App users by country

Data Management & Storage

Shopee is massive, handling millions of transactions, searches, and users on a daily basis. To keep things working smooth, it relies on an efficient mix of database technologies and advanced data practices.

Databases Used (MySQL, Redis, MongoDB, etc.)

• MySQL is the primary relational database for structured data like product listings, order details, and user profiles. Its stability and ACID compliance make it great for transactional integrity.
• Redis is implemented for caching and session management, reduce latency and load on primary databases—just what the doctor ordered for things like cart sessions and homepage loading.
• MongoDB supports Shopee’s unstructured or semi-structured data such as logs, metadata, or even some user-generated content, offering scalability and flexibility for dynamic schema.

Real-Time Data Handling

• Shopee leverages streaming platforms like Apache Kafka or Pulsar for real-time events, from order status updates to user activity tracking.
• This real-time pipeline supports in-app notifications, fraud detection, and instant analytics for both users and admin dashboards.
• Technologies like Apache Flink or Spark Streaming can compute analytics in motion—ensuring decisions and updates are made instantly and accurately.

Data Lake and Big Data Practices

• Shopee likely operates a centralized data lake architecture (possibly built on top of Hadoop or AWS S3) to store volumes of raw data.
• A big data ecosystem powered by Hive, Presto, or Apache Spark allows teams to query, aggregate, and visualize petabytes of user behavior, logistics data, or performance logs.
• This gathers business intelligence, AI/ML models, and long-term strategic decision-making—all while maintaining separation between raw, processed, and analytics-ready data.

Cloud Infrastructure

To handle international operations, Shopee relies on a hybrid cloud strategy optimized for performance, resilience, and compliance.

Shopee’s Use of Cloud Providers (AWS, GCP, Alibaba Cloud)

• Shopee likely utilizes multiple cloud providers to diversify risk and optimize for local performance—Alibaba Cloud in China, AWS or GCP in Southeast Asia.
• Services like cloud-native databases, serverless functions, and managed Kubernetes clusters are crucial for scalability and uptime.
• Hybrid cloud deployment also helps meet regional data regulations while offering an efficient backup.

Edge Computing and CDN Strategy

• To deliver a smooth experience across countries, Shopee leverages edge computing—processing some data closer to users to reduce latency.
• Content Delivery Networks (CDNs) like Cloudflare or Akamai are used to serve static content (images, CSS, JavaScript) quickly and reliably.
• This reduces the load on backend servers and ensures faster load times even in areas with weaker connectivity.

Global Performance Optimization

• Shopee uses load balancing, autoscaling, and distributed databases to keep services quick even under pressure.
• Advanced monitoring and observability tools (e.g., Prometheus, Grafana, ELK stack) help detect issues early and keep working.
• Performance tweaks are usually customised for each market—based on local server locations, language preferences, and device types.
