SaltStack Consulting

SaltStack, now known as Salt, is an open-source configuration management and remote execution tool. It automates the deployment and management of infrastructure and software across diverse environments. Salt employs a scalable, event-driven approach, enabling fast and efficient orchestration of complex systems. Its architecture is designed to handle the management of a vast number of servers, devices, and systems with high speed and flexibility. SaltStack supports both push and pull communication models through its agentless and agent-based setups, making it adaptable to various IT environments.

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.

SaltStack (Salt) is an open-source configuration management and remote execution platform used to enforce desired state and run commands across large fleets with low latency. It is commonly chosen when teams need fast, scalable automation across mixed on-prem and cloud environments.

• High-speed remote execution enables ad hoc commands, orchestration steps, and incident response actions across thousands of nodes.
• State-based configuration management keeps systems converged to a defined configuration and reduces drift over time.
• Event-driven automation via the Salt event bus supports reactive workflows such as remediating failures or responding to monitoring alerts.
• Flexible targeting and grouping makes it practical to apply changes by role, environment, grain, pillar data, or dynamic criteria.
• Extensible modules and custom execution functions allow integrating with internal tooling, APIs, and platform-specific operations.
• Orchestration capabilities coordinate multi-step changes across services, including ordering, dependencies, and rollbacks.
• Secrets and configuration data separation through pillars supports safer parameterization across environments.
• Works across heterogeneous operating systems and infrastructure types, which helps standardize automation in hybrid estates.
• Infrastructure-as-code workflows align with version control and CI/CD practices for reviewable, repeatable changes.

SaltStack fits well for organizations that need fast remote execution plus configuration enforcement, but it requires disciplined state tree design and pillar hygiene to stay maintainable at scale. In environments where agentless operation is a hard requirement, alternative approaches may be a better fit.

Common alternatives include Ansible, Puppet, Chef, and Terraform for provisioning-focused workflows.

Our experience with SaltStack helped us build repeatable automation patterns and operational tooling that we use to help clients standardize server configuration and deploy changes safely at scale across mixed Linux environments.

Some of the things we did include:

• Designed and implemented Salt states and pillars to manage baseline OS hardening, packages, users, and service configuration consistently across fleets.
• Built reusable state modules and environment promotion workflows (dev/stage/prod) to reduce drift and make infrastructure changes auditable.
• Integrated SaltStack runs into CI/CD pipelines using GitHub Actions for linting, testing, and controlled rollouts.
• Automated secret distribution and rotation by integrating Salt with HashiCorp Vault and enforcing least-privilege access patterns.
• Implemented event-driven remediation and orchestration using Salt reactors for common operational tasks (service restarts, config regeneration, node quarantine).
• Standardized image and bootstrap workflows for cloud instances on AWS and Azure, including minion enrollment, key management, and environment targeting.
• Built high-signal monitoring hooks and operational dashboards by exporting run outcomes to Prometheus and aligning alerts to deployment risk.
• Hardened Salt masters and minions with network segmentation, key lifecycle procedures, and controlled execution policies for sensitive commands.
• Executed migrations from ad-hoc shell scripts and legacy configuration tools into SaltStack, focusing on modularization and reducing manual runbooks.
• Provided enablement for platform and SRE teams: state structure conventions, troubleshooting playbooks, and production support handover.

This experience helped us accumulate significant knowledge across provisioning, configuration management, security, and operations, and it enables us to deliver high-quality SaltStack setups that are maintainable, testable, and reliable for client teams.

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

• Review your Salt master/minion architecture, state tree layout, and environments, then deliver a prioritized assessment report with quick wins.
• Define an adoption roadmap covering repo structure, promotion strategy (dev/test/prod), operational ownership, and day-2 support.
• Implement and standardize Salt states, pillars, grains, and orchestration to automate server configuration and application deployments at fleet scale.
• Design security and compliance guardrails (RBAC, key management, least-privilege execution, and secrets handling) to reduce risk and support audits.
• Integrate Salt automation into CI/CD workflows and infrastructure-as-code practices to minimize manual changes and configuration drift.
• Improve reliability with reusable state libraries, testing patterns, and runbooks for safe remote execution and incident response.
• Optimize performance and cost by tuning targeting, batching, concurrency, and job execution to shorten runtimes and reduce resource usage.
• Troubleshoot and remediate hard issues such as non-idempotent states, ordering/dependency problems, flaky runs, and pillar/environment misconfigurations.
• Establish observability and auditability for automation outcomes using structured logging, metrics, and change trails to speed up debugging and approvals.
• Enable your team through hands-on training and pairing on Salt best practices, testing strategies, and operational workflows.
