AWS Fundamentals
Last updated:
AWS Public vs Private services
Refers to networking only Three internet zones: Public Internet Zone (Open internet) AWS Public Zone (Things like S3 for AWS public services. Requires access.) AWS Private zone (VPCs: isolated unless configured otherwise. Stuff can be placed inside VPCs like EC2. Access can be enabled by using things like VPN/Direct Connect for on prem, for public access things like internet gateway)
AWS Global Infrastructure
Regions
An area AWS says has full deployment of AWS services (Ohio,Mumbai, etc.)
Edge locations
Edge computing, CDNs, type of things. Allows for fast, efficient data transfer. Some services are global (IAM/DNS) Some are regional (EC2, etc)
Region benefits
Geographical separation (isolated fault domain) Geopolitcal separation (Different governance) Location control (Performance)
Regions and AZs
Each region has between 2 and 6 AZs. Isolated infra inside a region. AZ is not one DC. It can have more than one DC.
Service Resilience
Globally Resilient (If a region fails, no issues. Examples: IAM, Route 53) Regionally Resilient (Regionally, data is same. Region fails, service will fail) AZ Resilient (very prone to failure)
AWS CLI
Create profile
aws configure --profile iamadmin-general
