AWS deployment example
AWS provides a cloud infrastructure with all the services and computing power you need to provide a reliable cloud deployment platform for Qlik Sense that can perform regardless of unexpected changes in demand, and concurrency.
Qlik Sense single-node deployment on AWS
Components in a typical Qlik Sense single-node deployment on AWS:
- VPC - Virtual Private Cloud. A logically isolated virtual network that shares a common security configuration that you define.
 - Subnet - you need at least one subnet within the VPC. This could be a public, or private subnet.
- Public subnet - subnet with direct access to the internet.
 - Private - a subnet that cannot be reached from the internet.
 
 - RDS - Relational database service. Use this for the repository to provide high availability without the same complexity as a PostgreSQL database.
 - NAT instance (optional) - restricts traffic to private subnets but allows outgoing traffic to the internet. For example, if an EC2 instance is launched inside the private network it can access the internet.
 - Windows Server instance - deployed inside the default subnet to host your Qlik Sense installation.
 - Security groups - act as a virtual firewall controlling which IP addresses can gain access to your instance. Use the Amazon Management Console to create a security group called Qlik Sense.
 - Key pair - a Qlik Sense.pem file that you create and store locally. This file handles authentication when you connect to your AWS instance.
 - IAM - Identity and Access Management. You need IAM to manage the fine-grained permissions required for access to different AWS services.
 - Qlik Sense Server node - a single node deployed on Windows Server inside the default subnet.
 
Deployment options:
- Qlik Sense node in a public subnet with direct Internet access.
 - Qlik Sense node in a private subnet without Internet access.
 
The decision whether to choose a public or private subnet in your deployment depends on your overall solution requirements.
