Service Models of Cloud Computing Explained : SaaS vs. PaaS vs. IaaS

Over the years, cloud service providers have experienced massive growth across the globe. Numbers from Market and Markets state that global cloud services revenue will generate 623.3.4 billion dollars in revenue by the end of 2023. As the business ecosystem evolves, several leading players in the cloud technology sector are vying for their services to be implemented by the public as well as enterprises.rnIn marketing terms, an increase in competition means iteratively better products, in this case, better delivery of services and innovations, all of which could significantly benefit an enterprise in scaling up. With the big leaguers in the game, and smaller players keeping pace, now is the perfect time for you to deploy a cloud services into your business infrastructure.

How can the Cloud be of benefit to your enterprise-

Businesses across the globe are rushing to adopt cloud computing technology to widen the scope of their operations. There are cons to cloud adoption, but it’s pros far outweigh them, making a solid case for the cloud Some of the advantages of cloud computing are- Scalability- Choosing to adopt cloud computing services allows an enterprise to scale its computing resources up or down to accommodate evolving business needs. Affordability – When viewed under a wider lens, cloud services are very affordable, given that they eliminate unnecessary costs of hardware upgradation and maintenance. Security- Cloud service providers function with industry-grade security protocols. This means that a company, working with cloud service providers, is essentially making its data more secure. If you, as an enterprise, have envisioned the goal of making your business more dynamic, then adopting cloud computing services is the path ahead. But with this choice also comes the question as to which of the many cloud computing service models would fit your unique business requirements. To make this decision easier we present a comprehensive correlation of the three major cloud service models.

SaaS vs. PaaS vs. IaaS: Cloud computing service models

Cloud computing service models can generally be categorized into three types- • SaaS (Software as a Service), • PaaS (Platform as a Service). • IaaS (Infrastructure as a Service) Each of these cloud computing models carries its own set of benefits that serve a variety of business needs. But to choose between them, an enterprise must have a clear understanding of each model and should evaluate requirements to find out which of the three cloud computing modules can deliver the intended workflow. rnFor a clearer understanding of cloud service models, here is a brief description of each and its inherent benefits-

1. SaaS

Saas or Software as a service is a cloud service model that gives rapid access to Cloud-based web apps. The cloud computing service providers control the entire computing stack, which is accessible through a web browser. These applications run on the Cloud, and an enterprise can use them through a paid licensed subscription or even free but with limited access. Microsoft office 365, Google G-suite, and Dropbox are examples of SaaS. Benefits: • Affordability SaaS is very affordable, given that it eliminates costs involved in purchase, installation, maintenance, and upgrades of computing hardware within an enterprise. • Ready Accessibility With SaaS cloud computing technology, the enterprise can access cloud computing services from anywhere using any mobile device such as a smartphone or a tablet, thus eliminating the constraints of on-premise software systems. • Immediate Usability SaaS cloud services can be rapidly set up, making them functional in virtually no time. The enterprise just needs to sign up for the cloud computing technology of SaaS and is immediately granted access to fast and powerful computing resources. Why SaaS? SaaS is the ideal choice for businesses that are constrained by budget and resources to acquire on-premise hardware. In addition, enterprises that rely on frequent collaboration for the completion of their projects are perfectly suited to opt for SaaS.

2. PaaS

PaaS or Platform as a Service or PaaS is essentially a cloud base where an enterprise can develop, test, and organize different business applications. PaaS provides a virtual runtime environment, an extremely favorable space for the enterprise to develop and test applications. Resources in PaaS cloud computing services are offered in the form of service, storage, and networking and are manageable either by the enterprise or the cloud computing service providers. Being subscription-based, PaaS gives the enterprise flexible pricing options based on the enterprise’s business requirements. AWS Elastic Beanstalk and Google App engine are two examples of PaaS. Benefits: • Rapid Developmentrn rnGiven that the PaaS cloud computing service providers dispense computing resources such as server-side components, the process is simplified, and the focus of the development team improves. • Wide Programming Language Support PaaS cloud computing services offer support for multiple programming languages. These cloud computing modules allow the adopting enterprise to utilize cloud computing technology to build varied applications for different projects. • Collaboration With PaaS cloud computing services, enterprises can benefit from having enhanced collaboration, which will help integrate their teams dispersed across geo-locations. Why PaaS? IF your project involves multiple developers and vendors, then PaaS cloud computing service providers should be your preferred option amongst the cloud service models available. PaaS leases all essential computing and networking resources, making it easy for the enterprise to create customized applications.

3. IaaS

IaaS or Infrastructure as a Service is basically the virtual provision of computing resources over the Cloud. IaaS cloud service providers can give your enterprise an entire range of computing infrastructures, i.e., storage, servers, networking hardware alongside maintenance and support.rnGoogle compute engine, Microsoft Azure, and Amazon Web Services are some of the leading IaaS cloud computing service providers. Benefits • Minimal Costs With IaaS cloud computing service models, the need to deploy on-premise hardware is eliminated, thus resulting in cost reduction. • Scalability IaaS models, are the most flexible cloud computing service models, allowing the enterprise to scale the computing resources up or down based on usage and demand. • Deployment IaaS cloud computing service models can be up and running in no time, given the ease in the deployment of the servers, processing, storage, and networking. Why IaaS? When it comes to IT hardware infrastructure, IaaS is the most flexible of all cloud computing service models. If the enterprise feels the need to control the hardware infrastructure such as management and customizations, then IaaS is the perfect option. It doesn’t matter whether the organization is a start-up or a massive enterprise, IaaS enables access to computing resources without the organization having to separately invest in them.

Conclusion

Now for the final question. What cloud model would be apt for your enterprise as a solution that delivers the results that you have projected? rnWith the above-mentioned details of all the cloud computing service models, you now have a peek into the nature of these services. Each differs, and it is up to you to ponder over your business requirements and then select one that is most apt for your business needs. Cloud Computing is a disruptive methodology that is rapidly changing how computing is done. But search for a service provider that knows what works and can provide you with an enterprise-grade solution, instead of a shoddy job done in the fastest time or at the cheapest cost. Your cloud computing service providers must have years of aligned experience in leading the market, a provider that through iterative and intuitive consultations, assures a smooth transition from traditional operations to the latest cloud technology allowing your enterprise to reach for the clouds.
