Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" ...Mar. 24, 2017 06:00 AM EDT Reads: 8,364HTBase to Exhibit at Cloud Expo New YorkBy Elizabeth WhiteSYS-CON Events announced today that HTBase will exhibit at SYS-CON's 20th International Cloud Expo®, which will take place on June 6-8, 2017, at the Javits Center in New York City, NY.

Without both, DevOps isn't complete.

People were given time to deposit their existing currencies in the bank. Those who had unusually high volume of such currencies were supposed to declare the legal source or face stiff penalties such as 60-75% tax. The goal was to catch the money hoarders and black marketers who avoid paying taxes on such undeclared money.Mar. 24, 2017 08:00 AM EDT Reads: 746Innovation for Ongoing Digital TransformationBy David H DeansInformation technology (IT) advances are transforming the way we innovate in business, thereby disrupting the old guard and their predictable status-quo.

So, how are savvy chief information officers (CIOs) leading this transition?

Gartner recently listed blockchain as one of the ‘Key platform-enabling technologies to track.’ Approximately $1.4B has been invested in blockchain just this year, according to PwC executive Seamus Cushley. IBM announced this week a Blockchain-as-a-Service Enterprise offering at their Interconnect Conference.

Without a strategy, there is no rationale for deploying technologies. In addition, there is no rationale for digital transformation, unless there is a need for business transformation. If you believe this as we do, then strategy development will be a priority. Strategies, however, are developed under the guidance of a doctrine. The purpose of a doctrine is to create a high level understanding of what we we want to achieve with our strategy, and the concepts that must be employed to achieve it. An organization's doctrine will guide strat...Mar. 23, 2017 03:45 PM EDT Reads: 557Whose Data Is It?By William SchmarzoMany times, sports have been at the leading edge of data analytics. The book “Moneyball” was one of the first popular books to bring the basic concepts behind data analytics and data science to the general audience. Fantasy leagues, sabermetrics and even games like “Strat-O-Matic” baseball and basketball provided an introduction into basic statistical concepts. And it now seems that sports, in this case the National Basketball Association (NBA), are breaking new ground with another data analytics topic: who owns the data? The National Basketball Players Association recently banned NBA teams...Mar. 23, 2017 03:30 PM EDT Reads: 1,354IT in the Age of Digital Transformation By Dynatrace BlogNext month will mark the 47th anniversary of Apollo 13.

I also know how an organization’s digital transformation can generate similar reactions!
Apollo 13 was likely a casualty of the space program’s incredibly aggressive schedule. NASA, with U.S. political and military leaders, was motivated by competition from the U.S.S.R. and fear of the potential consequences of not being first.

Last weekend I opened the website https://rundexter.com/bot and developed a bot, which I then integrated with Twilio for messaging. I named it BeccaBot after our daughter. Just to be clear, her name is Becca, not Bot. It was a bot designed purely to freak-out our daughter. It was highly successful. Here are some things I learned.
You tell the bot to look for specific words or even phrases and then act upon them in specified ways. You can answer with text, or a website link, or an image, etc. You can ask for a name, and program the bot to remember the name.Mar. 23, 2017 12:15 PM EDT Reads: 1,744The IoT: Intelligent InfrastructureBy James CarliniIn the age of global cyberattacks, corporate enterprises and government agencies that have some type of cloud-based network solutions should be looking at a strategic design focus that guarantees a very secure intelligent infrastructure unsusceptible to cyberattacks or natural disasters.
Hardening an organization’s data center as well as its networks (and clouds) is a critical step to ensuring its business continuity. In today’s corporate business environment, many organizations cannot survive if their core applications are out-of-service for a couple of days.

In a recent interview with a reporter from the Bergen Record, Kellyanne Conway was asked about surveillance. She responded: “There are many ways to surveil each other now, unfortunately. There was an article this week that talked about how you can surveil someone through their phones, certainly through their television sets, any number of different ways. And microwaves that turn into cameras, et cetera.

I think the heart of that question really boils down to this: What are the differences between big data (which is analyzing large amounts of mostly human-generated data to support longer-duration use cases such as predictive maintenance, capacity planning, customer 360 and revenue protection) and IOT (which is aggregating and com...Mar. 22, 2017 05:00 PM EDT Reads: 2,967Life After the Robot ApocalypseBy Shelly PalmerTwo weeks ago, I compiled a list of the 5 jobs robots will take first.

Both previous essays are about robots replacing human workers who do cognitive nonrepetitive work (such as middle managers, salespersons, tax accountants, and report writers) that most people do not believe robots will be able to do any time soon. For those essays, I defined robots as technologies, such as machine learning algorithms running on purpose-built computer platforms, that have been trained to perform tasks that currently require humans to perform.
