What is Application Virtualization?

Application virtualization is a technology that decouples software applications from the underlying operating system, enabling them to run in a virtualized environment. This process eliminates the need for local installations, allowing applications to be accessed remotely from various devices. By isolating applications from the host OS, it reduces compatibility issues, minimizes software conflicts, and simplifies resource management—making it easier for IT teams to deploy and manage software efficiently.

Unlike traditional installation methods, application virtualization delivers software through network-based virtualization platforms. Users can access their applications on thin clients, virtual desktops, or servers, regardless of the device’s operating system. This approach reduces hardware costs, enhances scalability, and improves the overall user experience. Businesses benefit from a more flexible and streamlined IT infrastructure, enabling seamless software management and deployment.

Getting Started with Application Virtualization

To fully understand the potential of application virtualization, it’s essential to grasp its core principles, key components, and the various types of solutions available. In the following section, we’ll break down these foundational concepts, helping you discover how application virtualization can transform IT operations and streamline software management for businesses.

Definition and Purpose

Application virtualization isolates applications from the operating system, enabling them to run in a self-contained virtual environment. It allows applications to be delivered directly to users without requiring local installation, simplifying deployment, reducing software conflicts, and streamlining patch management.

The primary goals of application virtualization are to:

• Simplify software delivery across multiple devices and platforms.
• Enhance compatibility by isolating applications from the host system.
• Optimize resource management, providing a more scalable infrastructure as businesses grow.

Key Differences Between Virtualization Types

Understanding the distinctions among various types of virtualization is essential for recognizing the unique role of application virtualization in IT environments.

Desktop Virtualization: Delivers a complete desktop environment, including the operating system and applications, to users. In contrast, application virtualization focuses solely on delivering individual applications, reducing system load and improving efficiency.

Server Virtualization: Server virtualization abstracts physical hardware to improve resource allocation and scalability. Application virtualization, on the other hand, isolates software from the host OS to enhance software management and deployment.

Network Virtualization: This optimizes network resources for better bandwidth and performance. When combined with application virtualization, it facilitates seamless software delivery over a network maximizing performance and resource efficiency.

Core Components Required for Implementing Application Virtualization

Successful application virtualization requires a combination of software, hardware, and network infrastructure. Let’s explore the essential components needed to implement virtualization:

Virtualization Software or Platforms: Tools such as VMware, Microsoft App-V, and open-source options help create virtual environments where applications can run independently of local systems. These platforms ensure cross-environment compatibility.

Hardware Requirements: Virtualization necessitates adequate server capacity and thin clients capable of supporting virtualized applications. This infrastructure must also facilitate resource management to maintain optimal performance.

Network Infrastructure: A robust network is critical for the smooth delivery of virtualized applications. Reliable connectivity with low latency is necessary to ensure consistent performance, especially for real-time application streaming.

How Application Virtualization Works

The core principle of application virtualization is separating an application from the host operating system. Instead of being installed directly on the user’s device, the application runs remotely on a server or cloud infrastructure while the user accesses it through the network. The experience is seamless, with the application behaving as if it were installed locally on the device.

The process begins by packaging the application into a virtual environment using virtualization software. This isolates the application’s resources and dependencies from the host system, preventing conflicts with other software. Centralized management becomes more efficient, allowing updates, patches, and rollbacks to be applied seamlessly without disrupting the underlying system or other applications.

There are different models for delivering virtualized applications:

Hosted Virtualization: The application is hosted on a server and delivered to users via the network. This model allows centralized management and updates but relies heavily on network stability.

Streamed Virtualization: With streamed virtualization, applications are delivered on-demand, minimizing local storage needs. The software is accessed while it continues to download in the background, reducing storage overhead.

Local Virtualization: This model involves storing the application locally on the user’s device but running it within a virtualized container. It offers low-latency access but requires more local storage and processing power.

Types of Application Virtualization

There are four types of application virtualization, each tailored to different business needs and system requirements. Understanding the distinctions between them helps businesses choose the right solution based on their performance needs, scalability, and isolation requirements.

Full Virtualization

Full virtualization isolates applications from the underlying operating system and hardware, providing the highest level of security and flexibility. It encapsulates not only the application but also the entire OS within a virtual environment, making it ideal for highly secure or regulated environments.

Examples:

• VMware vSphere: A leading hypervisor-based platform that supports running virtual machines (VMs) across multiple operating systems, ensuring complete isolation of applications.
• Microsoft Hyper-V: A solution for fully virtualizing applications and OSs in Windows environments, offering high scalability and availability.
• Scale Computing HyperCore: A hyper-converged infrastructure platform that supports secure and distributed application deployment.

Partial Virtualization

Partial virtualization isolates only specific components of an application or system. While this offers less isolation than full virtualization, it can be more resource-efficient, especially for legacy applications or simpler software.

Examples:

• Microsoft App-V: Virtualizes individual applications, running them independently of the host OS, making it a prime example of partial virtualization.
• Citrix XenApp: Virtualizes applications for remote access, without the need for a full desktop environment.

Application Streaming

Application streaming allows software to be delivered on-demand, without requiring a full local installation. Users can begin working with the application as it streams, reducing the need for local storage and optimizing bandwidth usage.

Examples:

• Citrix Virtual Apps: Enables on-demand delivery of applications to any device, with real-time streaming capabilities.
• Microsoft App-V Streaming: Delivers applications over a network, allowing on-demand access without consuming local storage.

Containerization

Containerization packages applications along with their dependencies into isolated containers that share the same kernel as the host system. This method is lightweight, fast to deploy, and highly resource-efficient. It has gained prominence, particularly in cloud and DevOps environments.

Examples:

• Docker: A leading platform for containerization, Docker allows developers to package and deploy applications consistently across different environments.
• Kubernetes: A tool for managing containerized applications, ensuring scalability and efficient deployment.

Benefits of Application Virtualization

Virtualizing applications offers numerous advantages, making it an attractive solution for businesses of all sizes. Below are the key benefits that can significantly enhance your IT operations.

Enhanced Compatibility and Isolation

Virtualization addresses compatibility issues by isolating applications from the host operating system. It ensures that programs run reliably without interfering with other software, even if they were originally designed for a different platform. The isolation enhances stability and allows legacy applications to function smoothly on modern operating systems.

Simplified Deployment and Management

Centralizing software delivery and updates streamlines the management process. IT teams no longer need to manually install or update software on each individual machine, saving time, reducing human error, and simplifying patch management. The centralized approach also leads to fewer disruptions and faster deployment cycles.

Scalability for Small Businesses

For small businesses, virtualization is a cost-effective way to scale IT capabilities without substantial investments in physical infrastructure. Virtual environments allow businesses to grow their IT operations without the need for constant hardware upgrades.
