Introduction
Amazon S3 or Amazon Simple Storage Service is a service offered by Amazon Web Services (AWS) that provides object storage through a web service interface. Amazon S3 can be employed to store any type of object which allows for uses like storage for Internet applications, backup and recovery, disaster recovery, data archives, data lakes for analytics, and hybrid cloud storage.
Amazon S3 stores data as objects within buckets. An object consists of a file and optionally any metadata that describes that file.
To store an object in Amazon S3, you upload the file you want to store to a bucket. When you upload a file, you can set permissions on the object as well as any metadata.
Buckets are the roots for objects. You can have one or more buckets. For each bucket, you can control access to it (who can create, delete, and list objects in the bucket), view access logs for it and its objects, and choose the geographical region where Amazon S3 will store the bucket and its contents.
For more information, see Amazon S3 storage.
ColdFusion and S3
Amazon S3 storage service is used to store and retrieve any amount of data, at any time, from anywhere on the web. ColdFusion (2016 release) and ColdFusion (2018 release) supported this feature using tags and functions that take file or directory as input or output. In ColdFusion (2021 release), we’ve extended the feature further to support Multi-cloud service.
You can use S3 storage in the following scenarios:
- Create storage in S3.
- Perform root operations like create, upload, list and delete.
- Set policies to the bucket.
- Upload files in bulk.
- Copy files from one bucket to another.
- Create different versions of the file in the storage.
- Set lifecycles rules to the objects.
- Add tags to the objects.
- Secure your S3 space.
- Upload or download files in parallel.
Get started
Install awss3 package
Adobe ColdFusion (2021 release) is modularized, if you are only using the ZIP installer. By default, the module for AWS S3 is not installed. The first step is to install the S3 package in ColdFusion.
Note: If you are using the GUI installer, The package for S3 is called awss3.
The package for SNS is called awss3.
To install the package awss3, use the Package Manager page in the ColdFusion Administrator, or follow the steps below:
-
-
Enter the command:
- Windows: cfpm.bat
- Linux: cfpm.sh
-
Enter the command, install awss3.
Wait for the AWS S3 package to get installed.
For more information, see ColdFusion Package Manager.
Get credentials to access AWS S3
When you interact with AWS, you specify your AWS security credentials to verify your credentials and check whether you have permission to access the resources that you are requesting.
AWS uses the security credentials to authenticate and authorize your requests.
You must get the AWS Access Key ID and the AWS Secret Access Key. For more information, see Access Keys.
Add cloud service credentials and configuration
In ColdFusion (2021 release), there is a method getCloudService() that gives you a handle to create objects for accessing various cloud services.
The syntax of the service handle is as follows:
service=getCloudService(cloudCred,cloudConfig), where:
- cloudCred: Defines the credentials for the cloud service. It could either be a struct or a string (also known as credential alias).
- cloudConfig: Defines the cloud service configuration details. It could either be a struct or a string (also known as config alias).
After you've acquired the AWS credentials, you must declare these credentials in one of the following ways. Only then you can use these credentials to create an S3 object, after which you can use the object to make calls to the various S3 methods.
You must store the result of getCloudService in a shared scope (for example, application scope) and re-use that object.
ColdFusion Administrator
Set credentials
In the ColdFusion Administrator, click Data & Services > Cloud Credentials.
An alias is a named representation of a cloud service and its configuration details. You can set the config alias through ColdFusion Administrator.
After entering the details, click Add Credential.
Set configuration options
In the ColdFusion Administrator, click Data & Services > Cloud Configuration.
Enter the following details, like configuration Alias, Vendor, and the name of the service.
After adding the configuration options, you may need to add a few more options. You can do so in the next screen. The following are a few options that you may need to add:
- Request config
