Which Cloud Do You Use?

CloudComputingWe are curious about which cloud or clouds everyone uses, as the market is rather diverse, ranging from Amazon Web Services to clouds based on OpenStack, VMware vCloud, and community clouds that meet specific needs. Are you using multiple clouds, just one cloud, or no clouds? We’d like to hear your answers to these questions. We have our heads in the clouds, as we not only write about them here but also use clouds in our daily business. This will be the first in a series of polls in which we invite you to share your opinions by voting. We’ll share the results of these polls with you in return.

Is the Cloud Just So Many Legos?

CloudComputingI was recently looking at LegoTM parts, and I started to consider the myriad of LegosTM and the broad categories they fit within. Then I had a thought. Is the cloud just so many LegosTM? SaaS, PaaS, IaaS, and DaaS are various categories of clouds. We could call them the fundamental building blocks or bricks of the cloud, and we could think of moving to the cloud as the assembly of those bricks into something usable. Or so one would think.

Data Protection: All Starts with an Architecture

VirtualizationBackupAt The Virtualization Practice, we have systems running in the cloud as well as on-premises. We run a 100% virtualized environment, with plenty of data protection, backup, and recovery options. These are all stitched together using one architecture: an architecture developed through painful personal experiences. We just had an interesting failure—nothing catastrophic, but it could have been, without the proper mindset and architecture around data protection. Data protection these days does not just mean backup and recovery, but also prevention and redundancy.  Continue reading Data Protection: All Starts with an Architecture

In the New Year, Can CISOs Move On?

VirtualizationSecurityOn the December 18 Virtualization Security Podcast, we were joined by Rafal Los (@Wh1t3Rabbit) to discuss whether it is time for CISOs to move on. Should CISOs start to look beyond simply the problems at hand? Should they drive security into all decisions made at the business and architecture levels? The discussion was mixed, to say the least.

All It Takes Is One IF Clause (Santa Clause)

agilecloudAs we wind our way deeper into the holiday season, I am reminded that all it takes is one IF clause to ruin your day. Or even to ruin your holiday, if a change was made during a continuous integration cycle. Just because we can speed up and automate tasks does not mean we always should. A case in point is the work I do writing a high-performance computing package—not Hadoop, but one that was developed by several folks for a specific bit of work that occurs billions of times a day. A fully threaded application that is massive in scale for this company, it is the fastest package in the company’s industry, and this customers lifeblood.
