Amazon AWS Tutorial #3: Attaching an Elastic Load Balancer to your Auto-Scaling Group

In this video you'll learn how to create an AWS ELB (Elastic Load Balancer) that balances load across your web application. You'll see how easy it is to hook up an Application Load balancer to an Auto-Scaling Group so that you're always guaranteed a healthy website when you do a page load, even if instances are failing in the background.

I'm in the process of migrating our busy web site from a monolithic hosting environment to AWS - and I found this video quite excellent and helpful. I'll have to go back and see the others (and hopefully more to come). Great job.

You rock!

Very well put together tutorials.. you don't mess about and reiterate over the same points time and time again (sadly most other videos do) and you keep it as simple as it needs to be to understand the topic at hand..

Well done! Keep it up..

[eazizi]

You are great. Just want say this your a helpful human in this world thanks appreciate your time

[godfirnon]

Very clear an concise explanation of AWS. This series has been really useful, thanks!

[JamesBos]

Owe you a beer, this is golden! Thanks mate. I have an Linux Admin role interview coming up next week and AWS experience was one of the "nice to have" things on the list. Hopefully it will be nice to have! :) Cheers!

[carstenwieschiolek]

Good job: useful, concise, no-nonsense. Recommended!

[MrVipulLal]

Excellent channel. Maybe you should organise these into playlists

[FunkyAhamed]

Clear explanation and cool... Watched all 3 tutorials.. Thanks for the video... Good job mate !!

[ornous]

very cool intro and looking forward to what comes next. I have been using terraform and as a result didn't know what the interface looked like. Very useful intro. I'd love to hear your thoughts on containers and container orchestration tools (Kubernetes fan here) if and when convenient. it's become so easy to stand up complex infrastructure and custom platforms which makes things so fun and opportunities so common that, on the other hand, I struggle to reshape my vision and appropriately balance my learning. thanks for all your creations from a fellow platform engineer. (:

[AmitKumar-sjgr]

[paingsoe]

Thanks for your AWS series. In addition, How can update every instance on changes such as website update.

[LovePlane]

Thanks man....very useful infos :)
Keep the good work up

[valentinoforever]

Great tutorial but could you please better explain the part around 8:30? How could I create an auto scaling group only for MYSQL (I supposed you're talking about that right?) and another for my PHP script. Thanks!

[bishishtbhatta]

Also, can you make an video on resizing EBS? And show how to attach the resized EBS volume to an ec2 instance?

[AnikBoseace]

when will the next video in this series come out?

[bishishtbhatta]

Hey thanks for the tutorial. Is there any plans for 4th chapter?

[iammanishganguly]

Where can i find the next tutorials.. ?

[은행이자]

Are the Auto scaling configuration lessons for dynamic websites using RDS and php still valid? I'm really looking forward to it.

[danielmeresa]

Nice all the way. I watched the 3 tutorial and implemented based on the guide. Quick question when i do code deployment in my original EC2 instance does the change automatically propagate to all the other 3 ASG instance or I have to deploy in all?
