Red Hat Ansible Automation Platform

enterpriseredhat.com ↗

Ansible is an open-source automation engine, and Red Hat Ansible Automation Platform is the commercial product built on it. The Ansible documentation lists its design principles: an agent-less architecture, YAML playbooks that read like documentation, SSH access using existing operating-system credentials, and idempotence, meaning a playbook changes nothing when a system already matches the declared state. Common uses named in the documentation include maintaining system configuration, continuous deployment and zero-downtime rolling updates.

Red Hat positions the platform as an enterprise execution layer for IT operations. The product page describes an automation orchestrator for designing workflows, AIOps use cases that turn AI-driven insight into governed, automated action, security automation for incident response and compliance, infrastructure modernisation across the virtual machine lifecycle, and automation of multivendor networks across campus, branch, cloud and edge.

Three deployment options are offered. In the managed service, Red Hat runs the platform and its infrastructure outside the customer's cloud. In the managed application, Red Hat runs it inside the customer's cloud. The self-managed option suits buyers with regulatory or governance requirements that call for customisation. Supported footprints include Red Hat Enterprise Linux, Red Hat OpenShift and the AWS, Azure and Google Cloud marketplaces.

Puppet

enterprisepuppet.com ↗

Puppet, now part of Perforce, is a declarative configuration management platform that continuously enforces a desired state on managed systems. Its product page describes how the platform detects configuration changes, separates planned changes from unplanned drift, corrects drift automatically and records a run report for each correction as an audit trail.

The pricing page lists three product lines. Puppet Core provides vendor-supported, hardened builds for users of open-source Puppet, free for developers below 25 nodes and custom-priced above that. Puppet Enterprise adds a web interface, role-based access control, basic patching and management of on-premises, cloud and hybrid infrastructure. Puppet Enterprise Advanced adds advanced patching, vulnerability remediation with third-party scanners such as Nessus, AI features through Perforce Intelligence, data exports and automated reporting, and priority support.

All editions support Linux, Windows and macOS agents, and Perforce states the platform offers both agent-based and agentless architecture. Puppet Forge provides more than 7,000 ready-to-use modules. The Enterprise editions include CI/CD pipeline tooling with team workspaces, impact analysis before deployment, ServiceNow self-service and integrations with Grafana, Prometheus and Splunk. Network and edge device management is optional.

Progress Chef

enterprisechef.io ↗

Chef, owned by Progress, manages infrastructure configuration as code. Its Chef Infra product page describes three parts. Chef Workstation is the local toolkit for writing and testing cookbooks and policies, and it bundles Chef Infra Client, Chef InSpec and Chef Habitat. Chef Infra Client runs on each managed system and converges it to the state declared in the policy, correcting drift when a system diverges. Chef Automate aggregates data so teams can compare intended and actual state across systems.

Chef states that the same approach manages Windows and Linux servers on premises, ARM systems in the cloud and macOS laptops at the edge. Policies can use simple declarative resources for common tasks or be extended for unusual requirements.

The pricing page shows three plans for both SaaS and self-managed deployment. Business covers node management, job orchestration and configuration management. Enterprise adds desktop management, compliance auditing and the InSpec and Infra skills. Enterprise Plus adds continuous compliance, cloud security posture management, 50 concurrent jobs instead of 10 and longer data retention with an optional dedicated instance. Every plan includes unlimited user seats and organisation units, custom user roles and a 99.9% uptime SLA.

SS

Salt (Salt Project and VMware Salt)

open-sourcesaltproject.io ↗

Salt is a Python-based, event-driven automation framework for deploying, configuring and managing IT systems. The Salt Project documentation lists configuration management uses such as operating-system configuration, installing and configuring applications, managing servers, virtual machines, containers, databases and network devices, and preventing configuration drift. Salt also provides remote execution, orchestration, an event reactor, Salt SSH, Salt Cloud and proxy minions for network devices.

Broadcom sponsors the Salt Project and sells the commercial edition. Its documentation describes VCF Salt RaaS as an enterprise platform on top of open-source Salt with centralised job execution, role-based access control, reporting and REST APIs, and states that it manages environments from 100 to 100,000 nodes. A compliance and vulnerability service scans systems against benchmarks and remediates advisories, and requires a licence that includes the feature.

