What is IaaS?
IaaS (infrastructure as a service) is a cloud service model that offers on-demand infrastructure resources, such as compute, storage, networking, and virtualization, to businesses and individuals via the cloud.
IaaS is attractive because acquiring computing resources to run applications or store data the traditional way requires time and capital. Organizations must purchase equipment through procurement processes that can take months. They must invest in physical spaces, typically specialized rooms with power and cooling. And after deploying the systems, they need IT professionals to manage and maintain them.
All this is challenging to scale when demand spikes or business grows. You run the risk of running out of capacity or overbuilding and paying for infrastructure that you never use.
These challenges are why IaaS use is steadily growing. Learn more about Google Cloud IaaS products and solutions.

Infrastructure as a service—also known as IaaS—is the on-demand availability of highly scalable computing resources as services over the internet. It eliminates the need for enterprises to procure, configure, or manage infrastructure themselves, and they only pay for what they use.
IaaS explained: How does it work?

Software as a service (SaaS)
Because IaaS resources are used on demand and enterprises only have to pay for the compute, storage, and networking resources that are actually used, IaaS costs are fairly predictable and can be easily contained and budgeted for.
IaaS resources are regularly available to businesses when they need them. As a result, enterprises reduce delays when expanding infrastructure and, alternatively, don’t waste resources by overbuilding capacity.
It boosts productivity
Because the cloud provider is responsible for setting up and maintaining the underlying physical infrastructure, enterprise IT departments save time and money and can redirect resources to more strategic activities.
IaaS has no single point of failure. Even if any one component of the hardware resources fails, the service will usually still remain available.
One of the biggest advantages of IaaS in cloud computing is the capability to scale the resources up and down rapidly according to the needs of the enterprise.
It drives faster time to market
Because IaaS offers virtually infinite flexibility and scalability, enterprises can get their work done more efficiently, ensuring faster development life cycles.
Advantages of IaaS
Do you need IaaS?
One of the primary reasons businesses choose IaaS is to reduce their capital expenditures and transform them into operational expenses. IaaS provides storage, compute, and networking options that don’t require them to purchase and maintain vast private server rooms that take up a lot of energy and space.
If you have unpredictable workload volumes or the need to move swiftly in response to business fluctuations, you might also turn to IaaS as a cost-effective way to support your operations.
If your organization experiences any of the following, you’re probably a good candidate for IaaS:
- High business growth that outpaces infrastructure capabilities
- Unpredictable spikes in demand for infrastructure services
- Low utilization of existing infrastructure resources
- Large volumes of data that overwhelm on-premises data stores
- Slow response times with on-premises applications
- Application performance limitations due to capacity constraints
- Slow hardware refresh cycles
These scenarios require more infrastructure scalability and agility than traditional data centers can provide.
Run testing and development
The computing and networking power of IaaS makes it a perfect environment to run and manage testing and development cycles.
Improve disaster recovery preparation
Because IaaS is scalable and reliable, businesses can consolidate disparate disaster recovery systems into one virtualized environment.
Perform big data analysis
Storing and analyzing big data requires a lot of processing power. IaaS is an appropriate environment for big data because it can handle large workloads.
Handle spikes in traffic
IaaS can handle unexpected traffic spikes by scaling as necessary.
Provision resources quickly
IaaS makes it possible to get new projects up and running quickly when urgent business priorities arise.
