Q. What is Amazon CloudFront?
Amazon CloudFront is a web service that gives businesses and web application developers an easy and cost effective way to distribute content with low latency and high data transfer speeds. Like other AWS services, Amazon CloudFront is a self-service, pay-per-use offering, requiring no long term commitments or minimum fees. With CloudFront, your files are delivered to end-users using a global network of edge locations.
Q. What can I do with Amazon CloudFront?
Amazon CloudFront provides a simple API that lets you:
- Distribute content with low latency and high data transfer rates by serving requests using a network of edge locations around the world.
- Get started without negotiating contracts and minimum commitments.
Q. How do I get started with Amazon CloudFront?
Click the “Create Free Account” button on the Amazon CloudFront detail page. If you choose to use another Amazon Web Service as the origin for the files served through Amazon CloudFront, you must sign up for that service before creating CloudFront distributions.
Q. How do I use Amazon CloudFront?
To use Amazon CloudFront, you:
- For static files, store the definitive versions of your files in one or more origin servers. These could be Amazon S3 buckets. For your dynamically generated content that is personalized or customized, you can use Amazon EC2 – or any other web server – as the origin server. These origin servers will store or generate your content that will be distributed through Amazon CloudFront.
- Register your origin servers with Amazon CloudFront through a simple API call. This call will return a CloudFront.net domain name that you can use to distribute content from your origin servers via the Amazon CloudFront service. For instance, you can register the Amazon S3 bucket “bucketname.s3.amazonaws.com” as the origin for all your static content and an Amazon EC2 instance “dynamic.myoriginserver.com” for all your dynamic content. Then, using the API or the AWS Management Console, you can create an Amazon CloudFront distribution that might return “abc123.cloudfront.net” as the distribution domain name.
- Include the cloudfront.net domain name, or a CNAME alias that you create, in your web application, media player, or website. Each request made using the cloudfront.net domain name (or the CNAME you set-up) is routed to the edge location best suited to deliver the content with the highest performance. The edge location will attempt to serve the request with a local copy of the file. If a local copy is not available, Amazon CloudFront will get a copy from the origin. This copy is then available at that edge location for future requests.
Q. How does Amazon CloudFront provide higher performance?
Amazon CloudFront employs a network of edge locations that cache copies of popular files close to your viewers. Amazon CloudFront ensures that end-user requests are served by the closest edge location. As a result, requests travel shorter distances to request objects, improving performance. For files not cached at the edge locations, Amazon CloudFront keeps persistent connections with your origin servers so that those files can be fetched from the origin servers as quickly as possible. Finally, Amazon CloudFront uses additional optimizations – e.g. wider TCP initial congestion window – to provide higher performance while delivering your content to viewers.
Q. How does Amazon CloudFront lower my costs to distribute content over the Internet?
Like other AWS services, Amazon CloudFront has no minimum commitments and charges you only for what you use. Compared to self-hosting, Amazon CloudFront spares you from the expense and complexity of operating a network of cache servers in multiple sites across the internet and eliminates the need to over-provision capacity in order to serve potential spikes in traffic. Amazon CloudFront also uses techniques such as collapsing simultaneous viewer requests at an edge location for the same file into a single request to your origin server. This reduces the load on your origin servers reducing the need to scale your origin infrastructure, which can bring you further cost savings.
Additionally, if you are using an AWS origin (e.g., Amazon S3, Amazon EC2, etc.), effective December 1, 2014, we are no longer charging for AWS data transfer out to Amazon CloudFront. This applies to data transfer from all AWS regions to all global CloudFront edge locations.
Q. How is Amazon CloudFront different from Amazon S3?
Amazon CloudFront is a good choice for distribution of frequently accessed static content that benefits from edge delivery—like popular website images, videos, media files or software downloads.
Q. How is Amazon CloudFront different from traditional content delivery solutions?
Amazon CloudFront lets you quickly obtain the benefits of high performance content delivery without negotiated contracts or high prices. Amazon CloudFront gives all developers access to inexpensive, pay-as-you-go pricing – with a self-service model. Developers also benefit from tight integration with other Amazon Web Services. The solution is simple to use with Amazon S3, Amazon EC2, and Elastic Load Balancing as origin servers, giving developers a powerful combination of durable storage and high performance delivery. Amazon CloudFront also integrates with Amazon Route 53 and AWS CloudFormation for further performance benefits and ease of configuration.
