In modern enterprise cloud architectures, applications rarely live in a single AWS Virtual Private Cloud (VPC) or even a single AWS account. Production environments are partitioned across dozens or hundreds of accounts for blast-radius isolation, compliance boundaries, and autonomous team ownership. However, securely interconnecting these distributed microservices has long been one of the most frustrating […]

Declarative Stream Processing: EventBridge Pipes vs. Custom Lambda Glue
EventBridge Pipes is usually sold as cheaper and lighter on concurrency than a Lambda stream consumer. Checked against the AWS documentation, both claims mostly disappear once the consumer filters on its event source mapping. This article compares the two for a DynamoDB Streams to EventBridge integration, with tested code, a reproducible cost model and a decision framework.

The API Gateway 29-second timeout is now a default, not a wall: REST APIs can stream for 15 minutes, and Lambda durable functions and Bedrock AgentCore handle work that runs for hours. This article sets out the current limits, three production patterns for long-running GenAI requests with tested code, and the concurrency and cost consequences of each.

For nearly a decade, executing JVM and .NET serverless architectures inherently required accepting terrifyingly high multi-second cold-start initialization times. By deploying Firecracker MicroVM snapshotting arrays, AWS Lambda SnapStart fundamentally eliminates these bottlenecks instantly restoring memory. Here is a thorough practitioner guide navigating state constraints, securing CRaC hook workflows, and defeating broken deterministic UUIDs.
