Cloud and mobility have been driving transformative changes in the way we work for nearly a decade and continue to rank among the top macro trends affecting the IT landscape today. In fact, many organizations have begun to build their entire business strategy around cloud capabilities. Enterprise Strategy Group research found that 39% of organizations now follow a "cloud-first" strategy when deploying new applications, up from 29% just a year ago.
By its nature, cloud computing puts distance between users and resources, creating a strain on legacy network capabilities. This is especially true of a traditional hub-and-spoke networking model that incorporates siloed security technologies. This type of approach introduces three key issues:
1. Degradation of performance and user experience: When traffic destined for cloud applications is first routed back to the campus and through the on-premises security stack, quality of service is negatively affected.
2. Limited visibility: Security tools can't control what they can't see, and without a full understanding of applications, users, devices, data, and other context, proper enforcement cannot occur.
3. Inconsistent policies: Appliance sprawl and disparate management consoles have left many organizations with a siloed rather than unified approach to security, which can limit both efficiency and efficacy.
The traditional approach is now changing as network technology becomes more dynamic and intelligently manages traffic based on users, applications, connections, and locations. The growing adoption of SD-WAN to improve network efficiency and management, especially relative to remote office/branch office (ROBO) locations, is a good example of this.
