Google Cloud has announced Service Extensions plugins for Application Load Balancers, allowing users to run custom code in a fully managed environment.
The plugins support various use cases including header addition, manipulation, security, custom logging, exception handling, and HTML rewriting.
Service Extensions plugins run at the edge of Google's globally distributed network and leverage WebAssembly (Wasm) for near-native execution speed.
Google Cloud provides a massively multi-tenant compute platform for Service Extensions plugins, allowing scalability and low latency.