Q. How will I be charged for my use of Amazon CloudFront?
Amazon CloudFront charges are based on actual usage of the service in four areas: Data Transfer Out, HTTP/HTTPS Requests, Invalidation Requests, and Dedicated IP Custom SSL certificates associated with a CloudFront distribution.
With the AWS Free Usage Tier, you can get started with Amazon CloudFront for free. Upon sign-up, new AWS customers receive 50 GB Data Transfer Out and 2,000,000 HTTP and HTTPS Requests for Amazon CloudFront each month for one year.
- Data Transfer Out to Internet
You will be charged for the volume of data transferred out of the Amazon CloudFront edge locations, measured in GB. If you are using other Amazon Web Services as the origins of your files, you will be charged separately for use of those services, including for storage, compute hours, GET requests and data transfer out of that service to Amazon CloudFront’s edge locations. Usage tiers for data transfer are measured separately for each geographic region. You can see the rates for Amazon CloudFront data transfer to the Internet here.
- Data Transfer Out to Origin
You will be charged for the volume of data transferred out, measured in GB, from the Amazon CloudFront edge locations to your origin (both AWS origins and other origin servers). You can see the rates for Amazon CloudFront data transfer to Origin here.
- HTTP/HTTPS Requests
You will be charged for number of HTTP/HTTPS requests made to Amazon CloudFront for your content. You can see the rates for HTTP/HTTPS requests here.
- Invalidation Requests
You are charged per path in your invalidation request. A path listed in your invalidation request represents the URL (or multiple URLs if the path contains a wildcard character) of the object you want to invalidate from CloudFront cache. You can request up to 1,000 paths each month from Amazon CloudFront at no additional charge. Beyond the first 1,000 paths, you will be charged per path listed in your invalidation requests. You can see the rates for invalidation requests here.
- Dedicated IP Custom SSL
You pay $600 per month for each custom SSL certificate associated with one or more CloudFront distributions using the Dedicated IP version of custom SSL certificate support. This monthly fee is pro-rated by the hour. For example, if you had your custom SSL certificate associated with at least one CloudFront distribution for just 24 hours (i.e. 1 day) in the month of June, your total charge for using the custom SSL certificate feature in June will be (1 day / 30 days) * $600 = $20. To use Dedicated IP Custom SSL certificate support, upload a SSL certificate and use the AWS Management Console to associate it with your CloudFront distributions. If you need to associate more than one custom SSL certificate with your CloudFront distribution, please include details about your use case and the number of custom SSL certificates you intend to use in the CloudFront Limit Increase Form.
Usage tiers for data transfer are measured separately for each geographic region. The prices above are exclusive of applicable taxes, fees, or similar governmental charges, if any exist, except as otherwise noted.
Q: Does your prices include taxes?
Except as otherwise noted, our prices are exclusive of applicable taxes and duties, including VAT and applicable sales tax. For customers with a Japanese billing address, use of the Asia Pacific (Tokyo) Region is subject to Japanese Consumption Tax. Learn more.
Q: How am I charged for 304 responses?
A 304 is a response to a conditional GET request and will result in a charge for the HTTP/HTTPS request and the Data Transfer Out to Internet. A 304 response does not contain a message-body; however, the HTTP headers will consume some bandwidth for which you would be charged standard CloudFront data transfer fees. The amount of data transfer depends on the headers associated with your object.
Q. Can I choose to only serve content from less expensive Amazon CloudFront regions?
Yes, "Price Classes" provides you an option to lower the prices you pay to deliver content out of Amazon CloudFront. By default, Amazon CloudFront minimizes end user latency by delivering content from its entire global network of edge locations. However, because we charge more where our costs are higher, this means that you pay more to deliver your content with low latency to end-users in some locations. Price Classes let you reduce your delivery prices by excluding Amazon CloudFront’s more expensive edge locations from your Amazon CloudFront distribution. In these cases, Amazon CloudFront will deliver your content from edge locations within the locations in the price class you selected and charge you the data transfer and request pricing from the actual location where the content was delivered.
If performance is most important to you, you don’t need to do anything; your content will be delivered by our whole network of locations. However, if you wish to use another Price Class, you can configure your distribution through the AWS Management Console or via the Amazon CloudFront API. If you select a price class that does not include all locations, some of your viewers, especially those in geographic locations that are not in your price class, may experience higher latency than if your content were being served from all Amazon CloudFront locations.
