Command-Line Tools The following command-line tools are popularly used for system services and applications.•Is-up-cli: It is an open source tool that allows provides the ability to the users to checkthe website status in a seamless manner. Only a single command is used to checkwhether the website is up or not. It also has a separate library that is used to tap into theAPI. •Pageres-cli: It is a tool which is used to capture 100 screenshots from 10 differentwebsites in less than a minute. The screenshots that are captured can then be used forwork purpose. The tool can also capture different resolutions from different sources. •Surge: It is a command-line tool that is required by the developers for publishing of thewebsites and web content comprising of HTML, CSS and JavaScript on web. A completefolder can be published with a single command using this tool (Stackify, 2017). •Loadtest: It is necessary to check the performance of a website so that the customerexpectations and requirements are fulfilled. Loadtest is a tool that performs load testingof a website and also allows an option of custom configuration. In-depth server testing isalso carried out using this tool. •Caniuse-cmd: This is a tool which is used to check for the errors and mistakes in awebsite to maintain the workflow. The availability of the features is also checkedthrough the aid of different browsers. •Moro: This is a tool which is used to check and track the amount of time that is requiredfor the execution of a particular project. Tracking of the entire data sets is done fordetailed reports. Hardware Components of a Server•Motherboard: This is the main hardware component of a server which is used forconnecting the different elements and components of a computer. There are various built-in features of a motherboard that are present called graphics adapter, network interfaceetc. In case of failure of a motherboard, the functioning of the entire server may get

impacted. This is the reason that the motherboard shall be checked in case of the serverfailure. •Processor/CPU: The processor is the main component of the computer system and server.It is one of the major components that impacts the system performance and behavior.Clock speed and processor cores of the processor are concerned with the processor. Incase of server failure, the processor/CPU shall be checked and verified so that systemperformance can be measured. •Hard Drive: There are a number of IDE drives that are connected with the computersystems. For the individual users, these drives are adequate. However, SCSI drive is usedfor high performance and control. Reliability and performance of the systems and serversare based upon hard drives (Dummies, 2017). •Memory: There are many different types of memory that are present and are involved inthe computer systems and servers. There are a number of servers that are present whichcan support memory capacity of 32GB. There can be failures that may take place in caseof memory that may impact the server performance and failure as well. •Network Connections: There are numerous network connections and equipment that isconnected to the system and server for its functioning. In case of server failure, it ispossible that the networking equipment is faulty. Main Features of Windows Server 2012•New Server Manager: This is the feature of Windows Server 2012 that allows thecapability for the creation of the server groups. These server groups are the collection ofdifferent servers which can be easily managed and can provide enhanced user experience.There is an enhanced management of task and every server has a certain set of commonattributes. The companies and organizations that do not have dedicated monitoringpackages and software in place can make good use of this feature. •Command-Line First, GUI Second: The previous versions of Windows Server came withan option to install the GUI first. However, in case of Windows Server 2012, the primarycapability has been provided to install the core services and server. With this option, theGUI role can be used and installed after the installation of the server. With this manner,there are various advantages that are provided in terms of reduction of the attack surface,resource load and energy (Hassell, 2012). •Enhanced storage space: The storage space that is involved and present in the case of

Windows Server 2012 makes use of inexpensive drivers and controllers. There is a poolof storage that is involved which is then classified in different sections which can be usedlike regular disks. There is a lot of scalability and flexibility that is associated with thestorage space that is used in this case (Brown, 2012). •Dynamic Access Control: It is necessary to manage the data and information sets in acorrect and accurate manner. Dynamic Access Control (DAC) is a feature that is presentin the case of Windows Server 2012 which can enhance access control in the case ofinformation sets. There are limited and minimal additions and enhancements that aremade to the Active Directory. This feature provides the strong capability and abilities tomanage the file systems with enhanced security and control (Savill, 2013). •Resilient File System: New Technology File Systems (NTFS) was earlier used in case ofcomputer servers and systems. Resilient File System (RFS) is an enhancement of NTFSfor providing the properties and abilities as availability and integrity. There is a use ofchecksums and real-time allocations for the protection of sequencing and access of all theinformation and data sets. In case of occurrence of an issue or a problem that is identifiedin case of Windows Server 2012, there can be automatic repairs that can be made withouthaving any impact on the availability of the data and information (James, 2012). Capacity Planning Strategy for Cloud VirtualizationCapacity planning strategy includes the mechanisms and measures that must be included for theplanning of capacity for satisfying the demand that is associated with the products and servicesover a specific period of time. Strategy ScopeThe capacity planning strategy that is necessary and is required to be developed for cloudvirtualization must be ongoing. It is necessary to make sure that detailed inventory regarding theavailable space and application running on a particular infrastructure are maintained (Metron-athene, 2017). In the case of capacity planning strategy for cloud virtualization, the set of services that will beprovided by a particular environment shall be determined. The deployment of enough storageshall be done as a next step in order to fit the size of the environment (Tang, 2017). Steps to FollowThere are various adjustments and steps that need to be followed for the creation of the capacityplanning strategy for cloud virtualization.
