Sorry for late response!
High availability technology is a very useful technology these days because it can effectively manage, distribute and ensure the availability of important data. For RAID technology can make a redundancy by utilising array of drives (depending on RAID type). If you need your data to be highly available and that data is too important and you cannot effort any risks of losing them, for example, patient history and medical records, billings — almost everything! Then, RAID (RAID-1 or higher) may be considered for use. In that case, it will certainly benefit both patients and hospital because there will be no interruptions delivering patient care. However, it might come with an additional cost for setting up a high availability system, but in the long run; it will ultimately provide a strong data protection in the future. Load balancing also ensure that the workload of data access is evenly distributed to all servers to reduce performance impact on a single node and thus, reducing delay in accessing data from users.
