You’ve been hearing about service mesh. You have an idea of what it does and how it can help you manage your microservices. But what happens once you have one? How do you get as much out of it as you can?

Let’s start with a quick review of what a service mesh is, why you would need one, then move on to how to get the most out of your service mesh.

What’s a Service Mesh?

  1. A transparent infrastructure layer that sits between your network and application, helping with communications between your microservices

  2. Could be your next game changing decision

A service mesh is designed to handle a high volume of service-to-service communication using application programming interfaces (APIs). It ensures that communication among containerized application services is fast, reliable and secure. The mesh provides critical capabilities including service discovery, load balancing, encryption, observability, traceability, authentication and authorization, and write-once, run anywhere policy for microservices in your Kubernetes clusters.

Service meshes also address challenges that arise when your application is being consumed by an end user. The first key capability is monitoring the health of services provided to the end user, and then tracing problems with that health quickly to the correct microservice. Next, you’ll need to ensure communication is secure and resilient.

When Do You Need a Service Mesh?

We’ve been having lots of discussions with people spread across the microservices, Kubernetes and service mesh adoption curves. And while it’s clear that many enterprise organizations are at least considering microservices, many are still waiting to see best practices emerge before deciding on their own path forward. That means the landscape changes as needs are evolving. 

As an example, more organizations are looking to microservices for brownfield deployments, whereas – even a couple of years ago – almost everyone only considered building microservices architectures for greenfield. This tells us that as microservices technology and tooling continues to evolve, it’s becoming more feasible for non-unicorn companies to effectively and efficiently decompose the monolith into microservices. 

Think about it this way: in the past six months, the top three reasons we’ve heard people say they want to implement service mesh are:

  1. Observability – to better understand the behavior of Kubernetes clusters 
  2. mTLS – to add cluster-wide service encryption
  3. Distributed Tracing – to simplify debugging and speed up root cause analysis

Gauging the current state of the cloud-native infrastructure space, there’s no doubt that there’s still more exploration and evaluation of tools like Kubernetes and Istio. But the gap is definitely closing. Companies are closely watching the leaders in the space to see how they are implementing and what benefits and challenges they are facing. As more organizations successfully adopt these new technologies, it’s becoming obvious that while there’s a skills gap and new complexity that must be accounted for, the outcomes around increased velocity, better resiliency and improved customer experience mandates that many organizations actively map their own path with microservices. This will help to ensure that they are not left behind by the market leaders in their space.

Getting the Most Out of Your Service Mesh

Aspen Mesh - Getting the Most Out of Your Service MeshIn order to really stay ahead of the competition, you need to know best practices about getting the most out of your service mesh, recommendations from industry experts about how to measure your success, and ways to think about how to keep getting even more out of your technology.

But what do you want out of a service mesh? Since you’re reading this, there’s a good chance you’re responsible for making sure that your end users get the most out of your applications. That’s probably why you started down the microservices path in the first place.

If that’s true, then you’ve probably realized that microservices come with their own unique challenges, such as:

  • Increased surface area that can be attacked
  • Polyglot challenges
  • Controlling access for distributed teams developing towards a single application

That’s where a service mesh comes in. Service meshes are great at solving operational challenges and issues when running containers and microservices because they provide a uniform way to secure, connect and monitor microservices. 

TL;DR a good service mesh keeps your company’s services running they way they should, giving you the observability, security and traffic management capabilities you need to effectively manage and control containerized applications so you can focus on adding the most value to your business.

When Service Mesh is a Win/Win

Service mesh is an application that can help entire organizations work together for better outcomes. In other words, service mesh is the ultimate DevOps enabler.

Here are a few highlights of the value a service mesh provides across teams:

  • Observability: take system monitoring a step further by providing observability. Monitoring reports overall system health, while observability focuses on highly granular insights into the behavior of systems along with rich context
  • Security and Decreased Risk: better secure the services inside your network and quickly identify any compromising traffic entering your clusters
  • Operational Control: allow security and platform teams to set the right macro controls to enforce access controls, while allowing developers to make customizations they need to move quickly within defined guardrails
  • Increase Efficiency with a Developer Toolbox: remove the burden of managing infrastructure from the developer and provide developer-friendly features such as distributed tracing and easy canary deploys 

What’s the Secret to Getting the Most Out of Your Service Mesh?

There are a lot of things you can do to get more out of your service mesh. Here are three high level tactics to start with:

  1. Align on service mesh goals with your teams
  2. Choose the service mesh that can be broadly deployed to address your company’s needs
  3. Measure your service mesh success over time in order to identify and make improvements
