Liveblog: Deploying Containerized OpenStack: Challenges & Tools Comparison

This is a liveblog for an OpenStack Summit session on containerized OpenStack and a comparison of the tools used for containerized OpenStack. The speaker is Jaivish Kothari, from NEC Technologies. Two other speakers were listed on the title slide, but were apparently unable to make it to the Summit to present.

Kothari provides a brief overview of the session, then jumps into a discussion of deployment tools. As illustrated by one of his slides, there’s a huge collection of tools that are used to deploy OpenStack; some are “pure” deployment tools, others are configuration management tools. In this presentation, Kothari says he will focus specifically on OpenStack deployment tools, like Juju (Canonical), Fuel (Mirantis), Crowbar (Dell), and PackStack/TripleO (Red Hat), but I’m not sure how this relates to containerized OpenStack (per the session title).

According to Kothari, some of the challenges in “traditional” (non-containerized) deployment tools are best understood by looking at the challenges in deploying OpenStack:

  • Difficulty related to deployment (conflicts due to services configuration, deployment still prone to failures)
  • Ongoing lifecycle management of OpenStack components

This whole first section of the presentation was setting up the argument that containerizing your OpenStack control plane will help address these challenges. Continue reading

Liveblog: Kuryr Project Update

This is a liveblog of an OpenStack Summit session providing an update on the Kuryr project. The speakers are Antoni Segura Puimedon and Irena Berezovsky. Kuryr, if you recall, was a project aimed at making OpenStack Neutron functionality available to Docker containers; it has since expanded to also offer Cinder and Manila storage to Docker containers, and has added support for both Docker Swarm and Kubernetes as well.

According to Puimedon, the latest release of Kuryr has a diverse base of contributors, with over 45 active contributors.

So, what will be in the Pike release? For the Kubernetes-specific support:

  • This will be the first release
  • Support for Kubernetes Services (this leverages LBaaS v2)
  • Client- and server-side SSL support
  • RDO packaging

What’s planned for Pike, but may not actually make it? (Again, this is for Kubernetes support.)

  • Token support
  • Resource pools
  • Improved support for Services defined as LoadBalancer type

On the Docker side, the following new features and enhancements will arrive in Pike:

  • Support for Swarm mode
  • IPv4 and IPv6 networking
  • TLS support between Docker and the libnetwork plugin

On the Fuxi side, Kuryr is adding support for Manila shares.

At this point, Berezovsky takes over to discuss the release Continue reading

Getting a jump on private LTE networks

Vendor partnerships usually don't raise too many eyebrows or pulse rates around here, but when I came across an announcement by Lemko and Federated Wireless promoting a joint effort on the Citizens Broadband Radio Service (CBRS) it did get my attention.CBRS, if you aren't familiar, refers to shared 3.5 GHz spectrum recently opened by the FCC for commercial applications, and everyone from the big carriers to the likes of Cisco and Google are throwing their weight behind it. One possible application would be LTE services, which could come in the form of extended carrier networks, new cable service provider networks, and even private enterprise networks for IoT or other connectivity.To read this article in full or to leave a comment, please click here

FCC hit with DDoS attacks after John Oliver takes on net neutrality

The U.S. Federal Communications Commission's website slowed to a crawl after comic and political commentator John Oliver urged viewers to flood the agency with comments in support of net neutrality, in what appeared to be a repeat of a 2014 incident.With the FCC headed toward a repeal of net neutrality rules it passed in early 2015, Oliver on Sunday echoed his "Last Week Tonight" commentary on the topic from three years ago. (Note to viewers: The link to Oliver's new diatribe is not safe for work.) As in 2014, the FCC's website seemed to buckle under the load late Sunday and early Monday, but the cause may have been more sinister than a flood of people expressing their support for net neutrality rules.To read this article in full or to leave a comment, please click here

