The definition of infrastructure as a service (IaaS) is pretty simple. You rent cloud infrastructure—servers, storage and networking—
on demand, in a pay-as-you-go model.
Since you don’t need to invest in your own hardware,
IaaS is perfect for start-ups or businesses testing out
a new idea.
Also, since the infrastructure scales on demand, it’s great for workloads that fluctuate rapidly.
Your business rents infrastructure from the cloud provider,
and accesses that infrastructure over the Internet, in order to create or use applications.
IaaS is the fastest growing area of cloud computing.*
Enterprise public cloud spending is expected to reach $207 billion
Common public IaaS workloads: dev/test, website hosting, storage, simple application development
But some workloads require an advanced solution.
Managed IaaS is suited for large enterprises running production workloads.
