Function delivery Network

Question 1

Heterogeneity in Serverless Deployments

Answer 1

Hw-config-based
Location-based
Platform-based hetero faasd

Question 2

Why heterogeneous clusters ?

Answer 2

Using specialized architectures and hardware
Overcoming limitations of FaaS platform and cloudbursting
Data locality, data-privacy, not all cloud providers have data centers in all regions

Question 3

What is FDN?

Answer 3

FDN extends the Function-as-a-Service paradigm to heterogeneous computing. It is a network of distributed heterogeneous serverless compute clusters spread across the edge-cloud continuum.
Furthermore, it provides a programming interface that enables the execution of functions across the continuum.

extension to the concept of FaaS as a programming interface for heterogeneous clusters and to support heterogeneous functions with varying computational and data requirements.

Question 4

What is the primary motivation behind the FDN?

Answer 4

1. Support for only homogeneous nodes in commercial FaaS platforms such as Google Cloud
   Functions.
2. Support for execution of functions with specialized hardware requirements.
3. Overcoming the limitations of a particular FaaS platform such as the maximum concurrent function instances supported by AWS-Lambda.
4. Addressing data-locality and data-privacy concerns.

Question 5

What are the different types of platforms supported by the FDN for function execution?

Answer 5

The FDN currently supports function execution on edge devices, FPGAs, HPC nodes, and private and public cloud clusters.
