When cloud object storage services were originally released, they focused on the functionality of storing objects. At the time (and is frankly still good advice) the thought was that identity is the new boundary, and that traditional network security rules make cloud things complicated. The tag-phrase says something like “Identity is the new boundary”. Over time, cloud service providers have realized that customers want to be able to take PaaS services and reduce the attack surface by limiting network access to those resources.

The last concept we are going to talk about surrounding blob access is the idea of anonymous access. Unless you’ve been hiding under a rock this past few years, public access to object storage (particularly S3 buckets) have been a common “attack” vector against companies. In the past, S3 buckets were quite easy to mark as publicly accessible, leading to lots of issues. As with everything, anonymous access is done a little bit differently in each cloud provider.

My niece is employed as a recruiter and I happened to come across a post she had shared regarding Robert Half Technology’s State of Tech Hiring in Canada. I’ve always appreciated their survey data for hiring trends and in demand skill sets. What was interesting this year is just how much the cloud skill set dominated the in demand needs as well as in demand training. If you are too nervous to follow the link I placed above (I can’t blame you), here is a summary of the survey results.

In part 1, we discussed authentication options in both AWS and Azure. In this post, we will discuss the authorization options. As described in part 1, AWS makes use of a combination of user policies and resource policies to govern access. User policies are only used if the user trying to access the objects are IAM users. In this way, cross account access is also supported. User policies are standard IAM policies.

For both AWS and Azure, a REST based API has been created to facilitate blob storage operations. The REST API has two logical components, a data plane (interacting with blobs themselves) and a management plane (interacting with the service itself). The goal of this post is to talk about access options at the data plane level.

Object storage is a general purpose term used to represent the storing of unstructured data. The goal of this post is to compare features/concepts of Azure Blob storage to AWS S3. Object Organization AWS AZURE Objects are organized in buckets Objects are organized in Accounts and Containers The term “bucket” as it relates to object storage is a term almost as old as the term “cloud computing”.
