AWS S3 New Updates

AWS S3 new updates includes,

1. Object Ownership.

2. S3 Access Point.

Object Ownership

Think about we have one S3 bucket and we have multiple IAM users who access the S3 bucket for read and write. When as IAM user you create bucket you become owner of your S3 bucket and then you assign multiple IAM users to access your bucket and when the same other IAM user upload any new object to your S3 bucket the owner of that object become that IAM user who uploaded the object.

Now here sometime you would like to change the access and you want as bucket owner you should be the owner of all the objects of your S3 bucket as well and to do that you have to update the S3 permission setting. Go to your S3 bucket permission tab for the same and update the setting. Here make sure you have to update the bucket policy as well to allow other AWS account/IAM-user to upload the objects.

S3 Access Point

Again similar scenario where we have one S3 bucket and we have multiple sources from where read/write of the objects need to happen and to allow that generally we create IAM user and provide the respective access and secret key to users to access the S3 and now we have other solution to have multiple S3 access point for your bucket, so that the different users/sources will use their allocated S3 access point to perform read/write with S3 bucket and the advantage is you can set all the policy on S3 access point level, so that it will be easy maintain the access for different users/sources.

To achive this, go to S3 bucket Access Point tab and create the respective access point for your differnt users.

Create new access point and provide required policy -

Now once have created the access point then you can access your access point using below URL, here update the respective placeholder as per your SWS account -

https://[access_point_name]-[accountID].s3-accesspoint.[region].amazonaws.com
