How Virtualization Can Help You Grow Your Business

If you hang around IT circles a lot, you must have heard the words virtualization and virtual machines thrown around in conversations. You’ve probably even heard that these things can save costs and capacity for organizations, and help them grow.

Perhaps you’re already wondering how your business can enjoy these benefits.
This article explains what virtualization is, and takes you through some of the concepts involved with it. It also shows how your company can gain on multiple fronts from adopting virtualization technology.
What is Virtualization?
Virtualization is the process of creating virtual versions of operating systems, servers, and networks.
To understand this, let’s remind ourselves what a ‘virtual’ thing is. That word refers to a non-real representation of something real. For instance, there’s Virtual Reality (VR) which is supposed to mirror reality in some way but isn’t real.
So in virtualization, we create virtual copies of operating systems, servers, networks, and other resources. Instead of these items existing within single sets of hardware, we could have multiple virtual resources existing on a single set of hardware.
For instance, you could have two operating systems— Microsoft Windows and a Linux –running on the same computer. Or you could have several applications on just one server.
But how is this possible?
How Virtualization Works
Today, we operate our computers with very fast CPUs and servers. Typically, we would host a single operating system on one computer, or one application on a server. This often leaves these resources with plenty of unused capacity.
With virtualization, you can make the most of that capacity by running several virtual systems on each of them.
Virtualization happens when a virtualization layer is created to separate the hardware component of a system from the user. This separation allows for the creation of several ‘virtual machines’, or virtual computers each with its operating system and applications. These virtual machines and OS exist on a single physical machine or computer.
Types of Virtualization
There are various types of virtualization, involving different kinds of resources.
- OS Virtualization: The creation of one or more virtual operating systems or machines.
- Server virtualization: This divides a single server into multiple virtual servers.
- Application virtualization: Here you can run applications that aren’t installed on your computer as though they were. This is possible because you separate them from the hardware on which they are supposed to be running.
- Network virtualization: In this situation, you reproduce whole network infrastructure— hardware and software –as a software entity, a virtual network.
- Storage virtualization: Here, you group multiple network storage devices into one large storage unit. You can do this by separating the storage-management software from the supporting hardware component and uniting them virtually.
The Benefits of Virtualization for Your Business
Here’s how virtualization can help your business.
- Reduced Costs
With virtualization, you can handle workloads on a single system that would have taken you two or three such systems to get done. Each system can take multiple operating systems, which means you can deal with different tasks on each OS.
If you don’t have to acquire new infrastructure for every new hire or branch that you open, you’ll save a lot of costs. That’s what virtualization helps you achieve. You only use a fraction of your usual expenses, because you’re making the most of existing resources.
- Manageability
You will need fewer people and tools to manage your resources. That’s because there’s a lot more you can track and take care of from fewer devices.
- Less Energy Use
One problem with running single operating systems and applications on computers and servers is that it consumes a lot of energy. If you had several virtual machines on a single system (with each one running an OS) you would only need to power a single physical system instead of many.
This means your energy bills will be smaller. But it also contributes to environmental sustainability.
- Disaster Recovery and Business Continuity
Virtualization plays a big role in Disaster Recovery.
When there’s a network outage, you risk losing important files. Even if you have them backed up in hardware on site it may take days to retrieve.
With Disaster Recovery, you can have virtual versions of your operating systems, servers, and networks come on within minutes of an outage. This saves your files and allows you to carry on with work in a very short while. Ultimately, it reduces or eliminates downtimes, allowing you to deliver uninterrupted service to your customers.
Some IT service companies like Layer3 provide Disaster Recovery as a Service (DRaaS) to their clients. It’s an important part of the business continuity strategy for many of these organizations.
- Smaller Data Centers
As your resource optimization improves, you’ll find that you don’t need a lot of physical space to host your resources. If you’re able to partition hardware and use virtual servers, you’ll only need a fraction of the data center space you would require if you were going on without deliberate virtualization.
- Increased Productivity
Your team will get more work done when they can use multiple resources. They can turn to the ones that work best for each situation, and call on a wider range of applications whenever they need to get things done.
With increased productivity, there’s the prospect of higher revenues. And because you’re also spending less on fewer physical resources, your margins will likely be higher, and your profits could expand (other things held constant).
Where Can You Get the Best Virtualization Service?
Many firms offer virtualization services. They do so directly, or through partner companies that are closer to client businesses. If you’re in Nigeria and you would like to save costs and grow your business with virtualization, you can do this with Layer3.

