The challenges we faced with AWS X-Ray were that some of the AWS services we were using did not support it, which we discovered at a later stage. This was potentially a design consideration we should have known about, requiring us to redeploy some services in another SKU version to get it functioning. This is the only challenge, as AWS X-Ray is relatively new. It is important to consider that not all AWS services support it out of the box. My recommendation for AWS X-Ray would be broader support. We have been working in a relatively small area of AWS, using approximately six or seven services, so I have not explored all other available services. In general, the more services it supports, the better it would be. AWS X-Ray should be able to support more services for improved functionality.
