Edge Server TLS Handshake for Cloud Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud-based services often experience network latency and connectivity issues due to reliance on the Internet for communication, particularly when accessing remote servers across different continents, leading to delays in connection establishment and service delivery.
Innovation Solution
Implementing a system with edge locations that handle Transport Layer Security (TLS) negotiations and data exchanges through private connections, such as Amazon's virtual private cloud (VPC) cross-region peering, to reduce latency and improve connectivity by routing traffic through geographically closer edge servers instead of distant main servers.

Engineering Contradiction Analysis
1Ease of operation
If cloud-based services rely on the Internet as the transport medium for communication, then service delivery can be implemented remotely, but network latency and connectivity issues occur particularly when accessing remote servers across different continents
Solution Approach 1:
The system segments the service delivery infrastructure into multiple geographic regions with edge locations distributed across different continents. Each edge location handles local connection requests independently, dividing the monolithic remote connection problem into smaller regional connections that establish faster and more reliably.
Solution Approach 2:
Edge locations act as intermediary servers between clients and the main service infrastructure. These intermediaries establish local connection points that mediate between remote clients and distant servers, reducing the direct distance and latency of cross-continental connections while maintaining service delivery capability.
2Productivity
If data is transmitted over the public Internet, then infrastructure costs are reduced, but service reliability and quality deteriorate due to network fluctuations and connectivity issues
Solution Approach 1:
The system implements local quality by providing high-reliability private network connections at each geographic edge location. Instead of uniform public Internet connectivity everywhere, each location has optimized local network infrastructure with appropriate connection types (private, dedicated, or high-quality redundant paths) matched to local requirements and capabilities.
Solution Approach 2:
The system dynamically selects and switches between different network paths and connection types based on current network conditions, service requirements, and location characteristics. Edge locations can adaptively route traffic through private connections, public Internet, or hybrid paths, adjusting in real-time to maintain both speed and reliability.
3Reliability
If TLS handshake processes are performed between distant clients and servers across continents, then secure communication is established, but connection establishment delays increase significantly
Solution Approach 1:
The TLS handshake process is segmented into local and remote components. Local handshakes occur between clients and nearby edge locations, establishing secure connections quickly over short distances. Separate handshakes occur between edge locations and the main service infrastructure, isolating the security-critical authentication from the latency-prone cross-continental data transmission.
Solution Approach 2:
Edge locations serve as intermediary TLS endpoints that perform cryptographic handshakes locally with clients. These intermediaries establish secure session keys and authentication credentials locally, then use these established credentials for subsequent data transmission, avoiding repeated long-distance handshakes and reducing overall handshake delay while maintaining security.

AI summary
Methods, systems, and computer programs are presented for lowering network latency for cloud-based services. Service-delivery edge locations allow customers to improve communication-providers public and private network connectivity for improved performance. One method includes operations for performing, by an edge server, a handshake to establish a communication session between a client and a main server, and for exchanging data between the client and the main server via the edge server. The handshake includes exchanging, by the edge server, communication initiation messages with the client, and validating, by the edge server, authentication credentials for the communication session based on the communication initiation messages. The exchanging data comprises forwarding, by the edge server, data requests from the client to the main server through a private connection between the edge server and the main server, and forwarding, by the edge server, data responses from the main server to the client through the private connection.
