In this article, we define cloud computing, describe several cloud deployment models, the best way to learn cloud computing, and the benefits and drawbacks of cloud computing services.

What is Cloud Computing? 

Cloud computing is a technology that allows businesses to access, manage and update their data via the internet. This simplifies operations and enables employees to access corporate resources from different locations and devices. Cloud computing provides greater flexibility and scalability in IT infrastructure, making it a popular choice for businesses. All data is accessible online, whether you’re working on a phone while traveling or a laptop while staying in a hotel outside your country. Cloud computing can be a more cost-effective option for organizations that deal with large or complex data volumes, as it eliminates the need for expensive on-premises infrastructure and hardware maintenance.

Together with software, servers, networks, and databases, clouds may offer a wide range of other services in a virtual setting. To free up space, cloud computing can be employed in place of or in addition to conventional servers.

What are the Different Types of Cloud Computing Services? 

Cloud computing offers limitless opportunities, with various models and deployment techniques available to meet different user demands. The specific cloud computing service a company chooses determines the level of control they have over their cloud usage. There are several types of cloud computing services available, which allow organizations to regulate different aspects of their cloud usage to varying degrees. These services include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and Function as a Service (FaaS), each offering unique benefits and levels of control. The top four cloud computing service categories are as follows:

Infrastructure as a service (IaaS)

Infrastructure as a service (IaaS) is a cloud computing model that offers greater flexibility and customization. It is suitable for businesses that already have their own operating systems but require tools to manage them in the future. With IaaS, companies can lease and manage servers, networks, and operating systems that make up the core IT infrastructure underlying cloud services. Various IaaS services and components are available online for businesses to use.

IaaS is an excellent option for startups seeking to avoid the time-consuming and costly process of building on-premises IT infrastructure. Large organizations can also use this approach if they want to maintain control over their IT infrastructure while having the option to pay only for the resources they use. Some common examples of IaaS are AWS (Amazon Web Services), Rackspace, Azure (Microsoft), and Alibaba Cloud.

Platform as a service (PaaS)

Platform as a Service (PaaS) is a cloud computing model that enables businesses to build, test, maintain and debug applications in a cloud environment. PaaS offers a set of building blocks for software development, allowing enterprises to focus on application development while the vendor takes care of infrastructure, security, and data integration. PaaS services are provided by third-party cloud providers, who host the hardware, software, and other elements of the underlying cloud architecture. PaaS is commonly used by coding experts to design, modify, and test new computer systems quickly. In a Rapid Application Development (RAD) environment, PaaS can significantly reduce expenses and streamline the application development lifecycle. Apache Stratos, Google App Engine, Amazon Elastic Beanstalk, OpenShift, and Heroku are popular PaaS examples.

Software as a service (SaaS)

Software as a service (SaaS) is the most common type of cloud computing used by businesses today. With SaaS, companies obtain their computing resources from a third-party provider who maintains the infrastructure, system upgrades, software and hardware. SaaS offers complete, user-ready applications over the internet, allowing businesses to save time that would have been spent on software downloads and installation. Customers pay a license fee to use the cloud provider’s services and can access SaaS through a computer, mobile device, or software program that permits the usage of cloud services.

Startups can leverage the SaaS model to quickly launch corporate applications without worrying about server and software setup. Popular examples of SaaS include Dropbox, Cisco Webex, Google GSuite (applications), and GoToMeeting. By utilizing SaaS, businesses can benefit from cost savings, convenience, and scalability.

Functions as a Service (FaaS)

The idea of serverless computing is known as FaaS. FaaS is a category of cloud computing service that enables you to run code in response to a situation without the complicated infrastructure usually needed to create and run microservices applications. In order to totally isolate developers from everything in the stack below their code, Functions as a Service (FaaS) provides an additional layer of abstraction to PaaS. They upload confined bits of code and set them to be activated by a certain event rather than dealing with the headaches of virtual servers, containers, and application runtimes. Applications that employ FaaS don’t use any IaaS resources until an incident occurs, which lowers pay-per-use costs.

Some well-known examples of FaaS are IBM Cloud Functions, Google Cloud Functions, Amazon’s AWS Lambda, and Microsoft Azure Functions (open source).

What are the Types of Deployment Models in Cloud Computing? 

Employers of cloud computing services decide on the cloud’s design or structure based on what will best serve their requirements. Based on ownership, access, scale, the nature of the cloud, and its intended use, the cloud deployment model determines the particular sort of cloud environment. It details the design of your cloud infrastructure, what you may modify, and if you will receive services or must develop everything from scratch.

