The underlying hardware and software elements that underpin cloud computing services are referred to as infrastructure in this context. In addition to the virtualized resources like operating systems, containers, and virtual machines, it also covers the physical resources like servers, storage devices, networking hardware, and data centers.
A cloud service provider, such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP), often offers infrastructure in cloud computing. These cloud service providers give access to and management of a variety of infrastructure services over the internet, negating the need for businesses to purchase or maintain physical infrastructure.
The three tiers of cloud computing infrastructure are as follows:
1. Infrastructure as a Service (IaaS): IaaS gives businesses access to virtualized computer resources like networking, storage, and virtual machines. These tools can be used by businesses to operate current apps on the cloud or create new ones.
2. Framework as a Service (PaaS): PaaS offers businesses a framework for creating, testing, and deploying cloud-based applications. A variety of pre-configured software elements and tools that can be used to create and deploy applications are often included with PaaS services.
3. Software as a Service (SaaS): SaaS offers internet-based access to pre-built software and applications for use by businesses. SaaS programs can be accessible from any device with an internet connection and are often provided on a subscription basis.
Organizations can use computing resources on demand, scale them up or down as needed, and only pay for what they really use thanks to cloud computing infrastructure. Compared to conventional on-premises infrastructure, this gives enterprises a more adaptable, agile, and economical option to develop and operate IT infrastructure.
