Erlang vs Orleans: What are the differences?
What is Erlang? A programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of Erlang's uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance. OTP is set of Erlang libraries and design principles providing middle-ware to develop these systems.
What is Orleans? An approach to building distributed applications in .NET. Orleans is a framework that provides a straightforward approach to building distributed high-scale computing applications, without the need to learn and apply complex concurrency or other scaling patterns. It was created by Microsoft Research and designed for use in the cloud.
Erlang can be classified as a tool in the "Languages" category, while Orleans is grouped under "Concurrency Frameworks".
Erlang and Orleans are both open source tools. Erlang with 7.75K GitHub stars and 2.1K forks on GitHub appears to be more popular than Orleans with 5.12K GitHub stars and 1.24K GitHub forks.
