• The Future of Istio is sidecar-less

  Every service mesh, including Istio, uses a sidecar proxy as its data plane. With this pattern, a mesh can intercept and enhance the capability of networking communication on behalf of an application. However, and unfortunately, this sidecar deployment pattern comes with a price to pay in terms of operations, complexity, and performance. With the advent of eBPF in modern operating systems, and some coordination with the Linux networking capabilities, we can look forward to improvements in service mesh architecture including moving away from a sidecar approach to a more transparent approach. In this talk we dig into the future of Istio, which I work on, to show how Istio can be run in a sidecarless mode.

• Packaging vcluster with Carvel

  Jump in with Leigh Capili for an adventure into the fun components and quirks of vcluster the awesome open-source project from Loft. This project is very exciting because it enables a multi-tenancy model that empowers platform builders to implement controls and features while also enabling end-users to have access and freedom within their virtual-cluster boundary.

  Expect Leigh to bring his hacking spirit and obsession with developer experience along! Flux now supports OCI sources, and Carvel has a new package creation workflow ;) (kctrl package). See you for the demo!
