Virtualization versus Containers: Is there a clear winner? Does it really matter?

Filed under
Server
Misc

Will virtual machines disappear? No. Not anytime soon. This implies that the one day, container technology will eventually replace traditional virtual machines. So, I will save you from reading this entire piece to reach the conclusion of there being a clear winner. The answer is: no. There isn’t a clear winner primarily because both technologies are not one and the same. Each boasts their own respective features and functions and each solve their own set of problems. Understanding the problems in which each solves will better prepare you from misusing the technology.

  • Flavors of Data Protection in Kubernetes

    As containerized applications go through an accelerated pace of adoption, Day 2 services have become a here and now problem.

  • Doing the cloud differently

    Jeff Dike, one of the contributors to Linux, had developed a technology called User-mode Linux. UML, as it was known, allowed developers to create virtual Linux machines within a Linux computer. This Matrix-like technology was groundbreaking and opened the door for the virtualized cloud we know today.

    One of the developers Dike’s technology enabled was a young technologist named Christopher Aker. He saw an opportunity to use this technology not to build the next Salesforce or Amazon, but to make cloud computing less complicated, less expensive, and more accessible to every developer regardless of where they were located, what their financial resources were or who they worked for. The company he built — Linode — helped pioneer modern cloud computing.

  • A day in the life of a quality engineering sysadmin

    Let me begin by saying that I was neither hired nor trained to be a sysadmin. But I was interested in the systems side of things such as virtualization, cloud, and other technologies, even before I started working at Red Hat. I am a Senior Software Engineer in Test (Software Quality Engineering), but Red Hat, being positioned so uniquely because its products are something primarily used by sysadmins (or people with job responsibilities along similar lines) and also most of Red Hat’s products are primarily focused on backend systems-level instead of user application level. Our testing efforts include routine interaction with Red Hat’s Virtualization, OpenStack, Ansible Tower, and Hyperconverged Infrastructure.

    When I was hired, I was purely focused on testing Red Hat CloudForms, which is management software for the aforementioned environments. But as one of our previous senior software engineers departed to take on another role within Red Hat, I saw an opportunity that interested me. I was already helping him and learning sysadmin tasks by then, so after looking at my progress and interest, I was a natural successor for the work in my team’s perspective. And hence, I ended up becoming a sysadmin who is working partly as a software engineer in testing.

  • The Substrate To Bind Datacenter Switching And Routing

    The appliance model, where the hardware and software were tightly controlled by a single vendor, held sway in the datacenter for decades. But that top-to-bottom stack been peeling apart, oddly enough because it was never established on the PC, but particularly as Linux emerged as an open, cross platform operating system that was eager embraced on servers, first by the HPC community and then by the hyperscalers and the cloud builders.

    Even with Unix servers, which were open in terms of supporting common APIs and providing a modicum of cross-platform compatibility, the operating system and related software stack was generally made by the same company that designed the processors and the hardware system that used them. Linux and Windows Server, which jumped form the desktop to the datacenter after decades of hard pushing and platform buildout by Microsoft, provided portability and superior price/performance for many (but not all) workloads, and this finally broke the server software free of the server hardware.

  • Ma Bell, Not Google, Creates The Real Open Source Borg

    True to its name, Google’s famous Borg cluster controller has absorbed a lot of different ideas about how to manage server clusters and the applications that run atop them at the search engine and now cloud computing giant. And while the Kubernetes container controller that Google open sourced in June 2014 was certainly inspired by Borg, Kubernetes was really more of a kernel than it was a complete system, and the way you know that is that it took a long time to get Kubernetes to be truly usable in the enterprise.

    Oddly enough, Airship, a mashup of Kubernetes, the OpenStack cloud controller with bare metal extensions, and a slew of other open source projects spearheaded by AT&T – yes, the same Ma Bell that created the C compiler and then the Unix operating system back in 1969, starting the open source and Unix revolutions – has surprisingly and, at least to some, quietly created a complete software stack that arguably rivals Borg and its extensions inside of Google.

  • Containers, and why the future is open source

    Software containerisation is unlikely to be at the top of the list of considerations for the average storage administrator. First and foremost, storage professionals are going to be concerned with every enterprise’s most pressing problem: managing the “explosive” volume of data within the constraints of their limited IT budget.

    However, there are compelling reasons why storage professionals should be thinking about containerisation as its rapid adoption will impact the road map of your existing storage providers and drive changes to your own organisation’s data storage strategy.

    Let’s take a moment to get a basic understanding of what containerisation is all about, look a little deeper at those implications to your storage strategy and also discuss how open-source software-defined storage can help you with your data storage challenges.

    [...]

    Against this backdrop of the ever-growing communities of open-source developers, the limited development capability of isolated, commercially operated silos has little chance of long-term success. This is why it is clear – the future is open source.

Thinking big: Nextcloud chief aims to overtake Office365 and GSuite

Filed under

Web

The head of the open-source file syncing and sharing software company Nextcloud, which has been growing at a fast pace, has ambitions to overtake proprietary services like Office 365 and Google GSuite.

