In the current digital dynamic economy, cloud computing has turned out to be the support of business information technology. It does not matter whether you are a fast-growing startup or a large enterprise planning to modernize legacy platforms; the choice of cloud model that would better fit your operations needs to be considered. Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) are the three leading models of providing service, and each brings certain value in its way, but the determination as to which model suits your organization lies in the objective, resources, and the level of maturity about digital assistance.
Understanding how each of the models functions, what is specific about them, and how to determine which one will suit your business needs the most, empowers you to make informed decisions in your cloud strategy.
The Cloud Service Models at a Glance
Infrastructure as a Service (IaaS)
IaaS makes available virtual information technology resources on the web. It brings on board servers, storage, networking, and virtualization, whereby organizations can rent IT infrastructure on a per-use model.
Scalability is one of the key benefits of IaaS because businesses can either add or subtract resources depending on their demand at that particular time. It is also very flexible since users dictate terms as to operating systems and applications. In addition, it is economical, enabling organizations to save capital in purchasing physical hardware.
The common example of the utilization of IaaS is those companies that require bespoke applications, which are custom-built software solutions designed to meet specific business needs, or have unique infrastructural requirements, like hosting massive databases or enterprise applications.
Famous examples of IaaS providers are Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).Platform as a Service (PaaS)
PaaS provides a generic and ready-made platform using which application development can be achieved with the ability to develop, test, and deploy applications without issues of infrastructure to manage.
Companies that are looking to develop new products at a fast pace and are looking to simplify their cloud strategy find relief in the flexibility of PaaS.
Well-known PaaS vendors are Heroku, Microsoft Azure App Services, and Google App Engine.Software as a Service (SaaS)
SaaS offers a complete working software application online, providing users with the convenience of accessing applications via web browsers without the need for installation or internal maintenance.
Application using SaaS is very alluring and can be accessed using almost all devices connected to the internet. It is affordable and requires little investment since it relies on the subscription-based pricing model. Moreover, providers update these services automatically, and the users will always enjoy the latest features and security updates.
Companies that pay much attention to efficiency and comfort also use SaaS to find solutions to such problems as CRM systems, human resource software, or collaboration platforms.
Among the top SaaS providers are such companies as Salesforce, Microsoft 365, and Dropbox.
Real-Life Alteration: The Way of a Retail Enterprise Decision-Making
Bear in mind a retail business that is transforming digitally. It can choose IaaS to place its core ERP system on a safe and expandable cloud framework. At the same time, it also has the potential to build a real-time mobile application, which means an application that provides data and information as it happens, to engage with customers using PaaS. In the case of internal processes, the company may consider using SaaS such as Salesforce in terms of customer relationship management and Slack as a team-based platform.
With the integration of various cloud models, the organization enjoys a balanced direction of control, agility, and efficiency in its operations.

Future Trends in Cloud Adoption
The knowledge of the differences between IaaS, PaaS, and SaaS will put your organization in a good position to leverage the developing cloud trends.
Hybrid clouds are gaining popularity, and enterprises can use the system they have on-premises with both the public and private cloud solutions, so that there is added flexibility. The marriage of AI and machine learning connectivity in cloud systems is also increasing notably in the PaaS and SaaS service offerings. Serverless computing is a development of PaaS and enables the user to write the code, but have the platform scale and run it so that the developer does not have to worry about execution. Furthermore, edge computing is becoming popular, as splitting the distance between data sources and processing achieves results, increasing intensity in applications linked with IoT and real-time usages.
