AWS re:Invent re:cap

rePlay

What a week. Some tech conferences I like, and others I love. Falling solidly in my "love" category, the Amazon team pulled off another great event with re:Invent 2015. Of course, the AWS product folks didn’t disappoint, either. (And neither did surprise re:Play party guest Zedd.)

We welcomed many hundreds of visitors to our booth during the three days. Over 200 shirts, many more Ansibulls, and every single sticker, luggage tag, and business card were gobbled up by excited Ansible users and Tower customers.

Perhaps the most entertaining part was to learn what people had to say:

“We heart Ansible.”
“Ansible is the only predictable thing about our environment.”
“DevOps? More like AnsibleOps.”
“You guys changed our lives.”
“I keep getting told I need to look at Ansible.”
“Thank you… just thank you.” (My personal favorite)

Certainly all bold statements for an IT orchestration tool. Even Network World joined in on the fun by naming Ansible one of the hottest products at re:Invent, thanks in part to our new IAM modules that simplify the setup and maintenance of IAM users, groups, keys, and policies.

The sentiments got me thinking. Seemingly, AWS is Continue reading

Making the Case for Building Scalable Stateful Services in the Modern Era

For a long time now stateless services have been the royal road to scalability. Nearly every treatise on scalability declares statelessness as the best practices approved method for building scalable systems. A stateless architecture is easy to scale horizontally and only requires simple round-robin load balancing.

What’s not to love? Perhaps the increased latency from the roundtrips to the database. Or maybe the complexity of the caching layer required to hide database latency problems. Or even the troublesome consistency issues.

But what of stateful services? Isn’t preserving identity by shipping functions to data instead of shipping data to functions a better approach? It often is, but we don’t hear much about how to build stateful services. In fact, do a search and there’s very little in the way of a systematic approach to building stateful services. Wikipedia doesn’t even have an entry for stateful service.

Caitie McCaffrey, Tech Lead for Observability at Twitter, is fixing all that with a refreshing talk she gave at the Strange Loop conference on Building Scalable Stateful Services (slides).

Refreshing because I’ve never quite heard of building stateful services in the way Caitie talks about building them. You’ll recognize most of the Continue reading

What Dell buying EMC means for VMware

With Dell acquiring EMC for a record $67 billion, it raises the question: What does this all mean for VMware and its customers?Officially, Dell says VMware will remain an independent publicly traded company. The wrinkle is that EMC owns 83% of VMware’s stock; and Dell is acquiring EMC.Forrester analyst Glenn O’Donnell says he expects the impact of the merger on VMware customers to be minimal. “You can basically look at this as some musical chairs at the high end,” he says. But other analysts say there could be significant opportunities for Dell to combine its hardware with VMware’s software.+MORE AT NETWORK WORLD: Dell acquires EMC for $67 billion | VMware CEO hits on network virtualization reality, feuding with Cisco & the EMC Federation's future +To read this article in full or to leave a comment, please click here

Worth Reading: Hybrid Infrastructure

Although industry experts anticipate a 44 percent annual growth in cloud-based workloads over the next several years, the reality is that despite rapid cloud adoption, many businesses will continue to have a significant part of their daily operations tied to physical infrastructure and its processes for many years to come. The Cloud is for everyone, but not for everything. — via the data center journal

Google’s OnHub turns out to be part router, part Chromium OS computer

While Google cheerily advertises the 13 antennas packed into its new OnHub router, the company’s been less forthcoming about the software under the hood. Now that some hackers have rooted the high-tech Wi-Fi router, we have some clarity: OnHub appears to run a heavily-modified version of Chromium OS, the same browser-based software that powers Chromebook laptops and Chromebox desktops. The root method for OnHub first appeared on Exploitee.rs. It turns out that the router’s underside contains a hidden switch underneath one of its screws. This switch can boot OnHub into developer mode if you enter a specific keystroke, using a keyboard plugged into the router’s USB port. That keystroke is Ctrl + D, which is precisely what you’d use to enter developer mode in Chromium OS.To read this article in full or to leave a comment, please click here

Why Verizon’s ‘zombie cookies’ are scarier than ever

Like the Walking Dead lurching across your TV screen, Verizon's "zombie cookies" never give up. These hard-to-kill bits of code that track your mobile surfing habits are about to be shared with Verizon's newest acquisition, AOL, and that means additional advertisers will learn even more about you.Beginning in November, if you access the Web via Verizon’'s network, data on "your gender, age range and interests," (according to a Verizon FAQ page on its Relevant Mobile Advertising program) will be pushed to AOL's extensive network of advertisers.To read this article in full or to leave a comment, please click here

Top 5 security threats from 3rd parties

 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.

