AWS Basic Concept

• outline

To use and create AWS services, there are basic things you need to create and understand the relationships between them.

• Account

AWS account is a kind of container for AWS resources. You can create and manage AWS resources within your AWS account, and the AWS account provides management features for access and billing.

• Region

AWS has the concept of a Region, which is a physical location around the world where we cluster data centers. (ex. ap-northeast-2, us-east-1)

• Availability zone

An Availability Zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region. (ex. AZ1, AZa, AZ2, AZb)

• VPC

Amazon Virtual Private Cloud(Amazon VPC) is logically isolated virtual network that you've defined and can be assigned to one or more Availability Zones.

• Subnet

The IP address range of the VPC, residing in a single Availability Zone. (ex. pri_sub_a, pri_sub_b, pub_sub_a, pub_sub_b)

• Basic Concept

• note

Except for a few services such as IAM, S3, WAF, and VPC Peering, most AWS services can be created and used by assigning them to a VPC.
