AWS re:Invent 2024 Networking features and use cases
All that you need to know, to architect your new-age cloud network
At AWS re:Invent 2024, Amazon Web Services (AWS) unveiled significant enhancements to its networking services. These updates are designed to simplify application networking and enhance secure connectivity across various environments. I am highlighting the most exciting features and corresponding use cases in Amazon VPC Lattice, AWS Private Link, Amazon Route53 and AWS Cloud WAN
1. Amazon VPC Lattice Enhancements
Amazon VPC Lattice is an application networking service that simplifies the process of connecting, securing, and monitoring service-to-service communications across different compute types. The latest enhancements introduce several key features:
Service Directory and Service Networks
VPC Lattice now offers a centralized service directory, providing a comprehensive view of services owned or shared within your organization. This feature facilitates the creation of service networks with logical boundaries, enabling automatic service discovery and connectivity.
Use Cases:
Ideal for organizations managing multiple services across various accounts and VPCs, this feature streamlines service management and enhances security by applying consistent access and observability policies.
Automatic Connectivity Between VPCs and Accounts
The service manages network connectivity between VPCs and accounts, including network address translation between IPv4, IPv6, and overlapping IP addresses.
Use Cases:
This capability is beneficial for enterprises operating in multi-account environments, simplifying network configurations and reducing the complexity associated with managing inter-VPC communications.
Advanced Traffic Management and Application Layer Routing
VPC Lattice provides advanced traffic management features, including routing based on request characteristics and support for weighted routing, facilitating blue/green and canary-style deployments.
Use Cases:
Organizations can leverage these features to implement sophisticated deployment strategies, ensuring minimal downtime and controlled rollouts of new application versions.
Context-Specific Authentication and Authorization
Integration with AWS Identity and Access Management (IAM) allows for service-to-service authentication and authorization, utilizing familiar IAM capabilities.
Use Cases:
This integration is crucial for maintaining secure communications between services, especially in microservices architectures where multiple services interact frequently.

AWS PrivateLink Enhancements
AWS PrivateLink enables secure, private connectivity between VPCs and AWS services without exposing traffic to the public internet. The recent enhancements include:
Cross-Region Connectivity
PrivateLink now supports native cross-region connectivity, allowing interface VPC endpoints to connect to VPC endpoint services across different AWS Regions within the same partition.
Use Cases:
This feature is beneficial for global organizations that need to access services across multiple regions securely, reducing latency and improving performance for cross-region applications.
Access to VPC Resources
Customers can now use VPC endpoints powered by PrivateLink to access VPC resources such as databases or clusters, whether they reside within the same VPC, different VPCs, or on-premises networks. These resources do not need to be load-balanced and can be shared across teams or with external partners.
Use Cases:
This enhancement facilitates secure, private access to critical resources across various environments, supporting scenarios like multi-tenant architectures and secure data sharing with partners.

Amazon Route 53 Enhancements
Route 53 Resolver DNS Firewall Advanced
AWS unveiled the Route 53 Resolver DNS Firewall Advanced, a feature that enhances DNS security by monitoring and blocking suspicious DNS traffic in real-time. It identifies anomalies in domain and subdomain names queried from your Virtual Private Clouds (VPCs), providing protection against advanced DNS threats such as DNS tunneling and Domain Generation Algorithm (DGA)-based threats.
Use Cases:
Organizations can leverage this feature to safeguard their networks from sophisticated DNS-based attacks, ensuring that malicious domains are blocked before they can cause harm.
Support for Additional DNS Record Types
Route 53 now supports HTTPS and Service Binding (SVCB) record types, which provide clients with improved performance and privacy. These records offer additional information needed to set up connections, such as whether your endpoint supports HTTP/3, enabling faster and more secure client connections. Additionally, Route 53 supports TLS Authentication (TLSA) records, enhancing the security of TLS connections.
Use Cases
These enhancements are beneficial for applications requiring secure and efficient connections, improving user experience by reducing latency and enhancing security.

AWS Cloud WAN Enhancements
Simplified On-Premises Connectivity via AWS Direct Connect
AWS Cloud WAN introduced a new Direct Connect attachment that adds support for automatic route propagation between AWS and on-premises networks using Border Gateway Protocol (BGP). This feature simplifies the process of connecting on-premises environments to AWS, providing a more seamless and efficient networking experience.
Use Cases
Enterprises with hybrid cloud architectures can utilize this feature to streamline connectivity between on-premises data centers and AWS environments, ensuring consistent network performance and simplified management.

Conclusion
These features provide an avenue for organizations to drive towards a more robust, secure and flexible network architecture. It eases multi-region, multi-VPC connectivity, service based networking and centralized networking strategies. I am excited to leverage these new features in my network designs!
