In the video, I discussed serverless computing, clarifying that it doesn't mean no servers are involved. I highlighted the caution needed when adopting it and explained its purpose. Real-world use cases were explored, such as cost efficiency, scalability, and automation benefits. The shift from traditional server provisioning to on-demand scaling was emphasized. Serverless offerings from major cloud providers and the advantages of focusing on core business logic were covered. Examples included chatbots, online judges, vending machines, and cron jobs, showcasing the versatility and cost-effectiveness of serverless architecture.

From were you should start or what should be the main steps when migrating from a traditional infrastructure to a serverless one? What should be the things that are taken into account?

[@vikasbhutra9400]

Perfect Video for all those who want to start learning about serverless computing. Great Explanation !!🙌

[@psiddharth99]

Thanks Arpit! This video cleared all my doubts related to Serverless Architecture.

[@kalpeshmali8498]

Very informative and indepth video arpit sir i hope you get more recognition from the comunnity you deserve more students and more subscribers sir Thanks for the Video :)

[@techwithnaga]

Thanks Arpit

[@JenilCalcuttawala]

Awesome explanation as always! GCP Cloud Functions Gen 2(in Pre-GA as of now) will be able to support longer running tasks (upto 60 minutes).

[@arsyaswanth5]

Best explanation for serverless architecture.

[@ABHIJAYPATNE]

Superlike! The practical use case was very helpful.

[@theSDE2]

Awesome video. Learning alot and started taking notes as well. 😎

[@AjitSingh-hd9op]

Very insightful and useful. Thanks for sharing!

Very informative. Thanks alot 🎉🎉

Serverless cloud services can be utilized for many use cases not limiting to these 5. Many companies have already moved most of their services to serverless. As you mentioned, SQS, SNS, DyanamoDB, AppSyn are all serverless. For startups this is a very good thing as they wouldn't have to worry about having DevOps team and time to market is faster. Any business that doesn't require 24*7 demand, serverless would be a great pick.

Can you also share the presentations used in the video as attachment below?

[@janardhansharma9094]

Your videos are awesome !!! BTW, what tool do you use for the presentation ? (I mean, both hardware and software)

[@AsliEngineering]

Description has the information 😃

Great Video, Arpit !! Let's say, I want to run a script for every 5 seconds which GET's status from a REST Endpoint. Responses received from the endpoint will be either SUCCESS or FAILED. If response received is FAILED then I will trigger someother workflow. Do you think opting Serverless would be a good usecase, given that this should run for every 5 seconds ?

[@mr_code312]

yes server less would be fine for these

[@martinabeita8852]

Awesome explanation but what would happen if a serverless architecture comes under DDos attack then it can costs you thousands of dollars right?

[@AsliEngineering]

Yes. Cloud providers typically prevent that.

[@martinabeita8852]

@@AsliEngineering okk thank you for the info

[@swagatochatterjee7104]

Can you please explain why online-judge is a good case here? If you send the whole testcase set, your code may take more than 15 minutes to run all the test cases. So lambda may timeout. Moreover many serverless systems doesn't give access to internal OS level constraints, which are absolutely important in cases, say when you don't want anyone to run a fork(). I'm curious to know how such cases can be implemented in serverless?

[@AsliEngineering]

1. you will pick serverless only if your eval will complete within 15 mins. 2. you do not need fancy OS level privileges to fork a new process on serverless env

[@swagatochatterjee7104]

@@AsliEngineering sorry if I misplaced my question. 2.I meant how can I place OS level privileges in Serverless Runtime so as to prevent certain syscalls like `fork`. I don't want to run fork, I want to block it. 1. How can I design serverless patterns when I want to run code against multiple test cases which very well may take more than 15 mins collectively, but individually may take minutes? Then shoukd there be like invocation of each lambda for each test case? If so how are we expected to collate all the results and send back a response?

Bro can we do dsa in python as it's my main language and built project with python and then learn lld and hld

Yes. We can.. totally.
