A leading open source reverse proxy and load balancer, Traefik Proxy, is adding more cloud native support.
Reverse proxy and load balancing software has been vital for connecting backend services with frontend interfaces since the days when everything was written as Linux, Apache, MySQL, Perl/PHP/Python (LAMP) stacks.
Then along came cloud native computing, and things got much more complex. As Emile Vauge, Traefik’s creator, said previously in The New Stack, “Traditional reverse proxies were not well-suited for these dynamic environments.” Now, the open source Traefik Proxy, which has been successfully addressed for almost a decade, is expanding its cloud native support even further.
On Wednesday, Traefik Labs, the project’s parent company, introduced the first Release Candidate of Traefik Proxy v3. This new version now supports WebAssembly (Wasm), OpenTelemetry, and Kubernetes Gateway API.
WebAssembly support inclusion may prove a game-changer. Besides offering high-performance, language-agnostic capabilities for serverless and containerized applications, Traefik’s support provides Wasm with a larger potential market.
“This is a major step towards a low friction extensibility story for Traefik as it brings broader plugins into its growing ecosystem while providing a great developer experience. with plugins that can be written in different languages and compiled directly into Wasm,” said Jose Carlos Chavez, co-leader of the Open Worldwide Application Security Project (OWASP) Coraza project, Web Application Firewall, in a statement.
Integrating OpenTelemetry, which standardizes the format for logging metrics and tracing with OpenTelemetry protocol (OTLP), will provide users with improved visibility into their applications.
Since the OpenTelemetry Collector also supports older data collection programs such as Prometheus and Zipkin, this is also a way that Traefik will expand its usability. And, of course, this will aid network administrators and developers with troubleshooting and performance optimization.
“Our company has been using Traefik extensively within many Kubernetes production deployments,” Jesse Haka, a cloud architect at Elisa, a Finnish telecommunications company, in a statement. Haka is a Traefik Wasm and OpenTelemetry open source contributor.
“We are eager to deploy this new major release of Traefik to unlock Wasm and OpenTelemetry support, which are key technologies that open new possibilities for us.”
Finally, Traefik Proxy’s new support for the Kubernetes Gateway API represents a significant step toward simplifying the management and configuration of routing within Kubernetes environments. This added Gateway API support delivers a standardized way to manage and configure Layer 4 and Layer 7 Kubernetes routing.
Even without these improvements, Traefik Proxy has long been a cornerstone in the cloud native API gateway landscape, with 3 billion downloads to date.
Another plus for the many people already using Traefik is that Traefik Labs prioritizes a smooth transition from Traefik Proxy v2 to v3, This ensures backward compatibility and a progressive adoption path for the new syntax.
In a statement, Vauge, Traefik Labs’ CTO, emphasized the importance of application proxies in today’s cloud native world: “Application proxies are pivotal in managing network traffic, ensuring high availability and security. With v3, Traefik Proxy becomes an even more essential component of the cloud native application stack, offering unparalleled accessibility and power.”
