What are different types of Cloud Deployment Models?
Cloud computing has gained much attention in the recent past due to the following advantages among others. When adopting cloud architecture, there are three different types of cloud deployment models that help deliver cloud computing services: public cloud, private cloud, and hybrid cloud. . In this article, we will discuss these models in detail as follows.
What is a Cloud Deployment Model?
Cloud Deployment Model functions as a virtual computing environment with a deployment architecture that varies depending on the amount of data you want to store and who has access to the infrastructure.

Public Cloud
A public cloud is a type of cloud service model that is available from third party vendors like GCP or AWS. In a public cloud, you don’t have to invest a large sum of money upfront and can simply use the services as and when required and also without the bother of worrying about the expenses. Public clouds are suitable for organizations that need a cheap and scalable model for how they address their computing needs.

Public clouds deliver resources, such as compute, storage, network, develop-and-deploy environments, and applications over the internet. They are owned and run by third-party cloud service providers like Google Cloud.
Advantages of Public Cloud Model
There are lots of benefits that businesses and individuals can accrue from the use of public cloud services. Here are some of the key benefits:
1. Cost Efficiency
- Pay-as-You-Go Model: This is more effective for your company because it costs nothing upfront for hardware and software, and you only pay for what you consume.
- No Maintenance Costs: Previous work outlines how cloud providers take care of maintenance, updates, and other structural concerns.
2. Scalability
- On-Demand Resources: The resources can be easily expand as well as reduced as per the business requirements and the changes in the market.
- Global Reach: Public clouds usually offer infrastructure in a few areas, thus helping businesses to internationalize processes and outcomes smoothly.
3. Flexibility and Accessibility
- Anywhere, Anytime Access: Resources can be obtained at any place with internet connection; hence making work from home and international cooperation possible.
- Wide Range of Services: The services provided by the public cloud are innumerous including computation, storage, database, learning and much more.
4. Reliability
- High Availability: Public clouds generally have good disaster recovery mechanism and redundancy mechanisms that make the uptime high.
- Continuous Monitoring: In many cases, providers track the systems in operation at all times to look for problems that may affect the end users.
5. Security
- Advanced Security Measures: Providers apply industry best practices of security, cryptography, and compliance with widely used standards.
- Regular Updates: Consumers can change their approach to protecting their data by updating the latest measures to counter threats.
6. Innovation and Speed
- Access to Cutting-Edge Technology: Through innovations, public cloud vendors always ensure that business is always up to date with the technological advancements.
- Faster Deployment: Since the resources are just applications and services, they can be implemented immediately without having to wait for the adoption of structures.
7. Collaboration
- Multi-User Environment: Public clouds encourage real-time communication and information access and sharing, internally enhancing the performance of a team.
8. Reduced Environmental Impact
- Efficient Resource Use: Common resources are efficiently utilized, making solutions more efficient by eliminating wastage to on-premise solutions.
9. Ease of Management
- Managed Services: This means that cloud providers rely on themselves to complete everyday responsibilities, including backups, updates, and infrastructure.
Private Cloud
A private cloud, however, is one that is essentially constructed by oneself: one implements a private cloud. This is also known as the private cloud in which you have an ultimate control over the customization of the platform. Private clouds are the most secure of all clouds, but they are also the most costly, and they do not have the flexibility of the other types of cloud since they cannot be easily expanded or contracted. The maintenance rests with you, and there may be connection delays in the future.

