Software-as-a-Service (SaaS) deployments are irresistibly appealing to organizations of all sizes, especially those with multiple sites. From browser-based access, to painless installations and upgrades, to minimal IT overhead, seamless scalability, and lower TCO, SaaS is a smart, cost-effective option.
SaaS differs from “cloud” in that SaaS applications can be hosted inside a company’s firewall, as well as remotely. More and more businesses are using SaaS for mission-critical applications like e-mail, financial management, ERP, backup and disaster recovery, HR management, collaboration and CRM.
But, by definition, SaaS solutions are accessed over a network – and therefore run into performance challenges, threatening service degradation and more often failure.
Most SaaS deployments are significantly more sensitive to network performance and availability than traditional, on-premise software or even transaction-based network applications like e-mail. This is equally true for a wide range of network-dependent services not generally considered “SaaS,” such as VoIP, video conferencing and virtual desktop infrastructure.
These mission-critical services depend on high-bandwidth, low-latency networks to deliver an acceptable user experience. Issues such as packet loss, latency and jitter can make today’s performance-dependent networked services fail – abruptly! When calls and video sessions are dropped, backups don’t happen and business software disappears into the “cloud,” and business stops.
The quality of users’ experience is a defining factor in the success of a SaaS deployment. But how do you measure service quality or adherence to SLAs from a remote user’s viewpoint? How do you know when service is degraded or what to do about it? This lack of visibility into the remote user’s experience of hosted services is a major stumbling block preventing organizations, from SMBs to large enterprises, from enjoying the benefits of SaaS.
A survey of network managers released in March 2010, found that 50% of cloud consumers have no performance measurement SLAs and 75% of cloud users are unable to measure network performance between their users and the cloud provider.
Remote Performance Management enables remote, real-time monitoring of whatever network(s) your SaaS applications or other IP-based services are running on, whether hosted remotely, in-house, or a combination of both.
With Remote Performance Management you can measure end-to-end service quality, troubleshoot performance degradation and pinpoint network problems. Available as a cloud-based service, it takes minutes to install, is highly scalable and cost-effective for organizations of any size.
