Implementation of Backup Domain Controller

Question: Discuss about theImplementation of Backup Domain Controller. Answer: Introduction A Domain Controller is a machine capable of answering the logon requirements or requests from a work station in Windows NT Domain. Every time a user logs into the Windows NT Workstation, the workstation gets connected to a Domain Controller then asks the user whether the password and the username typed is correct. The Domain Controller then replies with vast information about the user, for instance, the location of storage of the users information or profile and the full username of the user. SAM. There are two known kinds of Domain Controllers in an NT4 Compatible Domain. These include the Primary Domain Controller (PDC) and the Backup Domain Controller (BDC). The PDC has a master copy of the SAM. Whenever the SAM is to change at any feature at any given point, then the said change has to be made at the PDC. For instance, the intended change may be that of a password or username. Literature Review The choice on what entails the best path to cloud backup solely depends on a persons or companys workload, security requirements, demand, service level expectations among other important factors. The Microsoft Azure cloud, for instance, is a platform that offers a collection of integrated services, that is, computation, storage, data, apps development and networking, things that are known to not only add value to but also expand on the IT value of ones business without any forms of complexity. Windows Azure Pack gets integrated with Windows Server 2012 to offer the self-service portal for the management services like websites, scalable web hosting, and virtual machines among others [2]. Windows NT makes the use of an imaginary domain in managing the set of network resource meant for a set of users. This only calls for the user to log in and be able to gain access to the resources that are connected to the Domain controllers which can then be connected to one or more servers at a time. The primary domain controller is there to provide for or manage the master user-database for the domain. It sends copies of the database in a periodic manner to the backup domain controllers. The backup domain is then seen as a factor meant to key in regarding roles in place of the primary domain controller [4]. In a typical Windows NT, the given domain is known to combine some of the advantages of the workgroup and the directory. In this connection, the domain concept not only allows the user to gain access to varied domains at a time but also makes the user have resources from other trusted domains. Nonetheless, not all servers in Windows NT network require primary domain controllers to execute their mandates. With the recent installation of Windows 2012 R2 having both the R2 Domain Controllers and the Read Only Controllers, there will be the need for the deployment of strategic areas having a well defined redesigned network. For the small and medium-sized businesses, technology has taken a key role in shaping the whole integration of networks in a bid to improving efficiency and the connection with new customers as well as markets and used in the maintenance of the competitive edge. By any company aiming to upgrade to a new processor-based server that runs the Windows Server 2012 R2 operating system, there can be some breakthrough anticipated with performance, speed and flexibility of the business expected to be high and about. It is important to take note of the fact that modernizing the SMB with Windows Server 2012 R2 that runs with processor-based servers like Intel Xenon, speed, maximized performance, security and compliance are assured [6]. In actuality, a server that is based on Intel Xenon is preferably suitable for the modern business due to its deliverables concerning security and performance. Windows Server 2012 R2 server is known to provide many benefits such as reduction of costs on such things as IT maintenance, costs, and power bills. The server has a built-in virtualization that enables it to run some applications on the same server. This ultimately helps the user to obtain more out of the hardware invested[1]. It is not in doubt that leading solutions offer both secure, efficient and resilient IT foundation that is meant for the centralized data storage, offer powerful data protection and provide secure remote access. Windows server backup refers to a feature that offers a set of tools and other wizards for the user to perform the basic backup as well as recovery tasks for the server it is run on. The Windows Server finds useful practical application in offering backup to a full server having all volumes, and sometimes to those with selected volumes, specific files and or folders and lastly, to the system state. In such cases as hard disk failures, the user can perform bare metal recovery. In essence, it is possible to recover volumes, certain applications, folders and the entire original state of the system [3]. It should be noted that for this to be recovered; the user needs to have in place, back up to the full server or the volume containing the operating system files as well as the Windows Recovery Environment. If done, this will make sure that the system is completely restored back to the original state or into a new hard disk. In actuality, with Windows 2012 Server in place, it is possible to have the creation and management of local or remote computers. Moreover, it is possible to have a scheduled back up that runs automatically. Windows Server Backup is meant for any user who has the intention of making the basic back up the solution which often varies from small to large business enterprises. It is also important to note that the Windows 2012 Server Backup is not suited for persons who are not IT professionals as it involves very fundamental IT concepts to run. To improve the performance of any server backup, be it Windows 2008 R2, Windows Server 2012 R2, or Windows Server 2012, the use of the Optimize Backup Performance can prove useful as it not only improves the performance of the backups to the full volume but also improves the server performance. The prompt is available at the homepage of Windows Server Backup snap-in. it is important to note that these settings only apply if the user has included full or entire volume to be backed up. The settings will not apply in such cases as a file or a folder being backed up. Useful Steps in Adjusting the Performance Settings for Windows Server 2012 R2 Click Start Administrative ToolsWindows Server Backup Actions pane (in snap in default page),Windows Server BackupConfigure Performance SettingsOptimize Backup Performance dialog box. The Optimize Backup Performance pane has two options; the Normal backup performance and the faster backup performance. In the Normal backup performance, the backups created are full backups. In this regard, the Windows transfers the contents of the volume backed up. Essentially, the backed up space is only meant for the changed blocks on the server or source. The faster backup performance, on the other hand, specifies that the backup created is that of incremental backup. The windows then leave a shadow copy on the volume of the server used in tracking the changes. With the installation of Windows 2012 R2, bot the Domain Controllers and Read Only Domain Controllers will have the need to deploy the strategic areas of the redesigned network. Every IT professional who deals with the issues of Microsoft technologies are akin the Windows Server, but a couple of the professionals are not fully aware of the Essentials edition that is solely designed for the small scale businesses. In this brief, we are