1. Purpose

The purpose of this report is to analyze the current usage of resources, forecast future capacity needs, and ensure that our infrastructure is equipped to handle expected growth in demand over the next 12 months. This capacity planning exercise will help us maintain optimal performance, scalability, and cost efficiency.

2. Current Resource Utilization

2.1. Cloud Infrastructure

  • Compute Resources:
    • Current Usage: 80% of allocated virtual machines (VMs) during peak times.
    • Average CPU Utilization: 65%
    • Memory Utilization: 70% of available capacity
  • Storage:
    • Current Usage: 50 TB of 75 TB allocated (67% utilization)
    • Data Growth Rate: 5 TB per month
  • Network Bandwidth:
    • Peak Utilization: 85% of available bandwidth
    • Average Utilization: 60%

2.2. CI/CD System

  • Build Servers:
    • Current Load: 90% utilization during peak development hours
    • Average Build Queue Time: 5 minutes
  • Deployment Resources:
    • Deployment Time: 30 minutes on average, with occasional delays during high-traffic periods
  • Automated Testing:
    • Current Usage: 75% of testing environments are occupied during peak times

3. Forecasted Growth

Based on historical data and anticipated future needs, we expect the following growth over the next 12 months:

  • Compute Resources: A projected increase of 30% due to new feature development and increased user traffic.
  • Storage Needs: An additional 60 TB to accommodate data growth, primarily driven by user data and logging.
  • Network Bandwidth: A projected increase of 20% to support higher data transfer volumes.
  • CI/CD Workloads: A 40% increase in build and deployment activities due to expanding development teams and faster release cycles.

4. Capacity Requirements

To handle the projected growth and ensure reliable performance, we recommend the following capacity adjustments:

4.1. Compute Resources

  • Current Allocation: 100 VMs
  • Projected Need: Increase to 130 VMs
  • Recommendation: Provision an additional 30 VMs, with auto-scaling configured to handle sudden traffic spikes.

4.2. Storage

  • Current Allocation: 75 TB
  • Projected Need: 135 TB
  • Recommendation: Expand storage capacity by 60 TB and implement data archiving and compression strategies to optimize usage.

4.3. Network Bandwidth

  • Current Capacity: 1 Gbps
  • Projected Need: 1.2 Gbps
  • Recommendation: Increase network bandwidth by 200 Mbps to handle peak loads efficiently and reduce latency.

4.4. CI/CD System

  • Build Servers: Add 4 additional build servers to reduce queue times and support parallel builds.
  • Deployment Infrastructure: Optimize deployment scripts and consider blue-green deployment strategies to improve deployment speed and reliability.
  • Testing Environments: Allocate additional resources to ensure all tests run efficiently without bottlenecks.

5. Cost Analysis

5.1. Compute Resources

  • Current Monthly Cost: $10,000
  • Projected Monthly Cost: $13,000
  • Increase: $3,000 per month

5.2. Storage

  • Current Monthly Cost: $5,000
  • Projected Monthly Cost: $9,000
  • Increase: $4,000 per month

5.3. Network Bandwidth

  • Current Monthly Cost: $2,000
  • Projected Monthly Cost: $2,400
  • Increase: $400 per month

5.4. CI/CD System

  • Build Server Cost: $1,000 per server per month
  • Projected Additional Cost: $4,000 per month

Total Additional Monthly Cost: $11,400

6. Risk Analysis

6.1. Risks of Under-Provisioning

  • Performance Degradation: If resources are not scaled appropriately, users may experience slow response times and service outages.
  • Deployment Delays: Insufficient CI/CD resources may delay releases and impact development productivity.
  • Data Storage Issues: Running out of storage could lead to data loss or require emergency capacity increases at higher costs.

6.2. Mitigation Strategies

  • Auto-Scaling: Configure auto-scaling for compute resources to dynamically adjust to traffic patterns.
  • Monitoring and Alerts: Enhance monitoring tools to provide early warnings of resource exhaustion.
  • Data Management: Implement data retention policies and archiving to optimize storage usage.

7. Recommendations

  1. Increase Compute Resources: Provision 30 additional VMs and configure auto-scaling to handle traffic spikes.
  2. Expand Storage: Allocate an additional 60 TB of storage and implement data management strategies.
  3. Boost Network Bandwidth: Upgrade to 1.2 Gbps to ensure smooth data transfers and reduce latency.
  4. Enhance CI/CD Capacity: Add 4 build servers and optimize deployment processes to meet increasing demand.

8. Next Steps

  1. Approval: Seek budget approval from the Finance Team for the additional monthly cost of $11,400.
  2. Implementation Plan: Develop a phased rollout plan for adding resources, with priority given to critical areas like storage and build servers.
  3. Monitoring Enhancements: Set up enhanced monitoring and alerting for all key resources.

9. Conclusion

This Capacity Planning Report outlines the necessary steps to ensure that TechPro Solutions’ infrastructure remains scalable, efficient, and cost-effective. Proactive planning will enable us to support growth while maintaining optimal performance and reliability.
