Performance Testing And Validating Systems Before Deployment Of Production Environments

In these paper author focus on finding the gap in understanding how complex individual Web sites are and how this complexity impacts on the usersperformance. Also characterize the Web site both at content level (like, number and size of images) and service level (like, number of servers/origins). It may happen that some categories are more complex than other such as 'News '. Out of hundred 60% of Web sites fetched content from minimum five non-origin sources, and these give more than 35% of the bytes downloaded. In addition, they examine which metrics are most suitable for predicting page render and load times and catch that the number of objects requested is the most important factor. With respect to variability in load times, however, they alsofind number of servers is the best indicator.

Cloud computing is on the rise. Cloud computing is a style of computing where software and virtualized hardware is provided over the internet (O’Brien & Marakas, 2011). The seven most common uses of cloud computing include: infrastructure as a service, private cloud or hybrid cloud, test and deployment, big data analytics, file storage, disaster recovery and backup (Ferkoun, 2014). The biggest advantages of cloud computing include increasing competitiveness through cost reduction, greater flexibility, and elasticity and optimal resource utilization (Ferkoun, 2014). Cloud computing basically uses the internet to provide for the computing needs of the end users.

Web testing is the name given to the software testing of web applications. Web applications are the applications that are ultimately meant to be viewed by user, so maintaining the quality of these applications is a major concern. This report focused on finding the software testing methods that are currently used to test functional and non functional requirements of web applications efficaciously. This paper also covers the challenges that are introduced while testing web applications. A web application is basically different from traditional software application in the sense that former one has large number of users which are accessing the web application simultaneously. Secondly, web application is based on different hardware, operating system and network connections. The different web components are constructed from different programming languages and different models. The aim of web testing is to execute the application in multiple platforms and in multiple environments to reveal failures. Failure is either caused by the faults in application itself or in the interface and faults in the running environment.

To prove just how important speed is to your web presence, I tested two of the biggest websites on the planet...

Microsoft’s internet information services (IIS) is one such solution. This webs server is designed to run on Windows server platforms. Consequently, it integrates well with Microsoft’s online applications. It features an intuitive graphical user interface that simplifies its installation and use. However, the costs of installing new versions of this web server are high. In addition, its restriction to the Microsoft server OS platform inhibits system flexibility. An alternative to IIS is the Apache web server. This is an open sourced application that can be implemented on a wide variety of operating system platforms. Apache’s integration of a pearl and PHP engine facilitates easy integration with the application programming interface (Gunther, 2006). In addition, this web server is available for free. This makes it a cost effective alternative. Further, Apache’s event-driven architecture enables it to perform ideally even under heavy loads. However, Apache usage involves a relatively strenuous learning curve. The software’s complexity may present an obstacle to its use by new users. Another web server that can be adopted for use in this project is Nginx. This server is easy to use as well as stable. It is also based on an event driven architecture. This architecture makes it an efficient user of system resources even under heavy loads (Tanenbaum, 2001). Nginx’s ease of installation, configuration, and use make it a viable alternative for adoption in

When considering a solution that benefits both its owners and its users, Dedicated Servers are often the resolution to the problem of not having enough processing power or flexibility for one’s website. A server in itself is defined as a device that offers a functional environment for users to run programs or separate devices. Even though many use these servers for databases, multiplayer gaming, and applications, numerous use them as businesses to host their own website. In comparison to the smaller, less expensive idea of a shared webhosting service, Dedicated Server’s often give you improved reliability and more freedom overall. Due to business owners having relatively high traffic on their websites, it is often

This research report was to understand the background of the software architecture and how it interrelates with the architecture of web browser. Having a working reference that could be used for the project will help both during maintenance and design time.

First we determine whether PESA would be a significant improvement, making use of the figures in Exhibit 2. As the web server hosting performance goes up by roughly 409%, and this being

Main the main changes in hyperscale computing include: local network-connected storages substitute the traditional array of storage networks, virtual LANs takes over dedicated computing, commodity network elements replace network switching, commodity computing components substitute blade systems, and new applications and software replace the existing hardware devices meant for tracking and monitoring.

Testing different websites’ versions is the best process to control improvements. Although it sounds like a simple changing features activity, testing is a big challenge that often involves teams such as marketers, designers, researchers, and analysts, which makes the testing process even harder. The risk of failure on the experiment is higher when the test is built based on the team’s insights only and not on the users’ point of view. However, it is important to try different types of testing to uncover possible root causes of a drop in the website traffic and make wise decisions to fix it.

Cloud Computing is an innovating new IT service that enables multiple services like storage, web hosting and computing under the same roof. Many companies are moving their services to this technology with the flexibility of “pay as you go” model where a customer pays only for the services used leading to cost saving for them. It also helps in terminating the need for large infrastructure maintenance and development. Multiple Virtual Machines (VMs) having varying resource locations can be operated together by a physical machine through utilization of hardware virtualization by Clouds [1]. There can be an imbalance in a PM due to a varying load of each VM due to over load of resource demand and it can affect the performance of VMs on the PM

The main driving forces of cloud data storage are reputable companies such as Amazon and Google building comprehensive computing infrastructures (Google, 2009). These infrastructures are removing the complexity of in-house data storage and ultimately reducing costs of limited networked data centres (Hitachi, 2010). The traditional inefficient model of purchasing servers every time you need to accommodate for high use or growth is now being replaced by internet based systems that replicate your data centres but without the big overheads (Google, 2009). This flexibility assists in the ever changing business world and its continuous improvement initiatives to remove waste, improve efficiency, and ultimately reduce costs. Another key driving

Web servers are characterized mainly by low CPU utilization with spikes during peak periods, with disk performance as a consideration if the website is delivering dynamic content (Advanced Micro Devices, 2008). Traditional web servers only delivered static HTML pages, or pages that had no interactive or data-input elements – merely a send and read operation. Dynamic websites may utilize forms and databases, which would be an additional consideration to a high traffic website.

With the increase in demand, high performance systems have to be increasing their level of performance, availability, accessibility, security and scalability for the business continuity.
