AWS NLB - Network Load Balancer DEMO | Layer 4 Load Balancing | Comparison

[@cloudnativepizza]

I am really lost for words man, i have browsed numerous articles and videos on the web - and most of them hurry on with explaining the ALB and just throwing a few bits and pieces on NLB... and be done with it. This is the first video i came across, where NLB was actually being drilled in depth... along with uncovering the "No Security Group" mystery. To you Sir.. i take a bow!!!

[@knowledgeindia]

Thank you Nikhil.. I'm sure you will check more playlists on our channel for various AWS topics ✌️✌️✌️

[@kumargauravgut]

One of the best explaination. Articulated pretty well. Crisp, Clear and to the point.

[@DevenderSingh-gc3ch]

Thanks

[@prannoyroy5312]

Finally understood the reason no security groups can be set in NLB is that the connection is not terminated at all from the client, only forwarded..Thanks for covering that aspect!!

Great tutorial. Thank you for the clean and easy explanation. Could you please also tell about the outbound traffic from ec2 instances to outside how its handled in both ALB and NLB scenarios?Does it go via load balancer only and do we need to add those rules or target group explicitly or is it by default it goes via Load balancer?

[@yashhirulkar909]

Thankyou sir. Well explained. But why do we keep webservers in private subnet?

[@kayoutube690]

the good thing for nlb is that the encryption from client to server is enabled compared to alb, alb encryption just happens in client to alb, alb to server traffic is not encrypted.

[@rentacowisgoogle]

That INTRO 😂😂 this channel is fire

[@knowledgeindia]

Sorry, You didn't like it?

[@Anshulmishra160]

Hi Team, U r doing a brilliant job keep it on, Please share ECS container videos also as its having too much requirement in the market

[@pigrebanto]

so for example if a VM is running services on many ports I need to add same VM in multiple target groups, right?

[@bond7535]

What firewall, can I attached to NLB to filterout the malicious traffic? like we can attached WAF with ALB.

[@pardharam3167]

Suppose I launch an internal NLB and targets are two instances in private subnets. How can I assign an static IP to NLB? Please reply.

[@nomads-journey7345]

Sir how you managed to get into both servers to open the ports which you have spinned inside private subnets as i understand to access those servers we either have to use public ec2 and then access it or need to enable nlb ?

[@Hitman45rider_vlogs]

hello I just have one question ? In the start of this video I saw that there are two instances launched in private subnets but my question how to connect to that instances which are in private subnets in order to install apache server on it on the same with windows ?

Yes that's right. I would recommend watching our complete load balancer playlist

[@sunhsiang6644]

[@kiranakolkar3542]

Really appreciate But I have a doubt: how did you get into private instances because I see no public EC2 instance is launched in public subnets.

[@amankumar7915]

What fo you mean by when you say Layer 4 and Layer 7?

[@23834811]

Hi I have one question when creating a LB why we have give the public subnet y not pvt subnet with nat why it won't work

You need to understand role of LB and NAT first. Check our networking playlist if you want to be crystal clear on this.

[@jilight2606]

thanks for a helpful tutorial! Do you've a resource on distributing multiple input files across instances for parallel processing using a load balancer?

[@knowledgeindia]

Please understand LB will not distribute files, it will only send requests. You may choose to store the file which needs to be processed in S3 and then it gets picked from there.

[@jilight2606]

Do you think storing the files in S3 guarantees that LB distributes them across registered instances?

[@knowledgeindia]

S3 will act as storage only.. Your application will have the logic which file to be downloaded.

Huge thanks for this very helpful video..! Can we assign Private Static IP (not EIPs) on NLB's external interface (instead of the external DNS name - which gets auto-generated) ?

[@siddharthgupta6162]

Why is layer 4 load balancer called network load balancer when in OSI layer, layer 4 is Transport layer?

[@jacksonyang6673]

Cause the layer 4 and the layers below it make basic tcp/ip network model. It is actually tcp/ip network load balancer.

Good explanation. I have one issue, Current Project Setup: While on-boarding new client, New Instance has been created and deployed in JBoss Server. New Instance has been create on SQL Server Database. So, Like 100 Clients, 100 Instances deployed in JBoss Server and 100 Instances has been created on SQL Server DB. New Approach can be like, One EC2 Instance for web application, which can be connect to Multiple DB instances. Since it's very hard to migrate All DB Instances to one Instances, How can achieve one EC1 Instance with Multiple DB Instances? I hope, you got my point. - Thanks

You can do that filtering with Security Group of instances (behind NLB). There is no SG at NLB level.

i still don't understand that sir , how do i allow particular ips/network to access my NLB & for internerl NLB , how do we allow NLB to access instances (particular ports)?
