The Cloud and Cloud Computing
The term “cloud” refers to a worldwide network of servers, each with a specific function. The cloud is not a simple concept, but rather a complex web of remote servers located all over the world that are linked together and intended to function as a single ecosystem.
These servers are intended to store and manage data, run applications, or provide content or services such as streaming videos, webmail, office productivity software, or social media. Instead of accessing files and data from a local or personal computer, you access them online from any Internet-capable device—the information is accessible wherever you go and whenever you need it.
Cloud computing is being used by businesses of all sizes, types, and industries for a wide range of applications, including data backup, disaster recovery, email, virtual desktops, software design, and testing, big data analytics, and consumer web applications.
Healthcare organizations, for example, are utilizing the cloud to develop more personalized treatments for patients. Financial services organizations are using the cloud to fuel real-time fraud prevention and detection. In addition, video game developers are utilizing the cloud to deliver games online to millions of players worldwide.

Types of Cloud Computing
There are three main types of cloud computing. Let us discuss them in brief.
Infrastructure as a Service (IaaS)
The fundamental components of cloud computing, also known as IaaS, include access to networking capabilities, machines (virtual or on dedicated hardware), and digital storage space. With the most flexibility and management control over your IT resources, Infrastructure as a Service is comparable to the current IT resources that many IT departments and developers are accustomed to today.
Platform as a Service (PaaS)
Platforms as a Service allow you to concentrate on the deployment and administration of your applications by removing the need for companies to manage the underlying infrastructure (often hardware and operating systems). As a result, you can run your application more efficiently as you won’t have to deal with things like resource acquisition, capacity planning, software maintenance, patching, or any other undifferentiated heavy lifting.
Software as a Service (SaaS)
The service provider delivers and manages a final product via Software as a Service. Software as a service is also known as end-user applications. When employing a SaaS solution, you just need to think about how you’ll use the software; you don’t need to think about how the service will be maintained or how the fundamental infrastructure will be managed.
Understanding Cloud Deployment Model
A cloud deployment model denotes a specific cloud environment depending on who manages security, who has access to resources, and whether they are shared or dedicated.
It describes the look of your cloud infrastructure, the extent to where you can modify it, and whether you will be provided with services. Cloud deployment types also reflect the connections between your infrastructure and your users.
You should choose the model that best matches your institution’s methodology because each cloud deployment model may satisfy a distinct set of organizational requirements,
In terms of cloud deployment models, there are several options. Your cloud infrastructure and workload allocation are determined by your business requirements. Each cloud deployment approach has advantages and disadvantages. As a result, a thorough grasp of each deployment methodology is required.

Types of Cloud Deployment Models
Now, when we have already got to know about what cloud deployment models are, it’s time to get to the types of deployment models. There are four different types of deployment models. They are:
- Public Cloud
- Private Cloud
- Hybrid Model Cloud
- Community Model Cloud
We’ll discuss them in detail now.
Public Cloud
Public cloud installations are hosted on public servers that are accessible through the internet or a VPN provider. Every day, we use a variety of public cloud services. The service owner bought all hardware, including VM hosts and network equipment. The service owner is often in charge of maintaining and administering all accessible resources. This makes running IT infrastructure significantly less onerous for businesses that do not wish to spend heavily on hardware and software.
Another benefit of this deployment is that there is no need to engage additional people to manage and repair components because the service owner handles everything. On popular public cloud systems that must be able to spin up additional services and capacity fast, the provisioning process is also optimized. Another advantage is that you may reduce your overheads when demand is low, which can save your company money.
However, there are a few downsides too. Many corporations are concerned about privacy and data segregation. If your company works in a field or industry that requires certification, having your data stored on a public server that also shares resources with other organizations may prevent you from using these services. The speed of your organization’s internet connection will be a major consideration, so if you have end users or services that need to connect to that service, you must confirm what the minimum connection speed is for the service that you choose.
Pros of Public Cloud
The certain pros of public cloud are:
- Public Cloud is easily manageable. The great thing about having a managed service is that there is very little maintenance for you and your team to complete. The setup is taken care of, and there is no need to create your own tools because this is also taken care of.
- Because of the way services are invoiced, you do not pay for products that you do not utilize. You may pay more when you require more resources, then scale back when things return to normal.
- Primarily organizations are most concerned with uptime. When your systems fail, your business suffers. Many of these cloud service companies have excellent uptime and service availability.
Cons of Public Cloud
The certain cons of public cloud are:
- There is less control. You do not have access to the systems that host your business apps. If a public cloud platform fails, you do not have access to maintain continuity, as you would in a typical server room or data center setting.
- To prevent cross-contamination between customers utilizing the same hardware on a public cloud, segmentation must be performed to the greatest quality.
- Most businesses have distinct needs for customized services. Many cloud platforms provide just basic functionality with little to no customization options.

