You know that frustrating moment when something goes wrong at work, and everyone immediately rushes to quick fixes without truly understanding the root of the problem? This is where root cause analysis (RCA) comes in to help. Let me guide you through everything you need to know about this effective problem-solving method that can transform how you address challenges in your organization.

This is the sixth post in a series about reasons to attend API Summit 2025. Check out the previous post here. APIs empower every enterprise function, starting from seamless customer experiences to efficient internal operations. As a matter of fact, APIs are the foundational technology that fuels the advancements in AI, MCP, agentic, and autonomous systems. They're the critical connective tissue that allows data, intelligence, and actions to flow securely and reliably across ecosystems.

When you build Elixir applications, you'll likely encounter scenarios where you need to handle large datasets efficiently. Whether you're importing user data from a CSV file, updating thousands of product prices, or synchronizing data from external APIs, performing operations one record at a time can quickly become a performance bottleneck. In this two-part tutorial, we'll start by exploring Ecto's powerful batch update and advanced insert capabilities for handling bulk data operations.

Every second your software slows down, you lose customers. Studies show that a delay of just 100 milliseconds can decrease conversion rates by 7%. That’s how fragile performance can be — and why software performance engineering has become a core discipline for every business serious about growth and reliability.

In my work helping teams adopt canaries, I’ve seen several recurring mistakes. Here’s a “pro tip” list to avoid them: Pro Tip: Don’t skip staging testing. Canary isn’t your only safety net—use staging to catch basic issues first. Is Your Infrastructure Ready for Global Traffic Spikes? Unexpected load surges can disrupt your services.

Traditional test scripts are too brittle for today’s fast-moving, complex systems. AI-powered agents enable a shift to scenario-based testing - high-level, reusable flows that describe user intent and behavior. Agents can help extract, generate, and evolve these scenarios, while humans guide relevance, risk, and validation. This approach improves stability, cross-platform coverage, and business alignment.

When you think about test automation, what image comes to mind? For many QA leaders, automation still means running the same scripts every night, chasing down false-positives, and fighting maintenance debt. That model served us well for a while, but it was always limited: automation only runs what humans script. The next era is about AI-powered testing. AI-powered testing doesn’t just execute predefined tasks; it generates coverage dynamically, adapting as your application evolves.

By Erez Schnaider, Technical Product Marketing Manager, ClearML The GPU-as-a-Service market is experiencing hyper growth. Yet across telecommunications companies, cloud service providers (CSPs), and enterprise organizations, GPU infrastructure has been viewed as a necessary cost center rather than a strategic asset. This perspective is changing as energy optimization technologies and multi-tenant capabilities transform GPU infrastructure into monetization engines and competitive differentiators.

APIs are most commonly and widely used in modern applications. To build the complete application frontend, backend, and databases are required, and to make proper communication, the APIs are required. But what happens when the backend isn’t ready or third-party APIs are unstable?. This is the point at which the use of API mocking comes in. By using the API mocking, developers can build, test, and debug their applications or products faster without waiting for real APIs to be live.

Deterministic masking is essential for any businesses that need to secure application data across multiple non-production environments — since it ensures data is masked consistently everywhere it appears. As CTO of Perforce Delphix, I’ve worked with many companies who need to protect sensitive data while providing realistic data for testing and development. This is especially important in industries like insurance, healthcare, and financial services.
