How AWS Cloud Front Support Multitenancy Via Sub Domain

Introduction

AWS CloudFront, a Content Delivery Network (CDN), offers robust features to efficiently distribute content globally. When it comes to multi-tenancy, CloudFront can be a cornerstone for delivering scalable and performant applications. This blog explores how to leverage subdomains to implement effective multi-tenancy using CloudFront.

Understanding Multi-Tenancy

Multi-tenancy is a software architecture in which a single instance of an application serves multiple customers (tenants). This approach often leads to increased resource utilization, cost efficiency, and scalability.

Implementing Multi-Tenancy with CloudFront and Subdomains

Choose a Subdomain Structure

Tenant-Specific Subdomains:

Each tenant gets a unique subdomain (e.g., [invalid URL removed], [invalid URL removed]).

Path-Based Segmentation:

Use path parameters within a single subdomain to differentiate tenants (e.g., [invalid URL removed], [invalid URL removed]). While feasible, this approach might not offer the same level of isolation as subdomains.

Create a CloudFront Distribution

Configure a single CloudFront distribution for all tenants.

Obtain a wildcard SSL certificate covering all possible subdomains (e.g., *[invalid URL removed]).

Associate the wildcard certificate with the CloudFront distribution.

Origin Configuration

Determine the origin for each tenant. It could be an S3 bucket, EC2 instance, or other AWS resources.

Configure origin settings for each tenant, including origin domain name, origin path, and custom headers (if required).

Behavior Configuration

Create separate behaviors for each tenant or a default behavior with path patterns to route traffic based on subdomains or path parameters.

Define cache settings, compression, and other relevant parameters for each behavior.

Route Traffic

Use CloudFront's routing capabilities (e.g., path patterns, headers) to direct traffic to the appropriate origin based on the subdomain or path.

Additional Considerations

Tenant Isolation:

Network Level: Consider using VPC endpoints or private link to isolate tenant traffic within AWS.

Application Level: Implement robust tenant isolation mechanisms within your application to prevent data leakage.

Scalability:

CloudFront automatically scales to handle increasing traffic, but monitor performance and adjust cache settings as needed.

Consider using Lambda@Edge for dynamic content and custom logic.

Security:

Regularly review and update SSL certificates.

Implement appropriate security measures for your application and data.
