Application Acceleration The IT infrastructure in organizations is continuously evolving to support more and more business critical applications that enable growth, operational excellence and competitive edge. Multi-tier applications involve transaction paths from servers, storage, networks, middleware, databases, and clients. All these active components add delays to the end user transactions degrading the overall application performance. This situation gradually aggravates to a level impacting business operations losing customer confidence and revenues. Identifying any optimization solution without clearly understanding the root cause for the performance issues often results in huge capital and operational expenditures. Let us take a typical scenario of a business application performance troubleshooting. 1) A critical application becomes slow. The user complaints are logged at the help-desk. 2) The network team is engaged. They typically come up with latency and packet drop reports. Both these reports are normal. 3) The system administrators are the next ones in the troubleshooting process. They typically come up with server CPU and memory utilization reports. Both these reports are normal. 4) The Application team would now get engaged for the problem resolution. They come up with the application level request/response logs and these reports also look normal. 5) In the absence of an acceptable performance benchmark and enough data to validate and pinpoint the root cause, the blame game resulting in no ownership of the problem. 6) Problems are usually addressed by adding a tactical “solution” or product which does not address the entire scope of how the application is delivered and probably does not address the growing needs of the company.
The gap in addressing the application performance issues is mainly due to the following reasons
1) An increasingly complex application delivery infrastructure. 2) Lack of ownership. 3) Lack of tools that can collect and correlate information from multiple components in the infrastructure to identify the root cause. 4) Lack of expertise in analyzing as well as measuring the effectiveness of a particular solution by understanding the individual technology components and utilizing their respective benefits.
In order to bridge the gap, basic questions need to be answered:
1) What is the definition of application performance? 2) What needs to be monitored / measured? 3) What is the acceptable performance matrix? 4) Can performance be achieved with the current infrastructure? 5) If not, how can the performance requirements can be met? 6) Where are the performance issues in the system? Are they at the application level, compute infrastructure level or network level? 7) What is the best-practice approach in solving these performance related issues? 8) What technique / technology / product are best suited for each problem identified? 9) How to evaluate the cumulative effectiveness of the solution? 10) How will it affect the other components in the system? 11) What if my network changes or grows? Is the solution deployed adequately scalable to meet business change? 12) What is the return on investment (ROI) as well as Total Cost of Ownership (TCO) ? Finding answers to these questions can potentially help your business to scale and realize greater customer satisfaction. Business Acceleration Service (BAS) is developed to address all of these challenges and provide tangible answers and solutions to resolve these performance related issues. Apara with its industry experience in delivering similar performance optimization solutions in Storage, Networking and Security has come up with a well defined methodology to deliver the service based on industry best practices, processes, best-of-breed tools as well as highly trained and certified domain experts / consultants. The approach involves four stages with clearly stated deliverables. The stages involve Plan, Measure, Assess and Optimize as shown below.
The tangible and intangible benefits of optimization are studied to arrive at TCO / ROI models to enable organizations to make strategic decisions for their business.
