Software as a service (SaaS), one of the earliest and most successful cloud services, has reached mainstream status. According to Cisco, by 2019 more than four-fifths (83 percent) of all data center traffic will be based in the cloud, up from 65 percent today. The majority of this traffic will be applications.
Businesses of all sizes are adopting a variety of SaaS-based services – everything from collaboration tools to mission-critical commerce-oriented applications. The rise in SaaS usage has many positive benefits, but one drawback is that as demand grows, SaaS providers are having a harder time ensuring a high-performing (fast, reliable) end-user experience – at the same time performance expectations are growing higher than ever.
