Modern architecture alternatives and their pros and cons are debated in this panel discussion from autocon/22. While the right choice is organization-specific driven by application needs and organizational capabilities, the case is made that serverless is underutilized at many companies given its operational advantages.

Panel members:

Rachit Lohani, CTO & SVP (Engineering and Product), Paylocity

Siddharth Ram, Ex-CTO, Inflection & VP/Engineering Fellow, Intuit

Shridhar Pandey, Senior Product Manager, Lambda, AWS

Kenneth Nguyen, Co-Founder, Tasq

Salil Deshpande, General Partner, Uncorrelated Ventures (moderator)

Key moments:

00:00 : Context for the choice between serverless and Kubernetes

02:23 : Why not run stateless and just use serverless and autonomous?

05:52 : Why Inflection moved from Kubernetes to serverless

08:13 : What about vendor lockin with serverless?

08:57 : Paylocity Heavily Uses Serverless

10:25 : The 5 Steps to Get to Autonomous

11:02 : Getting to Autonomous in Stateless vs Stateful

12:40 : Why Paylocity Converted Almost Completely to Serverless

14:03 :Kubernetes Helps with High Throughput, Cold Starts, Latency Sensitivity

14:35 : Rachit's POV on Managing Kubernetes

15:47 : Refactoring Kubernetes to Serverless can be costly

16:44 : Paylocity's default approach is serverless; exceptions need a rationale

17:33 : Seek fewer variations & avoid abstraction complexity

19:14 : Lambda team aims to support different schools of thought

19:30 : Long running apps that wait for calls are not best fit for Lambda

21:29 : Why Intuit uses Kubernetes and Lambda

22:54 : Siddharth does see use cases for Kubernetes

23:11 : Tasq used serverless to iterate quickly

24:24 : Tasq now looking at distributed compute for processing (ECS, EKS, Fargate)

26:15 : Tasq's experience with serverless

28:30 : Solving for customer experience and minimizing ops work

30:55 : The Panel Compares Kubernetes, Serverless Containers and Serverless Functions

32:20 : Trading off more cloud spend for lower ops burden

33:25 : Kubernetes can make sense as scale grows

34:14 : Open multiple paths for dev choice

35:11 : Portability with serverless is getting easier

35:55 : Summary: Use high productivity approaches (e.g, serverless) as default, systems language (k8s) when needed
