Micro is an operating system built for the cloud. It addresses the key requirements for building services in the cloud. It leverages the microservices architecture pattern and provides a set of services which act as the building blocks of a platform. Micro deals with the complexity of distributed systems and provides simpler programmable abstractions to build on.

Micro is built as a microservices architecture and abstracts away the complexity of the underlying infrastructure. It is composed as a single logical server to the user but decompose that into the various building block primitives that can be plugged into any underlying system.

The server is composed of the following services.

API - HTTP Gateway which dynamically maps http/json requests to RPC using path based resolution
Auth - Authentication and authorization out of the box using jwt tokens and rule based access control.
Broker - Ephemeral pubsub messaging for asynchronous communication and distributing notifications
Config - Dynamic configuration and secrets management for service level config without the need to restart
Events - Event streaming with ordered messaging, replay from offsets and persistent storage
Network - Inter-service networking, isolation and routing plane for all internal request traffic
Proxy - An identity aware proxy used for remote access and any external grpc request traffic
Runtime - Service lifecycle and process management with support for source to running auto build
Registry - Centralised service discovery and API endpoint explorer with feature rich metadata
Store - Key-Value storage with TTL expiry and persistent crud to keep microservices stateless
