Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

A Comprehensive Guide to API Gateways, Kubernetes Gateways, and Service Meshes
The Service Mesh Interface (SMI) specification was created to solve this portability issue.

Service Mesh Use Cases
> I suspect if a Service Mesh is ultimately shown to have broad value, one will make it's way into the K8S core
I'm not so sure. I suspect it'll follow the same roadmap as Gateway API, which it already kind of is with the Service Mesh Interface (https://smi-spec.io/)

Service Mesh Considerations
It is very common that a service mesh deploys a control plane and a data plane. The control plane does what you might expect; it controls the service mesh and gives you the ability to interact with it. Many service meshes implement the Service Mesh Interface (SMI) which is an API specification to standardize the way cluster operators interact with and implement features.

Kubernetes: Cross-cluster traffic scheduling - Access control
Before we start, let's review the SMI Access Control Specification. There are two forms of traffic policies in osm-edge: Permissive Mode and Traffic Policy Mode. The former allows services in the mesh to access each other, while the latter requires the provision of the appropriate traffic policy to be accessible.

Announcing osm-edge 1.1: ARM support and more
osm-edge is a simple, complete, and standalone service mesh and ships out-of-the-box with all the necessary components to deploy a complete service mesh. As a lightweight and SMI-compatible Service Mesh, osm-edge is designed to be intuitive and scalable.

Kubernetes State Of The Union — KubeCon 2019, San Diego
I started on Monday, attending ServiceMeshCon2019. My guesstimate is that about 1000 people attended it. I believe Service Mesh is playing such a crucial role in scaling cloud native technologies that large scale cloud-native deployments may not be possible without service mesh. Just like you cannot really succeed in deploying a microservices based application without a microservices orchestration engine, like Kubernetes, you cannot scale the size and capacity of a microservices-based application without service mesh. That’s what makes it so compelling to see all the service mesh creators — Istio, Linkerd, Consul, Kuma — and listen to them. There was also a lot of discussion of SMI (Service Mesh Interface) — a common interface among all services mesh. The panel at the end of the day included all the major service mesh players, and some very thought provoking questions were asked and answered by the panel.

Introducing the Cloud Native Compute Foundation (CNCF)
In the episode with Annie, she gave a great overview of the CNCF and a handful of projects that she's excited about. Those include Helm, Linkerd, Kudo, Keda and Artifact Hub. I gave a bonus example of the Service Mesh Interface project.

Kubernetes: Cross-cluster traffic scheduling - Access control
Flomesh open source service mesh osm-edge is based on an implementation of the SMI (Service Mesh Interface) standard. SMI defines specifications for traffic identification, access control, telemetry, and management. In the previous article Kubernetes: Multi-cluster communication with Flomesh Service Mesh we covered the background, motivations, and goals of Kubernetes multi-cluster and part 2 Kubernetes: Multi-cluster communication with Flomesh Service Mesh (Demo) we demonstrated a detailed demo of how to use FSM in a multi-cluster environment and how to schedule policies for traffics.

osm-edge: Using access control policies to access services with the service mesh
This article will focus on the second approach, which allows support for fine-grained access control on who can access services within the service mesh. This feature is newly added and available in release 1.2.0 osm-edge v1.2.0.

Benchmarking osm and osm-edge data planes
osm-edge is built on top of Open Service Mesh (OSM) v1.1.0 codebase and is a lightweight service mesh for resource-sensitive cloud environments and edge computing scenarios. It uses osm as the control plane and Pipy as the data plane and features high performance, low resources, simplicity, ease of use, scalability, and compatibility (x86/arm64 support).

Announcing osm-edge 1.1: ARM support and more
The evolution of Kubernetes to the edge side solves the difficulties of edge computing to a certain extent, especially against fragility; while the development of service mesh to the edge side focuses on network issues in edge computing, against network fragility, as well as providing basic network support for distributed, such as fault migration. In practice, container platforms, as today's de facto quasi-standard means of application delivery, are rapidly evolving to the edge side, with a large number of releases targeting edge features, such as k3s; but service mesh, as an important network extension for container platforms, are not quickly keeping up with this trend. It is currently difficult for users to find service mesh for edge computing scenarios, so we started the osm-edge an open source project with several important considerations and goals, namely
