Red Hat Federation Story: Ipsilon & Keycloak… a “Clash of the Titans”

Some time ago, two different projects were started in the open source community, namely: Ipsilon and Keycloak. These projects were started by groups with different backgrounds and different perspectives. In the beginning, it seemed like these two projects would have very little in common… though both aimed to include

Identity Management and Application Integration

Identity management solutions integrate systems, services, and applications into a single ecosystem that provides authentication, access control, enterprise SSO, identity information and the policies related to those identities. While I have dedicated time to explaining how to provide these capabilities to Linux systems – it is now time to broaden the scope and talk a little bit about services and applications.

In some ways, services and applications are very similar. They are both usually

Why Now is the Perfect Time to Adopt Red Hat Enterprise Virtualization

IT decision makers seem to be up in arms regarding discussions on “next generation” technologies.  In the past three months it has been nearly impossible to hold a conversation where the terms cloud, OpenStack, or (Linux) containers don’t surface.  Hot topics and buzzwords aside, it has become clear (to me) that the right mix of market conditions are causing organizations to express a renewed interest in enterprise virtualization.

Many organizations are now ready to adopt the next generation of server hardware.  The popular Ivy Bridge and Sandy Bridge chipsets from Intel are four to five years old and those who purchased such hardware tend to refresh their equipment every four to five years.  In addition, we see Intel Haswell technology approaching its third anniversary.  Organizations that lease hardware on a three year cycle will also be looking at what the next generation of hardware has to offer.

What does a potential wave of hardware refresh have to do with a renewed interest in enterprise virtualization?  To no one’s surprise

Container Tidbits: When Should I Break My Application into Multiple Containers?

There is a lot of confusion around which pieces of your application you should break into multiple containers and why. I recently responded to this thread on the Docker user mailing list which led me to writing today’s post. In this post I plan to examine an imaginary Java application that historically ran on a single Tomcat server and to explain why I would break it apart into separate containers. In an attempt to make things interesting – I will also aim to

Connecting the Dots at Linaro Connect

Red Hat has long advocated for the importance of cross-industry IT standards, with the intention of enabling ecosystems with broad industry participation and providing a common basis for innovation. Perhaps even more importantly, these standards can help drive adoption of new technologies within enterprises, pushing the cycle of innovation even further along.

With ARM being one of these emerging ecosystems, we wanted to provide a snapshot of a recent event that highlights some of the standards-based work happening in this growing community: last week’s Linaro Connect conference in Bangkok, Thailand.

Why is Indirect Integration Better?

In last year’s blog series, I covered both direct and indirect Active Directory integration options. But I never explained what we actually suggest / recommend. Some customers looking at indirect integration saw only the overhead of providing an interim server and the costs related to managing it. To be clear, these costs are real and the overhead does exist. But we still recommend

Yogi Berra, Predictive Analytics, and SAP HANA Running on Red Hat Enterprise Linux for SAP HANA

Yogi Berra, the late baseball great and oft-quoted source of humorous statements about the condition of the world, once said, “It’s tough to make predictions, especially about the future.” Some of his most celebrated remarks were eerily prescient on the subject of using technology to predict the future. As many IT managers today ponder the best way forward with predictive analytics, it might be interesting to think about it from his perspective. Consider predictive analytics in the context of the following classic Yogi-isms

When to Migrate: Red Hat Identity Management vs. Third-Party Solutions

Over last several months, in meetings with many Red Hat customers, I have been asked about best practices related to migration from an existing third-party identity management solution to Red Hat’s Identity Management (IdM) solution. In today’s post I will share some of my thoughts on this matter…

Test Driving OpenShift with the Red Hat Container Development Kit (CDK)

Setting up a local development environment that corresponds as close as possible to production can be a time-consuming and error-prone task. However, for OpenShift deployments, we have the Red Hat Container Development Kit (CDK) which does a good job at solving this and also provides a great environment for experimenting with containers and the Red Hat container ecosystem in general.

In this blogpost we will cover deploying applications using the OpenShift Enterprise PaaS that comes with the CDK. The whole process will be driven via the OpenShift CLI, in contrast to our last post which focused on OpenShift’s web interface. If you haven’t yet installed the CDK, check out the previous blog post for instructions.

By the end of this article you will know how to build existing applications on OpenShift, whether they already use
