How AWS CloudFront Helped Slash Latency by 80%

A prominent player in the global energy sector—managing operations in oil & gas, renewables, and infrastructure—faced growing challenges in delivering critical engineering data and real-time dashboards to teams across continents. To ensure speed, reliability, and efficiency in content distribution, the company turned to Amazon CloudFront, AWS’s content delivery network (CDN), to accelerate content delivery and enhance operational efficiency.

• High Latency: Remote field teams and offshore units experienced significant delays accessing project dashboards and documentation.
• Server Overload: Centralized systems were strained during peak activity periods, such as project launches or incident responses.
• Inconsistent User Experience: Energy analysts, engineers, and field personnel faced varying load times based on geographic location.
• Limited Caching Flexibility: The legacy CDN offered limited control over caching dynamic operational data and engineering content.

The energy company adopted Amazon CloudFront with a strategic implementation that included:

• Global Edge Network: Leveraged CloudFront’s 600+ edge locations to deliver content closer to geographically distributed teams and sites.
• Custom Cache Behaviors: Optimized delivery by configuring caching for both real-time dashboards and static engineering files.
• Lambda@Edge: Used edge-based serverless logic to tailor access control and personalize data views by region and role.
• Origin Shield: Enabled Origin Shield to reduce load on core infrastructure, ensuring higher availability and faster response times.
• Real-Time Monitoring: Integrated CloudFront logs with Amazon CloudWatch for continuous performance tracking and tuning.

• 80% Reduction in Latency: Page load times dropped from 2.5 seconds to 0.5 seconds globally, improving access to operational tools.
• 95% Cache Hit Ratio: Reduced dependency on origin systems, boosting reliability and responsiveness during mission-critical tasks.
• 40% Lower Bandwidth Costs: Optimized data flows resulted in fewer origin requests and decreased outbound traffic expenses.
• Boosted Operational Efficiency: Quicker access to dashboards and engineering data led to a 25% increase in user engagement and a 15% drop in operational delays.

By adopting AWS CloudFront, this energy company enhanced its digital infrastructure, enabling real-time collaboration, quicker access to operational data, and consistent performance across all global units. This case demonstrates the crucial role of CDN technologies in driving agility, responsiveness, and cost-efficiency in the energy sector’s digital transformation journey.
