The lakehouse architecture was developed with the mission to combine the unstructured scale of the data lake with the structured performance of the data warehouse. This shift unified enterprise data and delivered the first true "single source of truth". But in 2026, the mission has expanded.

Retail banking is quietly undergoing one of its biggest shifts in decades. Customers no longer compare banks to other banks. They compare them to Netflix, Amazon, and every digital experience that already gets them. That expectation has changed the game. This is where AI-powered personalization in retail banking comes in. Instead of offering generic products to broad customer segments, banks can now deliver hyper-relevant experiences in real time.

According to SmartBear’s Closing the AI Software Quality Gap study, 93% of teams are already using AI to generate code. The same study found that 60% expect AI to produce nearly half of all code within the next year. This shift in development velocity is already impacting software testing and quality. Most teams say application quality is suffering, and 60% have experienced quality issues in the past year because development is moving faster than testing can keep up.

There is a moment most travel platform teams are now experiencing for the first time. The AI-powered booking assistant is live. The conversational search feature is generating rave reviews from product managers. The personalised itinerary engine is pulling data from a dozen microservices in real time. And then peak season arrives. Response times climb. The AI layer starts queuing. The booking funnel drops. Users abandon. And the engineering team realises something uncomfortable.

MCP (Model Context Protocol) is an open standard that lets AI agents connect to external tools and data sources in a consistent, secure way. We can think of the MCP as a USB-C port for AI agents. This open protocol from Anthropic (the guys who built the Claude chatbot) enables AI applications to plug into external tools without any custom glue code.
