AWS re:Invent 2023 - Building Hybrid Network Connectivity with AWS (TNC217)

Summary

• The session covered the journey from on-premises networking to hybrid networking with AWS.
• The speaker shared their personal career path, humorously highlighting the challenges and misconceptions in networking.
• Gartner statistics were cited, showing a high percentage of enterprises with a cloud-first strategy still have on-premises presence, indicating a need for hybrid solutions.
• Traditional network complexities were discussed, including data centers, remote workers, branch offices, and warehouses needing to connect to AWS.
• The speaker introduced AWS's global infrastructure, including regions and points of presence (POPs), and the upcoming Canada West region.
• A use case called "Any Company" was presented, which included two data centers aspiring to migrate to AWS and scale globally, with a need for encryption.
• Site-to-Site VPN was initially suggested for connectivity, with details on how to set up connections and the limitations of VPN bandwidth.
• AWS Transit Gateway was introduced as a solution to simplify connections and support multicast and ECMP for higher bandwidth.
• Global Accelerator was discussed as a means to achieve consistent performance by leveraging AWS's backbone network.
• AWS Client VPN was explained for remote worker access to cloud workloads, with authentication methods and best practices for setup.
• Direct Connect was covered as a method for cost-effective and consistent performance, including MACsec support for encryption.
• The speaker addressed various requirements such as connecting branch offices, encryption needs, and high availability for Direct Connect.
• AWS Cloud WAN (Cloud One) was introduced as a solution to simplify network management across AWS regions and accounts.
• DNS resolution in a hybrid environment was explained using Route 53 Resolver endpoints and sharing rules with AWS Resource Access Manager (RAM).
• The session concluded with a summary of the learning points and resources for further learning on AWS networking.

Insights

• Hybrid networking is a critical component for enterprises that maintain both on-premises and cloud infrastructure.
• AWS provides a comprehensive set of services to address the complexities of hybrid networking, including VPN, Direct Connect, Transit Gateway, Global Accelerator, and Cloud WAN.
• The use of AWS's global infrastructure can significantly improve performance and reduce latency by leveraging AWS's backbone network instead of the public internet.
• AWS Transit Gateway is a pivotal service that simplifies network management by reducing the number of connections needed and supporting advanced networking features.
• AWS Cloud WAN (Cloud One) offers a managed network solution that can automate the setup and management of networking across multiple AWS regions and accounts, which is beneficial for large-scale deployments.
• DNS resolution in hybrid environments can be managed effectively using AWS Route 53 Resolver endpoints, with the ability to share rules across accounts and regions using AWS Resource Access Manager.
• The session highlighted the importance of understanding the various AWS networking services and how they can be combined to meet specific enterprise requirements, such as encryption, high availability, and simplified management.
• The speaker's use of humor and real-world examples helped to demystify complex networking concepts and make the session more engaging for the audience.
