Recently, I spotted a question on a mailing list asking how to move container images from an internal/build registry to a production one. To put it another way: how would you copy images from registry A to registry B? I’m going to show you a really easy way to do this with skopeo.
Is your server running slowly?
Has your network tuning run amuck?
Is Red Hat OpenShift not scaling for you?
If you’re attending Red Hat Summit, whatever your performance
In the world of heterogeneous data centers – having multiple operating systems running on different hardware platforms (and architectures) is the norm. Even traditional applications and databases are being migrated or abstracted using Java and other interpreted languages to minimize the impact on the end user, if they decide to run on a different platform.
Consider the common scenario where you have both Windows and Linux running in the data center and you need your Linux application to talk to Microsoft SQL Server and get some existing data from it. Your application would need to connect to the Windows server that is running the SQL Server database using one of many available APIs and request information.
While that may sound trivial, in reality you need to: know where that system is located, authenticate your application against it, and pay the penalty of traversing one or more networks to get the data back – all while the user is waiting. This, in fact, was “the way of the world” before Microsoft announced their intent to port MS SQL server to Linux in March of 2016. Today, however, you have a choice of having your applications connect to a Microsoft SQL Server that runs on either Windows or Linux
Today marks another milestone in the evolution of our flagship virtualization platform, Red Hat Virtualization (RHV), as we announce the release of version 4.1. There are well over 165 new features, and while I don’t have the space to cover all of the new features, I would like to highlight some of them, especially in the area of integration. But first I’d like to put that integration into perspective.
Virtualization remains foundational and firmly rooted in the modern data center. Whether a particular application is better suited for “scale up” or virtualization simply fits the business and technology model for a given data center, virtualization as an infrastructure platform is not going away anytime soon.
This year in Boston, MA you can attend the Red Hat Summit 2017, the event to get your updates on open source technologies and meet with all the experts you follow throughout the year.
It’s taking place from May 2-4 and is full of interesting sessions, keynotes, and labs.
This year I was part of the process of selecting the labs you are going to experience at Red Hat Summit and wanted to share here some to help you plan your hands-on time with infrastructure and operations focused labs. These labs are for you to spend time with the experts who will teach you hands-on how to get the most out of your infrastructure and operations products.
Each lab is a 2-hour session, so planning is essential to getting the most out of your days at Red Hat Summit.
As you might be struggling to find and plan your sessions together with some lab time, here is an overview of the labs you can find in the session catalog for exact room and times. Each entry includes the lab number, title, abstract, instructors and is linked to the session catalog entry:
Previously in The Quest for Operations Intelligence, the focus was placed on what can be delivered with log aggregation and how to improve it. A conclusion was that to have full situational awareness on IT, you would need logs, metrics, configuration and events information correlated for easy one stop analysis when problems arise.
While we talked about logs, metrics and configuration in depth, we left events at the time without any sort of definition. What are events and what can we use them for in our quest for operations happiness?
We’re excited to announce our latest step in the further optimizing of Red Hat Enterprise Linux (RHEL) for containers with the release of the RHEL Atomic base image. This image is much smaller than the current RHEL base image, giving just enough to get started on building your application or service.
We carved out python, systemd, and yes, even Yum is gone – leaving you with only the bare bone essentials like glibc, rpm, bash, and their remaining dependencies. This leaves us with an image that’s just under 30MB compressed, 75MB on disk; composed of 81 packages.
In Part 1 of this series, we looked at core improvements for Identity Management (IdM) in Red Hat Enterprise Linux (RHEL) 7.3, as well as manageability and other improvements. In the second half, we’re going to look at interoperabilty, and Active Directory integration.
We’re pleased to announce the availability of QuickStart Cloud Installer (QCI) 1.1! This is the second release of QCI since its introduction on September 14, 2016.
Included with both Red Hat Cloud Suite and Red Hat Cloud Infrastructure entitlements, QCI is designed to simplify provisioning your private cloud infrastructure by orchestrating installation workflow across different products. Instead of installing each product in the suite separately, QCI provides an intuitive web-based graphical user interface for provisioning a fully functional cloud using any combination of components in
As covered in the previous article, The Quest for Operations Intelligence, we have very high expectations from any modern Cloud architecture applications deployed on Red Hat hybrid cloud solutions.
No matter how much support is put into place, the customer needs to be able to operate their hybrid clouds.
