Managing Virtual Machines

150+ word reply to the following: Managing virtual machines There is a lot more to virtual machines besides just installing them. They do require a good deal of managing. A few of the management requirements are adding and registering virtual machines, changing power states, and removing or deleting virtual machines. While some virtual machines can be created from scratch in the system you can also get pre-created virtual machines. The problem with the pre-created VM’s is that you are required to put a registration code. Registering a VM allows it to be accessed in the vCenter Server. Registering a virtual machine is important because it allows you to see performance metrics and the storage system. Power states are very important when managing virtual machines. There are 4 initial power states as well as 2 additional guest power states power on/off, suspend, reset, shut down guest, and restart guest. Power on/off and reset are standard. Suspend allows you to close the machine and start it back up at a later date right where you left off. The guest power states are only available with VMware Tools. Sometimes removing or deleting a virtual machine will be needed. Although it seems similar the 2 actions actually entail different things. Removing a virtual machine means you want to keep the VM but don’t necessarily need it listed in the inventory. Removing it allows you to keep the files while removing it from the inventory list. To re-add the removed VM you simply follow the regular adding or registering process. Deleting a VM is when the entirety of the virtual machine is no longer needed. It won’t be listed in the inventory and it won’t keep your files in the datastore. Unlike removing a VM, deleting is permanent. While there are other ways to manage a virtual machine, such as modifying them, these are among the simple but important ones.

Data Mining Applications in Business and Analytics

In this project, you will be expected to do a comprehensive literature search and survey, select and study a specific topic in one subject area of data mining and its applications in business intelligence and analytics (BIA), and write a research paper on the selected topic by yourself. The research paper you are required to write can be a detailed comprehensive study on some specific topic or the original research work that will have been done by yourself. Requirements and Instructions for the Research Paper: 1. The objective of the paper should be very clear about subject, scope, domain, and the goals to be achieved. 2. The paper should address the important advanced and critical issues in a specific area of data mining and its applications in business intelligence and analytics. Your research paper should emphasize not only breadth of coverage, but also depth of coverage in the specific area. 3. The research paper should give the measurable conclusions and future research directions (this is your contribution). 4. It might be beneficial to review or browse through about 15 to 20 relevant technical articles before you make decision on the topic of the research project. 5. The research paper can be: a. Literature review papers on data mining techniques and their applications for business intelligence and analytics. b. Study and examination of data mining techniques in depth with technical details. c. Applied research that applies a data mining method to solve a real world application in terms of the domain of BIA. 6. The research paper should reflect the quality at certain academic research level. 7. The paper should be about at least 3000-3500 words double space. 8. The paper should include adequate abstraction or introduction, and reference list. 9. Please write the paper in your words and statements, and please give the names of references, citations, and resources of reference materials if you want to use the statements from other reference articles. 10. From the systematic study point of view, you may want to read a list of technical papers from relevant magazines, journals, conference proceedings and theses in the area of the topic you choose.
