What is the service provided by aws that lets you host domain name systems?

This article walks you through setting up your Amazon Web Services (AWS) account as a resource location you can use with Citrix DaaS (formerly Citrix Virtual Apps and Desktops service). The resource location includes a basic set of components, ideal for a proof-of-concept, or other deployment that does not require resources spread over multiple availability zones. After you complete these tasks, you can install VDAs, provision machines, create machine catalogs, and create Delivery Groups.

When you complete the tasks in this article, your resource location includes the following components:

• A virtual private cloud (VPC) with public and private subnets inside a single availability zone.
• An instance that runs as both an Active Directory domain controller and DNS server, located in the private subnet of the VPC.
• Two domain-joined instances on which the Citrix Cloud Connector is installed, located in the private subnet of the VPC.
• An instance that acts as a bastion host, located in the public subnet of your VPC. This instance is used to initiate RDP connections to the instances in the private subnet for administration purposes. After you finish setting up your resource location, you can shut down this instance so it is no longer readily accessible. When you must manage other instances in the private subnet, such as VDA instances, you can restart the bastion host instance.

Task overview

Set up a virtual private cloud (VPC) with public and private subnets. When you complete this task, AWS deploys a NAT instance with an Elastic IP address in the public subnet. This enables instances in the private subnet to access the Internet. Instances in the public subnet are accessible to inbound public traffic while instances in the private subnet are not.

Configure security groups. Security groups act as virtual firewalls that control traffic for the instances in your VPC. You add rules to your security groups that allow instances in your public subnet to communicate with instances in your private subnet. You will also associate these security groups with each instance in your VPC.

Create a DHCP options set. With an Amazon VPC, DHCP and DNS services are provided by default, which affects how you configure DNS on your Active Directory domain controller. Amazon’s DHCP cannot be disabled and Amazon’s DNS can be used only for public DNS resolution, not Active Directory name resolution. To specify the domain and name servers handed to instances through DHCP, create a DHCP options set. The set assigns the Active Directory domain suffix and specifies the DNS server for all instances in your VPC. To ensure Host (A) and Reverse Lookup (PTR) records are automatically registered when instances join the domain, you configure the network adapter properties for each instance you add to the private subnet.

Add a bastion host, domain controller, and Citrix Cloud Connectors to the VPC. Through the bastion host, you can log on to instances in the private subnet to set up the domain, join instances to the domain, and install the Citrix Cloud Connector.

Task 1: Set up the VPC

1. From the AWS management console, select VPC.
2. From the VPC Dashboard, select Start VPC Wizard.
3. Select VPC with Public and Private Subnets and then Select.
4. Enter a VPC name and change the IP CIDR block and Public and Private subnet IP ranges, if necessary.
5. If a NAT gateway is selected, select Use a NAT Instance instead.
6. For the NAT instance, specify the instance type and the key pair you want to use. The key pair enables you to securely connect to the instance later.
7. In Enable DNS host names, leave Yes selected.
8. Select Create VPC. AWS creates the public and private subnets, Internet gateway, route tables, and default security group.

Note:

Changing the name of an AWS Virtual Private Cloud (VPC) in the AWS console breaks the existing hosting unit in Citrix Cloud. When the hosting unit is broken, you cannot create catalogs or add machines to existing catalogs. From Known Issue: PMCS-7701

Task 2: Configure security groups

This task creates and configures the following security groups for your VPC:

• A security group for the NAT instance.
• A public security group, with which instances in your Public subnet will be associated.
• A private security group, with which instances in your Private subnet will be associated.

To create the security groups

1. From the VPC Dashboard, select Security Groups.
2. Create a security group for the NAT instance. Select Create Security Group and enter a name tag and description for the group. In VPC, select the VPC you created earlier. Select Yes, Create.

   Which AWS service allows you to configure a DNS record set?

   With Amazon Route 53, you can create and manage your public DNS records. Like a phone book, Route 53 lets you manage the IP addresses listed for your domain names in the Internet's DNS phone book.

   Which service in AWS can allow you to buy a domain name?

   Register a new domain using Amazon Route 53 in the AWS console.

   What is domain name system in AWS?

   DNS, or the Domain Name System, translates human readable domain names (for example, www.amazon.com) to machine readable IP addresses (for example, 192.0. 2.44).

   Which AWS service can be used to host a static website?

   AWS Amplify provides fully managed hosting for static websites and web apps. Amplify's hosting solution leverages Amazon CloudFront and Amazon S3 to deliver your site assets via the AWS content delivery network (CDN).
