Take a good look at those servers sitting in that closed room at the end of your office hallway. You might be surprised by the numbers if you did. What is the real cost of ownership of servers? The first thing you have to do is look beyond the initial costs of an in-house solution vs. Look at ongoing costs instead. What are you really paying to operate, maintain and upgrade an on-premises solution over its lifetime usually a five-year period? What other costs are involved in a cloud solution?
Image hosting role

An image service provides access to raster data through a web service. By default, an image service is always published with image service capabilities, and you can optionally choose WMS and WCS capabilities. Image servers can be federated with ArcGIS Enterprise deployments to enable imagery publishing and to perform distributed raster analysis based on the assigned server role.
The amount of data hosted by Internet servers and data centers is increasing at a remarkable pace requiring more capable and more efficient servers. However, physical efficiency does not necessarily correlate with computational efficiency. In fact, independent studies reveal that Internet servers are mostly over provisioned and still additional servers are deployed each year. Understanding the characteristics of the workload of servers is an essential step to efficiently manage them. For example, from the workload statistics, it is possible to predict idle or underutilized states and to consolidate workload, so that the idle or underutilized servers can be switched off. In this paper, we systematically analyze the characteristics of video servers — since they are responsible for producing the largest Internet traffic — and provide an insight into the relationship between the statistics pertaining to workload, the size of videos, and service time. We shall show that from the distribution of the video sizes on host servers, it is possible to estimate the distribution of the workload size produced by clients and the distribution of the time required to process individual requests.
