4 considerations when replacing managed WAN services with SD-WAN

STEVE GARSON | July 9, 2018

The enterprise wide area networks are mission-critical resources for most enterprises. And when it came to managing and running the WAN, enterprises could choose between two distinct models: Do it Yourself (DIY) or managed WAN services. But with the evolution of SD-WANs, we’re seeing a new type of telco solution that merges elements of both capabilities. With DIY, enterprise IT procures last-mile access at a location and deploys routers, WAN optimization, and network security appliances from several vendors. Continuous monitoring and management is done in house or via a managed service provider. In short, enterprise IT owns the complex task of maintaining, configuring and monitoring the WAN for availability and optimal performance.In a managed WAN services model, a telco bundles all of the service components mentioned above and delivers them as a turnkey service. Managed WAN services sound like a great way to offload IT resources, but it comes at a steep price and some difficult tradeoffs. As I’ve pointed out in past blogs, telcos are biased towards the last mile services they offer. And, the complexity of building and running SD-WAN isn’t eliminated, it’s just hidden behind the carrier umbrella. All of which means enterprises end up funding the complexity of the carrier managed services in their monthly bills.

Introducing vSphere 7: Modern Applications & Kubernetes

Article | March 20, 2020

The power of vSphere has always been its ability to support any (x86-based!) application under the sun, running those applications quickly and securely while providing a simplified management environment. Over the past twenty years, across all customers and partners worldwide, over 70 million applications are running on vSphere in total. While new applications run well on vSphere, the real question is how to make vSphere the best place to run those new apps – better than any other infrastructure out there. We believe that with vSphere 7 with Kubernetes, vSphere is now truly the best place for modern applications. Back in VMworld 2019, we announced Project Pacific, a technology preview for how we could integrate Kubernetes with vSphere. It was a profound idea – taking the best of Kubernetes and apply it to vSphere, and the best of vSphere and applying it to Kubernetes. vSphere 7 is the result of this foundational technology work. Unlike many other announcements around vSphere 7, Project Pacific is not a feature of vSphere – it simply is vSphere. vSphere itself has dramatically expanded to include all these great new capabilities.

Getting Above the Silos: The Rise of the Logical Data Fabric

Article | March 20, 2020

With so much valuable data potentially available, it can be frustrating for organizations to discover that they can’t easily work with it because it’s stuck in disconnected silos. Limited data access is a problem when organizations need timely, complete views of all relevant data about customers, supply chains, business performance, public health, and more, to make informed decisions. We need only look at the current COVID-19 pandemic to understand the importance of being able to view and share data across silos. One of the hottest topics in data architecture right now is data fabric. The notion of a data fabric is becoming important as organizations put more data in multiple cloud-based storage platforms, which can add to existing on-premises data silo problems. TDWI research finds that disconnected data silos are one of the biggest obstacles organizations face as they try to enable faster data insights. In the industry, “data fabric” is variously called an architecture, a framework – and of course, a fabric. With data fabric, adherents aim to provide a more universal and holistic approach to integrating diverse components of physically distributed data environments. Ideally, a data fabric will use services to integrate the necessary components so that data flows more easily and users and applications do not have to use specialized code to access each data silo.