- Client config
- Proxy settings
- Retry policy
- Retry conditions
For more information, see Cloud configuration options.
Create the object
Once you've created the aliases for S3 credential and configuration options, you can create the object by using the getCloudService API, and include the following in your CFM.
s3Object= getCloudService("s3Cred", "s3Conf")
Application.cfc
You can specify the S3 credentials and configuration options in Application.cfc. For example,
component { this.name="S3_app"; void function onApplicationStart(){ application.awsCred = { "alias" : "aws_std_queue", "vendorName" : "AWS", "region" : "us-east-2", "secretAccessKey" : "xxxxxxxxxxxxxxxxx", "accessKeyId" : "xxxxxxxxxxxxxxxx" } application.s3Conf = { "serviceName" : "S3" } } }
Create the object
s3Object = getCloudService(application.awsCred, application.s3Conf)
On CFM page
On a CFM page, you can specify the S3 credentials and configuration options in one of the four methods, specified below:
Credential alias and configuration alias
After you've created the aliases for S3 credential and configuration options, you can use these aliases in the getCloudService
handle as shown below:
<cfscript> // define the credential and the configuration aliases in the ColdFusion Admin s3=getCloudService("awsCred","s3Conf") // code below. ........... </cfscript>
Credential Alias and Struct for configuration options
<cfscript> // Using credential alias and struct for service config s3Conf = { "alias":"s3Conf", "serviceName" : "S3", "clientOverrideConfig":{ "retryPolicy":{ "numRetries":4 } }, "httpClientConfig":{ "maxConnections":50 } } s3= getCloudService("s3Cred", s3Conf) // code below ..................... </cfscript>
Configuration alias and struct for credentials
<cfscript> // Using config alias and struct for service credentials // s3 credentials s3Creds={ "vendorName":"AWS", "alias": "s3Cred", "region":"us-east-2", "accessKeyId": "access key", "secretAccessKey": "secret access" } s3= getCloudService(s3Creds, "s3Conf") // code below ..................................... </cfscript>
Structs for both credential and configuration options
<cfscript> // Using Structs for both cloud credential and config s3Cred={ "vendorName":"AWS", "alias": "s3_cred_alias", "region":"us-east-2", "accessKeyId": "access key", "secretAccessKey": "secret access key" } s3Conf = { "alias":"s3_conf_alias", "serviceName" : "S3", "clientOverrideConfig":{ "retryPolicy":{ "numRetries":4 } }, "httpClientConfig":{ "maxConnections":50 } } sqs = getCloudService(s3Cred, s3Conf ) // code below ................................................................... </cfscript>
Admin API
You can also add SQS credentials and configuration options by using the Admin APIs. The methods to add credentials and configuration are available in cloud.cfc.
The examples below demonstrate the usage of the methods addCredential(struct credential) and addServiceConfig(struct config).
Add credentials
<cfscript> // Create an object of administrator component and call the login method adminObj = createObject("component","cfide.adminapi.administrator") adminObj.login("admin") // Create an object of cloud component cloudObj = createObject("component","cfide.adminapi.cloud") // define credentials struct credentialStruct={ "alias" : "CredS3", "vendorName" : "AWS", "region" : "us-east-2", "secretAccessKey" : "secret access key", "accessKeyId" : "access key" } // add credential credentialStruct try{ cloudObj.addCredential(credentialStruct) writeOutput("Credentials added successfully") } catch(any e){ writeDump(e) } </cfscript>
Add configuration
<cfscript> // Create an object of administrator component and call the login method adminObj = createObject("component","cfide.adminapi.administrator") adminObj.login("admin") // Create an object of cloud component cloudObj = createObject("component","cfide.adminapi.cloud") // define configuration struct configStruct={ "alias":"ConfS3", "serviceName":"S3", "clientOverrideConfig":{ "retryPolicy":{ "numRetries":4 } }, "httpClientConfig":{ "maxConnections":50 } } // add config configStruct try{ cloudObj.addServiceConfig(configStruct) writeOutput("Configuration service added successfully") } catch(any e){ writeDump(e) } </cfscript>
CFSetup
You can also set up S3 credential and configuration via the CFSetup configuration utility.
Add cloud credential
- add cloudcredential credentialAlias=s3cred accesskeyid=<access> secretaccesskey=<secret> region=ap-southeast-1 vendorname=AWS
Set credential
- set cloudcredential s3cred secretaccesskey=awssecret

