Virtualization refers to the creation of a virtual resource such as a server, desktop, operating system, file, storage or network. The main goal of virtualization is to manage workloads by radically transforming traditional computing to make it more scalable. The most common form of virtualization is the operating system-level virtualization. In operating system-level virtualization, it is possible to run multiple operating systems on a single piece of hardware. Virtualization technology involves separating the physical hardware and software by emulating hardware using software. When a different OS is operating on top of the primary OS by means of virtualization, it is referred to as a virtual machine. A virtual machine is nothing but a data file on a physical computer that can be moved and copied to another computer, just like a normal data file. The computers in the virtual environment use two types of file structures: one defining the hardware and the other defining the hard drive. The virtualization software, or the hypervisor, offers caching technology that can be used to cache changes to the virtual hardware or the virtual hard disk for writing at a later time. This technology enables a user to discard the changes done to the operating system, allowing it to boot from a known state. Each resource of virtualization has its own set of advantages and complexities. The technology offers many benefits, including low or no-cost deployment, full resource utilization, operational cost savings and power savings. However, deploying virtualization technology requires careful planning and skilled technical experts. Since the virtual machines use the same resources to run, it may lead to slow performance. Server virtualization Server virtualization is a technology for partitioning one physical server into multiple virtual servers. Each of these virtual servers can run its own operating system and applications, and perform as if it is an individual server.                                                 The Benefits of Server Virtualization:

Reduce number of servers:

Partitioning and isolation, the characteristics of server virtualization, enable simple and safe server consolidation. Through consolidating, the number of physical servers can be greatly reduced.   This alone brings benefits such as reduced floor space, power consumption and air conditioning costs.  

Reduce TCO:

Server consolidation with virtualization Reduces costs of hardware, maintenance, power, and air conditioning In addition, it lowers the Total Cost of Ownership (TCO) by increasing the efficiency of server resources and operational changes, as well as virtualization-specific features  

Increase efficiency for development:

At system development sites, servers are often used inefficiently. When different physical servers are used by each business division's development team, the number of servers can easily increase. Conversely, when physical servers are shared by teams, reconfiguring development and test environments can be time and labor consuming.  

Improve availability and business continuity:

One beneficial feature of virtualized servers not available in physical server environments is live migration. With live migration, virtual servers can be migrated to another physical server for tasks such as performing maintenance on the physical servers without shutting them down. Thus there is no impact on the end user. Another great advantage of virtualization technology is that its encapsulation and hardware-independence features enhance availability and business continuity. Storage Virtualization Storage virtualization is the process of grouping the physical storage from multiple network storage devices so that it looks like a single storage device. The process involves abstracting and covering the internal functions of a storage device from the host application, host servers or a general network in order to facilitate the application and network-independent management of storage. There are three important reasons to implement storage virtualization:

1. Improved storage management in a heterogeneous IT environment
2. Better availability and estimation of down time with automated management
3. Better storage utilization

Desktop Virtualization Desktop virtualization is a virtualization technology that separates an individual's PC applications from his or her desktop. Virtualized desktops are generally hosted on a remote central server, rather than the hard drive of the personal computer. Because the client-server computing model is used in virtualizing desktops, desktop virtualization is also known as client virtualization Desktop virtualization provides a way for users to maintain their individual desktops on a single, central server. The users may be connected to the central server through a LAN, WAN or over the Internet. Desktop virtualization has many benefits, including a lower total cost of ownership (TCO), increased security, reduced energy costs, reduced downtime and centralized management. Network Virtualization Network virtualization refers to the management and monitoring of an entire computer network as a single administrative entity from a single. Software-based administrator's console. Network virtualization also may include storage virtualization, which involves managing all storage as a single resource. Network virtualization is designed to allow network optimization of data transfer rates, flexibility, scalability, reliability and security It automates many network administrative tasks, which actually disguise a network's true complexity. All network servers and services are considered one pool of resources, which may be used without regard to the physical components. Network virtualization is especially useful for networks experiencing a rapid, large and unpredictable increase in usage. The intended result of network virtualization is improved network productivity and efficiency, as well as job satisfaction for the network administrator. Network virtualization involves dividing available bandwidth into independent channels, which are assigned, or reassigned, in real time to separate servers or network devices.   Network virtualization is accomplished by using a variety of hardware and software and combining network components. Software and hardware vendors combine components to offer external or internal network virtualization. The former combines local networks, or subdivides them into virtual networks, while the latter configures single systems with containers, creating a network in a box. Still other software vendors combine both types of network virtualization.

