  • Ruby in Containers

    Software changes environments from a development machine to a UAT (user acceptance testing) server environment or even from a test environment to production. It is required that the software runs consistently and reliably in these environments in the process.

    There was a time when deploying software was an event, a ceremony because of the difficulty that was required to keep this consistency. Teams spent a lot of time making the destination environments run the software as the source environment. They thereafter prayed that the gods kept the software running perfectly in production as in development.

    With containers, deployments are more frequent because we package our applications with their libraries as a unit making them portable thereby helping us maintain consistency and reliability when moving software between environments. For developers, this is improved productivity, portability and ease of scaling.

    Because of this portability, containers have become the universal language of the cloud allowing us to move software from one cloud to another without much trouble.

    In this article, I will discuss two major concepts to note while working with containers in Ruby. I will discuss how to create small container images and how to test them.

  • Kubernetes co-founder on the container revolution and the future of VMs

    Containers have exploded in popularity in recent years. To help with the deploying, scaling, and managing of containerized applications, Brendan Burns co-founded Kubernetes - a production-grade container orchestration system. In this episode, Brendan shares how he and his co-founders came up with the idea, how they got started, and what containers mean for the future of Virtual Machines.

  • FOSS Project Spotlight: BlueK8s

    Kubernetes (aka K8s) is now the de facto container orchestration framework. Like other popular open-source technologies, Kubernetes has amassed a considerable ecosystem of complementary tools to address everything from storage to security. And although it was first created for running stateless applications, more and more organizations are interested in using Kubernetes for stateful applications.

    However, while Kubernetes has advanced significantly in many areas during the past couple years, there still are considerable gaps when it comes to running complex stateful applications. It remains challenging to deploy and manage distributed stateful applications consisting of a multitude of co-operating services (such as for use cases with large-scale analytics and machine learning) with Kubernetes.

  • How to choose the right storage solution for your containers

    We talk to many shops that are adopting, or have adopted, DevOps practices. For many companies, staying ahead of disruption means not only delivering new applications but also optimizing (or changing!) current processes and systems. They are moving to team-based cultures, working in smaller increments, and automating their environments to try to increase the velocity for software development and deployment.

    Having a common storage underpinning that is "self-service" for developers to provision and manage storage for their applications means teams have less friction in developing and shipping applications.

Ubuntu

Enterprises have embraced the cloud; and now they’re focusing on open source.

Open source lends itself to innovation, something competing enterprises need to seriously tap into, by allowing different developers from across the world to create and modify software to solve current challenges and open new avenues.

To find out more about how open source is venturing into the enterprise community and spurring digital innovation, Information Age spoke to Stephan Fabel, director of product at Canonical, the company behind Ubuntu.

  • How AT&T Is Using OpenStack to Deploy 5G Networks

    The next generation of wireless networks known as 5G is being enabled at AT&T through a series of open source efforts, including the OpenStack cloud platform.

    At the OpenStack Summit in Berlin, Germany, executives from AT&T discussed how they are building out 5G networks and also demonstrated a live 5G phone call running on top of an OpenStack deployment.

    "5G is a revolution. The capabilities that 5G will enable are things that will be a step function increase in latency, in reliability and resiliency with ultra-low latency and at very high speeds." Amy Wheelus, vice president, Network Cloud at AT&T, said. "5G Is really more than just another generation; it's more than just another G, because 5G is going to enable new services, new products, and even new industries that you and I haven't even thought about that today."

    She noted that among the 5G application use cases are smart factories and autonomous vehicles. AT&T also expects that 5G will be used for augmented reality, not just for entertainment, but also for critical functions, such as search and rescue or troubleshooting at the top of a tower.

  • OpenStack Expands Focus to Enable Open Infrastructure

    The OpenStack Foundation is no longer exclusively focused on its namesake cloud platform as the open-source effort is now expanding to enable the broader realm of open infrastructure.

    In a video interview at the OpenStack Summit here, Mark Collier, chief operating officer, and Jonathan Bryce, executive director of the OpenStack Foundation, detailed the group's new approach. It's an approach that now includes four pilot projects outside of the core OpenStack cloud platform—the Airship code deployment, Kata containers, StarlingX edge compute and Zuul continuous integration projects.

  • Getting Clarity on the Private vs. Public Cloud Decision

    News flash: Private cloud economics can offer more cost efficiency than public cloud pricing structures.

    Private (or on-premises) cloud solutions can be more cost-effective than public cloud options, according to "Busting the Myths of Private Cloud Economics," a report 451 Research and Canonical released Wednesday. That conclusion counters the notion that public cloud platforms traditionally are more cost-efficient than private infrastructures.

