Abstract
The Internet of Medical Things (IoMT) is a blend of medical devices and applications, which promotes clinical knowledge of network technology to analyze medical data. The IoMT supports the patient to share their medical data with the doctor in a secure manner. There is an exponential growth in the implementation of IoMT in healthcare, but there are still some crucial problems in medical data security. Cloud computing technology offers a new application without network issues in an optimized manner and with the quickest access service. In cloud computing, medical data management takes place in an Infrastructure as a Service in the data center. These medical data are stored in a virtual machine (VM) that can be transferred easily without data loss to other data centers. VM migration is a part of cloud computing that provides system maintenance, fault tolerance, load balancing, and reliability to the users. There are many migration approaches are available in the present scenario. We are going to discuss the pre-copy live migration technique where all active memory pages are transferred and then execution takes place. Downtime and overall migration time are significant problems in ...
