The Real Challenge of Running Puppet Today!

Most teams believe they’re optimizing automation, but a significant amount of their time is spent maintaining the infrastructure that supports it. The supporting stack continues to grow in complexity. Teams are always in operational mode, keeping masters running, managing databases, maintaining high-availability clusters, coordinating backups, handling drift and stitching together multiple tools.

What You Are Running Today!

  • Parallel tooling stacks (Orchestrator, Bolt, Custom Scripts)
  • Agent-only + agentless forks and separate workflows
  • Evidence reconstruction for audits
  • Unpredictable wave rollouts and firefighting

The Progress Chef Operating Model

When organizations evaluate automation tools, the conversation often centers on Chef vs Puppet. Understanding the difference between Puppet and Chef automation helps teams choose the right solution for their needs. The Chef solution isn’t just another tool - it’s the model you build automation on, so your team can stop running the platform and start managing the business.

What You Get With Progress Chef!

  • SaaS-based, managed platform that gives you a single control plane
  • Compliance checks built in line with the workflows
  • Single workflow plans for agent and agentless execution across all nodes
  • Predictable, guarded and consistent rollouts

The Chef vs Puppet Comparison

When you compare Chef and Puppet, the unified control plane that the Chef solution offers stand out.
Teams often ask about the difference between Puppet and Chef when planning migrations. When evaluating automation stacks, decision-makers ask five key questions that your stack must answer. The table below helps you compare Chef and Puppet across critical enterprise requirements. Here’s how the Progress Chef 360 platform aligns - and where Puppet starts to show cracks.

Why Pivot Off Puppet?The Chef 360 PlatformThe Puppet Stack
Do you have a managed and hosted control plane?
  • SaaS and lightweight self-managed options.

Masters, DBs have to be maintained in addition to HA overhead.

Can you run both agent + agentless with one workflow?
  • One workflow definition runs across both agent and agentless nodes.

Needs separate paths and script glue is required.

Are rollouts consistent and auditable?
  • Chef enforces waves/gates/rollback logic automatically.

Manual waves, inconsistent behavior and ad-hoc rollbacks.

Does compliance live inside the change?
  • Compliance checks run as the change is happening, and Chef verifies the fix immediately.

Controls often get validated post-change and evidence is assembled later.

Are audits seamlessly combined with your workflows?
  • Each job produces one complete, signed record with everything: approvals, what ran, results and compliance checks.

Approvals in one place, logs in another, evidence is manually rebuilt.

The Chef Solution Replaces the Layers of Platform Overhead You Maintain Today With a Single, Predictable Operating Model.

SaaS-first Automation and Simplicity

With the Chef platform, you have no masters to maintain, no database tuning or high availability choreography to perform and no platform upgrades to perform. The guardrails stay the same - the burden doesn’t.

One Signed Evidence Packet

The Chef solution delivers a signed, tamper-evident evidence packet, capturing everything from approvals through execution, wave results through rollback, and compliance controls with timestamps, removing log hunts and reconstruction.

One Operating Model for Agent + Agentless

Whether a node uses Chef Infra Client or SSH/WinRM, everything follows the same plan, workflow, rollout logic and audit trail. No forks. No glue. No drift.

Guarded Rollouts with Clear Behavior

The Chef solution helps enforces predictable rollouts with automated logic: canary → waves → health gates → retries → your defined rollback step executed consistently.

Compliance In-Line with the Workflow

CIS/STIG/internal controls are tested during the change rollouts while proof is created simultaneously in the workflow, not assembled later.

Why Chef?

Zero-Trust-Aligned Agentless Automation

Chef with agentless execution enables secure remote execution via SSH or WinRM with just-in-time secrets, scoped actions and a full audit trail.

Faster Patching, Remediation and Validation

Orchestration capabilities of the Chef platform + Compliance run that gives you patch → verify → re-scan → green in one workflow.

Continuous Compliance and Audit Readiness On-Demand

Compliance checks during Chef runs maintain that every change meets CIS/STIG/internal benchmarks.

Drift Detection and Controlled Correction

Chef continuously detects configuration drift across hybrid environments and applies controlled, policy-driven corrections to keep systems aligned without surprises.

Testing Before Deployment

Validate changes in isolated environments before rollout to reduce risk and rework.

Large-Scale Rollouts Without Guesswork

Chef enforces predictable rollout behavior during waves with gates across thousands of nodes.
