  Terraform Cheat Sheet terraform version $ terraform version Terraform v1.0.1 on darwin_amd64 terraform init $ terraform init Ask for input if necessary. If false, will error if input was required. $ terraform init -input=false You can also change the backend details using  -backend-config  option.,  reconfigure  will reconfigure the backend, ignoring any saved configuration . $ terraform init -backend-config=PATH/TO/CONFIGURATION_FILE -reconfigure

  What is the AWS Provider? Terraform depends on plugins to interact with cloud providers such as AWS, Azure etc. One of the most widely used providers in the AWS provider. This provider interacts with many resources supported by AWS, such as AWS EC2 ,VPC, and many more. Terraform uses AWS Provider with proper credentials to connect with Amazon to manage or deploy of AWS services.

  Regions and Zones Amazon EC2 is hosted in multiple locations world-wide. These locations are composed of Regions, Availability Zones, Local Zones, AWS Outposts, and Wavelength Zones. Each Region is a separate geographic area. • Availability Zones are multiple, isolated locations within each Region.  • Local Zones provide you the ability to place resources, such as compute and storage, in multiple locations closer to your end users.  • AWS Outposts brings native AWS services, infrastructure, and operating models to virtually any data center, co-location space, or on-premises facility.  • Wavelength Zones allow developers to build applications that deliver ultra-low latencies to 5G devices and end users. Wavelength deploys standard AWS compute and storage services to the edge of telecommunication carriers' 5G networks. •   AWS operates state-of-the-art, highly available data centers. Although rare, failures can occur that affect the availability of instances that...

  AMIs  Amazon Web Services (AWS) publishes many Amazon Machine Images (AMIs) that contain common software configurations for public use. In addition, members of the AWS developer community have published their own custom AMIs. You can also create your own custom AMI or AMIs; doing so enables you to quickly and easily start new instances that have everything you need. For example, if your application is a website or a web service, your AMI could include a web server, the associated static content, and the code for the dynamic pages. As a result, after you launch an instance from this AMI, your web server starts, and your application is ready to accept requests. All AMIs are categorized as either backed by Amazon EBS, which means that the root device for an instance launched from the AMI is an Amazon EBS volume, or backed by instance store, which means that the root device for an instance launched from the AMI is an instance store volume created from a template stored in Amazon ...
