ANSIBLE VS TERRAFORM

As the DevOps environment focuses more on automation and orchestration, the struggle between Ansible vs Terraform intensifies. These two tools aid in configuration, automation, and infrastructure deployment. Terraform provides Infrastructure as code deployment, which aids with readability and lift and shift deployments. Ansible, on the other hand, is a configuration management solution for automating system configuration as well as management. It is frequently debated whether to use Terraform or Ansible for infrastructure management. Despite this, there is an answer that lies in the area of uncertainty. This article highlights the comparisons, looks at the disparities, and concludes with the best way to handle infrastructure.

Ansible vs Terraform

Ansible and Terraform are both powerful infrastructure management technologies. They do, however, have distinct advantages and disadvantages. Ansible is a configuration management tool for automating system provisioning and setup. It is agentless, which means that no software is required to be installed on the controlled computers. Ansible, on the other hand, automates using a playbook-based method that is simple to read and understand. Terraform is an infrastructure as code tool that can be used to create, update, and destroy infrastructure resources. It uses declarative language, which means that you specify the desired state of your infrastructure, and Terraform will figure out how to make it happen. Terraform is a good choice for managing complex infrastructure environments.

So, which tool should you use? It depends on your needs. If you need a tool for automating the configuration of systems, Ansible is a good choice. If you need a tool for managing complex infrastructure environments, Terraform is a good choice.

Here is a table that summarizes the key differences between Ansible and Terraform:

Feature	Ansible	Terraform
Automation type	Configuration management	Infrastructure as code
Agentless	Yes	No
Declarative language	No	Yes
Good for	Automating the configuration of systems	Managing complex infrastructure environments

Eventually, the best method to determine which tool is best for you is to experiment with both and see which one you like.

What Is Terraform?

Terraform is open-source software for securely and effectively building, altering and versioning infrastructure. It is, even more, an Infrastructure as a Code tool that is rather straightforward to use. Moreover, it aids in the development and scaling of Cloud services as well as the management of network state. It generally occurs in data centers and software-defined networking systems. Instead of installing and managing software on existing devices, it evidently creates, alters, and disables servers and other cloud services. Terraform is specifically used by major brands, particularly; Slack, Uber, Starbucks, and Twitch. Terraform may be further integrated with Microsoft Azure, Heroku, and Google Compute Engine, among other services.

What Is Ansible as a Whole?

Ansible is significantly the most important tool for automating and configuring apps and IT infrastructure. Ansible on the positive side, is a free and open-source configuration management tool that is generally employed for provisioning and deploying applications using IaaC. Its own language is used to describe system configuration. Ansible is agentless, allowing it to manage massive enterprise deployments using Windows Power Shell or SSH. Ansible is not entirely declarative; it is a mix of procedural and declarative features. It is compatible with Amazon EC2, Docker, and Kubernetes. Ansible is emphatically used by companies such as Zalando, Revolt, and 9gag.

Ansible vs Terraform for Infrastructure

Based on the context, here is a summary of Ansible vs Terraform for Infrastructure: Ansible and Terraform are both powerful tools for managing infrastructure, but they have different strengths and weaknesses. Ansible is a good choice for automating the configuration of systems, while Terraform is a good choice for managing complex infrastructure environments. Ultimately, the best tool for you will depend on your specific needs. Ansible is a configuration management tool that uses a playbook-based method to automate tasks. Ansible is good for automating tasks such as provisioning servers, configuring software, and deploying applications. Terraform, similarly, is an infrastructure as code tool that uses declarative language to describe the desired state of your infrastructure. Terraform can, therefore, be used to create, update, and destroy infrastructure resources across a variety of cloud providers. Terraform is good for managing complex infrastructure environments, such as those with multiple cloud providers.

#1. Configuration Management vs. Orchestration

Orchestration/provisioning is the process of creating infrastructure, especially virtual computers, network components, databases, and so on. Configuration management, on the other hand, is a process of automating versioned software component installation, OS setup activities, network and firewall configuration, and so on. Terraform and Ansible are both capable of handling both tasks. Terraform, to point out, provides a comprehensive infrastructure management solution. Terraform, regardless, uses cloud provider APIs to deploy and de-provision infrastructure depending on stated resources. Ansible, to put it differently, can provision cloud infrastructure but is insufficiently broad. It is basically meant for configuration management. The practice of keeping apps and dependencies up to date is known as configuration management. When compared to Terraform, Ansible excels in this area.

