Cloud computing is a hot topic for enterprises, but covers a lot of online territory that’s often unexplored. If you are considering switching your business to the cloud, be it application or infrastructure deployment, it’s important that you make note of the differences and advantages of the various cloud services.
There are usually three Cloud models: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Each of these has its own benefits, as well as variants, and it becomes necessary to understand the differences among SaaS, PaaS, and IaaS to know how to best choose one for your organization.
Read the blog to understand the cloud models in detail.
Infrastructure as a service
With the infrastructure as a service model, you are renting only the server hardware and a small amount of software (the hypervisor) to host your application’s virtual machine (VM), where the VM consists of the operating system, associated system software, and the application itself.
IaaS means that VMs are simply moved from on-premises to the cloud. Here, many operating systems and applications can coexist on a cloud server. A thin piece of code called a hypervisor ensures that each one runs in a timely and efficient fashion.
This is the easiest and fastest migration strategy; it offers many benefits, including cost savings. However, it still means that your operations staff will need to perform such tasks as patch management, updates, and upgrades.
Nevertheless, IaaS is one of the most common cloud deployment patterns to date because it reduces the time between purchasing and deployment to almost nothing. Additionally, because it is the most similar to how IT operates today, it provides an easy onboarding ramp for your current IT culture and processes. As we shall see, the bulk of migration especially in the early phases of cloud adoption is to IaaS.
Platform as a service
In platform as a service, the cloud provider maintains all system software, removing the burden of upgrades and patches from the IT department.
In a PaaS deployment model, all that the enterprise needs to focus on is deploying its code on the PaaS machines; the cloud provider ensures that operating systems, database software, integration software, and other features are maintained, kept up to date, and achieve a high SLA.
PaaS provides IT departments with important benefits, most important among them being the cost savings associated with reduced or eliminated maintenance of system software and other rote functions. However, PaaS usually implies some redesign of the application in order to best take advantage of the model.
Software as a service
In software as a service, you simply rent an application from a vendor, such as Microsoft Office 365 for email and productivity. This is by far the most cost-effective of all the options because typically the only work involved for the IT department is provisioning users and data and, perhaps, integrating the application with single sign-on (SSO). Typically, SaaS applications are used for functions that are not considered business-differentiating, for which custom or customized applications encode the competitively differentiating business models and rules.
When choosing how to move functionality to the cloud, you should always be on the lookout for opportunities to use SaaS-based applications. Usually, they will provide you with the highest return on investment.
