FLY is a parallel work-flow scripting imperative language inspired by functional languages peculiarities. FLY uses two type of run-time environment: the local machine and/or cloud infrastructure. FLY perceives a cloud computing infrastructure as a parallel computing architecture on which it is possible to execute some parts of its execution flow in parallel.
FLY main goals are:
- expressiveness, in deploying scientific large-scale computing work-flows;
- programming usability, writing .fly program should be straightforward for domain experts, while the interaction with the cloud environment should be completely transparent; the users do not need to know the cloud providers APIs;
- scalability either on symmetric multiprocessing (SMP) architectures or cloud computing infrastructures supporting FaaS.
FLY is compiled in native code (Java code) and it is able to automatically exploits the computing resources available that better fit its computation requirements. The innovative aspect of FLY is constituted by the concept of FLY function. A FLY function can be seen as an independent block of code, that can be executed concurrently.