Private Cloud
Although there are variations in access between public and private cloud systems, there isn’t much to distinguish the two, beneath the hood. The technological foundations are very similar, but ownership is the essential difference.You will be unable to utilize a private cloud’s services unless you are permitted to log in and use them.
A corporation may opt to host its cloud infrastructure on-premises or in a data center. In any instance, the infrastructure is generally owned by the corporation. The systems that run on a private cloud are created and managed in-house by the firm.
This implies that the firm that operates a private cloud must have technical people on hand to assist with any difficulties that arise during the private cloud’s functioning. Only authorized users have access to the private cloud’s resources, which are rigorously managed.
The ability to integrate cloud services into your organization’s infrastructure is a wonderful feature of this sort of cloud platform.
Pros of Private Cloud
Here are some of the perks of Private Cloud:
- Fewer individuals will be able to administer and configure the back-end infrastructure that supports your private cloud, giving you more control.
- If a new feature has a business case, you may have it created and delivered in-house, providing you with more alternatives than a publicly available cloud.
- To protect your cloud, you may use as many security services as you wish. Two-factor authentication is substantially safer when combined with security best practises such as tough passwords and mandatory password changes.
Cons of Private Cloud
Here are certain disadvantages of Private Cloud:
- You need the appropriate technical abilities to benefit from being able to customize your private cloud. You must fill the responsibilities of developers, cyber security specialists, and DevOps specialists to successfully construct a solution on your private cloud.
- The majority of businesses, excluding the biggest ones in the world, can afford to build their private cloud infrastructure. The hardware expenditures alone are excessively costly for most enterprises.This type of cloud deployment is intended for large enterprises rather than Small and Midsized Businesses(SMBs).
Community Cloud
A community cloud is essentially a multi-tenant hosting platform that frequently includes organizations from related industries and complementary ones with similar objectives using the same infrastructure. Community cloud deployments allow their users to save money by splitting the cost of the infrastructure across several businesses. Except for areas where shared access is agreed upon and set up, data is still segmented and kept private.
The two key advantages are increased potential for real-time collaboration over the same infrastructure and shared costs. They heavily rely on effective tenant collaboration because standardization of best practices will help to strengthen the overall security and effectiveness of these arrangements.
Pros of Community Cloud
Here are certain advantages of Community Cloud:
- The primary advantage of employing this system is the cost savings. This is because everyone who uses the community cloud will split the expenses to ensure a fair experience.
- The community cloud concept is particularly secure if the security guidelines are uniform and if everyone adheres to the same standards.
- When everyone is working toward the same objectives, there are more opportunities to collaborate when everyone is on the same platform.
Cons of Community Cloud
Here are certain disadvantages of Community Cloud:
- A set of standards must be decided upon by a community cloud, which must then coordinate among itself. This implies that each stakeholder needs to have access to their technical resources to implement the policies.
- It is challenging to maintain security and segmentation.
- Because this methodology is not yet extensively adopted, there are not many resources or well-known instances available for others to learn from.
Hybrid Cloud
A hybrid cloud is a cloud platform infrastructure that combines private cloud services hosted on-premises with public cloud services provided by third parties, orchestrating various platforms. Typically, this entails connecting a public cloud to an on-premises data center. Other private assets, such as edge devices or other clouds, may also be connected.
A hybrid cloud approach allows businesses to run workloads in both private and public clouds, switching between the two when computing requirements and prices vary. As a result, a corporation has more alternatives for deploying data and more flexibility. An application’s network, hosting, and web service components are all included in a hybrid cloud workload.
Pros of Hybrid Cloud
Here are some advantages of Hybrid Cloud:
- The flexibility of this cloud type is one of its significant elements. You can choose from each cloud type’s top features and include them in your solution.
- You are not bound by the restrictions of any one platform. This implies that you can adjust your scale based on consumer demand.
Cons of Hybrid Cloud
Here are some disadvantages of Hybrid Cloud:
- You are at risk of going overboard with your expenses if you use a hybrid cloud. Compared to the other cloud types we have examined, hybrid clouds are not intrinsically more costly. However, if you are careless in your choice of the appropriate services, there is undoubtedly a chance of overspending.
- Ensuring that all of your data has been appropriately divided is important, if you combine public and private services. Your company may need to make more security, compliance, and auditing requirements as a result.