going to highlight some of the benefits and limitations that come with the Windows Server 2012 R2 Essentials. It was also incepting to highlight how best the server can be used to the advantage of the common small businesses like this scenario. Some of the notable benefits of the Windows 2012 server is the ease of deployment and its use. Coupled with low cost, this server allows the users to have the better experience of enjoying the essentials as well as focusing on the core business while minimizing on the maintenance of the IT infrastructure. The deployment of this server is meant to be easy. Notably, it is possible to install the Windows 2012 Server R2 Essentials on the 1.3 GHz processor or a 2.0 GHz although the most preferred processor would be a 3.0 GHz having the RAM of between 12- 16 GB [5]. The other advantage of employing a Windows 2012 server R2 is the possibility of cloud integration. Cloud computing is one such increasingly important entity in many organizations as part of the Information Technology strategies. It is not, however, what all companies fancy as not all of the organizations would prefer storing all information on the cloud, more so the highly sensitive information. To save this fear, a hybrid cloud has been put in place to quench some of these fears among organizations that feel a bit comfortable entrusting their sensitive data and critical applications to the public domains [6]. It should be noted that a true hybrid cloud may prove very technical and challenging to implement when it comes to the implementation and management of the same. This may be regarding budgetary costs for small business enterprises to manage. This cannot, however, mean that the small business enterprises cannot enjoy the comfort of storing their information on the cloud provider as well as enjoying the savings on the cost of the cloud computing and the security that comes therein. Aside from these privileges, the small businesses can have their privacy in so far as their critical data information is concerned. This is the sure reason for the designation of the Windows 2012 Server R2 Essentials. The small business network that is based on the Windows Server Essentials allows the user to run the applications and also store the files on the premises while at the same time, interoperating the seamlessly with the Microsoft Offices Office 365 cloud that is a hosted Exchange services as well as Windows Azure Backup for purposes of secure off-premises for the data storage. If properly implemented, the server can be helpful in providing the best of the both worlds. Windows Server 2012 R2 is that it offers remote access. With the high profile exceptions like Yahoo, for instance, companies of sizes are embracing the idea of remote access and telecommunicating. There are many studies that have shown that many of the workers who do either part-time or full-time jobs have demonstrated a sense of satisfaction, thanks to the remote access and telecommuting. More importantly, these workers are also known to enjoy their work and be more productive in their work. It is not in doubt that many companies have been bale to work without the brick and mortar kind of structures around them. Every Tom, Dick and Harry is comfortable working from the comfort of their homes or by the road side provided they have access to the server. This approach is of great importance to the organization since the efforts, money and the electricity bills, as well as rent that would otherwise be pumped into the structure, can be channeled back to the business to ensure that the bu siness is made more profitable in ways that can be deemed sustainable. For an organization to achieve the support of the remote workers, it is important that the business puts in place, access to the shared files that the employees may need to collaborate on the intended projects. Even if the company lack telecommuters, it is highly possible that high-level employees in the organization carry with them, work to homes and or while traveling and as such may require the use of files and applications necessary for them to perform a range of projects and tasks. Multitenant Security and Isolation The server virtualization tends to offer isolation between the virtual machines. The network layer, however, is never fully isolated and the second layer connectivity that tends to be more implied between the different workloads operating on the same infrastructure. The server virtualization provides a full isolated network of the datacenter via the programmatically run and managed extensible capabilities. This, in turn, enables the connection of the server to the network of the virtual machine in question and as such, brings forth an enhanced security and isolation of the policies. The private virtual local network that is otherwise known as LAN or PVLAN allows for the administrators of the Hyper-V to isolate the virtual machines from one another, for instance, the virtual machines can never contact fellow virtual machines over the same network while at the same time maintaining the external network connectivity for the same virtual machines. Put in other terms, and the LAN cannot achieve an increase in virtual machine isolation in the multitenant environment while at the same time grading the access to the public networks. It should be noted that the Network Virtualization Virtual LANs are meant for the isolation of networks but are in most cases very complex to handle, especially when it comes to managing large scale organizations and businesses. It is, therefore, useful to make use of the Hyper-V network virtualization that will ensure that the isolation of the networks in this sense is achieved on the network traffic, provided the shared infrastructure is available without the need to have the use of VLANs. The Hyper-V network also allows the users to move the virtual machines while at the same time ensuring that their network assignments are preserved. Notably, the network virtualization tends to eliminate the hierarchical IP addresses that are assigned to the virtual machines. It is also worth noting that a virtual machine can best be replaced by any node, the IP addresses notwithstanding, even if it means being across the cloud. More importantly, rewriting this feature in the Windows Server 2012 2R is not possible as each virtual machine is mapped to a unique host provider address known as PA. The Hyper-V network virtualization makes use of the IP address rewrite to have the mapping of the CA to the PA. The Hyper-V Virtual LANs are helpful as they make it possible to achieve the maximal performance of the new hardware which can be in form of servers, appliances or switches among others. In this regards, the VLANs eliminate the need to carry out an upgrade of new network adapters, appliances or the switches themselves. Conclusion Conclusively, computer databases are known to store records or files which can be customer profiles, employee profiles, product catalogs and sales transactions among others. A database manager is charged with the responsibility of ensuring that the capabilities of counting access or controlling the readings of the records are met, specifying the reports that are generated and analyzed in a single usage. These important records, if lost, can mean that the organization headed for a doomsday and as such, needs to resort to the cloud backup system. In actuality, if MNO is to increase the efficiency of its LAN by adding a backup domain controller (RODC/BDC), then the adoption of the cloud backup system coupled with the adoption of the Hyper-V LANs will prove essential so as to provide all the services in case of failure of the primary domain controller (RWDC/PDC).
