Platform Benefits
flexible scaling and excellent performance
If necessary, you can increase productivity and other resources. Add power for the time you need, and then go back. Thus, you will not pay for that performance and unnecessary technical specifications that you don't use.
The platform is based on multi-core processors Intel Xeon 7300 series. As a storage platform, you can choose a system based on shared network storage (SAN FC), which will provide you with excellent data access speed and extraordinary reliability, or a cheaper, but very reliable system based on high-performance Raid controllers Adaptec (HDD RAID).

You probably noticed that recently it has become popular to transfer company servers to a virtual environment, and in this video I propose to consider such a virtualization option as VPS and VDS virtual server.
In fact, VDS (Virtual Dedicated Server) and VPS ( Virtual Private Server) is the same concept and denotes a virtual dedicated server.
The principle of creating a virtual server is as follows.
Running on the physical server operating system, which helps to create these very virtual servers, which is called a hypervisor. It allows you to completely isolate virtual servers from each other. Thus, the operation of one VPS cannot affect the operation of other servers, they cannot access files or network packets and the contents of each other's RAM. As a result, any number of virtual servers can be created on one physical machine, as far as the hardware allows. Each such server will have its own operating system and settings. Thus, it will appear that you are working on a physical server, but you are connecting to it remotely.
You can implement this virtualization system either on your physical server or using a cloud service.
Benefits of moving to the cloud:
Cost optimization. No need to spend money on the purchase and placement of expensive equipment. Since renting a VPS allows you to avoid large one-time costs.
Saving on resources. According to statistics, the resources of own equipment are rarely used by more than 50%. At the same time, a virtual server can be created exactly with the parameters that are needed today. You can adjust the number of cores, disk capacity and RAM, so as not to pay for redundant configuration.
operational organization of work. You will spend from a week to a month to buy and install your server. The choice of equipment, payment, delivery, connection, configuration - it all takes a lot of time. When creating a virtual server, you only need 5 minutes and the VPS, with the desired configuration, is ready to go.
Easy scaling of resources - you can increase or decrease VPS parameters in just a couple of minutes. You pay only for the resources you need here and now.
Reliable storage of information. Since the data is stored in a mirror Raid array, the information is duplicated on two independent media, and if one of them fails, your data will not be lost.
ROOT access. You are provided with full administrators to manage your VPS. You can install any software, operating systems and change any settings.
Flaws:
The need for a constant stable Internet connection, since when the Internet is turned off, all work will be paralyzed.
Subscription fee - every month you have to pay subscription fee for equipment rental. But, here it is up to you to decide whether this is more of an advantage or disadvantage, since the configurations can be different, and hence the cost of subscription services.
As part of this video, we will just create a virtual server through a cloud service
As you can see, on home page service, you are immediately given the opportunity to specify the server characteristics you need through the configurator. Thanks to this, you can immediately see how much it will cost to rent this server per month or per day.
You can also test the operation of a virtual server for free, for this it is enough to leave a request to connect a test virtual server. As you can see, the test period is quite short, for individuals 1 day, for legal 3 days. However, the developers went to meet me and are ready to provide 5 days for my subscribers free testing. To do this, you just need to inform the manager, who will call you back after sending the application, that you are a subscriber of the "IT Training Center"
Well, now let's see how it all works.
We enter the site under our registration data. At the top of the site, you can see how much money you have in your account. If you are working in test mode, then you will be provided with a server with certain settings, but I will not consider the test, but the operation of the service in full mode.
Virtual private server configurationVPS (VDS).
In your personal account, go to the section Virtual servers \ Create new \ Server name \ FTP server.
Templates - I'm interested Windows Server 2016 R2. Next, we choose desired configuration iron, it is worth noting that for different configurations, the cost of rent will change, so choose the best option for yourself, taking into account performance and cost of rent.
The number of cores, the amount of RAM, HDD space and hardware, everything is clear with this.
Shared (non-guaranteed) 100 MB/s - Provided here maximum speed the Internet channel is 100 Mb / s, but it will be distributed among several servers, therefore, if the Internet channel is loaded, then it is not guaranteed that you will get a speed of 100 Mb / s.
Dedicated 10, 50, 100 Mb/s guarantees that you will receive this Internet connection speed, as a dedicated Internet channel will be created for you.
Backup– daily backup server data
Additional IP - if you want to connect an additional network card with an external IP address.
Private the local network – allows you to organize a network between servers without access to the Internet, using internal IP addresses. At the same time, traffic is completely isolated from other users.
Extended SLA - Extended Warranty. NeoServer not only promises 99.99% virtual server availability, but also pays 10 times the downtime.
In any case, in the course of work, we will be able to change these settings if the need arises.
Next, click the "Purchase" button. Despite the fact that I have less money in my account than the cost of the server I assembled, I can still buy it, since this cost is per month. In the process of working with a virtual server, the cost of renting it will be charged not once a month, but every day, i.e. the total cost of the server divided by 30, this will be the rental price for each day of use. And since I have enough money to pay for one day of server rent, I can buy it J
The process of creating a virtual dedicated server has begun.
