Using cloud services with your VPN

  • The WAN is the highway that connects users to cloud resources.

  • Using a WAN link to connect corporate sites to cloud services provides a more optimal experience than using the public Internet.

  • The Internet can be prone to slowdowns when traffic levels are high or large applications are running, because it treats all traffic equally.

Today’s cloud services have everyone literally on the move. Cloud services offer users the flexibility to access the data and tools they need to be productive, no matter where they may be located. If your organization is like most companies, flexible work options have become more common in recent years, coinciding with the proliferation of cloud services. And because your users are able to access cloud services over lengthy geographic distances, you likely want an intelligent, managed WAN service supporting the cloud connections.

Having a well-oiled WAN link between users and cloud is a tremendous help to getting the most from your cloud investments. This means a service like your MPLS VPN, which applies class-of-service and bandwidth management to all packet flows to keep each application performing optimally in the context of all network traffic.

As your organization’s use of cloud services picks up, you can utilize your existing MPLS VPN. Cloud-based applications need to perform comparably to a LAN to deliver the response times users expect. But when using cloud resources, you’re dependent on the WAN – the highway connecting users and resources – for top-performing experiences. If left unmanaged, that WAN can introduce distance-related latency and packet retransmissions that might slow down response times.

Sure, you can use the public Internet to connect your corporate sites to the cloud service. And if you layer IPsec encryption on top of it, you gain additional security from a network standpoint. But because Internet links are unmanaged, you’ll be using a best-effort network that treats all traffic equally in a first come, first served manner. This makes the Internet prone to performance slowdowns when traffic levels are high or when “big” applications are running, such as video or high-performance computing.

Users say they don’t care where the resources reside, as long as the resources are readily available and functioning properly. If users don’t get the same experience remotely as they would when locally connected, they won’t use the remote services. So consider your plans to optimize your WAN as an integral component of your cloud strategy.
