IaaS is a form of cloud computing to provide virtualization of the IT infrastructure such as storage, server and networking resources, the infra resources than accessible by subscriber via virtual machines accessible over the internet. Many organizations take advantage of highly available, scalable and secure cloud infrastructure with Azure—and they only pay for the resources that they use.

When to Use Azure IaaS?
Small companies prefers to use IaaS to avoid spending time and money on purchasing and creating hardware and software.
Large companies may like to keep complete control over their applications and infrastructure, but they want to purchase only what they actually use or need.
Companies with rapid growth like the scalability and resilience of IaaS, where they can change out specific hardware and software easily as per their need.
What are the limitations of IaaS?
Security is the major threat as system vulnerabilities may expose data communication between the host infrastructure and VMs to unauthorized entities.
Support of legacy application could be difficult.
As due to multi tenant nature hardware would also get shared hence entire restrictions over data sharing will be dependent on cloud provider.