Note that Amazon CloudFront may still occasionally serve requests for your content from an edge location in a location that is not included in your price class. When this occurs, you will only be charged the rates for the least expensive location in your price class.
You can see the list of locations making up each price class here.
Q. Can I choose to serve content (or not serve content) to specified countries?
Yes, the Geo Restriction feature lets you specify a list of countries in which your users can access your content. Alternatively, you can specify the countries in which your users cannot access your content. In both cases, CloudFront responds to a request from a viewer in a restricted country with an HTTP status code 403 (Forbidden).
Q. How accurate is your GeoIP database?
The accuracy of the IP Address to country lookup database varies by region. Based on recent tests, our overall accuracy for the IP address to country mapping is 99.8%.
Q. Can I serve a custom error message to my end users?
Yes, you can create custom error messages (for example, an HTML file or a .jpg graphic) with your own branding and content for a variety of HTTP 4xx and 5xx error responses. Then you can configure Amazon CloudFront to return your custom error messages to the viewer when your origin returns one of the specified errors to CloudFront.
Q. Where are the edge locations used by Amazon CloudFront located?
Amazon CloudFront uses a global network of edge locations for content delivery. You can see a full list of Amazon CloudFront locations here.
Q. What types of content does Amazon CloudFront support?
Amazon CloudFront supports all files that can be served over HTTP. This includes dynamic web pages, such as HTML or PHP pages, any popular static files that are a part of your web application, such as website images, audio, video, media files or software downloads. For on-demand media files, you can also choose to stream your content using RTMP delivery. Amazon CloudFront also supports delivery of live media over HTTP.
Q. Does Amazon CloudFront support delivery of dynamic content?
Amazon CloudFront supports all files that can be served over HTTP. This includes dynamic web pages, such as HTML or PHP pages, any popular static files that are a part of your web application, such as website images, audio streams, video streams, media files or software downloads. For on-demand media files, you can also choose to stream your content using RTMP delivery. Amazon CloudFront also supports delivery of live media over HTTP.
Q. Is Amazon CloudFront PCI compliant?
Yes, Amazon CloudFront is included in the set of services that are compliant with the Payment Card Industry Data Security Standard (PCI DSS) Merchant Level 1, the highest level of compliance for service providers. Please see our developer's guide for more information.
Q. How does Amazon CloudFront speed up my entire website?
Amazon CloudFront uses standard cache control headers you set on your files to identify static and dynamic content. Delivering all your content using a single Amazon CloudFront distribution helps you make sure that performance optimizations are applied to your entire website or web application. When using AWS origins, you benefit from improved performance, reliability, and ease of use as a result of AWS’s ability to track and adjust origin routes, monitor system health, respond quickly when any issues occur, and the integration of Amazon CloudFront with other AWS services. You also benefit from using different origins for different types of content on a single site – e.g. Amazon S3 for static objects, Amazon EC2 for dynamic content, and custom origins for third-party content – paying only for what you use.
Q. Does Amazon CloudFront work with non-AWS origin servers?
Yes. Amazon CloudFront works with any origin server that holds the original, definitive versions of your content, both static and dynamic. There is no additional charge to use a custom origin.
Q. What types of HTTP requests are supported by Amazon CloudFront?
Amazon CloudFront currently supports GET, HEAD, POST, PUT, PATCH, DELETE and OPTIONS requests.
Q. Does Amazon CloudFront cache POST responses?
Amazon CloudFront does not cache the responses to POST, PUT, DELETE, and PATCH requests – these requests are proxied back to the origin server. You may enable caching for the responses to OPTIONS requests.
Q. Does Amazon CloudFront support access controls for paid or private content?
Yes, Amazon CloudFront has an optional private content feature. When this option is enabled, Amazon CloudFront will only deliver files when you say it is okay to do so by securely signing your requests. Learn more about this feature by reading the CloudFront Developer Guide.
Q. How can I protect my web applications delivered via CloudFront?
You can integrate your CloudFront distribution with AWS WAF, a web application firewall that helps protect web applications from attacks by allowing you to configure rules based on IP addresses, HTTP headers, and custom URI strings. Using these rules, AWS WAF can block, allow, or monitor (count) web requests for your web application. Please see AWS WAF Developer Guide for more information.
