Cutting CPU Utilization by 70% for An AI-Powered Content Research

A U.S.-based AI-powered content research and copywriting platform that simplifies content creation by generating blogs and other materials from relevant keywords.

The Problem Statement

The client was facing high AI hosting costs, migration difficulties, and database corruption. They wanted to achieve cost reduction, improved system performance, and enhanced reliability and security.

Challenges

The AI functionality was driving up significant costs for tech infrastructure.

APIs experienced unresponsiveness and timeouts during sudden spikes in web traffic.

Transitioning from the existing tech stack to a new one was challenging due to a lack of expertise.

The production server was consistently running at 100% CPU utilization.

The analytics dashboard frequently encountered database corruption issues when processing large volumes of data.

DOS and DDoS attacks significantly hindered the manageability and performance of the platform.

Solutions

Our team undertook a comprehensive approach to enhance system performance, security, and reliability. We executed a complete overhaul of the infrastructure, optimized server operations, and implemented advanced technologies for efficient system management.

Created an entirely new platform architecture and set up AWS Infrastructure to manage high infra costs and better scalability.

Implemented an internet-facing load balancer to route traffic to backend EC2 instances, addressing API instability during traffic surges.

Shifted from Amazon RDS to EC2, & implemented Packer with Ansible for smoother deployments & better performance.

Introduced master and slave servers, tuned slave parameters, and implemented IPv6 to alleviate server overload and enhance performance.

Created server backups and a failproof mechanism to ensure database availability, and upgraded Redash to address database corruption issues.

Implemented a VPN on the public server to filter out malicious traffic and integrated Sentry for error tracking to mitigate the impact of DOS and DDoS attacks.

Outcomes

→

50% reduction in overall costs through new platform architecture & AWS Infrastructure.

→

70% reduction in CPU utilization of the production server with optimized server operations and tuning.

→

80% reduction in malicious traffic through the implementation of a VPN and other security measures.

→

100% removal of DOS & DDoS attacks on the servers, ensuring uninterrupted service.
