Salt – The basics

In my last post, I showed you how I automated my Kubernetes lab build out by using Salt.  This took the build time and cut it by more than 70% (Im guessing here but you get the point).  In addition, I’ve been making all of my changes for the cluster in Salt rather than applying them directly to the host.  Not only does this give me better documentation, it allows me to apply changes across multiple nodes very quickly.  You might be wondering why I chose Salt since I’ve blogged about Chef in the past.  The answer isn’t cut and dry, but Salt just made sense to me.  On top of that, there is VERY good documentation out there about all of the state and state functions so it’s pretty easily consumable.    As I walk through the process I used to create the lab build scripts, I hope you’ll start to catch onto some of the reasons that made me decide to learn Salt.

Let’s start by taking a look at me GitHub repo…

Cheap mobile subscriptions the bait as Euro operators become more aggressive

Consumers seem to be coming out on top as a growing number of European telecom and cable operators offer discounted mobile subscriptions as a bonus for choosing other services.Bundles with broadband, telephony and TV across fixed and mobile networks are becoming increasingly important for operators across the continent. The latest example is British operator BT, which on Wednesday announced its return to the consumer mobile market.The expressed goal is to offer the best-value, 4G SIM-only mobile deals as a reward for its broadband customers. The cheapest plan costs £5 (US$7.40) per month and includes 500MB of data, unlimited texts and 200 voice minutes. BT’s broadband subscribers can also choose a plan with 2GB of data, unlimited texts and 500 voice minutes for £12 per month, the operator said.To read this article in full or to leave a comment, please click here

Nigeria joins list of African countries threatening prison sentences for mobile operators

Nigeria, Africa’s largest telecom market, has joined the list of countries on the continent that will impose prison sentences on officials at mobile operators that continually fail to deliver quality services to customers.Tanzania and Zambia are among African countries imposing prison sentences on mobile operators who do not provide quality telecom services.The Nigeria Consumer Protection Council (CPC) has warned mobile phone operators that it would soon start filing criminal charges against them as a way of whipping them to order. The consumer watchdog, supervised by the Nigerian government under the Federal Ministry of Trade and Investment, said lack of strict punishment for erring companies had led to a situation where consumers no longer get value for their money in the West African country.To read this article in full or to leave a comment, please click here

Hands on: AT&T Velocity hits the WiFi hotspot

AT&T Velocity I’m using the ZTE-built AT&T Velocity WiFi hotspot as I write up my quickie review of the device here, and sure enough it’s providing me with ample speed as I fact check on the web during this process. The basic purpose for the device is to provide you with 2.4- or 5-GHz WiFi Internet access – via an AT&T 4G LTE connection -- when you can’t find free or safe WiFi in the wild. You just need to make sure you’re not somewhere that blocks usage of such devices – a practice frowned upon by the FCC.To read this article in full or to leave a comment, please click here

US lawmakers push for auctions of gov’t spectrum

A group of U.S. lawmakers has reintroduced legislation aimed at encouraging government agencies to give up their spectrum by allowing the agencies to share in the profits when the spectrum is auctioned to commercial mobile carriers.The Federal Spectrum Incentive Act, introduced in both the Senate and the House of Representatives Thursday, mirrors legislation that was introduced in the House in 2013 but failed to pass. But the need for the bill is growing, sponsors argue, because of the skyrocketing consumer demand for commercial mobile and unlicensed WiFi spectrum.To read this article in full or to leave a comment, please click here

Tech companies call on US to end bulk collection of metadata

A slew of tech companies have joined privacy groups in calling for the U.S. government to reform its surveillance practices.An open letter from the tech industry and privacy organizations urges the government to not renew the provision in the Patriot Act that allows for the bulk collection of metadata. That provision, called Section 215, expires in June.“There must be a clear, strong, and effective end to bulk collection practices,” reads the letter, which was signed by the industry group Reform Government Surveillance, whose members include including Apple, Facebook, Google, Evernote, Twitter and Microsoft. Any data collection efforts need to protect user rights and privacy, the letter said.To read this article in full or to leave a comment, please click here