Private clouds are built, run, and used by a single organization, typically located on-premises. They provide greater control, customization, and data security but come with similar costs and resource limitations associated with traditional IT environments.
Advantages of Private Cloud Model
Private cloud model come with numerous benefits, especially in situations where the organization has unique requirement on matters to do with security, compliance or performance. Here are the key benefits:
1. Enhanced Security
- Dedicated Resources: Private clouds are not like the public ones, and they are not used by other organizations; therefore, it eliminates some risks.
- Customizable Security Controls: Let us consider special means of security like fire walls, encryption technique, and access control policies to be adopted by the organization.
- Compliance with Regulations: Perfect for organizations as healthcare, finance, and government, which has to provide compliance with some legislations (for example, HIPAA, GDPR).
2. Greater Control
- Full Customization: There existing choices that enable organizations to configure the infrastructure, hardware and or software depend on its needs.
- Data Governance: Data storage can always remain in the company’s control as well as how it is processed and accessed by third parties.
3. Performance Optimization
- High Performance: Resources are not shared with others, this makes it easy and possible to achieve set goals and objectives especially for applications with large jobs to accomplish.
- Low Latency: Compared to the public cloud services, the on-premises or dedicated hosting guarantees low latency.
4. Scalability
- Tailored Scaling: Compared to the public cloud settings private cloud can also dynamically allocate resources for the increasing needs of the business.
- Hybrid Integration: Like public clouds, private clouds can be used in a combination known as hybrid clouds to work loads that have spike in demand.
5. Cost Predictability
- Fixed Costs: Subsequently, once the invocations are known and the basic architecture is deployed, internal private cloud solutions are cheaper than public ones operating with a pay as we go system.
- Long-Term Savings: I reckon that private cloud makes sense for demand predictable large enterprises as it will be cheaper in the long run.
6. Durability & Government Control
- Industry Standards: Private clouds are again favorable for compliance with certain industries’ standards and audits.
- Isolation: Contributes to compliance by maintaining specific information in different areas that are not easily accessible.
7. Reliability
- Controlled Environment: Lesser number of factors that are changeable, and lesser dependence on factors outside the system lead to increased stability.
- Backup and Disaster Recovery: Back up, policies, and programs can be easily tailored to meet the needs of the organization in case of disaster.
8. Improved Customization
- Purpose-Built Infrastructure: Organizations can design their private cloud for specific applications or workloads, optimizing efficiency and performance.
- Integration with Legacy Systems: Easier to integrate with on-premises or older systems compared to public cloud.
9. Support for Critical Applications
- Legacy System Compatibility: Ideal for running applications that are not designed for the public cloud.
- Guaranteed Uptime: Offers higher levels of uptime for mission-critical systems.
10. Privacy
- Data Isolation: Sensitive data is stored and managed entirely within the organization’s controlled environment.
- Reduced Risk of Breaches: Eliminates risks associated with multi-tenancy in public cloud environments.
Hybrid Cloud
Hybrid cloud is that model of cloud which combines elements of both public and private cloud. This model is common when the organizations are in the process of moving from private to public cloud deployment. Hybrid cloud is also employed as a fail-safe in case of an event of an emergency. This model combines the features of both public and private clouds; hence, it provides the cost advantages and flexibility of public cloud and the security and control of private cloud.

Environments that mix at least one private computing environment (traditional IT infrastructure or private cloud, including edge) with one or more public clouds are called hybrid clouds. They allow you to leverage the resources and services from different computing environments and choose which is the most optimal for the workloads.Â
Advantages of Hybrid Cloud Model
Hybrid cloud is the integration of both private and public cloud computing which makes it beneficial to work with the worth getting both environment. Here are the key benefits:
1. Flexibility and Scalability
- On-Demand Scaling: A business can use private cloud for known, continuous workloads and can use public cloud for variable workloads for example during holiday season.
- Resource Optimization: It allows the organization to promptly assign the appropriate resources to the work that is expected to be heavy in demand.
2. Cost Efficiency
- Reduced Costs for Non-Sensitive Data: Some applications can be deployed, for example, to the public cloud which is cheaper in comparison to the private one and the confidential data will still be stored in the private cloud.
- Pay-As-You-Go Model for Public Cloud: Another is its ability to enable customers’ users to access additional public cloud resources at reduced prices when wanted.
3. Enhanced Security
- Sensitive Data in Private Cloud: Large data that is sensitive can be saved securely in the private cloud.
- Controlled Public Cloud Use: Implicit workloads and information that do not require a high level of protection can exist in the public cloud.
4. Improved Business Continuity
- Disaster Recovery: Offers the strengths of public cloud redundancy with the flexibility of controlled private cloud backup for DR.
- High Availability: Offers contingency solutions in private and public domains to avoid disruption of business.
5. Compliance and Regulation
- Regulatory Requirements Met by Private Cloud: Business-critical workloads and data at the same rate that to complies with regulatory needs is capable of residing on-premise, private cloud.
- Leverage Public Cloud for Less Regulated Tasks: Low risk tasks are allowed to be deployed in public cloud because it has limited compliance requirement.
6. Performance Optimization
- Workload Distribution: This means high performance applications are run in the private cloud while low-performance applications are run in the public cloud.
- Low Latency: Allows latency intense workloads to run in private cloud while leveraging the elasticity of a public cloud.
7. Innovation and Speed
- Faster Deployment: New applications can be developed and tested and can be made available immediately in the public cloud.
- Access to Advanced Tools: Competitive tools such as AI, big data analytics may be provided in the public clouds while such activities may not be needed in private cloud operations.
8. Improved Customization
- Purpose-Built Infrastructure: Organizations can design their private cloud for specific applications or workloads, optimizing efficiency and performance.
- Integration with Legacy Systems: Easier to integrate with on-premises or older systems compared to public cloud.
9. Support for Critical Applications
- Legacy System Compatibility: Ideal for running applications that are not designed for the public cloud.
- Guaranteed Uptime: Offers higher levels of uptime for mission-critical systems.
10. Privacy
- Data Isolation: Sensitive data is stored and managed entirely within the organization’s controlled environment.
- Reduced Risk of Breaches: Eliminates risks associated with multi-tenancy in public cloud environments.
