Explanation

High Availability (HA) is a system design goal that ensures the system or network can continue to operate and provide the expected level of service and performance during planned or unplanned outages or disruptions. To achieve HA, the system or network needs to have various components and features that enhance its reliability, availability, and resilience. Some of these components and features are clustering, load balancing, and fault-tolerant options. Clustering is the process of grouping two or more servers or devices together to act as a single system and provide redundancy and scalability. Load balancing is the process of distributing the workload or traffic among multiple servers or devices to optimize the performance and efficiency of the system or network. Fault-tolerant options are the mechanisms or techniques that enable the system or network to detect, isolate, and recover from faults or failures without affecting the service or performance. Clustering, load balancing, and fault-tolerant options can help to achieve HA by ensuring that the system or network can continue to operate and provide the expected level of service and performance during planned system outages, such as maintenance, upgrade, or backup. Redundant hardware, disk spanning, and patching, load balancing, power reserves, and disk spanning, or backups, clustering, and power reserves are not the best components or features to include in order to achieve HA during planned system outages, as they are more related to data security, data protection, or data recovery aspects of HA.
