The document discusses connectivity and service meshes. It describes how systems have evolved from monoliths to microservices and the rise of service meshes to manage inter-service communication. It contrasts API gateways with service meshes, noting that service meshes use decentralized sidecars to handle traffic policies between applications within a mesh, while API gateways provide centralized ingress for traffic.
