Microservices

Characteristics of Microservices

1. Componentization via services
   replace independently, upgrade independently

2. Organized around business capabilities
   team orgination thing

3. Products not Projects

1. Smart endoints and dumb pipes
   pipe just for delivery message

SOA - ESB - route message , translate message
Microservices - pipe must be dumb, endpoint/application must be smart.

1. Decentralized Governance
2. Decentralized Data Management
   no central group, miniimum connectivity

each service gets its own data storage and does not share that data directly with anybody else.

all sharing has to go throught the services that wrap the data

1. Infrastructure Automation
   CI CD.

2. Design for failure
   Chaos monkey

handle failure.
