An interview on the performance challenges of FaaS cloud architectures

Bas van Essen:
Ok, onwards to the performance challenges you see regarding FaaS architectures. Can you describe them shortly?Johannes Grohmann:
We identify six major performance challenges:
(1) Overhead:
The FaaS platform introduces some overheads (e.g., provisioning overhead when starting a new function instance) which might prevent adoption for some use cases. (6) Evaluating and Comparing FaaS Platforms:
As the trend of serverless platforms is somewhat new, there is a lack of standardization and benchmarks of FaaS platforms, which prevents making informed decisions when it comes to evaluating FaaS offerings.
