Study Notes
Economic Reasons for Cloud Attractiveness
- Scalability and flexibility reduce capital expenditures (CAPEX) and operational expenditures (OPEX)
- Pay-as-you-go pricing model lowers costs and enables cost-effective scaling
- Reduced maintenance and upgrade costs due to cloud provider management
Benefits for Application Developers
- Rapid deployment and prototyping enable faster time-to-market
- Access to a vast array of tools, services, and technologies
- Greater flexibility in choosing programming languages, frameworks, and architectures
- Auto-scaling and load balancing enable efficient resource utilization
Reducing Execution Time
- Distributing compute-intensive tasks across multiple virtual machines (VMs) reduces execution time
- Data-intensive applications benefit from data parallelism and distributed data processing
- High-performance computing (HPC) enables faster execution of complex tasks
Advantages of Architectural Styles
- Modularity and loose coupling enable flexibility and scalability
- Separation of concerns promotes maintainability and reusability
- Easier integration with third-party services and APIs
Cloud Computing Application Example
- Online collaborative document editing tools, such as Google Docs