Firewall:

A firewall is software/hardware used to maintain the security of a private network. Firewalls block unauthorized access to or from private networks and are often employed to prevent unauthorized Web users or illicit software from gaining access to private networks connected to the Internet. A firewall may be implemented using hardware, software, or a combination of both.
A firewall is recognized as the first line of defense in securing sensitive information. For better safety, the data can be encrypted.

Access Controls:

Access control a is way of limiting access to a system or to physical or virtual resources. In computing, access control is a process by which users are granted access and certain privileges to systems, resources or information.

In access control systems, users must present credentials before they can be granted access. In physical systems, these credentials may come in many forms, but credentials that can't be transferred provide the most security.

Storage area network (SAN) Storage:

Storage area network (SAN) is a secure high-speed data transfer network that provides access to consolidated block-level storage. An SAN makes a network of storage devices accessible to multiple servers. SAN devices appear to servers as attached drives, eliminating traditional network bottlenecks

SAN solutions are available as two types:

• Fiber Channel (FC): Storage and servers are connected via a high-speed network of interconnected fiber channel switches. This is used for mission-critical applications where uninterrupted data access is required.
• Internet Small Computer System Interface (iSCSI) Protocol: This infrastructure gives the flexibility of a low-cost IP network.

Both provide advantages based on business requirements.

The advantages of SAN include:

• Storage Virtualization: Server capacity is no longer linked to single storage devices, as large and consolidated storage pools are now available for software applications.
• High-Speed Disk Technologies: An example is FC, which offers data retrieval speeds that exceed 5 Gbps. Storage-to-storage data transfer is also available via direct data transmission from the source to the target device with minimal or no server intervention.
• Centralized Backup: Servers view stored data on local disks, rather than multiple disk and server connections. Advanced backup features, such as block level and incremental backups, streamline IT system administrator responsibilities.
• Dynamic Failover Protection: Provides continuous network operation, even if a server fails or goes offline for maintenance, which enables built-in redundancy and automatic traffic rerouting.

Network attached storage (NAS):

Network attached storage (NAS) is a dedicated server, also referred to as an appliance, used for file storage and sharing. NAS is a hard drive attached to a network, used for storage and accessed through an assigned network address. It acts as a server for file sharing but does not allow other services (like emails or authentication). It allows the addition of more storage space to available networks even when the system is shutdown during maintenance.

NAS is a complete system designed for heavy network systems, which may be processing millions of transactions per minute. NAS provides a widely supported storage system for any organization requiring a reliable network system.

 

 

 

Direct Attached Storage (DAS):

Direct Attached Storage (DAS) is a dedicated digital storage device attached directly to a server or PC via a cable. Advanced Technology Attachment (ATA), Serial Advanced Technology Attachment (SATA), eSATA, Small Computer System Interface (SCSI), Serial Attached SCSI (SAS), and Fiber Channel are the main protocols used for DAS connections.

DAS creates data islands, because data cannot be shared with other servers.

A typical DAS device may be an internal or external hard disk drive. Depending on data criticality, disk drives may be protected with different levels of Redundant Array of Independent (or Inexpensive) Disks (RAID). Modern DAS systems include integrated disk array controllers with advanced functionalities

DAS advantages include:

• High availability.
• High access rate due to Storage Area Network (SAN) absence.
• Elimination of network setup complications.
• Storage capacity expansion.
• Data security and fault tolerance.

Domain name registration is a competitive industry, in which domains may be sold in a number of TLDs, including ".com," ".net," and ".org." among others.

Web Hosting:

A Web host is an organization that sells or leases memory space on its servers. Web hosting is typically done in a data center, which provides services to clients that enable them to publish websites on the Internet. A Web host can also provide data center space and an Internet connection for servers owned by others. The service provided by a Web host is called Web hosting.
In France and Latin American countries, Web hosting may be referred to as colocation or housing.

Search Engine Optimization (SEO):

Search engine optimization (SEO) refers to methods used to increase traffic to a website by increasing its search engine page rank.

SEO often involves improving the quality of the content, ensuring that it is rich in relevant keywords and organizing it by using subheads, bullet points, and bold and italic characters. SEO also ensures that the site's HTML is optimized such that a search engine can determine what is on the page and display it as a search result in relevant searches. These standards involve the use of metadata, including the title tag and meta description. Cross linking within the website is also important.
