Discuss the benefits of virtualization software.

The term virtualization is used for the application of the software in creating abstraction layers that will exist over the physical hardware. Virtualization allows users to run various virtual computers, applications, and OS, among others, on a single physical server. Virtualization has the capability of bringing in a lot of benefits to the users. Among them is the ability to slash the expenses, and there are a lot of inefficiencies when using the non-virtualized environment since one is not fully making use of applications on the servers. It cuts down the IT cost by enabling a single physical server to run from various virtual machines with different OS and running different applications when still hosted by one server (Menken & Blokdijk, 2018). Another benefit is the ability to reduce downtime and enhance resiliency during disaster recovery. Whenever a disaster strikes, it becomes important that an individual is tasked with fixing and replacing the affected physical server. The virtualized environment makes it possible to deploy, and one can easily clone or replicate the Virtual machine affected. Time taken to recover from a disaster with the virtual machine fully is normally short compared to the time taken to replace the damaged physical server with a new one fully. This allows the users to enjoy elements of resiliency and continuity (Rot & Chrobak, 2018). Another benefit is the ability and the chance to increase productivity and efficiency. Improved productivity and efficiency are curtesy of having few servers. It helps the teams involved in IT to be able to spend a short duration when maintaining the IT infrastructure and physical hardware (Khelf & Ghoualmi-Zine, 2018). The virtual environment will assist and play a crucial role in allowing one to install, maintain and update everything across the virtual machine. One does not necessarily have to go through a tedious and rigorous procedure in updating each server. It is another benefit brought about by virtualization where it is possible to offer control to the dependence and also the DevOps. It is easy to spin up a VM without affecting the production environment. It makes it easy for eh developer to clone the virtual machine and run the tests on the current environment (Rot & Chrobak, 2018). Another vital benefit is the ability to conserve the environment by using less power due to the fewer physical servers in use. These benefits assist in cost reduction and hence a chance to reinvest the money and secondly a chance to reduce the carbon footprint for the data center.

Do you agree/disagree with these benefits?

The above benefits mentioned, which have been proven to be true by the experts and supported by the many types of research done, I agree with the benefits mentioned above.

Discuss the security concerns highlighted by server sprawl and how you would propose to solve those in your (real or hypothetical) organization.

There are concerns in matters of security when it comes to server sprawl. Security is a major concern since the information stored is always guided by the principles of information, calling for integrity, availability, and confidentiality to be observed at the highest levels. The cloud providers must at all times assure and guarantee security by being able to approve the authorized identity before granting access and also deny the Imposters. Data transmission via clouds must also be protected, and again the information of clients must be separated from others (Khelf & Ghoualmi-Zine, 2018). To get the solution to that challenge is to adopt new ways of authenticating the real and actual users of eh information before granting access. It can be a two-way or biometric authentication where an individual will be examined on the physical characteristics and matched with the information in the servers before being granted access (Menken & Blokdijk, 2018). Another solution is to bring on competent board employees knowledgeable in maters security to ensure that they work well and have the resources they need at their disposal.
