Our review
Pros	Scales automatically from zero to peak demand. Supports managed and custom runtimes, ZIP packages, and container images. Connects with AWS services and supports durable multi-step functions.	Deploy container images or source code, and build images from source Run applications, event-driven functions, batch jobs and serverless fleets Scale applications automatically, including to zero, and bind IBM Cloud services
Cons	Execution duration and other AWS services can add charges. Custom domains require API Gateway rather than Lambda function URLs. Maximum execution time is 900 seconds.	Pay-as-you-go charges vary with CPU, memory and HTTP request consumption Workload management relies on IBM Cloud interfaces or Kubernetes-compatible tooling The platform is focused on serverless workloads rather than conventional hosting
Our verdict	AWS Lambda runs functions and applications without requiring teams to provision servers. It is aimed at teams building event-driven workloads, HTTP endpoints, and real-time data processing, especially those working with AWS services.
