Summary of AZ-900 Episode 1 | Cloud Computing and Vocabulary | Microsoft Azure Fundamentals Full Course

Cloud computing is a delivery model for services like storage, offering a wide range of services and tools for data storage and migration.

Cloud computing involves creating applications and connecting components securely, with the ability to review performance and telemetry data.

scalability involves increasing or decreasing the size of resources vertically (scaling up) or horizontally (scaling out).

Elasticity allows the system to dynamically scale resources based on workload changes, with automatic scaling being a key feature.

Agility in the cloud refers to the ability to provision and deallocate resources quickly, compared to on-premises environments.

Fault tolerance ensures system uptime during component or service failures, with built-in fault tolerance in cloud services.

Disaster recovery involves setting up replication between regions to ensure system functionality after a major disruption.

High availability measures system uptime versus downtime, with companies aiming for high availability to minimize downtime.

Cloud services offer high availability by default, but critical systems may require specific tools and design for achieving high availability.
