Emergence of "Cloud Computing" has evidently lifted the expectations of the companies by allowing them to constitute their own IT infrastructure. Scaling is no longer a frantic, expensive and time engrossing chore as it proffers ability to do so in real-time, generating plethora of opportunities for SME's, SOHO, and SMB's to compete and prevail. Besides massive computing power at your fingertips, there are a few potential challenges, such as data congestion, and security that demands for prudent analysis. However, these challenges can be effectively met with Content Delivery Networks (CDN). Both the cloud and CDN's are utility based platforms, each designed to serve specific purposes. An apt fortification of Cloud + CDN can give best of both the worlds.

Cloud computing is a network of servers; clubbed together to feed the computing need of multiple users; deployed in a dedicated data center. On the contrary, Content Delivery Network is also a group of servers, however, distributed in different locations to place the content in geographic proximity to the users. The major role of CDN is to fasten-up and optimize the media delivery satisfying online user experience. Additionally, it delivers bulky files and software at no additional costs of building a global network.

The Cloud offer businesses a cogent way to broaden their infrastructure horizon, on demand resource allocation and an ability to scale virtually without asking to invest in expensive hardware components. With an ability to replicate infrastructure in the desired geographic locations by simply having a virtual machine with perquisite configurations, Cloud services prove to be a more cost-effective way to scale and minimize latency for geographically spread zones.

Cloud is a utility computing platform composed of multiple physical stacks of computational resources, influential for handling big data and business computing needs. Contrariwise, a CDN is a utility delivery platform, especially designed to deliver content from servers to the users as a part of a repeatable process.

Indeed, cloud has revitalized the IT infrastructure in terms of cost; the fact that it has also created an elevated demand for CDN's can't be suppressed. The massive computing power available through cloud requires unswerving and smooth content distribution to improvise end-user experience.

At the end, it can be concluded that both, Cloud and CDN's can together create a robust system that can accommodate the demands for both the content delivery as well as for the mesmerizing computing power.
