Cloud Computing: Principles, Characteristics, 4 Cloud Deployment Models

Hello Everyone,

Have you ever played a game on your mom's phone or tablet?

Sometimes those games need a lot of memory and space to work, right?

But what if your mom's phone doesn't have enough memory or space for the game? That's where cloud computing comes in.

Think of cloud computing as a giant computer that has a lot of memory and space that you can use for your game or other things you want to do on your mom's phone. When you play the game, some of the parts of the game are stored on the giant computer, so your mom's phone doesn't have to store all of it. It's like the game is borrowing memory and space from the giant computer in the cloud.

Now, let's say your friend wants to play the same game, but he doesn't have a phone or tablet. He can still play the game using his mom's computer because the game is stored in the giant computer in the cloud, not on your mom's phone or your friend's computer.

That's what cloud computing is - using a big computer in the cloud to store and share things like games, pictures, or other important stuff. It's like having a really big backpack that you can use to store all your things and take them with you wherever you go!

What is Cloud Computing?

Cloud computing is a technology that allows users to access and use computing resources, such as servers, storage, applications, and services, over the internet or other wide area networks, without the need for on-premises infrastructure.

Cloud Computing Principle

1. Cloud federation: Cloud federation is the principle of interconnecting multiple clouds to create a single, more powerful cloud environment. This enables organizations to access a larger pool of resources and services across multiple cloud providers, while still maintaining control and security over their data and applications.

2. Cloud independence: Cloud independence is the principle of being able to switch between cloud providers or move applications and data between different clouds without being locked into a specific cloud provider. This ensures that organizations have the flexibility and choice to choose the best cloud provider for their needs, without being tied to a specific vendor.

3. Cloud isolation: Cloud isolation is the principle of ensuring that each customer's data and applications are separated and protected from other customers in a multi-tenant cloud environment. This helps to prevent data breaches and ensures that each customer's data is kept private and secure.

4. Cloud elasticity: Cloud elasticity is the principle of being able to quickly and easily scale computing resources up or down based on changing demand. This enables organizations to respond quickly to changing business needs and to only pay for the resources they use.

5. Cloud trust: Cloud trust is the principle of building trust between cloud providers and customers by ensuring that cloud providers have robust security and compliance measures in place and that customers have visibility and control over their data and applications in the cloud.

6. Business orientation: Cloud business orientation is the principle of aligning cloud computing resources and services with business needs and objectives. This involves understanding the specific needs of each organization and designing cloud solutions that enable them to achieve their goals and remain competitive in their industry.

Cloud Characteristics

Cloud characteristics are the features and attributes that define cloud computing as a technology and delivery model. Cloud computing has several key characteristics that distinguish it from traditional IT infrastructure. These include:

1. On-demand self-service: Cloud computing enables users to provision computing resources, such as servers, storage, and applications, on-demand without requiring human intervention from the cloud service provider.

2. Broad network access: Cloud computing resources can be accessed over the internet or other wide area networks from a variety of devices, including desktops, laptops, tablets, and smartphones.

3. Resource pooling: Cloud computing providers pool resources, such as servers and storage, to serve multiple users and allocate resources dynamically based on user demand.

4. Rapid elasticity: Cloud computing resources can be scaled up or down quickly and easily in response to changes in user demand, allowing for greater flexibility and cost-effectiveness.

5. Measured service: Cloud computing providers monitor and measure resource usage, enabling users to pay only for the resources they consume.

6. Resilience and reliability: Cloud computing providers typically have redundant systems and geographically dispersed data centres, providing high levels of resilience and reliability.

7. Security and compliance: Cloud computing providers offer a range of security and compliance features, such as access controls, encryption, and audit trails, to protect users' data and meet regulatory requirements.

Cloud Deployment Model

A cloud deployment model refers to how cloud computing resources are made available to users, and how these resources are managed and maintained. There are four main cloud deployment models: public cloud, private cloud, hybrid cloud, and community cloud.

1. Public Cloud

   The public cloud is a cloud computing deployment model where cloud resources, such as servers, storage, and applications, are made available to the general public over the internet by third-party cloud service providers, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform. Public cloud resources are typically shared among multiple customers, and users can access these resources on a pay-as-you-go basis.

   public cloud also has some potential drawbacks, such as security and compliance concerns, limited control over infrastructure, and potential vendor lock-in. Organizations need to carefully consider their requirements and select a public cloud provider that meets their needs in terms of security, compliance, reliability, and performance.

2. Private Cloud

   Private cloud involves the use of cloud computing resources that are dedicated to a single organization and are not shared with other organizations. Private cloud resources can be hosted either on-premises or in a third-party data centre, and are typically managed by the organization's own IT staff.

   A private cloud is a good option for organizations that require greater control over their infrastructure and applications and have specific compliance requirements. However, it may not be the best fit for organizations that require rapid scalability or have limited resources to invest in building and maintaining their private cloud.

3. Hybrid Cloud

   A hybrid cloud is a cloud computing deployment model that combines both public and private cloud resources into a single integrated cloud environment. In a hybrid cloud environment, organizations can leverage the benefits of both public and private clouds to meet their specific needs.

   The hybrid cloud also presents some challenges, such as integration complexity, security risks, and management overhead. Organizations need to ensure that their hybrid cloud environment is properly designed, configured, and secured to avoid potential issues.

4. Community Cloud

   Community cloud involves the use of cloud computing resources that are shared among multiple organizations with similar requirements and interests, such as government agencies or research institutions. The community cloud allows organizations to share resources and costs while maintaining greater control and security compared to the public cloud. Community cloud can be hosted either on-premises or in a third-party data centre.

   a community cloud is a good option for organizations that have similar requirements and interests and want to share the costs of cloud infrastructure and services. It can offer benefits similar to the private cloud, while also providing opportunities for collaboration and knowledge sharing among the members.
