Auto Scaling

Use: To adjust resources based on demand.
Triggers: Pre-Configured Policies.

Image Types

Private Image: Only available to user who created it.
Public Image: Standard image provided by cloud platform.
Marketplace Images: Provided by third-party service providers.

Virtual Private Cloud (VPC)

Purpose: To provide a secure and isolated environment for cloud resources.
Features: Subnet creation, route tables, EIP assignment, bandwidth configuration, and security group configuration.

Basic Unit: vCPUs, Memory, OS.
General Computing Specifications: s6.small.1
System Disk Options: General Purpose, Ultra-High I/O, Extreme SSD
Default Username (Linux ECS): root

Other Services

Security Group: Collection of access control rules for the VPC.
Elastic Network Interface (ENI): Virtual Network Interface.
Elastic IP (EIP): Enables cloud resources to communicate with the internet.
Virtual Private Network (VPN): Encrypted communications tunnel between on-premises and cloud.
Elastic Load Balance (ELB): Distributes traffic to multiple backend servers.
Network ACL: Controls traffic in and out of a subnet.
Bare Metal Server (BMS): Provides dedicated servers on the cloud.
Top-of-Rack: How server cabinets are wired.
Image: Template containing OS, data, and application software.

Required: Tenant Name, Username, IAM user password.

Billing Modes

ECS: Pay-per-use, Yearly/Monthly, Spot Price.
Subnet Creation: NOT a billing mode.

Additional Notes
