On November 1, 2025, ConcertIDC’s CTO, Kannan K, took the stage at TechXConf 2025, Asia’s largest AI and Cloud conference, held at the Chennai Trade Centre. His technical session, “Fake It Till You Make It: Emulating Cloud with LocalStack for Microservices,” drew developers, architects, and DevOps professionals eager to learn how to accelerate cloud-native development while cutting costs and complexity.
Building and testing microservices on AWS is robust—but it’s also expensive and slow. Provisioning resources, waiting on deployments, and debugging across distributed environments all add friction.
In his demo-driven talk, Kannan showed how LocalStack, a local AWS emulator, can remove these bottlenecks entirely. By running key AWS services—like API Gateway, Lambda, SQS, and DynamoDB—on a developer’s machine, teams can simulate production-like environments without touching the cloud.
This approach transforms the development process. With LocalStack, engineering teams can:
As Kannan demonstrated live, LocalStack acts as the cloud’s stunt double—allowing developers to build, test, and debug microservices entirely offline, with all the agility of the real AWS stack.
The session was met with overwhelming enthusiasm. Attendees shared how seeing microservices deployed, tested, and validated locally reshaped their approach to cloud development. Many cited the practicality of the demo, the clarity of real-world examples, and Kannan’s ability to connect deep technical insights with everyday developer challenges.
Beyond the conference, the concept resonated because it represents a shift in how cloud-native teams think about efficiency.
Research indicates that local AWS emulation can:
For large engineering teams, those gains translate to thousands of hours saved each year—while reducing production risks through consistent, reproducible testing environments.
LocalStack is more than a development convenience; it’s part of a larger cloud-native maturity model that prioritizes speed, cost control, and reliability.
At ConcertIDC, we integrate these principles into our daily work. Our teams specialize in custom software development and cloud-native architecture, helping enterprises modernize their systems, migrate securely to the cloud, and optimize operational costs through more innovative engineering practices.
By combining frameworks like LocalStack with DevOps automation, CI/CD orchestration, and containerized microservices, we help clients:
Whether you’re exploring a complete rebuild or optimizing existing pipelines, our cloud-first strategies empower organizations to innovate faster—without compromising reliability.
TechXConf 2025 brought together 40+ speakers, 30+ sessions, and more than 3,000 participants, making it one of the premier technology gatherings in Asia. The event highlighted the next wave of Generative AI, Cloud Computing, and DevOps innovation, providing a platform for the global developer community to exchange ideas, code, and visions.
We’re grateful to the organizers, speakers, and attendees who made this year’s event so impactful. The conversations started at TechXConf continue to shape the future of cloud-native development, and we’re proud to contribute to that dialogue.
For organizations pushing toward cloud-first strategies, the lesson is clear: innovation doesn’t have to come with unnecessary cost or complexity. Tools like LocalStack—and the engineering mindsets behind them—enable teams to move faster, safer, and smarter.
ConcertIDC remains committed to driving that transformation: helping companies modernize with confidence and lead with technology that works as hard as they do.
