NexQloud Knowledge Base

The service model determines the level of abstraction and management you are responsible for, moving from physical infrastructure to complete software applications.

• Infrastructure as a Service (IaaS): This is the foundational layer. With IaaS, you rent fundamental IT infrastructure—servers, networks, and storage—on a pay-as-you-go basis. Nexqloud's IaaS gives you direct control over the operating systems and applications while we manage the underlying hardware. It's like leasing a plot of land and building your own house; you have full control over the construction, but don't worry about maintaining the land.
• Platform as a Service (PaaS): PaaS builds on IaaS by providing a complete development and deployment environment in the cloud. Nexqloud's PaaS solutions manage the underlying infrastructure, operating systems, and middleware, allowing your developers to focus solely on writing and managing code. Think of it as moving into a fully-equipped workshop; you can build anything without worrying about tool maintenance or electricity.
• Software as a Service (SaaS): SaaS delivers fully functional, ready-to-use applications over the internet. With SaaS, the provider (like Nexqloud for certain applications) manages everything from the infrastructure to the application itself. You simply access the software via a web browser. Common examples include email, customer relationship management (CRM), and collaboration tools. This is like subscribing to a streaming service—you just enjoy the content without managing the servers.
• Serverless Computing (Function-as-a-Service): Serverless is an even higher level of abstraction. You simply write and deploy individual blocks of code (functions) that run in response to events. Nexqloud's serverless platform automatically handles all the provisioning, scaling, and management of the infrastructure. You only pay for the compute time your code consumes, making it highly efficient for event-driven tasks like data processing or API backends.
