It has been over five years since the release of Red Hat Enterprise Virtualization 3.0. In just under 3 months (September 30) it will hit the end of it’s support lifecycle, and we will retire the 3.x version. At that same time, Red Hat Virtualization 4.0 will have been out for 13 months, and 4.1 for 5 months.
Twice a year the most prominent supercomputing sites in the world get to showcase their capabilities and compete for a Top500 spot. With Linux dominating the list, Red Hat is paying close attention to the latest changes that will be announced at International Supercomputing (ISC) show in Frankfurt, Germany between June 18 to June 22, 2017.
While supercomputers of the past were often proprietary, the trend of building them out of commodity components has dominated the landscape in the past two decades. But recently the definition of “commodity“ in HPC has been morphing. Traditional solutions are routinely augmented by various acceleration technologies, cache-coherent interconnects are becoming mainstream and boutique hardware and software technologies previously reserved for highly specialized solutions are being adopted by major HPC sites at scale.
Developing new and adapting existing highly scalable applications to take advantage of the new technological advances across multiple deployment domains is the greatest challenge facing HPC sites. This is where the operating system can provide
As predicted in one of my earlier posts, more and more customers are starting to seriously evaluate and move off of third party Active Directory integration solutions. They want to use or at least consider leveraging identity management technologies available in Red Hat Enterprise Linux.
In the calls and face to face meetings as well as during customer presentations at Red Hat Customer Convergence events, Red Hat Summit, Defence in Depth and other conferences I get a lot of questions about such migration. As it is becoming a common theme, I decided to consolidate some of the thoughts, ideas, and best practices on the matter in a single blog post.
The latest editions of Red Hat Software Collections and Red Hat Developer Toolset are generally available. Red Hat Software Collections 2.4 provide the latest set of open source web servers, web development tools, dynamic languages, and databases. Red Hat Developer Toolset 6.1 provides access to some of the latest, stable open source C and C++ compilers and related development tools.
As Red Hat engineers, we are always looking to incorporate features that empower administrators and decision makers. Our goal is to enable them to be proactive, efficient, and to help them maximize value from their infrastructure.
To this end, we are currently working on how to significantly improve the reporting and metrics API in Red Hat Virtualization Manager, our management platform for virtualized resources. Until recently, Red Hat Virtualization relied on native reports and data warehouse engines to provide
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:
