The IT support team focused on creating a robust, scalable, and high-performing IT environment.

1. Pre-Upgrade Assessment and Planning

• Infrastructure Audit: Analyzed servers, databases, and network setups.

• Performance Metrics: Identified transaction bottlenecks and system weaknesses.

• Scalability Analysis: Assessed future demands based on growth projections.

• Risk Management: Developed strategies to mitigate downtime risks during migration.

• Cloud Transition Plan: Designed a hybrid cloud strategy for elasticity and cost-efficiency.

2. Infrastructure Optimization and Cloud Migration

• Hybrid Cloud Model: Migrated critical workloads to AWS and Azure while maintaining some on-premise systems for regulatory compliance.

• Auto-Scaling: Enabled real-time resource scaling to match traffic demands, reducing costs and ensuring availability.

• Load Balancers: Distributed traffic globally to minimize latency and prevent overload.

• Microservices Adoption: Transformed the monolithic architecture into independent microservices to improve flexibility and fault tolerance.

3. Performance and Availability Monitoring:

• Real-Time Monitoring: Deployed tools like Datadog and New Relic to track performance metrics and transaction health.

• Proactive Alerting: Set thresholds to notify teams of anomalies before they impacted users.

• Database Optimization: Streamlined queries and implemented database indexing to handle peak loads efficiently.

• Edge Caching: Used Redis for frequently accessed data, reducing retrieval time and server strain.

4. Post-Migration Optimization:

• System Hardening: Implemented robust encryption and access controls, including multi-factor authentication.

• Stress Testing: Simulated extreme traffic conditions to ensure stability under heavy loads.

• Capacity Planning: Prepared for future growth by forecasting transaction volumes and infrastructure needs.

5. Continuous Improvement and Automation:

• CI/CD Pipelines: Automated software updates and deployment with no downtime.

• Cost Optimization: Right-sized cloud instances and used reserved capacity for predictable workloads.

• Resource Monitoring: Periodically analyzed and reallocated resources to optimize performance and costs.
