SOA Microservices

Smartpipes,dumbendpoints Simplepipes,smartendpoints

Centralised governance (ESB) Minimal governance

Proprietarystandards Openstandards

Services provide myriadfunctions Services aresinglepurposed

Distributedmonoliths? Bewareofthemicroliths!

MSA-SummitThe Death Star

• Single-purpose

• ConnectonlythroughAPIs

• ConnectoverHTTPS

• Largely“blackboxes”toeachother

• “DevOps”

MSA-SummitLots of folk are doing it, and talking about it
