In the previous issue, AI Agents on Serverlessšāļø #101 we looked into how the AI Agents are deployed on Serverless.
The conversation around AI automation has officially shifted. Weāve spent the last two years hyper-focused on the brainsāthe models, the prompts, and the agentic logic.
Something from the recent announcement that catches my attention is -
SAM CLI + BuildKit = True Velocity: We are writing features faster than ever, which means slow, sequential container builds are the ultimate bottleneck. By bringing native BuildKit support into the SAM CLI, AWS enables multi-stage builds to execute independent steps in parallel. Layer caching now tracks file-level changes instead of rebuilding entire chunks from scratch. Your deployment loop drops from minutes to seconds, matching the speed of thought.
Predictable Cost Grid via EventBridge Scheduler: Running high-memory, warm instances full-blast at 3 AM when your engineering team is asleep is a massive waste of cloud budget. Amazon EventBridge Scheduler just added 619 new SDK API actionsāincluding direct support for Lambda Managed Instances. Without writing a single line of custom integration code, you can set a time-based cron schedule to scale your LMI capacity up at 8:30 AM and drop it down to zero at night. That is true, precise control over your capacity provisioning, natively managed by the cloud.
Build optimization, scalability at ease! Thatās the era of Serverless we want to be in with the AI Agents taking over.
