Many enterprises overlook the impact of Office 365 on their entire network infrastructure. That’s a big mistake. Office 365 is a hosted productivity application, which means large files are regularly moved between desktops and the cloud.
Consider: A medium-duty Exchange 2007/2010/2013 user typically consumes 2600 KB/day. The same Office 365 user will consume 12,500 KB – a 5x increase. But that’s just the tip of the iceberg.
On-premises Exchange routes or “back hauls” all corporate email traffic through a central server or resource. In contrast, Office 365 works better when individual branch locations have their own local Internet breakouts.
As a result, organizations now must also handle the additional challenges of managing a multi-firewall deployment, including rules and lifecycle management, to name just two. The amount of additional Internet traffic generated by Office 365 also increases the importance of management policies that facilitate accessibility to critical applications. Further, administrators must have greater insight into application usage to optimize their network policies.
Not doing so can quickly lead to big problems. “The overall increase in traffic as a result of implementing Office 365 for just half of our users overwhelmed our network gateway,” the IT Director of a large transportation company recently confided. “We ultimately had to run on-premises Exchange because the Internet access just became too slow.”
- Office 365 traffic becomes Internet web traffic
- Additional load on firewall and web security structures
- Organizations must re-architect to provide Internet access at branch offices
- Email impacted by non-critical applications
- Implement scalable, centralized management of multiple firewalls
- Intelligently prioritize network traffic
- Implement link failover and redundancy to ensure availability
- Gain visibility into Office 365 Web
- We are masters of using optimal solutions, tools and services to streamline the process.
