#AWS launched Lambda Managed Instances at re:Invent last year. Your Lambda functions, running on #EC2. Zero cold starts. Savings Plans apply.
I wrote about this exact problem a few weeks ago.
I ran 30+ Lambda functions serving 1.8M connected devices. Traffic started spiky. Serverless was perfect. Then telemetry hit constant throughput, 24/7. Millions of invocations on a workload that never scaled to zero. An idea that could have helped: move the hot path to #ECS #Fargate.
Lambda Managed Instances is the third option I didn't have. Same #Lambda DX.
EC2 pricing plus a 15% management fee. Multi-concurrency per environment. Savings Plans finally apply, up to 72% off. No containerization.
#Serverless-first doesn't mean Lambda-forever. The best architecture lets you graduate without rewriting.
Check your Lambda cost report. If any function runs flat traffic above $500/month, the escape hatch is live.
