The team at css has helped us with our implementation which involved moving multiple applications from an existing hosting provider into AWS Cloud (EC2). We were looking forward towards getting all things up & running faster than what we had experienced before when working out side their infrastructure/team - this was achieved! This includes setting everything live as well ensuring that there's no downtime during migrations or any other issues they faced while helping me migrate my apps onto EC 2 instances hosted by them across different regions within US West 1 zone only!! I found it very easy going experience till now having worked alongside @krishna_suresh who handles customer support end always ready help you through your queries related migrating application servers etc., He makes sure he understands every detail about his customers problems rather then just giving solutions but also gives suggestions regarding how can one improve upon same.
