Study Notes
Cloud Computing Concepts
- Scalability refers to an application's ability to handle growing amounts of work without degrading performance.
Scaling Configurations
- Vertical scaling involves increasing the capacity of existing hardware or machines.
- Horizontal scaling involves increasing the count of machines without increasing capacity.
- Distributed scaling enables increasing computing power in parallel.
Cloud Computing Benefits
- Pay-as-you-go pricing allows users to pay only for the resources used.
- High Availability refers to a system's ability to remain operational despite hardware or software failures.
Cloud Computing Concepts (continued)
- 'Moving from Capex to Opex' means shifting from capital expenditures to operational expenditures.
- Microsoft Azure is based on a cloud computing concept.
Cloud Computing Reliability
- Fault Tolerance refers to a system's ability to continue operating despite component failures.
Cloud Computing Services
- IaaS (Infrastructure as a Service) is a cloud computing service model.
- PaaS (Platform as a Service) is a cloud computing service model that provides a platform for developing and deploying applications.
- SaaS (Software as a Service) is a cloud computing service model that provides software applications over the internet.
Financial Benefits of Cloud Computing
- 'Pay as you go' means paying for cloud resources only as needed, reducing upfront capital expenditures.
- Shifting from Capital Expenditure (Capex) to Operational Expenditure (Opex) reduces upfront costs and increases flexibility.
