On-Premises vs. Cloud Virtualization: What is the Right Choice for Your Business?

Articles

In the digital transformation era, businesses constantly seek innovative ways to modernize their IT infrastructure. Legacy system virtualization has emerged as a game-changer, allowing organizations to optimize resources, increase scalability, and reduce costs. As a leading virtualization solution provider, Stromasys provides two options: on-premises and cloud virtualization.

In this article, we delve into the advantages of both approaches, helping you make an informed decision based on their specific business needs.

What is Virtualization?  

Virtualization is creating multiple virtual ecosystems from a single hardware system. This method is highly popular in the IT sector, especially for cloud computing. For example, a single physical server can function as multiple independent servers via virtualization. This method can be achieved by running different virtual ecosystems on the same physical hardware server.

This procedure’s core is known as a hypervisor, a critical software that stimulates the resources. It then allows them to create and manage the virtual ecosystem smoothly. Due to advanced business challenges, virtualization is highly integrated into the IT infrastructure. It offers scalable, secure, and flexible options to manage IT resources. It not only improves operational efficiency but also significantly reduces costs and gives a competitive edge to businesses.

What is Cloud Virtualization?

Cloud virtualization is a model that relies on virtualization. Businesses can accelerate their digital transformation by migrating legacy systems to cloud infrastructure. Cloud virtualization opens up possibilities for businesses seeking enhanced scalability and cost-efficiency. With cloud platformssuch asMicrosoft Azure, AWS, Google Cloud, and Oracle Cloud, organizations can scale their resources based on demand, paying only for what they consume.

What are the Advantages of Cloud Virtualization?

Here are the advantages of opting for cloud virtualization for migrating legacy systems

• Preservation of Legacy Systems: Many businesses still rely on legacy systems for mission-critical applications. By opting for cloud virtualization, they can easily run their applications on a modern cloud platform without replacing the original source code.  

• Enhanced Performance: Legacy systems that are migrated to the cloud often show significant performance boosts due to the enhanced processing power and resources available on modern cloud infrastructures. Old hardware has limitations that hinder smooth operation and result in poor performance.  

• Cost-Efficiency: Maintaining aging legacy hardware is expensive, as it is prone to wear and tear. It is also a significant cause of unplanned downtime. By virtualizing this outdated legacy in the cloud, businesses can significantly reduce their hardware maintenance costs, minimize energy consumption, and reduce the risks associated with obsolete hardware.  

• Scalability and Flexibility: Cloud environments are highly flexible and scalable. This means businesses can easily integrate other applications without any hassle for seamless operations, which was not possible earlier due to the limitations in legacy systems. This scalability not only improves overall system performance but can also manage peak loads.  

• Enhanced Security: Modern cybersecurity challenges require advanced security measures, which modern cloud infrastructure is equipped with. Cloud providers invest heavily in security measures to create a robust security environment. The latest security measures include advanced firewalls, intrusion detection systems, and regular security updates. Additionally, cloud environments typically offer better data encryption and access control options. Legacy systems often lack such security measures, which makes them more vulnerable to cyber threats and data breaches. 

• Disaster Recovery and Business Continuity: Legacy systems are vulnerable to disasters and other such instances, which may result in data loss and damage. With cloud virtualization, businesses can create backup and recovery features for such incidents. It can significantly improve an organization’s ability to recover from disasters or system failures, ensuring business continuity.  

• Extended Lifespan: With time, legacy systems reach their end-of-life cycle period. With cloud virtualization, businesses can easily extend their life and continue operating.

What is On-Premises Virtualization?

On-premises virtualization empowers businesses to maintain complete control over their IT environment. For companies with stringent security and compliance requirements, it offers a higher level of data privacy and control than cloud virtualization. Critical data remains within the confines of the organization’s data center, reducing exposure to potential external threats.

What are the Advantages of On-Premises Virtualization?  

Here are some advantages of on-premises virtualization of legacy systems:

• Security and Compliance: On-premises virtualization gives businesses complete control over their infrastructure, which means they have direct control over security measures, including physical access to servers, network security, and data encryption. It is crucial for businesses with strict regulatory standards like healthcare (HIPAA), government sectors, and financial industry (PCI DSS) that their sensitive data remains in their physical premises, which makes complying with data protection laws and industry-specific regulations.  

• Customization and Flexibility: Businesses can tailor their virtualization setup to meet specific performance requirements and integrate seamlessly with existing systems.  

• Network Performance: On-premises virtualization minimizes network latency, ideal for applications requiring stringent response time. It is especially beneficial for those businesses that handle massive amounts of data or deal with real-time processing.  

• Utilization of Existing Infrastructure: Many businesses invest heavily on the IT infrastructure. With on-premises virtualization, they can efficiently leverage their existing investments and extend the life of their current legacy hardware. It will save their expense on the new infrastructure and be less time-consuming.  

• Offline Accessibility: Unlike cloud virtualizations, on-premises virtualizations do not require internet connectivity. This means legacy systems can be accessed anytime, even during internet outages.

Hybrid Approach: Best of Both Worlds  

In many cases, businesses find that a hybrid approach is the ideal solution. Stromasys recognizes the importance of flexibility and offers the option to leverage both on-premises and cloud virtualization. A hybrid approach allows organizations to perfectly balance control, security, scalability, and cost efficiency.

What are the Advantages of the Hybrid Approach?

Here are some advantages of the hybrid approach:

• Data Flexibility: Businesses can choose where specific workloads reside based on their data sensitivity and performance requirements.  
• Geographic Redundancy: Organizations can deploy virtualized systems across multiple cloud regions or data centers, enhancing redundancy and disaster recovery capabilities.

Final Takeaway

Making a selection between on-premises and cloud virtualization depends on the business requirements. On-premises computing uses local hardware, offering more control and potentially better security, but it requires maintenance and infrastructure costs. Cloud virtualization, utilizing virtual resources over the Internet, offers flexibility, scalability, and often lower costs.

Neither option is inherently superior. The choice depends on an organization’s specific needs, such as data control requirements, scalability needs, budget constraints, and long-term IT strategy. Therefore, businesses must carefully evaluate the factors to make an informed decision that aligns with their business goals and operational realities.

Ultimately, the best solution varies for each organization based on its unique circumstances and objectives.
