How one partnership powers search for over 2 million WP Engine users

How do you make search faster, smarter, and more scalable? During our recent webinar, I sat down with Luke Patterson, senior product manager at WP Engine, and Delphin Barankanira, independent software vendor partner engineering lead and data & AI specialist at Google Cloud, to answer that question. We dug into the mechanics behind WP Engine’s ability to deliver near-instant updates to over 2 million users.
The secret to their success is a unified architecture that combines Elastic and Google Cloud. If you want to optimize your infrastructure and deploy scalable AI features, this partnership offers a clear blueprint. Let’s dive into the key insights from our conversation and explore how you can accelerate your own feature deployment.
The challenge of scale for modern software vendors
Software vendors and technology companies face a massive hurdle today. They need to provide high-precision search across huge volumes of proprietary data while ensuring peak performance and uptime for their customers. WP Engine is an in-demand platform that hosts millions of websites worldwide. For their team, search is not just a basic utility.
“We’ve evolved from being a speed, security, and hosting company into a company that provides tools to help your website succeed online. And search is one of those tools,” says Patterson.
Traditional search architectures couldn’t provide the robust, external site search solution WP Engine customers demanded. As the WP Engine team began investigating, they discovered that ineffective search was at the heart of their problems.
Patterson says, “We wanted to solve it for people using WordPress, or at least that’s how our solution started. So, the question became: how do we do this in a way that is super speedy, lightweight, and cost-efficient for our business while ensuring customers aren’t breaking the bank?”
Why unified architecture matters
WP Engine needed a flexible search solution that could handle the variety of data structures and websites they provide. Their goal was to find a tool that could map and index diverse data from any website for any owner and for any visitor — all outside of WordPress.
This is a common problem for project managers. It’s like a pendulum with ease of use on one side and the most relevant search experience on the other. As a product manager, you want ease of use, but you’re not willing to forfeit relevancy. That’s nonnegotiable.
Why choose between fast search and cost-efficient storage when you can get both? Elastic removes that exact complexity. With Google Cloud as the foundation, the platform can support a multitenant architecture while eliminating the need to cobble together different tools for search and scale.
Google Cloud Platform (GCP) provides the perfect foundation for this architecture. “Elastic is using one of the best and the greatest of Google Cloud,” says Barankanira. “The fact that it is natively built on top of GCP has provided Elastic with so much flexibility and performance. Elastic is not just another piece within a GCP environment — it is deeply integrated within the Google Cloud platform."
Future-proofing your artificial intelligence capabilities
As AI becomes the next frontier, Elastic and GCP are pioneering advancements in large language models (LLMs) to bring AI innovation to customers.
LLMs can reason, analyze context, utilize tools, call APIs, and even take action autonomously. However, their true potential is unlocked when they are anchored in customer context, ensuring their output is both relevant and actionable.
“This is where Elastic and Google Cloud really win together,” says Barankanira. “Elastic is the only partner we have right now with native grounding within Vertex AI. Because of that, it becomes effortless for customers using both Google Cloud and Elastic to develop any kind of generative AI application.”
Context is a search problem
Elastic bridges the gap between the LLM, trained on general knowledge, and your proprietary data. “AI has come and changed the world. But when I talk to customers every day who are building websites, their problems are still the same: I need people to come to my website, and once they’re at my website, I need them to convert in some way,” Patterson adds.
How do you turn website visitors into customers? With more AI agents and fewer humans browsing sites, every interaction counts. AI-powered conversational interfaces are powerful new tools for boosting conversion rates. But these tools are only as good as the context they’re given.
Giving conversational tools, chatbots, and agents the right context is a search problem. By connecting a real-time, managed vector database of your content directly to a conversational interface, you can give the LLM the context it needs to create a conversion machine.

3 ways this collaboration accelerates time-to-market
The partnership between Elastic and Google Cloud can drive real business results, such as:
Near-instant content updates: With Elastic, WP Engine customers achieve near-instant updates for website pages and product listings with response times as low as five milliseconds.
Zero downtime at scale: WP Engine handles massive traffic spikes from customers with zero downtime and seamless scaling thanks to Elastic capabilities.
- Accelerates AI deployments: WP Engine and its customers can rapidly deploy powerful AI website features, saving significant development time and infrastructure costs.
Bringing it all together for your users
Our conversation with WP Engine and Google Cloud highlighted how the right foundation is essential for innovation. “Customers don’t want to manage search, and they don’t want to manage infrastructure,” says Barankanira. “They do want access to the latest innovations. Elastic and Google are two of the most innovative companies that exist on this planet.”
