XLSMART and Tencent Cloud successfully complete a large-scale AI-driven cloud transformation project | News

Tencent Cloud, the cloud business of global technology company Tencent, has successfully helped leading Indonesian telecom operator XLSMART complete a large-scale public cloud migration transformation project. The transformation was driven by XLSMART’s long-term digital modernization strategy, with Tencent Cloud serving as the strategic cloud technology partner. The project will span four and a half months and marks a groundbreaking industry practice using artificial intelligence (AI) to improve the efficiency of cloud migration.

In the process, Tencent Cloud developed more than twenty cloud migration “skills,” jointly powered by Tencent’s coding agent, CodeBuddy, and its AI agent workspace, WorkBuddy. From resource discovery to final transition, Tencent’s AI capabilities have significantly increased the overall efficiency of the migration team. This large-scale operation seamlessly migrated 1,200 microservices, 1,100 APIs and 900 business interfaces, securely transferring over 15 TB of core data.

Established in April 2025 through the landmark merger of XL Axiata and Smartfren, XLSMART has grown into a leading telecom operator in Indonesia. Jointly owned by Indonesia’s Sinarmas Group and Malaysia’s Axiata Group, the company serves a massive user base of more than 69 million people nationwide, including mobile communications, home broadband and digital business services. As XLSMART navigated post-merger integration, however, it faced steep technical hurdles: more than 60 core applications and 1,200 microservices were spread across fragmented multi-cloud platforms, hindering unified operations and management. To address this complexity, XLSMART pivoted in December 2025, launching its strategic cloud transformation project.

However, the challenges extend far beyond technology and also concern the organizational world. More than the majority of target applications required a complete redesign or rebuild, a monumental task spread across more than ten third-party vendors. Managing this complex web of multi-vendor collaboration and multi-language coordination greatly increased the complexity of the project compared to a standard migration. XLSMART rejected a superficial lift-and-shift approach and implemented a deliberate strategy: a comprehensive architecture audit to determine what needed to be retained, modified or optimized. While this deep overhaul significantly increased pressure within a compressed timeline, driving operational efficiency became the cornerstone of the project’s success.

Instead of limiting AI to isolated tasks, Tencent Cloud integrated AI capabilities into every phase of the project, including service discovery, architecture design, environment deployment, migration cutover and system monitoring. Using tools like TokenHub, CodeBuddy, and WorkBuddy, tasks that traditionally required months of manual labor were compressed into weeks or even days. The portfolio of more than twenty skills developed during the migration process has since been consolidated into a reusable AI migration platform.

To tackle resource discovery and architectural analysis – traditionally the most labor-intensive phase of the migration – Tencent Cloud has deployed two core capabilities. The first automatically scans cross-account environments, mapping hundreds of legacy resource specifications directly to Tencent Cloud configurations to generate deployable design blueprints. The second infers application architectures from discovered assets and instantly produces Low-Level Design (LLD) specification sheets and visual architecture diagrams. This shifted the engineers’ role from tedious manual Excel logging to high-level review and refinement. Combined with supporting tools for Terraform conversion, SDK customization, and automatic generation of cutover playbooks, XLSMART unified the entire lifecycle (from discovery, design, and deployment to cutover) into a single AI-driven pipeline, delivering a significant boost in operational efficiency.

During the migration, Tencent Cloud provided more than 20 core products to XLSMART, including databases, containers, security solutions and intelligent advisors, while completing more than 200 feature developments, ensuring full adaptation to the overseas technology ecosystem and local cloud usage habits. In addition, the team introduced mature capabilities such as Database Claw, which significantly improves the efficiency of database operations through agent-based capabilities.

Thanks to the close collaboration of both teams, XLSMART successfully performed a seamless, zero-downtime migration of 1,200 microservices, 1,100 APIs and 900 business interfaces in just 4.5 months. To ensure enterprise-level resilience, Tencent Cloud went far beyond standard testing protocols, conducting deep security scans and rigorous infrastructure hardening specifically tailored to protect XLSMART’s mission-critical applications.

Poshu Yeung, Senior Vice President of Tencent Cloud, head of Tencent Cloud International, said: “This set of cloud migration skills has now been consolidated into a reusable migration platform, which will be continuously applied and refined in subsequent projects. Working with XLSMART on this industry benchmark project has been a privilege and we will continue to provide solid technical support to anchor their next phase of growth.”

Yessie D. Yosetya, President and Chief Information & Technology Officer of XLSMART, said: “This project is more than a cloud migration. It establishes a stronger digital foundation that enables XLSMART to innovate faster, improve operational resilience and continuously improve the customer experience. Together with Tencent Cloud, we have demonstrated how strong collaboration can accelerate large-scale transformation while maintaining service reliability.”

Currently, Tencent Cloud’s global footprint spans more than 80 markets and regions, supported by four consecutive years of robust double-digit growth. Leveraging its global infrastructure and integrated hardware-software synergy, Tencent Cloud delivers market-leading solutions to global enterprises, enabling their digital transformation and operational excellence. In Indonesia and across Southeast Asia, Tencent Cloud remains committed to deepening its local presence by expanding public cloud coverage and cultivating a thriving partner ecosystem. In the future, Tencent Cloud will deepen its alliances with international partners such as Sinarmas Group and Axiata Group, anchoring a sustainable and mutually beneficial digital future.
