 Scaling hospitality dataWith open source
----------------------------------------



SiteMinder, the global leader in hospitality SaaS, connects nearly 30,000 hotels in 160 countries to a broad network of tourism platforms. From their signature bed-and-breakfasts to iconic hotel chains, SiteMinder’s platform generates $18.6 billion annually in room bookings by enabling seamless guest connectivity.

But scaling their data infrastructure to match meteoric success wasn’t easy.

"Working with Instaclustr was key to our successful migration from a legacy relational database platform to Apache Cassandra in AWS. They have the operational experience and the expertise we need to manage our Apache Cassandra database for the production clusters that underpin our core platform."

 

— **Mike Rogers**, CEO, SiteMinder

 

 

 

 

 Managing rapid growth and complexity
------------------------------------

 

SiteMinder’s rapid growth and 57.3M annual reservations created infrastructure bottlenecks. Their existing PostgreSQL database on AWS EC2 relied on manual sharding—a process that introduced management overhead, reduced scalability, and stifled innovation.

Key challenges included:



 

**Operational complexity of PostgreSQL**

Struggling to manage massive “hot table” data volumes, such as hotel inventory tables, with billions of rows.

**Write-heavy data growth**

Handling write-heavy data growth that exceeded their relational database’s capabilities.

**Distributed database adoption**

Facing significant complexity in adopting Apache Cassandra due to its distributed architecture’s operational and development requirements.

 

 

 

 Instaclustr simplifies migration
--------------------------------

 

SiteMinder needed a robust distributed database to improve performance, ensure global availability, and eliminate operational overhead while supporting scalability at pace with their growth.

After extensive evaluations, SiteMinder selected Apache Cassandra for its horizontal scalability, high write performance, and multi-data center support. Instaclustr’s expertise proved to be critical in this transformation.

Here’s how Instaclustr helped:



 

**Data modeling and migration**

Instaclustr consultants collaborated closely with SiteMinder’s team to design a scalable architecture, define data models, and craft an efficient migration strategy.

**Seamless deployment**

Instaclustr’s managed platform ensured a streamlined and reliable deployment of Apache Cassandra, eliminating the need for SiteMinder to hire additional operations staff.

**24×7 operations and support**

Instaclustr provided ongoing maintenance, real-time monitoring, and proactive support to guarantee SLA compliance and maximum uptime.

 

 

 

 "Instaclustr helped us go from infrastructure bottleneck to enabler."
