Traditional UDP services require dedicated servers, complex load balancing, and constant infrastructure management. Proxylity UDP Gateway revolutionizes this approach by bringing UDP into the modern serverless ecosystem, allowing you to build highly scalable, cost-effective UDP applications that automatically scale from zero to millions of packets per second.
As a software architect or developer, you understand the challenges of building UDP-based systems:
- Infrastructure Complexity: Managing dedicated UDP servers, load balancers, and auto-scaling groups
- Cost Inefficiency: Paying for idle capacity during low-traffic periods
- Operational Overhead: Monitoring, patching, and maintaining always-on infrastructure
- Integration Friction: Bridging UDP protocols with modern cloud-native services
UDP Gateway eliminates these pain points by providing UDP as a Service - serverless UDP processing that integrates seamlessly with AWS Lambda, Step Functions, EventBridge, and other managed services. Your UDP traffic is automatically captured, routed, and processed using the same event-driven patterns you already use for HTTP APIs.
The examples below demonstrate proven architectural patterns that solve actual business challenges. Each example is production-ready and showcases different aspects of serverless UDP architecture - from simple packet processing to complex multi-modal workflows and secure tunneling solutions.
Whether you're building IoT telemetry systems, real-time gaming backends, DNS services, or VPN solutions, these examples provide the blueprints for implementing UDP services that are:
- ✅ Serverless-first - No infrastructure to manage
- ✅ Auto-scaling - Handle traffic spikes effortlessly
- ✅ Cost-optimized - Pay only for packets processed
- ✅ Cloud-native - Integrate with your existing AWS services
- UDP Packet Counter - An introductory example implemented in Lambda, with a Step Functions variant. Also available in Go, C++, and Python
- Syslog to Cloud - Enterprise-grade log ingestion over UDP, routing to CloudWatch Logs and S3 via Firehose - completely code-free
- Packet Capture - Live, browser-based UDP packet capture with real-time display via AppSync Events. Supports plain UDP and WireGuard ingress with no persistent storage. A deployment walkthrough is available on YouTube.
- SQS Queues - Demonstrates directing UDP packets to SQS queues (standard and FIFO) with configurable delivery options and message attributes
- Kinesis Data Streams - Directs UDP packets to Amazon Kinesis Data Streams with a dynamic partition key derived from the packet payload
- EventBridge Integration - Event-driven UDP processing showcasing how to integrate UDP traffic with AWS's event backbone
- MAVLink to FIFO SQS - Delivers MAVLink v1 and v2 drone telemetry packets to a FIFO SQS queue, demonstrating message deduplication and ordered delivery
- Multi-Region Packet Counter - Demonstrates global UDP processing with region-specific routing and failover capabilities
- Multi-Modal Workflows - Sophisticated example combining HTTP browser interactions with UDP processing and long-running tasks
- Momento Cache over UDP - Superior performance for GET/SET operations for Momento Cache when network connections degrade
- Supabase over UDP - Calling Supabase via UDP from the edge to integrate IoT devices with your web app
- UDP to REST API - Demonstrates using an "inside out" API Gateway to proxy UDP sensor data to Adafruit IO's REST API
- CoAP Time Service - UDP Gateway speaks CoAP — the REST-like protocol purpose-built for constrained IoT devices. Binary packets are decoded to JSON by the
coapformatter before delivery, and re-encoded on the way back. A serverless Step Functions state machine routes requests by URI path and handles Confirmable/Non-confirmable semantics correctly, with zero infrastructure to manage. - CoAP Demo - A production-quality multi-region CoAP API demonstrating the full breadth of UDP Gateway's CoAP support: Observe notifications, Block1/Block2 transfers, async separate responses, and a live exercisable endpoint spanning multiple AWS regions
- DNS Filtering Service - Production-ready DNS resolver with domain blocking and redirection capabilities for custom DNS infrastructure
- WireGuard Echo Service - Serverless solution supporting UDP echo and ICMP ping through encrypted tunnels
- IoT Temperature Display/Sensor - IoT device based on a "Cheap Yellow Display" (1, 2) with WireGuard-ESP32 protected telemetry and time synchronization (NTP)
- RADIUS Authorization and Accounting - Cloud-based RADIUS authentication and accounting system with session state tracking, packet archiving, and multi-region deployment support. Like FreeRADIUS and NPS if they were modern, scalable and had super powers.
