Scalability Strategies used by Paypal
Below are some of the strategies used by Paypal to achieve this milestone:
- Microservices Architecture
- Decouples functionalities into smaller, independent services.
- Allows each service to scale independently based on demand.
- Containerization
- Utilizes Docker to encapsulate microservices with their dependencies.
- Ensures consistent environments and rapid deployment, aiding scalability.
- Horizontal Scaling
- Adds more virtual machines (VMs) to handle increased load.
- Load balancers distribute traffic evenly across VMs.
- Elastic Cloud Infrastructure
- Leverages cloud services for on-demand resource allocation.
- Automatically scales resources up or down based on real-time needs.
- Load Balancing
- Employs advanced load balancing techniques to manage traffic.
- Ensures no single server is overwhelmed, maintaining performance.
- Database Sharding
- Splits databases into smaller, more manageable shards.
- Allows parallel processing and reduces bottlenecks in data access.
- Asynchronous Processing
- Uses event-driven architecture for non-blocking operations.
- Improves system responsiveness by processing tasks in the background.
- In-Memory Data Grids
- Uses distributed caching systems like Redis or Memcached.
- Enhances read performance and reduces load on primary databases.
