The final day of Replay ‘25 delivered a mix of technical deep dives and real-world case studies before concluding with an unexpected twist. After two days packed with hands-on learning and insightful talks, attendees gathered for the last round of knowledge sharing focused on practical applications of Temporal.

Building for Reliability#

Temporal’s Sergey Bykov kicked off the day with an engaging comparison between application reliability and the Three Little Pigs fairy tale. He traced the evolution of reliability requirements and explained how redundancy enhances resilience while introducing new coordination challenges. This theme continued with Wise Payments’ approach to managing databases at scale. With 16 million customers worldwide and downtime tolerance measured in milliseconds, Samira El Aabidi and Yash Vanzara demonstrated how they’re using Temporal to enable self-service automation for critical database operations, integrating with AWS to handle issues with minimal human interventihttps://temporal.io//images.ctfassets.net/0uuz8ydxyd9p/3TL3BjhCiytu9sjWGz61t1/815fa609f1d3abdc2499b61a21476322/DSC_0648.jpg476322/DSC_0648.jpg" alt="DSC 0648">

Production Patterns and Enterprise Adoption#

Several sessions highlighted the journey from basic workflows to production-grade systems. Mercury’s Ian Duncan shared insights from building financial infrastructure with Temporal, focusing on testing approaches, transactional safety, and performance optimizationshttps://temporal.io//images.ctfassets.net/0uuz8ydxyd9p/w2AROBw6Ba2DKKYueBlid/e083a6793cd652933b726c5e1ba13073/DSC_0792.jpg93cd652933b726c5e1ba13073/DSC_0792.jpg" alt="DSC 0792"> Following the previous day’s product announcements, Temporal’s Drew Hoskins and Shahab Tajik introduced Worker Versioning APIs, providing guidance on implementing these new capabilities to makehttps://temporal.io//images.ctfassets.net/0uuz8ydxyd9p/6iX3iv6vjpKV6Ur8PlD19j/60b9523899bbf43ddcff7d3a031c2401/DSC_0841.jpgV6Ur8PlD19j/60b9523899bbf43ddcff7d3a031c2401/DSC_0841.jpg" alt="DSC 0841"> Enterprise adoption stories came from companies like Nutanix, where Bharadwaj Embar shared three years of production experience using Temporal for platforms engineering. His examples ranged from simplified Kubernetes workload management to access control systems, demonstrating how Temporal solves problems at multiple layers of their stack.

Critical Systems and Cross-Boundary Orchestration#

Some of the most compelling stories came from organizations using Temporal for mission-critical applications. Verkada’s Sai Teja Reddy Moolamalla explained how their cloud-based alarm system uses Temporal to build durable alarm responses for AI-powered security systems, where relhttps://temporal.io//images.ctfassets.net/0uuz8ydxyd9p/5L1NHreBtAghl8TlOwhZZf/0af1f304ccab681c9b49dac5113b21df/DSC_1255.jpgydxyd9p/5L1NHreBtAghl8TlOwhZZf/0af1f304ccab681c9b49dac5113b21df/DSC_1255.jpg" alt="DSC 1255"> One highlight was Miro’s presentation with Temporal’s Phil Prasek on Temporal Nexus. Pedro Albuquerque and Juan Agustín Moyano explained how they built a self-healing control plane for storage infrastructure, then leveraged Nexus to orchestrate cross-region data migrations without direct network connectivity.

KOHO’s Ali Waseem shared a particularly relatable crisis response story, detailing how they adopted Temporal mid-flight during a critical development cycle. Their team integrated Temporal to maintain service reliability during a vendor's severe outage, turning what could have been a major incident into a non-event for their users.

Temporal Across Industries#

The technical program concluded with Check’s Sam Wilson explaining how they transformed payroll processing using Temporal. By combining microservices principles with durable execution, they’ve achieved significant improvhttps://temporal.io//images.ctfassets.net/0uuz8ydxyd9p/73DFSzcVpKWD7CWiVZQ5Ie/b8605b0515e54e5d37d93bce36e897fc/DSC_9875.jpgctfassets.net/0uuz8ydxyd9p/73DFSzcVpKWD7CWiVZQ5Ie/b8605b0515e54e5d37d93bce36e897fc/DSC_9875.jpg" alt="DSC 9875"> Other industry applications spanned pharmaceutics (Eli Lilly), telecommunications (Telenor), retail (Trendyol Group), and global infrastructure (Equinix), each demonstrating how Temporal addresses unique challenges in their respective domains.

Ending on a High Note: The Tech Roast and Afterparty#

In a fun twist, Replay ‘25 closed with the Tech Roast Show making its London debut. This comedy troupe brought sharp thttps://temporal.io//images.ctfassets.net/0uuz8ydxyd9p/73lLCEINGDzFBcA0NH6DON/e341fbffddfff62a97a8d4159e84ae01/DSC_1798.jpg The evening continued with an afterparty, where attendees had a final opportunity to network and continue discussions in a relaxed setting.

Replay ‘25 is Over, Long Live Replay ‘26!#
