Server Virtualization Server virtualization refers to logical partitioning of a server into multiple servers in which each logical server has its copy of the operating system, applications and other resources to mimic the functionality of a physical server. This can be achieved with the help of a software called as Virtual software that enables the creation of logical systems called as virtual machines each virtual machine is an autonomous, isolated virtual system that behaves precisely similar to that of a physical system with the same configuration. The need of server virtualization: Most of the organizations have several servers and systems in their IT infrastructure but never use their processing resources up to an optimal level thereby resulting in wastage of resources in terms of maintenance costs and establishment costs. In such a case, the available processing capabilities could be virtualized such that it reduces the requirement of additional hardware resources to meet the increase in processing and computing demands in future. So, virtualization benefits in reducing the expenses involved in the establishment and maintenance of IT infrastructure in the small…
Building a Computer Security Incident Response Team (CSIRT) A Computer Security Incident Response Team (CSIRT) is needed for an organization to deal with computer threats in the right manner (Horne, 2014). Different organizations use various approaches when it comes to creating a CSIRT team. In most cases, the first step seems to be the same. When building a CSIRT team, there is a need to inform the responsible people about the idea. The people will be in a position to support where necessary. In most cases, the managers in different departments are the ones who are first informed. After getting the right support, there is a need to decide what type of CSIRT team to build. The type of the CSIRT team to build will differ with the kind of members who form the team. A CSIRT team can have full-time employees or part-time employees. An organization should decide what type of members to have according to their needs. In most cases, organizations prefer having full-time employees. The reason behind this is the fact that the full-time employees will be…
Cloud Computing: Models, Benefits, and Limitations Cloud Computing Organizations tend to develop an entrepreneurial culture through a strong orientation toward innovation. Cloud computing refers to a computer-enabled architecture that provides flexible and scalable IT-enabled capabilities as a virtual service through the internet. Cloud computing technology is characterized by resource pooling, broad network access, on-demand self-service, rapid elasticity, and measured services (Mohamed, 2018). Consumers that use cloud computing technology strive to integrate many services from a central point that is conveniently accessible from any device linked to the system. Some of the resources include virtual storage units, processors, and network bandwidth. It is a developing technological trend that was adopted in the late 1990s. The pay-as-you-go on-demand computer infrastructure and resources are owned, operated, and managed by various service providers (Mohamed, 2018). Some of the renowned cloud computing service providers include Amazon, Oracle, SoftLayer, and Microsoft. The History of Cloud Computing JCR Licklider pioneered the development of ARPANET (Advanced Research Projects Agency Network) in 1969. He had a vision of interconnecting everyone across the globe to enable them to access data…
California Research Paper Introduction Package pilferage is the theft of part or whole of contents of a package. Package pilferage also includes theft of the contents in it and leaving the package. Small portable packages can easily be stolen from a large package like a big container for shipping. Theft of mail, on the other hand, includes taking or stealing any posted item, including postcards or packages. Such crimes do not always require the use of force by the perpetrators. Therefore, federal law in the definition of crime often includes them because they majorly involve taking of items through deception, fraud, or embezzlement. Thisresearchaims to explore package theft in San Francisco, federal and California state laws passed to combat it, San Francisco city laws, and the role the law enforcement agencies play in combating this menace. Other related and broader aspects of mail/package theft include taking the whole package, truckload, shoplifting, etc. Theft of packages can take place anywhere in the package’s journey from the source to the package’s destination. The aspect of package theft also includes theft by…
Putting Big Data analytics to work Hello Adriaan Stander, Good post The procedures for the determination of the validity of the regression model comprises of comparing the model predictions as well as the coefficients using theory, data collection to check the predictions of the model. Outcome comparison with the theoretical calculations of the model, as well as splitting of data or cross-validating where part of the data is used in the estimation of the coefficients of the model, the remaining information is then utilized in the measurement of the prediction accuracy of the model. It is also notable that splitting of data is an effective procedure for model validation in an event where the collection of new data for purposes of model testing is not practical. An algorithm known as the Duplex algorithm which was developed by Kennard is a good recommendation for the division of data into the set of estimation as well as prediction set in case there is no visible variable like time for use as a basis for data splitting (Ludwig et al., 2015). …
Data Mining Use Cases and Business Analytics Applications Hello Cindy Odipo, Great content Regression models are frequently used for prediction, estimation, and estimation of parameters as well as control. It was evident that the person using the model is not its initial developer. Therefore it is always essential that before the model is released to the users, there is a need for some assessment as far as the validity of the model is concerned. There are two things, model adequacy as well as model validation. Model adequacy is an amalgamation of residual analysis, lack of fit testing, high-leverage or overly influential observations searching as well as some other internal investigation which investigate regression model fit to the present data. Model validation, on the other hand, focuses on the examination of it or not, the model shall function as desired in the intended analysis (Hofmann et al., 2013). It is therefore worth noting that a model which fits well the data, is also likely to be successful in its final application. Reference Hofmann, M. and Klinkenber, R. (2013) RapidMiner: Data…
