Windows RT

Posted by: Margaret Rouse
“Another thing to keep in mind about Windows RT is that the only way users will be able to install apps on it will be if they download them from the official Windows Store…So that right there means that most of the crapware that IT admins need to clean off isn’t even going to be an issue on Windows RT.”Brian Madden

Today’s WhatIs.com Word of the Day is Windows RT.   It’s a slimmed-down version of Windows 8 for mobile devices with ARM processors (think tablets).  Microsoft hasn’t officially explained what the letters RT stand for.

“While OpenID is all about using a single identity to sign into many sites, OAuth is about giving access to your stuff without sharing your identity at all.”Eran Hammer-Lahav

OAuth (Open Authorization) is an open standard for token-based authentication and authorization on the Internet.

There’s a lot of buzz about how OAuth is making it possible for end users to move from website to website without having to expose passwords — the authentication part — but the really powerful part of OAuth is that its access tokens specify what data can be accessed — the authorization part.

“The proposed law, which passed the House in late April, aims to give the government some oversight into protecting critical infrastructure facilities that are owned by private-sector companies.”Rob Westervelt

Today’s WhatIs.com Word of the Day is Cyber Intelligence Sharing and Protection Act of 2011 (CISPA).

Critics of the legislation argue that a lack of clarity in the bill could lead to massive eavesdropping on private communications.  And by “private,” I mean “corporate.”

Surface tablets

Posted by: Margaret Rouse

“On the hardware front, what does it say about the tablets Microsoft is seeing from its OEM partners…? Either they are not happy with the devices out there, or they are not satisfied with only taking a licence fee from selling Windows-based tablets.”Jan Dawson

Today’s WhatIs.com Word of the Day is Surface, Microsoft’s new line of tablets which will go on sale later this year.

Surface tablets are expected to be priced comparably to Apple and Android products, with the Windows RT version selling for about the same price as its chief competitor, the iPad, and the Windows 8 Pro version selling for the same price as the MacBook Air laptop.

VMware Horizon Application Manager

“The app manager doesn’t just keep track of access to applications, but also licensing, and it knows how to harvest back a license if you are not using it.” Timothy Prickett Morgan

Today’s WhatIs.com Word of the Day is VMware Horizon App Manager. In my humble opinion, app managers are the firewalls of the future.  Firewalls with application portfolio management benefits.

Cloud database

cloud database
“The wrong cloud database strategy can create application performance problems significant enough to discredit a cloud service, forcing the provider to incur additional costs to establish credibility with users.” — Tom Nolle

Today’s WhatIs.com Word of the Day is cloud database. A cloud database is a database that has been optimized or built for a virtualized computing environment.

Open APIs

Posted by: Margaret Rouse
“One of the cardinal rules of open source is reciprocity: you can use my open-source code under the same terms that it was given to me. But as open source shifts to open APIs, “open” is increasingly a one-way street.” Matt Asay

Today’s WhatIs.com Word of the Day is open API.  It’s what makes all your iPhone apps possible.  Developers have a love/hate relationship with them because they make mashups possible (that’s the love part) but the API publisher has all the power in the relationship (that’s the hate part).

Dirty electricity and electrical pollution

Posted by: Margaret Rouse
data center power
“It’s like Tesla versus Edison all over again. Alternating current (AC) is king today, but when it comes to finding ways to improve data center energy efficiency, some industry experts say direct current (DC) deserves a second look.”Alex Barrett

Today’s WhatIs.com Word of the Day is dirty electricity — also known as electrical pollution.

From Power-saving technologies in the data center

Electricity comes from the utility in alternating current (AC). AC is the form in which power is more easily distributed. AC is converted to DC at the power distribution unit, then converted to AC again to push out to the servers, and is converted one more time to DC at each individual server.

In a DC power distribution system, there is only one conversion from the main building AC to DC at common power supply for multiple pieces of equipment. The DC power is fed directly to the servers and switches, and also keeps the batteries charged. This has been the approach in the telco industry for decades on high-end PBX equipment.

DC-powered servers don’t have power supplies built in. The power supply is in the infrastructure. Taking the power supplies out of the equipment itself and putting it in the rack reduces space and takes away the need for an extra conversion.

NoOps – the end of the operations team as we know it today

Posted by: Margaret Rouse
DevOps, NoOps
“The developers used to spend hours a week in meetings with Ops discussing what they needed, figuring out capacity forecasts and writing tickets to request changes for the datacenter. Now they spend seconds doing it themselves in the cloud.” — Adrian Cockcroft

Today’s WhatIs.com Word of the Day is NoOps.  NoOps is one of those buzzwords that gets people’s blood boiling.  It implies the end of the operations team as we know it today.  But be careful, because the key takeaway in that sentence is “as we know it today.”

IT is becoming a utility that we purchase from a third-party provider. And just as you won’t find a generator for electricity and a team to support it on your next visit to Company XYZ, you’re not going to find a fully-staffed operations team there ten years from now.

Event-driven architectures and service-oriented architectures are complements

“In the real world, a service-oriented archtecture (SOA) and an event-driven architecture (EDA) are complements. An EDA allows special handling of application communications that are of vital importance to the enterprise. An SOA extends flexible application communications across the Web.”Wayne Kernochan

Today’s WhatIs.com Word of the Day is event-driven application.