Dell takes Intel’s cue on PCs, puts enterprise on top of the agenda

For the umpteenth time, Dell Technologies has reiterated that PCs are important to the company, and it won't quit the market.But PCs occupied only a few minutes of CEO Michael Dell's opening keynote at Dell EMC World in Las Vegas on Monday. PCs are the engine that keep enterprises chugging, he said.Instead, Dell spent time educating attendees about the new Dell Technologies and its products. It's been less than a year since the US$67 billion Dell-EMC merger was finalized, and a lot of focus was on answering burning questions about the company's future.Dell did say the company would offer the PC-as-a-service worldwide by the end of the year, with more details about the program to be shared on Tuesday. HP and Microsoft are offering PC-as-a-service options, allowing customers to buy devices and support and pay on a monthly basis. That option reduces the hardware acquisition and support costs for companies.To read this article in full or to leave a comment, please click here

African Regional Internet & Development Dialogue Tackles the World of Education

Dates 8-9 May, Kigali, Rwanda

The first ever African Regional Internet Development Dialogue (RIDD) was launched in Rwanda, Kigali on the 8 of May 2017, placing SDG 4 on Education at the center of the conversation of the first day of the meeting. Delegates had an opportunity to explore how the Internet can provide quick wins for education, but most importantly come up with real solutions that can be implemented immediately.

For Africa a skilled workforce that utilizes ICTs effectively is a key factor in determining its competitiveness in the global digital economy and fully exploiting its potential for sustainable growth. It is the basis for social and economic development, and the foundation of an Internet for everyone.

Worth Reading: Be careful what you wish for

After a few minutes of hyperventilating into an empty Dunkin Donuts bag, though, I calmed down enough to appreciate that the guy is trying to provide exactly what I’ve been complaining about the lack of for quite some time now: some kind of logical progression, a path to follow to go from Point BootCamp to Point GotAJob. It’s a helpful roadmap that lays clearly lays out the (many, oh so many) technologies we should be aware of as we work toward professional web dev status. —The New Stack

Dell EMC’s newest switches will come with its open network OS

Dell's drive into open networking accelerated on Monday with the announcement of the first switches to ship with OS10, the company's network operating system that's based on open source.At Dell EMC World in Las Vegas, the company introduced two data-center switches running OS10 Enterprise Edition, an enhanced version of the open-source OS that Dell announced early last year.The software is based on technologies from the Linux Foundation and the Open Compute Project and is already available through an extended beta to customers who already have hardware. The Enterprise Edition is a complete software platform, including Dell's networking stack, but its open-source foundation means it can be extended with third-party software, said Jeff Baher, Dell EMC's executive director, networking.To read this article in full or to leave a comment, please click here

Merged Dell EMC busts out Isilon, XtremIO, and VMax updates

Dell EMC is making one of its broadest rollouts of updated storage gear in years at Dell EMC World on Monday, packing more capacity and performance into several product lines.Coming several months after the completion of the Dell-EMC merger, the update includes the second generation of EMC's XtremIO all-flash array, a new architecture for its Isilon network-attached storage platform, and an improved flash module for the VMax line.Some of the gains made in these products flow from improvements that come like clockwork from other players in the industry. SSDs keep getting bigger, with up to 15.4TB units now available in some of this gear, and Intel CPUs advance with new and faster chipsets, including Haswell (in Isilon) and Broadwell (in VMax).To read this article in full or to leave a comment, please click here

Oracle’s next big business is selling your info

There’s a decent chance you're part of Oracle’s next big business. Not selling products to you, but selling you as a product. That's the idea behind the Oracle Data Cloud, a massive pool of information about consumers and companies.The tech titan has put it together by tracking people across the web and buying data from a variety of sources. People who have their data included may not even know that they’ve opted in for that data collection.There’s no big red button that someone has to click in order to be a part of the company's data collection machine. Instead, its base of user data is fed by a network of third parties. The Data Cloud is primarily fed by three types of sources: publishers, like Forbes and Edmunds, retail loyalty programs, and traditional data brokers like Experian and IHS.To read this article in full or to leave a comment, please click here
