FEATURE: SD-WAN
And yet, with all the changes to applications themselves, the typical WAN architecture has seen limited improvements. It’ s an architecture that was optimised for a simpler time, when apps and traffic were delivered out of centralised corporate data centers and over privately managed WANs. This mismatch between apps and networks is causing several undesirable outcomes, including suboptimal application performance, high network costs, difficulty managing or scaling the network, and increased risk in deploying new applications and services.
In short, traditional WAN architectures are facing increasing limitations.
Rise of the hybrid enterprise After years of dipping their toes into the cloud computing waters, 2017 looks to be the year we see enterprises fully embrace the cloud. Eighty-four percent of businesses report their use of the cloud has increased in 2015, and they expect that trend will continue. Half say they will use cloud for at least 75 % of their workloads by 2018.
Yet, they’ re not planning to move all apps to the cloud. Some will continue to live on-premises, particularly those that enable access to sensitive or confidential information, or those that need to run locally at remote locations to support the needs of their business. Companies therefore find themselves with one foot on-premises and one in the cloud. This combination of private and public assets delivering essential business services is known as the“ hybrid enterprise,” and it is the new normal.
IT teams cannot simply provision cloud apps and move on. They need to establish visibility, optimization and control across hybrid clouds and networks to ensure that all onpremises, cloud, and SaaS applications
