• Flock to Fedora 2019 Conference report

  Last week I attended “Flock to Fedora” conference in Budapest, Hungary. It was a Fedora contributors conference where I met some developers, project leaders, GSoC interns. Below is a brief report of my attendance.

• What salary can a sysadmin expect to earn?

  The path to reliable salary data sometimes is sometimes paved with frustration. That’s because the honest answer to a reasonable question—what should I be paid for this job?—is usually: "It depends."

  Location, experience, skill set, industry, and other factors all impact someone’s actual compensation. For example, there’s rarely a single, agreed-upon salary for a particular job title or role.

  All of the above applies to system administrators. It’s a common, long-established IT job that spans many industries, company sizes, and other variables. While sysadmins may share some common fundamentals, it’s certainly not a one-size-fits-all position, and it’s all the truer as some sysadmin roles evolve to take on cloud, DevOps, and other responsibilities.

  What salary can you expect to earn as a sysadmin? Yeah, it depends. However, that doesn’t mean you can’t get a clear picture of what sysadmin compensation looks like, including specific numbers. This is information worth having handy if you’re a sysadmin on the job market or seeking a promotion.

  Let’s start with some good news from a compensation standpoint. Sysadmins—like other IT pros these days—are in demand.

  "In today’s business environment, companies are innovating and moving faster than ever before, and they need systems that can keep up with the pace of their projects and communications, as well as help everything run smoothly," says Robert Sutton, district president for the recruiting firm Robert Half Technology. "That’s why systems administrators are among the IT professionals who can expect to see a growing salary over the next year or so."

• Run Mixed IT Efficiently, The Adient – SUSE Way.

  When you have multiple distributions, such as Red Hat and SUSE, you can reduce administration complexity and save administration time and resources with a common management tool. Adient had applications running on both SUSE Linux Enterprise Server and Red Hat Enterprise Linux. Adient deployed SUSE Manager to manage their Mixed IT environment involving both distributions.

• Package Management Domain Model

  When I wrote this model, we were trying to unify a few different sorts of packages. Coming from SpaceWalk, part of the team was used to wokring on RPMS with the RPM Database for storage, and Yum as the mechanism for fetching them. The other part of the team was coming from the JBoss side, working with JAR, WAR, EAR and associated files, and the Ivy or Maven building and fetching the files.

  We were working within the context of the Red Hat Network (as it was then called) for delivering content to subscribers. Thus, we had the concept of Errata, Channels, and Entitlements which are somewhat different from what other organizations call these things, but the concepts should be general enough to cover a range of systems.

  There are many gaps in this diagram. It does not discuss the building of packages, nor the relationship between source and binary packages. It also does not provide a way to distinguish between the package storage system and the package fetch mechanism.

  But the bones are solid. I’ve used this diagram for a few years, and it is useful.

This article only touches upon some of the main functions available in Cockpit. Managing storage devices, networking, user account, and software control will be covered in an upcoming article. In addition, optional extensions such as the 389 directory service, and the cockpit-ostree module used to handle packages in Fedora Silverblue.

The options continue to grow as more users adopt Cockpit. The interface is ideal for admins who want a light-weight interface to control their server(s).

Oracle is pleased to announce the general availability of Oracle Linux 7 Update 7. Individual RPM packages are available on the Unbreakable Linux Network (ULN) and the Oracle Linux yum server. ISO installation images will soon be available for download from the Oracle Software Delivery Cloud and Docker images will soon be available via Oracle Container Registry and Docker Hub.

• Linux and Cloud Computing: Can Pigs Fly? Linux now Dominates Microsoft Azure Servers [Ed: This is not about "Linux" dominating Microsoft but Microsoft trying to dominate GNU/Linux]

  Over the last five years things have changed dramatically at Microsoft. Microsoft has embraced Linux. Earlier in the year, Sasha Levin, Microsoft Linux kernel developer, said that now more than half of the servers in Microsoft Azure are running Linux.

• Google Cloud Adds Compute, Memory-Intensive VMs

  Google added virtual machine (VM) types on Google Compute Engine including second-generation Intel Xeon scalable processor machines and new VMs for compute- and memory-heavy applications.

• Kubernetes Ingress

  On a similar note, if your application doesn’t serve a purpose outside the Kubernetes cluster, does it really matter whether or not your cluster is well built? Probably not.

  To give you a concrete example, let’s say we have a classical web app composed of a frontend written in Nodejs and a backend written in Python which uses MySQL database. You deploy two corresponding services on your Kubernetes cluster.

  You make a Dockerfile specifying how to package the frontend software into a container, and similarly you package your backend. Next in your Kubernetes cluster, you will deploy two services each running a set of pods behind it. The web service can talk to the database cluster and vice versa.

• MongoDB 4.2 materialises with $merge operator and indexing help for unstructured data messes

  Document-oriented database MongoDB is now generally available in version 4.2 which introduces enhancements such as on-demand materialised views and wildcard indexing.

  Wildcard indexing can be useful in scenarios where unstructured, heterogeneous datasets make creating appropriate indexes hard. Admins can use the function to create a filter of sorts that matches fields, arrays, or sub-documents in a collection, and adds the hits to a sparse index.

  [...]

  Speaking of cloud, last year MongoDB decided to step away from using the GNU Affero General Public License for the Community Edition of its database and switched to an altered version. The Server-Side Public License is meant to place a condition – namely, to open source the code used to serve the software from the cloud – on offering MongoDB as a service to clients.

• Announcing New Course: DevOps and SRE Fundamentals-Implementing Continuous Delivery

  The Linux Foundation, the nonprofit organization enabling mass innovation through open source, announced today that enrollment is now open for the new DevOps and SRE Fundamentals – Implementing Continuous Delivery eLearning course. The course will help an organization be more agile, deliver features rapidly, while at the same time being able to achieve non-functional requirements such as availability, reliability, scalability, security, etc.

  According to Chris Aniszczyk, CTO of the Cloud Native Computing Foundation, “The rise of cloud native computing and site reliability engineering are changing the way applications are built, tested, and deployed. The past few years have seen a shift towards having Site Reliability Engineers (SREs) on staff instead of just plain old sysadmins; building familiarity with SRE principles and continuous delivery open source projects are an excellent career investment.”
