Longest Prefix Match: Understanding Advanced Concepts in VPC Peering
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.

You can also create an inter-region VPC peering connection where the VPCs are located in different AWS Regions. Amazon [...]
How to invalidate API Gateway Cache
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 [...]

Calculating the Required Read and Write Capacity Unit for your DynamoDB Table
Read Capacity Unit On-Demand Mode When you choose on-demand mode, DynamoDB instantly accommodates your workloads as they ramp up or down to any previously reached traffic level. If a workload’s traffic level hits a new peak, DynamoDB adapts rapidly to accommodate the workload. The request rate is only limited by the DynamoDB throughput default table limits, but it can be raised upon request. For on-demand mode tables, you don't need to specify how much [...]
AWS Lambda Integration with Amazon DynamoDB Streams
Amazon DynamoDB is integrated with AWS Lambda so that you can create triggers, which are pieces of code that automatically respond to events in DynamoDB Streams. With triggers, you can build applications that react to data modifications in DynamoDB tables. After you enable DynamoDB Streams on a table, associate the DynamoDB table with a Lambda function. AWS Lambda polls the stream and invokes your Lambda function synchronously when it detects new stream records. Configure [...]
