This article provides an overview of Rackspace Cloud Files and its features to help you get started quickly and serve content over Akamai’s content delivery network (CDN) service.
Cloud Files is a cloud storage system rather than a traditional file system. You use it to store data in the Rackspace infrastructure. You can perform most data management tasks from the Cloud Control Panel, but the Cloud Files API Developer Guide and some third-party tools are also available.
Cloud Files has the following characteristics:
For more details, see the Cloud Files Key Concepts.
When you use the Cloud Files service, you automatically get access to the Akamai CDN. The CDN works by distributing the content that you upload to Cloud Files across a global network of edge servers. When someone views content from your site, the CDN-enabled content is served from the edge server that is geographically closet to the viewer’s location.
Using the CDN dramatically increases the speed at which websites can load, no matter where the viewer is located. This can be a great advantage when you are hosting content for an international audience.
When a Cloud Files user marks containers for publishing to the CDN, they are instantly accessible through the Akamai CDN. The propagation of content to the edge locations is done automatically.
In the Cloud Control Panel, you use the CDN by creating a Cloud Files container (the storage compartment for data), uploading objects (the files to serve over CDN) to it, and marking the container as public. The container is then assigned a unique URL that can be combined with object names to embed in web pages, email messages, blog posts, and so on.
For example, a user could upload a photo to a container called images. When this Container is published, it is assigned a unique URL such as https://c0000532.cdn.cloudfiles.rackspace.com. The user could then share a link to the photo, such as https://c0000532.cdn.cloudfiles.rackspace.com/IMG_3432.jpg. When that link is accessed, the photo is served from the CDN.
Use the following steps to create a container and make it public:
You can now share the files within the container.
Use the following steps to upload files to a container:
Click the name of the container to which you want to upload files.
Click Upload Files and select the files to upload.
After the files are uploaded, click Close Window.
The files appear in the list of available files within the container.
Click the gear icon next to a file and select View All Links.
Options for sharing your file are displayed.
