Return to Istio, CNCF Glossary, Service Mesh

• Description: Istio is an open source service mesh microservices platform to connect microservices, manage microservices, and secure microservices.
• Documentation: https://istio.io/docs
  • Provide an Istio glossary of the top 40 Istio concepts sorted by the most commonly used. For each concept include a brief description and the URL for the Istio official documentation. Answer using MediaWiki format.

Creating a glossary for the top 40 Istio concepts involves highlighting the core features, components, and practices central to Istio, a service mesh that provides a way to control how microservices share data with one another. Below is an example glossary in MediaWiki format, focusing on the key Istio concepts. Since specific URLs for each concept's documentation within the Istio official documentation might vary and be updated, I'll provide a general link to the Istio documentation where you can search for the most current and detailed information on each concept.

This glossary provides an overview of the top 40 Istio concepts, offering insights into the functionalities and components that define the Istio service mesh. Each entry includes a brief description and a link to the official Istio documentation for further exploration.
