2. Types of models available in cloud computing
2.1 Client-server model.
A style of computer network architecture known as client-server computing involves clients connecting to servers to utilize resources and services. services offered by the cloud computing infrastructure. In this approach, servers are in charge of organizing and delivering the ongoing service, while clients consume and get access to those resources and services via an internet connection. Users benefit from the flexibility, security, and usability offered by the client-server architecture in cloud computing, which also aids in resource management and optimization for enterprises.
Fi gure: Client-server model ( Client–server model 2023)
2.2 Peer to Peer model
A sort of computer network architecture known as peer-to-peer computing uses computers that are directly connected to one another through the internet to share resources. rather than being forced to use a central server. The computers used in the peer-to-peer paradigm are thought of as being equal and are capable of serving as clients or servers. The computers in the network answer user requests while resources are divided equally among them under the peer-to-peer paradigm. Cloud computing's peer-to-peer paradigm is appropriate for small, straightforward systems or for centralized resources on personal computers. Fig ure: Peer to peer model ( Mạng Ngang Hàng 2023)
Figure: On-demand self-service (Ayyu et al., Cloud computing "The characteristics"? part 2 2018)
3.2 Broad network access
Wide Area Network (WAN) is the method used in cloud computing to link and send data across cloud services spread out across the world. Users and systems operating remotely may rapidly and effectively access data and resources in the cloud thanks to a WAN. Virtual network connections, such as Virtual Private Networks (VPNs) or Virtual Private Clouds (VPCs), can be used to access a large network. Users can connect to the cloud network over a VPN network utilizing encryption techniques to maintain security. A VPC, on the other hand, enables resources to connect to one other safely and effectively by serving as a private network in the cloud for systems hosted on the same cloud platform. Globally utilized and crucial for enabling dispersed cloud systems is broad network connectivity. Figure: Broad Network Access ( 11 4 examining Broad Network Access CCNA Data Center DCICT 2017)
3.3 Resource pooling
One of the fundamental components of cloud computing is resource pooling. With the use of this functionality, cloud service providers may pool their computing, network, and storage resources and make them accessible to a variety of clients. These resources may be used by clients concurrently and independently of one another thanks to the creation of a large computing environment by the collection of these resources. Resource aggregation helps cloud service providers to adapt swiftly to the resource utilization requirements of their clients. Resource aggregation also aids in resource utilization optimization, reducing resource waste. Figure: Resource Pooling (AudvikLabs, What is resource pooling in cloud computing? - audvik labs 2023)
3.4 Rapid elasticity
One of the crucial aspects of cloud computing is elasticity. It enables cloud systems to change their resource allocation in response to changing consumer demands. This implies that resources may be swiftly and flexibly adjusted to suit changing user demands. Cloud systems that are resilient can quickly respond to client resource use requests. This increases the effectiveness of cloud systems and optimizes resource utilization while cutting down on waste. Agile in cloud computing includes the following features in particular: Depending on the demands of the consumer, resources might be increased or decreased. Resource sizing or reducing occurs automatically or at the user's request. Resources can be expanded or contracted automatically or at the user's request. Scaling or decreasing of resources may be done without any system or network disruption.

II. Design an appropriate architectural Cloud Computing framework for a given
scenario (P2)
1. Architectural Cloud Computing frameworks
These architectures provide common architectural models that can be applied to cloud-based environments to solve common problems and fulfill common requirements. The architectures covered in this chapter include:
- Workload Distribution Architecture : This architecture distributes workloads across redundant IT resources to increase scalability and reliability.
- Resource Pooling Architecture: This architecture enables the sharing of IT resources among multiple cloud consumers to increase resource utilization and reduce costs.
- Dynamic Scalability Architecture: This architecture enables the dynamic allocation and deallocation of IT resources in response to changing demand to increase scalability and reduce costs.
- Elastic Resource Capacity Architecture: This architecture enables the dynamic allocation and deallocation of virtual IT resources in response to changing demand to increase scalability and reduce costs.
I choose this model The dynamic scalability architecture can be applied to a range of IT resources, including virtual servers and cloud storage devices. Besides the core automated scaling listener and resource replication mechanisms, the following mechanisms can also be used in this form of cloud architecture:
- Cloud Usage Monitor – Specialized cloud usage monitors can track runtime usage in response to dynamic fluctuations caused by this architecture.
- Hypervisor – The hypervisor is invoked by a dynamic scalability system to create or remove virtual server instances, or to be scaled itself.
- Pay-Per-Use Monitor – The pay-per-use monitor is engaged to collect usage cost information in response to the scaling of IT resources. These frameworks provide guidance on how to design and operate reliable, secure, efficient, and cost-effective systems in the cloud. They cover a wide range of topics such as security, reliability, performance efficiency, cost optimization, and operational excellence.
III. Define an appropriate deployment model for a given scenario (P3)
1. Deployment Models
To meet client demands and objectives, cloud computing provides a wide variety of deployment types. Public, private, and hybrid clouds are the three primary deployment methods, though. Public Cloud: A form of the cloud where resources are shared and controlled for all users by cloud service providers. Customers just need an internet connection to use the resources that are available on the internet platform. Private Cloud: A private cloud model that is fully owned and operated by a company or organization. The private cloud is housed in a data center and is solely used internally by the company.
Cloud hybridization refers to a paradigm that combines public and private clouds. Organizations utilize the private cloud for sensitive or highly secure applications while using the public cloud for less sensitive or less secure applications. To maximize resource efficiency, public and private clouds are combined.
2. Public Cloud
Major cloud providers like Amazon, Microsoft, Google, and many more provide the Public Cloud, one of the primary cloud models in Cloud Computing. Customers can access cloud resources (such servers, storage, and networks) in the public cloud using the internet or other network protocols. These resources are pooled and controlled by the provider. When used by organizations and corporations, the public cloud offers a number of advantages, including: High degree of adaptability: Customers can modify the size of cloud resources to suit their requirements. High Availability: The Public Cloud offers a high level of availability and dependability since cloud resources are expertly managed and deployed on substantial infrastructure. Low cost: Purchasing and maintaining the necessary hardware for data processing and storage is expensive. Customers can access and use cloud resources at a lesser cost by using the public cloud. Resource management is made easier since system administration labor for the client is reduced because cloud providers are in charge of managing and maintaining cloud resources.
