Cloud Services and the Impact on MPLS and WAN Technologies
The days of hosting data and applications in a single corporate data center are numbered, if not already long gone. Today, applications and data are often distributed across a variety of locations and/or on the cloud. Not only might you have private, public, partner, and telco data centers along with SaaS and the public Internet involved, you also have end-users accessing all those applications and data from multiple branch offices, home offices, and mobile devices. To further complicate matters, your end-users may be scattered around the globe. Cloud services have changed the enterprise wide area network for good, requiring related technologies such as MPLS and WAN Optimization to evolve (1).
Cloud Computing Strains the WAN
While cloud computing makes it possible to connect to applications and data from virtually any computer or device, the traffic mix and complexity can quickly overwhelm traditional WANs (1). In the no-so-distant past, workers used the Internet to access email and browse the Web. They were not necessarily online non-stop. Today, most of them are. They access applications in the cloud rather than on their hard drives or a local server. They generate and store data in the cloud. They collaborate with one another using cloud-based tools. They talk on the phone using VoIP. They interact with each other, customers, and partners using social media. They hold virtual meetings in the cloud. They watch videos on YouTube. They connect their smartphones and tablets to the WAN as well. It’s no wonder the WAN struggles to keep up.
According to a blog post by Aryaka, a WAN optimization provider, “The end-to-end deployment of a private links to connect offices or a full-mesh deployment across multiple offices allowed for a secure and guaranteed network across geographies and served enterprises well from the 1990s all the way to the early 2010s (2).”
Today, cloud services, telepresence, unified communications, virtualization, IT consolidation, hybrid networks, and the public Internet is the new norm. However, the increased reliance on all the above requires substantial bandwidth improvements. Network bottlenecks can quickly affect productivity. If all of your work is in the cloud, but you can’t access it in an efficient manner, you’re in big trouble.
Overcoming the Shortcomings of MPLS
Though MPLS had a long run and is still used today, MPLS technology is showing its age. Moreover, it is expensive and time consuming to implement, and it struggles when large oceans must be crossed.
The Aryaka blog post suggests the following, “The world of business needs a new network to bring an enterprise together, to allow for improved application performance and data access, to improve communication and collaboration, to bring products to market faster and to increase revenues (2).”
WAN optimization as a service addresses the shortcomings of MPLS, allowing enterprises to tap into Aryaka’s global network for immediate WAN performance. While it can take months to add bandwidth via MPLS upgrades, switching to Aryaka’s WAN Optimization as a Service takes mere minutes. It is a solution built for today’s bandwidth-intensive cloud services.
