AWS Cloud Architecture for Enterprise ERP

1. AWS Cloud Architecture for
Enterprise ERP
Scalable, Secure, and Cost-Effective
Odoo Deployment
AWS Best Practices and Technical
Deep Dive

2. Executive Summary
• • Enterprise-grade ERP deployment on AWS
cloud
• • High availability with 99.99% uptime SLA
• • Auto-scaling architecture for dynamic
workloads
• • Multi-layer security with AWS native services
• • Cost optimization through right-sizing and
automation
• • Disaster recovery with RTO < 4 hours, RPO <
1 hour

3. Current State vs Future State
• Current State (On-Premises):
• • Fixed capacity with over-provisioning
• • Manual scaling and maintenance
• • Single point of failure risks
• • High CAPEX investment
• • Limited disaster recovery options
• Future State (AWS Cloud):
• • Elastic capacity with auto-scaling

4. AWS Well-Architected Framework
• Operational Excellence:
• • Infrastructure as Code
(CloudFormation/Terraform)
• • Automated monitoring and alerting
• Security:
• • Defense in depth with multiple security
layers
• • Encryption at rest and in transit

5. Detailed AWS Architecture
• Internet Gateway & Route 53:
• • DNS management and traffic routing
• • Health checks and failover
• Application Load Balancer:
• • Layer 7 load balancing
• • SSL termination and WAF integration
• Auto Scaling Groups:

6. Compute Services Deep Dive
• EC2 Instance Types:
• • Production: m5.large or m5.xlarge
• • Development: t3.medium
• • Reporting: r5.large (memory optimized)
• Auto Scaling Configuration:
• • Min: 2 instances, Max: 10 instances
• • Scale out: CPU > 70% for 5 minutes
• • Scale in: CPU < 30% for 10 minutes

7. Database Architecture
• Amazon RDS PostgreSQL:
• • Multi-AZ deployment for high availability
• • Automated failover in < 60 seconds
• • Instance class: db.r5.xlarge (production)
• Backup Strategy:
• • Automated daily backups
• • 35-day backup retention
• • Point-in-time recovery capability

8. Storage and Content Delivery
• Amazon S3:
• • Document and file attachment storage
• • 99.999999999% (11 9s) durability
• • Lifecycle policies for cost optimization
• • Cross-region replication for DR
• Amazon EFS:
• • Shared file system for multi-instance setup
• • Automatic scaling and high availability

9. Security Architecture
• Network Security:
• • VPC with public/private subnets
• • Security Groups (stateful firewall)
• • NACLs (stateless firewall)
• • VPC Flow Logs for monitoring
• Identity and Access Management:
• • IAM roles and policies
• • Multi-factor authentication

10. Monitoring and Observability
• Amazon CloudWatch:
• • Custom dashboards and metrics
• • Automated alerting via SNS
• • Log aggregation and analysis
• • 15-month metric retention
• AWS X-Ray:
• • Distributed tracing for performance
• • Service map visualization

11. Disaster Recovery Strategy
• Multi-AZ Deployment:
• • Primary: us-east-1a
• • Secondary: us-east-1b
• • Automatic failover for RDS
• Cross-Region Backup:
• • Daily snapshots to us-west-2
• • S3 cross-region replication
• • AMI copies for quick recovery

12. Cost Optimization Strategies
• Reserved Instances:
• • 1-year or 3-year commitments
• • Up to 75% savings vs On-Demand
• • Convertible RIs for flexibility
• Spot Instances:
• • Development and testing environments
• • Up to 90% savings vs On-Demand
• • Fault-tolerant workloads

13. Migration Approach
• Assessment Phase:
• • AWS Application Discovery Service
• • Dependency mapping and analysis
• • Performance baseline establishment
• Migration Strategies (6 Rs):
• • Rehost: Lift and shift to EC2
• • Replatform: Optimize for cloud
• • Refactor: Cloud-native redesign

14. Technical Implementation
Roadmap
• Phase 1: Foundation (Weeks 1-2)
• • VPC setup and network configuration
• • IAM roles and security policies
• • Monitoring and logging setup
• Phase 2: Core Services (Weeks 3-4)
• • EC2 instances and Auto Scaling
• • RDS database deployment
• • Load balancer configuration

15. Success Metrics and KPIs
• Performance Metrics:
• • Application response time < 2 seconds
• • Database query performance < 500ms
• • 99.99% uptime SLA achievement
• Cost Metrics:
• • 20-30% reduction in total IT costs
• • Predictable monthly operational expenses
• • ROI achievement within 12 months
