What is a difference between Lambda & Batch?

Following are the points which differentiate between 2 services.

• Time Limit (in which task should be processed)
• Limited Runtime (Programming Language) Options (as compared to AWS Batch)
• Limited Temporary disk space.
• Serverless

• No Time Limit
• Any runtime as long as it’s packaged as docker image.
• Rely on EBS/Instance Store for disk space.
• Relies on EC2. (Spot Instance or dedicated.. whatever..)