The 4 primary categories of cloud computing deployment systems are as follows:

Public cloud 

A public cloud is a type of cloud computing that is managed by a third-party cloud provider, who provides cloud services to their customers through the public internet. This type of cloud infrastructure is accessible to anyone, and the cloud provider is responsible for the ownership, control, and maintenance of the cloud storage, hardware, architecture, and assets. The data and applications that are stored in the cloud belong to the customers who use the service.

 

Public clouds are often the most cost-effective type of cloud deployment as they provide shared resources to multiple customers. However, as it is available to all users, the public cloud may be less secure. Storage backup and retrieval services are typically provided for free, through a subscription, or on a per-user basis. Popular public cloud examples include Google App Engine, Amazon Web Services, and Microsoft Azure.

Private cloud 

Private cloud is a deployment strategy that provides cloud computing resources exclusively for one person or company. Unlike public clouds, private clouds offer more granular control and flexibility over cloud resources. The users can access private cloud services over a private network that is not accessible to the general public on the internet. Third-party cloud service providers can offer private cloud options, but they come with a higher cost than public clouds. Companies and academic institutions can also host private clouds for their exclusive use. Private cloud deployment is often chosen by businesses with strict data security requirements, regulatory compliance needs, or specialized workloads that require dedicated resources.

 

The cloud platform is put into use in a highly secure, cloud-based environment that is guarded by robust firewalls and under the direction of an organization’s IT department. Private clouds can provide enterprises with more safety than a public cloud since they don’t share their services with many clients through the internet. The cost of a private cloud is often higher than that of a public cloud.

Hybrid cloud 

Services from both public and private clouds are combined in a hybrid cloud. Hybrid cloud computing provides the best of both worlds by linking the public and private realms with a layer of proprietary software. Organizations may often mix different components from both types of clouds while utilising a hybrid cloud. This kind of cloud deployment allows businesses more options in their infrastructure and operations since hybrid clouds may often be customized by firms.

Depending on their needs, organisations might use a mix of two or more cloud deployment methods to move data and applications between various clouds. Without forcing them to give up their current infrastructure, compliance, or cybersecurity, this increases enterprises’ flexibility.

Multi Cloud 

A multi-cloud system refers to a setup in which a company uses several cloud service providers, similar to a hybrid cloud deployment strategy that combines resources from public and private clouds. Multi-cloud systems can help businesses manage independent clouds for different workflows, departments, or branches, and improve their cybersecurity. However, managing multiple clouds can be challenging since resources may not be easily exchangeable between distinct infrastructures. Despite these challenges, multi-cloud systems offer greater flexibility, reduce vendor lock-in, and optimize cost and performance by leveraging the strengths of different cloud service providers.

 

The Pros and Cons of Each Type of Cloud Computing 

 

Cloud Computing	Pros	Cons
Public Cloud	Little Investment since it is a pay-per-use service, there is no large upfront cost.	Because public cloud resources are shared, there is no assurance of high-level security.
	As the cloud service providers totally fund the whole infrastructure, there is no setup cost.	Since many people have access to it, it cannot be altered to suit individual needs.
	The service provider does the maintenance work.
	To satisfy your company’s needs, resources are available on demand.
Private Cloud	Greater Control because you are the property’s lone owner.	Because there are fewer clients, private clouds can only scale to a certain extent.
	Since only authorized staff members have access to company information, there are no issues when it comes to access and security.	Private clouds are more expensive because they offer specialized features.
	This approach is designed to work with outdated hardware that is unable to connect to the cloud.
	A private cloud deployment provides businesses with the ability to tailor their solution to meet their specific needs, unlike a public cloud deployment. This level of customization offers organizations greater control and flexibility over their cloud resources.
Hybrid Cloud	Companies with greater flexibility are able to create solutions that are unique to their requirements.	As a blend of both public and private clouds, it is challenging to maintain hybrid clouds.
	You will only be obligated to pay for additional capacity if you actually need it because public clouds provide for scalability.	With the hybrid cloud, latency is a result of the public cloud being used for data transmission.
	Data separation techniques have significantly decreased the likelihood of data theft by attackers.
Multi Cloud	By utilising many cloud providers, you may combine and match the finest elements of their offerings to meet the needs of your apps, and company.	Many clouds combine to make the system complicated, and bottlenecks may develop.
	You may select cloud zones and locations that are close to your clients to decrease latency and enhance user experience.	The data is vulnerable because of the complicated structure’s potential for flaws that a hacker may exploit.
	High level of service availability.
