What are the options for Content Distribution Networks for use with WordPress? I’d like to their objective pros and cons, their associated plugins or other ways to utilize them, their relative pricing, their appropriate customer profiles/scenarios/use-cases, projects they’ve been used on if you know of any, and any other relevant information.
This is a community wiki and so please provide only one CDN option per answer and please don’t duplicate answers. If you have something to include regarding a CDN already listed please either edit the answer or add comments. And please vote up the solutions you recommend and/or think are most viable.
UPDATE: I found few resources on the web for WordPress+CDN so decided to list them here too:
Amazon CloudFront
Amazon CloudFront is an CDN ‘wrapper’ around Amazon’s S3 service. Distributions can be created from existing S3 buckets, and when a file is requested from it’s CloudFront URL it is either served from the nearest edge locations’s cache or fetched from S3 and cached.
Plugins
Pros
Cons
Use Cases
Amazon lists a few use cases on their CloudFront product page, including hosting frequently accessed content, distributing software, and publishing media files.
In terms of businesses using CloudFront as their CDN, Linden Lab (the makers of Second Life) use CF for distributing their software client, while storing other files on S3. Amazon also has a very good case study on how photoWALL uses CF (and the other infrastructure AWS offers)
Rackspace Cloud Files
You can sign up for Rackspace Cloud files, and pay only what you use, this can be a good way to start out, as you don’t need to pay upfront for a large amount of bandwidth, that you may or may not use.
There are two plugins that work well with WordPress and Cloud Files,
Cloud Tools plugin. This is a plugin
by Paul Kehrer, it’ll upload images
to Rackspace in line with a new
post, and upload images already on
the system to cloud files, and
rewrite all your image tags.
W3 Total Cache: This has more
options in terms of different
CDNs..one of them being Rackspace
Cloud Files.
Pros of Rackspace Cloud Files
Cons
To get an estimate of costs, you can go to:
I’ve used them on some sites, they’re reliable, very fast, and reasonably priced. For some clients that have no idea what level of traffic they’ll get, we start them off here.
MaxCDN and W3 Total Cache
MaxCDN and W3 Total Cache has done a great job for me. Max CDN is now $.10 per GB (see: current pricing). Very Cheap and Fast.
Rack Space is $.22 and requires work.
Max CDN Takes about 10 minutes to set up.
I have done about 20 TB with them since I started using them with only one small issue that they fixed within an hour. All I did was turn off the CDN in my control panel till they fixed it.
