Study Notes
- Cloud capacity planning aims to align resources with demand, minimizing costs while maintaining performance.
Scaling in Cloud Environments
- Vertical scaling involves increasing the resources of a single server or virtual machine.
- Horizontal scaling involves increasing the number of servers or virtual machines.
Cloud Elasticity
- Elasticity is the ability to automatically adjust resources based on demand.
Forecasting Cloud Resource Demand
- Key factors include historical data, growth trends, seasonal variations, and planned events.
Workload Characterization
- Workload characterization identifies resource requirements, usage patterns, and performance bottlenecks.
Monitoring Tools
- Monitoring tools track resource utilization, performance metrics, and application behavior.
Multi-Tenant Cloud Environment Challenges
- Challenges include resource contention, unpredictable workloads from other tenants, and security concerns.
Cloud Service Models
- IaaS (Infrastructure as a Service) requires the most capacity planning.
- PaaS (Platform as a Service) requires less capacity planning.
- SaaS (Software as a Service) requires minimal capacity planning.
Performance Testing
- Performance testing validates capacity plans by simulating workloads and measuring performance metrics.
Noisy Neighbor Problem
- The noisy neighbor problem occurs when one tenant's activity impacts the performance of others.
- It is related to capacity planning by ensuring resource isolation and fair allocation.
Calculating Storage Capacity
- To calculate storage capacity, you must estimate the amount of data, growth rate, and retention policies.
Predictive Scaling
- Predictive scaling uses historical data and machine learning to forecast demand and adjust resources.
- Benefits include proactive resource allocation and reduced latency.
- Drawbacks include potential inaccuracies and the need for continuous monitoring.
Network Bandwidth Impact
- Network bandwidth affects application responsiveness, data transfer rates, and overall system performance.
Resource Utilization
- Resource utilization is the percentage of available resources being used.
- Significance in capacity optimization avoids over-provisioning or under-provisioning.
Cost Models
- Cost models include pay-as-you-go, reserved instances, and spot instances, all of which affects planning depending on budget.
Capacity Audit
- A capacity audit involves reviewing resource usage, performance metrics, and capacity plans.
Peak Demand Periods
- To handle peak demand, you must plan for over-provisioning, auto-scaling, and load balancing.
Automation
- Automation streamlines resource provisioning, scaling, and management.
Serverless Computing
- Serverless computing reduces the need for traditional capacity planning
- It automatically scales resources based on demand.
Disaster Recovery
- Disaster recovery and business continuity require redundant resources, backup systems, and failover mechanisms.
Key Metrics
- Key metrics include CPU utilization, memory usage, network I/O, disk I/O, and response time.
Optimizing Database Capacity
- To optimize database capacity you must use indexing, query optimization, and data partitioning.
Containerized Applications
- Capacity planning for containerized applications involves considering container density, resource limits, and orchestration.
Cloud Security
- Capacity planning ensures adequate resources for security tools, monitoring, and incident response.
Evaluating Effectiveness
- To evaluate effectiveness you must measure performance, cost, and resource utilization against predefined targets.
