# Remote and Local Usage

## Local vs. remote environment

In a local environment, FASTQ.ORA files are accessible on the compute node via the file system. Cloud instances with local data, or data available via a network file system, are also considered local environments. Local environment examples include the following:

* The compute node is a laptop and files are stored on the local hard disk.
* The compute node is a cloud instance and files are copied to its local storage.

In a remote environment, FASTQ.ORA files are stored in the cloud on either AWS S3 or Azure blob.

## Remote using AWS S3

The DRAGEN ORA Helper Suite Software reuses the AWS Command Line Interface (AWS CLI) configuration. The location of a file is passed by specifying the file name as follows:

`s3://bucket/<file name>`

To make sure that the AWS CLI is configured to access your file, use the following command:

`$ aws s3 ls s3://bucket/<remote file name>.fastq.ora`

{% hint style="info" %} <mark style="color:blue;">**Info**</mark>\
Remote case on AWS S3 with DRAGEN v3.7 uses specific syntax. Refer to [oraFuse Software](https://help.ora.illumina.com/product-guides/dragen-ora-helper-suite/tools) for more information.\\

## Remote Using Azure Blob Storage

The DRAGEN ORA Helper Suite Software reuses the URI set up for your Azure Blob Storage. The location of a file is passed by specifying the file name as follows:

`https://StorageAccountName.blob.core.windows.net/<my container>/<my blob>.fastq.ora`

To make sure that the Azure CLI is configured to access your blob file, use the following command:

`export AZURE_STORAGE_CONNECTION_STRING=<yourURI> az storage blob list – container-name <myContainer>`

{% hint style="info" %} <mark style="color:blue;">**Info**</mark>\
Remote case on Azure Blob Storage is not supported on DRAGEN v3.7.\\
