Mixing up cloud services for better results

  • Organizations trust the cloud, using it for more critical functions and sensitive data.

  • As private and public clouds are mixed, IT is creating a hybrid WAN to serve the rich service delivery environment.

More enterprises are turning to the cloud for centralized data storage and online access to computer services and resources, whether it’s public, private, or a hybrid. About 97 percent use Software as a Service (SaaS), but very soon more than half will be using public Infrastructure as a Service (IaaS), and more than 40 percent will be using Platform as a Service (PaaS).

More enterprises are using the cloud

As the cloud continues to provide more critical functions and sensitive data, enterprises are trusting and using it more. In practice, enterprises (and, really, midsize and even small organizations) are freely mixing external public and private clouds with existing hosted and managed services, colocated resources, and in-house data centers. In the process, they are creating a rich hybrid service delivery environment, a service-oriented architecture composed of myriad interdependent parts spread across many kinds of infrastructure. 

The evolving Wide Area Network (WAN)

The cloud is changing WANs in two important ways: how distributed networks are managed and how they are delivered. By providing communications between users and service, and among data centers and internal and external resources of all kinds, the evolving WAN supports hybrid service delivery, serving a more agile branching strategy for its users. 

How is this beneficial? The new WAN uses cheaper Internet bandwidth to supplement more expensive dedicated links, and the reliability of dedicated connections to backstop Internet links. Strategies such as Internet-VLAN-as-WAN, Internet-VLAN-supplements-WAN, and distributed Internet access (branch-to-Internet traffic going directly to the Internet, and not first passing through a data center,) are proving instrumental to bringing branch network costs and provisioning times down, as well as potentially improving application performance for all users.
