Deploying a UPI environment for OpenShift 4.1 on vSphere NOTE: THIS PROCESS IS NOT SUPPORTED BY RED HAT AND IS PROVIDED “AS-IS”. This process will utilize terraform to deploy the infrastructure used by the OpenShift Installer. This article was created utilizing Terraform v0.11.12. CREATE THE APPLICABLE DNS RECORDS FOR THE OPENSHIFT DEPLOYMENT. Take note of the SRV records for etcd. Also, examine the bootstrap-0 DNS records: host, api and api-int. To learn more about required DNS the OpenShift docs discuss further. CREATE A WORKING INSTALL-CONFIG FILE FOR THE INSTALLER TO CONSUME Download the latest 4.1 installer and client from the repository.

The critical role of Internet of Things infrastructure in connecting all of our devices

Article | February 20, 2020

The Internet of Things (IoT) will fundamentally change all industries, from agriculture to transportation to healthcare. In the next few decades, nearly everything in our world will become connected. But with that increased connectivity comes several concerns. For example, the IoT will generate immense amounts of data, which will put pressure on the Internet and force us to come up with more efficient ways to transmit and store this data. Perhaps chief among these concerns are the infrastructure considerations as other sectors grow thanks to the IoT. Below, we've outlined the future of IoT infrastructure management, along with some IoT infrastructure companies that are leading the way.

5 Essential Principles for Managing SD-Branch Security

Article | February 20, 2020

Software-defined wide-area networking (SD-WAN) is revolutionizing the way that local branches are managed. As we’ve previously pointed out in our article on 4 things you should know about SD-Branch, it is being used to enable faster cloud adoption and greatly improve centralized control over the systems running in branch offices. Unfortunately, these advantages also come with some downsides. As SD-WAN has developed in SD-Branch, the number of IoT and end-user devices connected to these networks has grown exponentially. This means that the surface attack area of the average SD-Branch setup has increased enormously over the past few years. At the same time, business-critical applications are now sharing more data than ever over broadband internet connections, exposing critical data to interception or disruption.

To cloud or not to cloud . . . that shouldn’t be the question

Article | February 20, 2020

In my discussions with clients about their journey to cloud, it’s becoming evident that many of them are viewing cloud as a goal, instead of looking at cloud deployments as a capability. In some cases, line-of-business owners are under corporate pressures to “adopt” a cloud-first strategy. A recent Forrester Consulting study commissioned by IBM, “The Key To Enterprise Hybrid Multicloud Strategy”[1] suggests that “75% [of 350 surveyed global decision makers] have received pushback while advocating for strategies outside of cloud environments.” The result of this, unfortunately, is the lack of continued investment on their on-premises (“on-prem”) environments. From my experience, this type of deployment focus may not yield the expected results. We shouldn’t think about problem solving as “To cloud or not to cloud?” Instead, we should ask ourselves, “What is the problem I’m trying to solve?” and “Are cloud deployments (public or private) going to optimize my solution?”

Benefits of Kubernetes on bare metal cloud infrastructure

Article | February 20, 2020

Bare metal cloud infrastructure is being introduced to run 5G applications in containers. This is a natural development of the shift the industry is going through from virtualized network functions to cloud native applications. But what are the benefits of running Kubernetes on a bare metal cloud infrastructure compared to a virtualized infrastructure? Let’s start with a brief recap on cloud native and CNCF – Cloud Native Computing Foundation. With the introduction of 5G, new use cases drive the need for designing applications based on containers and service-based architecture to address some technology gaps associated with virtualization. The most important technology gaps involve smoother software upgrades, automation and the realization of a CI/CD software pipeline to end customers.
