fn can be triggered
-
Scheduled Invocation
using CloudWatch Events, allowing you to run your fn at specified intervals
Configuration
config your Lambda fn settings (eg. runtime (programming language), memory allocation, timeout duration any env variables)
-
-
Trigger Events

-
Type: Serveless compute. Use Case: automation tasks, event-driven fn2, microservices. Deployment: Deploy code as fn2. Execution Duration: short-lived
EC2 (Elastic Computer Cloud) - Virtual Machines
Type: Virtual servers in cloud. Use Case: databases, long-running processes. Deployment: deploy app on virtual machines (VMs). Execution Duration: long-running (no time limit)
