IDG Contributor Network: Using a hybrid cloud file system to meet your storage needs

An increasing number of businesses are moving their data to the cloud to take advantage of the cost, scalability and efficiency benefits associated with not having to procure or maintain significant amounts of hardware. And indeed, cloud data storage can certainly help organizations achieve superior ROI; however, oftentimes when choosing a cloud-only file system such as Box or Dropbox, these organizations encounter significant problems – some of which can actually outweigh the benefits. These problems include: Due to inherent limitations in cloud protocols, accessing files from the cloud is rife with latency. This is particularly prevalent when accessing large files or simultaneously accessing a large number of files. Active directory access permission control. The permission schemes for cloud-based file systems are often different than your on-premises environment, causing Active Directory permissions to become an issue for both user and administrator levels. User interface. Losing the familiar file server interface, especially the mapped letter drive interface for a network share, forces users to learn and entirely new user interface. In addition to the increased stress, it can also reduce user efficiency in the short term. Shadow IT. Since the files are no longer located within the company’s infrastructure, IT Managers lose Continue reading

DockerCon Updates on Containerd, BuildKit, and a Reflection about the Enduring Value of Docker Engine

Two weeks ago was our eighth DockerCon in just four years. Our community of contributors, developers, IT users, enterprises and ecosystem partners has grown exponentially into the millions,  anchored on our founder Solomon Hykes’ simple premise of democratizing the use of the software container. Today as was from the beginning, Docker creates simple tooling and a universal packaging approach that bundles up all application dependencies inside the container.  Docker Engine enables applications to run anywhere consistently on any infrastructure, solving “dependency hell” for developers and operations teams, and eliminating the “it works on my laptop!” problem.

In the past 2 years, Docker Engine’s codebase has been refactored into several reusable components, the most important being containerd, the core container runtime, and BuildKit, the part of Docker Engine used to build images. In the contribute and collaborate track at DockerCon, Michael Crosby and Tonis Tiigli gave an update on these two projects (video, slides)

Is implementing and managing Linux applications becoming a snap?

Quick to install, safe to run, easy to update, and dramatically easier to maintain and support, snaps represent a big step forward in Linux software development and distribution. Starting with Ubuntu and now available for Arch Linux, Debian, Fedora, Gentoo Linux and openSUSE, snaps offer a number of significant advantages over traditional application packaging. Compared to traditional packages, snaps are: easier for developers to build faster to install automatically updated autonomous isolated from other apps more secure non-disruptive (they don't interfere with other applications) So what are snaps? Snaps were originally designed and built by Canonical for use on Ubuntu. The service might be referred to as “snappy”, the technology “snapcraft”, the daemon “snapd” and the packages “snaps”, but they all refer to a new way that Linux apps are prepared and installed. Does the name “snap” imply some simplification of the development and installation process? You bet it does!To read this article in full, please click here

The Lustre HPC file system has another new home — and it’s the right one

After years of bouncing from one company to another, the Lustre file system that is so popular in high-performance computing (HPC) has been sold yet again. This time it went to an enterprise storage vendor. Finally, it’s in the hands of a company that makes sense.DataDirect Networks (DDN) announced it purchased the Lustre File System from Intel this week as Intel looks to pare down non-essential products. DDN got all assets and the Lustre development team, who are undoubtedly relieved. The announcement was made at the International Supercomputing Conference (ISC) in Frankfurt, Germany.[ Check out AI boosts data-center availability, efficiency.

List of EVPN and DC-related IETF drafts (as of 1H 2018)

Ethernet Virtual Private Network (EVPN) solution is becoming pervasive for Network Virtualization Overlay (NVO) services in data center (DC) networks and as the next generation VPN services in service provider (SP) networks. As a result of this popularity a lot of work is going on in IETF in this area. In this post I collect links to some of the interesting IETF drafts in this area.
All this information is relevant for 1H 2018 timeframe. Keep in mind to pay attention to which version of draft you’re reading – this drafts are frequently updated.

Service Chaining using Virtual Networks with BGP VPNs

This document describes how service function chains (SFC) can be applied to traffic flows using routing in a virtual (overlay) network to steer traffic between service nodes. Chains can include services running in routers, on physical appliances or in virtual machines. Two techniques are described: in one the service chain is implemented as a sequence of distinct VPNs between sets of service nodes that apply each service function; in the other, the routes within a VPN are modified through the use of special route targets and modified next-hop resolution to achieve the desired result.

Want affordable SDN products? Check the secondary market

Frankly (no pun intended), I have to admit that I’m growing increasingly frustrated with certain trends in networking.For example, it’s not that I don’t like the dream or idea of software-defined networking (SDN) — it’s not that I don’t think it’s superior to the older way of setting up or monitoring a network. It’s just that I’m becoming increasingly concerned that small- to medium-size enterprises (SMEs) won’t be able to keep up. And the media that follows this trend isn’t really brining to light the extreme cost of some of these systems.Pricewise, many of the product lines are intended for large networks. There's no way that a smaller company could even begin to afford them. For example, one trainer told me that a certain SDN product was scaled to start at 500 site deployments!!To read this article in full, please click here

MTU and TCP MSS

The largest chunk of bytes that a transport protocol can forward across specific medium is called MTU – Maximum Transmission Unit. If we speak about Ethernet, which is today the most common, he has by default 1522 bytes MTU. The story about MTU is that the MTU of specific protocol basically defines how much payload (or highest protocols headers + their payload) it can carry in its biggest packet, not counting his own headers. Putting more payload into single packet than the MTU allows will result in fragmentation, the process of slicing the frame into more smaller frames so that

Debugging data flows in reactive programs

Debugging data flows in reactive programs Banken et al., ICSE’18

To round off our look at papers from ICSE, here’s a really interesting look at the challenges of debugging reactive applications (with a certain Erik Meijer credited among the authors).

… in recent years the use of Reactive Programming (RP) has exploded. Languages such as Elm and libraries such as Reactor, Akka, and Rx are being used by companies such as Netflix, Microsoft, and Google, to build highly responsive and scalable systems.

The rise of reactive programming fits well with the increasing need to process streams of data. In a reactive program, you set up a data processing pipeline and then wait for input to arrive.

Many RP implementations share a notion of a collection that abstracts over time, in contrast to space like standard collections. This collection comes in different flavors, such as Observable (Rx)… the implementations differ in the precise semantics of their collections, their execution model (push/pull) , and the set of available operators.

While in theory events and threads are duals, in practice the RP abstraction works very well for expressing streaming pipelines. If you have an abstraction over time though, Continue reading

OpenStack Summit Vancouver recap: What we did and what’s next

A few weeks ago, I set out to the beautiful city of Vancouver’s convention center, along with a boatload of rocket turtles and a stellar team. It was a great time with a wonderful scenic view of the ocean. I’ve been at Cumulus a few months now, but I can’t help but enjoy looking around, seeing the friends I’ve made in the industry, and the friends and companies Cumulus has worked with over the years. It is exciting to have thousands of people coming together at OpenStack Summit Vancouver to work on a shared goal.

This year, we were lucky enough to have our very own Pete Lumbis take the stage with David Iles of Mellanox to present our joint solution around the latest SDN revolution, which is centered on creating efficient virtualized data center networks using VXLAN & EVPN.

In the next few paragraphs, I’ll share some highlights of the event, some photos, and a recap of that exact discussion. There was a lot to learn and discover, and I’m excited to share the details.
