Can provide low-latency access between application components in an on-premises data center and and an existing VPC
Outposts
Difference between direct connect and outposts?
Direct Connect is used for creating a low-latency private connection to an on-premises data center but it cannot be used to extend the VPC like Outposts
A VPC allows you to deploy across multiple…
Availability Zones
What is difference between an AZ, edge location, and region?
Availability Zone - one or more physical data centers.
Region - A completely isolated geographic location with 3-6 AZs.
Edge Location - Used by Amazon CloudFront for caching content.

What is the difference between:
Virtual Private Gateway
Customer Gateway
Transit Gateway
Virtual Private Gateway : The VPN concentrator attached to the Amazon VPC side of the VPN connection.
Customer gateway : Hardware or software based VPN concentrator on the customer side of the VPN connection.
Transit Gateway : Acts as a single router and gateway between all the connected VPC, on-premise data center, or remote office networks.
Customer Gateway
A customer gateway is a physical device or software application on your side of the VPN connection.
What is VPC peering?
sharing of data over private connections between two accounts within a region.
A VPC peering connection helps you to facilitate the transfer of data. For example, if you have more than one AWS account, you can peer the VPCs across those accounts to create a file sharing network. You can also use a VPC peering connection to allow other VPCs to access resources you have in one of your VPCs.
