February 2021 Summaries

Telepresence is a CNCF sandbox project that enables developers to connect their local development machine to a remote cluster via a two-way proxying mechanism, allowing them to develop services locally while testing integrations with dependent services or data stores running in the remote cluster. This technology accelerates the development workflow and mitigates integration issues by mirroring the live production environment. Telepresence can be used for integration testing, enabling developers to make changes and see them reflected when interacting with their Kubernetes environment, query services only exposed in their cluster's network, and set breakpoints in their IDE to investigate bugs.

HTTP/3 is a new evolution of the Hypertext Transfer Protocol (HTTP) designed to reduce latency and increase resilience over lossy networks. It uses QUIC and UDP instead of TCP, providing low-latency and resilient connections for the World Wide Web. HTTP/3 has several benefits compared to HTTP/2, including increased resilience with QUIC's fast "Zero Round Trip Time Resumption" (0-RTT) reconnections and reduced latency when streaming data. Implementing HTTP/3 in applications is complex without an ingress, proxy, or API gateway that fully supports the final HTTP/3 RFC specification. However, many organizations are adopting HTTP/3 using Envoy Proxy-powered ingresses or API gateways to provide secure and efficient connections for their users.
