Loose coupling is a key architectural principle for ensuring a range of non-functional properties. It is extensively and successfully used in message queuing since many decades. In this talk we will show that service computing (in both styles, i.e. SOA-based as well as
REST-based) is enabling loose coupling too. Based on this, the talk will argue why microservices is nothing really new. Best practices (aka patterns) will be discussed that help building loosely coupled applications for the cloud.
