The scalability of this software works very well with our cluster.It handles thousands of jobs without any issues which makes it reliable compared to other providers that I have used in the past.The price point is very fair as compared to their competitors. There are no downsides to scale experience elements at all from what i know so far. We use this software primarily for rendering. Our main focus is scientific simulations but we also do some video production work which requires large amounts of GPU compute power.