Q. Does Amazon CloudFront support CNAMEs?
Yes. You can add up to ten CNAME aliases to each of your distributions. Amazon CloudFront also supports wildcard CNAMEs.
Q. Can I use a CNAME alias I create for my CloudFront distribution to deliver content over HTTPS?
Yes. You can use either the Dedicated IP Custom SSL or SNI Custom SSL feature to deliver content over HTTPS using your own domain name and your own SSL certificate. This gives visitors to your website the security benefits of CloudFront over an SSL connection that uses your own domain name in addition to lower latency and higher reliability. Learn more about the Custom SSL features by visiting the CloudFront Custom SSL detail page and see how to set your CloudFront HTTPS settings by reading the CloudFront Developer Guide.
Q. What is the difference between SNI Custom SSL and Dedicated IP Custom SSL of Amazon CloudFront?
Dedicated IP Custom SSL allocates dedicated IP addresses to serve your SSL content at each CloudFront edge location. Because there is a one to one mapping between IP addresses and SSL certificates, Dedicated IP Custom SSL works with browsers and other clients that do not support SNI. Due to the current IP address costs, Dedicated IP Custom SSL is $600/month prorated by the hour.
SNI Custom SSL relies on the SNI extension of the Transport Layer Security protocol, which allows multiple domains to serve SSL traffic over the same IP address by including the hostname viewers are trying to connect to. As with Dedicated IP Custom SSL, CloudFront delivers content from each Amazon CloudFront edge location and with the same security as the Dedicated IP Custom SSL feature. SNI Custom SSL works with most modern browsers, including Chrome version 6 and later (running on Windows XP and later or OS X 10.5.7 and later), Safari version 3 and later (running on Windows Vista and later or Mac OS X 10.5.6. and later), Firefox 2.0 and later, and Internet Explorer 7 and later (running on Windows Vista and later). Older browsers that do not support SNI cannot establish a connection with CloudFront to load the HTTPS version of your content. SNI Custom SSL is available at no additional cost beyond standard CloudFront data transfer and request fees.
Q. What is Server Name Indication?
Server Name Indication (SNI) is an extension of the Transport Layer Security (TLS) protocol. This mechanism identifies the domain (server name) of the associated SSL request so the proper certificate can be used in the SSL handshake. This allows a single IP address to be used across multiple servers. SNI requires browser support to add the server name, and while most modern browsers support it, there are a few legacy browsers that do not. For more details see the SNI section of the CloudFront Developer Guide or the SNI Wikipedia article.
Q. Can I point my zone apex (example.com versus www.example.com) at my Amazon CloudFront distribution?
Yes. By using Amazon Route 53, AWS’s authoritative DNS service, you can configure an ‘Alias’ record that lets you map the apex or root (example.com) of your DNS name to your Amazon CloudFront distribution. Amazon Route 53 will then respond to each request for an Alias record with the right IP address(es) for your CloudFront distribution. Route 53 doesn't charge for queries to Alias records that are mapped to a CloudFront distribution. These queries are listed as "Intra-AWS-DNS-Queries" on the Amazon Route 53 usage report.
Q. How does Amazon CloudFront handle query string parameters in the URL?
A query string may be optionally configured to be part of the cache key for identifying objects in the Amazon CloudFront cache. This helps you build dynamic web pages (e.g. search results) that may be cached at the edge for some amount of time.
Q. How does Amazon CloudFront handle HTTP cookies?
Amazon CloudFront supports delivery of dynamic content that is customized or personalized using HTTP cookies. To use this feature, you specify whether you want Amazon CloudFront to forward some or all of your cookies to your custom origin server. Amazon CloudFront then considers the forwarded cookie values when identifying a unique object in its cache. This way, your end users get both the benefit of content that is personalized just for them with a cookie and the performance benefits of Amazon CloudFront. You can also optionally choose to log the cookie values in Amazon CloudFront access logs.
Q. How long will Amazon CloudFront keep my files at the edge locations?
By default, if no cache control header is set, each edge location checks for an updated version of your file whenever it receives a request more than 24 hours after the previous time it checked the origin for changes to that file. This is called the “expiration period.” You can set this expiration period as short as 0 seconds, or as long as you’d like, by setting the cache control headers on your files in your origin. Amazon CloudFront uses these cache control headers to determine how frequently it needs to check the origin for an updated version of that file. For expiration period set to 0 seconds, Amazon CloudFront will revalidate every request with the origin server. If your files don’t change very often, it is best practice to set a long expiration period and implement a versioning system to manage updates to your files.
