Q&A with Brian Jimerson, Solutions Architect and Istio and multi-cloud deployment expert

I recently had a sit down with one of our Aspen Mesh expert Istio engineers to answer some questions that I hear from customers as they start their multi-cluster Istio journey. If your organization already has a series of disparate single-cluster Istio deployments, real benefits can be achieved by connecting them together to create a multi-cluster service mesh. 

Here are some of the highlights of my conversation with Brian Jimerson, one of our seasoned solution engineers whose experience runs deep optimizing Fortune 2000 enterprise architectures. I wore the hat of a customer exploring the ways moving to a multi-cluster environment might impact performance.

Q: I have stringent SLOs and SLAs for my cloud applications. How can I work to meet these?

Brian: Having multiple Kubernetes clusters in different fault zones can help with disaster recovery scenarios. Using a multi-cluster service mesh configuration can simplify cutover for an event.

Q: As an international company, I  have data privacy requirements in multiple countries. How do I ensure that data is stored in a private manner?

Brian: Using Aspen Mesh’s locality-based routing can ensure that customers are using a cluster in their own country, while reducing latency. This can help ensure that private data does not leave the user’s country.

Q: I need the ability to quickly scale workloads and clusters based on events. How can I do this in a way that’s transparent to customers?

Brian: Using a multi-cluster service mesh can help to scale clusters out and in without interruption to users. A multi-cluster service mesh acts like a single cluster service mesh to services, so communication patterns remain unchanged.

Q: I have compliance requirements for workloads, but they also need to be accessed by other applications. How do I do this?

Brian: Using a multi-cluster service mesh, you can operate compliance workloads in a hardened cluster, and securely control traffic to those workloads from another cluster.

 

I encourage you to read the full paper, Advantages of Going Multi-cluster Using Istio — and Best Practices to Get There. The move to a multi-cluster environment is complex and there are many things to consider. Working with Brian and our Aspen Mesh Solutions team, I’ve written a a deep-dive paper that spells out both the advantages and things to look out for when evaluating a move to multi-cluster. There are some disadvantages you have to weigh, and I detail those along with the expected performance improvements that come with deploying a multi-cluster service mesh. In this paper I lay out the benefits and important considerations when considering migrating to a multi-cluster that leverages Istio.
