Feedback: Docker Networking Deep Dive

While the pundits keeps telling me Docker is dead (looking at its documentation I would say they’re right) and Kubernetes it the way to go (yay!), some people still have to deal with Docker networking, and at least some of them found the Docker Networking Deep Dive webinar useful. Here’s a recent review:

You can scroll over internet pages as long as you can, you will rarely find this kind of specialized knowledge. This is the next level in term of knowledge about Docker.

If you belong to the “Kubernetes will rule the world” camp, we have you covered as well: Stuart Charlton created a phenomenal Kubernetes Networking Deep Dive webinar (approximately half of it is already accessible with free subscription).

Roundup of server vendors using new Xeon processors

It’s only two years late, but the fourth generation of Xeon Scalable processors, aka Sapphire Rapids, is hitting the ground running, with every major OEM offering new servers featuring the chips.The 4th Gen Xeon Scalable is notable because it contains a number of specialty computing engines in addition to its x86 cores, and it also has lots of cores as well; up to 60. One of the special engines is for AI acceleration, as Intel is determined to make the CPU viable as an AI processor instead of GPUs. So not surprisingly, many of the new servers are built with AI processing in mind.To read this article in full, please click here

IBM boosts Power CPU core count…for Oracle

Last month, IBM quietly quietly announced it's planning to release a 24-core Power 10 processor specifically for the benefit of an Oracle database, and Oracle doesn’t know why.An announcement dated Dec. 13 called "a statement of general direction" detailed IBM’s plans around the Power S1014 server. The S1014 server is a single-socket, 4U rack mounted server with 16 NVMe SSDs and a maximum memory capacity of 64GB. The document said in part:"IBM intends to announce a high-density 24-core processor for the IBM Power S1014 system (MTM 9105-41B) to address application environments utilizing an Oracle Database with the Standard Edition 2 (SE2) licensing model. It intends to combine a robust compute throughput with the superior reliability and availability features of the IBM Power platform while complying with Oracle Database SE2 licensing guidelines."To read this article in full, please click here

Commands and settings for managing user accounts on Linux

If you’re administering a Linux server, chances are you have a lot of user accounts to manage and, along with these, a lot of files and settings to control. Here are some commands and issues that are important in setting up and managing user accounts and access rights.Dealing with IDs First, in managing user accounts, you need to be aware of both user IDs (UID) and group IDs (GID). Most accounts are set up with each user being the sole member of a group that has the same name as the user’s account. In fact, both are set up when an account is created using the useradd command. When you list a user’s home directory, you should see something like this:To read this article in full, please click here

AAP 2.3 Introducing Remote Execution Mesh Nodes for Openshift

phil blog 1

Last year Ansible Automation Platform (AAP) 2 introduced major changes around the mechanics on how automation is run. The main focus was to enhance the foundational pieces of the platform while providing flexibility and simplicity for automators to automate at enterprise scale. One of those foundational pieces introduced was automation mesh. 

Automation mesh provides a simple, flexible and reliable way to scale automation of large inventories across diverse network topologies, platforms and teams. It was important to evolve how the platform was developed, managed, operated to meet business demands and needs, for the large majority of customers.

 

Pre 2.3 Automation Mesh in OCP

Prior to AAP 2.3, the automation mesh was mostly a VM deployment base option and feature. I’ve tried to highlight the main differences between platform choices in this diagram:

We are now starting to level up the feature parity, and this brings remote mesh execution nodes to non-VM supported deployments. Before we look more at the new feature, let’s look at the options that were available before:

For VM based deployments, the automation mesh introduced horizontal scaling, the ability to scale your automation needs out, whether locally or globally. We did this by Continue reading

Full Stack Journey 074: Going The Distance – What Running Can Teach Us About Careers

On today's Full Stack Podcast, Scott is joined by Krithika Chandramouli, a software engineer at Meta, to discuss how the lessons she learned while preparing to run her first-ever half-marathon also apply to careers.
