Data is the currency of today's web, mobile, social, enterprise and cloud applications. Ensuring data is
always available is a top priority for any organization. Minutes of downtime can result in significant loss
of revenue and reputation.
There is no "one size fits all" approach to delivering High Availability (HA). Unique application
attributes, business requirements, operational capabilities and legacy infrastructure can all influence
HA technology selection. And technology is only one element in delivering HA: people and processes
are just as critical as the technology itself.
MySQL is deployed into many applications demanding availability and scalability. Availability refers to
the ability to cope with, and if necessary recover from, failures on the host, including failures of MySQL,
the operating system, or the hardware and maintenance activity that may otherwise cause downtime.
Scalability refers to the ability to spread both the database and the load of your application queries
across multiple MySQL servers.
Because each application has different operational and availability requirements, MySQL offers a
range of certified and supported solutions, delivering the appropriate levels of High Availability (HA)
and scalability to meet service level requirements. Such solutions extend from replication, through
virtualization and geographically redundant, multi-data center solutions delivering 99.999% uptime.
Selecting the right high availability solution for an application largely depends on:
• The level of availability required.
• The type of application being deployed.
• Accepted best practices within your own environment.
