Types of Cloud Computing and Cloud Services

One of the terms used most frequently in information technology nowadays is cloud computing. The term cloud computing refers to the delivery of IT resources on the demand of users.

We can store the files in different remote locations by utilizing cloud computing, providing us with security, scalability, abstraction, etc. In simple terms, cloud service providers manage the servers and storage devices as they have high-quality devices and maintenance teams and provide the IT resources to organizations or individual users according to their requirements.

Types of Cloud Computing

Public Cloud

Public clouds are cloud environments generally created by third parties not owned by the end user. Public clouds are open to all the public to store, access, and manipulate data over the internet.

The cloud service provider manages and operates its resources. Some of the largest cloud providers include the Google cloud platform(GCP), Amazon Web Services(AWS), Microsoft Azure, IBM Cloud, and Alibaba Cloud.

Private Cloud

A private cloud offers software services to a private internal network, typically within a company or particular individuals, instead of being publicly accessible. Any location or ownership rules are now irrelevant because businesses are already establishing private clouds on rented, vendor-owned data centers that are off-site.

We can create a private cloud in two different ways. The standard strategy is to have their infrastructure set up for private networks or intranets. Organizations like Infosys, Wipro, and other conventional service-based businesses adopt this method.

A VPC (Virtual Private Cloud) is the second possibility (VPC). In this scenario, they still have a private cloud, but with the aid of cloud service providers, it is reachable via the open Internet. A company will employ a private cloud in this instance to host its website, with no resources having any public IPs issued. Employees will use a VPN to access the website.

Hybrid Cloud

A hybrid cloud is an IT environment comprising several environments that appear to be connected by LANs, WANs, VPNs, or APIs to form a single, unified environment. You should be able to link many machines and combine IT assets using hybrid clouds. Finance, healthcare, and higher education are three industries that mostly use hybrid clouds.

However, when apps may move in and out of many distinct yet connected environments, every IT system turns into a hybrid cloud. These environments must be derived from centralized IT resources that can scale as needed, at the very least. And a platform for integrated management and orchestration must be used to manage each of those environments as a single environment.

Multi-Clouds

Multi-cloud enables information sharing between an organization and a particular community by allowing several organizations to access the systems and services. One or more local nonprofits, a third party, or a combination of them all own, administer, and run it.

Multi clouds are generally used in media, healthcare, and scientific industries. An environment with multi-clouds may exist accidentally or on purpose (to better protect sensitive data or provide redundant storage for improved disaster recovery) (usually the result of shadow IT).

Types of Cloud Services

Infrastructure as a Service (IaaS)

Infrastructure as a Service (IaaS) is a cloud computing service where enterprises rent or lease servers for computing and storage in the cloud. Users can run any OS (operating system) or application on rented servers without worrying about the server's upkeep and running costs.

IaaS provides compute storage, network, and load balancer services. IaaS provides shared infrastructure, web access to the resources, a pay-as-per-use model, and on-demand scalability.

Platform as a Service (PaaS)

PaaS refers to an external cloud service provider providing and managing the hardware and an application-software platform. Still, the user is in charge of the apps that run on top of the platform, and the data such apps rely on. It makes it simple for programmers to build, test, use, and deploy web apps.

PaaS provides different programming languages, application frameworks, databases, and other tools. PaaS provides simplified development, lower risks, pre-built business functionalities, and scalability.

Software as a Service (SaaS)

SaaS is a service that offers consumers access to a managed software program hosted in the cloud. Most SaaS apps are web or mobile applications that consumers can access through a web browser. The user connects to the cloud applications through a dashboard or API, and software upgrades, bug fixes, and other general software maintenance are taken care of for them.

SaaS provides business services, document management, social networks, and mail services. SaaS is easy to buy, has fewer hardware requirements, has low maintenance, multi-device support.
