IaaS, PaaS, SaaS — today’s cloud computing services offer multiple layers of elasticity, so enterprises can focus on their customers’ solutions. One crucial aspect to a successful cloud strategy that is often underestimated is selecting the right Content Delivery Network (CDN).
CDNs should be seen as a strategic investment that can enhance an enterprise’s agility and information systems efficiency beyond the cloud layer — while supporting operations, finance, and budgeting processes.
The three key benefits of a modern CDN are:
1. Global reach and performance
A strong enterprise requires instant access to large data stores. Content needs to be available in a number of different formats depending on the device and network connection. A CDN provides all of this without any internal overhead or capital expense.
By maintaining a global network of concentrated server locations (Super Nodes), a CDN ensures the content is easily available for fast download at all times, worldwide.
2. Flexibility & Self Provisioning
Moving away from investing in expensive hardware storage and network infrastructure, a CDN lets the enterprise provide its services through a cost effective operational expense model. These services are billed in a consumption model eliminating the need for a large upfront hardware and software investment and the associated IT deployments efforts.
CDNs also offer access-control options to restrict availability down to a content-specific level. These advanced content controls are available without an additional software or hardware investment.
There is an emerging trend to allow IT usage to be billed back to individual departments rather than rolled into general corporate overhead. With hierarchical accounts, CDN usage can be billed to specific departments under the master organization as well as providing finer grained access controls to CDN settings.
The master organization benefits from economies of scale via a master service agreement and distributes the costs through internal charge-backs. Because each sub-entity is billed for only their charges, new sub-entities can be brought online in a fiscally controlled manner.
Modern CDNs can be integrated into all cloud service layers while offering the enterprise additional delivery and control capabilities. Choosing the right CDNs helps to decrease network latency and optimize the performance of overall cloud solutions — leading to improved customer and user satisfaction.
