I'm trying to call my AWS Load balancer which is of type Network Load Balancer with http using its A address. Does AWS Nework Load Balancer support http call, I mean if I call it using http://network-load-balancer-A-name/path, will it forward the request to associated targets.
The AWS Network Load balancer operates at Layer 4 of the OSI stack, it does not know what Http is as that is something at the Application layer or layer 7 of the OSI stack.
If the listener of the AWS Network Load Balancer is configured to listen on Port 80 and is configured to forward traffic from port 80 to the target then yes, setting up a A record with an Alias in Amazon Route53 will forward to the Network Load Balancer then on to the targets. Without the Alias setting in Route53 or using something else and not Route53 would require the IP address of the Load Balancer.

Description:
There is a domain name road.songyangxing.com which resolves to 172.20.12.79. Notice that the ip is private.
We build and run openwrt on Raspberry Pi 4 Model 4. We connect the WiFi lan which the openwrt generates.
Run the command ping road.songyangxing.com, it shows Ping can't find host road.songyangxing.com.
It's OK for pinging the domain name which resolves to a public ip. It's OK for pinging road.songyangxing.com when we change another router.
Question:
How could we let openwrt allow private ip domain name?

This is the first time I have immersed myself in microservices and I am interested in the question of how microservices communicate with each other. I'm going to use traefik as the gateway api and docker for microservices and gRPC as a communication protocol. Can microservices communicate via traefik, or does the microservice need to know the ip address to access? Is there a universal and scalable approach for direct communication? Example of the architecture I want to use
I know that I can set up a network in docker, but then I will have to register a static ip in each microservice, which in my opinion is not the best practice, at least because it will not be possible to use load balancing in this scheme.

I’m changing a server with a bare metal installation with one ip to a new cisco sever with esxi with 3 vm’s, one of them is going to be a nat router to nat the traffic to the other 2 vm’s, is there a way to keep using one just ip ?
I don’t think so, you will need at least 2 one for esxi virtual network to communicate with your network and one for your nat router vm to distribute the traffic via NAT
In fact if your server has CIMC you will need another one to have a remote access to CIMC if you need to recover the server, but it’s not mandatory because you can always connect to CIMC through the console.

Requirement: Cost optimization on Cloud resources
Current Scenario: I am having multiple applications that have their own infrastructure on consists of App Service, MySQL database, function, etc.
Considering these applications will be used by a few people.
My thinking is:
Containerizing all these web applications' servers
1. Use a VM to deploy all the servers
2. Use a Container Instanceto deploy all the servers
3. Use Kubernetes Services to deploy all the servers
Questions: Which approach would be preferable and so that I can expose different IP of servers and map it to its own domain.
For Database,
Apart from using Elastic Pool,
I have no idea how to optimize these databases
I would be glad to have any suggestions thanks.
AKS would be the way to host everything on the same platform and cut costs, but at the same time you'd need to maintain everything you host in AKS.
Elastic Pools do not work for MySQL (only Azure SQL). But you can host MySQL in AKS. To replace functions in AKS you can use KEDA. You'd be able to use host based routing (preferably) or IP based routing to expose your services

I followed the simple instructions for installing the "thin" web server in my ruby application via: http://code.macournoyer.com/thin/
I can see that it is being called when I "start" it. However, while I am able to access the web server using "localhost". I would like to be able to access it using my ip address, or some other way - so that I can send a colleague that's not on my home network to my test app.
while I have fiddled around with some variables (port, host, etc) I am still missing something.
How can I access my thin server from outside of my home network?
Note: I do not have a firewall enabled. - Any thoughts on how to resolve this?
This is more of a network issue than a server setting issue.
You would probably need to set your router to redirect incoming accesses to your computer, how to do will vary from router to router.
In most cases there should be a menu in the router that lets you specify a port, and what internal IP address you want the request to be routed to, set that to your machines LAN IP address, and it should be good to go.
You will probably get a better answer at Server Fault or Super User.
