We discuss common use cases and challenges for copying data between S3 buckets and S3-compatible object storage services. We share our experience building an open source Node.js CLI tool called S3-Migrate to efficiently migrate data with separate source and destination credentials. We cover performance considerations like streaming, chunk sizes, concurrency and parallelism.AWS Bites is brought to you in association with fourTheorem.

In this episode, we provide an overview of AWS Step Functions and dive deep into the powerful new JSONata and variables features. We explain how JSONata allows complex JSON transformations without custom Lambda functions, enabling more serverless workflows. The variables feature also helps avoid the previous 256KB state size limit. We share examples from real projects showing how these features simplify workflows, reduce costs and enable new use cases.AWS Bites is brought to you in association with fourTheorem.

In this episode, David Lynam provides an overview of AWS Transit Gateway, which aims to simplify complex network connectivity between VPCs, VPNs, and on-premises networks. We discuss the limitations of using VPC peering and the benefits Transit Gateway provides through its hub-and-spoke model. The main components of Transit Gateway are explained, including attachments, route tables, associations, and route propagation. We go through some example use cases like sharing Transit Gateways across accounts, network isolation for compliance, routing traffic through security services, and bandwidth/scaling capabilities.