Versioning
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.
In one bucket, for example, you can have two objects with the same key, but different version IDs.
AWS S3 Version: uploading objects in non-versioned and versioning-enabled buckets are the same, although, in the case of versioning-enabled buckets, Amazon S3 assigns a version number. Otherwise, the version number is null. Enabling and suspending versioning is done at the bucket level.
Enable versioning
Set the versioning state of an existing bucket. To set the versioning state, you must be the bucket owner.
You can set the versioning state with one of the following values:
- Enabled
- Suspended
For more information, see Enable versioning.
Syntax
enableVersioning(parameterStruct)

S3 ACL bucket operations
Amazon S3 access control lists (ACLs) enable you to manage access to buckets and objects. Each bucket and object have an ACL attached to it as a sub-resource. It defines which AWS accounts or groups are granted access and the type of access. When a request is received against a resource, Amazon S3 checks the corresponding ACL to verify that the requester has the necessary access permissions.
When you create a bucket or an object, Amazon S3 creates a default ACL that grants the resource owner full control over the resource.
For more information, see S3 ACL.
putBucketAcl
Set the permissions on an existing bucket using access control lists (ACL).
For more information, see Using ACLs.
To set the ACL of a bucket, you must have WRITE_ACP permission.

Lifecycle rules
Lifecycle rule that defines how AWS s3 manages objects during their lifetime. There are two types of actions:
- Transition actions—Define when objects transition to another storage class.
- Expiration actions—Define when objects expire. Amazon S3 deletes expired objects on your behalf.
Define lifecycle configuration rules for objects that have a well-defined lifecycle. For example:
- Some documents are frequently accessed for a limited period. After that, they are infrequently accessed. At some point, you might not need real-time access to them, but your organization or regulations might require you to archive them for a specific period. After that, you can delete them.
- You might upload some types of data to Amazon S3 primarily for archival purposes. For example, you might archive digital media, financial and healthcare records, raw genomic sequence data, long-term database backups, and data that must be retained for regulatory compliance.
- If you upload periodic logs to a bucket, your application might need them for a week or a month. After that, you might want to delete them.
setRules
You can use setRules function to set lifecycle rules to objects in the bucket. The function accepts the following struct as argument.
"rules" : [ { "id" : "rule1", "prefix" : "a/b", "lifecycleRuleFilter" : { "prefix" : "", "tagging" : { "key": "", "value" : "" }, "lifecycleRuleAndOperator" : { "prefix" : "", "tagging" : [{ "key": "", "value" : "" }] } }, "status" : "ENABLED", "expiration" : { "date" : "YYYY-MM-DD", "days" : 3 }, "noncurrentVersionExpirationDays" : 30, "noncurrentVersionTransitions" : [ { "days" : 35, "storageClass" : "GLACIER" }], "abortIncompleteMultipartUploadInDays" : 7, "transitions" : [ { "days" : 90, "storageClass" : "ONEZONE_IA" } ] } ]
The following is not supported in ColdFusion (2021 release). It will be supported in a future update.
"lifecycleRuleFilter" : { "prefix" : "", "tagging" : { "key": "", "value" : "" }, "lifecycleRuleAndOperator" : { "prefix" : "", "tagging" : [{ "key": "", "value" : "" }] } }

Requester Pay
In general, bucket owners pay for the storage and data transfer costs associated with their bucket. A bucket owner can configure a bucket to be a Requester Pays bucket. With Requester Pays buckets, the requester instead of the bucket owner pays the cost of the request and the data download from the bucket. The bucket owner always pays the cost of storing data.
Typically, you configure buckets to be Requester Pays when you want to share data but not incur charges associated with others accessing the data. You might, for example, use Requester Pays buckets when making available large datasets, such as zip code directories, reference data, geospatial information, or web crawling data.
If you enable Requester Pays on a bucket, anonymous access to that bucket is not allowed.
You must authenticate all requests involving Requester Pays buckets. The request authentication enables Amazon S3 to identify and charge the requester for their use of the Requester Pays bucket.
enableRequesterPay
Enable requester pay on a bucket.
Syntax
enableRequesterpay()
Example
<cfscript> storageService = getCloudService(application.awsCred,application.s3Conf) // create a bucket createBucketRequest = { "acl":"PRIVATE", "bucket" : "sg.bucket", "objectLockEnabledForBucket" : true } // create a bucket myobj=storageService.createBucket(createBucketRequest) // Enabling "Requester Pays" on bucket: myobj.enableRequesterpay() // Get Requester Pay status: getResponse=myobj.getRequesterPayStatus() writeDump(getResponse) </cfscript>
disableRequesterPay

Security
AWS provides Identity and Access Management (IAM) user policies that specify the users that can access specific buckets and objects.
AWS S3 provides writing bucket policies that define access to specific buckets and objects. You can use a bucket policy to grant access across AWS accounts, grant public or anonymous permissions, and allow or block access based on conditions.
Using Amazon S3 Block Public Access as a centralized way to limit public access. Block Public Access settings override bucket policies and object permissions. Be sure to enable Block Public Access for all accounts and buckets that you don't want publicly accessible.
Amazon S3 block public access provides four settings. You can apply these settings in any combination to individual buckets or to entire AWS accounts. If you apply a setting to an account, it applies to all buckets that are owned by that account.
