Exploring the Landscape of IaC Tools
The IaC paradigm is widely embraced in modern software development, offering a range of tools for deployment, configuration management, virtualization, and orchestration. Prominent containerization and orchestration tools like Docker and Kubernetes employ YAML to express the desired end state. HashiCorp Packer is another tool that leverages JSON templates and variables for creating system snapshots.
The most popular configuration management tools, namely Ansible, Chef, and Puppet, adopt the IaC approach to define the desired state of the servers under their management.
Ansible functions by bootstrapping servers and orchestrating them based on predefined playbooks. These playbooks, written in YAML, outline the operations Ansible will execute and the targeted resources it will operate on. These operations can include starting services, installing packages via the system's package manager, or executing custom bash commands.
Both Chef and Puppet operate through central servers that issue instructions for orchestrating managed servers. Agent software needs to be installed on the managed servers. While Chef employs Ruby to describe resources, Puppet has its own declarative language.
Terraform seamlessly integrates with other IaC tools and DevOps systems, excelling in provisioning infrastructure resources rather than software installation and initial server configuration.
Unlike configuration management tools like Ansible and Chef, Terraform is not designed for installing software on target resources or scheduling tasks. Instead, Terraform utilizes providers to interact with supported resources.
Terraform can operate on a single machine without the need for a master or managed servers, unlike some other tools. It does not actively monitor the actual state of resources and automatically reapply configurations. Its primary focus is on orchestration. Typically, the workflow involves provisioning resources with Terraform and using a configuration management tool for further customization if necessary.
For Chef, Terraform provides a built-in provider that configures the client on the orchestrated remote resources. This allows for automatic addition of all orchestrated servers to the master server and further customization using Chef cookbooks (Chef's infrastructure declarations).

The high speed is achieved through asynchronous task execution. The idea is that the Salt Master communicates with Salt Minions using a publish/subscribe model, where the master publishes a task and the minions receive and asynchronously execute it. They interact through a shared bus, where the master sends a single message specifying the criteria that minions must meet, and they start executing the task. The master simply waits for information from all sources, knowing how many minions to expect a response from. To some extent, this operates on a "fire and forget" principle.
In the event of the master going offline, the minion will still complete the assigned work, and upon the master's return, it will receive the results.
The interaction architecture can be quite complex, as illustrated in the vRealize Automation SaltStack Config diagram below.
When comparing SaltStack and Ansible, due to architectural differences, Ansible spends more time processing messages. However, unlike SaltStack's minions, which essentially act as agents, Ansible does not require agents to function. SaltStack is significantly easier to deploy compared to Ansible, which requires a series of configurations to be performed. SaltStack does not require extensive script writing for its operation, whereas Ansible is quite reliant on scripting for interacting with infrastructure.
Additionally, SaltStack can have multiple masters, so if one fails, control is not lost. Ansible, on the other hand, can have a secondary node in case of failure. Finally, SaltStack is supported by GitHub, while Ansible is supported by Red Hat.
SaltStack integrates seamlessly with cloud platforms, virtualization technologies, and infrastructure services.
It provides built-in modules and functions for interacting with popular cloud providers, making it easier to manage and provision resources in cloud environments.
SaltStack offers a highly extensible framework that allows users to create custom modules, states, and plugins to extend its functionality.
It has a vibrant community contributing to a rich ecosystem of Salt modules and extensions.
Chef
Chef is a widely recognized and powerful Infrastructure as Code (IaC) tool that automates the management and configuration of infrastructure resources. It provides a comprehensive framework for defining, deploying, and managing infrastructure across various platforms and environments.
Chef allows users to define infrastructure configurations as code, making it easier to manage and maintain consistent configurations across multiple servers and environments.
It uses a declarative language called Chef DSL (Domain-Specific Language) to define the desired state of resources and systems.
Chef Solo
Chef also offers a standalone mode called Chef Solo, which does not require a central Chef server.
Chef Solo allows for the local execution of cookbooks and recipes on individual systems without the need for a server-client setup.
Benefits of Infrastructure as Code Tools
Infrastructure as Code (IaC) tools offer numerous benefits that contribute to efficient, scalable, and reliable infrastructure management.
IaC tools automate the provisioning, configuration, and management of infrastructure resources. This automation eliminates manual processes, reducing the potential for human error and increasing efficiency.
With IaC, infrastructure configurations are defined and deployed consistently across all environments. This ensures that infrastructure resources adhere to desired states and defined standards, leading to more reliable and predictable deployments.
IaC tools enable easy scalability by providing the ability to define infrastructure resources as code. Scaling up or down becomes a matter of modifying the code or configuration, allowing for rapid and flexible infrastructure adjustments to meet changing demands.
Infrastructure code can be stored and version-controlled using tools like Git. This enables collaboration among team members, tracking of changes, and easy rollbacks to previous configurations if needed.
Infrastructure code can be structured into reusable components, modules, or templates. These components can be shared across projects and environments, promoting code reusability, reducing duplication, and speeding up infrastructure deployment.
Infrastructure as Code tools automate the provisioning and deployment processes, significantly reducing the time required to set up and configure infrastructure resources. This leads to faster application deployment and delivery cycles.
Infrastructure as Code tools provide an audit trail of infrastructure changes, making it easier to track and document modifications. They also assist in achieving compliance by enforcing predefined policies and standards in infrastructure configurations.
Infrastructure code can be used to recreate and recover infrastructure quickly in the event of a disaster. By treating infrastructure as code, organizations can easily reproduce entire environments, reducing downtime and improving disaster recovery capabilities.
IaC tools abstract infrastructure configurations from specific cloud providers, allowing for portability across multiple cloud platforms. This flexibility enables organizations to leverage different cloud services based on specific requirements or to migrate between cloud providers easily.
Infrastructure as Code tools provide visibility into infrastructure resources and their associated costs. This visibility enables organizations to optimize resource allocation, identify unused or underutilized resources, and make informed decisions for cost optimization.
