20. Cloud Redundancy

Cloud-Based Operations Many organizations use cloud-based facilities instead of maintaining their own server rooms because cloud services offer flexibility and built-in infrastructure support.

Cloud providers often use availability zones, so if one location has a problem, services can move to another location. This improves availability without the organization having to build and maintain its own full redundant data center.

Cloud services can also use different billing models, including usage-based pricing where cost depends on the resources or data used.

Another feature is resource pooling, where computing resources are shared and allocated as needed across multiple users or customers.

Main Idea Cloud services reduce the need for organizations to maintain their own data centers by providing flexible, shared, and highly available infrastructure.