Q. How do I remove an item from Amazon CloudFront edge locations?
There are multiple options for removing a file from the edge locations. You can simply delete the file from your origin and as content in the edge locations reaches the expiration period defined in each object’s HTTP header, it will be removed. In the event that offensive or potentially harmful material needs to be removed before the specified expiration time, you can use the Invalidation API to remove the object from all Amazon CloudFront edge locations. You can see the charge for making invalidation requests here.
Q. Is there a limit to the number of invalidation requests I can make?
If you're invalidating objects individually, you can have invalidation requests for up to 3,000 objects per distribution in progress at one time. This can be one invalidation request for up to 3,000 objects, up to 3,000 requests for one object each, or any other combination that doesn't exceed 3,000 objects.
If you're using the * wildcard, you can have requests for up to 15 invalidation paths in progress at one time. You can also have invalidation requests for up to 3,000 individual objects per distribution in progress at the same time; the limit on wildcard invalidation requests is independent of the limit on invalidating objects individually. If you exceed this limit, further invalidation requests will receive an error response until one of the earlier request completes.
You should use invalidation only in unexpected circumstances; if you know beforehand that your files will need to be removed from cache frequently, it is recommended that you either implement a versioning system for your files and/or set a short expiration period.
Q. What is streaming? Why would I want to stream my content?
Generally, streaming refers to delivering audio and video to end users on the internet without having to download the media file prior to playback. The protocols used for streaming include proprietary ones such as Adobe’s Real Time Messaging Protocol (RTMP) and those that use HTTP for delivery such as Apple’s HTTP Live Streaming (HLS), Adobe’s HTTP Dynamic Streaming (HDS) and Microsoft’s Smooth Streaming. These protocols are different than the delivery of web pages and other content because streaming protocols deliver content in real time – the viewers watch the bytes as they are delivered. Streaming content has several potential benefits for you and your end-users:
- Streaming can give viewers more control over their viewing experience. For instance, it is easier for a viewer to seek forward in a video using streaming than using traditional download delivery.
- Streaming can give you more control over your content, as no file remains on the viewer's computer when they finish watching a video.
- Streaming can help you reduce your costs, as it only delivers portions of a media file that the viewers actually watch. In contrast, with traditional downloads, frequently the whole media file will be downloaded by the viewers, even if they only watch a portion of the file.
Q. Does Amazon CloudFront support on-demand streaming protocols?
Yes, Amazon CloudFront provides you with multiple options to deliver on-demand content. If you have media files that have been converted to either HLS format or Microsoft Smooth Streaming format prior to storing in Amazon S3 (or a custom origin), you can use an Amazon CloudFront web distribution to stream in that format without having to run any media servers. In addition you can also run a third party streaming server (e.g. Wowza Media Server available on AWS Marketplace) on Amazon EC2 which can convert a media file to the required HTTP streaming format. This server can then be designated as the origin for an Amazon CloudFront web distribution. Another option, if you want to stream using RTMP, is to store your media files on Amazon S3 and use it as the origin for an Amazon CloudFront RTMP distribution.
Q. Does Amazon CloudFront support live streaming to multiple platforms?
Yes. Amazon CloudFront provides you three options to easily and cost-effectively deliver live events over HTTP to multiple platforms:
- Live Streaming using Wowza Media Server 3.6: Using Amazon CloudFront with Wowza Media Server combines the benefits of Wowza Media Server with the reliability, scalability, low latency and cost-efficiency of Amazon CloudFront to stream live events to multiple streaming formats, including Apple HTTP Live Streaming (HLS), Adobe HTTP Dynamic Streaming (HDS) and Microsoft Smooth Streaming. We've made this simple for you by creating an AWS CloudFormation template that handles all of the provisioning and sequencing for all the AWS resources you need for this live streaming stack. Amazon CloudFront provides you the scale and flexible pay-as-you-go pricing model, while the use of HTTP protocols for streaming your live event offers your viewers easy access to your live content. Using Amazon CloudFront for live streaming also gives you full control of your Wowza origin server so you can configure it to best work with the specific nature of your event. In addition, you can choose the Amazon EC2 instance type and AWS region that best meet the needs of your live event. A detailed tutorial for setting-up live HTTP streaming using Amazon CloudFront is available here.
