Cloud Deployment Models
There are 3 types of cloud computing: public, private, hybrid. Let’s discuss what is public, private, and hybrid cloud computing.
Cloud service providers own and operate public clouds over the internet. The public cloud allows cloud tenants to share infrastructure, storage, and network devices. You use a web browser to access services and manage your account.
Advantages of Public Cloud
- There is no need for capital investments, expensive equipment, or extra space.
- You only pay for what you use, allowing you to scale up or down to get the computing power you need.
- You spend less time managing a data center and can put more effort into more money-making tasks.
- It offers automated, scalable disaster recovery services for improved business performance and compliance
- Public cloud hosting solutions are universal and useful to enterprises in numerous industries.
Disadvantages of Public Cloud
- The public cloud’s shared resources nature increases the risk of data loss and breaches.
- You put your data in the cloud service provider’s system and relinquish control over the critical IT infrastructure.
- For a company that needs a customized cloud solution, this architecture won’t work.
A private cloud is exclusive to one company. Businesses get dedicated servers to fulfill their company’s computing needs via an encrypted private network. The data center resources can be on-site or managed by a third party.
Advantages of Private Cloud
- Private Cloud is an exclusive, dedicated environment just for you and is inaccessible to other groups.
- Private Cloud has exceptional efficiency and dependability, making it a top choice for business needs.
- It’s flexible, and its infrastructure can be changed to meet an organization’s growing needs.
- It’s secure. You can create protocol runs, configurations, and protections based on the company’s workload requirements to keep data safe and secure in the private cloud.
- It is moderately scalable and meets unanticipated demands without compromising security or performance; adding more users or resources doesn’t call for significant changes to the current setup.
Disadvantages of Private Cloud
- Due to security precautions, mobile users may have limited access to the private cloud.
- A private cloud solution’s upfront and ongoing costs are far higher than public cloud alternatives.
- On-site infrastructure may have limited scalability options to meet all needs.
A hybrid cloud comprises public, private, and on-premises infrastructure, providing a mixed environment for computing, storage, and networking services.
Businesses often choose the hybrid cloud approach for three reasons:
- To get the most out of their on-premises technology investments
- To deal with low latency issues,
- To meet regulatory and data sovereignty requirements.
Advantages of Hybrid Cloud
- Remote and distant employees can access data on demand with a hybrid cloud.
- Hybrid cloud models optimize IT performance, provide business agility, and speed up market time.
- Business continuity is improved, lowering the likelihood of potential downtime and associated costs.
- It’s ideal for firms that want more data security and control but need a cost-effective way to scale operations.
- It allows organizations more data control and scalability, letting them adjust workloads as business and IT service demands change.
Disadvantages of Hybrid Cloud
- Cloud environments are complex, and you might violate compliance rules if you’re not careful.
- Hybrid cloud usage by third-party providers puts your organization in danger of cyberattacks on its central server.
- A hybrid cloud is expensive due to the investment, maintenance, and skill required for on-premises hardware and private cloud components.
A community cloud is a computing infrastructure that facilitates data sharing across multiple entities. It can be owned and operated by a community organization, a third party, or both.
Advantages of Community Cloud
- Customers can choose their data protection preferences.
- Organizations share cloud computing resources, saving them money.
- The community cloud is flexible, scalable, and works for every user.
- All cloud-based assets, including infrastructure and services, can be pooled and shared among businesses.
- The IT department will have less to do since the data, apps, and systems are in the cloud and thus need less management.
Disadvantages of Community Cloud
- The adoption of data is very slow.
- It is hard for organizations to share responsibilities.
- The cost of a Community Cloud is higher than that of the public cloud.

Cloud Computing Service Models
The 3 main cloud computing models are Infrastructure as a Service, Platform as a Service, and Software as a Service. They help you employ infrastructure, scale your business, and improve manageability.
The three cloud computing models support business activities by reducing capital requirements, providing on-demand access, and lowering IT costs.
IaaS (Infrastructure as a Service)
Infrastructure as a Service helps you reduce the expense of hardware upgrades to your data center and obtain real-time business insights. You can quickly scale the resources allocated to your IT infrastructure based on your needs.
IaaS aids in the speedy provisioning of new apps and improving the reliability of the underlying infrastructure. It’s typically best for on-premises workloads, such as backup and recovery, dev and test environments, customer-facing websites and web apps, storage systems, analytics, and data warehousing.
PaaS (Platform as a Service)
PaaS helps developers and businesses build great apps without worrying about infrastructure and operating systems. It reduces the effort required to assess, purchase, set up, and manage all the hardware and software for custom-built apps.
Startups and small enterprises widely use paaS due to its inexpensive, upfront costs, which gives them equal access to cutting-edge tools as their larger counterparts. It also frees businesses to focus on their core competencies without being distracted by routine administrative tasks.
SaaS (Software as a Service)
SaaS is beneficial for HR and other enterprise-level support functions. These jobs need employees from different departments to collaborate remotely to share, edit, and publish content.
