IT infrastructure virtualization

Techopedia Explains Virtual Infrastructure

The main purpose of a virtual infrastructure is to bring enterprise-level technology to organizations that cannot afford the large capital required to pay for the hardware, software licenses, setup and continual maintenance of an actual data center infrastructure. The technology involves virtualization, which is the utilization of physical server resources to host logical or virtual servers and networking hardware in order to optimize resources and drive costs down by hosting multiple virtual servers in a single host server.

The idea is that no single server is actually taxed enough to the point that its resource limits are reached so it would be more prudent to make use of these resources by running multiple logical servers that, together, can make use of the actual capacity of the host. This lean approach allows for sharing and distributing resources, which, in turn, promotes flexibility, scalability and lower total cost of ownership.

Benefits of a virtual infrastructure:

  • Scalable – Allows provisioning as many or as few logical servers as required, and users only pay for what they use.
  • Flexible – Allows for multiple server and networking configurations as compared to a hardwired physical infrastructure, which requires more capital and effort to change.
  • Secure – Allows more security to be layered on top of whatever security is already present in the virtual infrastructure because all traffic to the virtual infrastructure goes through the actual physical infrastructure.
  • Load balancing – Allows software-based servers to share workloads easily and distribute them properly so that no single logical server is taxed more than the others.
  • Backup and recovery – Promotes easier backups because everything can be saved somewhere, allowing for quick recovery in other hosts if a few hosts are down. This is almost impossible with physical servers, which have to be revived before services can resume.

Benefits of virtual infrastructure

The benefits of virtualization touch every aspect of an IT infrastructure, from storage and server systems to networking tools. Here are some key benefits of a virtual infrastructure:

  • Cost savings: By consolidating servers, virtualization reduces capital and operating costs associated with variables such as electrical power, physical security, hosting and server development.
  • Scalability: A virtual infrastructure allows organizations to react quickly to changing customer demands and market trends by ramping up on CPU utilization or scaling back accordingly.
  • Increased productivity: Faster provisioning of applications and resources allows IT teams to respond more quickly to employee demands for new tools and technologies. The result: increased productivity, efficiency and agility for IT teams, and an enhanced employee experience and increased talent retention rates without hardware procurement delays.
  • Simplified server management: From seasonal spikes in consumer demand to unexpected economic downturns, organizations need to respond quickly. Simplified server management makes sure IT teams can spin up, or down, virtual machines when required and re-provision resources based on real-time needs. Furthermore, many management consoles offer dashboards, automated alerts and reports so that IT teams can respond immediately to server performance issues.

Virtual infrastructure components

By separating physical hardware from operating systems, virtualization can provision compute, memory, storage and networking resources across multiple virtual machines (VMs) for greater application performance, increased cost savings and easier management. Despite variances in design and functionality, a virtual infrastructure typically consists of these key components:

  • Virtualized compute: This component offers the same capabilities as physical servers, but with the ability to be more efficient. Through virtualization, many operating systems and applications can run on a single physical server, whereas in traditional infrastructure servers were often underutilized. Virtual compute also makes newer technologies like cloud computing and containers possible.
  • Virtualized storage: This component frees organizations from the constraints and limitations of hardware by combining pools of physical storage capacity into a single, more manageable repository. By connecting storage arrays to multiple servers using storage area networks, organizations can bolster their storage resources and gain more flexibility in provisioning them to virtual machines. Widely used storage solutions include fiber channel SAN arrays, iSCSI SAN arrays, and NAS arrays.
  • Virtualized networking and security: This component decouples networking services from the underlying hardware and allows users to access network resources from a centralized management system. Key security features ensure a protected environment for virtual machines, including restricted access, virtual machine isolation and user provisioning measures.
  • Management solution: This component provides a user-friendly console for configuring, managing and provisioning virtualized IT infrastructure, as well automating processes. A management solution allows IT teams to migrate virtual machines from one physical server to another without delays or downtime, while enabling high availability for applications running in virtual machines, disaster recovery and back-up administration.

