There are various types of cloud computing out there for businesses to choose from when shifting workloads from onsite infrastructure to a cloud deployment. First and foremost, cloud computing takes three primary forms:
- Infrastructure as a Service (IaaS): Internet-based access to data centers, cloud storage, and computing power. Essentially, your brand rents IT infrastructure including servers, data center storage, networks, virtual machines, and operating systems.
- Platform as a Service (PaaS): Designed to give developers the tools needed to build and host web applications. This builds on IaaS to give developers the infrastructure and applications required to build, deploy, and manage programs.
- Software as a Service (SaaS): The overarching type of cloud computing, SaaS delivers software applications over the Internet with cloud providers hosting and managing the software.
These varying types of cloud offerings can be deployed on public clouds, private clouds, and hybrid clouds. Public cloud computing solutions are entirely managed by a third-party cloud vendor. You pay less money each month because computing resources, data center access, and servers for data storage are shared by all users taking advantage of a public cloud services.
On the other side of the coin, you will find a private cloud environment. Instead of relying on a third-party vendor to manage data, computing resources, and infrastructure, companies provide these services only to select users on an internal network. Your company has greater control over not just access in a private cloud, but the actual structure of that network and the services it offers. Computing resources are still delivered over the internet, but instead of allowing general public access, private clouds and their resources are limited to your business.
In between, hybrid clouds offer a mixture of services that some might find suitable for their brand and their budget. For example, in a hybrid cloud environment, you don’t have to bring all of the network infrastructure, maintenance, and management onsite in your business, but you can pay to have computing resources, cloud-based storage, and other cloud services devoted only to your business.
