What is one advantage of on-demand resource provisioning in cloud computing?
- It mandates the use of on-premises hardware.
- It allows resources to be provisioned without long-term commitments. (correct)
- It significantly limits the flexibility of resource management.
- It requires pre-provisioning resources beforehand.
How does cloud computing enhance adaptability to changing business needs?
How does cloud computing enhance adaptability to changing business needs?
- By allowing for easy modification or replacement of services on demand. (correct)
- By ensuring that hardware installations are permanent.
- By requiring complex strategies for service migration.
- By making it hard to replace services once deployed.
What role do availability zones play in cloud deployments?
What role do availability zones play in cloud deployments?
- They represent separate locations with independent power and cooling. (correct)
- They serve to reduce the number of racks in data centers.
- They are used to increase physical component failures.
- They eliminate the need for distributing instances.

Study Notes
Cloud Computing Benefits: Agility and Flexibility
-
Limited On-Premises Flexibility: On-premises systems often restrict flexibility due to procurement and deployment processes.
-
On-Demand Resource Provisioning: Cloud resources are provisioned instantly, avoiding pre-provisioning and long-term commitments.
-
Easy Resource Modification and Deletion: Cloud resources are easily modified or deleted, adapting quickly to changing needs, unlike inflexible on-premises hardware.
-
Architectural Flexibility: Cloud platforms allow straightforward transitions between different architectures (e.g., VMs to containers) without significant upfront investment or lengthy migration processes.
-
Effortless Service Migration: Switching between cloud services (e.g., VMs to App Services or managed databases) is easy and efficient.
-
Adaptability to Changing Needs: Easily adjust and replace cloud services in response to evolving requirements and business fluctuations.
Global Scalability
- Leveraging Regions: Cloud platforms utilize multiple regions to accommodate expanding customer bases and adjust geographically.
High Availability and Redundancy in Cloud Deployments
-
Distributed Instances: Cloud services distribute instances across multiple racks, buildings, and data centers for high availability, mitigating the impact of component failures.
-
Availability Zones: Availability zones are distinct physical locations within a region with independent infrastructure (power, networking, cooling). Distribution across availability zones further improves system resilience.
-
Availability Sets and Fault Domains: Availability sets and fault domains logically group resources to prevent correlated failures, ensuring application operation even if a physical component fails (e.g., a rack).
High Availability and Disaster Recovery Strategies
- Availability Zones: Distinct physical locations within a region with independent support infrastructure, increasing resilience via distribution of instances.
Scaling Strategies
-
Auto Scaling: Automatically adjusts the number of instances based on current demand, ensuring optimal resource use and cost efficiency.
-
Horizontal Scaling: Adjusts the number of running application instances to match fluctuating workloads, either adding (scaling out) or removing (scaling in) instances.
-
Dynamic Instance Adjustment: The number of cloud instances dynamically changes (scales up/down) based on workload fluctuations, enabling efficient resource allocation for periods of high or low demand, such as 4 instances during peak usage vs 2 during off-peak times.
