Filed under
Server

I’m pleased to announce the release of the Xen Project Hypervisor 4.8. As always, we focused on improving code quality, security hardening as well as enabling new features. One area of interest and particular focus is new feature support for ARM servers. Over the last few months, we’ve seen a surge of patches from various ARM vendors that have collaborated on a wide range of updates from new drivers to architecture to security.

  • Docker acquires file syncing and sharing app Infinit, will open-source the software

    Docker, the startup that pushes open source software for packaging up code into containers that can be deployed on many machines, today announced its latest acquisition: file transfer app Infinit.

    Yes, that’s right, Docker bought a company with a consumer-friendly app. It lets you sync files to your other devices or send them to others.

  • How Virtualized Networks Will Save Us From Dropped Calls

    We’ve all been the victim of a dropped mobile phone call and know how frustrating it can be. However, virtualized networks provide network operators with powerful tools to detect and recover from network disruptions, or “faults,” that can drop calls for thousands of subscribers simultaneously. The Open Platform for Network Functions Virtualization (OPNFV) project together with OpenStack have developed features in software that add resiliency to mobile networks and enable them to recover from network and other outages.

  • It’s Brexploitation! Microsoft punishes UK for Brexit with cloud price-gouging

    “My own story would not have been possible but for the democratizing force of Microsoft technology reaching me where I was growing up,” CEO Satya Nadella told shareholders this week.

    But the price of that “democratizing force” is about to go up, with Britons uniquely singled out. Microsoft has reiterated to Azure customers that prices will go up by 22 per cent from January 1st.

    The problem? The price rise is far greater than any exchange rate post-Brexit fluctuations might justify. Microsoft’s biggest European data centre is in Dublin, a member of the Euro currency. The Euro hovered around €1.28 to one pound for the first six months of the year, before crashing after Brexit. It’s now €1.19, a depreciation of just 9 cents, or 7 per cent.

    The value of the British pound has weakened more dramatically against the US dollar, dropping by 18.9 per cent since 24 June - the day after Brits voted to leave the EU.

    For new Office or Azure cloud customers in the UK, no exchange rate can justify any price rise at all. In September, Microsoft made Azure available in UK data centres.

  • How We Knew It Was Time to Leave the Cloud

    In my last infrastructure update, I documented our challenges with storage as GitLab scales. We built a CephFS cluster to tackle both the capacity and performance issues of NFS and decided to replace PostgreSQL standard Vacuum with the pg_repack extension. Now, we're feeling the pain of running a high performance distributed filesystem on the cloud.

  • Docker for AWS Public Beta

    Today, we’re announcing that Docker for AWS is graduating to public beta, just in time for AWS re:Invent. Docker for AWS is a great way for ops to setup and maintain secure and scalable Docker deployments on AWS.

  • Amazon Lightsail: The private server killer

    Hosting companies, and their virtualized descendants -- virtual private server companies such as Bluehost, Digital Ocean, and Linode -- provide remote servers for developers, websites, and businesses needing other internet services. They continue to be very popular with small and medium sized businesses (SMBs) that can't afford or don't need a data center or public cloud services.

  • Trouble in paradise: Is the open-source community planning a revolt against Amazon?

    Things just keep looking up for Amazon. Attendance at this year’s AWS re:Invent conference broke the record; enterprise giants like McDonald’s are singing its praises on the keynote stage; and it has announced roughly 1,000 upcoming features and updates. And yet some foresee adversity ahead from both users and ecosystem players.

    Stu Miniman (@stu), co-host of theCUBE*, from the SiliconANGLE Media team, described the conference and Amazon’s announcements as “an embarrassment of riches.” With difficulty, he picked a handful of favorites, among them Greengrass.

    “Greengrass is how Amazon is taking their server-less architecture, really Lambda, and they’re taking it beyond the cloud,” he said. He explained that this technology has huge promise for IoT, which still struggles with the physics of moving data around. “They talked about the ‘snowball edge,’ which is going to allow me to have kind of compute and storage down at that edge,” he stated.

  • Outlook.com is still not functioning properly for some Microsoft punters

    Microsoft is still working to resolve "difficulties" faced by its Outlook customers, despite months of complaints about the disappearance of sent emails and 550 Errors.

    A growing number of complaints threads have been posted to Microsoft's questions page regarding Outlook after recent upgrades to the service. They both precede and follow last week's outage, which Redmond's PRs failed to explain to us.

  • OpenStack Becomes a Standard Building Block for NFV

    OpenStack is becoming the de facto standard for infrastructure orchestration for NFV deployment by leading Communications Service Providers (CSPs). CSPs are trading off the challenges of OpenStack implementations (e.g. immature technology and evolving standards) for the benefits of open source and open architectures (i.e. reduced vendor lock-in). Lack of standards for NFV management and orchestration (MANO) remains a leading impediment.

