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.

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
There are three main types of backup: full, differential and incremental. And the devil, really, is in the names. Full backup means that you are performing a backup of all files each time; an incremental backup will only do new and changed files or parts of files since the last backup. Differential backup will also upload new and modified files or parts of the files, but it compares itself with the full backup.
We have a separate article on incremental backup, and now we’re going to explain how differential backup works and focus on the difference between incremental and differential backup. Continue reading
Are you switching to Microsoft's hosted business apps suite and wondering how to migrate email from Gmail to Office 365? This article discusses several solutions for automatically migrating from Google Apps to Office 365. Continue reading
Microsoft Azure and Rackspace are both major cloud computing providers with an international presence.
What are the key differences between Azure and Rackspace? How does Rackspace pricing compare to Azure pricing? Which features does the Rackspace cloud offer that are not available from Azure, and vice versa?
This article answers those questions through a comparison of Azure and Rackspace. Continue reading
Alibaba Cloud may not be the first name that comes to mind when you think of competitors to Amazon Web services (AWS). However, alongside cloud services like Azure and Google Cloud Platform, Alibaba Cloud is now trying hard to unseat AWS as the world’s leading cloud computing platform.
If you live outside of Asia and haven’t heard of Alibaba Cloud until recently, you’re not alone. Although Alibaba Cloud was founded in 2009, only a few years after AWS, it focused initially on the China market, then expanded slowly into neighbouring countries.
It was not until a major $1 billion investment in 2015 that Alibaba Cloud began operating globally. It opened its first data center in the United States the same year and arrived in Europe in 2016.
Today, it is clear that Alibaba Cloud intends to compete globally with AWS and other major cloud providers. That leaves many consumers wondering whether Alibaba Cloud computing can offer better value than AWS. This article explores that question by comparing the Alibaba Cloud computing, storage, API and other services with those of AWS. Continue reading
Rackspace and Amazon Web Services (AWS) are two of the biggest names in cloud computing. Founded in 1998 and 2006, respectively, they are also among the longest-established cloud hosting companies.
The service offerings of Rackspace and AWS don’t compete in all respects. Rackspace’s main business centers on virtual servers and cloud storage, as well as managed services. AWS provides infrastructure offerings, too, through EC2 instances. However, AWS also has a broader set of services, such as serverless computing and hosted Kubernetes. Rackspace’s offerings are not as broad in this respect. Continue reading
Looking for an open source storage solution that combines the convenience of file systems with the scalability and performance of block storage? If so, open source object storage solutions are the answer.
This article discusses and compares the offerings of several object storage vendors in the open source space. Continue reading
In a perfect world, you would have an automated data backup and recovery solution in place for all of your data so that you never need to worry about losing data.
In the real world, however, you may sometimes experience data loss without having a data backup in place. For example, you may have a disk drive that begins to fail and contains data that is not backed up, or you may accidentally delete files that have not yet been written to a backup location.
Fortunately, it is sometimes possible to recover data in situations like this. Several free data recovery software can help you to restore data even from disks that are damaged, or after you have erased data from your file system.
This article provides an overview of free data recovery tools and explains what each one can do to help you recover data after a data loss. Continue reading
There are a number of storage classes for every need and budget in Amazon Web Services cloud storage. The cheapest method to store the backup for a long time is Amazon Glacier. However, there are two different ways to upload files to that storage: direct and using the lifecycle policy. In this article, we will demonstrate why the lifecycle policy method is more practical.
