Dynamic Provisioning of Multi-tier Internet Applications

Abstract: Dynamic capacity provisioning is a useful technique for handling the multi-time-scale variations seen in Internet workloads. In this paper, we propose a novel dynamic provisioning technique for multitier Internet applications that employs (i) a flexible queuing model to determine how much resources to allocate to each tier of the application, and (ii) a combination of predictive and reactive methods that determine when to provision these resources, both at large and small time scales. Our experiments on a forty-machine Linux-based hosting platform demonstrate the responsiveness of our technique in handling dynamic workloads. In one scenario where a flash crowd caused the workload of a three-tier application to double, our technique was able to double the application capacity within five minutes, thus maintaining response time targets

Application Performance Management in Virtualized Server Environments

Abstract: As businesses have grown, so has the need to deploy I/T applications rapidly to support the expanding business processes. Often, this growth was achieved in an unplanned way: each time a new application was needed a new server along with the application software was deployed and new storage elements were purchased. In many cases this has led to what is often referred to as "server sprawl", resulting in low server utilization and high system management costs. An architectural approach that is becoming increasingly popular to address this problem is known as server virtualization. In this paper we introduce the concept of server consolidation using virtualization and point out associated issues that arise in the area of application performance. We show how some of these problems can be solved by monitoring key performance metrics and using the data to trigger migration of Virtual Machines within physical servers. The algorithms we present attempt to minimize the cost of migration and maintain acceptable application performance levels.

Web survey tool builder and result compiler

Abstract: The present invention relates to a software tool that permits creation of electronic surveys and the automatic collection and tabulation of survey results corresponding to user responses. Using the tool, a survey is automatically created and posted at a Web site address. With a Web client, or browser, computer users access the URL and complete the survey via the Web. Survey results are collected in a relational database as each user completes the survey. Thereafter, statistical tools or other analytical software applications may be applied to data mine the tabulated results. In another preferred embodiment, the software tool is utilized to access remote servers running relational databases from an internet computer via the Web. Advantageously, the computer does not require the computational processor power or memory (i.e. system memory or disk storage capacity) normally required to load and operate the applicable relational database application software.

Distributed shared memory: concepts and systems

Abstract: In surveying current approaches to distributed shared memory computing, the authors find that the reduced cost of parallel software development will help make the DSM paradigm a viable solution to large scale, high performance computing.

Software Architecture Reconstruction: A Process-Oriented Taxonomy

Abstract: To maintain and understand large applications, it is important to know their architecture. The first problem is that unlike classes and packages, architecture is not explicitly represented in the code. The second problem is that successful applications evolve over time, so their architecture inevitably drifts. Reconstructing the architecture and checking whether it is still valid is therefore an important aid. While there is a plethora of approaches and techniques supporting architecture reconstruction, there is no comprehensive software architecture reconstruction state of the art and it is often difficult to compare the approaches. This paper presents a state of the art in software architecture reconstruction approaches.
