What is infrastructure as a service?
Infrastructure as a service (IaaS) is a label often applied to a particular type of cloud service model. In IaaS, a vendor provides clients with pay-as-you-go access to storage, networking, servers and other cloud services, and organizations use their own platforms and applications within a service provider’s infrastructure. An IaaS model is different from a platform as a service (PaaS) model and a software as a service (SaaS) model.
The IaaS basics
Here are several key features of an infrastructure as a service model:
- Users pay for infrastructure as a service on demand instead of purchasing hardware outright.
- Infrastructure is scalable depending on processing and storage needs.
- Enterprises save the costs of buying and maintaining their own hardware.
- Because data is in the cloud, there can be no single point of failure.
- It enables the virtualization of administrative tasks, freeing up time for other work.⁽¹⁾
For companies without their own data centers, infrastructure as a service models can provide an inexpensive, fast, fundamental infrastructure that can be stretched or terminated as needed. Despite providing this infrastructure, infrastructure as a service requires the customer to deal with installation, configuration and the operation of the necessary software stacks.⁽²⁾
Infrastructure as a service models tend to work well for businesses that have scalable workloads and offer vast control over those resources. They also benefit companies looking to a “pay-for-only-what-you-need” service.
When IBM Integrated Managed Infrastructure Services for Networking leader Annapoorni Chittore was asked what the infrastructure related challenges were that she heard about from CIOs, she responded “Infrastructure should be ‘always on’ and ‘hassle-free’ [and] CIOs are looking for infrastructure as a service in a true sense, with less intervention for the CIO in operations.” Infrastructure as a service works best when it requires minimal investment for future scalability and repair from attacks and vulnerabilities.⁽³⁾
As cloud computing, mobility and the internet of things (IoT) foreshadows a greater reliance on a wide range of infrastructure and service providers. Businesses will display a greater use of multiple infrastructure as a service, platform as a service (PaaS) and statistics as a service (SaaS) providers to meet the full range of IT and application requirements. Further, one of the greatest challenges for CIOs will be the management of several, disparate cloud computing and network service providers. When businesses increasingly rely on more than one network service provider, the ability to have visibility in such a hybrid environment becomes essential.⁽⁴⁾