After creating the VPS, we have options for connecting to the server, via the web console or via RDP remote desktop.
It should be noted that the presence of a web console is a very important factor when choosing a VPS. It will allow you to connect to the server via Personal Area, even if the OS hangs or if due to incorrect network settings VPS became unavailable.
There is also a snapshot feature. It is recommended that you take a snapshot of the state before making any significant changes to the server. So that in case of negative consequences, you can return to the moment the snapshot was created.
We connect to a virtual server and see that it is no different from a real physical machine, with the same characteristics that we specified at the stage of creating a virtual server.
I'm not very happy with slowing down the server, so I'll add another gigabyte of RAM to more comfortably demonstrate the practical part of setting up the server (Turn off VPS server \ RAM 2 GB \ Save \ Enable VPS).
Now let's set up our server as an FTP server to see how a virtual server can be used in a real situation.
I will not go into the details of the FTP technology itself, as I plan to make a separate video on this topic, so I will configure everything as quickly as possible (Server Manager \ Manage \ Add roles and features \ Next \ Install roles and features \ Select our server \ Next \ Web server IIS\Next\Next\FTP Server \ Next \ Install \ Close).
Create a user to access FTP server (Tools\Computer Management\ Local Users\ Users \ RMB \ New user \User12345)
Create a folder for FTP access(C:\inetpub\ftproot\TestFTP)
Setting up FTP access Server Manager\Tools\Service ManagerIIS \ Sites \ AddFTP Site \ Name \ Path \ WithoutSSL\Next\Authentication\Basic\Specified Users\User12345\Read\Done)
Connecting ( Conductor \ftp://address server \ Enter username and password)
As a rule, there are several ways to save on renting a virtual dedicated server. The most common of them is the choice of the “without administration” tariff, when the purchased cheap VPS under Windows will be serviced only by you, however, for this you will have to study the virtual server settings yourself.
description of selected options
Windows- the most recognizable operating system today. Its popularity is due not only to its high prevalence on ordinary computers, but also on servers. True, in the second case, Windows is inferior in percentage terms. linux and FreeBSD taken together. The popularity of Windows on servers and VPS is primarily due to the interface familiar to most users. The classic explorer, start and other controls have long become familiar to everyone who is not alien to the computer. If you have always used only Windows, then to solve your WEB tasks you should order VPS with this OS.
Operating system security level Windows Server can be called low big number identified bugs and security fixes plus thousands malware like viruses and spies are not a bit of consolation. But everything is relative - a competent setting of all security policies will save you from 90% of the risks, because neither FreeBSD nor Linux have a significant advantage over Windows in terms of security: a lot depends on the skills of the VPS owner.
The possibilities of Windows on servers are almost limitless. This OS is capable of solving any tasks: creating a print server, DNS, files, Email, FTP and so on. Windows will perfectly cope with the implementation of any WEB-projects. The main advantage of Windows is the directory service. Active Directory. It is thanks to this feature that the operating system from Microsoft is in demand on servers. With it, you can add, remove, and move a wide variety of resources, manage your network, and perform many other tasks.
Windows Server 2016 is a cloud-ready operating system. Designed for high-load servers and ready for a quick transition to the cloud. The main improvements over Windows Server 2012 are security, business continuity in critical situations and when deploying new solutions, a focus on virtualization, applications and services.
Safety. Windows Server 2016 is released with built-in protection against network attacks aimed at capturing data and disrupting business processes. Protection consists in countering the attack as a whole (destruction of attack tools) and localizing the intrusion of intruders (preventing the spread of the attack). Strengthened protection against Pass-the-Hash/Pass-the-Ticket attacks, in which the attacker gains privileges or server administrator credentials. Device Guard controls the launch of only trusted software on the server. Windows Defender, Device Guard and Control Flow Guard are built-in components to prevent malware from running and installing on the server.
The security of virtual machines has been fundamentally changed. It uses shielded virtual machines (Shielded Virtual Machines) based on the second generation of VMs with support for Unified Extensible Firmware Interface (UEFI), which are encrypted using BitLocker. If an attacker gets access to a virtual machine file (from a backup or over the network), then it can only be launched on trusted hosts. Together with Host Guardian Service, this is a new level of security for virtual machines.
cloud-ready. Windows Server 2016 is positioned as a cloud-ready server OS, i.e. designed specifically to work on a remote server. Nano Server mode created for clouds and data centers, which can be selected during the process Windows installation Server 2016, it is optimized to run as a lightweight operating system (25 times smaller than a regular server). The Hyper-V hypervisor that was introduced in Windows Server 2012 has been improved, it uses the Azure data center, it quickly migrates from the local station to the cloud. Hyper-V has begun supporting nested virtualization for deploying complex infrastructures.
Administration and network. PowerShell 5.0 Server Management Shell in Windows Server 2016 has the ability to develop using classes, faster script execution, and improved security. Added PowerShell Direct feature for easier connection to virtual machines bypassing network interfaces.
