Data protection by making backup copies of data (backups) is a critical element of any IT system. Backup copies of data is crucial for ensuring survival of the company, and sometimes permanent loss of even a small amount of data can be fatal for the operations. The scale of the financial and reputational damages suffered by the company will depend on the speed with which the IT system, and thus the working processes will be restored after the disaster.

A back up copy of data, and sample procedure for returning them is crucial in cases where it is necessary of disaster recovery. Whether it is for a partial loss of data of minor importance or corruption of a large amount of crucial data, how successful and how quickly we can recover normal operation of the company depends on the software for backup & restore that it is used.

How will the system look for making safety copies depends on:

• Acceptable loss of data and transactions (RPO -Recovery Point Objective)
• Acceptable time without data and production (RTO -Recovery Time Objective)

Virtualization of the servers bring new and advanced features for making backup and recovery of data, so that for virtual environments there are specialized backup & restore solutions that utilize all the advantages of virtual environment in order to ensure Business Continuity.

Component part of the process of making a backup copy of the data represent inspected and restore procedures that ensure the integrity of the work of backup or verify that the default values for the parameters RPO and RTO are achieved.

Benefits:

• Data lost protection
• Quick establishment of system functioning after crush

Properly sized and quality performed network infrastructure is a cornerstone in the successful operation of any company. Depending on the size of the company, and its specific requirements, each company chooses the optimal network solution. The service for the implementation of network infrastructure includes initial sizing of the system according to the needs and requirements, installation of equipment and maintenance of the system is after putting into operation.

Network infrastructure can be divided into LAN and WLAN (wireless) networks. Except that it represent basis of any IT infrastructure, LAN networks are increasing employee productivity and competitiveness of the company in a way that enables implementation of new applications and services such as voice and video.

For the critical parts of the system it is required a highly reliable LAN and WAN architecture that meets the strict requirements of transfer and security.

WLAN networks are a popular solution for data transfer and voice. The implementation includes analysis of the area that has to be covered by a wireless network (control of free channels, analyzing the radius of coverage of antennas and obstacles in communications), implementation and configuration of Access Points, implementation of wireless controllers for monitoring and control of AP’s, separating the access for gests from the one for employees etc.

Network communication solutions include switches, routers, wireless devices and security solutions for networks.

With the increasing number of applications and systems used in organizations, alongside with increasing the number of identities that employees will use, the IT team must manage. In fact, one of the main challenges of IT management is the authentication, authorization and rationalization of identities (users, computers, etc.) Because there is a big need for a central place where you keep information about users and their privileges.

Microsoft Active Directory is the most famous Directory Service that is included as part of Windows Server products and which among other things allows you to:

• Creating a Unified Directory architecture;
• Implementation of Active Directory domain controllers and replication architecture according to the needs of the organization;
• Implementation of a number of business applications;

Microsoft Active Directory solution will reduce system complexity, simplify management and enables easier integration of new technologies, which will result in lower costs, higher productivity and agility.

Creating unified directory architecture

Active Directory domain allows unified directory for authentication of users across the organization. Among other things, unified Active Directory architecture includes:

• Organizational model units and delegation
• Group policies and preferences
• Strategy of security groups
• Passwords policy

Implementation of Active Directory domain controllers and replication architecture

Consolidation of the Active Directory design of domain controllers and architecture for replication will allow the most effective physical access to the directory, taking as a factor network and data center into consideration.

Implementation of a number of business applications

Microsoft Active Directory infrastructure is a precondition for implementation of a number of business applications services such as Microsoft Exchange Server, Microsoft Sharepoint Server, PKI (Public Key Infrastructure) etc.

Benefits:

• Centralized management of identities of users, computers etc.
• Access control and privileges to resources on the network.
• Basis for the implementation of many popular business applications and solutions.

Servers virtualization

Servers virtualization allows optimized use of hardware resources, consolidation of existing servers or fast and efficient implementation of new services with flexible assignment of hardware Resources of virtual servers, increased stability of the system or simply achieving high availability of services, even for applications that don’t know how to work in a cluster.

Virtualization of servers and opens doors for very fast recovery in case of a problem with the server concerning cheap repair scenarios in the event of a disaster. Significantly easier migration to new servers or systems for providing data.

Virtualization allows procurement and maintenance of a smaller number of servers, which appropriately requires less space in ruck units, and from there less cooling and less electricity, and all this leads to significantly more efficient and economical system.

Servers virtualization is a cornerstone of Cloud computing.

Desktop Virtualization/VDI (Virtual Desktop Infrastructure)

With the virtualization of desktops there is separation of client operating system from the clients hardware, and the user keeps the same desktop regardless of which device he will use and where it connect to.

For virtualization of desktops there are used server resources, while the performance of client PCs accessing virtual desktops become insignificant, so it can be replaced by cheaper and more practical thin or zero clients, tablets and so on. User data while remaining the server infrastructure which ensures system reliability.

Virtualization of desktops enables:

• Centralized management of desktops;
• Consolidation and optimization of desktops;
• Simply upgrading the client operating systems;
• Raising various safety systems;

VDI solve the problems of diversity and age of the client computers in companies, so that enables the use of new operating systems on older computers.

Virtualization of desktops allows much greater accessibility to computers of end users, because in case of a breakdown of the devices, it can simply make a replacement with another without the need for reinstalling the operating system, applications and user data copying.

Depending on the needs and opportunities, it chooses the technology that will be used for desktop virtualization -VDI (Virtual Desktop Infrastructure) or virtualized presentation (remote desktop).

Applications Virtualization

Virtualization of applications represents creating of a packaged applications that run in their own, so called, balloon and it will be no interaction with other applications on the system level.

Virtual application does not install, respectively its package is only distributed to the client computer. Virtual applications are running on the client computer, and can be executed without having access to the network.

Application virtualization solves the problem of simultaneous execution of mutually incompatible applications on a computer, accelerates and simplifies distribution and installation of the application on a user's computer, accelerates application upgrade and replace computers at brake down.

Benefits:

• Savings for efficient use of IT resources and energy
• Secured Business Continuity
• Rapid adjustment to emerging needs
