Deepa Kalani and Ramiro Salas from the VMware team spoke at SpringOne 2020 Conference last week about the Tanzu Service Mesh (TSM) product and how it helps developers with Global Namespaces to implement access control and security policies, as well as visualization tools to show application-centric metrics.

A service mesh decouples services from having to know about the network and helps developers to focus on business logic. A typical service mesh can provide:

• Service discovery
• Weighted routing (for A/B deployments)
• Mutual TLS based authentication (including certificate rotation)
• Advanced telemetry for in-depth observability
• Fault injection and retries
• Circuit breakers

Today developers are working on cloud native applications and need to deal with monolithic apps, microservices, and serverless functions (FaaS) based models. A Service Mesh must be able to support all of the corporate developer use cases. It also needs to be transparent and it needs to be out of the way, so developers can be productive by focusing on application functionality and business logic.
