Containerization is a key enabling technology for flexibly delivering workloads to private and public clouds and DevOps. Among their many benefits, containers allow legacy applications to run in almost any host environment without being rewritten – an enormous advantage for enterprises with numerous applications, each composed of thousands of lines of code. To facilitate deployment of containerized workloads and development of new cloud-native applications, companies large and small are modernizing around platforms such as Red Hat OpenShift. IBM has developed a series of middleware tools called IBM Cloud Pak solutions designed to enhance and extend the functionality and capabilities of Red Hat OpenShift. The solutions include Cloud Pak for Data, Business Automation, Watson AIOps, Integration, Network Application, and Security, and give enterprises the fully modular and easy-to- consume capabilities they need to bring the next 80% of their workloads into modern, cloud-based environments.

  • Research Fabric Computing Poised As a Preferred Infrastructure For
    Research Publication Date: 11 February 2011 ID Number: G00210438 Fabric Computing Poised as a Preferred Infrastructure for Virtualization and Cloud Computing George J. Weiss, Andrew Butler Fabric computing is a fixture on the radar screen of many IT groups, driven by the increased penetration of virtualization and prospects for cloud computing. As virtualization penetration increases, IT organizations will deploy virtual machine (VM) mobility, which will demand more attention to a fabric-based infrastructure that better integrates server, storage and networking for greater agility and faster time to deploy. Key Findings Fabric computing is nearing a stage of adolescence — maturing quickly, but with much room for growth and maturation. Enterprises with serious initiatives in virtualization and cloud computing need to begin designing a fabric-based infrastructure, and the organizational structure to properly support it, as the underlying foundation for these initiatives. Based on polling results and many interactions with clients, we believe that Cisco has been the most influential marketing force in expanding the IT vocabulary and recognition for fabric computing, which is currently dominated by two vendors (Cisco and HP), with Dell, IBM and others making moves. Most users are still determining the use cases of fabric-based computing, and, as yet, are unwilling to be sold prepackaged modules of complete solutions by a single vendor. Recommendations Put fabric computing on the priority list of data center architecture planning, if your virtualization plans call for a heavily dynamic infrastructure. Do not overhaul or plan on rip-and-replace fabric development, but impose on vendors' design guidelines that harmonize their solutions with your other data center infrastructure.

    IBM Service Management: Visibility. Control. Automation. Smarter service delivery for a smarter planet. Every day, the world is becoming more instrumented, interconnected, and intelligent. Infrastructures and assets across the globe are rapidly being digitized, turning physical assets into smart assets that allow people, systems, and objects to communicate and interact with each other in entirely new ways. This “smarter planet” is creating opportunities for new, smarter, differentiated services and products. Organizations that can rapidly adapt and innovate to meet or exceed customer expectations for new services and products will be in a position to accelerate growth and gain competitive edge. A more digitized world requires changes in the way we think Integrated service management: about, design, deliver, and manage business services and products.
