In 2024, the adoption of Infrastructure as a Service (IaaS) continues to reshape how small to mid-size businesses (SMBs) manage their digital infrastructure. With a significant portion of the nearly $600 billion spent on public cloud services in 2023 allocated to IaaS, its role in business growth is more pronounced than ever. SMBs are increasingly relying on IaaS for its scalability, cost efficiency and flexibility.

What Is IaaS?

Infrastructure as a Service is a cloud computing solution offering essential resources such as computing power, storage and networking over the internet on a pay-as-you-go basis. It’s like renting high-powered computers and storage spaces as needed without the hassle of ownership and maintenance.

To understand the impact of IaaS, let’s compare it with traditional IT infrastructure:

Traditional IT Infrastructure Model Infrastructure-as-a-Service Model
Ownership Typically a physical server box owned or leased by the business Virtual servers managed by the service provider
Maintenance Involves hardware, networking, cabling and environmental controls Handled by the service provider, reducing the in-house burden
Cost and Investment High upfront investment for hardware and facilities Lower upfront costs with a subscription-based model
Scalability Requires purchasing/installing new hardware; less flexible Easily scalable, resources adjustable on-demand
Location Physically located on-premises, limited remote access Accessed remotely over the internet, enhancing flexibility
Management  Requires in-house expertise in various IT domains Maintenance and expertise provided by the service provider
Customization Full control over hardware and configurations Configurable but may have some limitations

How Does IaaS Work?

IaaS streamlines IT infrastructure management by utilizing cloud computing architecture. This approach encompasses virtualization, automation and containerization, each playing a crucial role in enhancing efficiency and flexibility.


Virtualization involves creating virtual versions of physical resources such as servers and storage devices in order to run multiple independent virtual systems on a single physical server, thus optimizing resource use and offering flexibility in resource allocation.


IaaS automates the setup, deployment and management of resources. It minimizes manual intervention, enabling efficient scaling and reducing the risk of human error.


Containerization isolates applications in containers with their own environments. This ensures portability and consistency across different computing environments, simplifying application deployment.

These components collectively simplify the engineering experience in IaaS. With server management and infrastructure complexities handled by the provider, engineers can focus solely on building and deploying virtual components of their IT infrastructure.

SaaS vs. PaaS vs. IaaS

Cloud computing offers varying service models, each catering to different business needs. The three most common are Infrastructure as a Service, Platform as a Service (PaaS) and Software as a Service (SaaS). Below is a comparative table explaining the differences for businesses utilizing these three platforms:

IaaS PaaS SaaS
What It Includes Services, storage, networking and virtualization Hardware and software tools on top of an IaaS platform Ready-to-use software available over the internet
Primary Use Provides the basic infrastructure of servers, storage, etc. Offers a platform for software development and deployment Delivers software applications to the end-user
User Control High level of control over the infrastructure Limited control over the infrastructure, more on the application No control over the infrastructure or platform
Management Users manage the infrastructure; provider manages physical hardware Provider manages the infrastructure and runtime environment Provider manages everything, including applications and data security
Target User Businesses needing flexibility and control over their IT environment Developers focusing on application development, not infrastructure End-users needing immediate access to applications without maintenance
Example Virtual servers for hosting websites or applications Development environments for building software applications Email services, CRM systems, office tools

4 Business Benefits of Using IaaS

Infrastructure as a Service offers significant advantages for modern businesses, streamlining operations and enhancing efficiency. Here are four key benefits:

On-demand Scalability

IaaS allows businesses to quickly scale IT resources to match demand, ensuring efficiency during peak times and cost savings during slower periods. This flexibility is crucial for adapting to market changes without large capital investments.

Cost-efficiency and Predictable Pricing Models

Shifting to an operational expenditure (OPEX) model, IaaS reduces the need for upfront hardware investments. Its subscription-based, pay-as-you-go pricing provides predictable financial planning, helping businesses manage budgets more effectively.

Quicker Deployment Time

IaaS speeds up the deployment process, bypassing the time-consuming setup of traditional IT infrastructure. This rapid deployment capability enables businesses to bring their products and services to market faster, providing a competitive advantage.

Reduced Burden of Infrastructure Management

By transferring the responsibility of physical infrastructure management to the service provider, IaaS allows companies to focus on core business activities. This shift reduces the complexity of IT management and enables businesses to benefit from the provider’s expertise and technology.

Common Challenges of IaaS

Adopting cloud Infrastructure as a Service can bring transformative benefits to businesses, but it’s not without its difficulties. Here are some common challenges and best practices for addressing them:

  • Unexpected costs: Monitor and manage resource usage to avoid escalating costs, especially during peak usage times.
  • Process changes: Adoption may require workflow adjustments. Plan for a transition phase and educate staff to adapt to new processes.
  • Runaway resources: Implement strict policies for resource allocation and de-provisioning to prevent resource wastage.
  • Security risks: Businesses are responsible for securing their data on the cloud. Implement robust data security measures and regularly update them.
  • Lack of support: Ensure your provider offers strong customer support. Managed service options can provide additional assistance.
  • Complex integration: Smooth integration is key. Engage experts for a seamless transition and ensure compatibility with existing systems.
