Every company wants to leverage the cloud for the agility it provides. Running in the cloud can also provide significant cost savings. But, not always. The reason is that when running large workloads in the cloud, they are not predictable. You have to either over-provision query capacity to handle spikes in demand, or provision for the average and risk disappointing customers during those black Friday events.
The MarkLogic® Query Service provides immediate query capacity to handle spikes in demand. And, when demand slows, that extra capacity is removed. Because it is a service, you just have to define what capacity to start with and what spikes will be expected. The service keeps a close watch on your system and adds or removes capacity as needed. It is automatic, all provisioned, and all handled by the service running in AWS.
