Ansible Consulting

Ansible is an open-source automation platform sponsored by Red Hat that helps teams automate IT operations such as configuration management, application deployment, and infrastructure provisioning using human-readable YAML playbooks. It is agentless in most scenarios (typically connecting over SSH for Linux/Unix and WinRM for Windows), making it straightforward to apply consistent changes across fleets of servers, VMs, network devices, and cloud resources. Common use cases include enforcing baseline configurations, orchestrating multi-step deployments, patching and compliance automation, and repeatable environment setup; functionality is extended through reusable roles and collections, an extensive module ecosystem, and optional centralized execution and RBAC via Ansible Automation Platform.

With the rise of Infrastructure-as-Code tools for provisioning infrastructure (such as Terraform), and Orchestration tools for running containers (such as Kubernetes), the need for Configuration Management decreased as it was used mostly to configure Operating Systems and provision resources.

However, there are still use-cases where companies manage the servers' Operating System directly, and they do so using Configuration Management tools.

A number of examples where managing the servers directly is required:

1. Bare-Metal or On-Premise servers
   Can't provision infrastructure using Infrastructure-as-Code tools (such as Terraform), and can't use fully-managed services for orchestration such as Kubernetes.
   In such cases Configuration Management tools will be used to manage groups of servers, install the applications' dependencies & configuration, and perhaps even install an orchestration tool such as Kubernetes.
2. Specific system requirements
   A given company might choose not to use an orchestration tool as a result of specific system requirements.
   An example would be a company that provides an SDK that communicates with the company's servers, and is implemented in clients' apps and systems, with a requirement by the clients that the SDK takes less than 5ms to respond.
   In that case the networking toll orchestration systems like Kubernetes have on every request will be unacceptable, and so that company will be forced to optimize for a very simple network topology with minimal "hops" between different parts of the system.

There is also the case where companies started with Configuration Management as their main way of building a platform for the developers, and the coupling to the Configuration Management tool became too complicated to be worth "untangling" in the short-term or even mid-term.

Ansible is an agentless automation tool used to standardize configuration management, application deployment, and day-2 operations across infrastructure. It is commonly chosen to reduce manual work, improve repeatability, and enforce consistent system state at scale.

• Agentless architecture reduces operational overhead by using SSH or WinRM without installing and maintaining client agents.
• Declarative, idempotent tasks help ensure systems converge to the desired state and make runs safe to repeat.
• YAML playbooks are readable and version-friendly, making automation easier to review, test, and maintain in Git.
• Large module ecosystem supports common platforms and services, including Linux, Windows, network devices, and major cloud providers.
• Inventory and group variables enable consistent configuration across environments while still supporting per-host differences.
• Roles, collections, and reusable playbooks encourage standardization and reduce duplication across teams and projects.
• Built-in orchestration features support multi-step workflows, such as rolling updates, dependency ordering, and coordinated service restarts.
• Secrets management integrations (for example, Ansible Vault and external secret stores) help keep credentials out of playbooks and repositories.
• Push-based execution works well for controlled change windows and ad hoc remediation, including targeted runs against specific hosts.
• Integrates cleanly with CI/CD systems to automate provisioning and deployments as part of delivery pipelines.

Ansible is a strong fit when teams want straightforward automation without running additional agents or servers. For very large fleets or event-driven automation, additional tooling such as AWX/Automation Controller, better inventory sources, and careful playbook design may be needed to manage execution time and operational complexity.

Common alternatives include Puppet, Chef, and SaltStack, as well as cloud-native options such as AWS Systems Manager for AWS-centric environments.

Our experience with Ansible across infrastructure and application operations helped us build repeatable automation patterns, reusable roles, and delivery playbooks that we now apply to client environments to reduce manual work and improve reliability.

Some of the things we did include:

• Built standardized Ansible roles for Linux baseline configuration (users, SSH, packages, time sync, logging) to keep fleets consistent across environments.
• Automated provisioning and post-provision configuration for cloud VMs, turning “day-two” tasks into predictable, version-controlled playbooks.
• Implemented application deployment workflows with rolling updates and safe rollbacks, including templated configuration and secrets handling per environment.
• Integrated Ansible into CI/CD pipelines (including Jenkins) to run linting, dry-runs, and gated deployments from pull requests.
• Connected Ansible with Terraform to separate infrastructure provisioning from configuration management while keeping end-to-end automation coherent.
• Automated Kubernetes-adjacent operations such as bootstrapping nodes, managing add-on configurations, and orchestrating cluster maintenance around Kubernetes workloads.
• Hardened servers with security baselines (CIS-style controls, SSH hardening, patching routines) and produced audit-friendly evidence via idempotent runs.
• Standardized inventory and variable management for multi-account/multi-region setups, reducing drift and improving change traceability.
• Implemented observability and operational automation by deploying monitoring agents and automating common remediation actions triggered by alerts.
• Created modular playbooks and custom filters/plugins to encapsulate organization-specific workflows and reduce duplication across teams.

This hands-on delivery work helped us accumulate significant knowledge across multiple Ansible use-cases, enabling us to deliver high-quality Ansible setups that are maintainable, secure, and scalable for client operations.

Some of the things we can help you do with Ansible include:

• Assess your current automation and Ansible codebase, delivering a prioritized review report covering reliability, maintainability, and risk.
• Create an Ansible adoption roadmap that standardizes environments, roles/collections, inventory strategy, and release workflows.
• Implement and refactor playbooks and roles for repeatable configuration management, application deployment, and day-2 operations.
• Integrate Ansible into CI/CD pipelines (e.g., Jenkins or GitLab CI) with testing, approvals, and environment promotion.
• Establish security guardrails: secrets management, least-privilege execution, hardened baselines, and compliance-friendly audit trails.
• Optimize performance and cost by reducing run times, improving idempotency, minimizing drift, and tuning parallelism and fact gathering.
• Design scalable inventories and templating patterns for multi-account/multi-region and multi-environment deployments.
• Combine Ansible with IaC and provisioning workflows (including Terraform) for consistent build-and-config pipelines.
• Improve troubleshooting and operability with structured logging, run reporting, and integrations with monitoring/alerting workflows.
• Enable your team through hands-on training, coding standards, documentation, and pair-programming to sustain best practices.
