Question

Striving for 100% Uptime: Some businesses and services simply cannot afford to go down, even for a very brief period of time. These businesses strive for reaching 99.99%, 99.999% or even 100% uptime during the year. Research and give examples of cases where this level of uptime is required and mention which advanced cloud architectures are usually used to aid in reaching this goal.

Answer 1

Some of the businesses which strive for 100% uptime of servers, are as follows:

• Life support systems: These systems need to be up with 100% accuracy as the life of the patient is dependent on the uptime of the system.
• Surveillance trackers: These trackers are used to keep a track of any kind of anti-social activities at the border and high security zones. These trackers are also integrated in satellites so as to keep the terrorist activities in check. If these trackers go down, then the overall safety of the country may get compromised.
• Air traffic control system: Air traffic control system keep a track of the airlines in the atmosphere. If these systems go down, then there is high probability of an air accident taking place. Hence it is highly critical that the servers of these systems are up, most of the time.

Zero downtime cloud architecture is the most preferred cloud architecture in these kind of systems. The zero downtime architecture helps in maintaining the functionality of the systems with zero or minimal downtime. The reliability as well as resiliency of such systems is also quite high.