From Target to Ashley Madison, we’ve witnessed how interconnections with third-party vendors can turn an elastic environment -- where devices, services and apps are routinely engaging and disengaging -- into a precarious space filled with backdoors for a hacker to infiltrate an enterprise’s network. Here are the top five threats related to working with 3rd parties:

Threat #1 - Shared Credentials. This is one of the most dangerous authentication practices we encounter in large organizations. Imagine a unique service, not used very frequently, requiring some form of credential-based authentication. Over time, the users of this service changes, and for convenience considerations, a single credential is often used. The service is now accessed from multiple locations, different devices and for different purposes. It takes just one clumsy user to fall victim to one {fill in the credential harvesting technique of your choice}, to compromise this service and any following user of that service.

Rule 11 is your friend

It’s common enough in the networking industry — particularly right now — to bemoan the rate of change. In fact, when I worked in the Cisco Technical Assistance Center (TAC), we had a phrase that described how we felt about the amount of information and the rate of change: sipping through the firehose. This phrase has become ubiquitous in the networking world to describe the feeling we all feel of being left out, left behind, and just plain not able to keep up.

It’s not much better today, either. SDNs threaten to overturn the way we build control planes, white boxes threaten to upend the way we view vendor relationships, virtualization threatens to radically alter the way we think about the relationship between services and the network, and cloud computing promises just to make the entire swatch of network engineers redundant. It’s enough to make a reasonable engineer ask some rather hard questions, like whether it’s better to flip burgers or move into management (because the world always needs more managers). Some of this is healthy change, of course — we need to spend more time thinking about why we’re doing what we’re doing, and the competition of the cloud Continue reading

Industry Influencers: Application-aware Networking

Network Insight Blogger and industry guru, Matt Conran, featured Plexxi in his October 6 post Application-aware Networking-Plexxi Networks. He believes, “Mobility and dynamic bandwidth provisioning force us to rethink how we design networks.” We agree.

Conran defines application-aware networking as the idea that application visibility combined with network dynamism will create an environment where the network can react to the changing behavior of application mobility and bandwidth allocation requirements. With that in mind, he took a comprehensive look at what we’ve been doing to “reverse the traditional design process and let the application dictate what kind of network it wants.”

Conran states that, “Networks should be designed around conversions but when you design a network it is usually designed around reachability. A conversational view measures network resources in a different way, such as application SLA and end-to-end performance. The focus is not just uptime. We need a mechanism to describe applications in an abstract way and design the network around conversations. The Plexxi affinity model is about taking a high-level abstraction of what you want to do, let the controller influence the network and take care of the low-level details. Affinity is a policy language that dictates exactly how you want the network to Continue reading

The power of PowerShell: An intro for Windows Server admins

Until recently, a clear delineation existed between Windows system administrators and developers. You’d never catch a system administrator writing a single line of code, and you’d never catch a developer bringing up a server. Neither party dared to cross this line in Windows environments. Nowadays, with the devops movement spreading like wildfire, that line is fading away.To read this article in full or to leave a comment, please click here(Insider Story)

Dancing on the grave of Flash

I’ll be honest. I hate Flash. I loathe Flash. I abhor Flash. And these are educated feelings. Flash is tremendously insecure, has no way of managing updates across a fleet of computers, is needlessly inefficient, chews up battery life, is as proprietary and closed a system as they come in an era where we have rich and stable open Web standards, and in general is a tax on the Web experience. I could not be happier to see Flash go.Opinions vary about exactly when Flash died. A minor but vocal group, consisting largely of Web advertisers, still says it’s alive. (Think again, folks.) Some attribute the final nail in Flash’s coffin to the decision by video giant YouTube in September to stop delivering video content to users of modern browsers with Flash and instead use the cross-platform open standard HTML5. (YouTube had to wait until better buffering technology arrived in the HTML 5 standard so that the provider could switch bit rates for streaming video on demand for less buffering as the traffic shape required.) Others say it’s when Google disabled Flash-based advertising in Chrome and developed a tool that let AdWords, its advertising platform, automatically convert Continue reading
