A Microservice, in contrast to SOA Service, can initiate its work based on a schedule with no other elements of the Application (App) being aware of …

Published on March 3, 2019 Fault tolerance requirement was known for a long time before Microservices were defined. This requirement has surfaced again because when working with relatively small applications or components like Microservices, it is much easier to observe fault tolerance and it replicates at a higher scale than when working with monolith applications. …

2014 Motivation Current Principles of Service Orientation (SO) were formulated about 15 years ago when Service-Oriented Architecture (SOA) fought its way up into the mainstream of enterprise IT. They are widely known from publications of Thomas Erl 1,2 where the vocabulary of SO was compromised for the sake of mass adoption of Web Service technology. …
