6. How AWS Global Accelerator Works
AWS Global Accelerator simplifies traffic routing, enhances application performance, and ensures high availability. Here's a detailed explanation of how it works:
6.1 Accelerator Configuration
An accelerator is the core component of AWS Global Accelerator, designed to direct traffic from users to application endpoints efficiently. The configuration includes:
Listeners
Define the protocol (TCP/UDP) and ports for incoming traffic.
Each listener can have rules that dictate how traffic is processed, such as prioritization or specific endpoint group mappings.
Example: A listener might accept traffic on port 80 for HTTP or port 443 for HTTPS.
Endpoint Groups
Represent a set of endpoints located in a specific AWS region.
Each group is associated with a listener and can have unique settings, such as traffic weightings or health check configurations.
Endpoints within these groups can include:
Elastic Load Balancers (ALB or NLB)
Amazon EC2 instances
On-premises servers or other custom routing configurations.
Traffic Weights
Endpoint groups can have weights assigned to determine the proportion of traffic routed to each group.
This allows traffic distribution across multiple regions based on business requirements or performance needs.
6.2 Traffic Routing
AWS Global Accelerator uses intelligent routing policies to ensure efficient delivery of traffic:
Geographic Proximity: Routes users to the nearest endpoint group to reduce latency and improve performance.
Weighted Traffic Distribution: Allocates traffic across endpoints or regions based on configured weights.
Endpoint Health: Prioritizes sending traffic to healthy endpoints, ensuring uninterrupted service.
AWS Private Network Backbone: All traffic is routed through AWS’s secure and highly performant private global network, bypassing the less reliable public internet.
6.3 Health Checks and Failover
To maintain high availability and reliability, AWS Global Accelerator continuously monitors the health of configured endpoints:
Health Checks
Performed at regular intervals to verify endpoint availability and responsiveness.
Check parameters include latency, connection status, and application responsiveness.
Automatic Failover
If an endpoint becomes unhealthy or unavailable, traffic is instantly rerouted to other healthy endpoints within the same group or another region.
This minimizes downtime and ensures a seamless user experience.
6.4 Integration with AWS Services
AWS Global Accelerator integrates seamlessly with other AWS services to provide a comprehensive traffic management solution:
Elastic Load Balancers (ALB/NLB)
Directs traffic to applications behind Application Load Balancers (ALB) or Network Load Balancers (NLB), supporting dynamic scaling and failover.
Amazon EC2 Instances
Enables routing directly to individual EC2 instances for specific workloads.
Amazon S3
While typically used for static content delivery via Amazon CloudFront, Global Accelerator can direct traffic to S3-based applications in certain architectures.
Hybrid Environments
Supports routing traffic to on-premises data centers or applications using AWS Direct Connect or AWS VPN.
Amazon CloudFront
Works in tandem with CloudFront for content delivery, with Global Accelerator handling dynamic traffic and CloudFront serving static assets.
Example Workflow
A user requests a resource via a static IP assigned by AWS Global Accelerator.
The request passes through the listener and is routed to the appropriate endpoint group based on location, traffic weight, and health status.
The service performs a health check on endpoints within the group.
Traffic is delivered to the optimal endpoint, ensuring low latency and high availability.
6. Pricing for AWS Global Accelerator
AWS Global Accelerator pricing is designed to be flexible, based on the resources used, and to offer cost efficiency as customer demands fluctuate. Below is an expanded explanation of how pricing works in 2024
6.1 Pricing Components
Global Accelerator Fee
AWS Global Accelerator charges a monthly fee for the accelerator itself, which covers the provisioning of the accelerator and its listeners.
Fixed monthly fee: There is a fixed monthly charge for each accelerator.
Example: If you have one Global Accelerator with two listeners, the monthly fee might be, say, $18 per month for the accelerator, plus an additional $5 per listener.
Total cost: $18 + (2 listeners x $5) = $28 per month.
