Companies across industries of all sizes require solutions that enable fast, easy deployment and real-time, centralized operations management. SD-WAN is strategically positioned to make the digital transformation a reality. Vinod Kumar Balasubramanyam of VMware spoke at ONUG’s Fall Conference, providing insight into why SD-WAN is the ideal choice for companies of any size. In addition to the benefits of using a scalable cloud architecture, he focused on how VMware SD-WAN by VeloCloud is different from traditional approaches and how it interacts with legacy infrastructures. Here are some highlights from his keynote.
VMware’s Balasubramanyam first addressed why SD-WAN is the logical choice. He noted that if we look at the current state of SD-WAN, most applications are hosted in a data center. With the rise of cloud computing and Software as a Service (SaaS), applications that were formerly hosted in data centers are moving to the cloud. Users must go out to the internet to access their applications. This process introduces a lot of latency because those users are still going through the data center to access their online applications.
For example, popular real-time applications, such as Office365 and Skype, are commonly being used. They are hosted in the cloud, but many companies are still backhauling all this traffic through their data center, an inefficient process that creates a lot of latency.
In addition, this SD-WAN architecture is going to decrease MPLS (Multiprotocol Label Switching) expenses. SD-WAN reduces operational expenses by using the internet to transport traffic. SD-WAN also saves costs by classifying application traffic before sending it off to a particular destination, instead of depending on a Layer 3 destination, as is the case with legacy applications.
SD-WAN extracts the complexity of the “data center set up” to present a simplified process to the end user.
Balasubramanyam emphasized the key capabilities of VMware’s SD-WAN solution. He summed them up in these four bullets.
While the benefits of SD-WAN are extensive, Balasubramanyam boiled them down to these three pillars upon which VMware’s solution is built.
Three main components make up VMware’s SD-WAN Solution. Balasubramanyam broke them down for the audience like this:
VMware offers two available deployments to fit the individual needs of clients, allowing architectural flexibility. One is an enterprise-based deployment and the other is service provider-based. Whether the customer is using the internet or MPLS, VMware is able to aggregate that traffic to a single point of presence, which is the gateway.
Additionally, Balasubramanyam explained that VMware provides top security architecture, including being able to integrate with security provider selections, such as Zscaler and Forcepoint. The solution has a built-in firewall, a firewall VNF and a centralized firewall.
Dynamic Multipath Optimization is a suite of implementations VMware has internally to ensure application performance. This suite is made of up five key parts that work together to guarantee your applications run at peak performance.
Balasubramanyam showed a slide of Dynamic Multipath Optimization in action, demonstrating how it helps guide the best paths, identifying latency, packet loss and jitter.
The key takeaway from Balasubramanyam’s keynote was that SD-WAN is enabling enterprises to reach any kind of cloud, including private, public and hybrid. It’s doing so securely and at scale. The presentation concluded with VMware’s vision for the future and how the company has contributed to ONUG validation testing and advanced load balancing projects.
