On Their Own

  • Can't scale out reliably in production
  • Partial recovery from failures
  • No mechanisms to identify and call between agents
  • No built-in identity concept

Durable Agent Workflows

AI agents run as fault-tolerant, persistent workflows.

  • Automatic retries, checkpoints, and recovery
  • Long-running and asynchronous execution
  • No lost progress on crashes, deploys, or restarts

"If an agent fails, it resumes. Not restarts. Not guesses."

End-to-End Tracing

See exactly what every agent did, when, and why.

  • Full trace across workflows, tools, messages, and services
  • Deterministic replay for debugging and audits
  • Built-in correlation across agents and systems

"No black boxes. No "we think this happened.""

Session Management

AI agents need memory—and enterprises need control.

  • First-class session lifecycle management
  • Explicit state ownership and isolation
  • Safe handoff between agents and workflows

"Conversations, tasks, and context—managed, not improvised."

Pub/Sub for Agent Communication

Agents communicate through event-driven messaging, not fragile callbacks.

  • Decoupled, scalable agent interactions
  • Supports fan-out, fan-in, and async coordination
  • Built for multi-agent and multi-service architectures

"Agents collaborate without tight coupling."

Agent Identity & Zero-Trust Security

Every agent and MCP server has a cryptographic identity.

  • Mutual TLS (mTLS) by default
  • Strong authentication between agents and services
  • Secure-by-design, not bolted on later

"No shared secrets. No implicit trust. No shortcuts."

Enterprise-Ready Foundation

Built for the infrastructure realities of large organizations.

  • Portable, cloud-agnostic architecture
  • Designed for Kubernetes environments
  • Built on proven distributed systems patterns

"Deploy anywhere. Scale everywhere. Trust always."

Security

Zero-trust security for agents and MCP servers

  • mTLS everywhere
  • Identity-based agent communication
  • Audit-friendly tracing and logs
  • Production controls and policies

Solve critical use cases

Orchestrate and understand complex processes

Guarantee your applications execute workflows to completion, irrespective of crashes, outages or full cluster shutdowns. Visualize and observe every activity from start to finish.

Build autonomous AI agents without sacrificing reliability

Bring resiliency and flexibility to your agentic applications, with the LLMs of your choice.

Connect and secure apps across any platform

Safely connect all your apps and agents across clouds and regions, with no new code. Keep connectivity simple as your application scales.

Accelerate development

Achieve 30% to 50% developer velocity gains, bringing applications to production faster.

Enforce governance, enable collaboration

With enterprise access control and project structures, foster collaboration while reducing risk.

Integrate and swap cloud services and LLMs without rewrites

Abstract away the storage and state concerns to speed up development and maintain portability.

Who this is for

Enterprise AI Teams

Running mission-critical AI workflows at scale

Platform Engineers

Supporting AI adoption across the organization

Security & Compliance

Organizations that care about security, compliance, and explainability

AI-First Teams

Teams that want agent autonomy without operational chaos

Common patterns made easy

Process orchestration

Easily coordinate complex business processes, connecting services and APIs into reliable, scalable workflows without the heavy lifting of managing distributed systems.

Agentic applications

Build resilient agentic AI applications that can reason, act, and collaborate—delivering innovation without the infrastructure overhead, controlling your LLM costs and enforcing high levels of security.

Human-in-the-loop workflows

No workflow is an island. Blend automation with human decision-making by enabling approvals, escalations, and inputs directly in your workflows.

Event-driven microservices

Applications need communication and choreography. Build agile, resilient systems with event-driven microservices that decouple dependencies and scale effortlessly.

Architecture modernization
