IDG Contributor Network: Communications hubs emerge as a bridge to hybrid IT

Adoption of hybrid IT for delivery of applications across legacy enterprise data centers, and increasingly cloud SaaS and IaaS platforms, is rendering traditional network architectures obsolete. Numerous analysts and articles have predicted the coming obsolescence of hub and spoke MPLS networks anchored on legacy enterprise data centers. While few have detailed what to do about it, a growing number of enterprises are taking matters into their own hands. Those in the know are leveraging communication hubs, sometimes also referred to as cloud hubs, to bridge the gap between their legacy data center environments and the cloud.The growing challenge of SaaS application performance As enterprises accelerate their move to cloud, including the growing trend toward cloud office suites, such as Office 365 and Google Suite, where users expect LAN-like performance, challenges are mounting. According to Microsoft, Office 365 is growing at 43 percent, and as of the end of 2017 was boasting 120 million active users. A 2017 survey by TechValidate noted that despite increasing both firewall and network bandwidth capacity, nearly 70 percent of companies experienced weekly network-related performance issues after deploying Office 365. Gartner’s 2018 Strategic Roadmap for Networking, released earlier this year, noted that nearly all enterprises Continue reading

IDG Contributor Network: To accelerate cloud application performance, start by mapping your apps

In the eternal words of Yogi Berra, “If you don't know where you are going, you'll end up someplace else.” So how does this sage advice apply to the new world of application performance and hybrid IT?As the pace of application migration to the cloud continues to accelerate, enterprise networking teams have turned to hybrid and SD-WANs as practical solutions to open up more localized internet access and direct routing to the cloud. So the theory goes that by deploying broadband and internet connections at the edge of the network, users can bypass the MPLS bottlenecks and avoid transiting the centralized data center internet egress points.So with the proliferation of hybrid and SD-WAN deployments, which according to most analysts is well past the tipping point and going mainstream, why is it that enterprise IT teams are still struggling with cloud application performance? User frustration with the performance of applications like Office 365, Salesforce, Workday, ServiceNow, and others is only growing, rather than waning.To read this article in full, please click here
