CoreOS, OCI Unveil Controversial Open Container Industry Standard

Filed under
OS
Server

CoreOS and the Open Container Initiative on Wednesday introduced image and runtime specifications largely based on Docker's image format technology.

However, OCI's decision to model the standard on Docker's de facto platform has raised questions. Some critics have argued for other options.

Version 1.0 provides a stable standard for application containers, according to Brandon Philips, CTO at CoreOS and chair of the OCI Technical Oversight Board.

Why you should become a sysadmin

Filed under
GNU
Linux
Server

Chances are good that you are already an administrator for some systems you own, and you do it for free because that's just how it goes these days. But there are employers willing and eager to pay good money for someone to help administer their systems. We're currently near zero unemployment in system and network administration, and the Bureau of Labor Statistics projects continued 9% growth in the field through 2024.

What about automation, you ask. Perhaps you've heard sysadmins say how they intend to automate away their entire job, or how they automated their predecessor's job in a single shell script. How many have you heard of that succeeding? When the job is automation, there is always more to automate.

If you attend or watch videos of sysadmin conferences, you'll see a field that needs new blood. Not only is there a distinct lack of younger people, but also fairly extreme gender and racial imbalances. While those are topics for a different article, diversity is well proven to improve resilience, problem-solving, innovation, and decision-making—things of great interest to sysadmins.

Server: Containers, Cloud Native, Microservices, and Google Cloud Platform (GCP)

  • It’s an ever more open world. How containers and open source will transform the data centre beyond recognition

    The value of open source is changing business roadmaps previously built on fixed terms. More control, end of vendor lock-in and constant updates are just some of the benefits of the open world, Abby Kearns, executive director at the Cloud Foundry Foundation tells João Marques Lima.

  • Observability for Cloud Native

    Although JSON/YAML Kubernetes manifests are straightforward to read and write, they are not always the best way to manage applications on your cluster. If you have a complex, production system and want to modify its deployment with existing approaches, you may experience significant operational costs.

  • Decentralizing Your Microservices Organization

    Adaptability — the ability to quickly and easily change — has become a primary goal for modern businesses and has put pressure on technology teams to build platforms that are easier and less costly to change.  Working in such environments, these teams have been attracted more and more to the microservices style of software architecture.  What attracts them is the promise of a method for expediting changes to software, without introducing unnecessary danger to the business.

  • Google Cloud Platform expands to London

    With 43 zones, Amazon Web Services (AWS) is the globe's largest public cloud, but Google is working hard to match AWS. On July 13, Google opened its latest region, Google Cloud Platform (GCP) London (europe-west2).

    This is Google tenth region and joins its existing European region in Belgium. The London GCP center will have three zones. It will offer compute, big data, storage, and networking service.

    Google expects its new region to greatly improve network performance for British Isles and Western Europe clients. In cities such as London, Dublin, Edinburgh, and Amsterdam, Google's performance testing shows 40-percent to 82-percent reductions in round-trip time latency when serving customers from London compared with the Belgium region.

Why Is Docker So Popular? Explaining the Rise of Containers and Docker

Filed under
Server

By now, you've almost certainly heard of Docker containers. You know Docker is massively popular. But do you know why? Here's a look at the factors driving tremendous interest in Docker today.

Before delving into a discussion of the factors behind Docker's popularity, it's worth noting that Docker is not the only container platform out there. Nor was it the first to come along.

Other frameworks, like OpenVZ and LXC, were available starting in the mid-2000s. Other container-like technologies, such as FreeBSD jails, go back even further. Docker was released only in 2013, making it a very young technology compared to most of today's mainstream enterprise technologies.

Curiously, however, it was Docker, not a more mature container platform, that has risen to massive prominence over the past few years. That's an outcome worth pondering -- for the purposes both of understanding what makes containers in general so popular, as well as why Docker in particular has succeeded so spectacularly, whereas alternative container frameworks have seen little adoption.

Ceph: Block Storage for the 21st Century

Filed under
Server

Storage used to be so simple. You had a Single Large Expensive Drive (SLED) and you stored all your data on it.

Then, we moved on to redundant arrays of inexpensive disks (RAID), and things got more complex. But, it was still pretty easy. Unless you were using Small Computer System Interface (SCSI). I still get the heebie-jeebies thinking about chaining SCSI drives together.

But, even as hard drives were replaced by solid-state drives (SSD), physical drives couldn’t keep up with modern server data needs, never mind those of clouds and containers. This is where Ceph, and software-defined storage (SDS) have stepped in.

How Linux containers have evolved

Filed under
Linux
Server

In the past few years, containers have become a hot topic among not just developers, but also enterprises. This growing interest has caused an increased need for security improvements and hardening, and preparing for scaleability and interoperability. This has necessitated a lot of engineering, and here's the story of how much of that engineering has happened at an enterprise level at Red Hat.

  • Kubernetes 1.7: Security Hardening, Stateful Application Updates and Extensibility

    Today we’re announcing Kubernetes 1.7, a milestone release that adds security, storage and extensibility features motivated by widespread production use of Kubernetes in the most demanding enterprise environments. 

    At-a-glance, security enhancements in this release include encrypted secrets, network policy for pod-to-pod communication, node authorizer to limit kubelet access and client / server TLS certificate rotation.

  • [Older] Moby and LinuxKit Open Source from Docker

    At the recent DockerCon event in Austin, Docker Inc announced two significant open source projects, Moby and LinuxKit. Moby essentially marks the split of Docker, the open source project from Docker Inc the company, with the docker/docker GitHub repo moved to moby/moby. LinuxKit provides a set of tools to build 'custom Linux subsystems that only include exactly the components the runtime platform requires'.

  • [Older] Docker Downsides: Container Cons to Consider before Adopting Docker

    Docker containers are massively popular -- and for good reason. But like any technology, Docker is not a silver bullet. It has its downsides, and it's important to understand them if you're considering migrating to Docker.

    Let me be clear that I think Docker is a great platform for many use cases. Docker containers are an excellent way to deploy microservices-based applications that are more modular and easier to manage. There are also security benefits to using containers, and containers consume system resources more efficiently.

    On 7th of October in Prishtina, Kosova’s capital, was hosted the first mini deb conference. The MiniDebConf Prishtina was an event open to everyone, regardless of their level of knowledge about Debian or other free and open source projects. At MiniDebConf Prishtina there were organized a range of topics incidental to Debian and free software, including any free software project, Outreachy internship, privacy, security, digital rights and diversity in IT.

This shell script uses text-browser to query and render Wikipedia articles. The output will be printed to standard out. It Currently supports around 30 Wikipedia languages. Most of us prefer Wikipedia to know the detailed information about any company or any product information & it’s history. For any google search by default Wikipedia link comes in Top 5.
