In this 34th quarterly recap post, discover the most impactful AWS serverless launches, features, and resources from Q3 2026 that you might have missed.

Learn how to configure PostgreSQL logical replication between two Amazon RDS for PostgreSQL instances on separate AWS Outposts racks, keeping all replication traffic and backups within your on-premises environment by using Customer-owned IP addresses and Local Gateways, without any data traversing the AWS Region.

Amazon EC2 Capacity Manager offers real-time supportability checks and capacity fulfillment metrics for large EC2 fleets. This post shows how to measure how well your instance type and Availability Zone flexibility performs, find where capacity is strongest before a scale-up, and add it to Auto Scaling groups, Amazon EC2 Fleet, or Karpenter.

AWS Lambda event source mappings now support queue consumption mode for Apache Kafka. Using Kafka Share Groups, you can scale consumer parallelism independently of partition count, with per-record acknowledgment, visibility timeouts, and automatic retries on self-managed Kafka 4.2 or later clusters.

Learn how to build end-to-end observability for AWS Outposts across four dimensions: network, storage, compute, and containers. This post uses AWS Systems Manager, Amazon CloudWatch, and Amazon EventBridge for unified visibility and automated incident response across hybrid infrastructure spanning your data center and an AWS Region.

Durable functions span many Lambda invocations, so per-invocation logs answer the wrong question. The Durable Execution Telemetry Exporter is an SDK plugin that emits one complete record per execution to any of 13 destinations with a one-line change, and a companion MCP server lets an AI agent query that data in plain language.

Learn how an AWS Lambda function and an Amazon Bedrock AgentCore agent investigate a folder of related documents together through a shared Amazon S3 Files file system, using ordinary file operations instead of object download and upload code.

Amazon EC2 Replace Root Volume with the direct Amazon EBS volume option lets you prepare and validate a replacement root volume in advance, then swap it onto a running production instance with a single reboot. Learn how to upgrade the OS and apply patches while the instance keeps its production identity, including instances in Auto Scaling groups.

Learn how to build a five-step Agent Engine Optimization (AEO) scoring pipeline on AWS Lambda durable functions. Each checkpointed step suspends without incurring costs between stages and retries without re-spending on prior work, so you can score any page against five AEO signals and deploy the solution with an AWS SAM template.

AWS re:Invent 2026 offers an extensive selection of serverless and application integration content, including new AWS Lambda execution models, AI agents as a new kind of serverless consumer, and maturing event-driven patterns. This guide helps you navigate the serverless sessions and find the content most relevant to you.
