Current System Status: Inadequate for Expansion and Modern Technology

PTSC's current ERP system runs on a cluster of physical servers in on-premises infrastructure. The system, developed, built, maintained, and deployed by PTSC, comprises several key components, such as IIS web application virtual machines and virtual machine clusters for warehouse and project construction management. A dedicated data storage server is also responsible for storing detailed information on architectural designs and project documentation. Notably, the system includes two virtual machines dedicated to databases, playing a central role in data management and processing.

This ERP system serves as a platform for essential internal services and is a crucial tool for the corporation's daily operations, with about 1500 regular users daily. The stability and reliability of the system are critical, but PTSC also recognizes the need to expand and update the system to meet the growing needs of users and future business development.

Challenges Faced - Deteriorating IT Infrastructure

After years of operation and development, PTSC faces significant challenges in optimizing its IT infrastructure. This stems from the increasing complexity of the system and its long "age," making it challenging to implement the necessary adjustments to meet current and future business requirements.Another challenge is the impending expiration of Windows Server and MS SQL systems licenses, presenting PTSC with a considerable expense if they decide to renew. Given this situation, PTSC must seek alternative solutions that are cost-effective and align with the company’s long-term strategy and objectives, ensuring the continuity and efficiency of the IT infrastructure.

System Migration to the Cloud with AWS

After reviewing and assessing the system's current state, CMC Telecom implemented a Re-host and Re-platform strategy to migrate PTSC's approach to the cloud. This decision was made after thoroughly examining PTSC's system complexity, the need to minimize operational disruptions, and the desire to leverage AWS Native Services technology to improve performance and reliability.

CMC Telecom’s solution architects comprehensively assessed the current system and developed an appropriate solution, ensuring that all challenges were effectively addressed. Once agreed upon by PTSC, this plan led to the construction of new infrastructure on AWS and the seamless migration process for all applications. Throughout the transition process, CMC Telecom carried out thorough testing, assessment, and continuous adjustments to ensure the system's stable operation without any issues. Consequently, on schedule, the migration process was successful with minimal operational disruptions, achieving the goal for PTSC. This demonstrates the effectiveness and success of the cloud migration strategy.

Workload PTSC ERP on AWS

To achieve high performance and ensure optimal availability, PTSC's ERP system has fully leveraged AWS Native Services. This process has minimized the need to modify the system structure or application source code. CMC Telecom's solution architects effectively integrated multiple AWS services and implemented infrastructure deployment as code using Terraform and AWS Cloud Formation. As a result, PTSC significantly improved deployment time, reduced errors, and enhanced the ability to monitor the process from start to finish comprehensively.

CMC Telecom also utilized a range of AWS services to enhance the availability and security of PTSC's ERP system. These services include Application Load Balancer, AWS Auto Scaling, and Amazon Relational Database Service (RDS) with Multi-AZ, RDS Proxy, and AWS Virtual Private Network (VPN) Site to Site and AWS Direct Connect. This combination ensures a secure and continuous connection between the On-Premises environment and AWS, thereby enhancing the flexibility and reliability of the ERP system.

Using AWS DataSync, CMC Telecom migrated PTSC's existing data to S3 Storage and Amazon FSx through a secure VPN Site-to-site connection. The AWS DataSync Agent was configured at PTSC's infrastructure to optimize this process, facilitating smooth and efficient data transmission management.

PTSC's file data is stored on Amazon FSx for Windows File Server with Multi-AZ enabled to ensure high availability and stable performance. Amazon FSx stands out with its ability to automatically monitor and address hardware failures, replacing infrastructure components as needed. This not only enhances data availability but also ensures continuity during system maintenance.

PTSC's ERP System Enhanced with Increased Security

CMC Telecom has bolstered the security of PTSC's ERP system by implementing a Web Application Firewall and AWS Shield, which help manage traffic and prevent DDoS attacks.
