The Unified Network Services (UNS) portfolio of Layer 4-7 services (such as ACE and WAAS) also includes Cisco’s data center security solutions. A critical part of that security portfolio is our virtualization-aware firewall solution, Virtual Security Gateway (VSG). In a series of upcoming blog posts, I’ll be sharing a few use case scenarios that our customers are implementing with VSG.
For those of you new to VSG, I’ll point out that VSG’s role is to act as a virtual firewall between zones of virtual machines. Isolating traffic between VM zones has been very challenging prior to VSG because: 1) security policies have to be enforced between VMs running on the same server or same virtual switch (where there’s no place to put a firewall), 2) VMs move all around the network and the security policies (as enforced in the firewall) must follow the VM, and 3) the need to maintain segregation of duties for compliance purposes between the security and application server teams, where security is potentially enforced inside the virtual server.
Unified Network Services (UNS) is the portfolio of L4-7 network services and data center security products within the Data Center Business Advantage architecture. This week’s UNS spotlight is on Cisco’s Network Analysis Module (NAM), which provides network administrators deep visibility into network traffic and applications to help ensure consistent and cost-effective delivery of service to end users.
NAM is the foundation for establishing and verifying quality of service (QoS) policies, undertaking WAN optimization projects, and rolling out voice over IP (VoIP). It can also detect when configuration changes inadvertently degrade application performance, and provides clear insight towards rapid remediation. Consistent with many other UNS portfolio products, the NAM product family includes integrated service modules, virtual service blades and stand-alone appliances offering deployment flexibility and consistent performance visibility from the branch to the data center.
As a proof point of Cisco’s unified L4-7 service offerings, NAM offers end-to-end application performance visibility for Cisco Wide-Area Application Services (WAAS) deployments to help maximize your WAN acceleration efforts. NAM can help identify candidate sites and applications that will benefit the most with WAN optimization while quantifying and validating the impact of WAAS on application and network performance. The real-time visibility can also be used for ongoing optimization and troubleshooting performance degradation. The following graph shows the immediate impact of WAAS on transaction time for a particular application.
