Which cloud service model is best suited for a start-up that needs storage and additional computing power, while being scalable?

Choosing IaaS, or Infrastructure as a Service, is particularly advantageous for a start-up needing both storage and additional computing power with scalability in mind. IaaS provides virtualized computing resources over the internet, offering the foundational infrastructure (such as servers, storage, and networking) that a start-up can dynamically scale as its requirements grow.

This means that your start-up can start small, paying only for the resources it uses, and can easily increase capacity as needed without investing in physical hardware. This flexibility is crucial for startups that often experience unpredictable growth patterns and need accommodating solutions.

In contrast, while PaaS (Platform as a Service) provides a platform allowing developers to build, deploy, and manage applications without worrying about the underlying infrastructure, it may not offer the level of raw storage and computational flexibility a start-up might require as its needs evolve. SaaS (Software as a Service) delivers software applications over the cloud but does not provide underlying infrastructure or storage for custom applications. BPaaS (Business Process as a Service) is more focused on outsourcing specific business processes rather than delivering extensive computing resources, making it less relevant in the context of infrastructure needs. Hence, IaaS is the most suitable option for a start-up seeking scalability
