ELIoT: Distributed Programming for the Internet of Things

by Sergio De Simone on  Jul 16, 2015

ELIoT (Extensible Language for the Internet of Things) is a simple and small programming language aiming to make distributed programming easier. A program in ELIoT may appear as a sigle program, but it actually runs on different computers, so, e.g., a variable or function declared on one computer is transparently used on another.

Stefan Tilkov: Skip the Monolith, Start with Microservices

by Jan Stenberg on  Jun 10, 2015 2

During the last months Martin Fowler among others have claimed that a microservices architecture should always start with a monolith, but Stefan Tilkov is convinced this is wrong, building a well-structured monolith with cleanly separated modules that later may be pulled apart into microservices is extremely hard, if not impossible in most cases.