Founder and chief executive Frank Karlitschek told iTWire that, given these plans, the forthcoming Nextcloud releases would see big improvements in productivity, collaboration, communications, scalability and security.

Nextcloud was started as a breakaway from another company, ownCloud, that Karlitschek himself started in 2010. Asked about the split, which occurred in 2016, he said he did not want to dwell on the reasons for the break-up, but said: "At the end of the day the complete set-up of the old company was wrong. [It had] the wrong management, investors, product focus and strategy.

Has container hype jumped the shark?

Filed under
Server

You can't read tech news anymore without seeing containers everywhere. Containers have become the way for everyone to run their jobs on the cloud. And, to manage containers, Kubernetes is everyone's favorite. But, according to a Cloud Foundry, the open-source Platform-as-a-Service (PaaS) survey of CIOs and top-level programmers, developers are calling the IT shots, and they're getting a little tired of all containers all the time.

Instead, the report, Climbing up the Stack, found that while PaaS usage has jumped 6% in the last two quarters (41% to 47%), serverless usage and container usage are leveling at 14% and 37%, respectively. It's not that containers are going away. They're much too valuable for that happen.

  • NextCloud on Pi Adventures

    I spent yesterday *finally* setting up a NextCloud instance of my own. It’s been on my todo since I installed fiber at home and got a decent Internet connection.

    I started out with Rasbian Lite and combined it with the NextCloudPi install script from ownyourbits. I then used certbot to install certificates from let’s encrypt before migrating the data directory using these instructions.

    After that it was happy account creation time, before realizing that I could not upload files larger than ~10kB. Very annoying.

    Being practical most people are going to want to keep using Google services, but at least knowing what the issues are, how you can use privacy-enhanced versions or escape completely with your own services is good to know. While Nextcloud is so slick these days and with pre-packaged options it’s certainly fun just to try out, if not deployed as a full-time personal cloud solution.

Open source database use is a growing trend

Filed under

OSS

Open source databases are a growing segment of the overall database management system market, but according to a new survey, users are working with multiple databases adapted for specific purposes and not looking at single databases as multi-purpose.

The Open Source Data Management Software survey was conducted by Percona, a vendor based in Raleigh, N.C. that provides supported versions of multiple open source database platforms including PostgreSQL, MySQL and MongoDB.

Some 92% of survey respondents saying they are using multiple database technologies, with 89% using more than one open source database platform. The study, conducted earlier this year, also found that cloud deployments are a growing trend, with more than 50% running at least one workload in the public cloud.

"It's hard for one database to do everything well, so the trend is definitely to use the best database for the job, rather than try and fit into a single technology," said Matt Yonkovit, chief experience officer at Percona.

  • How to use containers with an eye on security

    Containers are all the rage. With good reason. With containers, your company’s apps and service deployments become considerably more agile, more reliable, and even more secure. This is true for software development companies (who develop apps and services for other businesses), as well as companies looking to roll out web-based and mobile applications with an unheard of speed and reliability.

    But with any new technology, comes hurdles. One of the biggest hurdles for any business is security. Data breaches have become rampant and it’s on the shoulders of every company to do everything in their power to make sure they are rolling out technology that is as secure as possible. This idea should certainly be applied to containers.

    But what can you do to use containers security? Fortunately, there are a few steps that you can take from the very beginning.

    While normally we don't cover hardware start-ups on Phoronix, Pensando Systems has just exited stealth and given their focus will be heavily involved with Linux and in fact already have their first kernel driver mainlined.

    After announcing a $145 million (USD) Series-C round, Pensando Systems exited "stealth" and revealed the first details of what they are trying to achieve with this company led by many ex-Cisco staff.

    [...]

    Pensando has been on our radar since as I wrote about last month when they were just a stealth networking startup they already upstreamed their first Linux kernel driver. In the Linux 5.4 kernel is a Pensando "Ionic" driver for a family of network adapters. In this week's press release, Pensando didn't specifically call out Ionic but presumably is the backbone to their hardware. Now that they are beginning to talk about their ambitions, hopefully we see more Linux kernel patches from them soon.

Dodging derailment by SUSE, OpenStack Train is scheduled to arrive this week

SUSE

With its OpenInfrastructure summit mere weeks away, the OpenStack gang is emitting its next release in the form of "Train" with a focus on data protection and machine learning.

The release comes after foundation platinum member SUSE threw in the towel over OpenStack Cloud in order to move on to a bright, Kubernetes-based future.

Not that the "S" word was mentioned, even in a waveringly high-pitched tone, as OpenStack readied Train ahead of a release expected on 16 October.

As is the norm, OpenStack was keen to shout about the more than 25,500 accepted code changes this time around, from 1,125 developers over 150 organisations. A glance at the content of the release shows that OpenStack is as bewilderingly vast as ever, although a number of tweaks merit closer attention.
