Raj no doubt you are a distinguish architect. What a level of clarity in your explanations!!! Thank you for putting it together, really helpful to have an overview of different services and use cases!
Raj, This session is fantastic, I completed whole session during my morning walk with 1.5x speed. After listening couple of videos on CZcams I signup all of your courses and spread the word with my friends. Keep posting awesome videos, It is not easy job along with your daily Architecture job. I am trying to attempt my AWS security specialty exam during my preparation I found your KMS videos which fascinate me binge watching your CZcams series.
This made my day Surender! i am so glad my videos and courses helping you to achieve your cloud career goals. Thanks for spreading the word to your friends, much appreciated 🙏
Extremely helpful tutorial with clear insight into the basics / mechanics of the concepts. Can you please do a tutorial on - a) database options in AWS, when to use which b) storage / file system options

Raj, Can you add IDP & IDS section as part of System Design course. I noticed you are taking brief about IDP in one of the section. If not possible share CZcams video that will help many of cloud architects.
So much more nuanced that other videos that portrait monoliths as evil. They are not. Remember that Lamda Functiona have limits for how long they can run! They cannot be used for everything!
Thanks Santhosh 🙏. What I'd say is learn basic python, then boto3. Then jump into coding Serverless. Check out my Serverless course with Python i if interested (Discounted link in description)
Hi Raj I have a question. Can you give one example where we would use different DB for different Microservice, and one example where we would use only one DB instance for all the microservices? Thanks
This question itself is a huge. I will try to give an e-commerce example. In e-commerce application, we will have a multiple micro services for catalog, order, payment, shipping, notification, vouchers etc .. For inventory - we can use nosql database since each item in inventory varied features and we can use catalog service to get the data. For order service, we need ACID compliance so we use SQL database. For session information again we can use nosql database. For notifications service, again nosql database due to horizontal scaling feature. We can use SQL database with multiple read replicas and sharding..

Raj, this is beyond excellent. Very useful for Interviews. Only that 51:02 on the Lambda example, do you think if we use the phrase elastic instead of scaling, it would be helpful ? To your point, Elasticity (versus Scalability) will highlight that memory usage comes down when the requests come down since it the Lambdas (NOT in use) are released.
Sure, however even for auto scaling group the services scale down in case of reduced usage. For example additional EC2s will scale down with reduced usage. Scaling implies both up and down in this case. If you feel comfortable using the term elastic that works too. Hope this helps
HTTP APIs are faster and cheaper version of REST API. The name is confusing, both uses https . There are some feature difference between two, check here - docs.aws.amazon.com/apigateway/latest/developerguide/http-api-vs-rest.html
Hey Chris, yes high level concepts will be general across any clouds. You can always get the course and see if it's helpful to your cloud journey. If you don't like it, you can get your money back within 30 days, no questions asked. I wish you success and luck in your cloud journey irrespective of what course you choose.
Hi Raj, In the difference between API GW and ALB, can API GW be used as a load balancer to equally distribute traffic like Load Balancers or that is the capability that only ELBs have?
API GW can't equally distribute traffic to the backend like ELB, but depending on the endpoint/url it can send traffic to different backends similar to ALBs.
Hey A B M, all these are the part of the first chapter in the Udemy course in the same order as uploaded here, except the Three-Tier one is in the second chapter.

Great content on AWS system design!!!
Hello, I really like your lectures. I want to know if my drawn architecture is correct. Can you please check?
Raj,
Can you add IDP & IDS section as part of System Design course. I noticed you are taking brief about IDP in one of the section. If not possible share CZcams video that will help many of cloud architects.
Good suggestion Surender! I will add it to the course in coming weeks.

Well said Ebbemonster - right tool for the right job!
Great content, Thank you
My pleasure!
Your thoughts are flowing in superbly.. excellent videos Raj. Any tips on how to learn python effectively (from IaC or Serverless standpoint)?

Question here :
So the LB recives the traffic from name servers aka DNS server / route 53 ??
excellent course Raj
Thanks Arun!

Would it be another con of the APIG that you cannot point it to an auto-scaling group ? Or you can ?
Why I just met you bro! LOL , Thank you so much
Better late than never!
good subject
Thanks a Ton, Raj :)
Glad it was helpful Pradeep 🙏
Hi Raj, Hope you are doing good. Will this course help for Devops Architect or Infra architect path or real world projects? Thanks in Advance.
Hey Sharath, it will help for the infra architect and real world projects. Hope your study is going good! Thanks as always for watching my videos.
Excellent stuff!
Thanks for watching 🙏
Around 34:00 isnt it possible to import/export ALB configuration using third party universal tool like Terraform ?

Hi Raj, for Lambda scaling, does the scaling happens for every request? Or it happens only when the Lambda-1 reaches the max RAM limit?
It happens for every concurrent request, irrespective of the memory used per request

@@cloudwithraj That's what even I thought (that Scaling implies both ways) till I was wizened up by a "politically-correct" interviewer ;-)

At 39 mins, what is the difference between http and rest api? As far as I know http is just a protocol used to access rest apis

Hi Raj, I am not getting your system design courses in Udemy for Business. Is there any reason for that ?
Hey Ravi, I have not included the course in Udemy Business. Howevere there is a huge discount going on for next 4 days - bit.ly/3Eku9RH
Thanks Raj! Can you please update this content in your Udemy course on system Design as a section.