Enhanced Active Directory capabilities. Added access control and single sign-on across many applications, such as Office 365, SaaS applications, and more. Active Directory 2016 has three new passwordless sign-in options built in: Azure Multi-Factor Authentication - MFA, access from compatible trusted devices, Microsoft Passport - user gesture authentication. Simplified AD migration from earlier versions to AD 2016.
The new storage technology Storage Spaces Direct is designed to organize data storage at a lower cost (saving up to 90%) than using SAN or NAS, has synchronous Storage Replica for disaster recovery without interruption.
A new feature is the sequential upgrade of the cluster operating system. An OS upgrade from Windows Server 2012 R2 to Windows Server 2016 occurs without interruption to the virtual or physical machine.
TCP Fast Open (TFO) reduces TCP connection time. Together with the increased ICW value, this is the ability to transmit large data packets in a short time, for example, from a client remote server. The mechanism for retransmission of lost packets has been improved (Tail Loss Probe (TLP) and Recent Acknowledgment (RACK) functions).
In Windows Server 2016, the telnet interface has completely stopped working.
Development. New in Windows Server 2016 is the container service. A container is an environment for the development and operation of an application that does not affect the surrounding virtual environment. Unlike conventional virtualization, operating system emulation is not required here, the container is deployed within one minute and is easily scalable. To do this, Windows Server 2016 uses Azure Container Service, and also supports Marathon, DC/OS, Docker Swarm, and Kubernetes.
IIS 10 supports the HTTP/2 protocol, requests for which are automatically handled by the web server. IIS 10 can run on Nano Server as well. Created to manage the web server new module IIS Administration.
Windows Server 2012 R2 Standard
Windows Server 2012 R2 includes everything necessary services for virtualization, remote administration, cloud network infrastructure, remote access and information protection, development platforms. Windows Server 2012 R2 offers a multi-tenant data center that simplifies the deployment of IT services. Windows Server 2012 R2 is in line with the Windows 8 client operating system.
Implemented new IP address management policy"IP address management", designed to manage and monitor DNS and DHCP protocol, fully supporting IPv4 and IPv6 Internet protocols.
A large number of changes have been implemented in Active Directory. Among them is the introduction GUI in the Active Directory Recycle Bin, more complex password policies, secure cloning of virtual domain controllers, easier migration to this version from previous versions, elimination of the need to download Active Directory Federation Services when installing as a role, since these services are included in Kerberos, etc.
Presented a new version virtual machine Hyper-V with numerous innovations, including network virtualization, cross-platform, cloud backup, etc. In addition, the previous restrictions on resource consumption have been eliminated. Each virtual machine in this version of Hyper-V can connect up to 64 processors, up to 1 TB of memory, and up to 64 TB of virtual disk space for 1 HDD(using the new .vhdx format).
Created and introduced a new file system Resilient File System(ReFS), originally designed for file servers as advanced NTFS. This file system includes great amount innovations and functional improvements, including the use of B + trees to ensure the reliability of disk structures, support maximum size file in 16 EB (106 TB), 18.4 × 1018 number of folders and a maximum amount of space 1 IB (1012 TB) due to 64-bit file specifications. File and folder names are limited to 32 KB of text. Most of the properties of the NTFS file system are inherited from ReFS. However, there are a number of unsupported options such as file compression, EFS file encryption, named file streams, hard links, and some others.
New version released Internet Information Services(IIS 8.5) containing properties such as SNI (an extension to the TLS protocol where the client reports the name of the host to connect to), centralized management SSL certificates, WebSocket with NUMA support, etc.
Technology created and implemented Storage Spaces, inherited from Logical Disk Manager (LDM), allowing organization hard drives through logical structures. In other words, a collection of hard drives of various sizes and specifications can be connected to a single pool, and the connection / disconnection of disks is automated and can be controlled by PowerShell commands. Each such pool supports file system ReFS and is limited to 4 PB (4096 TB), but there is no limit to the total number of pools.
Many changes have affected information security in various areas (access control, AppLocker, BitLocker, credential storage, group managed Accounts services, Kerberos, policy settings on local computer and etc.).
Among restrictions Windows Server 2012 R2 Standard should take into account the memory limit of 4 TB, the limit of processors in the system is 64 processors, the limit of virtual machines is 2 machines. Unlimited use of Remote Desktop Services, File Services, Network Policy and Access Services, and unlimited number of users on the system.
Among the main available services Windows Server 2012 R2 Standard can be noted DHCP service, DNS server, Windows Server Update Services, Hyper-V, ServerCore mode, Active Directory Federation Services, Active Directory Domain Services, etc. Also, Office 365 support is integrated into Windows Server 2012 R2, Windows PowerShell 4, Internet Explorer 11, .NET Framework 4.5.
Windows Server 2012 R2 Standard can be installed on virtual machine , and can also contain 2 virtual machines.
As a rule, there are several ways to save on renting a virtual dedicated server. The most common of them is the choice of the “without administration” tariff, when the purchased cheap VPS under Windows will be serviced only by you, however, for this you will have to study the virtual server settings yourself.