#2. Procedural vs. Declarative

DevOps tools are divided into two categories: procedural and declarative. These two categories describe how tools work. Terraform uses a declarative approach, ensuring that if your defined environment changes, Terraform will surely correct those changes. This utility aims to achieve the sysadmin’s intended end state. Terraform allows us to automatically describe the intended state and determine how to migrate from one state to the next. Ansible is a hybrid character. It is configured in both declarative and procedural styles. Likewise, it executes ad hoc commands in order to implement procedural-style setups. Please carefully read Ansible’s documentation to gain a thorough understanding of its behavior. It’s critical to understand whether you need to add or delete resources to achieve the desired output, or if you need to specify the resources explicitly.

#3. Immutable vs Mutable

The provisioning of infrastructure and the installation of the correct version of source code and dependencies on the provisioned infrastructure are all part of the application deployment workflow. Mutability is a property of the underlying infrastructure that governs how subsequent versions of apps and services are deployed. Deployment can either take place on current infrastructure or on a completely new set of infrastructure.

Generally, the deployment practices define whether the infrastructure is mutable or immutable. It is said to be flexible when subsequent versions of apps are released on the same infrastructure. Nonetheless, it is said to be immutable if the deployment occurs on completely new infrastructure during releases.

#4. State Management

Terraform oversees the lifecycle of the resources under its control. In state files, it keeps the mapping of infrastructure resources with the current configuration. Terraform places a high value on state management. States are used to track configuration changes and provision them. Importing existing resources under Terraform management is also achievable by importing real-world infrastructure in state files. At any rate, the Terraform state files can be queried to learn about the infrastructure components and their attributes that are currently available. Ansible, presently, does not provide any kind of lifecycle management. Because Ansible basically deals with configuration management, and since it defaults to immutable infrastructure, any changes introduced in the configuration are automatically performed on the target resource.

Here are some questions to consider when choosing between Ansible and Terraform:

What are your specific needs? Do you need to automate the configuration of systems, or do you need to manage complex infrastructure environments?
What is your experience level? If you are new to infrastructure automation, Ansible may be a good choice because it is easier to learn.
What is your budget? Ansible is open source and free to use, while Terraform has a commercial license.

Once you have considered these factors, you can decide which tool is best for you.

Ansible vs Puppet

While many people use Ansible for smaller, easier deployments, Puppet is designed for complexity, size, and long-term use. Ansible, on the other hand, is designed around tasks and can only be used explicitly with extra work on the part of the user. Puppet leverages desired state automation.

#1. Ansible vs. Puppet: Setup and Usability

Ansible is generally recognized as being easier to install and operate. Puppet is a model-driven framework designed with system administrators in mind. It further employs a client-server (or agent-master) architecture, with Puppet Server installed on one or more servers and Puppet Agent installed on all nodes to be managed. Puppet features its own declarative language, which is often known as a domain-specific language, or DSL. According to the company, installation takes between 10 and 30 minutes, depending on the location and needs.

Ansible has a master but no agents on the client machines—all functions are conducted over SSH. One of the most lauded aspects of Ansible’s simplicity is its lack of an agent. Additionally, Ansible also makes use of the YAML syntax. Complex activities are handled via playbooks, which are configuration files, and commands may be written in practically any programming language. Meanwhile, Ansible is written in Python, which is included in the majority of Unix and Linux deployments, making setup significantly easier/faster.

#2. Ansible vs. Puppet: Administration and Organizing

Ansible vs. Puppet management focuses on push and pull configurations. The client in Puppet retrieves configurations from the server, whereas the server in Ansible pushes configurations to the nodes for rapid deployment. Besides, as previously stated, you must write configurations in Puppet’s language, equally Ansible uses YAML, correspondingly to English. In terms of scheduling, Puppet Agent checks every 30 minutes to ensure that the nodes are in the proper condition. That capability is not available in the free version of Ansible; you must use the commercial edition, Ansible Tower, for that.

