>those other ecosystems still need Kubernetes, Kafka, Redis and GRPC, to get by And what makes Elixir not need Kafka, Redis or GRPC? Instead of Redis, you could use ETS for caching. But once you have 2+ instances of your app, you will need to have a centralized caching mechanism, otherwise, each instance will have its own ETS with its own memory, not sharing anything. Unless you decide to use Distributed Erlang and connect all the nodes of your application, which comes with a lot of trouble. Much easier to just use Redis. And lets say you have multiple teams, each team has its own service(built with Elixir), and you need to have some async communication between those services. What native Elixir solution would you use instead of Kafka? Same for GRPC. What's the alternative? Connecting all the nodes and using Erlang message-passing? |
Just say no to Kafka.
