What is High Availability?
The ability of a service to be continuously available by minimizing downtime
How is High Availability achieved?
Achieved through load balancing, clustering, redundancy, and multi-cloud strategies
What is Uptime?
The time a system remains online, typically expressed as a percentage
What are the Five nines?
Refers to 99.999% uptime, allowing only about 5 minutes of downtime per year

What is Load Balancing?
The process of distributing workloads across multiple computing resources
What is Clustering?
Use of multiple computers, storage devices, and network connections as a single system to provide high availability, reliability, and scalability
What is Redundancy?
Involves duplicating critical components to increase system reliability
What does the Multi-Cloud Approach do?
Distributes data, applications, and services across multiple cloud providers
What does the Strategic Planning do?
