When newer versions of applications are released on the same infrastructure, it is called mutable. The deployment practices typically determine whether the infrastructure is mutable or immutable. Deployment either takes place on existing infrastructure, or we can provision a completely new set of infrastructure for the same. Mutability is an attribute associated with the underlying infrastructure that defines the way newer versions of applications and services are deployed.
Vagrant vs terraform code#
ImmutableĪpplication deployment workflow involves provisioning of the infrastructure and installing the right version of source code and dependencies on the provisioned infrastructure.
Vagrant vs terraform install#
For example, to install an Apache server on the given virtual machine as a root user, you would have to write the user creation step before defining the task for installation. The tasks will be performed in the sequence they are written. When you have to perform certain series of tasks, you define the same in the playbook. Ansible YAML scripts are procedural in nature – meaning when you write the script, it will be executed from top to bottom.Īnsible scripts are called “ ansible playbooks“. Check this Terraform import tutorial if you would like to know more about importing infrastructure under Terraform management.Īnsible uses YAML syntax to define the procedure to perform on the target infrastructure. Writing or translating existing infrastructure to code is easy in Terraform. No matter how you write the code, Terraform identifies the dependencies, and provisions infrastructure. The code could also be dispersed in multiple files. It doesn’t matter in which sequence the code is written. It uses HCL (Hashicorp Configuration Language) which is declarative in nature. Terraform is used to write Infrastructure as Code ( IaC). Terraform works best for Day 0 activities and Ansible for Day 1 and onwards activities. Logically, we can identify orchestration as Day 0 activity and configuration management as Day 1 activity. They are not flexible enough when it comes to complex infrastructure management. However, there are limitations when implementing configuration management using Terraform, and infrastructure automation using Ansible. This is where Ansible really shines as compared to Terraform.īoth the tools can perform both kinds of activities. Configuration management is a process of keeping the applications and dependencies up to date. It is mainly geared towards configuration management. Terraform uses cloud provider APIs to provision and de-provision the infrastructure based on declared resources.Īnsible, on the other hand, is also capable of provisioning the cloud infrastructure but it is not comprehensive enough. However, Terraform offers a comprehensive solution to manage infrastructure.
Vagrant vs terraform software#
Whereas, on the other hand, configuration management is a process of automating versioned software component installation, OS configuration tasks, network and firewall configuration, etc.īoth Terraform and Ansible are capable of performing both tasks. Orchestration/provisioning is a process where we create the infrastructure – virtual machines, network components, databases, etc.
