Applications have moved to the cloud. Even traditionally on-premises applications, such as Microsoft Office, have transitioned into SaaS-based offerings. So, more organizations are relying on applications that are serviced from SaaS network infrastructure that they don’t own, connected over Internet networks that they don’t control. Regardless of who owns the application, IT still owns user experience. But ensuring a high-quality user experience can be challenging because of the complexity of the service delivery chain. With SaaS applications, users rely not only on the SaaS provider’s infrastructure but also on many external dependencies, such as DNS, ISPs, CDNs and DDoS protectors. All of these must be working seamlessly in order for users to have a good experience.
Traditional network monitoring tools using packet capture, flow data and SNMP don’t provide visibility outside an organization's boundaries. As such, legacy network monitoring products that employ these techniques do not provide adequate SaaS application visibility, nor do they combine together effectively across siloed data sets to offer a capable suite of SaaS monitoring tools.
