Well Link Securities Holdings Limited is a leading financial and securities enterprise that provides services including brokerage, investment banking, asset management, wealth management, and diversified financial products. It leverages a strong parent company background, an international platform, a professional team, and proven innovative capabilities, earning a high reputation across Hong Kong and global markets. Well Link Securities Holdings Limited is committed to providing customers with comprehensive financial services that support wealth appreciation and effective risk management.

The requirements of Well Link Securities Holdings Limited center around ensuring the efficient, secure, and stable business operations. Its priorities included high availability, reliable load balancing during high concurrency, stronger data-security controls, efficient O&M, and real-time monitoring. However, the organization faced several critical limitations in its traditional environment:

● Stability Under High Concurrency: The traditional architecture had poor load balancing. The failure of a single server can easily interrupt services, and there was no dynamic resource allocation. It was challenging to ensure a good user experience, often leading to business losses.

● Security Management: There is a large amount of sensitive data, and the existing management efficiency is low. Security controls struggled to withstand advanced attacks and found it challenging to meet the compliance requirements across multiple regions. As a result, the risk of data leakage remained high.

● Maintenance and Monitoring: Manual operation and maintenance were costly and error-prone. Traditional monitoring was unable to provide real-time or comprehensive coverage. Problems were often discovered and resolved slowly, negatively affecting business continuity.

Well Link Securities Holdings Limited chose Alibaba Cloud for its proven expertise in supporting highly available, secure, and scalable financial systems.

Alibaba Cloud’s advanced load balancing and elastic scaling capabilities ensure seamless performance during traffic spikes, maintaining business continuity. Its comprehensive security suite, including Web Application Firewall (WAF), DDoS protection, Database Audit (DBAudit), and Bastion host, delivers multi-layered defense and meets stringent financial compliance requirements.

Furthermore, Alibaba Cloud’s automated operations and real-time monitoring improve efficiency with proactive issue detection and rapid response. This partnership empowers Well Link Securities Holdings Limited to build a resilient, future-ready digital infrastructure.

The architecture supporting Well Link Securities' migration to Alibaba Cloud focuses on high-availability load balancing, enhanced security, and automated operations and maintenance monitoring. Through the Server Load Balancer (SLB), traffic is distributed efficiently to ensure stable performance under high concurrency.

For data security, Bastionhost, Database Audit (DBAudit), Web Application Firewall (WAF), and DDoS protection form a multi-layered protection system; for automated operation and maintenance monitoring, CloudMonitor enables real-time system status monitoring, ensuring efficient operations. The architecture connects networks via Cloud Enterprise Network (CEN) and dedicated lines between Shenzhen and Hong Kong for interconnection.

Sunthy Cloud, as a cloud Managed Service Provider (MSP), provides services such as cloud migration, operations and maintenance management, and optimization consulting, helping Well Link establish an efficient and compliant cloud infrastructure. Sunthy Cloud’s role delivered measurable value in the following areas:

● Reduced IT infrastructure and O&M costs: By shifting expenditures from fixed assets to flexible cloud resources, automated operations helped lower operational costs by 15%–30%.

● Elastic scaling during trading peaks: The elastic cloud architecture increased concurrent processing capacity by 1–5x during peak periods, ensuring uninterrupted trading.

● Accelerated cloud migration: DevOps tools and migration services shortened deployment timelines from months to weeks, enabling faster modernization.

● Strengthened security and compliance: MSP services aligned with Hong Kong SFC standards, offering encryption, backup, and audit capabilities that minimized data-leakage risk.

● High availability and disaster recovery: Cloud-based disaster-recovery mechanisms reduced recovery time by 90%, ensuring 99.99% system availability even during market volatility.

Together, these improvements strengthened operational efficiency and created a sustainable competitive advantage.

Well Link Securities Holdings Limited achieved a series of high-impact outcomes that strengthened its digital core.

● Data access efficiency improved, with asset management business resuming growth
● Concurrent processing capacity increased by 1x
● User activity improved by more than 20%
● Enhanced system elasticity and real-time risk indicator analysis exceeded 92% accuracy
● Operating costs reduced by 15%
● Net brokerage business fee income grew by 36%

Well Link Securities Holdings Limited plans to deepen its collaboration with Alibaba Cloud by further optimizing its cloud-native architecture. The company aims to explore AI and big data analytics for intelligent wealth management and risk prediction.

These initiatives will advance data-driven decision-making and enable more personalized, efficient, and innovative financial services, reinforcing its leadership in digital finance.
