Application Topology/Architecture and Management (e.g. service

modeling, application packaging)

Release management

QA planning and automation tools

Performance Monitoring and Analysis/Log Event Management

Loosely coupled services

“ The only communication allowed [at Amazon] is via service interface calls over the network.”– Steve Yegge, Google, Oct 2011,

paraphrasing Jeff Bezos memo

https://plus.google.com/+RipRowan/posts/eVeouesvaVX

34

Loosely coupled teams

“ One of the biggest changes is that we no longer have an official ‘architecture’ team. Instead, we have made ‘architecture’ an ‘ingredient’ on each of our teams.”

Container orchestration is limited (∴ adoption immature)
