Introduction to AWS Global Accelerator

Back in 2018, Amazon Web Services saw a big problem for global companies. They needed their applications to work just as well for a user in Tokyo as they did for a user in Ohio. The old way of doing things, using DNS to send users to the “closest” server, was not cutting it. The public internet is just too unpredictable.

This is why they built the AWS Accelerator. It was made for any business with users spread across the globe. Think online games, video chat, e-commerce stores, or any critical business software. It’s a key part of the AWS world. It sits in front of your app and directs users to the best possible place.

So, what is Global Accelerator in AWS compared to old-school DNS routing?

Traditional DNS routing: When a URL is entered, DNS identifies the IP address of the server. It can try to pick a server that is geographically close to you. However, you have no control over the route your data travels on the public internet. It might go through congested areas, slowing things down. If a server fails, it can also take time for the DNS entry system to update and send users elsewhere.
AWS Global Accelerator: This tool changes the game significantly. It gives you two static IP addresses. These addresses don’t live in just one place. They exist at many AWS network locations around the world. When a user connects, they are sent to the nearest AWS entry point. From there, their traffic zips across the private AWS network. It avoids the public internet chaos and finds the healthiest, fastest path to your app.

How AWS Global Accelerator operates

So how does this service pull it off? The technology behind Amazon Global Accelerator is smart, but the concept is simple. It is all about giving your user traffic a better road to travel on. Let’s look at the key parts.

The function of anycast IP addresses

The magic starts with something called anycast IP addresses. When you activate the AWS accelerator, you receive two static IP addresses. These IPs are special. Multiple AWS edge locations across the globe broadcast them simultaneously.

Here’s a simple breakdown of the process:

A single IP, global reach: AWS advertises the same IP address from locations across North America, Europe, Asia, and beyond.
The closest on-ramp: User requests are automatically directed to the closest AWS edge location. This is like getting on the highway at the closest on-ramp instead of driving through city streets.
The express lane: Once on the AWS network, the traffic travels on a private, optimized path directly to your application.

This method has big benefits:

Simple DNS: You have two IPs that never change. You can update your backend servers, move regions, or scale up without ever touching your DNS settings. This makes management much easier.
Fixed entry point: Users always connect to the same addresses. This is a huge help for customers who need to approve specific IPs in their firewalls for security or compliance.
Less delay: Getting traffic onto the AWS network fast is the key. It cuts the travel time between your user and your app.

For many companies, especially in finance or healthcare, having fixed IPs is not just a nice-to-have; it’s a requirement. AWS Global Accelerator provides this stability without sacrificing global performance.

Intelligent path optimization

After user data reaches the AWS network, the accelerator routes it like a GPS system. It constantly checks all possible routes for congestion, slowdowns, and outages. The public internet is unpredictable, and the shortest path isn’t always the fastest.

AWS Global Accelerator finds the best available path in real-time. It collects data on network performance and uses it to steer your traffic around trouble spots. This guarantees your data takes the most efficient and reliable route. It’s a huge improvement over the public internet, which often sends data on a longer, slower journey.

Automatic rerouting through health monitoring

Great performance means nothing if your application is down. High availability is built into AWS Global Accelerator. It constantly runs health checks on your application endpoints, like your servers or load balancers.

Here is how the failover process works:

Constant checks: The AWS Accelerator sends little signals to your endpoints to make sure they are running.
Spotting trouble: If an endpoint stops responding, it is marked as unhealthy right away.
Fast rerouting: Traffic is instantly and automatically sent to the next closest healthy endpoint.

This all happens in seconds. Your user probably won’t notice a thing. If your main server in one region goes down, traffic will just flow to your backup region. This automatic rerouting enhances reliability and helps reduce downtime.

Core capabilities of AWS Global Accelerator

Now we know how it works. But what is AWS Global Accelerator used for in real business? Let’s explore the core features that distinguish it in global traffic management.

Boosted application responsiveness

The number one job of the Amazon Global Accelerator is to make your application faster. It uses the private AWS backbone to bypass the unpredictable slowdowns of the public internet. This means lower latency and quicker data transfers.

For some applications, speed is everything:

Online games: Even a brief delay can disrupt the gaming experience. AWS Global Accelerator helps make sure gameplay is smooth and fair for everyone.
Video and voice calls: It reduces jitter and dropped packets. This leads to clearer calls and smoother video, making remote meetings less frustrating.
Stock trading: In finance, every millisecond counts. Low latency is vital for trading platforms to stay competitive.

