Service Mesh (envoy proxy) is a dedicated infrastructure layer in microservices architecture, that allows you to transparently add capabilities like observability, traffic management, and security, without adding them to your own code. The problem is that Service Mesh is fully supported on mainstream platforms only (e.g. x86 and ARM). In my presentation I'm going to share my experience of enabling Service Mesh on IBM s390x big-endian platform. I will talk about the Service Mesh code and build tools differences between s390x and x86 implementations. I'll also explain how we enabled some features, that were previously supported on x86 platform only (e.g. WASM and LUA extensions, BoringSSL library replacement).
