Driving Compute And Storage Scale Independently

While legacy monolithic applications will linger in virtual machines for an incredibly long time in the datacenter, new scale-out applications run best on new architectures. And that means the underlying hardware will look a lot more like what the hyperscalers have built than traditional siloed enterprise systems.

But most enterprises can’t design their own systems and interconnects, as Google, Facebook, and others have done, and as such, they will rely on others to forge their machines. A group of hot-shot system engineers that were instrumental in creating systems at Sun Microsystems and Cisco Systems in the past two decades have …

Afraid of floods and hackers? Put your data in space.

Satellite-based data centers with room for petabytes of data may start orbiting Earth as early as 2019. But when it comes to keeping secrets safe from the long arm of the law, the black void may not be far enough.Cloud Constellation, a startup in Los Angeles, is looking upward to give companies and governments direct access to their data from anywhere in the world. Its data centers on satellites would let users bypass the Internet and the thousands of miles of fiber their bits now have to traverse in order to circle the globe. And instead of just transporting data, the company’s satellites would store it, too.The pitch goes like this: Data centers and cables on Earth are susceptible to hacking and to national regulations covering things like government access to information. They can also slow data down as it goes through switches and from one carrier to another, and all those carriers need to get paid.To read this article in full or to leave a comment, please click here

IDG Contributor Network: 3 reasons to be a 20-something mainframer

We all know the stereotype of a mainframe programmer or admin: gray hair, graduated from college in 1965, drives a Chrysler—and is about to retire, leaving a massive hole that his employer will find difficult to fill because no one under 60 knows how to use a mainframe.Now, let’s look at another stereotype: the millennial programmer. He/she is a few years out of college, with a degree in computer science, green or blue hair, and enough student debt to sink a yacht. The usual next step is to move to San Francisco, pay $2,200 a month to live under a staircase like Harry Potter and dream of joining a company that has a one-in-a-million chance of becoming the next Google.To read this article in full or to leave a comment, please click here

What is a Failure Domain?

“No, I wouldn’t do that, it will make the failure domain too large…”
“We need to divide this failure domain up…”

Okay, great—we all know we need to use failure domains, because without them our networks will be unstable, too complex, and all that stuff, right? But what, precisely, is a failure domain? It seems to have something to do with aggregation, because just about every network design book in the world says things like, “aggregating routes breaks up failure domains.” It also seems to have something to do with flooding domains in link state protocols, because we’re often informed that you need to put in flooding domain boundaries to break up large failure domains. Maybe these two things contain a clue: what is common between flooding domain boundaries and aggregating reachability information?

Hiding information.

But how does hiding information create failure domain boundaries?

failure-domain

If Router B is aggregating 2001:db8:0:1::/64 and 2001:db8:0:2::/64 to 2001:db8::/61, then changes in the more specific routes will be hidden from Router A. This hiding of information means a failure of one of these two more specific routes does not cause Router A to recalculate what it knows about reachability in the network. Hence a Continue reading

Salesforce brings cross-channel service a step closer with new ‘Snap-ins’

You can't always bring customers to your best customer-service tools, but now you can bring those tools to them thanks to a new addition announced Wednesday for Salesforce's Service Cloud.Dubbed Service Cloud Lightning Snap-ins, the new offering allows organizations of any size to take key support features from Salesforce's Service Cloud and "drop" them into their websites or mobile apps. Case-management and live-chat capabilities can now be added to mobile and Web apps, for example, and a tap-to-call feature is available for Android and iOS.A new module enabling two-way video chat, meanwhile, allows customers and agents to see each other. A customer could also use a smartphone's front-facing camera to show the agent the problem at hand.To read this article in full or to leave a comment, please click here

IDG Contributor Network: How to use Anycast to provide high availability to a RADIUS server

After months of issues, they have finally restored my access to my blog! After such a hiatus, it is my pleasure to bring this particular post. I'm certain many will find it at the very least cool in an "I'm a network geek" kind of a way, or even better: you will find it very educational and even leverage it in your own world.  This is a solution I have been wanting to write about for a long time now, and let's be clear—it is not mine. This entire post is owed to a long-time personal friend of mine who is also one of the most talented and gifted technologists roaming the earth today. His name is Epaminondas Peter Karelis, CCIE #8068 (Pete). Pete designed this particular high-availability solution for a small ISE deployment that had two data centers, as is crudely illustrated by me in the below figure. To read this article in full or to leave a comment, please click here

IDG Contributor Network: Is Salesforce planning a post-Oracle future?

Salesforce and Oracle have an interesting relationship. Even more interesting is the relationship between the companies' two founders, Marc Benioff and Larry Ellison, respectively.Benioff is, after all, a former Oracle alum and a protege of Ellison. And the two have an interesting history—sharing many perspectives (not to mention a penchant for kicking back in their respective Hawaiian bolt-holes). Indeed, the on-again, off-again war of words between the two has been excellent fodder for the peanut gallery. Who will forget the time Benioff's invitation to speak at Oracle Open World was removed?To read this article in full or to leave a comment, please click here

US government agencies are still using Windows 3.1, floppy disks and 1970s computers

Some U.S. government agencies are using IT systems running Windows 3.1, the decades-old COBOL and Fortran programming languages, or computers from the 1970s.A backup nuclear control messaging system at the U.S. Department of Defense runs on an IBM Series 1 computer, first introduced in 1976, and uses eight-inch floppy disks, while the Internal Revenue Service's master file of taxpayer data is written in assembly language code that's more than five decades old, according to a new report from the Government Accountability Office.Some agencies are still running Windows 3.1, first released in 1992, as well as the newer but unsupported Windows XP, Representative Jason Chaffetz, a Utah Republican, noted during a Wednesday hearing on outdated government IT systems.To read this article in full or to leave a comment, please click here

Brocade Workflow Composer enables IT to move with digital speed

In several of my previous posts, I’ve connected the dots between digital transformation and the need for IT to evolve. IT professionals need new technologies, tools and processes to meet the demands of the digital era. This often requires a willingness to do things that were never the norm in previous technology eras.One of the biggest changes that IT must accept is the willingness to automate processes. Whenever I have spoken to IT professionals in the past, particularly network engineers, the reaction to automation tools has been somewhat tepid. As a former network engineer, I can relate. I want to control everything so that I know things are done correctly and everything is operating as it should.To read this article in full or to leave a comment, please click here
