Google Cloud has announced the launch of Service Extensions plugins for Application Load Balancers, allowing you to run your custom code at the edge of the network. This means you can tailor load balancers to meet your specific business needs, whether adding or manipulating headers, enhancing security, custom logging, exception handling, or HTML rewriting. Google Cloud manages the underlying infrastructure while you focus on your business logic. Service Extensions currently support the traffic extension for the global external Application Load Balancer and the route and traffic extensions for the cross-region internal load balancer. Interestingly, Service Extensions are built on WebAssembly (Wasm), offering near-native execution speed, fast startup time, support for a variety of programming languages, cross-platform portability, and security protections. I believe this feature will be particularly useful for businesses requiring a high degree of customization for their load balancers, such as those in e-commerce, gaming, or financial services. By being able to run custom code, companies can improve the performance, security, and user experience of their applications.
