About the Client

Our client is a prominent public corporation in India’s energy and power sector, managing customer accounts, payments, complaints, and other customer-focused services. They sought to balance cost and performance by migrating from a monolithic data center to the cloud, enhancing application and data security through role-based access, and introducing automation best practices.

Challenge

The client sought to enhance customer experience by adopting new-age technologies and improving their infrastructure. Legacy systems posed challenges in technology integration and scalability, prompting the need for a more advanced solution. The client wanted to ensure a cost-effective and high-performance migration from their monolithic data center to the AWS cloud. They require role-based access controls to enhance applications and data security and implement automation best practices to streamline operations and increase efficiency. The client wanted to smoothly transition to cloud technologies through data center migration, security integrations, and automation while effectively balancing cost and performance.

Solutions Implemented

The client’s cloud journey started with setting up an AWS Landing Zone, a time-saving solution that establishes a secure and scalable environment for running workloads. This setup ensures seamless connectivity with existing on-premises environments through redundant VPN connections to the remaining network infrastructure. The Landing Zone is the cornerstone for cloud migration, addressing critical needs such as security, implementation speed, integration with existing infrastructure, cost control, and capacity to support digital transformation and migration requirements.

Amazon CloudWatch for Proactive Monitoring

Deployed Amazon CloudWatch to collect and monitor real-time logs and performance metrics from EC2 instances and database environments. This enabled proactive alerting, faster root cause analysis, and improved system uptime across production workloads.

Amazon IAM and VPC for Security and Access Control

Implemented Identity and Access Management (IAM) and a Virtual Private Cloud (VPC) to ensure secure resource access. Role-based permissions and encrypted VPCs helped maintain a secure posture while meeting internal compliance and data protection policies.

Elastic Load Balancing for High Availability

Integrated Elastic Load Balancing (ELB) to distribute traffic across multiple EC2 instances, improving application responsiveness and ensuring high availability during traffic spikes or maintenance periods.

Amazon Aurora

This was deployed for MySQL and automates administrative tasks like hardware provisioning, database setup, patching, and backups.

Backup and Disaster Recovery

Automated backups of DB instances securely stored in Amazon S3 to ensure reliable backup and disaster recovery.

Amazon EC2 Linux Instances

Migrated open-source CentOS servers and COTS RedHat-based server applications, enabling quick scale capacity adjustments as computing requirements change.

Outcome

Providing results that exceeded the client’s expectations

Enhanced Security

Role-based access controls and automated backups ensure robust data security and compliance.

Reliable Disaster Recovery

Automated backups in Amazon S3 ensure minimal downtime and quick recovery.

Seamless Connectivity

Transit Gateway enables smooth integration with existing on-premises systems, supporting a hybrid cloud infrastructure.

Efficiency and Effectiveness

This comprehensive migration work was completed in just 14 weeks, demonstrating the efficiency and effectiveness of the implemented solution.

"When we engaged with Successive Digital, our infrastructure was functional—but far from efficient. We needed more reliability, flexibility, and control as our IoT platform expanded. Successive team quickly assessed our needs and migrated us to a cloud-native architecture using Amazon Aurora, EC2, and other AWS-native services. Successive Digital didn’t just help us migrate—they helped us modernize with precision and purpose. It’s been a true value-driven partnership."