    Half of the enterprise IT decision-makers who participated in the study identified cost as the No. 1 pain point associated with the public cloud. Forty percent mentioned cost-savings as a key driver of cloud migration.

    "We understand that people are looking for more cost-effective infrastructure. This was not necessarily news to us," said Mark Baker, program director at Canonical.

  • ​OpenStack: Beyond the cloud

    Kata "Containers" is something of a misnomer. Rather than true containers, such as LXC, Kara Containers are lightweight VMs designed to feel and perform like containers. Why bother? Eric Ernst, an Kata Containers Architecture Committee member, explained, they "provide the workload isolation and security advantages of VMs."

  • 6 Best Practices for High-Performance Serverless Engineering

    When you write your first few lambdas, performance is the last thing on your mind. Permissions, security, identity and access management (IAM) roles and triggers all conspire to make the first couple of lambdas, even after a “hello world” trial just to get your first serverless deployments up and working. But once your users begin to rely on services your lambdas provide, it’s time to focus on high-performance serverless.

Meet TiDB: An open source NewSQL database

OSS

As businesses adopt cloud-native architectures, conversations will naturally lead to what we can do to make the database horizontally scalable. The answer will likely be to take a closer look at TiDB.

TiDB is an open source NewSQL database released under the Apache 2.0 License. Because it speaks the MySQL protocol, your existing applications will be able to connect to it using any MySQL connector, and most SQL functionality remains identical (joins, subqueries, transactions, etc.).

Step under the covers, however, and there are differences. If your architecture is based on MySQL with Read Replicas, you'll see things work a little bit differently with TiDB. In this post, I'll go through the top five key differences I've found between TiDB and MySQL.

  • OpenStack Expands With New Projects, Canonical’s CEO Is Not Thrilled About It

    For those who have been paying attention (and SDxCentral has been), the OpenStack Foundation has been expanding its scope beyond the basic compute, storage, and networking sub-projects of its cloud infrastructure software. Today at the OpenStack Summit in Berlin the group made it official, announcing that it will host new open source projects with a new governance framework.

    The OpenStack Foundation board approved the governance framework to incubate new pilot projects that are relevant to the open infrastructure community. As part of this new framework, the first four pilot projects are Kata Containers, Airship, Zuul, and StarlingX. All of these projects have been previously announced.

  • Open source is growing up – and here’s how

    If you’re among those who still think that open source is just for hobbyists and academics, think again. Open source is mature now, both as a concept and as tools for building enterprise IT, and we have two major shifts in understanding to thank for that.

    The first key change is that there’s a much more mature understanding now of how the layers of IT architecture relate to each other – of what fits where, in other words. Instead of trying to do too much, adding in every feature or capability that might be related, open source projects have become more focused.

    For example, instead of misunderstanding them as rivals, we can now see OpenStack and Kubernetes for what they are. The former is an infrastructure layer, upon which you can run platform layers such as the latter.

  • Open-source and cloud-native, Kubernetes paves the way for new companies to bring DevOps to data

    With less than two months left, 2018 is poised to go down in tech history as the coming of age for open-source software.

    Need evidence? Over the past 10 months, notable open-source enterprises MuleSoft Inc., Magento Inc., GitHub Inc. and Red Hat Inc. have been purchased for a combined $50 billion.

    Yet before jumping on the open-source bandwagon, observers would be wise to keep in mind that these technologies still depend on a sizable community of contributors to keep innovation fresh, and monetization of many open-source projects remains a struggle. So what is all the fuss about?

  • Red Hat OpenStack Platform 14 coming soon with tighter Kubernetes integration

    Today, Red Hat has announced Red Hat OpenStack Platform 14, saying it will become available in the coming weeks. The firm says that the latest version, which is built on the OpenStack “Rocky” community release, more tightly integrates with the Red Hat OpenShift Container Platform which gives admins full control over their Kubernetes environments.

  • Red Hat commits to Openstack for 'at least' 10 years

    While Red Hat understandably wouldn't discuss anything to do with the IBM mega-acquisition - for regulatory reasons - director of product management James Labocki and senior director for product management at Openstack Nick Barcet confirmed Red Hat's commitment to Openstack for at least the next "10 years".

