Micro Is An Ecosystem
Framework
Toolkit
Pluggable Layers
Plugins Everywhere
message broker
encoding/decoding
transport
metrics
Nearly every choice in micro has a sane default and many optional replacements.
Abstractions
Broker
Transportation for events. Micro can emit events, and interested services can consumethem and react.
HTTP (default)
Google PubSub
Kafka
MQTT
NATS
NSQ
RabbitMQ
Redis
Amazon SQS
Codec
Encoding of messages before transport.
bsonrpc
jsonrpc
jsonrpc2
mercury
msgpackrpc
protorpc (default)
Registry
Service Discovery
consul (default)
etcd 2 or 3
Eureka
gossip
kubernetes
mdns (Multicast DNS)
NATS
zookeeper
Selector
How clients choose an instance of a service.
blacklist -- circuit breaker pattern for selecting service instances
cache -- random hash choice
label -- priority based labels, use for prioritized selection
named -- use with message bus/queue transport
static -- for use with upstream balancing
Transport
Physical transport of messages.
grpc
http (default)
NATS
RabbitMQ
TCP
UTP (UDP variation of BitTorrent protocol)
Batteries Included
All of these choices can be overwhelming, but Micro defaults are perfect for development.
In production, you can change any of the options without changing your code.
