While the modern meshes aren't interchangeable, they do generally offer the same broad table-stakes features to add security, reliability, and observability to applications.

In this Linkerd Day talk, you'll join the engineers responsible for recommending a mesh to learn how they went about making their decision, starting with their primary use case of mTLS and metrics, continuing into performance and time to production, and finishing with how they viewed support and maintenance costs and how they balanced wants and needs when making their decision (Linkerd, of course!).
