Serverless computing part 2

Question 1

What are the advantages of serverless architecture?

Answer 1

• -Cheaper than the traditional cloud. Apps are metered in up to tens of millisecond of granularity.

What are the disadvantages of serverless architecture?

Answer 2

• -Vendor lock-in. Although big vendors have similar FaaS but the details are significantly different.
