I would highly recommend CloudThat. I have witnessed the leadership first-hand and I am confident that CloudThat will always deliver the highest QoS, often delivering more than asked and always ready to help. One incident that he was immensely helpful, was one moment when our Solr Collection index in our production got corrupted and this we got to know at about 8:45 PM on a Friday. So I called the team and they were ready to help instantly. We then worked until ~4:30 AM the next morning, to get this resolved.
