If you distribute content at significant scale, you probably count on a content delivery network (CDN) service provider to ensure that your content is always available.
But what happens when you need to do the reverse—to remove your content from a user's access path, just as fast as you delivered it? What happens when hundreds of copies of your file are cached across multiple geo locations, and you need to purge them all immediately?
Consider these scenarios:
(1) An e-commerce company mistakenly posts the wrong image for a low-cost item in its online inventory, displaying the image of a $1,200 product with a $90 price tag.
(2) A global software company discovers a glitch during beta testing, which could cause security issues and provoke customer anger and mistrust. The testing team must react quickly to prevent users from downloading the incorrect version.
(3) The top article on a popular news site contains a reporting error, causing readers to act on false information about a major economic issue and potentially affecting the stock market.
These are extreme examples, but surprisingly common. Consider Amazon's mistaken $0.01 sale of the $599 LG G4 smartphone, the case of the missing Apple Music files, and the New York Times' premature publication of two conflicting articles about a U.S. Senate vote.
CDNs receive regular requests from customers that need to purge content from cache right now. Although their situations are urgent, customers are often left tapping their fingers while content is manually deleted from a centralized queue. Requests can become backlogged and purges can take hours to execute.
A less dramatic example is an organization that regularly replaces or deletes files like scripts and style sheets. In these cases, the consequences of serving stale content may not be as dire. However, purging can still cost your business in the form of process inefficiency.
Even with self-service options, submitting a single command can require a clunky, multi-step workflow that is not repeatable. And verifying that content was actually purged, especially from multiple servers, is a resource drain that consumes valuable cycles and leaves you guessing.
The Internet is a globally interconnected superhighway, where information moves fast and business have to move even faster. SmartPurge from Limelight allows you to shortcut the problems normally associated with purge, deleting content permanently from the network edge in a matter of seconds and removing guesswork from the process.
