HashiCorp’s Terraform is an open-source infrastructure as code (IaC) tool. It enables you to use a declarative configuration language to define and manage your cloud infrastructure resources and services. You may use Terraform to automatically supply and manage a variety of infrastructure parts, including virtual machines, networks, storage, and more, across numerous cloud providers or on-premises environments.
1 Declarative Configuration: You identify the resources you require, their configurations, and relationships in a declarative configuration file that is often written in the HashiCorp Configuration Language, or HCL.
2 Provider Support: Numerous cloud service providers (such as AWS, Azure, Google Cloud, etc.) and other infrastructure elements (such as Docker, Kubernetes, etc.) are supported by Terraform. Terraform can be used to manage the resources and configurations that each supplier has to provide.
3 Versioning and Collaboration: Versioning and storing Terraform configurations in version control platforms like Git allows for team collaboration and preserves an audit trail of modifications.
4 Idempotency: Terraform operates under the idempotency principle, allowing you to apply the same configuration repeatedly without experiencing unintended consequences. To get the infrastructure to the desired state, Terraform will only perform the required adjustments.
5 Plan and Apply: When you modify your configuration file, Terraform can provide an execution plan that outlines the changes that will be performed to your infrastructure. After reviewing the strategy, you implemented it to bring about the desired improvements.
6 State Management: Your infrastructure’s current state is recorded by Terraform in a state file. This file aids Terraform in comprehending the configurations and resources that are currently deployed. It is crucial for updating and maintaining your infrastructure.
Compared to manual intervention, Terraform substantially simplifies the provisioning and management of infrastructure. It makes it possible to use infrastructure as code techniques, which facilitate the replication of environments, the management of modifications, and the maintenance of consistency throughout various stages of development and deployment.
1 The HashiCorp Terraform infrastructure as code (IaC) tool uses the terraform init command to initialize new or existing Terraform configurations in directories. Terraform creates the environment, downloads provider plugins, and gets the directory ready for controlling your infrastructure when you run Terraform init.
2 In HashiCorp Terraform, the terraform plan command generates an execution plan outlining the modifications Terraform will make to your infrastructure based on your existing configuration. Without actually making the changes, it demonstrates to you what steps Terraform will take to create, update, or remove resources, for example. By doing so, you may examine and confirm the modifications before implementing them in your infrastructure.
3 In HashiCorp Terraform, the changes specified in your configuration are applied to your infrastructure using the Terraform apply command. This command executes the operations required to create, update, or delete resources in accordance with your settings using the execution plan produced by Terraform plan.

Bucket owner enforced – Bucket and object ACLs are disabled, and you, as the bucket owner, automatically own and have full control over every object in the bucket. Access control for your bucket and the objects in it is based on policies such as AWS Identity and Access Management (IAM) user policies and S3 bucket policies Objects can be uploaded to your bucket only if they don t specify an ACL or if they use the bucket-owner-full-control canned ACL.
Block Public Access settings for this bucket
Public access is granted to buckets and objects through access control lists (ACLs), bucket policies, access point policies, or all. In order to ensure that public access to this bucket and its objects is blocked, turn on Block all public access. These settings apply only to this bucket and its access points. AWS recommends that you turn on Block all public access, but before applying any of these settings, ensure that your applications will work correctly without public access. If you require some level of public access to this bucket or objects within, you can customize the individual settings below to suit your specific storage use cases
Versioning is a means of keeping multiple variants of an object in the same bucket. You can use versioning to preserve, retrieve, and restore every version of every object stored in your Amazon S3 bucket. With versioning, you can easily recover from both unintended user actions and application failures.
( choose the Disable )
The default encryption configuration of an S3 bucket is always enabled and is at a minimum set to server-side encryption with Amazon S3-managed keys (SSE-S3). With server-side encryption, Amazon S3 encrypts an object before saving it to disk and decrypts it when you download the object. Encryption doesn’t change the way that you access data as an authorized user. It only further protects your data. You can configure default encryption for a bucket. You can use either server-side encryption with Amazon S3 managed keys (SSE-S3) (the default) or server-side encryption with AWS Key Management Service (AWS KMS) keys (SSE-KMS).
Amazon S3 managed keys (SSE-S3)
