Availability

Why do we value availablity
To ensure business continuity, maintaining customer trust, upholding an organization’s reputation
How to maximize availablity
Through REDUNDANCY
Redundancy
Duplication of critical components or functions of a system with the intention of enhancing its reliablity
Different types of Redundancy
Server, Data, Network, and Power
Server Redundancy
Involves using multiple servers in a load balanced or failover configuration so that if one is overloaded or fails, the other servers can take over the load to continue supporting your end users
Data Redundancy
Involves storing data in multiple places
Network Redundancy
Ensures that if one network path fails, the data can travel through another route
Power Redundancy
Involves using backup power sources, like generators and UPS systems
