IaaS
A cloud model where you rent infrastructure (servers, disks, and network) while managing the systems running on it yourself.
What does it mean IaaS?
IaaS (Infrastructure as a Service) means the provider delivers hardware and virtualization, while you manage the operating system, applications, and data.
The most common example is a virtual server in Azure replacing a physical server in the office. Capacity can be scaled up or down at any time.
IaaS is the closest equivalent to a classic server and is therefore a common first step when migrating to the cloud, but it requires the same level of care for updates and security as a local server.
Practical examples
A company migrates its ERP from a local server to a virtual server in Azure, keeps the same installation, and adds cloud-based backups and monitoring.
Business relevance
IaaS eliminates the cost of purchasing and replacing hardware as well as the risk of hardware failure, while making monthly costs predictable and flexible.
Common mistakes
The most common mistake is migrating without optimization: a server with the same resources as a local one running 24/7 is more expensive than necessary.