Gold Apple Watch buyers will receive special treatment

When the upcoming Apple Watch goes on sale on April 24, it will be the most complex and downright confusing product Apple has ever released, by far. With an assortment of styles, bands, and materials, there will be a seemingly never-ending selection of options for users to choose from.At the same time, the Apple Watch will be the most expensive product Apple has ever released. While the Sport models will start at just $349 (for the 38mm version), the Edition models will start at $10,000 and range all the way up to $17,000. Naturally, not every Apple Store will carry the expensive gold Edition models. During Apple's most recent Apple Watch event, Tim Cook noted that only select stores will carry the device, and in limited quantities at that. What's more, it's been reported that the Edition Apple Watch models will be safely stowed away in secure safes in-store, much in the same way that boutique watch stores protect their most valued merchandise.To read this article in full or to leave a comment, please click here

Uber’s Amsterdam office raided by Dutch authorities

Uber keeps crashing into laws and regulations in Europe, but it’s keeping the foot on the accelerator.Following raids in Belgium and France, Dutch authorities raided Uber’s Amsterdam office on Thursday as part of an investigation into the ride-hailing service UberPop, which a court ruled illegal in the Netherlands.The raid’s main goal is to obtain records that show the size of the UberPop operation, a spokeswoman for the DutchHuman Environment and Transport Inspectorate said, adding that the authority, for instance, wants to find out the number of UberPop drivers. The raid is still ongoing and is being conducted by the inspectorate in cooperation with the police.To read this article in full or to leave a comment, please click here

Cisco patches autonomic networking flaws in IOS routers and switches

Cisco Systems released firmware updates for several routers and switches that run its IOS and IOS XE software in order to fix flaws in their autonomic networking infrastructure (ANI) feature.ANI is an automatic device management feature that allows Cisco IOS devices to securely join a domain and be configured without prestaging—setting up the necessary accounts in advance.Cisco’s new patches, released Wednesday, address three vulnerabilities in the way Cisco IOS and IOS XE devices handle autonomic networking (AN) messages.One vulnerability could allow a remote unauthenticated attacker to force a vulnerable device to join a rogue autonomic domain by sending it specially crafted AN messages. This would give the attacker limited control over the device and would prevent it from joining the legitimate domain, Cisco said in a security advisory.To read this article in full or to leave a comment, please click here

Will embedded OS and middleware help save Blackberry?

The financial news for Blackberry is potentially bad this week, as it has been for most of the past few years. Some analysts are predicting that the Canadian company will post losses of as much as 7 cents per share, though the consensus seems to be closer to 3 cents. If that happens, it’ll be Blackberry’s fourth quarter out of the last five to show a decline. Blackberry, as most know, has been suffering through an ongoing and painful fall from grace for quite a while now. In part, that’s because it’s had an awfully long way to fall – at its apex, Research in Motion was one of the most important technology companies on the planet, taking the business world by storm with its Blackberry handsets and doing at least as much as Apple – which gets the lion’s share of the credit these days – to popularize the idea of a phone that did much more than make calls and send texts.To read this article in full or to leave a comment, please click here

IoT could help give your local area its own power grid

The Internet of Things is mostly about achieving greater scale, but in the case of an upcoming demonstration project, it will show how electrical grids can work at a smaller scale.The testbed announced Thursday by the Industrial Internet Consortium (IIC) will bring together software and other components for microgrids, which link together local, alternative sources of power and energy storage. Those sources, including rooftop solar panels and wind turbines, can keep providing power even if the main grid goes down.Most power grids were built for producing energy in one place and distributing it to users over a wide area. They’re not all equipped to manage or take advantage of small power sources out at the edge of the grid. The IIC, which is trying to get big industries and tech vendors on the same page about the Internet of Things, formed the testbed to promote work on IoT components for microgrids.To read this article in full or to leave a comment, please click here

What excites you about network virtualization?

Virtualization is actually nothing new to me, to be honest, because I’ve been dealing with multi-tenancy, which really in my mind, started on the WAN side where VPNs were really one of the first early versions of introducing multi-tenancy and segmentation of the network, and leveraging virtualization-type technology on hardware. It’s just fascinating to see how much that’s evolved and taken off in the compute world. Now, we’re coming back together full circle with SDN. The network is now playing catch-up with how much agility and flexibility virtualization has provided to the compute world. I believe I have been doing virtual networking for a number of years now, but obviously it’s morphed into something much more powerful Continue reading
