Traditionally, APIs are tethered to specific internet locations, typically tied to a fixed URL on a server or set of servers. Enterprises are increasingly moving away from that and developing their APIs in different languages and deploying them across diverse environments. The increase in demand for multi cloud deployments and distributed systems have made the concept of "locationless" resources increasingly significant. Locationless APIs are abstracted from specific physical locations, enabling interaction regardless of the underlying service's location. However, it is a complex challenge of ..read more

This is the first article in a two-part series that looks at the new features of C# 12. C# 12 is supported by the .NET 8 SDK, which was released in November 2023. The features described in this article are usable in everyday programs. In the second article, we’ll cover advanced features for specific use cases. Collection expressions Collection expressions are a new syntax to initialize a collection type. The syntax consists of square brackets ([, ]) that surround the collection items as shown in the following examples: // Initialize a variable int[] arrayOfInt = [1, 2, 3]; // Initialize an a ..read more

At Red Hat Summit 2023, we addressed the market demand for tools and services that help secure the software supply chain by announcing two projects that will change the way developers and ops develop and deploy their applications to Red Hat OpenShift. These projects are the Red Hat Trusted Application Pipeline and Red Hat Developer Hub. Meanwhile, with the help of customer feedback, these projects have matured into Red Hat products that are available for self-managed deployments and are part of a product family that addresses the software supply chain from end to end—Red Hat Trusted Software S ..read more

Tagging is a common feature offered today as part of system and platform management tools. Its goal is to provide a consistent way to organize, search and filter managed entities, thus improving reporting and overall operations management efficiency. A common challenge when dealing with different tools and platforms is the lack of tagging governance. Tags assignment and values can quickly run out of control unless best practices and rules are instored and honored in an organization. Often, organizations choose to define their taxonomy in a central configuration management database (CMDB) and u ..read more

This article is aimed at users who would like to integrate or monitor their Red Hat OpenShift cluster using the Datadog monitoring solution. We will use the Datadog Operator to instantiate our agent and collect all metrics, cluster and container/pod logs, network, CPU, and memory consumption. Prerequisites User with the cluster-admin cluster role OpenShift 4.12 or above Datadog account Procedure 1. Create the Datadog API key: To add a new Datadog API key, navigate to Organization Settings > API Keys. If you have the permission to create API keys, click New Key in the top r ..read more

As of Red Hat build of Keycloak 22, creating a highly available Keycloak solution can introduce operational complexity, as well as performance issues.  For example, to have multiple instances of Keycloak that share the same session information, a common cache that is available to all Keycloak instances is a must (in this case, Red Hat Data Grid common to two Red Hat OpenShift clusters) as well a common database (that is highly available and/or fault tolerant). Instead, this solution avoids a common cache or database and utilizes multiple single instances that all use the same source for u ..read more

In today's dynamic IT landscape, efficient management of server infrastructure is paramount. Regular patching is essential for maintaining security, stability, and compliance across enterprise environments. Red Hat Enterprise Linux (RHEL) servers are widely used in business-critical operations, making timely patching a crucial task. Manual patching can be time-consuming and error-prone, especially for large server deployments. In this technical blog, we'll explore how to streamline patch updates of SELinux on RHEL servers using Red Hat Ansible Automation Platform 2.4. Prerequisites This articl ..read more

As organizations grow, their software needs to evolve as well. Initially, a single team often handles end-to-end development of a monolithic application. However, as successful products expand, complexity increases with multiple teams, stakeholders, and integrations. Decision-making becomes slower, requiring extensive agreement. As development teams adapt to these demands, aligning architecture with the team structure becomes crucial. A hybrid cloud microservices architecture becomes invaluable. A hybrid cloud environment combines on-premise servers with cloud services, allowing independent de ..read more

Event-Driven Ansible is an open source developer preview designed to flexibly enable teams to create event-driven automation scenarios across various IT domains (network, DevOps, security, CloudOps, infrastructure, and more). This article aims to teach you how to install the ansible-rulebook command-line interface (CLI) tools and use them when executing the rulebooks. Our rulebook will be used to create a conditional event, so whenever that event occurs, it will trigger and execute the playbook that we defined in action. This is the first step to event-driven development. ansible-rul ..read more

Automation has become a key factor in streamlining operations, reducing human errors, and improving overall efficiency. One popular tool that has revolutionized automation is Red Hat Ansible Automation Platform, an enterprise automation platform. Ansible's versatility and ease of use make it a great choice for managing complex IT infrastructure. In this article, we'll explore different types of nodes, peering relationships, and how Ansible controllers orchestrate the nodes as part of an automation mesh. Automation mesh Automation mesh is a key component of Ansible Automation Platform that enab ..read more
