To increase the protection level of copyright in cloud computing environment, aiming at the problems that the indicators in the copyright protection evaluation system are difficult to accurately define and cannot be quantified, a comprehensive evaluation model of copyright protection based on the combination of analytic hierarchy process and fuzzy comprehensive evaluation is proposed. Note that SLAs are often merely an indication of the consequences when the service fails and not the service's actual reliability. ©2020 C# Corner. Mainframes were large and high computing platforms. Providers offer virtual machines (VMs) that vary widely in memory capacity, CPU clock speed and other features. They can offer tremendous savings in terms of time and expense by shielding you from having to deal with lower level infrastructure setup and configuration. The answer is Mainframes. Performance evaluation in cloud computing is more challenging that the evaluation of systems where we are in direct control of all aspects (e.g., configuration, connectivity, and liveliness).
