What is IaaS?
Infrastructure as a service (IaaS) is a cloud computing model whereby all the infrastructure is provided and maintained by the provider: servers, storage, networking, and so on. With IaaS, an organization can make wise investment in quickly growing with cloud rather than wasting huge amounts on purchasing and installing new hardware. As with IaaS, you simply pay a monthly fee to use resources as per your needs and the cloud provider is responsible for ensuring the maintenance of all the hardware and virtualized services.
IaaS includes virtual server space, IP addresses, network connections, internet connection, firewalls, bandwidth, load balancers etc.
The major appeal behind IaaS cloud computing service is that both the software and hardware used are virtualized. Infrastructure as a service is the foundation and plays an important role for many enterprises on their journey towards Platform-as-a-service or PaaS. It provides them the ability to create base compute images that provide network, storage, and compute resource on-demand via automation.
As other cloud services, IaaS too is witnessing a rapid rise in demand:
”According to a Gartner market analysis report on cloud services over 2013-2016, infrastructure as a service (IaaS) spending will exceed $72 billion, with a compound annual growth rate (CAGR) of 42 percent.”

So, IaaS services can also be used by enterprises to create easily-scalable and cost-effective methods of providing IT solutions.
Thus, IaaS can successfully remove the complexities and expenses associated with your IT infrastructure.
Benefits of having IaaS Cloud computing
IaaS is beneficial for organizations for a number of reasons. Let’s discuss benefits of IaaS in detail-
Resources are distributed as a service: The resources include CPU cores, hard disk or storage space, RAM, virtual network switches, vLANs, IP addresses and more. An IaaS provider provides its users with the hardware and the provisioning software that allows them to work as if they own a physical datacenter.
IaaS is good when you need to expand or scale: It is one of the greatest benefits of IaaS- the ability to scale up or down rapidly in response to a company’s requirements. IaaS providers generally have the upgraded, most powerful servers, storage, and networking technology to accommodate the needs of their clients. This on-demand scalability provides flexibility and greater agility in response to changing opportunities and requirements.
Multiple users can work on a single piece of hardware anywhere and anytime: As IT resources are accessed via an internet connection, IaaS businesses and their employees can work remotely. It’s easy to access work resources while on the move, simply requiring online access and the user’s login credentials. As the modern world of work demands greater flexibility than ever before, so adopting IaaS can help organizations become geographically independent.
IaaS can run even if a server goes down: Infrastructure as a Service provides greater reliability in which cloud providers can spread resources across multiple servers and data centers. It means if a particular hardware component fails, or even if an entire data center goes offline, an organization’s infrastructure would not be affected.
You need to pay for only those services that you need: It is not necessary that all applications are running all the time. However, with many in-house options, the application is made to run and you have to pay for that. What’s the result? The cost is the same whether you use your machine(s) or service(s) for one hour, for few months, or 24/7/365. But with IaaS offerings, you have to pay only for the time when the resources are used and only for those services that you actually need.
Using OpenStack for IaaS
OpenStack is a cloud computing platform. To make the virtual cloud computing technology flexible, IaaS providers and businesses who want to create private or public clouds, need to be able to create and manage VMs fastly.
OpenStack creates abstracted pools of storage, compute, and networking resources that can be used to create VMs on top of the server hardware.
If you want to experience this, go for OpenStack cloud managed by ZNetLive and you will get the service with the following features:
Complete management of application lifecycle.
Ready integration with public clouds and virtualized environments.
Ability to harness full power of an OpenStack cloud.
Implemented DR for Openstack.
Azure IaaS for IT Pros
IaaS gives you the complete control over a server in the cloud (virtual machine). With an Azure VM, you are able to manage everything from the Operating System to the application you are running. Thus, Azure Infrastructure as a Service provides a way for developers to take advantage of the benefits of cloud computing by providing infrastructure resources such as CPU, memory and network on the fly.
Infrastructure as a service is the most flexible cloud computing model and allows for programmed deployment of servers, storage, processing power, and networking. IaaS clienteles have true control over their infrastructure and the main use of IaaS include the actual deployment and development of PaaS, SaaS, and web-scale applications.
