Efficiency has become the need of the hour. With organizations rapidly moving to the cloud, it has become imperative to adopt the right tools and technologies for a seamless cloud migration. Terraform is one such tool which is gaining immense prominence as the go-to tool for organizations. But what exactly is this tool and how is it being leveraged by organizations – let’s delve into the overview of Terraform and its advantages.
Terraform has become a go-to tool wherein configuration scripts are written and run automatically. Terraform is essentially an Infrastructure-as-a-Code (IaC) for ensuring seamless versioning, building and changing of infrastructure. By automating the entire cycle, Terraform ensures that the existing infrastructure can be versioned and built efficiently and that the configuration scripts are easy-to-understand and deploy.
Terraform becomes key in managing the infrastructure by automating changes within the components. It quickly interprets the components which have been modified and pushes the required changes automatically. It also creates an execution plan which helps determine its listed actions for making changes to the infrastructure. It thus, becomes a seamless open-source tool to ensure efficient maintenance of the infrastructure by automating the changes to be made to it.
Advantages of Terraform
As an open-source IaC, Terraform offers an array of advantages with its simplistic features and efficient functioning. To name a few:
- Effective maintenance – Terraform creates a seamless ecosystem for maintaining the existing infrastructure by automating any changes or versioning that is needed. It thus ensures effective maintenance of the infrastructure for a robust cloud presence.
- Automated deployment – By automating the entire cycle of creating, executing, changing and versioning the infrastructure, Terraform helps organizations efficiently deploy the changes with minimal human intervention.
- Reduced time-to-deploy – In line with the aforementioned facet, Terraform exponentially reduces the time for deployment to cloud and expedites any alteration and versioning processes of the infrastructure.
- Reusable components – Terraform can be leveraged not just for multi-cloud deployment but this can easily be executed by reusing the same components or configuration file. When there are any changes made to the configuration file, the same file can then be reused for multiple scenarios.
- Customizable solutions – Terraform becomes a favorable tool for organizations – customizing solutions as per organizational needs and requirements.
- Cost-effective – Being an open-source tool, Terraform is a cost-effective apparatus to bring in end-to-end efficiency in deployment, be it for reusability, automating components or for effective maintenance.
Using Terraform on Different Clouds
Terraform is seamlessly being leveraged and integrated into different cloud platforms and technologies such as Google Cloud, AWS, Azure, Kubernetes, etc. Its implementation and integration varies as per the cloud in place but essentially involves the varied ways in which Terraform is used to create and manage instances or resources on the said cloud. From setting up a VM or Virtual Machine on any cloud to changing the configuration as per the given requirements becomes extremely easy using Terraform. An instance of the same can be found on Google Cloud’s comprehensive document. On similar lines, Terraform is leveraged within Azure to automate the infrastructure and end-to-end deployment process, manage or alter Azure’s resources, etc. With AWS, Terraform is seamlessly used to create multiple components within a huge infrastructure, ensure robust security, or to reuse variables of one module in another.
There are various ways in which Terraform is being leveraged on different clouds but its purpose remains the same – to enhance efficiency and automate, manage or version the given infrastructure as per one’s needs. Thus, for ensuring a seamless DevOps and cloud journey, Terraform becomes a key tool and catalyst by expediting the deployment processes.
