Performance Management
Application Performance
Management
The end-to-end performance of networked applications depends on complex interactions among applications, servers, and networks. Effective application performance management requires taking a true "end-to-end" view by understanding the application from these multiple perspectives.
Application performance management is needed throughout the application lifecycle, beginning with development and QA, and continuing through deployment and operations. A comprehensive strategy requires analytics that enable both rapid troubleshooting and proactive prevention of problems.
Caspian's Application Performance Management (APM) solutions ensure that applications will perform effectively in production, that systems have adequate capacity to support them, and that networks that deliver application functionality can meet service level objectives.
A Better Understanding
of Network Interactions
What's happening in information technology drives the developments in enterprise networking. The level of complexity in the IT environment is growing at an accelerated rate as high-priced enterprise-class application software packages are acquired along with the hardware/software infrastructure required to support these sophisticated and complex systems.
These enterprise software systems, particularly when mixed with legacy applications, function on a complex set of interactions with the network infrastructure. Some application systems are highly sensitive to latency, while others are highly bandwidth intensive. With the current generation of e-business applications having to co-exist on the same network infrastructure as legacy applications, demand for network resources will impact, usually negatively, the performance of all of the applications and, hence, your business.
Understanding Your Application Interactions is Critical to Your Success
Multinational corporations implementing enterprise-class software packages face enormous and complex challenges. The ability to deal effectively with the very complex interactions between the network infrastructure and widely distributed applications is a priority.
Typically, the networking experts are not involved upfront in the decision making process regarding which application software package best suits the business requirements. They become involved after the fact, which often requires the Wide Area Network (WAN) to be re-engineered to support the application. Unfortunately, this "easy fix", exposes the enterprise to four risks:
- Over-provisioning
- you pay more for the network than necessary.
- Under-provisioning
- your network lacks appropriate resources and
end users are dissatisfied.
- Application Conflicts
- you must re-engineer the WAN to deliver acceptable
performance to a globally dispersed user population.
- Reset User Expectations
- you must spend additional time and money training
users and lowering their network expectations.
How Application Performance Management improves productivity and profitability
Application Performance Management (APM) is a logical process that begins by first understanding your company's business objectives. Enterprise applications can then be prioritized based on the impact each application has on these business objectives. Caspian then can predict and measure the impact of business applications on existing and planned network infrastructure. Caspian can also model the impact the applications and alternative network designs will have on business processes using a unique and proprietary return on investment analysis tool.
We have experience with measured performance profiles and baseline data on popular packaged applications such as: SAP, Siebel, Baan, PeopleSoft, Oracle, JDEdwards, Lotus Notes, Documentum, Vantive, SMTP mail, HTTP Web, and CITRIX. These results help us model how these applications will perform on YOUR network in YOUR enterprise networking environment.
Application Performance
Assessment Overview
Unlike other approaches that equate more applications with more bandwidth, Caspian demonstrates that optimum application and network performance occurs when the dynamics of applications, protocols, and traffic flows are measured and understood. Caspian's consultative methodology uses our Application Performance Analysis to quantify the relationship between applications, networks, and business objectives as well as generate a Return on Investment (ROI). We take the guesswork out of how to optimize your strategic investments and de-risk deployments.
This type of an engagement will support the capture and investigation of application modules identified by our client as having performance issues. It will provide detailed analysis of the application modules with a look at the impact the application will have on the client network and the responsiveness of the applications given the client's existing and potentially future network infrastructure. We will use a combination of transaction capture and interview techniques to form assumptions regarding use and concurrency in the field when creating the dataset for the network modeling and performance parameter portions of this type of an engagement.
Assessment and Discovery
Caspian will acquire current client production network data with respect to current state usage, traffic, sites, and users via a combination of information gathered during the baselining analysis as well as interview with key personnel to be utilized as needed in subsequent stages within the scope of this project. Through completion of this element our client gains a more thorough and understandable picture of current state configurations and contributory performance factors. For those locations not currently using the stated application, our client will combine the stated application transactions captured with our extensive library of application data and will create "profiles" by location based upon known factors such as geography, personnel function and utilization, and traffic impact.
Network Insight Application Profile
Caspian will create a profile of the application modules defined to be captured directly from our client with detailed analysis of the interaction of the application across a network and between tiers. This information provides details on potential modifications to application, systems or infrastructure that could dramatically improve not only the applications network usage pattern but also the end users experience. This element also includes the process of capturing, generating or overlaying specific client application profiles into a simulated and modeled environment if required. Based on the environment presented in previous elements, preliminary information is compiled with respect to the network delta of applications and the relevant characteristics of each application on the network. The new modules will be captured for initial analysis and we will use a combination of actual transaction capture statistics as well as interviews and assumptions gathered from client personnel to develop the dataset for the modeling initiative as questions remain regarding both functionality use and concurrency.
Summary Report
The finished analysis will produce an output study and report with a delta report and network impact summary for the proposed network and selected application changes or additions. Recommendations and findings will be presented on how best to optimize the applications in question through augmenting the application, modifications to systems services or through network infrastructure or parameters. Detailed information is provided in the form of a Compact Disk containing data that is easily accessible as ".html" pages using any common Internet Browser program.
