Pylot - Performance & Scalability Testing of Web Services

Pylot is a free open source tool for testing performance and scalability of web services. It runs HTTP load tests, which are useful for capacity planning, benchmarking, analysis, and system tuning. Pylot generates concurrent load (HTTP Requests), verifies server responses, and produces reports with metrics. Tests suites are executed and monitored from a GUI or shell/console.

weathervane - Virtual-Infrastructure and Cloud Performance Benchmark

Weathervane is an application-level performance benchmark designed to allow the investigation of performance tradeoffs in modern virtualized and cloud infrastructures. It consists of an application, a workload driver that can drive a realistic and repeatable load against the application, and a run-harness that automates the process of executing runs and collecting results and relevant performance data. It can be used to investigate the performance characteristics of cloud and virtual infrastructures by deploying the application on the environment of interest, driving a load against the application, and examining the resulting performance metrics. A common use-case would involve varying some component or characteristic of the infrastructure in order to compare the effect of the alternatives on application-level performance.The figure above shows the logical layout of a Weathervane deployment. The Weathervane application is a web-application for hosting real-time auctions. This Auction application uses a scalable architecture that allows deployments to be easily sized for a large range of user loads. A deployment of the application involves a wide variety of support services, such as caching, messaging, NoSQL data-store, and relational database tiers. These services can be deployed in VMs or in Docker containers. The number of instances of some of the services can be scaled elastically at run time in response to a preset schedule or to monitored performance metrics. In addition, Weathervane supports deploying and driving loads against multiple instances of the Auction application in a single run, thus enabling performance investigations of resource constraints or other aspects of multi-tenancy. The Weathervane run-harness manages the complexity of configuring, deploying, and tuning the application, automating most of the tasks involved in configuring the application services and running the benchmark.

Visual cryptography is a powerful technique which combines the notions of perfect ciphers and secret sharing in cryptography with that of raster graphics. A binary image can be divided into shares which can be stacked together to approximately recover the original image. The physical transparency stacking type of decryption allows for the recovery of the traditional visual cryptography quality image. In this paper, quantification and analysis is done based on various performance parameters of vi
