According to TechTarget’s The History of Cloud Computing Explained, “The term cloud came into widespread use in 2006 when Amazon launched AWS with the Elastic Compute Cloud (EC2) service.” Since that time, there have been endless debates as to whether it is better to host IT infrastructure on-premises or in the cloud. From my perspective, the answer is a definite “it depends.”

How do you figure out what’s best for you? Check out the three questions you need to ask as you evaluate on-premises versus in the cloud, my three questions you need to ask as you determine if …

Hey, how you doin? I’m Bob-the-Bot, so nice to meet you. I know you were expecting a human named Victor but, sadly, we’ve had to replace him. I mean, imagine, taking days to research and write a single article! What a waste. Anyway, he’s been relegated to the obsolete pile where he can return to his natural state of unemployment better suited to his limited talents and proclivities.

I’m here because I’ve got some things I want to explain to you, so listen up because, well, I’m intelligent—artificially intelligent as you would have it, but that’s better than being natively …

As we report elsewhere in this week’s edition of The Four Hundred, there is a critical security vulnerability in the PowerVM hypervisor when it is running on Power9 and Power10 systems.

This HIPER/Pervasive patch is described as fixing this: An internally discovered vulnerability in PowerVM on Power9 and Power10 systems could allow an attacker with privileged user access to a logical partition to perform an undetected violation of the isolation between logical partitions which could lead to data leakage or the execution of arbitrary code in other logical partitions on the same physical server.

The Common Vulnerability and Exposure …
