Overview
Typically IaaS involves the use of a cloud orchestration technology like OpenStack, Apache CloudStack or OpenNebula. It manages the creation of a virtual machine (VM) and decides on the hypervisor (i.e. physical host) in order to start it whilst enabling VM migration features between hosts, allocates storage volumes, and attaches them to VMs that track usage information for billing and more.
An alternative to hypervisors is Linux containers, which run in isolated partitions of a single Linux kernel running directly on the physical hardware. Linux cgroups and namespaces are the underlying Linux kernel technologies used to isolate, secure and manage the containers. Containerisation offers higher performance than virtualization because there is no hypervisor overhead.
IaaS clouds often offer additional resources such as a virtual-machine
The
The capability provided to the consumer is provision processing, storage, networks, as well as other fundamental computing resources where the consumer is able to deploy & run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, & deployed applications; and possibly limited control of select networking components (e.g., host firewalls).
According to the Internet Engineering Task Force (IETF), the most basic cloud-service model offered by the providers is IT infrastructure – virtual machines and other resources – as a service to subscribers.
IaaS-cloud providers supply these resources on-demand from the large pools of equipment installed in
Economic impact
The global IaaS market is projected to reach a value of $411.9 billion by 2030, expanding at a compound annual growth rate (CAGR) of 22.6% from 2023 to 2030. This growth is primarily driven by the adoption of cloud-based infrastructure within the Banking, Financial Services, and Insurance (BFSI) sector, which employs these technologies to enhance scalability and reduce operational costs.[6]
