decide whether a Service Mesh, and Istio in particular, is right for your environment
• Hands-on experience with Istio’s key features, which you can explore further and demo to others
• An understanding of how a Service Mesh works with your microservices, and how to configure both to compliment each other
