National Skill Development Corporation
About the Customer
The National Skill Development Corporation (NSDC) is a Government of India initiative aimed at enabling large-scale skill development across the country. NSDC operates multiple national platforms including the Skill India Portal, SMART portal, LMS platforms, and partner ecosystems that serve trainees, training providers, assessors, and employers across all states and union territories.
With millions of users accessing these platforms, NSDC required a modern, scalable, and cloud-native infrastructure capable of handling high traffic loads, real-time data processing, and nationwide service delivery.
Service Partnership
AppSquadz Technologies Pvt. Ltd. partnered with NSDC to design and implement a cloud-native, highly scalable, and secure architecture on AWS. The engagement included infrastructure assessment, modernization of legacy applications into microservices, implementation of DevSecOps pipelines, and deployment of a high-performance data processing platform. The solution ensured alignment with Government of India compliance requirements including MeitY and CERT-In standards.
