How to Use S3 Select to Save Time on Amazon S3

The advent of cloud computing has led to an explosion in the use of data to better understand business performance and user behavior. The combination of instantly-available compute via services like EC2 plus infinitely-scalable storage via S3 means that it’s easier than ever to store and analyze larger and larger amounts of data.

But this revolution comes at a cost. As the size of our stored data continues to grow, it becomes more and more expensive -- both in terms of processing time and in bandwidth costs -- to analyze and find insights in our data.

In this post, you will learn about S3 Select, a feature announced by AWS in 2017 to allow you to retrieve subsets of data from an object on S3. We will discuss why you would want to use S3 Select, then walk through a simple use case of how to use S3 Select with Boto 3, the AWS SDK for Python. Continue reading

Don’t Use Consumer Grade Storage for Backup. Why?

One of the most critical aspects of a sensible backup strategy is the selection of backup storage. From Google Drive to a private Minio server, the range of options is truly infinite. Some of those storage services, however, come with limitations that force you to examine professional-grade choices. Continue reading

Managing IAM Permissions in the Cloud: AWS vs Microsoft Azure vs Google Cloud

All of the major public clouds offer identity and access management (IAM) tools. The exact nature of the various cloud IAM tools vary, however. So do their names.

As a result, if you are familiar with the IAM solutions available from one public cloud, such as Amazon Web Services (AWS), it can be challenging to understand how IAM tools work on another platform, like Google Cloud or Microsoft Azure.

This article clarifies that issue by comparing the identity and access management tools and frameworks associated with each of the three major public clouds -- AWS, Azure, and Google. It identifies the key IAM-related terms and tools to know for each cloud and explains the approach that each cloud takes to managing user accounts, groups, access control and (where applicable) Active Directory integration.

Geo Redundancy Clash: Amazon S3, Microsoft Azure Blob and Google Cloud Storage

Geographical redundancy, or geo redundancy for short, is a valuable data storage strategy that can help to improve data reliability and availability. When you replicate data across multiple regions, your data is more resistant to disruptions that could cause damage to a particular data center or set of servers.

Want to take advantage of geo redundant storage but are unsure where to start? This article is for you. Below, we compare AWS replication across regions, Azure storage geo replication and the data replication features available on Google Cloud Storage.

The article’s goal is to help you understand which geo redundancy options are available from each of these three major cloud storage providers. Continue reading

Using Amazon S3 Pre-Signed URLs for Temporary Object Access

Protecting your S3 buckets is a critical security measure when using AWS. There have been numerous bad stories about unprotected S3 buckets, from established contractors like Accenture and Booz Allen Hamilton, to huge companies like Verizon Wireless and Time Warner Cable.

In this article, we'll learn how and why to use pre-signed S3 URLs to provide secure, temporary access to objects in your S3 buckets. We will discuss generating pre-signed S3 URLs for occasional, one-off use cases as well as programmatically generating them for use in yourapplication code. There are multiple code examples for each use case. Continue reading
