Elasticity is the ability to automatically scale computing resources up or down based on demand. This cloud computing characteristic allows systems to dynamically acquire resources when needed and release them when demand decreases, optimizing cost and performance.
An Availability Zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region.
A Region is a physical geographic location consisting of multiple, isolated, and physically separate Availability Zones within a specific area.
AWS Identity and Access Management (IAM) is a web service that enables secure control over access to AWS resources.
Amazon Simple Storage Service (S3) is an object storage service offering industry-leading scalability, data availability, security, and performance.
Amazon Elastic Compute Cloud (EC2) is a web service providing resizable compute capacity in the cloud.
Amazon Virtual Private Cloud (VPC) is a logically isolated section of the AWS cloud where resources can be launched in a defined virtual network.
Amazon CloudWatch is a monitoring and observability service that collects and tracks metrics, logs, and events from AWS resources and applications.
AWS Lambda is a serverless compute service that runs code in response to events without provisioning or managing servers.
Amazon Relational Database Service (RDS) is a managed database service that simplifies setup, operation, and scaling of relational databases in the cloud.