PwC Reveals AI Scaling Gap Slows Africa’s Digital Transformation
African CEOs continue to trail their global counterparts in deploying artificial intelligence (AI) across business functions, as they remain stuck in experimental AI phases, finding it difficult to scale initiatives into enterprise-wide deployments.
![]()
This is one of the key findings of PwC’s 29th Global CEO Survey: Africa perspective. It found that more than 150 CEOs in Africa who participated in the survey demonstrate strong operational resilience and reinvention as they navigate currency fluctuations, political uncertainty, infrastructure constraints and supply chain disruptions.
It highlights a slower pace of digital transformation that could limit long-term competitiveness in Africa. While awareness and early adoption of AI are growing, enterprise-wide deployment remains limited, according to the survey.
The survey was conducted from 30 September to 10 November 2025 and surveyed 4 454 CEOs across 95 countries, including Africa.
Skills shortages, fragmented data governance, underdeveloped cloud infrastructure and risk-averse investment strategies are preventing African organisations from moving beyond pilot projects into full-scale AI-driven transformation, it finds.
“AI adoption in Africa is real, but scaling it across the enterprise remains a challenge,” says Christiaan Nel, AI Africa leader at PwC South Africa. “Caution must be balanced with urgency − those investing modestly today risk falling behind competitors scaling rapidly.”
Finding their way
Despite these challenges, African CEOs demonstrate strong operational resilience. The survey shows that 81% are optimistic about improving economic conditions, well above the global average of 65%, while 47% are confident about revenue growth over the next year.
The survey underscores that AI adoption highlights a broader reinvention gap. Only 41% of CEOs have clear AI roadmaps, and 37% formalised responsible AI processes. Skills availability remains a major barrier, with just 37% confident in sourcing and retaining talent for AI initiatives.
PwC research shows that when AI is implemented effectively, African companies experience tangible benefits: 56% report increased employee productivity, 53% gain executive time, 23% see revenue growth, and 25% achieve cost reductions. This confirms that AI can drive efficiency and transformation, but only if infrastructure, governance and investment keep pace, notes the study.
Vikas Sharma, Africa cyber leader at PwC Mauritius, explains: “The challenge is structural. Fragmented cloud environments, unclear data governance and underdeveloped cyber security make scaling AI difficult. Without these foundations, AI initiatives remain tactical rather than transformational.”
Beyond AI, CEOs are using technology to reinvent products, reach new customers and modernise operations. PwC highlights that cloud, analytics and digital frameworks are essential enablers for enterprise-wide AI, helping leaders move from experimentation to transformation.
Importantly, African organisations are using technology to augment rather than replace employees, maintaining workforce stability while improving productivity, it states.
Ambition versus execution
Although 55% of African CEOs consider innovation critical to strategy, only 13% are willing to take high risks in innovation projects.
Underlying capabilities reveal the challenge: just 16% operate dedicated innovation centres, 25% have processes to stop underperforming research and development, and 29% rapidly test ideas with customers.
Lullu Krugel, chief economist and ESG leader at PwC South Africa, adds: “The leaders who build enduring businesses protect their core while creating the future. Operational strength alone is not enough; transformation must be bolder.”
Investment restraint is evident: 59% of respondents report little to no change in IT spending, and only 8% are willing to make large investments despite geopolitical uncertainty. Confidence in acquisitions is lower than the global average, with 40% planning growth through acquisition, compared to 46% globally.
Yet diversification offers a competitive-edge. Nearly half of African CEOs have entered new sectors through services and product offerings in the past five years, generating 24% of revenue from these ventures. Technology leads planned expansion efforts at 17%, followed by real estate, retail and transport/logistics.
PwC concludes that Africa’s CEOs have the ambition and resilience but must move from operational excellence to strategic reinvention. This requires embracing risk as a catalyst for transformation, strengthening digital infrastructure, investing in change leadership and aligning AI adoption with enterprise-wide strategy.
Hannelie Gilmour, consulting and transformation platform leader at PwC South Africa, concludes: “Africa is uniquely positioned to leapfrog global peers. Tomorrow’s stability comes from today’s innovation. CEOs who act decisively will shape the continent’s next chapter.”

Firm Reviews the Evolution of Phishing Threats in 2025

A new Kaspersky review reveals how cybercriminals revived and refined phishing techniques to target individuals and businesses in 2025, including calendar-based attacks, voice message deceptions and sophisticated multi-factor authentication (MFA) bypass schemes.

