Infrastructure as a Service (IaaS) is a cloud computing service model. As is the case with all cloud computing models of business, IaaS provides access to computing resources in a cloud-based environment.
In the case of IaaS, the computing resources provided are virtualized hardware or a computing infrastructure. Such product offerings range from virtual servers to network connections to load balancers.
The core concept of IaaS
The main appeal behind any cloud computing service is that the hardware and software used is virtualized. The hardware resources used in IaaS are pulled from multiple servers and networks located across multiple offsite data centers and maintained independently of the company using the service.
An organization simply pays a monthly fee to use these resources as needed internally, and the cloud host is responsible for ensuring the ongoing care of the hardware and virtualized services.
The benefits of IaaS
IaaS caters to the same consumer mentality as with two other service models — Platform as a Service (PaaS) and Software as a Service (SaaS) — namely that these services can be used by businesses to create cost-effective and easily scalable methods of creating IT solutions.
The complexities and expenses commonly associated with an IT infrastructure can grow quite inordinate, and yet remain easily overcome through a cloud provider.
That way, if an organization needs to grow with operational fluctuations quickly, they can tap into cloud resources as needed rather than purchase, installing and integrating new hardware internally.
Additional capabilities of IaaS are quite numerous, offering the following solutions:
#1. Enterprise-level infrastructure
IaaS establishes an internal business network in the form of a private cloud and virtual local networks, utilizing a pooled server for storing company data and running applications needed each day.
This basic structure allows for easy business expansion while still providing necessary data protection in a cloud setting.
#2. Cloud hosting
Rather than storing hardware within a business’s facilities, they can host their websites and virtual servers through a pooled collection of physical servers elsewhere. This provides countless benefits, such as security redundancies and on-demand scalability.
#3. Virtual data centers
Creating a virtualized network of interconnected servers can only serve in enhancing cloud hosting capabilities, creating an ideal environment in which a public or private cloud is implemented.
The infrastructure created through IaaS can significantly cut down on expenses and personnel requirements in many different ways. Infrastructure as a Service accomplishes this with the following benefits:
Typically when an organization experiences significant growth, it needs to purchase new equipment, install and implement it and train employees in its use. IaaS cuts out all of the first two steps, allowing for immediately available resources for easy growth.
#5. No hardware investment
Much of the expense associated with a comprehensive IT solution is the hardware.
Rather than spending thousands on servers that might break at any moment, investing in a cloud hosting solution removes the risk of hardware failure and the need for ongoing maintenance.
#6. Utility style cost
Rather than paying for hardware in its entirety and not utilizing it fully, with IaaS you pay for what resources you use, thus saving money over the long term.
#7. Location independent
In the event of a power outage at your place of business, keeping servers in-house can become quite problematic as they’re suddenly unavailable to any consumers that use them. Housing server resources in an independent location ensure
#8. Hardware security
Services made available through cloud hosts have secure data centers with multiple physical security measures.
#9. No single point of failure
Due to the redundant nature of cloud hosts, if one server or network switch were to fail, the data center would remain unaffected due to the numerous hardware resources it would naturally reroute activity levels through.
Even if an entire data center were to fail, the host would have secondary and tertiary centers to ensure continued online function.
Regarding disadvantages, the IaaS model brings with it dependence on a specific provider. As a result, it is critical that the service provider remains an ongoing concern.
Complex resource allocation software is also required to ensure that cloud-based resources are there when needed. It is important to consider what data is sent to the cloud to mitigate any security-related risk.
Another concern with IaaS is that virtual on-demand infrastructure capability coupled with the increasing usage of mobile devices bring with it the challenges associated with the disbursement of resources.
These challenges include the difficulty of preventing employees from circumventing enterprise policies and procedures to use or develop software outside the view of an organization’s official governance programs.
