I have to be honest, I was watching a Udemy course about aws cloud solutions architect and it was very comprehensive. But I think your channel has the best explanations for the different services. Easy to understand and to follow, and you also combine different services in your video. You dont just explain what a ec2 instance is, but also mention that it can be combined with a load balancer and co. I mean that combining load balancer and ec2 is pretty basic, but I mean for an entire new beginner, having the connections early helps to connect things faster and I think you do it great. Have should find your channel earlier...
What a Ground Breaking Illustration between EC2 and Lamda Function !!!. I love you man. did you know, by sharing your wonderful knowledge , you also helping our humanity. and for that you have my gratitude. Million Thanks to you !!!. Mat. if you ever happen to be come to Colorado, I take you to dinner. a Restaurant of your Choice. I really mean it.
Mat, Comments like these are what inspire me to keep making videos. Thank you for such kind words of support and inspiration. I never thought of myself as helping humanity, but just a guy trying to help people navigate the world of AWS. I'm glad my videos have been helpful to you and so many others. I'll never stop making them! And if I ever and in Colorado, I'll send you over a message to get together. Cheers Daniel
Just started a new dev job and haven't worked with AWS that much. This video is better than any Udemy course I was given. Really cleared things up for me. Thanks :D
I have been verifying couple of articles for identifying diff between EC2 and Lambda , but this video cleared all my doubts. Lambda server less definition was outstanding
Very useful and informative. One extra thing to consider about lambdas is the cold start time. If a lambda is inactive, there is a (short) delay to spin up the lambda, which an EC2-based solution wouldn't have. Of course, once spun up, the next time the lambda is invoked will be pretty much immediate. Lambdas automatically spin down after a period of inactivity.
Developing a image sharing website, And adding mobile phone apps to it, Is it better to use ec2 or lambda? I dont know a out server security... I use ec2 now, and as for websites, it's quite good. Another important question : If I have lambda, and later want to move everything onto my own server /s, is that easily possible (migration)?! Thanks!
Hey Andy, I'm more of a 'if it ain't broke, don't fix it' kind of guy. If you're getting good performance and are happy with using EC2, I would stick with what you know. I would say for websites, EC2 is a better choice though. For API development (REST, HTTP, etc), Lambdas are a great option. There is room in this world for both! Regarding your second question about migration, I would say that if you anticipate needing to migrate to your own server in the future, leverage Docker + Lambda configuration. This will make it super easy to port over later since the runtime environment is containerized and easily portable to any hardware type. I have a video on Docker + Lambda at this link if you are interested in learning more: ruclips.net/video/q7Zo9I5vhrg/видео.html Hope this helps! Daniel
Thank you for your classes! They are very clear and relevant to help understand AWS services. I have serious doubts on the development of APIs in EC2 with API Gateway services, but I'm not finding references to clarify them. Do you have any video that explains that in detail? Thanks again.
I feel it would have been useful to compare Lambda and Fargate (Function-as-a-Service versus Serverless)… then you might also include ECS as well to show the spectrum of benefits/concerns.
I'm still a bit confused. Your EC2 example was to host websites while your Lambda example was about a REST API. How would you host your (dynamic) website using Lambda? Is that possible?
Hi, it's the same concept - your ec2s can also host rest APIs by using a web server. The ec2 example was not to host to just host websites - it was to build a distributed web application. Lambda accomplishes restful APIs by using API gateway as a dependency. You can host your raw html/CSS/js using something like S3 + cloudfront.
Your way of exaplaning the things is really awesome , if possible could you please share with us api gateway link , I want to watch that video too 👍🏻Thank you for making these useful videos 👍🏻
Nice video as always, though I have a couple of questions: About pricing, say we have 1 on-demand EC2 instance provisioned behind an ALB and ASG with min:1 des:1 max:1 configuration, is this a valid architecture for handling "bursty" workloads than using Lambda? Can we combine the use of EC2 and Lambda at the same time for the same web server? I'm very new to AWS so I don't have an in-depth knowledge about these services yet. Thanks in advance.
@Marcus Erectus for me doesn't make sense to have max to 1 if you really want to scale but you can set rules to scale up say up to 5 or whatever number is depends on your case. for 2nd question, yes we used EC2 with lambda in some use cases
Hi Rohan, Lambda functions suffer from a phenomenon called Cold Start. Cold start is the initial provisioning of the function's code (and dependencies) that need to be loaded prior to execution.
@BeABetterDev Thank you for your video. However, it's not complete. There are plenty of cases where it is best not to use lambda. Example: Cold Function (If your lambda application with very simple code there will have no problem. Lambda will be more faster than EC2 but If your lambda application requires multiple modules [eg. load Layer], it will be slower than EC2).
Hi Jo, Great question. Check out this video for a way to test our your lambda functions locally before pushing your code: ruclips.net/video/AUQRyl1SNcU/видео.html In terms of unit tests, the Lambda is just a function at the end of the day, so you can unit test its functionality like normal in your code base. Hope this helps. Daniel
Nice video :) Just wondering, is it out of the realm of possibilities for you to go over Apache Airflow? Specifically ETLing in it? I heard that a lot of companies will use something like that over just having a bunch of redshift/lambdas as their ETL (especially if it goes over 15min limit anyways or redshift wlm taking too long and timing out lambda)
I don't think the cost comparison is really fair here. On a per-instance basis, EC2 "rent" is based on whether it's on-demand, reserved, or spot, as well as the enormous list of possible choices for resources. Then, if you're using autoscaling (which you probably should), EC2 costs depend on traffic and compute time as well, but in a much less transparent way because it's not as granular as Lambda. Because EC2 is more flexible, there are so many more levers when it comes to adjusting and calculating costs. Lambda is based on just 3 numbers: 1 you choose and the other 2 you can get directly from metrics.
So, serverless didn't mean without servers, instead, it means that the logic from the servers set up is abstracted away from you and managed by AWS. Thank you!
But still, using lambda really like doing drugs. They get very expensive real quick. Unless your company has endless money or you work for Amazon, the budget is gonna be insane.
Hi Jude. Cost really depends - if you have consistent invocations on your application, then I 100% agree with you - Lambdas will *probably* end up costing more. However, if you have bursty or unpredictable invocations, you can save quite a bit of money using Lambdas. I've personally found I was able to shave off ~30% of my infrastructure cost by switching from EC2 to Lambda. Again, this is very use case dependent.

This is one of the Awesome explanations with the most simplistic way of making one understand. Great Job. Rarely we find such tutorials.
Thanks so much Kedar!
Couldn't agree more.
I feel like you’ve been using the Feynman technique because this is one of the best explanations of anything I’ve ever seen. Awesome job!

great great great video! I am starting to learn about AWS and this video cleared up many questions. You earned a like and a new subscriber, thank you!
Thanks Vinicius, and welcome!
This channel is gold!
Thoughtful analysis! Glad you mentioned the cost comparison. Lambdas with something like Serverless Framework even eliminates the clicks :)
Thanks Glenn. Completely agree with serverless framework, they've really made Lambdas even easier to set up and get started these days :)
I would like to recommend Pulumi.

Great video. What about the use case part in terms of on-demand EC2 ? Will they both tie in-terms of advantages or still you prefer lambda ?

Very welcome Krishna, thanks for watching!
2056 MB or 2048 MB (2GB) max for lambda functions? 2056 is a strange number in computer parlance. 2048 (2^11) is not.
I don't think the cost comparison is really fair here. On a per-instance basis, EC2 "rent" is based on whether it's on-demand, reserved, or spot, as well as the enormous list of possible choices for resources.