    The open source giant today announced Openstack Platform 14, which Barcet said aimed to make Openstack a better platform to run container orchestration system Kubernetes on, while also helping to better manage the deployment of Red Hat's container platform OpenShift on bare metal, as well as easing the integration of OpenShift and Openstack at the networking and storage layer. This, says Barcet, is a landmark move for Red Hat because it is part of a new strategy to focus on its whole portfolio as a single entity rather than individual products.

  • HelpSystems Gets Into JAMS for Scheduling

    HelpSystems yesterday announced the acquisition of MVP Systems Software, the Connecticut-based developer of the JAMS workload management and scheduling software. While JAMS supported IBM i, HelpSystems will count on the product to deliver capabilities primarily in the open systems realm, with cloud possibilities looming in the future.

    The acquisition came together as the result of mutual respect that HelpSystems and MVP Systems Software had for each other, says Kate Bolseth, general manager of cross platform products at HelpSystems.

  • What's the reality of OpenStack and public cloud?

    My colleague, Margaret Dawson, spends a lot of time talking with customers. And in those conversations, questions about cloud and OpenStack invariably come up. She shared this message a while back, during her keynote at the OpenStack Summit in Vancouver, and it still resonates. While public cloud looms large in many companies’ plans, OpenStack’s future looks bright in the hybrid cloud reality we see today -- and tomorrow.

    “Most of you, especially if you’ve been working on OpenStack for a while, hear ‘Game’s over. Why are we even still doing this? AWS has won, so let’s just put everything in the public cloud and call it a day.”

  • Impact of IBM-Red Hat Merger

    Recently, there have been numerous machine learning, and AI algorithms developed to achieve the desired output in a dynamic, efficient, and effective manner. However, in a real-time scenario, an individual algorithm has its own advantages and is restricted to certain limitations. These limitations can be minimized by integrating different algorithms to achieve the desired task. By capturing the insights into the integral approach, IBM has announced its acquisition of Red Hat technologies to enhance its cloud-based business services to its clients.

    In the past year, nearly a quarter of IBM overall revenue was achieved through the cloud service platform. But with an increase in competitors, the company was overshadowed by other cloud rivals such as Microsoft and Amazon. Ginni Rometty, CEO of IBM, stated that at present, only 20 percent of the companies are renting cloud services to cut costs; over 80 percent are still unlocking their business values and can shift their business applications to the hybrid cloud in the near future for data extraction and optimization.

Mozilla Firefox and Google Chrome: Net Neutrality Stance, Mozilla, a VR Work, Firefox Monitor and 5 Best Chrome Extensions For Productivity

  • Mozilla Fights On For Net Neutrality
    Mozilla took the next step today in the fight to defend the web and consumers from the FCC’s attack on an open internet. Together with other petitioners, Mozilla filed our reply brief in our case challenging the FCC’s elimination of critical net neutrality protections that require internet providers to treat all online traffic equally. The fight for net neutrality, while not a new one, is an important one. We filed this case because we believe that the internet works best when people control for themselves what they see and do online. The FCC’s removal of net neutrality rules is not only bad for consumers, it is also unlawful. The protections in place were the product of years of deliberation and careful fact-finding that proved the need to protect consumers, who often have little or no choice of internet provider. The FCC is simply not permitted to arbitrarily change its mind about those protections based on little or no evidence. It is also not permitted to ignore its duty to promote competition and protect the public interest. And yet, the FCC’s dismantling of the net neutrality rules unlawfully removes long standing rules that have ensured the internet provides a voice for everyone. Meanwhile, the FCC’s defenses of its actions and the supporting arguments of large cable and telco company ISPs, who have come to the FCC’s aid, are misguided at best. They mischaracterize the internet’s technical structure as well as the FCC’s mandate to advance internet access, and they ignore clear evidence that there is little competition among ISPs. They repeatedly contradict themselves and have even introduced new justifications not outlined in the FCC’s original decision to repeal net neutrality protections.
  • Virtual meeting rooms don’t have to be boring. We challenge you to design better ones!
    Mozilla’s mission is to make the Internet a global public resource, open and accessible to all, including innovators, content creators, and builders on the web. VR is changing the very future of web interaction, so advancing it is crucial to Mozilla’s mission. That was the initial idea behind Hubs by Mozilla, a VR interaction platform launched in April 2018 that lets you meet and talk to your friends, colleagues, partners, and customers in a shared 360-environment using just a browser, on any device from head-mounted displays like HTC Vive to 2D devices like laptops and mobile phones. Since then, the Mozilla VR team has kept integrating new and exciting features to the Hubs experience: the ability bring videos, images, documents, and even 3D models into Hubs by simply pasting a link. In early October, two more useful features were added: drawing and photo uploads.
