SaaS collaboration applications
Infrastructure directors are under tremendous pressure from business stakeholders to adopt cloud-based SaaS applications with expectations of lower IT costs, greater business agility and a better user experience. Cloud computing brings the promise of simplified application delivery, but at the expense of underestimating the additional network complexity.
Bandwidth requirements vary for SaaS applications. Collaboration applications such as Google Apps, Microsoft BPOS /Office 365 and IBM LotusLive have a significant larger impact on network traffic than the on-premise applications being replaced. Collaboration consumes more bandwidth per user, increases WAN usage for internal communications and is more likely to be extended to more workers.
The bandwidth involved with SaaS is not the only network issue. The way traffic flows across the WAN can change dramatically when SaaS applications are used. Collaboration traffic no longer flows between a data center and branches but between one, a few or many Internet gateways to the branches.
As a result, SaaS integration projects that were initially considered to be easy, cost-effective and fast can become progressively difficult, expensive and slow to implement. The cost advantages of moving to SaaS can be neutralized by the greater workload and expenses for network management.
ANS-native SaaS Application SLA enforcement secures performance during and after deployment. SaaS Application Performance Objectives and KPIs fully control application delivery over the network. Driven by Application Performance Objectives, ANS ensures that both public SaaS applications and private data center applications get delivered according to SLAs as new users or sites are added. Before, during and after the SaaS deployment, Application Quality Score® (AQS) indicators allow IT managers to monitor application performance and understand the impact of SaaS rollout on the WAN. Native SaaS support encompasses popular applications such as Google Apps, Office 365, LotusLive and Salesforce.com. Enterprise can add others in a few mouse clicks.
