Citrix has acquired Cedexis, a company that provides a DNS service that can steer requests based on real-time performance data.
Cedexis collects a variety of metrics to measure the performance of cloud services, CDNs, and service providers. Using these metrics, Cedexis can make more informed traffic management decisions.
As a simple example, if a user in New York goes to a Web site, the closest geographical data center to serve that site might be in New Jersey. But if the connection is congested, a faster response might be available in Virginia. Cedexis will steer the request to the better-performing location.
Cedexis includes a programmable interface so that organizations can build business logic into their traffic management decisions. Organizations can set up controls based on performance, cost, geographical location, or local regulations.
Cedexis gathers information via a tag that’s served to users’ browsers. This tag then gathers information on HTTP response times, throughput, error rates, page loads, and other metrics (more details are available here).
What was Citrix’s interest in this company? According to Steve Shah, VP of Product Management, it aligns with one of the pillars of Citrix’s cloud strategy, which are built around:
- Access security
- Application security
- Intelligent traffic management
The overall goal of this strategy is to help customers deliver the best possible application experience in a multi-cloud environment that stretches from the data center to the public cloud.
Shah said in a briefing that Cedexis can, for example, supplement NetScaler’s ADC. “NetScaler has a presence in the data center and cloud, so now we can get more insights from the public Internet.”
Citrix did not disclose the amount it paid for Cedexis.
