VIRTUALIZATION IN ICT

The term "virtualization" is one of the most commonly used terms and appears in all areas of today's ICT.

We focus primarily on the most common area, virtualization of Data Centers equipment - servers, networks, data storages.

The main benefits of virtualization

Consolidation and optimization

Virtualization is a way to optimize your entire infrastructure effectively. It covers all areas of information technology and most components of today's data centre.

It allows you to consolidate and optimize resources and significantly reduce operating and investment costs in various ICT areas.

Benefits of virtualization solutions

  • more efficient use of computing resources by hardware consolidation,
  • flexibility of resource management (dynamic allocation, removal of resources),
  • energy and cooling savings,
  • centralized administration,
  • simplification of migration and backup-restore processes, disaster recovery,
  • higher availability of services.

Possibility for every company

The use of virtualization tools has become standard for large enterprises, but the benefits of deploying virtualization solutions are also appreciated by small and medium-sized enterprises (SMEs).

Our company will acquaint you with the possibilities of individual platforms, evaluate the benefits of use in your company, and develop a solution proposal.

Server virtualization

Increasing operational efficiency

In the form of the consolidation of server infrastructure, making better use of HW resources, and process automation.

Increasing operational security through support for DR processes, ensuring the high availability of tools for moving VM and integrated tools for creating VM clones, backups, snapshots, etc.

Centralized administration, supervision, and access to applications ensure greater work flexibility and more complex operational control in the virtualized environment.

Server virtualization properties

Virtual machines (VM) with various OS run on a hypervisor and are independent of server HW.

Individual VMs can be dynamically changed by assigning HW resources according to the operational needs of applications, can be moved to other physical servers without interrupting operations, or can be replicated into another Data Centre or Cloud.

The platforms enable new virtual machines and applications to be rapidly deployed and testing and development environments to be quickly built, including the use of effective backup scenarios.

We offer solutions

We implement solutions using the two most widespread platforms,

VMware vSphere® & Microsoft Hyper-V®, including their advanced features for increasing HA availability, security, replication, and backup, or tools for migration purposes, etc.

Thanks to our many years of experience in server virtualization, we are able to offer comprehensive services – needs analysis for companies, drafting a suitable solution, and selecting technology with regard to CTO, complete implementation, training, and our 24/7 Support and Service.  

Storage virtualization

Software Defined Storage (SDS)

SDS is changing the concept of data storage, which is seen as a service independent of particular hardware.

SDS solution, virtualization layer, can be created at the level of appliances or servers (running OS and special SW), where all available data sources (various HW disk arrays) are combined, which control the storage of virtual machine data using defined policies.

Such a solution then enables various ways of accelerating disk operations using FLASH technologies, automatic tiering, parametrization of the behaviour of data source functionalities - replication, backup, snapshot, deduplication, and compression.

 

The Software Defined Storage solution does not have to be created only from data sources in the form of HW disk arrays of various manufacturers.

To create a virtualization layer, you can use software that is installed on commodity x86 servers, which provides data mediation and management of the physical disk layer (internal disk capacity) of various servers.

The result is a high availability solution with N+X redundancy and a high-performance server and disk subsystem infrastructure with resistance to any HW outage within a single data centre (DC), as well as an outage of the entire DC in a multi-site solution.

 

We offer solutions

VMware® vSAN - a natively developed platform for virtualized environments that, together with VMware vSphere, forms a state-of-the-art hyperconverged infrastructure (HCI) solution.

SDS supports a wide range of workloads, including artificial intelligence (AI), machine learning (ML), Big Data, enterprise systems, cloud applications, etc. More+

NetApp® ONTAP® Select - is an SDS that runs on commodity HW (any server of any manufacturer with internal SAS, SSD, NVMe capacity) with VMware hypervisors, or KVM. It provides high availability, including multi-site solutions -synchronous replication between two systems and MetroCluster SDS technology. More +

Network virtualization

Software Defined Network (SDN)

The software-defined SDN network brings a new perspective on network architecture and management.

It is used in all areas of networking in the form of SD-LAN (Software Defined Local Area Networks), SD-WAN (Software Wide Area Networks), or SDMN (Software Defined Mobile Networks).

They provide a comprehensive and simpler approach to managing large networks with high dynamic demands.

SDN technologies separate power (routing) logic from control and application logic.

 

Routing devices pass network control to central elements, SDN controllers (offered by most manufacturers CISCO, HPE, Juniper Networks, etc.), or open-source controllers in the form of a server with special software, e.g. Open Network Operating System (ONOS®).

The advantage of such a converged infrastructure is the efficient central management of the network, flexible implementation of configuration changes, dynamic changes in properties, better use of network resources, and the resulting savings in operating resources.

 

 

SDNs also use Network Function Virtualization (NFV), i.e. moving most network devices, services, and applications to a virtual environment.

Among the largest vendors and innovators in Software Defined Networks is Cisco Systems, with an architecture that provides a centralized, programmable network. Intent-based network (IBN) built on the Cisco DNA-C (Digital Network Architecture Centre) platform for automation of enterprise LAN, WLAN, and WAN environments.
