Longest Prefix Match: Understanding Advanced Concepts in VPC Peering

2023-08-14T02:40:31+00:00

VPC Peering Basics In AWS, a Virtual Private Cloud (VPC) peering connection is a networking connection between two VPCs which allows you to route specific traffic between them using either private IPv4 addresses or IPv6 addresses. A VPC peering connection can be created between your own VPCs, or alternatively, a VPC in another AWS account. You can also create an inter-region VPC peering connection where the VPCs are located in different AWS Regions. Amazon EC2 Instances in either VPC can communicate with each other freely as if they are within the same network. One example of VPC Peering is the [...]

How to invalidate API Gateway Cache

2021-05-03T13:34:08+00:00

To invalidate an existing cache entry of a request and retrieve the latest data from the integration endpoint, one must send the request together with the Cache-Control: max-age=0 header. If the recipient is authorized to communicate directly to the integration endpoint, then the integration endpoint will respond with the latest data for the request. This also replaces the existing cache entry with the new response. The IAM Policy that grants a client to invalidate the cache follows: {   "Version": "2012-10-17",   "Statement": [     {       "Effect": "Allow",       "Action": [         "execute-api:InvalidateCache"       ],       "Resource": [ "arn:aws:execute-api:region:account-id:api-id/stage-name/GET/resource-path-specifier"       ]     }   ] }    An alternative option [...]

VPC Peering

2025-12-26T16:41:28+00:00

VPC Peering Cheat Sheet A networking connection between two VPCs that enables you to route traffic between them privately using private IPv4 addresses or IPv6 addresses. Instances in either VPC can communicate with each other as if they are within the same network. You can create a VPC peering connection between your own VPCs, with a VPC in another AWS account, or with a VPC in a different AWS Region (also called Inter-Region VPC Peering). A VPC peering connection is neither a gateway nor an AWS Site-to-Site VPN connection and does not rely on a separate piece of physical hardware. [...]
