Announcing the Open Source Storage Summit

EMC {Code} to produce events dedicated to topics in open source storage, from storage controllers and platforms to hyperconverged and persistent storage for cloud native apps.

This week at the LinuxCon Japan event, EMC{Code} will launch the first of three Open Source Storage Summits in collaboration with the Linux Foundation. The Open Source Storage Summit is a one-day event co-located at each LinuxCon this year (Japan, North America and Europe) with the first one in Japan on Friday, July 15.

In the broad spectrum of the enterprise technology industry, storage has been one area that has long resisted open source innovation. Some have speculated this is due to the role of risk mitigation in enterprise storage. However, with the rise of cloud native technologies and public cloud infrastructures, the storage industry has seen the first wave of open source innovation, leading to great change in the open source storage management and platform fronts.

The Open Source Storage Summit is an attempt to give attendees a view into all the open source change happening right now in the storage industry. We will feature speakers and topics from a variety of open source communities related to storage, including EMC {code}’s own REX-Ray and CoprHD projects, as well as Ceph, OpenStack, and several others.

Whether you’re interested in speaking or attending, join us at the Open Source Storage Summit, and let’s collaborate on open source storage. If you want to plan your own Open Source Storage Summit or Meetup, let us know in the comments or tweet us @emccode or @johnmark.

Current Open Source Storage Summit schedule (registration via respective Linux Foundation event pages):

Friday, July 15, LinuxCon Japan (Tokyo)

Thursday, August 25, LinuxCon North America (Toronto)

Friday, October 7, LinuxCon Europe (Berlin)

DigitalOcean Launches Block Storage Service for Storage-Hungry Cloud Users

July 14, 2016

Responding from strong customer demand, DigitalOcean is expanding its range of cloud infrastructure services by adding a new block storage offering. The service will use solid state drives (SSD), and will cost $0.10/GB per month, with no additional costs for data ingest or egress. The block storage will be accessible through DigitalOcean droplets, the OS-based virtual machines that are the company’s core offering. Each SSD volume can hold between 1GB and 16TB.

DigitalOcean “originally started with individual developers building websites and simple solutions,” said Julia Austin, who recently joined DigitalOcean as chief technology officer, explaining the new offering. “What we are now seeing from our customer base is more sophisticated use of the productSaaS applications, full applications, with their own customer bases. We’re addressing that, trying to provide everything they need to run their businesses.”

Initially, DigitalOcean’s new York and San Francisco regions will offer the service, with Frankfurt to follow shortly.

The Z File System (ZFS) was originally designed at Sun Microsystem. It is an advanced file system and logical volume manager. It works on Solaris, FreeBSD, Linux and many other operating systems. The features of ZFS include protection against data corruption, compression, volume management, snapshots, data integrity, Software RAID, cache and much more. This tutorial explains how to install the Z File System (ZFS) on Ubuntu Linux 16.04 LTS server and create RAID-1 (mirror).

Best Linux Distros for Small Businesses

GNU Linux started as one man’s personal project – it’s now one of the most popular operating system bases in the world. But unlike macOS and Windows, there’s not just one Linux OS. There are hundreds of individual platforms assembled from components and built upon the Linux kernel. Different distributions (distros) can vary wildly from one another.

So what’s the best choice for your small business? We’ve approached this selection with a few criteria in mind. Stability is first and foremost, because if you’re putting a distro to work, uptime is critical, and solid support provision comes a close second.

We’ve also considered practical capabilities, which is why you’ll find a couple of non-desktop distributions on our list: Linux is perhaps better suited to managing your behind-the-scenes hardware than it is being put in front of users who may be unfamiliar with Gnome or KDE.

UNH-IOL Tackles SDN Interoperability with New Consortium

The University of New Hampshire’s Interoperability Laboratory (UNH-IOL) has launched a software-defined networking (SDN) consortium to provide controller and switch interoperability testing for SDN vendors and service providers. It also will handle conformance and benchmark testing.

The nonprofit says that the SDN Consortium is a natural progression for it, because it is already conducting a lot of other interoperability tests and has much of the needed infrastructure. “We have a very large switch test bed,” says Timothy Winters, UNH-IOL senior executive of software and IP network. “We have a lot of switches because we are already testing, routing, and hosting.” The lab officially opens Aug. 1.

The new tool brings together Chef’s apps into one single interface product to speed up software automation.

Already known as a vendor of software automation tools, Chef software has launched a new tool that combines Chef’s existing software into one, single-interface product. Aimed at software development teams the app combines Chef Delivery and Chef Compliance into one tool. According to the company the aim is to speed up the software delivery process.

Chef Automate includes a new Visibility feature that offers analytics of all the resources managed by Chef through a single interface, the company says, and should help organisations, “safely deploy infrastructure and applications at high velocity and scale”.

From DevOps to BizDevOps: It’s All About the People

Several of us from the OpenCredo team were in attendance at the inaugural EU edition of the DevOps Enterprise Summit conference. We have been big fans of the two previous US versions, and have watched the video recordings of talks (2014, 2015) with keen interest as many of our DevOps transformation clients are very much operating in the ‘enterprise’ space. It was great to be able to attend this London-based conference in person, as although the presentations will soon be on YouTube, by not attending you miss out on the face-to-face interactions and networking.

I’ve attempted to capture some of the key memes we saw over the two days, and if you have any questions then please do get in touch!

It’s all about the people

Several great talks, including Darren Hague’s SAP transformation journey, argued that DevOps is all about the people. For anyone implementing change within a large organisation this should be self-evident. However, as John Willis pointed out, some organisations still don’t get it. John argued that high performing organisations care for their people like strategic assets, and actively work against creating a culture where burnout is tolerated

The Truth About Penetration Testing Vs. Vulnerability Assessments

Organizations Must Put Security Vulnerabilities Into the Context of Their Exploitability

Vulnerability assessments are often confused with penetration tests. In fact, the two terms are often used interchangeably, but they are worlds apart. To strengthen an organization’s cyber risk posture, it is essential to not only test for vulnerabilities, but also assess whether vulnerabilities are actually exploitable and what risks they represent. To increase an organization’s resilience against cyber-attacks, it is essential to understand the inter-relationships between vulnerability assessment, penetration test, and a cyber risk analysis.
