About Customer

Industry: Government

The Assam Power Distribution Company Limited (APDCL) is a state-owned power distribution company in India, established in 2009. With a mission to provide reliable, affordable, and quality electricity to all customers, APDCL offers a wide range of services, including electricity supply, metering, billing, customer service, load management, and energy efficiency services. Its robust infrastructure encompasses over 300,000 kilometers of transmission and distribution lines, 20,000 transformers, and 10 million meters. Financially sound with a turnover of over Rs. 8,000 crore in 2022-23, APDCL has been recognized for its excellence in energy management and conservation. Despite facing challenges such as high electricity demand, aging infrastructure, financial constraints, and rural electrification, APDCL remains committed to its future plans, including investing in new technologies, expanding its network, and reducing its carbon footprint.

Current Infrastructure

APDCL’s current IT infrastructure is a hybrid cloud environment, combining on-premises and cloud-based resources. The cloud-based infrastructure consists of Amazon Virtual Private Cloud (VPC), Amazon Elastic Compute Cloud (EC2), Amazon Simple Storage Service (S3), Amazon Relational Database Service (RDS), and Amazon CloudTrail. The on-premises infrastructure includes a data center, network infrastructure, and security infrastructure. This hybrid cloud architecture provides APDCL with scalability, flexibility, cost- effectiveness, security, and compliance

The Challenge

EC2 instance sizing needs to be re-evaluated to optimize for cost and performance. A multi-AZ setup is recommended to improve availability and disaster recovery capabilities. Changes to the architecture should be carefully considered to avoid impacting costs. A breakdown of the project into smaller milestones is recommended to manage stringent timelines. AWS CloudWatch can be used to identify performance bottlenecks. A dedicated project sponsor should be identified from the business to advocate for the project. Regular communication channels should be established with the existing partner to ensure they are kept informed. The customer should be able to provide the required testing assets and tools.

The Solution

To optimize EC2 instance sizing for cost and performance, consider using smaller instances, reserved instances, or Spot instances. Utilize AWS Cost Explorer to monitor spending and AWS Auto Scaling to dynamically adjust instance capacity. Transition from a Single AZ setup to multi-AZ for improved availability, employing Amazon CloudWatch and Route 53 Health Checks for monitoring and automatic failover. When implementing architecture changes, carefully assess their impact on costs and leverage the AWS Well-Architected Framework for secure, reliable, and cost-effective designs. To meet stringent timelines, break down the project into manageable milestones, employ agile methodologies, and automate code deployment with AWS Code Build and Code Deploy. Identify and address performance bottlenecks using AWS CloudWatch, offload tasks with AWS Lambda, and leverage caching with Amazon Elastic cache and data storage with Amazon DynamoDB. Ensure business support by identifying a dedicated project sponsor, maintaining communication with partners, and utilizing AWS Partner Network (APN) for additional support. For testing, collaborate with the customer to provide necessary assets, and automate testing with AWS Code Pipeline, securely storing code changes in AWS Code Commit, and managing releases with AWS Code Star.