The findings emphasise the critical need for user vigilance, employee training and advanced email protection solutions to counter these persistent threats moving forward.
Calendar-based phishing targets office workers
A tactic originally from the late 2010s, calendar-based phishing, has reemerged with a focus on B2B environments. Attackers send emails with calendar event invitations, often containing no body text, hiding malicious links in the event description.
When opened, the event auto-adds to the user’s calendar, with reminders urging them to click links leading to fake login pages, such as those mimicking Microsoft.
Previously aimed at Google Calendar users in mass campaigns, this method now targets office employees. Organisations should conduct regular phishing awareness training, such as simulated attack workshops, to teach employees to verify unexpected calendar invites.
Voice message phishing with CAPTCHA evasion
Phishers are deploying minimalist emails posing as voice message notifications, containing sparse text and a link to a basic landing page. Clicking the link triggers a chain of CAPTCHA verifications to bypass security bots, ultimately directing users to a fraudulent Google login page that validates email addresses and captures credentials.
This multi-layered deception highlights the need for employee training programmes, such as interactive modules on recognising suspicious links and advanced email server protection solutions like Kaspersky SecureMail, which detect and block such covert tactics.
MFA bypass via fake cloud service logins
These sophisticated phishing campaigns are targeting multi-factor authentication (MFA) by mimicking services like pCloud (a cloud storage provider that offers encrypted file storage, sharing and backup services).
These emails, disguised as neutral support follow-ups, lead to fake login pages on lookalike domains (e.g., pcloud.online). The pages interact with the real pCloud service via API, validating emails and prompting for OTP codes and passwords, granting attackers account access upon successful login.
To counter this, organisations should implement mandatory cybersecurity training and deploy email security solutions like Kaspersky Security for Mail Servers, which flags fraudulent domains and API-driven attacks.
“With phishing schemes growing more deceptive, Kaspersky urges users to treat unusual email attachments, like password-protected PDFs or QR codes, with caution and verify website URLs before entering any credentials.
“Organisations should adopt comprehensive training programmes, which includes real-world simulations and best practices for spotting phishing attempts. Additionally, deploying robust email server protection solutions ensures real-time detection and blocking of advanced phishing tactics,” comments Roman Dedenok, Anti-Spam Expert at Kaspersky.

NDPC Commits to Balancing Data Privacy, Protection Information

Nigerian Data Protection Commission (NDPC), has expressed its commitment to balance information around data privacy and protection.

Dr. Vincent Olatunji, national commissioner, NDPC, stated this in Abuja, at the National Data Privacy Summit with the theme, “Privacy in the Era of Emerging Technologies,” organised by the commission.
Olatunji said the NDPC, at the moment, was looking at balancing information around data privacy and protection.
“What we are doing is just to look at how to balance information around privacy and protection, which is really important, because as we are innovating, at the same time, we have to consider issues around privacy and protection,” he stated.
He added that the commission has been very bold in taking risks that would bring about growth.
“Our starting point is growing at a very alarming rate, and we are not afraid of anything. We can take risks. And that is why a lot is happening in Nigeria, and this is the level of clarity,” he explained.
In his address, Dr. Aminu Maida, executive vice chairman (EVC) of the Nigerian Communications Commission (NCC), stated that Internet of Things holds promise for Nigeria’s economy.
The EVC, who was represented by Abraham Oshadami, executive commissioner, Technical Services (ECTS), noted that, “in an era in which digital assets, Internet of Things, future digital computing and other transformative technologies are key, and both a cornerstone of building trust for the adoption and a prerequisite for sustainable progress.
“Emerging technologies hold immense promise for Nigeria’s grand economy, but they also introduce complex risks to personal and individual rights.
“So, balancing innovation through post-ethical safeguards and public trust is the first step to ensuring that global digital advancement benefits all Nigerians without compromising their privacy or their security,” he added.
“As we just heard from the Nigeria Police, telecom operators have a vast amount of sensitive historical information daily, including connectivity apps and collaboration on privacy, security, and number protection, both to their and their inheritors,” he said.
Dr. Bako Shurkuk, commissioner for Science, Technology and Innovation, Plateau State, who represented Caleb Mutfwang, Governor of Plateau State, said, emerging technologies can be harnessed to attain sustainable growth.