Data Transfer Costs
The data transfer pricing is based on the amount of data transferred through the Global Accelerator.
Data transfer pricing is charged per GB for traffic coming into the accelerator and for the traffic forwarded to your endpoints.
Traffic charges apply based on the location of the source and destination (whether data is within the same AWS region or across regions).
Example:
In-region data transfer: If your traffic is routed within the same AWS region, you might be charged $0.02 per GB.
Cross-region data transfer: If traffic is routed from one region to another, the cost might be higher, say $0.10 per GB.
Static IP Address Fees
AWS Global Accelerator assigns static IP addresses to each accelerator. There is an additional charge for each IP address allocated.
Static IP allocation: Typically, AWS Global Accelerator charges for $0.025 per IP address per hour.
Example: If you allocate two static IP addresses for your accelerator, the monthly charge would be $0.025 per hour x 2 IPs x 24 hours/day x 30 days = $36 per month for two IP addresses.
Endpoint Group and Endpoint Weights
The pricing for endpoint groups depends on the weight of traffic distributed and the number of regions or endpoints involved.
Endpoint group weight distribution: You can distribute traffic based on weights assigned to different endpoint groups. If an endpoint group receives more traffic, it may incur higher data transfer costs.
Example: If you have two regions with different weightings (e.g., Region A with a weight of 70% and Region B with 30%), the amount of traffic routed to each region will affect the cost based on data transfer charges in those regions.
6.2 Example Pricing Scenarios
Scenario 1: Small Business Using a Single Region
You configure one AWS Global Accelerator with two listeners (HTTP and HTTPS), and one static IP.
The traffic is routed within a single region (in-region).
Monthly Charges:
Global Accelerator fee: $18
Two listeners: $10 (2 x $5)
Data transfer: 10 GB in-region = 10 GB x $0.02 = $0.20
Static IP allocation: $0.025 per IP x 2 IPs x 24 hours/day x 30 days = $36
Total monthly cost:
$18 + $10 + $0.20 + $36 = $64.20
Scenario 2: E-commerce Platform Using Multiple Regions
An e-commerce business uses AWS Global Accelerator for a global audience. The accelerator has multiple listeners (HTTP, HTTPS, and WebSocket), and it routes traffic across two AWS regions.
You have 5 GB of data transfer in-region (for Region A) and 20 GB of cross-region traffic (from Region A to Region B).
Monthly Charges:
Global Accelerator fee: $18
Three listeners: $15 (3 x $5)
Data transfer:
5 GB in-region = 5 x $0.02 = $0.10
20 GB cross-region = 20 x $0.10 = $2.00
Static IP allocation: $36 (2 IPs)
Total monthly cost:
$18 + $15 + $0.10 + $2.00 + $36 = $71.10
Scenario 3: High-Traffic Streaming Service
A video streaming service using AWS Global Accelerator routes high-traffic across multiple global regions. The service has 10 listeners (HTTP, HTTPS, and WebSocket for different video resolutions) and routes 100 GB of cross-region data.
Monthly Charges:
Global Accelerator fee: $18
Ten listeners: $50 (10 x $5)
Data transfer:
10 GB in-region = 10 x $0.02 = $0.20
100 GB cross-region = 100 x $0.10 = $10.00
Static IP allocation: $36 (2 IPs)
Total monthly cost:
$18 + $50 + $0.20 + $10.00 + $36 = $114.20
6.3 Flexible Pricing Models for 2024
In 2024, AWS has introduced more flexible pricing models for AWS Global Accelerator:
Pay-as-you-go:
For businesses with fluctuating traffic demands, AWS offers a flexible pricing model where you only pay for the resources you use, such as data transfer, static IPs, and listeners.
This model helps reduce costs during low-traffic periods.
Savings Plans:
AWS now offers Savings Plans for customers committing to long-term usage. This can help businesses save on accelerator fees and data transfer charges by committing to a certain level of usage over a one- or three-year period.
