The many dimensions of cloud value

Do you hear that grating sound of value clash among cloud providers? It’s the sound of attempted differentiation, that reason you buy Starbucks instead of Dunkin Donuts, Peet’s or perhaps Tim Horton’s brew. Brand thinkers want us to choose something we like because they know once we do, we will stay. We’re creatures of habit. We dislike the qualification process of choosing new vendors for coffee, as well as IT gear and services.Much marketing focus is going towards incremental services bundles that make one cloud vendor seem, or actually be, better than the offerings of another. Determine the value of the cloud services you need The first smoke cloud that obscures actual value of cloud services is the dizzying value calculator. This device, when present (and it’s often missing), allows you to plug in what you predict (you can predict, can’t you?) your ongoing costs will be for a particular set of data processing needs.To read this article in full or to leave a comment, please click here

Enter the brave new world of Windows 10 license activation

Windows 10 brought a lot of changes to Microsoft's flagship desktop operating system when it debuted on July 29, 2015, and it has changed even more since then. With the release of the Anniversary Update in August (Build 1607 for Current Branch users, at Build 14393.105 as I write this), even license activation has changed. Here's what most users of the business-oriented Windows 10 Enterprise will see if they check their Activation screen:To read this article in full or to leave a comment, please click here(Insider Story)

Oracle CEO Mark Hurd: We have the whole cloud stack

Few enterprise IT transformations can match the importance of today’s long migration from on-premises, client-server computing to cloud computing. This week at Oracle’s mammoth OpenWorld conference in San Francisco, Oracle will make it abundantly clear that it intends to become a leader in all three flavors of cloud -- not only SaaS, where the company has already demonstrated strength, but also in PaaS and IaaS, where Oracle is a new player.To read this article in full or to leave a comment, please click here(Insider Story)

Reaction: Devops and Dumpster Fires

Networking is often a “best effort” type of configuration. We monkey around with something until it works, then roll it into production and hope it holds. As we keep building more patches on to of patches or try to implement new features that require something to be disabled or bypassed, that creates a house of cards that is only as strong as the first stiff wind. It’s far too easy to cause a network to fall over because of a change in a routing table or a series of bad decisions that aren’t enough to cause chaos unless done together. —Networking Nerd

Precisely.

But what are we to do about it. Tom’s Take is that we need to push back on applications. This, also, I completely agree with. But this only brings us to another problem—how do we make the case that applications need to be rewritten to work on a simpler network? The simple answer is—let’s teach coders how networks really work, so they can figure out how to better code to the environment in which their applications live. Let me be helpful here—I’ve been working on networks since somewhere around 1986, and on computers and electronics since Continue reading

Explaining security automation and its evolving definitions

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.There’s been a lot of talk about security automation, but it’s increasingly unclear what is what. For example, a Network World article on security automation last year focused mostly on threat detection, a Gartner report on Intelligent and Automated Security Controls focused on the threat intelligence component, and another recent piece referenced security automation simply as “the automation of cybersecurity controls.”To read this article in full or to leave a comment, please click here

Oracle is also getting in on the chatbot revolution

Oracle CTO Larry Ellison ordered himself some new business cards on stage at the company's OpenWorld conference in San Francisco on Sunday, just by having a conversation. As part of his keynote address to attendees, Ellison took the time to show off a new set of tools for creating intelligent chatbots that integrate with Oracle's software. It's aimed at making it easier for businesses to build bots that let users connect with their enterprise software, and help businesses connect with consumers. Chatbots are a hot topic in the tech industry, with companies like Facebook, Microsoft and Slack all building tools that companies can use to create intelligent, automated conversation partners. Their growing popularity comes down to a few factors, including the proliferation of smartphones, fast internet connections and messaging apps.To read this article in full or to leave a comment, please click here

Worth Reading: Your comfort zone may destroy the world

Journalism has been on life support since the advent of social media, but this past year we have witnessed the quick, painful death of truth, and it may be gone forever. Put a comfortable lie in an echo chamber, and nobody will challenge it. It will reverberate until it is accepted as actually true. Then, the willfully ignorant will shout it as loudly as they can. It may be their truth, but that does not make it true. —Shelly Palmer

Cisco discloses PIX firewall, IOS software security holes

Cisco has warned of a high priority security hole in its IOS software that could have let attackers snatch memory contents from a variety of products that could lead to the disclosure of confidential information. +More on Network World: Cisco buys into containers with Container X acquisition+ Specifically Cisco said the vulnerability is due to “insufficient condition checks in the part of the code that handles [Internet Key Exchange] IKEv1 security negotiation requests. An attacker could exploit this vulnerability by sending a crafted IKEv1 packet to an affected device configured to accept IKEv1 security negotiation requests.”To read this article in full or to leave a comment, please click here

IDG Contributor Network: Desktop use off 11% in past year. Winner: smartphones

Co-workers peering at their smartphones more than ever isn’t an optical illusion, and you’re not imagining seeing a bunch of shiny bald pates or lustrous weaves of hair where there were once friendly faces. Smartphone use increased more over the past year compared to tablets and PCs.That’s among the tidbits in a new comScore study on application use.Other revelations from the report corroborate why audible alerts from smartphones are less common and it's become unusual to hear the beeps of text messages in some places—such as commuter railway cars: Large numbers of people are rejecting notifications, comScore suggests in research it published this month. “Push notification fatigue” is to blame, it says.To read this article in full or to leave a comment, please click here

Teenager claims to have accessed FTPs, downloaded data from every state with .us domain

A security researcher going by Minxomat scanned IPv4 addresses and then released a list of nearly 800,000 open FTP servers, meaning no authentication is required to access them. His scan revealed that 4.32% of all FTP servers in the IPv4 address space allowed “anonymous” users to login with no password.“This is a list of all (796,578) FTP servers directly connected to port 21 in the IPv4 address space that allow anonymous logins,” Minxomat wrote on GitHub. “The login must be completed in less than five seconds to qualify for this list.”If an FTP server was meant to be public, he did not include it in the list. In his post describing “mass-analyzing a chunk of the internet,” Minxomat said he set up filters to exclude other results such as “POS system firmware update servers and printers (firmware|printer).”To read this article in full or to leave a comment, please click here
