How to Solve IT's Underperformance
As organizations move to the cloud, the gap between the needs and expectations of the business and the ability of IT to deliver grows. Companies need a solution that allows networks to be a lot more flexible and agile, and according to Riverbed Technology's Norway Country Manager Trygve Wettestad, it's exactly what they offer.
As organisations migrate to the cloud, and as apps, data, and users being scattered across branch offices and other remote locations, IT is struggling to deliver the performance that businesses need to remain productive.
Why is IT under-performing?
There are two infrastructures that IT is wrestling with today, one is inflexible, and the other, complex:
- The Traditional MPLS WANs or the old-school WANs rely on operation paradigms that were defined more than 15 years ago, at a time were the pace of changes was a matter of months not a matter of days, and could also be expensive.
- The Hybrid WANs are composed of MPLS based networks and one or more Internet links, which could reduce costs. But in many cases, what you save in costs you sacrifice in security and control. Moreover, a significant rise in encryption and cloud technologies can cut into network visibility, making it next to impossible to know when and where a performance problem is occurring.
The Better Choice
Enter SD-WAN (software-defined WAN). This solution allows businesses to control their network from a single, easy-to-use, intuitive command centre. At its core, SD-WAN enables them to make on-the-fly adjustments to network performance and application delivery, in order to meet the businesses ever-changing needs. Here are three more reasons to choose SD-WAN:
- It enables organisations to direct traffic and deploy network services across a WAN from a centralized location — without any mess or hassle, by leveraging software-defined networking (SDN) principles, designed to make networks more flexible and agile.
- It allows network services and policies to be assigned to different locations, users, and even apps — all with just a few clicks, instead of the old router-based model, which required IT managers to make intensive CLI-based code changes to routers.
- An app-centric SD-WAN will automatically identify the applications in the organisation’s network and group them into logical categories based on business criticality, and even apply network-service policies to those categories based on built-in best practices.
These benefits offer IT a broad range of possibilities. Organizations can automatically route voice traffic to their highest-quality network paths. They can quickly segregate employee traffic from that of partners and customers. They can send recreational Internet traffic through the most rigorous firewalls. And more. And IT can do it all simply and centrally, without breaking a sweat.
All in all, SD-WAN makes networks more flexible and agile than ever, which, in turn, allows businesses to meet their needs efficiently and effectively.
