Service mesh technology, such as Istio integrated within VMware Cloud Foundation (VCF) 9.0 and vSphere Kubernetes Service (VKS), is designed to solve the complexities of microservices communication. Two of the most fundamental capabilities provided by a service mesh are Service discovery and Connection encryption. In a dynamic Kubernetes environment where pods are frequently created and destroyed, Service discovery allows microservices to locate and communicate with each other automatically without requiring hardcoded IP addresses or manual configuration changes. The service mesh control plane maintains a real-time registry of all active service instances and their locations.
