IAAS in Cloud Computing

The internet is constantly growing, introducing innovations like cloud computing, a field projected to be worth $800 billion by 2025.

Similarly, Infrastructure as a Service (IaaS) — another arm of cloud computing, is expected to grow to $304.39 billion by 2029.

This article closely examines these tools, what they offer, and how they can benefit your business.

What Is IaaS?

IaaS is a model of cloud computing that provides on-demand access to cloud-based servers, storage, and networking.

It operates on a pay-as-you-go model and is a growing, profitable market, with 90% of providers experiencing growth in 2020.

What Does “As A Service” Mean?

The term "as a service" in IaaS highlights the shift from traditional IT, where companies buy and manage their IT resources, to cloud infrastructure.

In cloud computing, the provider owns and maintains these resources, and customers access them over the internet and pay as they use.

With IaaS, you have two main options:

The key advantage of IaaS is that it allows you to use IT networking resources without purchasing or managing them.

You only pay for what you need, while the service provider handles the management and maintenance.

What Is Cloud Computing?

What Is Cloud Computing

Cloud computing is the delivery of hosting services on demand via the internet.

It allows you to remotely store files in a virtual space, eliminating the need for on-site data centers or devices.

Cloud computing offers a variety of resources to users:

  • Data Storage
  • Servers
  • Databases
  • Networking
  • Software

There are two primary cloud types:

  • Private Cloud: Accessible by anyone, offering services to all users.

  • Public Cloud: A more exclusive data center, hosting services for a select group of users.

Benefits Of IaaS

Easy Onboarding

IaaS offers a cost-effective and swift cloud migration for apps and workloads without needing to change the underlying architecture.

This, in turn, boosts performance, enhancing security, and reducing operational costs.

Agility and Speed

IaaS enhances the efficiency and agility of test and development processes.

  • Quick Setup and Dismantling: Accelerates the creation and removal of environments.
  • Faster Market Introduction: Speeds up the launch of new applications.
  • Cost-Effective Scaling: Simplifies and reduces the cost of expanding test and development environments.

Data storage, Backups, and Recovery

IaaS offers a streamlined approach to data management and scalability.

  • Cost Savings: Eliminates expenses related to in-house storage management.
  • Expert Management: The provider handles all legal, compliance, and technical aspects.
  • Handling Demand: Efficiently manages sudden or steady increases in data needs.
  • Backup and Recovery: Simplifies planning and execution of data backup and recovery systems.

Comprehensive Web Support

IaaS provides essential infrastructure for web apps, including storage, servers, and networking. It allows businesses to rapidly build and scale web apps as demand fluctuates.

High-performance Computing

IaaS facilitates high-performance computing for tackling complex, calculation-intensive tasks.

  • Supercomputing Platforms: Uses supercomputers, grids, and clusters.
  • Complex Problem Solving: Aids in addressing intricate issues with many variables.
  • Diverse Applications: Useful for earthquake simulations, weather forecasting, financial modeling, and product design evaluations.

Cost reduction

IaaS offers superior value by eliminating the need for physical data centers and reducing costs through its flexible pricing model.

  • No Physical Data Center Costs: Companies save on setting up and managing physical infrastructure.
  • Pay-as-you-go Pricing: Costs align with actual usage, lowering hardware expenses.
  • Reduced Maintenance: Shifts the technical burden to the IaaS provider, freeing up your team to focus on business objectives.

Superior stability and reliability

With IaaS, the provider manages software and hardware maintenance, upgrades, and troubleshooting, ensuring your infrastructure is reliable and meets service-level agreements.

Minimized Downtime

IaaS protects your underlying infrastructure from external problems like hardware failures, internet outages, and data loss, ensuring it remains secure and operational.

Drawbacks Of IaaS


Businesses have no direct control over IaaS cloud security and need to review the provider's SLA for security details.

To ensure safety, users must scrutinize the SLA to identify and address any potential security gaps.

Technical Issues

Sometimes, businesses may face downtime with IaaS, restricting access to applications, data, and workloads.

Uptime depends on provider

  • Complete Control Risk: Relying solely on IaaS makes you dependent on the provider.
  • Third-Party Issues: Provider problems can directly impact your business.
  • Data and Workload Vulnerability: Issues with the IaaS provider can jeopardize your data and operations.

Incompatibility with existing infrastructure

IaaS may necessitate adjustments to business processes and workloads for some companies.

Can be difficult to integrate

Some businesses may find integrating IaaS with their current systems challenging.

Selecting a competent provider

Selecting an IaaS provider can be challenging due to the complex vetting process.

Other Cloud Service Models

Cloud Service Models


In the PaaS (platform as a service) model, cloud providers offer development tools on their platforms, accessible via APIs, web portals, and gateways.

PaaS is used for creating generic software, and providers often host the software upon completion. Examples include Google App Engine, Microsoft Azure, and Heroku.


SaaS (Software as a service) is a way to deliver software over the Internet, allowing users to access applications from anywhere via a PC or mobile device with an Internet connection.

It gives users access to both software and databases. Examples include Shopify, IBM Cloud, and Oracle Cloud.

IaaS vs. Traditional IT Infrastructure

In the fast-changing IT world, businesses must decide between using Infrastructure as a Service (IaaS) or traditional IT.

Knowing the differences and benefits of each is crucial for informed choices.

Here are the key distinctions:

IaaSTraditional IT
Cost EfficiencyPay-as-you-go model eliminates upfront hardware costs, reducing financial barriers for businesses of all sizes.High upfront capital expenses for hardware and ongoing maintenance costs can strain budgets.
ScalabilityEasily scale resources up or down in response to changing demands, ensuring optimal resource utilization.Scaling requires purchasing new hardware, often resulting in overprovisioning or underutilization.
Maintenance and ManagementService providers handle hardware maintenance, software updates, and security, freeing up IT teams.In-house teams are responsible for maintaining and securing hardware, diverting resources from strategic initiatives.
Agility and SpeedRapid provisioning of resources accelerates development, testing, and deployment of applications.Lengthy procurement cycles can hinder project timelines and time-to-market.
Disaster RecoveryBuilt-in redundancy and data backup options enhance disaster recovery capabilities.Developing robust disaster recovery solutions can be complex and costly.
SecurityProviders invest heavily in security measures and compliance, offering robust protection.Security measures are as strong as the organization's budget and expertise allow.
FlexibilityExperiment with different configurations, operating systems, and software without hardware constraints.Hardware choices can limit flexibility and require costly upgrades for changes.
Environmental ImpactConsolidated data centers and efficient resource allocation contribute to greener computing.Legacy infrastructure can be energy-intensive and less eco-friendly.

IaaS in DevOps Practices

Incorporating IaaS into DevOps practices can streamline development, enhance collaboration, and improve the efficiency of your software delivery pipeline.

Here are key ways IaaS supports DevOps:

  • Resource On-Demand: Get the resources you need when you need them, ensuring scalability.

  • Automated Provisioning: Use automation tools and APIs for infrastructure setup, allowing for efficient management and deployment.

  • Consistency Across Environments: Maintain uniform infrastructure settings for development, testing, and production to reduce deployment issues.

  • CI/CD Integration: Seamlessly integrate IaaS into your CI/CD pipeline for automated testing, deployment, and monitoring.