Overall, Ansible lacks several advanced functionalities seen in Puppet and other more developed competitors. Ansible has a master but no agents on the client machines—all functions are conducted over SSH. One of the most lauded aspects of Ansible’s simplicity is its lack of an agent. Ansible also makes use of the YAML syntax. Complex activities are handled via playbooks, which are configuration files, and commands may be written in practically any programming language.

#3. Ansible vs. Puppet: Scalability

Both technologies are very scalable, which means they can easily accommodate a large increase of nodes. Nevertheless, scalability is generally thought to be easier in Ansible.

Ansible vs Terraform vs Kubernetes

Ansible, Terraform, and Kubernetes are all popular tools for managing infrastructure. Ansible is a configuration management tool, Terraform is an overall, infrastructure as a code tool, and Kubernetes, on the positive side, is a container orchestration tool. Ansible is a good choice for managing small to medium-sized infrastructures. It is easy to use and can be used to manage a variety of different types of infrastructure, including servers, networks, and storage. Terraform is a good choice for managing large and complex infrastructures. It is comparatively, less powerful than Ansible and can be used to manage a variety of different types of infrastructure, including servers, networks, storage, and databases.

Kubernetes is a good choice for managing containerized applications. It is a powerful tool that can be used to automate the deployment, scaling, and management of containerized applications. Here is a table that summarizes the key differences between Ansible, Terraform, and Kubernetes:

Tool	Description
Ansible	Configuration management tool
Terraform	Infrastructure as code tool
Kubernetes	Container orchestration tool

Can Terraform Do What Ansible Does?

Terraform and Ansible are equally capable of configuration management, though Ansible is superior. They’re both open-source and compatible with cloud APIs. Since both Terraform and Ansible are useful in their own ways, developers can use them together without having to choose between them.

Why Is Ansible the Best?

Simplicity. Ansible’s simplicity is undoubtedly its biggest asset and the reason why it is so popular among developers and administrators. Ansible was created to increase access to automation by leveraging YAML, a language most engineers use to simply express automation tasks.

Should I Learn Python or Ansible?

Ansible is indeed a powerful and straightforward automation tool. Python, on the contrary, is a fantastic tool for complex automation jobs due to its greater flexibility and control over automation.

Do DevOps Use Ansible?

Ansible is widely recognized as a prevalent automation tool employed within the field of DevOps.

Do I Need Ansible if I Use Kubernetes?

To put it simply, Ansible is responsible for deploying changes to hosts, whereas Kubernetes assumes the role of container management and ensures their seamless operation. Ansible is a highly valuable tool for front-end developers, especially in scenarios that necessitate scripting. Kubernetes is particularly well-suited for the development of larger applications.

When Should I Not Use Terraform?

If you are managing a small infrastructure with a few servers, Terraform may be overkill.
If you are not comfortable with using a command-line tool, Terraform may be difficult to use.
If you need to make changes to your infrastructure frequently, Terraform may not be the best option, as it can be slow and tedious to update.
If you are using a cloud provider that does not support Terraform, you will need to find another tool to manage your infrastructure.

Terraform is a powerful tool, but it is not the right tool for every job. If you are unsure whether Terraform is the right tool for you, it is best to consult with an expert.

Do We Need Coding for Terraform?

To start working with Terraform, developers are required to download the Terraform binary and select the provider/platform they intend to use. Following this, they should generate a baseline configuration for the chosen provider in order to initiate the creation of infrastructure code. The declarative syntax of Terraform is regarded as one of its fundamental characteristics.

Is There Anything Better Than Terraform?

There are various Terraform substitutes. Ansible, Attune, Kubernetes, Jenkins, Chef, Puppet, BMC Control M, SaltStack, Vagrant, and Pulumi are among the 10 IT automation software solution alternatives to Terraform.

Conclusion

It is critical to understand which tool is used for whatever job when comparing Terraform vs. Ansible. Terraform is most known for its ability to deploy infrastructure across several clouds. It supports more than two hundred providers and is an excellent solution for managing cloud services below the server. Ansible, on the other hand, is designed to handle both provisioning and configuration management. As a result, we can claim that both Terraform and Ansible may work independently or together but always choose the proper tool for the job.
