  • Parity Check: Expectations Around Monitoring Have Changed

    Monitoring software company BigPanda recently published its second annual State of Monitoring report, which provides data and a few answers. It is based on responses from over 1,500 IT pros. When comparing the 2017 and 2016 reports we found that many things have not changed. The top IT concerns are about security and downtime. The top IT monitoring challenges are quick remediation of service disruptions, getting money to buy monitoring tools and reducing the number of unimportant alerts being generated. Interestingly, even the top performance key performance indicators (KPIs) are the same, with customer satisfaction cited by 73 percent, followed service level agreements (SLAs) compliance, incident volume and mean time to repair (MTTR).

  • IT Automation Best Practices for Network Engineers and Architects

    Software-defined networking (SDN) for L2 and L3 (layer two and three) networking and network function virtualization (NFV) for L4-L7 network services have remained elusive for many IT departments due to the lack of maturation of the technology or specialized skills needed to implement them. But, network automation doesn’t have to be an all or nothing proposition. Software-defined approaches for application and networking services combined with scripting and orchestration tools such as Ansible are enabling practical approaches to network automation that doesn’t require boiling the ocean. In this article, I’ll examine some best practices for network automation in L4-L7 services that can drive immediate improvements in your network.

  • Serverless: Redefining DevOps

    There is a dramatic shift underway in how many in house, and commercial, DevOps tools are being created and used

    The growth in interest in serverless computing continues at pace, and for many organisations serverless technologies such as AWS Lambda, Azure Functions or Google Cloud Functions are becoming an essential part of their development and operations toolkit.

  • IT Workers Say Their Companies Are Migrating to Virtual Infrastructures, Study Says

    An overwhelming 86 percent of respondents to a Chef survey of IT practitioners have completed or are in the progress of migrating from a physical infrastructure to a virtual one.

    Chef interviewed more than 1,500 global IT workers that use Chef servers and found that many emerging and legacy technologies are being rebuilt around the needs of developers. In addition, companies are piloting and adapting new technologies like cloud, containers, and microservices in search of speed.

  • ARM Antes Up For An HPC Software Stack

    The HPC community is trying to solve the critical compute challenges of next generation high performance computing and ARM considers itself well-positioned to act as a catalyst in this regard. Applications like machine learning and scientific computing are driving demands for orders of magnitude improvements in capacity, capability and efficiency to achieve exascale computing for next generation deployments.

    ARM has been taking a co-design approach with the ecosystem from silicon to system design to application development to provide innovative solutions that address this challenge. The recent Allinea acquisition is one example of ARM’s commitment to HPC, but ARM has worked with the HPC community to develop compilers, libraries, and other key tools that are now available for ARM HPC deployments in 2017.

  • Mesosphere Extends Data Services Reach

    In general, Hsu says, IT organizations are making it clear that they need platforms that go well beyond merely orchestrating containers and images. Applications running in production environments require access to a full range of services that IT operations teams need to be able to manage at scale, he says. Container orchestration engines such as Kubernetes may meet the requirements of an individual developer, but most IT operations teams are looking manage multiple applications accessing hundreds of services that all need to be centrally managed, says Hsu.

Security Leftovers

  • How To Improve The Linux System’s Security Using Firejail
    As you already know, Linux kernel is secure by default. But, it doesn’t mean that the softwares on the Linux system are completely secure. Say for example, there is a possibility that any add-ons on your web browser may cause some serious security issues. While doing financial transactions over internet, some key logger may be active in browser which you are not aware of. Even though, we can’t completely give the bullet-proof security to our Linux box, we still can add an extra pinch of security using an application called Firejail. It is a security utility which can sandbox any such application and let it to run in a controlled environment. To put this simply, Firejail is a SUID (Set owner User ID up on execution) program that reduces the risk of security breaches by restricting the running environment of untrusted applications.

Containers vs. Zones vs. Jails vs. VMs

  • Setting the Record Straight: containers vs. Zones vs. Jails vs. VMs
    I’m tired of having the same conversation over and over again with people so I figured I would put it into a blog post. Many people ask me if I have tried or what I think of Solaris Zones / BSD Jails. The answer is simply: I have tried them and I definitely like them. The conversation then heads towards them telling me how Zones and Jails are far superior to containers and that I should basically just give up with Linux containers and use VMs. Which to be honest is a bit forward to someone who has spent a large portion of her career working with containers and trying to make containers more secure. Here is what I tell them:
  • [Old] Hadoop Has Failed Us, Tech Experts Say

    The Hadoop community has so far failed to account for the poor performance and high complexity of Hadoop, Johnson says. “The Hadoop ecosystem is still basically in the hands of a small number of experts,” he says. “If you have that power and you’ve learned know how to use these tools and you’re programmer, then this thing is super powerful. But there aren’t a lot of those people. I’ve read all these things how we need another million data scientists in the world, which I think means our tools aren’t very good.”

  • [Wine] Packaging changes
    Today we want to announce some important changes regarding the Wine Staging packages provided at repos.wine-staging.com and dl.winehq.org. We completely reworked our build system to make the packages available sooner after a release and also added some new features, like downloading old packages for Debian / Ubuntu. The complete list of changes can be found in the announcement email on the Wine mailing list.
