Study Notes

Benefits of Cloud Computing

Companies can select a tailored approach to using cloud services, optimizing costs by utilizing cloud resources to their specific needs.

Lift and Shift

Gradual migration strategy allowing businesses to save on infrastructure and administrative costs by moving existing systems to the cloud.

Key Advantages of Cloud Computing

Cost-effective through consumption-based pricing.
Scalable to accommodate varying levels of demand.
Elasticity enables dynamic resource allocation based on workload fluctuations.
Always current, with automatic maintenance handled by cloud providers.
Reliable, ensuring data availability and protection.
Secure, integrating both physical and digital security measures.

Cost-Effectiveness

Employs a pay-as-you-go model, minimizing unnecessary expenses by only charging for utilized resources.

Benefits of Pay-as-You-Go Model

Eliminates upfront infrastructure costs.
Avoids paying for unused infrastructure.
Allows additional resource purchase as required.
Provides flexibility to cease payments for unnecessary resources.
Enhances cost predictability.
Facilitates performance evaluation through historical data analysis.

Scalability in Cloud Computing

Resources can be increased or decreased based on demand levels, with options for manual or automated adjustment.

Types of Scaling

Vertical Scaling: Enhancing power of existing servers by adding resources.
Horizontal Scaling: Expanding capacity by adding more servers functioning collectively.

Elasticity of Cloud Computing

Automatically adjusts resources in response to changing workloads, accommodating spikes in traffic effectively.

Current Nature of Cloud Computing

Maintenance is managed by cloud providers, enabling companies to focus on developing and deploying applications without maintenance burdens.

Reliability of Cloud Computing

Offers options that guarantee data accessibility whenever required.

Fault Tolerance

Refers to redundancy; backup systems automatically take over in case of component failure, ensuring uninterrupted service during disasters.

Global Presence of Cloud Computing

Features redundant data centers worldwide, allowing for regional service replication and compliance with data-residency regulations.

Security in Cloud Computing

Combines physical and digital security measures for robust data protection.

Physical Security in Cloud Computing

Significant investments in physical safety measures, such as surveillance systems and security personnel, to protect data centers.

Digital Security in Cloud Computing

Implements strict access controls for cloud resources and provides tools to mitigate security threats effectively.