- Live Streaming using Adobe Media Server 5.0: Amazon CloudFront can be used with Amazon EC2 running Adobe Media Server (AMS 5.0) for live HTTP streaming to both Flash Player and Apple iOS devices. Amazon EC2 (running AMS 5.0) must be configured as the origin for a CloudFront web distribution. Similar to our other live streaming solutions we have setup an AWS CloudFormation template to make it easy for you to setup your pay-as-you-go streaming stack while providing you with full control of the AMS server running in the Amazon EC2 instances provisioned. A detailed tutorial (which also points to the AWS CloudFormation templates) for setting-up live HTTP streaming using CloudFront and AMS 5.0 is available here.
- Live Streaming using Windows Media Services: You can also use Amazon CloudFront and Amazon EC2 running Windows Media Services for live streaming. With this solution, you can deliver live media over HTTP to both Microsoft Silverlight clients and Apple iOS devices. We've made it simple to get started by creating a tutorial and an AWS CloudFormation template to automate the provisioning of AWS resources for your live streaming stack. You only pay for the AWS resources you consume, and have full control over the origin server (Amazon EC2 instance running Windows Media Services) so you can configure additional IIS Live Smooth Streaming functionality.
Q. Does Amazon CloudFront support content coding?
Yes. Amazon CloudFront supports content coding. For more information about how to take advantage of this feature, please see the Developer’s Guide.

Q: What tools and libraries work with Amazon CloudFront?
There are a variety of tools for managing your Amazon CloudFront distribution and libraries for various programming languages available in our resource center.
Q: Can I get access to request logs for content delivered through Amazon CloudFront?
Yes. When you create or modify a CloudFront distribution, you can enable access logging. When enabled, this feature will automatically write detailed log information in a W3C extended format into an Amazon S3 bucket that you specify. Access logs contain detailed information about each request for your content, including the object requested, the date and time of the request, the edge location serving the request, the client IP address, the referrer, the user agent, the cookie header, and the result type (for example, cache hit/miss/error).
Q: Does Amazon CloudFront offer ready-to-use reports so I can learn more about my usage, viewers, and content being served?
Yes. Whether it's receiving detailed cache statistics reports, monitoring your CloudFront usage, seeing where your customers are viewing your content from, or setting near real-time alarms on operational metrics, Amazon CloudFront offers a variety of solutions for your reporting needs. You can access all our reporting options by visiting the Amazon CloudFront Reporting & Analytics dashboard in the AWS Management Console. You can also learn more about our various reporting options by viewing Amazon CloudFront's Reports & Analytics page.
Q: Can I get a history of all Amazon CloudFront API calls made on my account for security, operational or compliance auditing?
Yes. To receive a history of all Amazon CloudFront API calls made on your account, you simply turn on AWS CloudTrail in the CloudTrail's AWS Management Console. For more information, visit AWS CloudTrail home page.
Q: Do you have options for monitoring and alarming metrics in real time?
You can monitor, alarm and receive notifications on the operational performance of your Amazon CloudFront distributions within just a few minutes of the viewer request using Amazon CloudWatch. CloudFront automatically publishes six operational metrics, each at 1-minute granularity, into Amazon CloudWatch. You can then use CloudWatch to set alarms on any abnormal patterns in your CloudFront traffic. To learn how to get started monitoring CloudFront activity and setting alarms via CloudWatch, please view our walkthrough in the Amazon CloudFront Developer Guide or simply navigate to the Amazon CloudFront Management Console and select Monitoring & Alarming in the navigation pane.
Q: Can I use the AWS Management Console with Amazon CloudFront?
Yes. You can use the AWS Management Console to configure and manage Amazon CloudFront though a simple, point-and-click web interface. The AWS Management Console supports most of Amazon CloudFront’s features, letting you get Amazon CloudFront’s low latency delivery without writing any code or installing any software. Access to the AWS Management Console is provided free of charge at https://console.aws.amazon.com
Q: Does Amazon CloudFront offer a Service Level Agreement (SLA)?
Yes. The Amazon CloudFront SLA provides for a service credit if a customer’s monthly uptime percentage is below our service commitment in any billing cycle. More information can be found here