High availability and reliability

Reliability is one of the key benefits offered by AWS Global Accelerator. It keeps your app online in a few key ways:

Backup plans: It uses multiple edge locations and lets you set up endpoints in different AWS Regions. This means there’s no single point of failure. If one part has a problem, others are there to take over.
Instant failover: As we saw, it automatically moves traffic away from unhealthy endpoints. This switch happens in under a minute, so your app stays available during outages.
Uptime guarantee: AWS provides a Service Level Agreement (SLA) that guarantees 99.99% availability. This is a strong promise for your important applications.

Building this kind of availability yourself would be complex and expensive. AWS Global Accelerator provides this capability by default.

Streamlined management of user traffic

This tool gives you one central place to control your global traffic. From the AWS console, you can decide exactly how your users are routed.

Easy management features include:

Endpoint weights: You can send more traffic to one region and less to another. This is great for testing a new feature or balancing the load on your servers.
Traffic dials: You can turn up or down the traffic going to a whole AWS Region. This helps with controlled rollouts, A/B testing, or moving traffic away during maintenance.

These controls empower you to confidently manage your global operations.

Built-in DDoS attack mitigation

Security is always a concern. Your applications are protected from DDoS attacks with AWS Shield Standard. It is automatically included with AWS Global Accelerator at no additional charge.

Here is how it keeps you safe:

Spreading out attacks: The anycast IP addresses spread attack traffic across many locations. This absorbs the attack before it can overwhelm your application.
Automatic filtering: AWS Shield identifies and mitigates standard DDoS threats automatically. It learns what normal traffic looks like and filters out the bad stuff.

This built-in protection strengthens your security and can save you money on other security tools.

Maintaining client connection consistency

For some applications, like a shopping cart, you need a user to stay connected to the same server. AWS Global Accelerator handles this with a feature called client affinity.

Client affinity, or “session stickiness,” makes sure user’s requests always go to the same endpoint. This is vital for stateful applications where context matters. It keeps the user experience smooth, even if you are adding or removing servers in the background.

Global traffic distribution with fault isolation

AWS Global Accelerator intelligently isolates problems. If one endpoint or even an entire region has an issue, it is automatically isolated. Traffic is then spread across your remaining healthy resources.

You can manually control traffic distribution using traffic dials. Say you have planned maintenance in your European data center. You can simply dial down the traffic there and send your European users to your servers in North America. This gives you another layer of control and resilience.

Easy integration with existing infrastructure

One of the best things about AWS Global Accelerator is how easily it fits into your setup. It works with many AWS services and even with your own on-premise servers.

It supports endpoints like:

Application Load Balancers (ALBs)
Network Load Balancers (NLBs)
EC2 Instances
Elastic IP Addresses

This means you can add it to your existing applications without a major redesign. The setup process is simple. You just tell it where your applications live. This makes it a great tool for modernizing older apps or for businesses that use a mix of cloud and on-premise hardware.

Practical applications of AWS Global Accelerator

The theory is great, but where does AWS Global Accelerator make a real difference? It is a perfect fit for any situation where speed, uptime, and a great global user experience matter.

Here are some common uses:

FAQ

Is AWS Global Accelerator the same as Amazon CloudFront?

No, they are different tools for different jobs, but they work well together.

Amazon CloudFront is a Content Delivery Network (CDN). It stores copies of your files (images, videos) in locations around the world. This is called caching. It delivers content faster because the files are closer to the user. It works with web traffic (HTTP/HTTPS).
AWS Global Accelerator does not cache files. It is a network service. Its job is to find the fastest and most reliable path for all kinds of application traffic (TCP and UDP) to travel over the AWS network.

Think of it this way: CloudFront is like having small warehouses for your goods all over the world. Amazon Global Accelerator is the private superhighway that your delivery trucks use to get to the main factory.

Does AWS Global Accelerator support client IP preservation?

Yes, it does. When it sends traffic to your application, it makes sure to include the original user’s IP address. This is very important. Your application might need that IP for security, for analytics, or to show content based on the user’s location.

Can I use AWS Global Accelerator with on-premise applications?

Yes. You can use AWS Accelerator even if your applications are running in your own data center. This lets your on-premise apps get the performance and reliability benefits of the AWS global network.

To do this, you create a secure connection from your data center to AWS. Then, you set up a resource in AWS to act as the endpoint for the accelerator. This resource forwards the traffic to your on-premise servers. This setup gives your users a better, faster connection, even if your app isn’t fully in the cloud.
