The following are the types of Cloud Computing:
1. Infrastructure as a Service ( IaaS )
- Flexibility and Control: IaaS comes up with providing virtualized computing resources such as VMs, Storage, and networks facilitating users with control over the Operating system and applications.
- Reducing Expenses of Hardware: IaaS provides business cost savings with the elimination of physical infrastructure investments making it cost-effective.
- Scalability of Resources: The cloud provides in scaling of hardware resources up or down as per demand facilitating optimal performance with cost efficiency.
2. Platform as a Service ( PaaS )
- Simplifying the Development: Platform as a Service offers application development by keeping the underlying Infrastructure as an Abstraction. It helps the developers to completely focus on application logic ( Code ) and background operations are completely managed by the AWS platform.
- Enhancing Efficiency and Productivity: PaaS lowers the Management of Infrastructure complexity, speeding up the Execution time and bringing the updates quickly to market by streamlining the development process.
- Automation of Scaling: Management of resource scaling, guaranteeing the program’s workload efficiency is ensured by PaaS.
3. SaaS (software as a service)
- Collaboration And Accessibility: Software as a Service (SaaS) helps users to easily access applications without having the requirement of local installations. It is fully managed by the AWS Software working as a service over the internet encouraging effortless cooperation and ease of access.
- Automation of Updates: SaaS providers manage the handling of software maintenance with automatic latest updates ensuring users gain experience with the latest features and security patches.
- Cost Efficiency: SaaS acts as a cost-effective solution by reducing the overhead of IT support by eliminating the need for individual software licenses.
4. Function as a Service (FaaS)
- Event-Driven Execution: FaaS helps in the maintenance of servers and infrastructure making users worry about it. FaaS facilitates the developers to run code as a response to the events.
- Cost Efficiency: FaaS facilitates cost efficiency by coming up with the principle “Pay as per you Run” for the computing resources used.
- Scalability and Agility: Serverless Architectures scale effortlessly in handing the workloads promoting agility in development and deployment.
Characteristics of Cloud Computing
On-demand self-services: The Cloud computing services does not require any human administrators, user themselves are able to provision, monitor and manage computing resources as needed.
Broad network access: The Computing services are generally provided over standard networks and heterogeneous devices.
Rapid elasticity: The Computing services should have IT resources that are able to scale out and in quickly and on a need basis. Whenever the user require services it is provided to him and it is scale out as soon as its requirement gets over.
Resource pooling: The IT resource (e.g., networks, servers, storage, applications, and services) present are shared across multiple applications and occupant in an uncommitted manner. Multiple clients are provided service from a same physical resource.
Measured service: The resource utilisation is tracked for each application and occupant, it will provide both the user and the resource provider with an account of what has been used. This is done for various reasons like monitoring billing and effective use of resource.
Multi-tenancy: Cloud computing providers can support multiple tenants (users or organizations) on a single set of shared resources.
Virtualization: Cloud computing providers use virtualization technology to abstract underlying hardware resources and present them as logical resources to users.
Resilient computing: Cloud computing services are typically designed with redundancy and fault tolerance in mind, which ensures high availability and reliability.
Flexible pricing models: Cloud providers offer a variety of pricing models, including pay-per-use, subscription-based, and spot pricing, allowing users to choose the option that best suits their needs.
Security: Cloud providers invest heavily in security measures to protect their users’ data and ensure the privacy of sensitive information.
Automation: Cloud computing services are often highly automated, allowing users to deploy and manage resources with minimal manual intervention.
Sustainability: Cloud providers are increasingly focused on sustainable practices, such as energy-efficient data centers and the use of renewable energy sources, to reduce their environmental impact
