IaaS, PaaS, and SaaS, which stand for infrastructure as a service, platform as a service, and software as a service, respectively, are the three primary types of cloud computing. The most fundamental of them is IaaS. The phrase “aaS” refers to a shared, hourly, or monthly billing, contractless, and self-service type of service, whereas the keyword “infrastructure” is related to computing, storage, and networking. The cloud infrastructure that providers and suppliers refer to as data centres. Customers of IaaS can lease space from the virtual data centre and use the internet to access these cloud infrastructures. You will learn about the cloud infrastructure, its benefits and drawbacks, as well as some related facts, in this post.

Cloud Infrastructure of IaaS

1. Compute

In terms of computing, IaaS refers to a virtual machine in the cloud that is located anywhere on the servers of the service provider rather than being on a fixed piece of hardware. GPUs and CPUs are frequently employed in IaaS, and they are used for many kinds of workloads. In order for consumers to receive the appropriate quantity of computation based on a pay-for-what-you-use model, the providers are controlling the hypervisors. 

2. Storage

Objects, files, and blocks are the types of data that cloud storage is intended for. The most popular among them is object storage since it offers many advantages, including security, adaptability, and scalability for massive amounts of unstructured data. Music, image, and video files are examples of unstructured data. Through APIs or HTTP/HTTPS, we can easily access them. The storage volume has a fixed-sized capacity and is considered as an individual disc drive for block storage. The user can store, back up, restore, and recover data whenever necessary thanks to the cloud infrastructure of IaaS.

3. Networking

Traditional networking hardware, such routers and switches, is now programmatically accessible thanks to API. Additionally, we refer to software defined networking as the networking done on the cloud. Additionally, there are forms of more sophisticated networking, such the creation of multi-zone regions and virtual private clouds, which will be covered in more detail in forthcoming sections.
