IaaS/HaaS solutions are the most developed and popular in the cloud computing market, delivering customizable infrastructure on demand.
IaaS offerings range from single servers to entire infrastructures, including network devices, load balancers, and database and web servers.
Hardware virtualization is the primary technology used, enabling workload partitioning, application isolation, sandboxing, and hardware tuning.
IaaS/HaaS benefits providers by optimizing IT infrastructure usage and enhancing security while reducing customers’ administration and capital costs.
Customers can customize their cloud infrastructure using virtual machines that typically come with only an operating system or prepackaged system images.
IaaS solutions often provide additional services like SLA-based resource allocation, workload management, and infrastructure design support through advanced web interfaces.
IaaS solutions comprise three main layers: physical infrastructure, infrastructure management software, and the user interface.
The infrastructure management software layer includes components like pricing/billing, monitoring, reservation, QoS/SLA management, VM repository, and VM pool manager.
The physical infrastructure can vary from large datacenters to clusters or heterogeneous environments aggregating various computing resources.
Complete IaaS solutions typically offer all three layers as a service, while some solutions only cover the user interface and infrastructure management layers, integrating third-party IaaS providers.
