About the Client:

Banque Misr (BM) was established in 1920 by the pioneer economist and financial expert Mohamed Talaat Harb Pasha, who spearheaded the concept of investing in national savings and directing them toward economic and social development. Thus, Banque Misr was established as the first wholly Egyptian-owned bank.

Banque Misr has funded many businesses spanning across multiple domestic sectors, such as: textiles, insurance, transportation, aviation, entertainment, and filmmaking. Currently, BM owns shares in 157 companies across different fields, ranging from finance, tourism, housing, agriculture and food, and communication and information technology.

 

Problem Statement/Definition

Organizations often struggle with scalability, security, and operational efficiency when migrating workloads to the cloud. Traditional infrastructure limits agility increases costs, and creates challenges in high availability, disaster recovery, and compliance.

The need for a well-architected AWS solution is essential to overcome these limitations while ensuring a smooth migration and modernization process.

Proposed Solution & Architecture

The provided AWS architecture diagram presents a robust cloud-native solution incorporating security, scalability, automation, and monitoring best practices. The key components include:

• Networking & Security: Implementation of AWS Transit Gateway, Load Balancers, Palo Alto Firewalls, and AWS Security Groups for network segmentation and traffic control.
• Compute & Storage: Utilization of EC2 instances, Auto Scaling Groups, and S3 storage for flexible compute and storage management.
• Monitoring & Logging: Integration with AWS CloudWatch, AWS Config, and AWS Security Hub for observability and compliance.
• Automation & Infrastructure as Code: Terraform is leveraged to automate deployments and maintain infrastructure consistency.
• Data & Analytics: AWS services like Redshift, Kinesis, and Glue are incorporated for data processing and analytics.

 

Outcomes of Project & Success Metrics

• Improved Scalability: Auto Scaling ensures resource optimization based on demand.
• Enhanced Security: Implementation of AWS-native security services and third-party firewalls.
• Cost Optimization: Right-sizing of instances and serverless components for cost efficiency.
• Operational Efficiency: Automated deployments using Terraform reduce manual overhead.
• Compliance & Governance: AWS Security Hub and Config ensure adherence to best practices.
