The primary purpose of this paper is to describe the architecture of a popular hypervisor as well as its benefits. The paper will focus on VMware ESXi Hypervisor Architecture. Typically, virtualization technology is the most efficient means to minimize IT expenses as well as boosting agility and effectiveness for all size business operations (Lu & Xu 2018). It is also an effective means of transforming data centers. Consequently, hypervisors are mainly used as an abstraction layer for isolating virtual machines from the system hardware. This enables the virtualization administrator to install the virtual machine without having to worry about device drivers for use in the hardware platform. Moreover, the hypervisor isolates one virtual machine from others (Azzam et al., 2019). In that regard, if a single virtual machine is having any challenges, it does not interfere with the functioning of other virtual machines.
VMware ESXi Hypervisor Architecture
Typically, this hypervisor is not only the next generation hypervisor but also an innovative architecture whose role is to provide a new basis for virtual infrastructureConsequently, it functions independently thereby offering increased reliability, simplified management, and improved security. Moreover, the compact architecture is perfectly designed for purposes of integration into enabling rapid installation, virtualization optimized server hardware, deployment, and configuration (Azzam et al., 2019). Consequently, VMware ESXi Hypervisor architecture brings along with it a management replica whose principal tenents include centralized management including policy and administration, interchangeable devices, and communication with the system utilizing well defined as well as standardized APIs.
Further, the architecture is composed of VMkernel and operations that run on top of it. They include; Direct Console User Interface; a management interface with low-level configuration which is accessible via the server’s console. It is utilized for preliminary configuration. Virtual machine monitor, an operation that primarily provides the implementation environment for a virtual machine. Also, various agents enable high-level VMware Infrastructure management from outlying uses. Lastly, the Common Information Model (CIM) system which is an interface that enables the hardware-level management from remote applications through a set of APIs (Azzam et al., 2019). More importantly, the underlying OS provides a means for running every process in the system such as agents, virtual machines as well as management applications. Besides, it has total control of every hardware device present on the server. It also runs all supplies for the applications.
Benefits
The ESXi architecture has numerous advantages as compared to other virtualization platforms. First, it has little state information whereby it can be treated for pragmatic purposes as stateless compute mode in which all the data is uploaded with ease from a saved file. The second advantage is its battery security. In that regard, an ESXi system posses a small footprint as well as minimal interfaces and as a result, has a lower attack surface. Thirdly, it has Hardware-like reliability (Azzam et al., 2019). Typically, following integration into the firmware, the software is less likely to be corrupted mainly when stored on disk. Moreover, the alternative of getting rid of the local disk drive can yield greater system reliability.
Conclusion
Overall, the capacity to deliver infrastructure services to numerous external clients is a vital element of every service provider’s business. VMware ESXi Hypervisor provides numerous opportunities for every service provider to deliver perfect and dedicated services to several tenants.Again, by [roviding numerous trusted multitenancy options, every service provider can address major issues of his clients in a multitenant environment: security, compliance, data protection, confidentiality, and management control. Moreover, any conversation regarding virtualization for either small or medium-sized businesses typically starts around VMware which offers various solutions to their wide variety of needs. Lastly, the virtualization technique is not only easy to use but also posses robust security features that are behind its reputation as the best alternative for virtualization at small and medium-sized businesses.
