Intelligent Caching for CI/CD Build Optimization | Harness Blog

‍ We've all been there. You push a PR, grab coffee, check Slack, maybe start a side conversation — and your build is still running. Multiply that across a team of 50 engineers, and you're looking at hours of lost focus every single day. Slow CI/CD builds don't just waste time. They generate a steady stream of "CI is slow" tickets that eat into your platform team's roadmap. Intelligent caching is one of the fastest ways to break that cycle.

Parallel Execution in Modern CI: Best Practices & Results | Harness Blog

Definition: Parallel execution in CI is the practice of running independent build, test, or deployment tasks concurrently to reduce feedback time, improve resource utilization, and control infrastructure costs. Developers often spend almost half their time waiting for builds that could be faster. Simply adding more resources is not enough. Real improvements come from planned parallelism, using concurrency together with test intelligence, caching, and strong governance.

CI Pipeline Optimization Guide for Platform Engineering Leaders | Harness Blog

Definition: CI pipeline optimization is the practice of reducing build and test time and the cost per build by running only what matters, reusing unchanged components, and enforcing standardized governance. Platform teams are wasting thousands of hours every year because their pipelines aren't working right. Developers wait 45 minutes for builds. Jenkins consumes 20% of your team's capacity on maintenance.

Architecting MCP for AI Agents: Lessons from Our Redesign | Harness Blog

-- Key Takeaways: The Harness MCP server is an MCP-compatible interface that lets AI agents discover, query, and act on Harness resources across CI/CD, GitOps, Feature Flags, Cloud Cost Management, Security Testing, Resilience Testing, Internal Developer Portal, and more. -- The first wave of MCP servers followed a natural pattern: take every API endpoint, wrap it in a tool definition, and expose it to the LLM.

The Art of Prompting in AI Test Automation | Harness Blog

E2E Testing Has a New Bottleneck, and It's Not the Code End-to-end (E2E) testing has always been the hardest part of a QA strategy. You're simulating real users, navigating real flows, validating real outcomes across browsers, environments, and data states that never hold still. Traditional test automation tackled this with scripts: rigid, deterministic sequences tied to element selectors and hard-coded values. They worked until the UI changed. Or the data changed.

Resilience Testing Is Non-Negotiable in the Enterprise SDLC | Harness Blog

Outages in distributed systems are inevitable, making resilience testing essential in the SDLC. It must be continuous, covering failures, load, and disasters. Delayed validation creates “resilience debt,” increasing risk. A holistic approach—combining chaos, load, and DR testing—plus cross-team collaboration and AI-driven insights improves reliability and reduces impact. Modern software delivery has dramatically accelerated.

Knowledge Graphs: The Backbone of AI-First Software Delivery | Harness Blog

--- ‍Key Takeaways --- AI can generate code in seconds. It still can’t ship software safely. That gap isn’t about model quality or prompt engineering. It’s about context, and most software organizations don’t have a system that accurately reflects how pipelines, services, environments, policies, and teams actually relate to each other. Without that context, AI doesn’t automate delivery. It amplifies risk.

Securing AI and Securing With AI: AI Security from Code to Runtime With Harness | Harness Blog

AI is changing both what you build and how you build it - at the same time. Today, Harness is announcing two new products to secure both: AI Security, a new product to discover, test, and protect AI running in your applications, and Secure AI Coding, a new capability of Harness SAST that secures the code your AI tools are writing.

The Agent-Native Repo: Why AGENTS.MD is the New Standard | Harness Blog

This is part 1 of a five-part series on building production-grade AI engineering systems. Across this series, we will cover: Most teams experimenting with AI coding agents focus on prompts. That is the wrong starting point. Before you optimize how an agent thinks, you must standardize what it sees. AI agents do not primarily fail because of reasoning limits. They fail because of environmental ambiguity.

API Failure: 7 Causes and How to Fix Them | Harness Blog

APIs have revolutionized how web and web app developers interact with data, whether for personal use or business. One of our most profound responsibilities as API developers is to protect our endpoints from being hacked. Even with essential safeguards in place, our websites can be vulnerable. This post discusses seven causes of API failures and how to fix them.
