What is Infrastructure as a Service (IaaS)?

IaaS is a form of cloud computing that provides businesses with computing resources like servers, storage, and networking on-demand through the Internet. With IaaS, businesses can utilize these resources without having to purchase and maintain physical hardware.

Some key advantages of Infrastructure as a Service include:

  • Cost savings compared to on-premises infrastructure
  • Ability to scale resources up or down as needed
  • Faster deployment of resources and applications
  • Increased resilience and security
  • Flexibility to experiment and test new ideas

IaaS enables businesses to be agile and focus on core competencies rather than managing IT infrastructure. Popular use cases include spinning up resources to develop or test applications quickly. Overall, IaaS empowers businesses to innovate and grow without large upfront investments.

How IaaS Works

With IaaS, businesses rent IT infrastructure from a cloud provider on a pay-as-you-go basis. The cloud provider owns and maintains the physical infrastructure and data centers, while businesses access resources virtually. This eliminates the need for businesses to purchase and manage their own servers, storage, and networking hardware.

Some examples of IaaS services include:

  • Compute - On-demand access to virtual machines, containers, serverless computing, etc.
  • Storage - Object storage, block storage, archive storage, etc.
  • Networking - Virtual networks, load balancers, IP addresses, firewalls, etc.
  • Databases - Managed relational and NoSQL databases.
  • Analytics - Big data analytics, data lakes, and data warehousing.

The cloud provider handles infrastructure maintenance, patching, resiliency, and security controls. Businesses have flexibility in how they configure and manage these rented resources via dashboards and APIs.

This on-demand model allows businesses to deploy infrastructure faster, scale seamlessly, and avoid large capital expenditures. The level of administrative control can vary across providers. Overall, Infrastructure as a Service enables businesses to focus less on infrastructure management and more on driving innovation.

With IaaS, businesses convert fixed costs into variable costs aligned with actual usage. By optimizing workloads and using auto-scaling, right-sizing, reservations, and spot instances, businesses can maximize cost savings. Monitoring usage and spending is critical for cost governance.


One of the biggest benefits of IaaS is the ability to easily scale computing resources up or down based on demand. This scalability provides:

  • Flexibility to acquire more resources for seasonal peaks or growth spikes.
  • Agility to develop and test applications faster.
  • Resilience by redistributing workloads across resources.

Auto-scaling tools allow businesses to define rules to automatically scale resources according to utilization metrics. This enables seamless scaling to handle workload fluctuations.

Business Continuity

By leveraging cloud infrastructure, businesses can minimize downtime and ensure continuity:

  • Data is resiliently stored across distributed data centers.
  • Applications can be load-balanced across multiple servers.
  • Traffic can be shifted from one region to another in an outage.
  • Employees can access systems remotely via the Internet.

These capabilities maximize system availability and allow employees to stay productive when working remotely.


IaaS accelerates innovation by enabling faster development of new initiatives:

  • Resources can be spun up quickly to develop or test applications.
  • Built-in automation capabilities streamline infrastructure management.
  • A flexible pay-as-you-go model means no large upfront investment is needed.

This agility allows businesses to experiment more and get new offerings to market faster. DevOps and infrastructure-as-code approaches are easier to implement on Infrastructure as a Service.

However, to maximize these benefits, businesses should closely monitor usage and spending. Cost optimization and governance practices are key to ensuring the most value.

Navigating the Challenges of Adopting Infrastructure as a Service

While impactful, migrating business infrastructure to the cloud comes with some challenges to navigate:

Pricing Complexity

IaaS pricing can seem complicated with myriad service tiers, custom configs, add-ons, and varying discounting. Key pricing risks include:

  • Unanticipated overages from exceeding usage quotas or improper rightsizing.
  • Getting locked into suboptimal instance types.
  • Overpaying due to lack of visibility into unused resources or options.

Careful monitoring, governance, and optimization are crucial to managing costs with IaaS.

Varying Provider Capabilities

All IaaS providers are not equal when it comes to features, flexibility, transparency, and support. Some key considerations:

  • API capabilities and integrations with other tools.
  • Monitoring and cost analytics were provided.
  • Workload migration and hybrid cloud options are offered.
  • Level of customer support and managed services.

Thoroughly evaluating providers is important to ensure the right fit.

Security and Compliance

While IaaS providers offer robust physical and infrastructure security, businesses retain responsibility for configuring platforms and workloads securely. Some key aspects:

  • Understanding the shared responsibility model and provider security controls.
  • Configuring access controls, encryption, security monitoring, and compliance properly.
  • Ensuring provider capabilities meet internal policies and industry regulations.

Migration Complexity

Migrating existing infrastructure and applications to the cloud can be challenging depending on scale, legacy technology constraints, data gravity, and organizational change management. Meticulous planning is required to:

  • Assess application dependencies and interoperability with cloud-native services.
  • Account for potential re-platforming or refactoring required.
  • Develop data migration strategies.
