Office 365 migration and deployment

You can finally stop backhauling Office traffic to the data center

When Microsoft Exchange servers and Office applications were on-premises, you had to backhaul traffic from remote sites and mobile users to the data center. It was the only way to provide off-network connectivity. But now that these services have moved to the cloud in the form of Office 365, backhauling all of your traffic to your data centers no longer makes sense.



Infrastructure upgrade costs

  • 40% higher network utilization can quickly exceed firewall capacity
  • Additional MPLS bandwidth to backhaul traffic

Increased complexity

  • Microsoft recommends no more than 2,000 users behind each public IP address
  • To prioritize traffic, you need to manage IP address ranges and URL changes

Poor user experience

  • Backhauling traffic from branches introduces latency
  • Microsoft recommends 50ms from the client to the application

Why Office 365?

The adoption of Microsoft Office 365 is increasing faster than any other cloud application (Source: Okta) for several reasons:


When businesses are looking to upgrade or move to Exchange, it can be a strategic and cost-effective decision to move to Office 365 instead. In addition to business-class email, users get the Office suite, Yammer, SharePoint, Skype for Business, and OneDrive for Business (cloud storage). Office 365 offers cost-effective licensing, while providing a wealth of useful applications.


Microsoft Office 365 includes applications users know, such as Outlook, Word, and Excel, as well as new productivity applications. Businesses get the benefits of a cloud offering and high adoption rates without the cost of training for new apps.


The greatest benefit of cloud technology is that users can access all their files and applications anywhere — all they need is an Internet connection. There’s no need for remote logins, VPN connections, or the old-fashioned methods of emailing files home or taking them via removable media. The cloud simplifies access while eliminating many security risks.


As new application versions are released, Office 365 users get immediate access to them — they can benefit from new functionality without ever having to buy or install upgrades. Office 365 also dramatically simplifies the task of managing licenses for organizations with a few hundred or many thousands of users.