Network Security and Ethical Hacking

The data and integrity of computing assets that belong or relate to an enterprise’s network are secured by cyber security. Its goal is to defend those assets against all threats.

Cyber security is a broad subject that includes many networks and information security mechanisms, such as data security, digital forensics, ethical hacking, and many more. With that being said, we can conclude that ethical hacking is a subpart of cyber security.

This profession requires a combination of different skills and tools to provide a secure environment for users. Experts need to have a strong understanding of various subjects and to be able to face challenges such as zero-day attacks, ransomware, kill chains, zero-day attacks, etc.

Cyber security expert job description

Experts on cyber security don’t have to hack into the system. By taking all necessary security measures, their role is to protect the system.

A cyber security expert’s prominent role to perform regular audits, discover inefficiencies in the system, and then implement the most efficient technologies to improve the security system. Here are some of the responsibilities that come with this role:

  • By performing routine maintenance, they need to keep the security system updated. 
  • The professional must grant appropriate access privileges for advanced system protection.
  • They have to explain to the organization about the consequences of malicious attacks.
  • They provide various suggestions to improve the security system.

Educational qualifications

The cyber security specialist must have a bachelor’s degree in computer science, information technology, telecommunications, electronics & electrical, or any related field. According to the U.S. Bureau of Labor Statistics, information security analysts’ employment is projected to grow 31 percent by 2029, much faster than the average for all occupations.

Ethical hackers learn and perform hacking professionally, based on the client’s direction, and later, present a maturity scorecard highlighting the system’s overall risk, vulnerabilities, and suggestions to improve. This professional is a hacker who uses their skills to find the loopholes of the given system. The reason behind them being called ethical hackers is that the server/system admin grants permission to see the loopholes. 

Hackers are of various kinds and are referred to according to the hacking system’s purpose. Broadly speaking, there are two main hackers:  White-Hat hacker and Black-Hat hacker. Ethical hacking is carried out by ‘white-hat hackers’ whose role is the same as that of ‘black-hat’ hackers, but the intent is different. In the event of ethical hacking, the hacker uses hacking to safeguard the system.

In cases of international conflicts, terrorist organizations pay cybercriminals to break into security networks. They do so to exploit national security features or extort massive amounts of money by injecting malware and restricting access.

New worms, malware, viruses, and ransomware are multiplying every day, creating a need for ethical hacking services. The predominant advantage of ethical hacking is to prevent malicious attackers from stealing and misusing data.

Ethical hacker job description

Since this is privileged information that may be used for illicit purposes, ethical hackers are legally obliged to disclose any problems they encounter during the course of their work.  Some duties that come with this role are:

Technical support

What Does Technical Support (Tech Support) Mean?

Technical support (tech support) refers to a range services companies provide to their customers for products such as software, mobile phones, printers, and other electronic, mechanical or electromechanical products. Technical support services usually provide users with help in solving some common problems rather than providing training on how to use the product.

Techopedia Explains Technical Support (Tech Support)

Technical support is usually delivered over telephone, via email, over chat (IM) or using special software or software extensions that the user can employ to directly contact tech support. Technical support representatives are very familiar with the ins and outs of the products for which they provide support. If there is a problem that cannot be solved by the tech support, it is escalated to the development team and logged as a bug that should be fixed by a future product update or the next product iteration.

There are a few key types of technical support:

  • Time and Material: This type of support is common in the tech industry. Also known as “break-fix” IT support, the payment of the materials and technician service charge falls upon the customer for a pre-negotiated rate.
  • Managed Services: This is usually given to large-scale customers rather than individual consumers. A list of well-defined services and performance indicators are provided to the customer on an ongoing basis for a fixed rate, which is agreed upon on contract. Services provided could be 24/7 monitoring of servers, 24/7 help desk and the like. This may include on-site visits when problems cannot be solved remotely.
  • Block Hours: This is a prepaid support system where the customer pays for a certain amount of time, which can be used per month or per year. This allows customers to use the hours flexibly without the hassle of paper work or multiple bills.
