Revolutionizing Infrastructure Security and Scalability: A Comprehensive AWS Solution

Infrastructure & DevOps Modernization

Learn how we helped a video surveillance management system company transform their cloud infrastructure, resulting in reduced operational costs, improved security, and enhanced customer experience.

The customer, an industry leader in video surveillance management systems, partnered with Caylent to transform their cloud infrastructure. Their software serves thousands of clients across multiple sites, from small businesses to large enterprises.

Challenge

The customer faced several critical infrastructure hurdles that were impacting their ability to scale and serve customers efficiently. Their infrastructure components, including Gateway, Proxy, and VPN services, were decentralized, leading to complex management and increased operational overhead.. The existing DynamoDB implementation used a single-tenant model, resulting in escalating costs as the customer base grew. The lack of a centralized authentication system created security vulnerabilities and management difficulties across their platform. Furthermore, their support team struggled with troubleshooting remote access controls, lacking proper tools for efficient diagnosis and resolution.

Solution

Working with Caylent, The customer implemented a comprehensive transformation strategy that addressed each core challenge. The team consolidated the Gateway, Proxy, and VPN services into a centralized architecture, implementing robust failover capabilities between AWS Outposts and cloud environments. The database architecture was completely redesigned, moving from single-tenant to multi-tenant DynamoDB implementation to optimize costs and improve scalability. A new authentication system was deployed using AWS Cognito, providing centralized security controls and enhanced features such as MFA. The team also developed a sophisticated desktop application for remote access testing, incorporating comprehensive diagnostics tools for both initial setup and ongoing troubleshooting needs. This solution leveraged key AWS services including Cognito, DynamoDB, EC2, Lambda, and API Gateway to create a robust, secure, and scalable infrastructure.

1. Infrastructure Security

  • Re-architecture of Gateway, Proxy, and VPN services
  • Implementation of failover capabilities between AWS Outposts and AWS cloud
  • Design of two distinct solutions:
  • All-in-one VPN application solution
  • Enterprise-ready solution supporting customer VPN/networking integration

2. Database Optimization and Compliance

  • Migration from single-tenant to multi-tenant DynamoDB design
  • Cost optimization through improved architecture
  • Implementation of efficient data schema and application integration

3. Authentication Modernization

  • Centralization of authentication using AWS Cognito
  • Implementation of enhanced security features including MFA
  • Integration with existing applications and systems
  • Establishment of clear authorization workflows

4. Remote Access Testing Tool

  • Development of a standalone desktop application with two operational modes:
  • Pre-Flight: Initial VPN service setup verification
  • Post-Flight: Connectivity troubleshooting
  • Integration of multiple testing capabilities:
  • Windows Defender verification
  • DNS resolution checking
  • Connectivity validation
  • OpenVPN component verification
  • Technical Implementation

Results

The transformation delivered substantial improvements across all aspects of The customer' operations. Infrastructure management costs decreased significantly through the new multi-tenant database architecture and centralized services. System security saw marked improvement with the implementation of standardized authentication controls and enhanced monitoring capabilities. Customer support efficiency increased dramatically thanks to the new remote access testing tool, resulting in faster issue resolution and improved customer satisfaction. The platform's scalability and reliability showed significant enhancement, with the new architecture successfully handling increased customer load while maintaining performance. The modernized infrastructure also positioned The customer for future growth, providing a solid foundation for expanding their service offerings and customer base. Most importantly, the project achieved its core objectives of reducing operational costs, improving security, and enhancing the overall customer experience while maintaining service quality throughout the transition.
