1 Interested in True Network? Measure it From an Application Perspective.

2 The Singular Importance of Application More than ever before, applications are becoming the lifeblood for most organizations. Consider online retailers, insurance providers, banks or any company that delivers a service over the cloud. Their entire brand identity is wrapped up in the performance of their applications, which means that any service delays or interruptions can quickly translate to lost customers, reduced revenue and a damaged reputation. To ensure that their applications can deliver the level of service customers expect, many of these organizations have invested in application performance management (APM) and/or network performance management (NPM) products that provide visibility into applications themselves and the performance of network devices and long-distance links, respectively. The problem with this approach, however, is that APM and NPM operations are often built up in silos meaning little integration or communication occurs between the teams monitoring them, save for when performance degradations occur, and then the blame game begins. In today s landscape where application performance is everything, it s clear that a new approach is needed one that assesses network and application performance both in context with each other and in how they impact the business. 02

3 The Need for Application-driven Network Management (ANPM) Network managers can no longer be concerned with just interoperability and uptime. They need to recognize and eliminate application performance issues in real time or before they even occur a method that requires a direct understanding of how applications and services are performing over the network they are sharing. What does this mean? Organizations must begin transitioning from siloed APM and NPM operations to an application-driven network performance management (ANPM) perspective that puts the health and operation of the network in context with the services being delivered to end users. With the right ANPM solution, the network group becomes more intricately tied to overall organizational success, as opposed to just keeping the lights on or being the first point of blame when performance issues occur. And because ANPM represents a new way of thinking about performance management, it s important to examine how it can positively impact specific use cases within the enterprise. With ANPM, network professionals can shift their focus from keeping the lights on to directly supporting organizational goals. 03

4 Four Areas Where ANPM Can Improve Network Management The recent focus on application performance demands a more proactive approach to identifying and addressing potential network performance degradations. With the right ANPM solution, organizations can transition to such a proactive approach in four key areas: Troubleshooting Capacity Planning Optimizing the WAN Providing Highquality Unified Communications 04

5 Troubleshooting As most network professionals are quick to admit, troubleshooting performance problems represents a significant portion of their day-to-day duties. By connecting network performance to application performance, an ANPM solution can help them avoid time wasted on back-and-forth finger pointing and expedite problem resolution. Troubleshooting Capacity Planning Optimizing the WAN Without ANPM: Primary focus is on deflecting blame and/or keeping the network up, versus optimization and innovation issues are detected and resolved in a manual, reactive way, requiring additional IT time and costs Quality of Service (QoS) policies are not optimized to reflect the evolving demands placed on the network WAN visibility shows overall bandwidth usage, but not what applications are running on the network or which of those applications and hosts are consuming the most bandwidth slowing triage and resolution times With ANPM: Primary focus is on the end-user experience and how users expectations can be met Anomalous activities are automatically detected and actions are assigned based on impact to application performance and end-user experience QoS policies evolve as application needs grow and change over time WAN visibility includes knowing where problems are occurring, who is consuming bandwidth and what is threatening performance Providing Highquality Unified Communications 05

6 Troubleshooting Capacity Planning It s no secret that networks and the operations they support grow and change over time. Whether in response to mergers and acquisitions, the launch of a new product, technology or service or another major initiative, organizations can leverage usage and activity data pulled from an ANPM solution to justify network capacity needs and effectively plan for the future. Capacity Planning Optimizing the WAN Without ANPM: Capacity planning is an educated guessing game Additional bandwidth is thrown at problem areas, sometimes resulting in overprovisioned assets that can be costly Infrastructure investments are made reactively on an individual, as-needed basis, making it difficult to scale in an agile and effective way With ANPM: Capacity planning is based on historical, trend and benchmark data pulled from the network Bandwidth is intelligently distributed based on traffic patterns, critical application requirements and QoS policies Infrastructure investments are made holistically with consideration for application rollouts, potential bottlenecks and future capacity needs Providing Highquality Unified Communications 06

7 Troubleshooting Optimizing the WAN As a companion use case to capacity planning, WAN optimization is all about maximizing existing investments and increasing the cost efficiency of the network infrastructure. The right ANPM solution will enable network professionals to access important network data, including traffic flow information, and perform advanced analytics in order to determine the most productive and effective distribution of network resources. Capacity Planning Optimizing the WAN Without ANPM: New investment and/or upgrade decisions are made before existing resources have been adequately tested and reconfigured Limited visibility into usage patterns leads to inefficient workload scheduling and QoS policies Additional costs are accrued through unnecessary investments and staff implementation/management time With ANPM: Long-term, historical data can be used to maximize existing resources and delay or prevent additional investments/upgrades Holistic visibility helps drive effective workload scheduling and QoS policies, optimizing the network for application performance Additional costs are avoided through optimum utilization of resources and network professionals time Providing Highquality Unified Communications 07

8 Ensuring Unified Communications (UC) As unified communications (UC) technologies that run over an organization s IP network have grown in popularity, the services they power (e.g., voice over IP (VoIP), video and teleconferencing, etc.) have occupied increasingly large swaths of network bandwidth. The right ANPM solution will empower network professionals to proactively protect and assure the availability and performance of UC applications, rapidly troubleshoot and restore services when issues arise and ensure that UC applications and critical data applications are allocated the type of service each requires. Without ANPM: With ANPM: Troubleshooting Capacity Planning Optimizing the WAN Providing Highquality Unified Communications Heavy, unpredictable bandwidth demands cause performance degradations in UC and other applications QoS policies may not support the unique service qualities required by VoIP and video Limited data-collection and analysis capabilities prevent network professionals from assessing UC performance in the context of how it affects other critical applications Effective monitoring of voice and video quality metrics helps ensure a high-performance UC experience Visibility into voice and video performance metrics in context with metrics for other critical applications ensures that QoS policies are meeting the needs of all application types Visibility into activity across the infrastructure enables IT staff to quickly identify where incidents are occurring, what is the cause and what users and applications are impacted 08

9 Assessing the Benefits of ANPM The common element in how ANPM affects each of the aforementioned use cases is a switch from reactive, break/fix, trial-and-error network management to a more proactive approach that leverages historical and real-time data to maximize network resource utilization and support the organization s most critical applications. Additionally, ANPM can help organizations achieve the following business benefits: Accelerated troubleshooting helps improve application performance and the end-user experience, while also increasing network professionals productivity Improved WAN optimization helps maximize the use of existing assets, while clearly identifying where and when new assets are needed Enhanced capacity planning helps the business anticipate changing traffic demands and scale cost-effectively to meet future requirements Increased UC performance helps improve collaboration among users, increase their productivity and support efficient operations 09
