What’s New in Nosto: 3x Faster Search and Merchandising

At Nosto, performance is everything. Whether it’s Personalized Search or browsing a category page, speed directly impacts conversions. That’s why we’ve just completed two major infrastructure upgrades designed to deliver faster, more reliable ecommerce experiences—especially for European shoppers.

Spoiler: We’re talking 3× improved latency and 70% cost savings that’ll go right back into improving our platform.

Here’s how we did it.

Migrating to Self-Hosted Elasticsearch: More Control, More Speed

Earlier this year, we migrated our search infrastructure from Elastic Cloud to a self-hosted Elasticsearch environment on AWS, with zero downtime.

Why switch?

Elastic Cloud served us well in the early days. But as Personalized Search matured and grew rapidly, we needed more flexibility, better performance, and a cost structure that scaled with us.

Thanks to our Site Reliability Engineering team, we now run Elasticsearch ourselves, and the results speak for themselves:

• ~70% cost savings for reinvestment back into the platform
• Faster query performance with optimized hardware
• Closer platform integration for quicker innovation
• Greater scalability as we grow globally
  

This wasn’t just a tech upgrade—it’s a strategic investment in speed, stability, and merchant impact.

Launching Our New EU Data Center

With our foundation in place, we took the next step: launching a new data center in the EU.

Now live, it powers Personalized Search and Category Merchandising for Europe-based merchants. The performance boost?

• 3× latency improvement
• 95th percentile latency dropped from 300ms to 100ms
• Faster, smoother search experiences
• Stronger conversion potential
  

Because in ecommerce, every millisecond counts.

What’s Next: Cross-Region Resilience

Speed is half the story. Reliability is the other.

We’re laying the groundwork for even better cross-region failover, giving better certainty that if one data center goes down, another picks up traffic seamlessly. It’s part of building a resilient, global infrastructure merchants can count on.

The Bottom Line

These infrastructure upgrades may be behind the scenes, but the benefits are front and center:

• Faster, smoother experiences for EU shoppers
• Reduced risk of slowdowns or outages
• A future-ready platform that scales with your business
  

For Nosto customers, it’s another step forward in delivering intelligent, performant ecommerce, and we’re just getting started.
