What are the Different Types of Cloud?
CyNexLink Blog • December 18, 2017
Cloud computing has become ubiquitous in recent times among SMBs for its ease of use and complex efficiency. There are many benefits to this technology, but one of the most favorable outcomes is the automation of storage, which eradicates layers of excess management. No longer will the business be responsible for the maintenance of physical centers of data and associated hardware and operating systems.
Yet, cloud systems aren’t uniform. Once businesses have decided to run with a cloud platform, they need to be aware of the varying systems. The three main categories of cloud service models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).
Here’s an explanation of each model:
- Infrastructure as a Service (IaaS): This is a self-service platform that manages remote data center infrastructures. Within this model, third-parties like Amazon Web Services, Google or Microsoft Azure host the computing resources provided by IaaS.
The purchasing of IaaS for a company is based solely on what it plans to use. Many IT departments or organizations utilize IaaS because of its familiarity.
IaaS is desirable for projects that are temporary, experimental or subject to change. IaaS generally is charged on a per-use basis, though providers also charge based on the amount of utilized virtual machine space.
- Platform as a Service (PaaS): This model allows companies to construct, use and manage applications without an on-the-ground IT infrastructure, making it easier and quicker to develop and use applications. This system eliminates worries about having to deal with time-demanding IT infrastructure issues like provisioning servers, storage and backup because it hosts the hardware and software on its own infrastructure.
PaaS is generally considered to be simpler and more convenient due to providing the infrastructure and other IT services with easy accessibility on a web browser. Another desirable aspect of this system is the lowering of costs and minimization of management overhead. Innovation and scaling the business is also easier with PaaS.
Access is generally charged on a per-use basis, although some providers charge a monthly rate.
- Software as a Service (SaaS): This form replaces on-device software with software licensed through subscriptions. A majority of SaaS applications are accessed through a web browser, bypassing any downloads or installations. Some do require plug-ins though.
Generally, the service is paid for on a monthly basis, which allows for businesses to practice better budgeting due to the predictive nature of the payments.
There is high scalability with this platform due to the on-demand nature of its access. Further taking the burden off of companies, SaaS providers automatically initiate updates and patch management so new software doesn’t need to be purchased.
