AWS CDK is an open-source framework for defining cloud infrastructure in code, synthesized into CloudFormation templates for deployment.
No evidence-backed relationships are recorded.
AWS opened a preview of Well-Architected Agent, a service that reads live accounts across 65+ services and ranks fixes against goals each team declares. The review becomes a job run against the real environment, and every fix comes back as code or commands for the team to apply.

AWS says Trane's engineers cut a 20-minute dashboard workflow to a 20-second question in three to four weeks. The multiple rests on timings Trane ran with its own technicians, and the durable part is where the tool calls execute.
Reality
Tetragon ran inside a CodeBuild GitHub Actions runner and killed /usr/bin/curl when a dependency's postinstall script tried to reach a non-loopback address. The control needs a pinned host kernel and privileged mode.

A dev.to walkthrough gives a Nova Sonic voice agent and an Amplify AI Kit chat agent one long-term memory in Amazon Bedrock AgentCore Memory, where every record is filed under an actorId and a sessionId. Both channels already had short-term context.
Reality
On a self-hosted spot runner, an instance AWS reclaimed and a genuinely broken test both produce the same red X, so this pipeline reads the raw job log for four host-only strings and re-runs only the jobs the host killed.

DynamoDB vector search has been generally available since August 5, 2026. A walkthrough of a serverless search engine shows what a single Lambda actually buys with it, and what choosing 512 dimensions commits a catalogue to.

IAM Access Analyzer already names the unused permissions and writes the tightened policy. A new AWS pattern sorts each finding by how the role was created and files the fix as a pull request or an issue.
Reality
The AgentCore lifecycle stack defaults episodic memory to 90 days, while the same post recommends 30 to 60 days for summaries and 6 to 12 months for semantic facts. The default is a placeholder to fork before production.
Reality
AWS now ships a first-party catalog for agents, tools, skills and MCP servers, moving the hard part off building them and onto whoever keeps the records current and clears the approval queue, a staffing question as much as a platform one.
Reality
Express Mode turns a container image and two role ARNs into an HTTPS service on Fargate. The engineering question it leaves behind is which of its inherited defaults match your workload and which will quietly fight it.
Reality
A correct-looking batchItemFailures handler is inert unless the event source mapping agrees. One dev.to write-up grades the code-versus-mapping mismatch higher than the missing setting, and says why.
Reality
AWS puts a Claude-powered Connect agent on a real phone number and reaches the restaurant backend over MCP. The unforgiving part is the pause the caller hears while that happens.
Reality
The default rule set ships on in warning mode from aws-cdk-lib v2.261.0. Strict mode is one context key away, and the exit-code change on declined prompts is the quieter risk.
Reality
A June 2026 AWS audit found the biggest fixed line was a framework default, not a feature. The test that caught it was pricing each charge at 100x usage instead of today's.
