No matter how an enterprise might feel about the cloud, it’s no longer possible to avoid it. Employees demand the flexibility of accessing information and tools no matter where they are working from, as well as the ability to collaborate with colleagues, partners, and customers around the globe. As cloud applications continue to grow in popularity, it will be increasingly difficult for MPLS or public internet to keep up without sacrificing user productivity and satisfaction in the process. That is without a little help from a Software-Defined Wide-Area Network or SD-WAN solution. The SD-WAN is a dynamic hybrid networking approach that can integrate multiple network connections, including MPLS, IPsec, Broadband, and LTE. The solution prepares the WAN for the future by making it more flexible and improving the network’s performance, efficiency, and security at the same time.
From bandwidth to consistency, there are many reasons why an organization should consider SD-WAN to replace or augment their traditional WAN. Let’s review when and why you should consider making the leap to global SD-WAN:
- We rely heavily on cloud services- Believe it or not cloud traffic will represent 95% of total data center traffic by 2021, according to Cisco. For businesses, this traffic encompasses everything from Enterprise Resource Planning (ERP) systems to collaboration, analytics, and Unified Communications platforms. With all of this traffic in the cloud, organizations need the ability to add capacity fast and to make decisions about what services are the most critical. SD-WAN delivers this capability with fast scalability and network-based policy and performance routing features. Organizations can ensure high-bandwidth applications run as they should while routing lower-bandwidth apps to other network connections like broadband. Software-defined network for cloud-based deployments coupled with open architecture hardware is ideal because it allows an organization to complement its core network using broadband connections.
- We have high traffic and data costs- The truth is that data is exploding worldwide, driven by mobile traffic, big data, the Internet of Things (IoT), video, the proliferation of network-attached and wireless devices, and the adoption of cloud delivery models. SD-WAN can help organizations meet traffic demands while saving money and decreasing their reliance on MPLS. Because of SD-WAN businesses can diversify connections and purchase lower-cost broadband as a great way to manage overall WAN traffic, without breaking the bank.
- Our offices are distributed and workers are remote- As organizations add branch offices and support a remote workforce, the traditional enterprise WAN can hold them back from reaching their full potential. Conventionally, IT would rely on MPLS, cable internet, or wireless services for branch deployment leaving employees vulnerable to costly circuit failures and downtime. Not only that branch offices and remote workers also rely on data and applications in the cloud. In a traditional WAN environment, traffic is backhauled and sent back across the Internet to the corporate hub, causing significant latency problems and consuming expensive MPLS bandwidth, especially when the central portal and branch offices are far from each other. SD-WAN is an ideal solution for branch and remote deployments because virtualized data services normalize Internet services, cable, and 4G/LTE, as well as MPLS into a single network for better performance and access to cloud services. Not only that, controllers create traffic policies for virtual and physical appliances at each location. So, business-critical applications are prioritized accordingly.
Whether it’s accessing Office 365, or extending your WAN to AWS and Azure, SD-WAN gives organizations the most direct route for accessing these applications. SD-WAN offers organizations a single framework for all users and applications making IT agile enough to support branch offices and a remote, mobile workforce.
