How Hardeep Singh Tiwana Helps Enterprises Navigate Cloud-Native Complexity

As more organizations move their core systems to cloud-native platforms, many are discovering that long-term operation can be more challenging than initial migration. Complex architectures, rising costs, and resilience concerns have led large enterprises to seek specialized guidance on how to manage cloud environments at scale.

At Amazon Web Services (AWS), Senior Technical Account Manager Hardeep Singh Tiwana works with such organizations as they move beyond basic cloud adoption into long-term operational maturity. With more than 23 years of experience in enterprise infrastructure and hybrid cloud modernization, he advises customers whose platforms support significant economic activity across the United States and internationally, including services used by millions of users.

Supporting Cloud Maturity and Resilience

Tiwana’s role at AWS places him at the intersection of architecture, operations, and long-term strategy. His focus areas include Kubernetes orchestration on Amazon Elastic Kubernetes Service (EKS), resilience engineering, and multi-region fault tolerance. These are domains where design decisions made early on can have lasting financial and operational implications.

A significant part of his work involves helping enterprises standardize on container platforms using Amazon EKS. He collaborates with customers to implement high-reliability approaches such as blue–green and canary releases. These practices are used by organizations running high-volume applications in geographically distributed markets, where maintaining availability is critical.

Economic Impact and Technical Contributions

Beyond architectural resilience, Tiwana has been involved in cost-optimization initiatives that identify inefficiencies and improve utilization. Several enterprises he works with have reported double-digit percentage reductions in cloud expenditure while maintaining application performance.

This work builds on his tenure at Gap Inc., where he served as Director of Hybrid Cloud Engineering. During that period, he led data center consolidation and hybrid cloud initiatives that generated tens of millions of dollars in cost savings and fundamental improvements in operational resilience.

Tiwana also contributes to the cloud-native knowledge base through authored technical guidance. In 2024, he co-authored a guide for the AWS Containers Blog titled “Migrating from AWS App Mesh to Amazon VPC Lattice,” which provides a roadmap for modernizing microservice networking. The guide has been adopted as a reference by engineering teams seeking to simplify service connectivity while adopting managed networking services.

Recognition in the Kubernetes Community

In December 2024, Tiwana earned the Kubestronaut designation from the Cloud Native Computing Foundation (CNCF) after completing a sequence of performance-based Kubernetes-related certifications. The program is known for examinations that simulate real production scenarios in administration, development, and security. At the time of his achievement, the global Kubestronaut community remained small compared with the wider Kubernetes practitioner population, reflecting the rigor required to complete the full certification sequence.

Tiwana’s recognition in the Kubernetes community and his advisory work at AWS reflect a broader shift in how enterprises approach cloud-native operations. As organizations continue to rely on these platforms for commerce, digital services, and software delivery, specialists who combine long-term infrastructure experience with practical Kubernetes skills are playing a growing role in shaping how large-scale cloud environments are designed and run.
