An Entrepreneur Must Consider While Choosing a Suitable Cloud Delivery Model

SaaS vs IaaS vs PaaS

Everyone knows that the cloud is a very broad concept and before choosing a cloud service delivery model for your application or infrastructure deployment, it’s important for an entrepreneur to look out the fundamental difference between the cloud services available. There are three models of cloud service available: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) and depending on the requirement a user can opt for any of the three models. Let us discuss in brief about SaaS vs IaaS vs PaaS

SaaS: Software as a Service

SaaS providers host an application and targeted the end users through the internet, usually user need to log into the cloud service through a browser and start using the service. The most familiar examples that users commonly interact with are Gmail, Dropbox, Salesforce, Google Docs, Microsoft 365, etc.

Working: SaaS providers usually work on the Subscription model, you pay for what you consume. As SaaS uses the web delivery model, reduces the need to install and run applications on individual computers. With SaaS, the user does not need to setup or maintain the software themselves as Saas provides the ‘on demand’ infrastructure for software and reduces the cost and time for deployment. In addition, Saas maintains the background infrastructure and offers a high percentage of ‘up’ time which enables the users to always be productive. Some SaaS providers may give free trials for a limited period or provide some feature s for free to try out.

PaaS: Platform as a Service

PaaS works at a lower level than SaaS, providing a framework for which applications can be developed and customized. It typically aimed at developers provides a platform to deploy your code without bothering about underlying runtime, operating system, or server infrastructure. The ideal example would be Google App Engine, Windows Azure, Heroku, Force.com, Apache Stratos, OpenShift, etc.

Working: The working model of PaaS is much similar to the SaaS. PaaS provides the platform for developing or creating applications where SaaS delivers the software over the internet. In PaaS, the platform is delivered over the web and allows developers to build, develop, deploy, or test the app without having to worry about provisioning the servers, storage, and backup associated with developing and launching an app. Developers can choose a programming language that suits their business model – Java, NodeJs, PHP, etc. and write code and deploy it on the PaaS provider. All the back-end stuff from fixing bugs to setting the servers will be done automatically in the background and that’s the promise of PaaS.

IaaS: Infrastructure as a Service

IaaS is the fundamental building block for the cloud computing model. The ‘Service’ company is comprised of highly automated computer resources in the form of hardware, networking, and storage which can be self-provisioned, metered, and available on-demand without having to worry about buying and maintaining server infrastructure. With IaaS you can choose your own OS, runtimes and application code. Iaas targeted the vendors, so some famous IaaS vendors are AWS (Amazon Web service), HPCloudCloudSigma etc.

Working: IaaS delivers infrastructure services to organizations such as virtual machines and other resources like virtual-machine disk image library, storage, networking services (e.g. firewalls), load balancers, IP addresses, etc. These cloud services are provided to the user through a dashboard and IaaS users have complete control over the infrastructure as well as user can access their servers and storage directly, all outsourced through a “virtual data center” in the cloud.

As compared to SaaS, IaaS vs PaaS clients is responsible for managing aspects such as runtime, middleware, OS, application, and data. However, IaaS providers offer more services above the virtualization layer such as message queues and database. What user gain with IaaS is the development and deployment of PaaS, SaaS, and web-scale applications.
