Case Study: Empowering High Availability and Scalability with Multi-Master PostgreSQL on AWS

3 min read

September 14, 2024

In today’s competitive digital landscape, scalability, fault-tolerance, and high availability are essential for businesses that rely on data. When a fast-growing e-commerce platform came to Cloudivian, they were struggling with these very challenges. Here’s how we empowered them with an innovative multi-master PostgreSQL setup on AWS.

The Challenge: Overcoming Database Bottlenecks and Downtime

Our client was growing rapidly but faced a number of operational hurdles:

  • Single point of failure in their existing database setup.
  • 🛑 Frequent downtime during outages and failovers.
  • Performance bottlenecks under heavy traffic.
  • 🚶♂️ Manual failover processes, extending recovery times.
  • 🕵️ Lack of real-time visibility into database performance.

Questions to Consider:

  • Are you experiencing bottlenecks that slow your business during peak traffic?
  • Is downtime affecting your business’s ability to provide seamless service?

🛠️ The Cloudivian Solution: Multi-Master PostgreSQL Setup with Open-Source Excellence

To address these challenges, Cloudivian deployed a multi-master PostgreSQL architecture leveraging powerful open-source tools on AWS.

🔧 Infrastructure as Code with Terraform

  • Automated deployment of PostgreSQL clusters using Terraform, ensuring scalable and consistent environments on AWS.
  • AWS services like EC2, Elastic Load Balancing, and Route 53 were leveraged for a reliable and flexible infrastructure.

🔄 Multi-Master Replication with pgEdge

  • pgEdge enabled multi-master logical replication, ensuring that changes made to one PostgreSQL node were replicated across all others.
  • This provided high availability, allowing read and write operations to be handled concurrently across multiple nodes.

🔑 Automated Failover with Patroni

  • Patroni was used to manage failover and recovery, with etcd handling cluster state.
  • This enabled automated failover, reducing downtime by seamlessly switching to a healthy node in case of failure.

🖧 Load Balancing with PgBouncer and Pgpool-II

  • PgBouncer managed connection pooling, reusing database connections for efficient resource use.
  • Pgpool-II further distributed queries, offering load balancing, query caching, and replication management for optimized performance.

📊 Monitoring and Alerts with Prometheus and Grafana

Prometheus monitored database health, while Grafana provided real-time visualization and alerts, ensuring proactive issue resolution.

💾 Backup and Recovery with Barman

Barman enabled automated backup and point-in-time recovery, securing the client’s data and ensuring they could recover from any disaster.

Thought-Provoking Questions:

  • What’s your strategy for minimizing database downtime and improving system reliability?
  • Are you confident that your database infrastructure can handle future growth without compromising performance?

🎯 The Results: Scalability and High Availability in Action

Our multi-master PostgreSQL solution brought immediate and lasting benefits:

  • Zero downtime even during node failures or maintenance.
  • Enhanced performance with load distributed across multiple PostgreSQL servers.
  • Seamless scaling, allowing the client to handle increased demand without additional complexity.
  • Automated failover, minimizing manual intervention and reducing recovery times.
  • Real-time insights with continuous monitoring and alerts for faster issue resolution.
  • Comprehensive backups and fast disaster recovery through Barman.
