How Microsoft Technologies Enabled the Outcome · Reliance Infosystems Reliance Infosystems <
Zero Trust Capabilities Enabling Secure Tenant Separation
AKS was implemented as the core container orchestration platform for enterprise workloads, enabling microservices deployment, scaling, and lifecycle management across multiple applications.
Legacy applications were replatformed and refactored into distributed microservices, improving scalability, maintainability, and deployment flexibility.
Dev, SIT, UAT, and Production environments were implemented with standardized governance and deployment pipelines.
Azure Front Door and Application Gateway with WAF enabled secure global routing, traffic distribution, and protection for high-traffic applications.
Azure Database for PostgreSQL, MySQL Flexible Server, Cosmos DB (MongoDB API), and Azure Cache for Redis improved transactional performance and reduced latency.
Azure Service Bus, API-led architecture, and containerized integration services enabled reliable communication between systems and third-party platforms.
Microsoft Defender for Cloud, Microsoft Sentinel, Microsoft Entra ID, Azure Key Vault, and Azure Policy ensured a secure-by-design and compliant cloud environment.
Azure DevOps and GitHub enabled CI/CD automation, GitOps practices, and standardized release management across all environments.
Hub-and-spoke architecture enabled secure segmentation of workloads with centralized governance and controlled hybrid connectivity.
