What is High Availability and how is it measured? In the world of IT, Availability refers to the annual percentage rate that a system is functional and working. Today, High Availability (HA) is the need and requirement of all the cloud based systems and business require continuous service delivery without any interruptions and cannot afford downtime. HA is one of the significant Architectural concern when it comes to designing solutions and applications. HA refers to an agreed level of operational uptime (measured in hours, minutes and seconds up to ...
