TYPES OF CLOUD COMPUTING

Cloud computing is a comprehensive term that directs to services that enable businesses to expand their IT capacity and functionality at a low cost. Companies can choose where, when, and how they use cloud computing to ensure an efficient and reliable IT solution based on their specific requirements.

 The following sections discuss the various types of cloud computing, including the three primary deployment models and the cloud services hosted within them.

Cloud Deployment Models

There are 3 main classes of cloud environments, also known as cloud deployment models. Businesses can run applications on public, private, or hybrid clouds depending on their specific needs.

Public Cloud

A public cloud environment is possessed by an outsourced cloud provider and is available via the internet to many businesses on a pay-per-use basis. This deployment model delivers services and infrastructure to companies looking to reduce their IT operational costs, but the cloud provider is ultimately responsible for resource creation and maintenance.

Public clouds are ideal for small and medium-sized businesses operating on a shoestring budget and needing a simple platform for deploying IT resources.

Advantages of a Public Cloud

• Scalability is simple.
• There are no geographical limitations.
• Budget-friendly
• Exceptionally reliable
• Simple to use

Private Cloud

This cloud deployment model entails a single business owning its bespoke infrastructure. It provides a more controlled environment with more centralized access to IT resources within the company. This model can be hosted externally or managed in-house. Although private cloud hosting is more expensive, it can provide a higher level of security and the ability for larger businesses to tailor the storage, networking, and compute components to their specific IT requirements.

Pros of a private cloud

• Increased security
• Enhanced server control
• Highly customizable

Hybrid Cloud

A hybrid cloud environment is an excellent choice for businesses seeking the benefits of both private and public cloud deployment models. A hybrid cloud model combines the two models to create a more tailored IT solution that meets specific business requirements.

Advantages of a hybrid cloud

• Highly adaptable and scalable
• Reasonably priced
• improved security

Cloud Services

Cloud computing service models are divided into three categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). There are apparent differences between the three regarding what they can present to a business regarding storage and resource pooling, but they can also interact to form a single comprehensive cloud computing model.

• IaaS (Infrastructure as Service)

The most common cloud computing service model provides virtual servers, networks, operating systems, and data storage drives. It gives the cloud flexibility, reliability, and scalability while eliminating the need for office hardware. This makes it ideal for SMBs looking for a low-cost IT solution to support business growth. It is available as a public, private, or hybrid infrastructure.

• PaaS (Platform-as-a-Service)

But businesses can develop and run their applications using cloud computing infrastructure and software frameworks. PaaS makes it simple to build web applications and is flexible and robust enough to support them. Sourcing PaaS solutions are ideal for businesses that need to share development resources. It can also leverage an existing data source (like a CRM tool).

• SaaS (Software as a Service)

This cloud computing solution involves distributing software over the internet to businesses that pay per use or subscription. It’s excellent for CRM and apps that require a lot of web or mobile access, like mobile sales management software. SaaS is managed centrally, making it ideal for short-term projects.
