Microsoft Office365, Salesforce, Dropbox, etc. are business-critical SaaS applications. There are three primary methods, used by the Enterprise to offer SaaS applications connectivity for their users:
• Direct Internet Access (DIA) from the branch office.
•internet access through a regional facility.
• Cloud exchange/ direct connection through gateways in a Carrier Neutral Facility (CNF).
The performance of these applications isis directly affected by latency and packet loss, but network administrators have limited visibility into the network performance characteristics between the SaaS applications and end-user. In case of path impairment and degraded application performance, the network administrator needs to follow a set of complicated, manual, time-consuming, and error-prone steps to shift traffic from a primary to its’ alternate path.
Visibility and continuous monitoring of network performance are the two major benefits of Cisco SD-WAN Cloud onRamp for SaaS. The real-timeThe real-time decision is made by choosing the best performing path between an end-user and the SaaS application for an optimal user experience. The network performance changes automatically, as the application traffic is re-routed away from any degraded network paths.
All three access methods for cloud-based SaaS applications are supported in Cloud onRamp for SaaS, including DIA, internet access through a regional facility, and through gateways in a Carrier Neutral Facility (CNF).
An application performance value, known as the Viptela Quality of Experience (vQoE) is calculated by Cloud onRamp for SaaS for enterprise cloud applications. For each and every individual application, the vQoE value weighs loss and latency. For example, latency for email applications is comparatively higher than video applications, and video applications may tolerate loss higher than an email application does. The vQoE value ranges from 0-10, where 0 is the worst quality and 10 is the best.
Cloud onRamp for SaaS needs to be enabled on Cisco vManage, and then the Cloud onRamp dashboard in Cisco vManage can be accessed for continuous visibility related to the performance of individual applications.
