List of the Top 3 Cloud Infrastructure Automation Software for Platform9 in 2025

Ansible serves as a powerful automation engine designed to streamline processes such as cloud provisioning, configuration management, application deployment, and inter-service orchestration, while also addressing a wide range of IT needs. Its versatility makes it a valuable tool for enhancing operational efficiency across various IT tasks.

Terraform stands out as an influential open-source tool designed for handling infrastructure as code, providing users with a uniform command-line interface to engage with various cloud services. By converting cloud APIs into clear and declarative configuration files, Terraform allows individuals to articulate their infrastructure needs with precision. Users can craft their infrastructure using these configuration files, which utilize the HashiCorp Configuration Language (HCL), making it easy to define resources through organized blocks, arguments, and expressions. Prior to executing any modifications to your infrastructure, running the terraform plan command helps confirm that the intended execution plan meets your expectations. To carry out the desired configuration, the terraform apply command enables the seamless implementation of changes across multiple cloud providers. Additionally, Terraform equips users with the ability to oversee the complete lifecycle of their infrastructure — from the creation of new resources to the management of existing ones, and ultimately the removal of those that are no longer needed, thus ensuring effective oversight of cloud environments. This comprehensive method of managing infrastructure not only streamlines operations but also minimizes the potential for errors during deployment, fostering a more reliable and efficient workflow. By adopting Terraform, organizations can significantly enhance their agility and responsiveness in a rapidly evolving technological landscape.
