How many 9’s of availability did your IT infrastructure experience last year? Private cloud? Public cloud (single)? hybrid cloud? Multi cloud? It does not matter at the end of the day what your preference is as long as your business services are available 24x7x365.
Just to put it into perspective, below are some simple representations… And do not be too hard on yourself, world known titans like AWS and FB did not even meet 99.99% themselves.
99.9999% = less than 31 seconds of downtime in the entire year
99.999% = less than 5 minutes of downtime in the entire year
99.99% = less than 1 hour of downtime in the entire year
99.9% = less than 9 hours of downtime in the entire year
99% = less than 4 days of downtime in the entire year
In which category does your infrastructure’s availability fit best?
If you are part of the 6x 9’s of availability, HUGE congratulations to you and your team!
