I have a DNS record created in AWS. For example let's say xyz.com. I have a service running in gcp exposed through a load balancer. Now I want to use aws dns to route traffic to GCP LB. SO I created an alias record in AWS as "demo.xyz.com" and pointed to the ip of gcp load balancer. Still it does not work. Am i missing anything here. Need your help.
Do not use a Route 53 ALIAS record. Use an A resource record specifying the IP address of the Google HTTP(S) Load Balancer.

I have two same task in a service.
this task has the httpd.
It has different IP address 56.XX.XX.12,56.XX.XX.15
I can access both address and get response. 56.XX.XX.12,56.XX.XX.15
Now I try to attach original domain name to this fargate though, from my understanding, I should access to LoadBalancer IP address and LoadBalancer select the target task automatically am I wrong?
If so where can I find the LoadBalancer IP?
From the AWS documentation:
The IP addresses for Classic Load Balancers and Application Load Balancers change over time. Avoid using this information to statically configure your applications to point to these IP addresses.
You should use the provided DNS name of the LoadBalancer instead.

AWS elastic/application load balancers do not have a static IP, they are associated with AWS DNS name to expose application.
From the AWS Docs.
use your DNS service, such as your domain registrar, to create a CNAME record to route queries to your load balancer. For more information, see the documentation for your DNS service.
CNAME records allow you to route traffic to other resources using the domain names. Refer to the docs for more information.
AWS Docs on linking Custom DNS with load balancers: https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/using-domain-names-with-elb.html#dns-associate-custom-elb
I have set ALB with fargate, currently I can access to ALB with dns name like this
myapp-LoadB-FDEWFSOAQXD4-f18c75dd4249a10d.elb.ap-northeast-1.amazonaws.com
However it is said this DNS could be changed.
So I want to give this the Elastic IP
I have experienced connection EC2 and Elastic IP.
In Elasitc IP panel I can choose instance.
However, there is not ALB is listed.
How can I set Elastic IP to ALB ? or am I wrong basically?
Two options here, depending on what kind of direction you are heading:
If you do not like the default DNS name
You can create a DNS record that will point to your load balancer. This means that people would be able to surf to your website by using www.whitebear.com instead of myapp-LoadB-FDEWFSOAQXD4-f18c75dd4249a10d.elb.ap-northeast-1.amazonaws.com
See: Routing traffic to an ELB load balancer - Amazon Route 53
If you really want to attach an ElasticIp to a loadbalancer
There are some use cases where it is really needed to be able to surf to a loadbalancer using a fixed IP. You can achieve this by setting up a Global Accelerator on AWS.
With Global Accelerator, you are provided two global static public IPs that act as a fixed entry point to your application, improving availability.
More information can be found on the AWS Global Accelerator page
If you wish to create a 'friendly' name for an Application Load Balancer, you can create a CNAME record in your Domain and point it to the DNS Name of the Load Balancer.
If you wish to point the Apex of your domain (eg example.com), you can use an Alias in Amazon Route 53 to point to the Application Load Balancer. (It is not normally possible to point a Domain apex to a CNAME record, so the Alias capability of Route 53 will do it for you.)

I have an internal load-balancer in aws and I am able to access it successfully from my office network.
I want to put this behind a generic dns so using Route 53, I created a private hosted zone "domain.com"
and then created A record "project.domain.com" pointing to the lb dns mentioned below:
DNS of internal load balancer -> internal-lb-99999999999999.us-east-1.elb.amazonaws.com/
But now from my office network I tried to access "project.domain.com" and it did not work. AM I missing something?
For the setup i have used in the past we do not have the http:// part in the value of the A record in DNS just the load balancer DNS.
Also have you validated that your VPC has DNS resolution enabled?
how we can include the load balancer of Azure in AWS hosted zones?

Referring to Amazon documentation: Choosing Between Alias and Non-Alias Records
You cannot use Azure Public IP DNS name as an alias here. It seems that only Amazon resources could be used as they can be recognized by Amazon platform.
Normally, you just need to directly use the IPv4 address of Azure load balancer. If the public IP is not static, you may try to create a CNAME record to its DNS name.
I have DNS service provider(web application) as godaddy with CNAME record resolving to DNS value of application load balancer in #AWS. There is requirement where the webapplication request from customer network should route/resolve to specific AWS region based on IP address /subnet of customer. Is there a feature in R53 or load balancer to achive this. I see there is such feature in mircosoft #azure traffic manager to do subnet based routing!. Thank You
It seems you need Route53's geolocation routing, as it works by mapping the IPs from the originating DNS queries to specific AWS resources, like in your case, the loadbalancer.
