What is Platform Engineering
https://tag-app-delivery.cncf.io/whitepapers/platforms/
A platform for cloud-native computing is an integrated
collection of capabilities de
fi
ned and presented according
to the needs of the platform’s users. It is a cross-cutting
layer that ensures a consistent experience for acquiring and
integrating typical capabilities and services for a broad set
of applications and use cases.

What is Platform Engineering
A digital platform is a foundation of self-service APIs, tools,
services, knowledge and support which are arranged as a
compelling internal product. Autonomous delivery teams
can make use of the platform to deliver product features at
a higher pace, with reduced co-ordination.

Modular Monolith
Almost all the cases where I've heard of a system that was built
as a microservice system from scratch, it has ended up in serious
trouble. ...
you shouldn't start a new project with microservices, even if
you're sure your application will be big enough to make it
worthwhile.

microservices is not without its challenges, some of which

Cloud Run
Cloud Run is a managed compute
platform that enables you to run
containers that are invocable via
requests or events.
Cloud Run is serverless: it abstracts
away all infrastructure management...

https://learn.microsoft.com/en-us/dotnet/architecture/microservices/architect-microservice-container-applications/
direct-client-to-microservice-communication-versus-the-api-gateway-pattern#what-is-the-api-gateway-pattern
the API gateway sits between the client apps and the
microservices. It acts as a reverse proxy, routing requests
from clients to services. It can also provide other cross-
cutting features such as authentication, SSL termination,
and cache.

Envoy
https://www.envoyproxy.io/docs/envoy/v1.34.1/intro/what_is_envoy
Envoy is an L7 proxy and communication bus
designed for large modern service oriented
architectures. The project was born out of the
belief that:
The network should be transparent to
applications. When network and application
problems do occur it should be easy to
determine the source of the problem.
