IaaS has Advantages as well as Disadvantages: Sad but True!

Despite Iaas being cost-saving, having on-demand scalability, running even when the server is down, it has some disadvantages as well in terms of security control for the enterprise, upgrade and maintenance.

Advantages & Disadvantages of IaaS Explained
Published By - Kelsey Taylor

Infrastructure as a service is also known as hardware as a service (HaaS) which is a computing infrastructure that provides virtualized computing resources to the users through the internet. It provides hardware, storage, servers, and data center space and network components. IaaS is one of the four types of cloud computing along with software as a service (SaaS) and platform as a service (PaaS) and serverless.

Some common examples of IaaS providers are Amazon Web Services (AWS), Microsoft Azure, Digital Ocean, Google Compute Engine (GCE), Rackspace, Cisco Metapod, and Linode.

Advantages of IaaS

  • Cost Saving

    One of the benefits of IaaS is lower infrastructure costs; it offers the best in terms of cloud computing. By having IaaS no organization has to worry about maintaining hardware and network equipment, ensuring uptime and replacing old equip. IaaS makes an economical option for start-ups and businesses testing new ideas as it saves the organization from sudden business spikes. Having a third-party service to manage your infrastructure can save your organization a lot of money.

  • On-demand scalability

    One of the greatest benefits of IaaS is that we don’t have to upgrade software, hardware or troubleshoot equipment problems. It can be scaled up and down quickly in response to a company’s requirements. IaaS providers have the most powerful storage, networking technology, and servers to accommodate the needs of their clients.

  • Have the Flexibility You Need

    With the modern work demands greater flexibility, so by adopting IaaS it provides more flexibility to work as employees can access their files and data offsite also in need, they can connect to virtual office easily and quickly.

  • Focus on business growth

    The goal of every business is to grow. Growth will lead to more clients and more workload, which will lead to more data. With the growing business, you need to hire more staff to maintain the technology infrastructure. But with the IaaS, you need not worry because it uses up-to-date technology that easily scales up or scales down to meet your business’ needs. As infrastructure is managed by third-party service, you will be able to focus on other works.

  • It can also run when the server goes down

    IaaS has greater reliability with the service provider. If any particular hardware components fail, or even internet connection fails or entire data go offline, an organization’s infrastructure would not be affected.

Disadvantages of IaaS

  • Security

    The enterprise does not have any control over cloud security in an IaaS environment. They need to review the Cloud Service provider’s service level agreement (SLA) to help them understand its security obligations and thereby identifying gaps in their security coverage.

  • Lack of flexibility

    Service providers maintain the software, but they do not upgrade the software for some of the businesses.

  • Technical problems

    Organizations faces some downtime with IaaS, and it will restrict their access to applications and data.

  • Over Dependency

    Having IaaS in your organization means have a full dependency on the provider or third party for your data

  • Upgrade & Maintenance

    The organization is solely responsible for any upgrades of software and maintenance of tools or data system.

  • Virtualization Services & User-Privacy

    IaaS depends on virtualization services. Also, restricts user-privacy & customization.


Cloud computing is one of the most prominent emerging technology which give appropriate architectural solutions to IT sector. Infrastructure as a service (Iaas) is the most flexible cloud computing model which provides instant access to computing, storage, and network solutions to its clients.

It has many benefits for businesses like reduction in operating costs by spending less on maintenance and software upgrades. As like any growing technology even cloud computing has some challenges as well which must be overcome, like data security. This factor is of utmost concern to every business and IaaS success here can well determine its future scope.
