Understanding AWS Shield Costs for Your Business
When you're running applications and services on Amazon Web Services (AWS), security is paramount. One of the key services AWS offers to protect your web applications from Distributed Denial of Service (DDoS) attacks is AWS Shield. But a common question for businesses of all sizes is: How much is AWS Shield? The answer isn't a single dollar amount, as it depends on which version of Shield you choose and your specific AWS usage.
AWS Shield: Two Tiers of Protection
AWS Shield comes in two distinct tiers: AWS Shield Standard and AWS Shield Advanced. Each offers a different level of protection and comes with a different pricing model. Understanding these differences is crucial for making an informed decision about your security budget.
AWS Shield Standard: Free and Always On
For every AWS customer, AWS Shield Standard is included at no additional cost. This means you automatically benefit from its protections without paying anything extra. AWS Shield Standard provides always-on detection and automatic inline mitigations against common, frequently occurring network and transport layer DDoS attacks that aim to take your applications offline.
- What it covers: This includes attacks like SYN floods, UDP reflection attacks, and other common volumetric attacks.
- How it works: AWS Shield Standard integrates seamlessly with other AWS services, such as Amazon CloudFront, Amazon Route 53, and AWS Elastic Load Balancing, to provide broad network availability.
- Cost: Absolutely free. There are no separate charges for AWS Shield Standard.
While Shield Standard is a great baseline, it's designed for general protection against common threats. For more sophisticated or large-scale attacks, or if you require more advanced visibility and support, you'll want to look at AWS Shield Advanced.
AWS Shield Advanced: Enhanced Protection and Support
AWS Shield Advanced is a paid service designed for customers who need more advanced DDoS protection, visibility, and response capabilities. This tier is particularly beneficial for businesses running mission-critical applications where downtime can have significant financial and reputational consequences.
The pricing for AWS Shield Advanced has two components:
- Monthly Fee: You pay a fixed monthly fee for each AWS account that is protected by AWS Shield Advanced.
- Data Transfer Fee: You also pay a fee based on the amount of data transferred out of your AWS resources during an attack. This fee is only charged when an attack occurs, and it's designed to be cost-effective by reducing your potential data egress charges during a DDoS event.
Let's break down these costs:
AWS Shield Advanced Pricing Details
As of our last update, the pricing for AWS Shield Advanced is as follows:
- Monthly Fee: $3,000 per account, per month. This fee covers the advanced protection features and resources for your AWS account.
- Data Transfer Fee (During an Attack): $0.01 per GB of data transferred out of your AWS resources during a DDoS attack. This is a significant benefit, as standard data transfer fees can be much higher. AWS Shield Advanced will automatically provide you with this reduced rate during a detected attack.
Important Note: AWS pricing can change. It's always best to refer to the official AWS Shield pricing page for the most up-to-date information.
What You Get with AWS Shield Advanced
The $3,000 monthly fee for AWS Shield Advanced unlocks a suite of powerful features:
- Enhanced Detection and Mitigation: More sophisticated detection algorithms and automated mitigations for a wider range of DDoS attacks, including application layer (Layer 7) attacks.
- Real-time Visibility: Access to detailed metrics and logs about DDoS attacks affecting your resources. This allows you to understand the nature and scope of an attack.
- DDoS Response Team (DRT) Support: 24/7 access to AWS's expert DDoS Response Team. If a significant attack occurs, the DRT can provide custom mitigation and assist with recovery.
- Cost Protection: As mentioned, the data transfer fee during an attack is capped at $0.01 per GB, significantly reducing your costs compared to standard data egress charges. AWS Shield Advanced also offers credits for usage costs incurred during a DDoS attack.
- Protection for Amazon CloudFront, Route 53, Elastic Load Balancing, and Elastic IP addresses.
Calculating Your Potential AWS Shield Costs
For most businesses, the decision comes down to whether AWS Shield Standard's free protection is sufficient or if the advanced features and support of AWS Shield Advanced are necessary.
Scenario 1: You use AWS Shield Standard only.
Your cost for AWS Shield is $0.
Scenario 2: You use AWS Shield Advanced.
You will incur a monthly fee of $3,000 per protected account, plus any data transfer charges during an attack. AWS offers cost protection credits, meaning if the cost of the data transfer during an attack exceeds the monthly fee, you may receive credits. However, the baseline cost is the $3,000 per month.
Consider the following when deciding:
- Criticality of your applications: Are your applications essential for your business operations?
- Potential impact of downtime: How much revenue or reputation would you lose if your service was unavailable due to a DDoS attack?
- Need for expert support: Do you have the internal expertise to handle complex DDoS attacks, or would you prefer AWS's dedicated support?
- Budget constraints: Can your budget accommodate the $3,000 monthly fee?
Is AWS Shield Advanced Worth the Cost?
For businesses that rely heavily on their online presence and cannot afford significant downtime, AWS Shield Advanced is often considered a worthwhile investment. The peace of mind that comes with expert support and advanced protection, combined with the cost savings during an actual attack, can outweigh the monthly fee.
However, for smaller businesses or those with less critical applications, the robust, free protection offered by AWS Shield Standard might be sufficient. It's important to assess your specific risk profile and business needs.
