For businesses across the board, the availability of their IT systems isn’t just a percentage. It translates directly into revenue, security and customer trust. Even brief IT downtime can disrupt operations, damage a company’s image, and drive huge economic losses. This makes keeping infrastructure available 24/7 critical both to operational efficiency and to maintaining your competitive edge.
However, managing your own IT infrastructure can be complex, expensive, and resource-intensive. That’s where Infrastructure as a Service (IaaS) can make all the difference.
What Is Infrastructure as a Service (IaaS)?
Infrastructure as a Service (IaaS) is a cloud computing model where core IT resources—such as compute, storage, and networking—are delivered virtually over the cloud.
You retain control of your operating systems, middleware, and applications, while the IaaS provider manages the physical infrastructure. This balance of flexibility and convenience enables businesses to scale quickly without the burden of managing hardware or data centers.
IaaS also fits seamlessly into hybrid or co-managed IT environments, offering scalability for growing organizations and stability for established enterprises.
How IaaS works
Here’s how Infrastructure as a Service (IaaS) typically functions:
- Virtualization layer: Providers host virtual machines (VMs) and storage across distributed, high-performance servers.
- Access and control: Users manage configurations through a secure web portal or API.
- Usage-based billing: Pay only for the compute, storage, or bandwidth consumed.
- Elastic scaling: Instantly scale resources up or down based on business needs.
- Security and redundancy: Providers ensure data protection, redundancy, and automatic failover for business continuity.
This model underpins modern IT strategies such as DevOps automation, disaster recovery, and hybrid cloud deployments.
Why managing infrastructure in-house is a challenge
Running on-premises infrastructure means handling every layer yourself, from server procurement to performance monitoring.
Common challenges include:
- High upfront hardware investment
- Ongoing maintenance and upgrade requirements
- Downtime risks and redundant systems
- Limited in-house expertise
When your IT team spends more time maintaining systems than driving innovation, growth and agility take a back seat.
What services do MSPs provide under IaaS?
Partnering with a Managed Service Provider (MSP) enhances the value of IaaS. MSPs combine cloud infrastructure with hands-on expertise to manage, optimize, and secure your environment.
Typical MSP-provided IaaS services include:
- 24/7 infrastructure monitoring and performance tuning
- Backup as a Service (BaaS) and Disaster Recovery (DRaaS)
- Patch management and proactive maintenance
- Security management, including firewalls and encryption
- Technical support with SLA-backed response times
- Cloud strategy consulting for hybrid and multi-cloud setups

FAQ
What is IaaS?
IaaS stands for Infrastructure as a Service. In this outsourced cloud computing model, a third party such as Evernex delivers virtualized IT resources, including compute, storage, and networking, over the internet.
How is IaaS different from SaaS and PaaS?
IaaS (Infrastructure as a Service) provides virtualized computing resources, while the business manages its own operating systems, applications and data. PaaS (Platform as a Service) goes further, providing a ready-made environment for building and running applications. SaaS (Software as a Service) is even more complete, delivering a finished application in which the provider manages everything except the business’s data and settings.
What are the benefits of IaaS?
The business benefits of Infrastructure as a Service include improved cost efficiency and agility, specialist infrastructure management, and the liberation of resources to focus on innovation and development.
Who are typical IaaS providers?
Key IaaS providers include Evernex, AWS, Microsoft Azure and OVHcloud, amongst others. The best provider for your business will depend on your IT environment’s complexity, workloads, budget and sovereignty needs.
Is IaaS suitable for small businesses?
Yes, IaaS can be a strong option for SMBs, allowing small companies to avoid the upfront costs (CAPEX) of investing in hardware and allows them the freedom to scale resources up or down as business requirements change.
