For many years, software virtualization has allowed retailers to deliver improved store-based applications without the need to add hardware capacity. Customer-facing applications such as stock control and customer loyalty programs, and colleague-facing applications such as replenishment and staff rotas are critical to store success. As the number and complexity of store applications increases, retailers will…

It’s easy to tick the checkboxes on a compliance checklist with the mindset that your system is protected and not exposed to risk. If it is this simple, why do we continue to invest billions of dollars in developing security controls and software development lifecycle (SDL) practices that help harden software and minimize risk? What…

It can’t be almost January yet. As the new year approaches, it’s time to reflect on the top learning paths Red Hat Developer published this year, along with highlighting key paths that were too new to make the list. No matter what kind of developer you are, it can be difficult enough to keep up with…

Hosted control planes (HCP) is the name of the Red Hat product for the upstream HyperShift project. It allows you to deploy the control plane of a Red Hat OpenShift cluster into an OpenShift project instead of requiring dedicated (master) nodes and attach worker nodes managed via the nodePool API to it. Hosted control planes architecture has several advantages when…

As cloud-native infrastructure evolves, managing Red Hat OpenShift clusters demands greater scalability and efficiency. Hosted control planes (HCP) represent a transformative approach in OpenShift, decoupling control planes and hosting them in lightweight, flexible pods. This innovation enhances resource utilization, multi-tenancy, and hybrid-cloud capabilities—key priorities for modern infrastructure. Learn more about Shift-On-Stack enhanced with hosted control…

The Time Zone Database Package (tzdata) provides Red Hat Enterprise Linux (RHEL) with the time zone information needed for all applications or runtimes in the operating system to print local time correctly. The GNU C Library (glibc) uses the tzdata package, so APIs like strftime() work correctly, while applications such as /usr/bin/date use this information to print the local…

2025 is fast approaching, but we have just enough time left to take a look at 2024’s most popular articles on application development, as well as some standout learning paths and e-books. The top 10 most popular app dev articles of 2024 This year’s most popular topics include Kafka data storage and migration, API management,…

The first installment in this series provided a brief introduction to the Cluster Observability Operator (COO). This article serves as a detailed guide for configuring alerts within the COO namespace. In the following sections, I will present specific examples for two structural configurations within the COO monitoring stack. Case 1: One monitoring stack for multiple…

This article will show you how to automatically issue certificates using Identity Management in Red Hat Enterprise Linux (IdM) and cert-manager operator for OpenShift. Securing communications is a must, not only to protect the data but to provide greater data integrity as well. Applications achieve greater communications security using cryptographic certificates, but these certificates have their own…

Network optimization with Data Plane Development Kit (DPDK) and Single Root Input/Output Virtualization (SR-IOV) is widely supported and adopted in Kubernetes and Red Hat OpenShift. In this article, we will present a means of automatically deploying an open source Cloud-Native Network Function (CNF), called Example-CNF, in order to test particular Telco-related configurations and scenarios, leveraging DPDK’s capabilities…
