Got offer from aws, your videos are really helpful. I enjoyed and learned a lot from you.Thanks a lot dada.

Pure Gold this is. Real Practical stuff for SA Interviews

Awesome Raj! Really helpful with real world examples. Thank you!🙏

Wow! You are explaining everything with such clarity. Thank you and Keep it up!

Frankly, when I started seeing your videos, I judged based on my programmed mind, that this is not worth. But I gave a chance to defy my mind and I am now addicted to your videos, I watch atleast one video of yours, and yeah You are a nice being. Please make these videos as many as possible 🙇.

I work in Microsoft Azure mainly. But your videos are you informative and cloud agnostic they can be applied in any cloud solution architecture interviews. Thanks a lot. Really useful content.

Always great content from Raj, my fave AWS teacher !

Thanks Raj for this good content!

Nice one Raj. Thanks.

Thanks a ton for this QAs

Really useful content for AWS serverless learners .... Thanks Raj...!!

Great video! Please keep these "interview question" videos coming! Thanks, Raj!

That's a clear explanation, thank you for helping out!

Hi Raj, another wonderful session. Thanks! In this video you mentioned that we can manage lambda provision concurrency using auto-scaling. But I don't how to do that using AWS Auto Scaling. I would like to request you to kindly create a separate video on this topic.

Can you also make a video on when to use API Gateway over Route 53 for ECS Fargate and EKS?

Very informative . Initially I thought this video is around 30 mins and it will be boring but it is not. It is very interesting. Thanks for the video !!!

Great video. Use a diffuser on your spot light to get rid of the reflection on the whiteboard.

These r some real-world questions pls make more videos on Interview questions. its really helpful

Thanks for the video. Do you have any material around Event bridge integration with eks fargate and/or Lambda integration with eks fargate?

🎯 Key Takeaways for quick navigation: 00:00 *🎯 AWS Lambda Overview* - AWS Lambda is a compute service that eliminates the need for server provisioning. - Features of AWS Lambda: no servers to manage, automatic scaling, high availability, pay-as-you-go. - Use cases of AWS Lambda in various scenarios like API, Alexa, and batch jobs. 01:22 *🚀 Other AWS Serverless Services* - Criteria for AWS serverless services: no servers to manage, auto-scaling, high availability, pay-as-you-go. - Examples of AWS serverless services: API Gateway, SQS, SNS, S3, DynamoDB. 03:10 *🛠 Handling Lambda Cold Starts* - Understanding cold start in Lambda and how containers spin up to load code. - Mitigating cold starts with provisioned concurrency, optimizing code, and leveraging Lambda behaviors. - Strategies like scheduling provision concurrency and optimizing code to reduce cold start times. 08:37 *💡 Using Custom Container Image with Lambda* - Ability to use custom container images with AWS Lambda. - Reusing Lambda advantages with custom container images, but requires slight adjustments for integration. - Benefits of integrating custom container images with Lambda for better service integration and efficient resource usage. 10:16 *📊 Scaling Mechanism: Lambda vs. Fargate* - Lambda scales by spinning up a new instance for each traffic connection. - Fargate operates by handling multiple traffic connections within a container pod. - Contrasting the scaling approach of Lambda (instance-per-connection) with Fargate (multi-connection support and scaling criteria setup). 12:39 *🔄 Lambda vs. Fargate Configurations* - Lambda has a maximum runtime of 15 minutes, while Fargate has no time limit. - Lambda memory limit is 10 GB with 6 CPU cores, unlike Fargate's configurable CPU and memory. - Reusing container images in Fargate is seamless, while adjustments are needed for Lambda integration. 13:35 *🤝 Lambda vs. Fargate Integrations* - Lambda seamlessly integrates with various AWS services like S3, EventBridge, SQS, etc. - Container-based services like Fargate may require additional integration layers for certain service connections. 14:31 *🧠 Configuring Lambda CPU Allocation* - Only memory configuration is possible for Lambda, which indirectly influences CPU allocation. - Increasing memory results in higher CPU core allocation for CPU-dependent workloads. - Monitoring CPU cores can be done through a simple code snippet. 14:56 *🔐 Lambda Function Security* - Lambda function security involves defining who can invoke the function and which AWS services it interacts with. - Utilize Lambda resource policies to control invocation sources and permissions. - Employ dynamic scanning tools for ongoing vulnerability assessment and remediation. 18:00 *🔄 EventBridge vs. SQS for Event Driven Architecture* - EventBridge offers rule-based target invocation, message transformation, archiving, and replay features that SQS lacks. - EventBridge allows direct invocation based on message content, unlike SQS which requires a common handling lambda. - EventBridge provides message archival and selective replay capabilities, enhancing fault tolerance and testing efficiency. 23:21 *🚀 Migrating APIs between Platforms* - APIs can be migrated between different platforms like API Gateway, Apigee, MuleSoft using OpenAPI version 3. - Export APIs as Swagger files for easy migration and import into different platforms. - Use Swagger files along with API Gateway extensions for seamless migration within AWS accounts. 25:41 *🛡️ Integrating API Gateway with EKS and ECS* - API Gateway can be used with EKS (Elastic Kubernetes Service) by routing traffic through Ingress to Kubernetes pods. - For ECS (Elastic Container Service), CloudMap facilitates direct integration with API Gateway for task discovery. 28:14 *✨ Addressing Serverless Challenges* - When asked about serverless challenges, focus on cost and performance optimization as common issues. - Utilize CloudWatch and CloudWatch Insights to monitor lambda memory allocation and optimize performance. - Tools like Lambda Power Tuner and strategies to minimize cold starts can aid in overcoming serverless challenges.

great session. can we have videos on Kubernetes & Network routing

Thanks!

The amount of work you put into each of these videos is amazing. Is there any way to support the channel, I've already subscribed to you. 🙌

Great video but ppt missing like in other video

Really informative videos, just one correction though. EKS is not directly integratable with API gateway, it needs to via NLB and not ALB.

Hi Raj, you mentioned lambdas spin up per connection, so does that mean if I have a subnet mask of 22(1024 ip range) then that means I can only have 1024 people visit my website at one time?

❤

Raj, would you please cover on premise to cloud migration interview questions specially challenges in application assessment & migration solution..

Awesome content dada...Do you provide any training??

Thanks Raj for the content but I want to ask that for this type of questions, do you use STAR format to answer them

Do you have the PDF of these topics?

Pls make some vdo on azure as well..now a days most of the opportunity is all about azure

Hello Raj, I have an interview for an internship in AWS as a Solutions Architect. Can I study this video along with your other video to prepare for the interview? Or do you have a different video for that?

I followed your request to "smash" the like button with a hammer and I broke my screen.... what can I do next?

“Smash it if that’s what you’re into” 💀

Do you have the PDF of these topics?
