“The Gold Standard: MySQL Benchmarking Best Practices” gives good advice. It’s also incomplete, of course. Measurement is always valuable, in my experience. I can hypothesize a circumstance in which it only amplifies confusion, or leads to a conclusion that was obvious before-hand. That’s never happened to me, however; careful measurement that I have observed, withoutRead More

When the New York Times criticized datacenters for their wastefulness, it wasn’t just a little off-target. It entirely missed, for example, the Open Data Center Alliance‘s prediction “that the overall power savings [emphasis added] from cloud adoption could add up to approximately 45GW by 2015 … enough … to power up to 15 million homes.”Read More
I’m skeptical of IBM’s Real-time Compression Appliances. More accurately, I’m skeptical of our ability to judge them usefully. The technical summary is mouth-watering: unpack one of these boxes, plug it into your storage network, and a few seconds later the load on your storage and network plummets “by up to 80 percent”. That kind ofRead More
The “biggest cyberattacks in history” hit five US megabanks in succession last month, according to this CNN headline. While it will be hard ever to be certain about all the details–nearly everyone involved in the matter has an incentive to tell less than the whole truth–it now appears that the attacks had relatively modest impactRead More
We certainly have plenty of problems to solve in the datacenters of 2012–but nothing like what James Glanz of the New York Times portrayed last week in “Power, Pollution and the Internet” (PPI). The most sense I’ve made of this article is to read it as an investigative assignment that turned into a lifestyle piece.Read More
When we can’t have it all–and we never can–what’s worth keeping, and what worth letting go? That’s a tough question that Oracle, and all cloud customers, face in different respects this week. Oracle’s announcement this week of Oracle Application Development Framework [ADF] Essentials is a surprise I expected never to hear, for instance. Since itsRead More
Nick Heath writes too much or too little. Yes, “IT [information technology] departments needs to meet business demands or risk being demoted to a minor support role“, as his recent advisory summarizes the matter. It has always been this way, though, at least during the seven decades of electronic IT. By the 1950s, IT pioneersRead More
To make the most of “private cloud” depends on clear understanding of the technology, and how it applies to your own organization. That kind of teamwork was the advice of “Customize your APM” earlier this week, and it applies with at least equal force to the subject of private clouds. That’s the message, at least,Read More
Application Performance Management (APM) remains in its infancy. There’s no simple formula for applying it usefully; expect that you’ll need to study both APM techniques and the specifics of your own organization’s needs to fit the former to the latter. That’s part of what I read in Larry Dragich’s recent “Real-Time Monitoring Metrics – TheRead More
Dirk Nachbar just published a useful little WebLogic Scripting Tool (WLST) script to start or stop multiple WebLogic Managed Servers. A simple refactoring extends his effort to make the script a bit more compact and arguably easier to maintain. This refactoring turns up in many other scripts, far removed from WebLogic or even Python. NachbarRead More
