November Product Update

🔍 What's New in Plural

As systems scale, the gap between what is defined in GitOps and what actually happens during a deployment increases, creating anxiety for every engineer on call. We're excited to announce two major breakthroughs to close that gap: Plural Sentinels, which brings automated, deep integration testing to your delivery pipeline, and Infra Research, an AI agent that turns your static code into live, queryable architecture diagrams.

Here is what we shipped in November.

Plural Sentinels

Validating infrastructure changes has traditionally been a game of manually verifying pods, tailing logs, and hoping you didn’t miss a silent failure. Plural Sentinels automate this process with a packaged, auditable, and automated testing framework.

Sentinels lets you define deep infrastructure tests as Kubernetes Custom Resources (CRDs). Unlike simple liveness probes, Sentinels can run complex validation suites (such as firing synthetic requests to an API, verifying database write permissions, or checking third-party integrations) immediately after a deployment.

With Plural Sentinels you get:

• AI-assisted validation: Sentinels can automatically inspect modified resources (like Deployments or StatefulSets) to detect configuration drift or health issues without writing custom scripts.
• Intelligent log tailing: Beyond status checks, Sentinels scan logs for error patterns during the validation window, catching issues that might not crash a pod but still degrade performance.
• GitOps native: Because they are CRDs, Sentinels live in your Git repo and integrate natively with your CI/CD pipelines, blocking bad promotions before they reach production.
• Run full Golang-defined integration tests on subsets of clusters and aggregate results.

Infra Research

The most dangerous part of any complex system is the knowledge that exists only in an engineer’s head. Plural Infra Research solves this by transforming your GitOps repositories into a live, self-documenting knowledge base.

Infra Research is a purpose-built AI agent that indexes your Kubernetes manifests and Terraform state. Instead of digging through thousands of lines of YAML to understand a dependency, you can simply ask, “How is the payment service connected to the database?”

Infra Research gives you: 

• Live architecture diagrams: The agent generates accurate diagrams (in Mermaid format) on the fly, visualizing the actual state of your infrastructure rather than a stale wiki page.
• Deep context: It understands the link between your cloud resources (Terraform) and application code (Kubernetes), allowing it to answer cross-layer questions that standard observability tools miss.
• Reduced cognitive load: It offloads the burden of mental mapping, helping new engineers onboard faster and giving senior engineers instant answers during incident response.

From the Blog

We’ve been writing about the shifting landscape of DevOps and security. Here are the latest deep dives:

• Why Cybersecurity SaaS Companies Use Plural: Security products require absolute trust, which often means strict data isolation. In this post, we explore why single-tenancy is becoming a non-negotiable requirement for cybersecurity SaaS, and how Plural enables you to offer isolated environments to every customer without drowning in operational complexity.
• Centralizing User Authentication with Okta and Plural.sh: Managing users across dozens of clusters is a recipe for security holes. This guide walks through setting up our new Okta integration to centralize identity management, ensuring that a user suspended in Okta loses access to all Kubernetes clusters instantly.
