Modern websites and applications are only as reliable as their underlying databases. Because of this, a dedicated database server is an essential element of any high-performance hosting infrastructure. High Availability (HA) Database goes a step further to safeguard your mission-critical databases and protect your business from costly downtime by ensuring that your databases are always accessible. An HA Database solution provides quick information replication between two redundant nodes — an active database server and a hot spare — utilizing enterprise-grade monitoring and failover tools. This redundancy also enables routine software upgrades, security patches, and hardware upgrades to be implemented with simple modifications.
