The Metaphor Way: Cloud Core Principles on Performance:
In cloud architecture, Scalability and Elasticity are two sides of a coin; Efficiency is the toss; resulting whether Reliability or Availability always ensures seamless user experience
The Metaphor Way:
Scalability and elasticity as two sides of a coin, and efficiency as the toss itself, with reliability and availability being the outcome (head or tail).
Concept | Definition | Key Focus | GCP Example |
Scalability | Ability to increase/decrease resource capacity based on workload demands (manual or automated). | Growth & Adaptability | Scaling GKE cluster nodes or compute engine instances manually or via autoscaling policies. |
Elasticity | Automatic, dynamic scaling in/out based on real-time workload changes without manual intervention. | Auto-adjustment, Flexibility | Using GCP Autoscaler to automatically add/remove VM instances based on CPU usage. |
Efficiency | Optimal resource utilization, ensuring no wastage while meeting workload needs. | Cost & Resource Optimization | Right-sizing VMs, leveraging Preemptible VMs, or sustained-use discounts in GCP. |
Reliability | The system consistently performs without failure under expected conditions over time. | Consistency and Stability | Deploying GCP services across multiple zones/regions to avoid single points of failure. |
Availability | Ensuring systems/resources are accessible when needed is often measured via uptime percentages (SLA/SLO). | Uptime & Accessibility | Multi-regional GCS buckets, Cloud Load Balancer distributing traffic to healthy backend VMs. |
