AWS Global Accelerator

Overview of AWS Global Accelerator

  • AWS Global Accelerator is a networking service that enhances application performance and availability by directing user traffic through AWS's global network infrastructure.

Key Concepts

  • Analogy to Content Delivery Networks (CDN):

    • AWS Global Accelerator can be compared to express lanes on pizza delivery routes that ensure faster delivery by bypassing traffic. It finds the optimal pathway to the nearest regional endpoint.

Benefits of AWS Global Accelerator

  • Improved Performance:

    • Utilizes Amazon's congestion-free global network, resulting in a smoother and faster user experience with up to a 60% increase in throughput.

  • Simplified Traffic Management:

    • Provides two global static public IPs as a fixed entry point, simplifying traffic management across regions without complex DNS configurations.

  • Security and Reliability:

    • Enhances application security and protects against DDoS attacks.

    • Automatically reroutes traffic to the nearest available regional endpoint if issues arise.

  • Consistent User Experience Globally:

    • Ensures consistent application response time worldwide by utilizing intelligent routing to the best performance endpoint.
