Gateway Load Balancers

In this video Adrian explains Gateway Load balancers which help you easily deploy, scale, and manage your third-party virtual appliances. It gives you one gateway for distributing traffic across multiple virtual appliances while scaling them up or down, based on demand

Brilliant. The beauty of this video is it's simple and clear. I am a cloud beginner and can also understand quickly. Thank you for the video.

[@aravindviswanathan6884]

Really outstanding man. I learned many things and even cracked a couple of interviews as well. Thanks a lot

[@manuelolivar3220]

Great video and awesome explanation!

[@gergomeister]

Very nicely and simply explained! Thanks!

[@LearnCantrill]

Glad it was helpful!

[@srirajjayaprakash]

Good job man. was looking for this video. well explained

[@LearnCantrill]

Glad you liked it

[@cd.8749]

Great One! One thing I don't understand well is : Why do we use the GENEVE protocol between GWLB and the security appliances ? Could we don't do it with regular routing ? The packet data won't change only maybe the TTL value.

[@LearnCantrill]

there are some cases when you can't have anything changing, you need a fully authentic stream of data.

[@ishqmaniac]

Brilliant!

[@brkclouddev6025]

sir can you please post all basic fundamentals needed for cloud and devops engineer?

[@LearnCantrill]

I'm putting as much up as i can ... this is all free content so i do it as time allows.

[@jeff946]

Thanks for the video. One thing I don't quite understand is why can't you (or why shouldn't you) just use regular Network load balancers to scale security appliances out?

[@LearnCantrill]

well these are designed for when you want something 'inline' .. so able to analyse traffic in both directions in a transparent way. That's not something you would use a NLB for.

[@simorwimu8357]

Great One!

[@LearnCantrill]

Thanks for the visit

[@jklasfjkl]

Great explanation! One question though @8:11 is there a particular reason why you chose to use an ALB? Couldn't you have picked the same instances as a Target Group directly in the GWLB? Or did I understand it incorrectly, and the Target Groups for the GWLB are actually the appliances?

[@aravindviswanathan6884]

Hi, If we do that then the instances created should be in Public subnets. Also if you create it in a public subnet the application deployed server's public IP address is exposed. To Hide it and also to balance the incoming loads we need to choose either application load balancer or a network load balancer. Then we incorporate either of one to gateway end points.

[@CreaTeach98]

my internert not working when traffic going out through the firewall and its passed, without Nat gateway in catagram VPC.. I think Nat gateway would required for GWLBE to make that as default gateway (NAT Gateway)

[@LearnCantrill]

Not really sure what you’re saying or asking here.

[@CreaTeach98]

@@LearnCantrill i made same topology like 1 vpc for consumer and one for security, when I tried to access internet it's sent to firewall but not getting response... Routing also looking good

[@mohammadchavoshi5568]

[@FernandoLichtschein]

Does't this add latency?

[@LearnCantrill]

Well everything adds latency. Travelling Down a cable adds latency.

[@FernandoLichtschein]

@@LearnCantrill right. I mean more latency that what is acceptable. Hosting an application in a region that has a latency of more than 100 ms is already a problem for some uses,

[@aravindviswanathan6884]

@@FernandoLichtschein Yes it adds latency, To prevent them we can incorporate a global accelerator. Don't worry it is just a fraction of a second. Based on how well we balance the GLB set up we can reduces the latency
