Phase 1: Project Planning and Architecture Design (500 words)

1 Requirements Analysis

The development process begins with a thorough understanding of the application's functional and non-functional requirements. Key considerations include:

• User Base Size: Predicting concurrent users to determine compute resources needed
• Data Volume: Estimating storage requirements for structured/unstructured data
• Latency Requirements: Mapping geographic distribution of users to optimize network routing
• Compliance Needs: Identifying GDPR, HIPAA, or other regulatory requirements

2 Technology Stack Selection

GCP provides flexibility through multiple architectural patterns:

• Serverless Architecture: ideal for stateless applications (e.g., Firebase, Cloud Functions)
• VM-Based Infrastructure: suitable for legacy systems and custom applications
• Containerized Environments: GKE (Google Kubernetes Engine) for microservices
• Serverless + Container Hybrid: Combining Cloud Run with GKE

Example architecture for an e-commerce platform:

Frontend: Firebase + Cloud Run
Backend: GKE clusters with Node.js/Python
Database: Cloud SQL (PostgreSQL) + Firestore
Cache: Memorystore for Redis
Monitoring: Cloud Monitoring + Stackdriver

3 Cost Estimation

GCP's pricing model requires careful planning:

• Compute Costs: VMs ($0.12/hour) vs. preemptible VMs (70% discount)
• Storage Costs: $0.02/GB/month for Cloud Storage
• Network Costs: Data transfer pricing based on zones
• Savings Plans: 20-50% discounts for committed usage

Example cost calculation for a small-scale web app:

• 2x n1-standard-1 VMs ($0.08/hour each)
• 1 TB Cloud Storage ($24/month)
• 100 GB/month data transfer ($0.12)
• Total monthly estimate: ~$80-100

4 Security Strategy

GCP security features implementation:

• Network Security: VPC networks with firewall rules
• Identity and Access Management: IAM roles and service accounts
• Encryption: At-rest (AES-256) and in-transit (TLS 1.3)
• DLP (Data Loss Prevention): Built-in data scanning tools

Phase 2: Infrastructure Provisioning (600 words)

1 Setting Up Virtual Networks

Create and configure VPC networks with:

• Subnets: Public (for internet access) and private (isolated)
• Firewalls: Allow necessary ports (HTTP 80, HTTPS 443)
• Cloud VPN: Connect on-premises infrastructure

Sample VPC configuration:

Project ID: dev-app-project
Region: us-central1
Subnets:
  us-central1-a (public)
  us-central1-b (private)

2 Deploying Compute Resources

Option 1: Managed instance groups

• Auto-scaling based on CPU load
• Rolling updates for OS patches
• Example configuration:

  gcloud compute instance-groups create web-group
  gcloud compute instance-groups managed create web instances \
    --machine-type=n1-standard-2 \
    --num-instances=3 \
    --image-family=ubuntu-2204-lts

Option 2: Preemptible VMs

• Cheaper (70% discount) but can be terminated
• Suitable for batch processing tasks

3 Storage Solutions Implementation

Compare storage options: | Solution | Use Case | Cost (1GB/month) | |-------------------|-----------------------------------|------------------| | Cloud Storage | Object storage, backups | $0.02 | | Cloud SQL | Relational databases | $0.15 | | Cloud Spanner | Global relational DB | $1.50 | | Cloud BigQuery | Analytical datasets | Pay-as-you-go |

Example Cloud Storage setup:

from google.cloud import storage
client = storage.Client()
bucket = client.create_bucket('my-app-bucket')

4 Database Selection and Deployment

Relational Databases

• Cloud SQL: Managed PostgreSQL/MySQL
• Cloud Spanner: Global, horizontally scalable

No-SQL Databases

• Firestore: Real-time NoSQL for mobile apps
• Bigtable: Columnar storage for analytics

Sample Cloud SQL connection string:

postgres://user:password@my-db:5432/mydb

5 Containerization and Orchestration

Setting up GKE cluster

gcloud container clusters create my-cluster \
  --num-nodes=3 \
  --region=us-central1 \
  --machine-type=n1-standard-4 \
  --network=global/networks/my-vpc \
  --subnetwork=my-subnet

Deployment with Helm

helm install my-app ./my-app-values.yaml --namespace=prod

6 CI/CD Pipeline Configuration