Naming has changed often. The product has been sold as Aria Automation Config and Tanzu Salt, and since October 2025 is branded VMware Salt. A Broadcom knowledge article states the earlier Tanzu Salt solution is supported until October 2028 or contract end. Buyers evaluating the commercial edition should confirm current packaging and support dates with Broadcom.

CFEngine

specialistcfengine.com ↗

CFEngine, developed by Northern.tech, is one of the oldest configuration management tools. Each managed host runs an autonomous agent that enforces policy locally. The homepage groups use cases into three areas: infrastructure automation with configuration management and CI/CD integration, security automation with patch management and hardening, and compliance automation that prevents configuration drift and produces compliance reports.

Two editions are offered. Community is open source under the GPL, runs on Linux and relies on community support. Enterprise is commercially licensed and adds Windows, AIX, Solaris and HP-UX support, the Mission Portal web interface, a reporting hub with an SQL database, REST APIs, compliance reports, a policy analyser, alerts and triggered actions, inventory and change reporting, file integrity monitoring and performance monitoring, plus technical support.

The documentation states that environments with fewer than 25 agents connecting to a policy server need no licence and have no expiry. CFEngine also offers a free assessment for Community users planning an upgrade. Professional services cover consulting, implementation, performance tuning, training and sponsored development. The homepage also describes CFEngine AI, an agent that answers questions about infrastructure by generating inspectable SQL queries and can use a local model provider.

R

Rudder

specialistrudder.io ↗

Rudder is a configuration and security automation platform for Linux and Windows systems in the cloud or on premises. Its homepage describes three solutions: security configuration management that automates and enforces settings, patch and vulnerability management with patch campaigns and CVE remediation, and policy and benchmark compliance for standards such as CIS, NIST and ISO 27001.

The pricing page lists two commercial plans. Rudder Enterprise includes security configuration management plus a choice of either patch and vulnerability management or policy and benchmark compliance, with unlimited standard support, 18 months of security patches and a six-month update window. Rudder Corporate Security Suite includes all solutions, premium support with guaranteed fix or workaround times, 24 months of security patches, a nine-month update window and a dedicated customer success manager.

Rudder defines a node as any system with a Rudder agent installed, whether a server, virtual machine, container, workstation, laptop or IoT device. Enterprise modules add change requests, relay servers, patch campaigns, micropatching, CMDB synchronisation, multi-tenancy, external authentication through LDAP, Active Directory or SSO, and a customisable interface. The open-source Rudder Core can be installed from the documentation.

AWS Systems Manager is the operations hub for AWS. State Manager, one of its tools, is described in the AWS documentation as a configuration management service that keeps managed nodes and other AWS resources in a defined state. A State Manager association is a configuration assigned to resources, such as requiring antivirus software to be installed and running or certain ports to be closed, applied on a schedule.

AWS lists uses including bootstrapping nodes with software at start-up, updating agents on a schedule, configuring network settings, joining nodes to Active Directory and running scripts on Linux, macOS and Windows Server throughout their lifecycle. Paired with Automation runbooks, State Manager can also correct drift in AWS resources: attaching IAM roles, enforcing security group rules, managing DynamoDB and EBS backups, and turning off S3 read and write permissions.

Pricing changed in 2026. AWS removed the advanced instances tier on 30 June 2026, so on-premises servers, edge devices and instances in other clouds can be registered without a per-instance charge, and moved Session Manager and Run Command on those nodes to per-use pricing from 30 September 2026.

Machine configuration is a feature of Azure Policy, formerly called guest configuration and also marketed as Azure Automanage machine configuration. Microsoft Learn describes it as a native way to audit or configure operating-system settings as code on Azure machines and on hybrid machines connected through Azure Arc. Configurations can cover operating-system settings, application configuration or presence and environment settings, and can be applied per machine or at scale through Azure Policy.

Microsoft names two scenarios. In configuration management, a server is represented completely as code in source control. In compliance, settings such as TLS 1.2 are audited on existing machines and enforced on new ones as they are deployed. Each assignment uses one of three modes: Audit only reports state, Apply and Monitor applies a configuration and watches for changes, and Apply and Autocorrect returns the machine to conformance when drift occurs.

Supported systems include recent Windows Server and Windows client versions and major Linux distributions such as Ubuntu, Debian, Red Hat Enterprise Linux, AlmaLinux, Oracle Linux and Azure Linux. Results appear on the Guest assignments page and in Azure Policy compliance details. Microsoft states machines already managed by Azure Automation state configuration are not billed again.
