Typically IaaS involves the use of a [[Orchestration (computing)|cloud orchestration technology]] like [[OpenStack|Open Stack]], [[Apache CloudStack|Apache Cloudstack]] or [[OpenNebula|Open Nebula]].  This manages the creation of a virtual machine and decides on which hypervisor (i.e. physical host) to start it, enables VM migration features between hosts, allocates storage volumes and attaches them to VMs, usage information for billing and lots more.
 
  
An alternative to hypervisors are 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. Also, container capacity auto-scales dynamically with computing load, which eliminates the problem of over-provisioning and enables usage-based billing.<ref>{{Cite web|url=https://www.elastichosts.com/blog/elastic-containers/#thetechnicaldetails|title=ElasticHosts Blog|date=2014-04-01|website=Elastichosts|access-date=2016-06-02}}</ref>

Infrastructure as a service (IaaS) mengacu pada layanan online yang menyediakan API tingkat tinggi yang digunakan untuk menghilangkan berbagai detail tingkat rendah dari infrastruktur jaringan yang mendasari seperti sumber daya komputasi fisik, lokasi, partisi data, penskalaan, keamanan, cadangan, dll. A hypervisor, seperti Xen, Oracle VirtualBox, Oracle VM, KVM, VMware ESX/ESXi, atau Hyper-V, LXD, menjalankan mesin virtual sebagai guest. Kumpulan hypervisor dalam cloud operational system dapat mendukung mesin virtual dalam jumlah besar dan kemampuan untuk menaikkan dan menurunkan skala layanan sesuai dengan kebutuhan pelanggan yang beragam.



Overview

Biasanya IaaS melibatkan penggunaan cloud orchestration technology seperti Open Stack, Apache Cloudstack atau Open Nebula. Ini mengelola pembuatan mesin virtual dan memutuskan hypervisor mana (yaitu physical host) untuk memulainya, mengaktifkan fitur migrasi VM antar host, mengalokasikan volume penyimpanan dan mengattach ke VM, informasi penggunaan untuk penagihan, dan banyak lagi.

Alternatif untuk hypervisor adalah Linux container, yang berjalan di partisi terisolasi dari satu kernel Linux yang berjalan langsung di perangkat keras fisik. Linux cgroups dan namespace adalah teknologi dasar kernel Linux yang digunakan untuk mengisolasi, mengamankan, dan mengelola kontainer. Kontainerisasi menawarkan kinerja yang lebih tinggi daripada virtualisasi, karena tidak ada overhead hypervisor. Selain itu, kapasitas penampung otomatis diskalakan secara dinamis dengan beban komputasi, yang menghilangkan masalah penyediaan berlebih dan memungkinkan penagihan berbasis penggunaan.


IaaS clouds often offer additional resources such as a virtual-machine disk-image library, raw block storage, file or object storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles.


IaaS Cloud sering menawarkan sumber daya tambahan seperti library disk-image mesin virtual, penyimpanan blok raw(mentah), file atau penyimpanan objek, firewall, load balancer, IP address, [ [VLAN|jaringan area lokal virtual]] (VLAN), dan bundel perangkat lunak.

Definisi NIST tentang cloud computing mendefinisikan Infrastructure as a Service sebagai:

Template:Quote

According to the Internet Engineering Task Force (IETF), the most basic cloud-service model is that of providers offering IT infrastructurevirtual machines and other resources — as a service to subscribers.

IaaS-cloud providers supply these resources on-demand from their large pools of equipment installed in data centers. For wide-area connectivity, customers can use either the Internet or carrier clouds (dedicated virtual private networks). To deploy their applications, cloud users install operating-system images and their application software on the cloud infrastructure.<ref>Template:Cite web</ref>Template:Unreliable source? In this model, the cloud user patches and maintains the operating systems and the application software. Cloud providers typically bill IaaS services on a utility computing basis: cost reflects the amount of resources allocated and consumed.<ref>Template:Cite web</ref><ref>Template:Cite web</ref><ref>Template:Cite web</ref><ref>Template:Cite web</ref><ref>Template:Cite web</ref>
