Development of a High-Availability Communication Proxy and Self-Provisioning System

Telecommunications

Communication Infrastructure Challenges for Large-Scale Service Providers

The client faces difficulties in managing voice, SMS, instant messaging, and web chat applications due to complex infrastructure requirements, lack of high availability, and manual client provisioning, which limits scalability and reliability of their communication solutions.

About the Client

A large enterprise service provider seeking to enhance its voice, messaging, and unified communications platform with scalable, resilient infrastructure.

Goals for Enhancing Communication System Resilience and Scalability

Implement a high availability proxy service capable of handling large volumes of traffic with automatic failover to minimize downtime.
Develop an automatic client provisioning system to streamline onboarding and configuration processes.
Enhance system resilience to ensure continuous operation during infrastructure failures.
Improve overall system scalability to support expanding user base and increasing traffic demands.

Core Functional System Capabilities for Next-Gen Communication Infrastructure

High availability proxy service with automatic failover to ensure uninterrupted traffic flow.
Automated client provisioning and configuration management for rapid onboarding.
Traffic proxying for mobile applications and web-based communication channels.
Monitoring and analytics capabilities to analyze communication performance and optimize delivery.
Support for open standards to facilitate integration with various communication platforms.

Preferred Technologies and Architectural Approaches

Ruby for backend development

AWS cloud infrastructure for scalability and deployment

Chef for configuration management

Open standards for communication protocols

Load balancing and failover mechanisms

External Systems and Protocols Integration Needs

Backend communication servers (voice, SMS, messaging platforms)
Monitoring and error tracking tools
Cloud storage and configuration management systems

Key Non-Functional System Requirements

System must support at least 250,000 concurrent users or devices.
Failover mechanisms should activate within 30 seconds of a detected failure.
System uptime target of 99.99%.
Secure data transmission with compliance to industry security standards.
Automated scaling to accommodate traffic spikes.

Projected Business Impact of Improved Communication Infrastructure

The implementation of a high-availability, self-provisioning communication proxy is expected to significantly increase system reliability and uptime, reduce downtime-related costs, accelerate client onboarding, and support scalable growth. Targeting an uptime of 99.99%, the system aims to improve overall customer satisfaction and enable the client to serve over 250,000 users reliably.
