Case Studies Lenovo Access to the Workday Application

AppEx CloudWAN optimizes Lenovo’s Cross-‐boarder Workday Application Access
As one of the leading providers of enterprise applications, Workday serves more
than 1,000 organizations, ranging from medium-‐sized businesses to Fortune 50
enterprises. Lenovo is one of these customers accessing the Workday applications
hosted on the East Coast of the United States.
Lenovo users in China needed to access Workday servers located in Washington D.C.
to research, report and transfer files on a daily basis. Webpages were loading slowly
and file transfers took a long time because of the network distance and uneven
performance of the Internet.

The following data shows the response times with the original access solution.

This poor performance impacted employee productivity. To solve these issues and to
reduce the MPLS monthly cost, Lenovo decided to try the SD-‐WAN solution provided
by AppEx Networks: CloudWAN. Lenovo connected to CloudWAN’s nearest PoP
from its Beijing HQ, then connected to Workday through another Cloud PoP near its
Washington D.C. servers. To guarantee high availability, a backup PoP was assigned
to Lenovo at the same time for redundancy. Lenovo users can now connect to the
Workday application quickly and with good performance. Below is a picture of the
current configuration:

With CloudWAN, the latency and packet loss were reduced dramatically. The rate of
packet loss was almost zero. This clearly shows that CloudWAN provides a stable
data transfer rate.

Summary:
CloudWAN improves cross-‐boarder application access in the following ways:
l CloudWAN leverages AppEx asymmetric TCP acceleration technology,
which also improves the performance of mobile offices;
l CloudWAN provides dynamic route optimization managed by an SDN
centralized controller, which guarantees high availability;
l Global PoP distribution breaks the boundaries between countries. PoPs
can be expanded quickly based on business requirements;
l AppEx RTT Tunnel secures customer data with encrypted data transfer;
l CloudWAN can be setup within one day: and there is no setup fee, which
can save customers up to 60% in initial costs.
