Lenovo jumps into the pay-per-use server market

A year ago, every major vendor had a pay-per-use on-premises server as a way to counteract the popularity of cloud vendors — all but Lenovo.Well, no more. The company is launching TruScale, a pay-per-use system for its servers that it says offers true pay-per-use and no requirement of a minimum capacity purchase. TruScale is a subscription-based offering that allows customers to use and pay for data center hardware and services either on premises or at a customer-preferred location without having to purchase the equipment outright. Capacity can be scaled up or down to accommodate business needs automatically. It requires no minimum capacity purchase, which HPE and Dell do require.To read this article in full, please click here

Do You Want Privacy With That?

You may have heard about CloudPets being pulled off shelves for recording kids’ voices and that data being leaked, or the EU recalling kids’ smart watches for giving away children’s location in real time. If you’re shopping for any sort of Internet-connected device, you should be worried about your privacy and investigating how much data your new gadget is collecting. That’s why we’ve joined Mozilla in calling on big retailers in the US like Target, Walmart, Best Buy, and Amazon to publicly endorse and apply our minimum security and privacy guidelines and stop selling insecure connected devices.

From the letter: “Given the value and trust that consumers place in your company, you have a uniquely important role in addressing this problem and helping to build a more secure, connected future. Consumers can and should be confident that, when they buy a device from you, that device will not compromise their privacy and security. Signing on to these minimum guidelines is the first step to turn the tide, and build trust in this space.”

In total, the letter is co-signed by 11 organizations: Mozilla, Internet Society, Consumers International, ColorOfChange, Open Media & Information Companies Initiative, Common Sense Media, Story of Continue reading

BrandPost: Wi-Fi Next Steps: 802.11ax or 802.11ac?

With a new wireless standard ready and available, 2019 unwraps a wireless conundrum as 802.11ax solutions take their place in the market. You may also hear about Wi-Fi 6, which is just the new nomenclature used by the Wi-Fi Alliance (instead of 802.11ax) in the effort to simplify the naming convention. With a hat tip to iOS, this nomenclature is pretty familiar to mobile users so there’s a good chance we’ll see Wi-Fi 7, 8, and 9 in years to come. For the sake of consistency in our comparison of the two standards discussed here, I will refer to the new standard as 802.11ax.Outside what to call the new standard, Aruba and others have introduced APs that leverage the new performance capabilities of 802.11ax. The new Wi-Fi standard includes some clever engineering that improves performance and saves battery life, but it may not be the right choice, nor the only option, to meet the needs of your midsize organization.To read this article in full, please click here

Future Thinking: Alissa Cooper on the Technical Impact of Internet Consolidation

In 2017, the Internet Society unveiled the 2017 Global Internet Report: Paths to Our Digital Future. The interactive report identifies the drivers affecting tomorrow’s Internet and their impact on Media & Society, Digital Divides, and Personal Rights & Freedoms. While preparing to launch the 2019 Global Internet Report, we interviewed Alissa Cooper to hear her perspective on the forces shaping the Internet’s future.

Alissa Cooper is a Fellow at Cisco Systems. She has been serving as the Chair of the Internet Engineering Task Force (IETF) since 2017. Previously, she served three years as an IETF Applications and Real-Time (ART) area director and three years on the Internet Architecture Board (IAB). She also served as the chair of the IANA Stewardship Coordination Group (ICG). At Cisco, Cooper was responsible for driving privacy and policy strategy within the company’s portfolio of real-time collaboration products before being appointed as IETF Chair. Prior to joining Cisco, Cooper served as the Chief Computer Scientist at the Center for Democracy and Technology, where she was a leading public interest advocate and technologist on issues related to privacy, net neutrality, and technical standards. Cooper holds a PhD from the Oxford Internet Institute and MS and BS Continue reading

ExaBGP – handling route withdrawal

In our last post we talked about how we can programmatically talk and listen to ExaBGP. By the end of the post, our Linux server was listening for BGP updates, processing them, and creating static routes based on the information it learned. We worked through some issues to get that far – but also recognized that we had a ways to go. In this post, we’ll start tackling some of the other issues that are lingering with this implementation. So let’s dive right in and start knocking these out!

The first issues I want to talk about isn’t actually an issue anymore – but it’s worth mentioning since we sort of solved it accidentally. At this point – we’ve only processed BGP update messages that have included a single router advertisement. Said more specifically – BGP update messages that included a single NLRI. A BGP update message can (and will) contain multiple NLRI’s so long as the path attributes are the same for all the prefixes. For folks not familiar with BGP – NLRI (Network layer reachability information) are basically the routes or prefixes that are being sent to us. If we go back and look at the BGP update Continue reading

SD-WAN can help solve challenges of multi-cloud

With SD-WAN becoming remote users’ primary access to cloud-based applications, and with organizations deploying multi-cloud environments to optimize performance, it’s important for IT pros to choose SD-WAN technology that supports secure, low-latency and easy-to-manage connectivity to their cloud providers.To read this article in full, please click here(Insider Story)

Operating Cisco ACI the Right Way

This is a guest blog post by Andrea Dainese, senior network and security architect, and author of UNetLab (now EVE-NG) and  Route Reflector Labs. These days you’ll find him busy automating Cisco ACI deployments.

In this post we’ll focus on a simple question that arises in numerous chats I have with colleagues and customers: how should a network engineer operate Cisco ACI? A lot of them don’t use any sort of network automation and manage their Cisco ACI deployments using the Web Interface. Is that good or evil? As you’ll see we have a definite answer and it’s not “it depends”.
