The software makes it really easy - no need fiddling around with other people's tools or managing servers! Just drag files from anywhere onto an endpoint machine (using any standard unix tool) which can be scaled up as necessary in minutes rather than hours/days if you had been doing this otherwise before using atscale.
We've just begun our evaluation process but so far we're very happy about what they provide us already compared against more expensive alternatives like Hadoop etc plus there are lots less things that break :) This gives me peace knowing where my code lives now instead being dependent upon third party services such as HDFS / GCS! The ease in which you can create new environments/virtual machine instances with atscale makes it easy as well! I do not have any dislikes about this product so far - everything has been great since we started using them (almost 2 years now). We use these products mainly because they are scalable but also very reliable when used correctly by your team members who know what's going around there :).
