Insightful! But, would've been a complete guideline if there is any follow-up technical hands-on course. That aside, satisfied. Got an overview of SaaS & multi-tenancy.

Really nice and detailed explanation on some of the key topics related to SAAS architecture. Good assignment selection as well..

Folks who have worked on client server architecture - its similar concepts. Probably criteria for audience should be well defined to subscribe for the course. While the course is good for beginners.

The course provides a good comprehensive overview of various things to be taken care of while designing a SaaS application. Pretty informative if you are into SaaS development or thinking to start with the same!! It might not be for absolute novice(as clearly mentioned by the instructor in preview section itself) but if you have some background in the development space, you would be able to follow!!

It is good starting point to understand how to design SaaS application but could have better if it would have included some more examples with HLD

Really appreciated this course. I'm a lawyer working in the sector (and has done some basic web development and had no problems understanding the concepts (it gave me a better understanding of the concepts). It would have been great to have the presentation material made available as a reasource to take optimal notes/get a better understanding, especially for the scaling and multi-tenancy sections.

Yes - the course was a good match for my needs. I am new to Saas and i did learn a lot of basics of Saas applications through this course.

Really detailed information about SaaS from start to finish. Highly recommended if you are going to be working with SaaS environments, clients or proposals.

es war ein sehr interessanter Kurs. Ganz gut erklärt. Leider gibt es keinen Foliensatz dazu, um die Themen noch mal nachzulesen - dafür einen halben Stern Abzug

The course is not playing properly for me. I have to go through by forwarding the course manually (without and sound or video) and only able to read transcript which is not very clear.

It is my mistake that I got to this course after the 30 days of trial period. I would have asked for a refund otherwise. It is quite clear from the first section itself that the author does not fully understand fundamentals or at least not able to convey information properly. Author must do thorough research of why companies are taking SaaS approach and how it really differs from traditional one.

It'a really good course for a person who is not familiar with the SaaS area. Everything is explained clearly and Kumaran gives examples to the theory, which helps a lot. Thank you for this course.

Very good course: well structured and presented. Some of the topics I would consider general software architecture topics - i.e. not SAAS-specific - but it is hard to draw the line.
October 20, 2020
A good overview of architecting SaaS applications. It covers all the basics. Ideally, I'd like some direction towards some deeper reading of the concepts covered but it's a good overall view. Thanks, Kumaran.
