We have used scalex elements in our previous projects as well. I like everything about it from UI/UX design of dashboard etc., upto support team also very responsive at any level. Nothing much i dislike currently though we had some minor issues with cloud service provider but they resolved within few days without asking us too many questions or charging extra amount (which was good!). Its easy solution if you are looking just one tool which will take care your compute power requirement along with performance monitoring aspect. You can use this product if you want ease of implementation and need something more robust than AWS services. Scalability is needed when there are massive data sets running throughtout day time hours so that these jobs don't slow down due process creation speed.
