High availability
High availability refers to a system's ability to remain operational and accessible for a long period, minimizing downtime. It often involves redundant components, such as servers and networks, so that if one part fails, another can take over seamlessly. This is crucial for businesses, especially those reliant on online services, to ensure users can access their services without interruptions. High availability aims to provide consistent performance and reliability, making sure services are always "up" and functioning, even during failures or maintenance.

High availability refers to a system's ability to remain operational and accessible with minimal downtime, ensuring it is always ready for use. This is achieved through strategies like redundant hardware, backup power supplies, and failover processes that kick in if a primary component fails. For example, websites that experience very little downtime, even during high traffic or technical issues, showcase high availability. It’s crucial for businesses that rely on constant access to services or data, as it helps maintain productivity and customer trust.

High Availability (HA) refers to a system's ability to remain operational and accessible with minimal downtime. It ensures that services or applications are consistently available, even in case of failures or issues. This is achieved through redundancy, where critical components are duplicated so that if one fails, another can take over immediately. Businesses often use HA to protect against data loss and ensure smooth operations, which is crucial for maintaining customer trust and satisfaction. Essentially, HA aims to provide uninterrupted service, minimizing the impact of outages on users.