  • The Docker monitoring problem

    You have probably heard of Docker—it is a young container technology with a ton of momentum. But if you haven’t, you can think of containers as easily—configured, lightweight VMs that start up fast, often in under one second. Containers are ideal for microservice architectures and for environments that scale rapidly or release often.

    Docker is becoming such an important technology that it is likely that your organization will begin working with Docker soon, if it has not already. When we explored real usage data, we found an explosion of Docker usage in production: it has grown 5x in the last 12 months.

    Containers address several important operational problems; that is why Docker is taking the infrastructure world by storm.

    But there is a problem: containers come and go so frequently, and change so rapidly, that they can be an order of magnitude more difficult to monitor and understand than physical or virtual hosts. This article describes the Docker monitoring problem—and solution—in detail.

    We hope that reading this article will help you fall in love with monitoring containers, despite the challenges. In our experience, if you monitor your infrastructure in a way that works for containers—whether or not you use them—you will have great visibility into your infrastructure.

  • Docker 1.13.0 RC2 Supports Building of Docker DEBs for Ubuntu 16.10 on PPC64LE

    Two weeks ago, we discussed here the upcoming features of the Docker 1.13.0 open-source and cross-platform application container engine as part of the new version's first Release Candidate build.

    And now, Developer Victor Vieux announced the availability of the second RC version for the Docker 1.13.0 release, which appears to bring lots of improvements and bug fixes. Notable changes include support for labels on volumes, the ability to filter volumes by label, along with the ability to purge data from a deleted volume using the "--force" parameter in the "docker volume rm" command.

  • AWS Launches Amazon Linux Container Image

    AWS recently launched a Docker container image for its Amazon Linux operating system, complementing the EC2 specific Amazon Linux AMI with a versatile deployment option for custom cloud and on-premise environments. The image is available through the Amazon EC2 Container Registry (Amazon ECR), and also as an official repository on Docker Hub.

    The Amazon Linux AMI is a "supported and maintained Linux image provided by Amazon Web Services" that is designed to "provide a stable, secure, and high performance execution environment for applications running on Amazon EC2". It has long been the base image for most of AWS' Linux based offerings, such as the AWS Elastic Beanstalk platforms, the Amazon Elastic MapReduce releases, and the Amazon EC2 Container Service instances.

  • 3 Emerging Cloud Technologies You Should Know

    In previous articles, we’ve discussed four notable trends in cloud computing and how the rise of microservices and the public cloud has led to a whole new class of open source cloud computing projects. These projects leverage the elasticity of the public cloud and enable applications designed and built to run on it.

    Early on in cloud computing, there was a migration of existing applications to Amazon Web Services, Google, and Microsoft’s Azure. Virtually any app that ran on hardware in private data centers could be virtualized and deployed to the cloud. Now with a mature cloud market, more applications are being written and deployed directly to the cloud and are often referred to as being cloud native.

    Here we’ll explore three emerging cloud technologies and mention a few key projects in each area. For a more in-depth explanation and to see a full list of all the projects across six broad categories, download our free 2016 Guide to the Open Cloud report.

  • November 2016 Web Server Survey

    Outweighing the existing major vendors, LiteSpeed demonstrated the largest hostname growth after it gained more than 40 million sites – a remarkable 740% increase. LiteSpeed's growth included 38 million existing sites that were hosted by OVH, and previously using Taobao's Tengine web server, which consequently suffered the largest loss of sites this month. The sites involved in this movement—nearly all of which make use of the .science TLD—are now hosted by Amazon Web Services. As a result of these changes, LiteSpeed's market share of sites has leapt from 0.39% to 3.29%, taking it from 10th to 4th place – while Tengine has been displaced to 5th.

    [...]

    Using the less-volatile web-facing computers metric, Apache showed the largest growth this month with an increase of 39,900 computers, while nginx was not too far behind with net growth of 32,881. Despite LiteSpeed's large hostname growth, it gained only a modest sum of 312 computers (+3.4%), making it the 7th largest vendor by this metric.

  • Cumulus Networks Aims to Smooth Linux Networking Transition

    Interest in open source network operating systems based on Linux running on a bare-metal switch is high. But not many networking professionals are familiar with platforms based on Linux. To make it simpler to make the switch, Cumulus Networks has created a Network Command Line Utility (NCLU) that provides a central location from which they can manually manage the Cumulus Linux environment using a command-line interface most network administrators would easily recognize.

    Cumulus Networks CTO JR Rivers says the goal is to provide network managers with a means of making the switch to an open source networking environment using a tool that resembles the ones most of them currently use to manage proprietary networks.
