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.

  • Cloud Computing Simplified: the Thoughts on Cloud Way
    Front cover Cloud Computing Simplified: The Thoughts on Cloud Way A selection of posts published on the IBM Thoughts on Cloud blog IBM Thoughts on Cloud bloggers team RedBlook Abstract This IBM® RedBlook™ publication is a collection of selected posts published on the IBM Thoughts on Cloud (http://thoughtsoncloud.com) blog. Thoughts on Cloud is IBM’s official cloud blog, contributed by hundreds of cloud computing specialists worldwide from IBM and IBM Business Partners. Most of the authors have hands-on experience implementing cloud solutions for various industries. The goal of the blog is to provide readers with a forum to discuss and debate various cloud computing topics. Starting with the basic building blocks of cloud computing, we cover a wide range of cloud topics in this book. We do not go into details of specific cloud products on the market, so this book serves as a cloud primer for readers who are new to this exciting technology. If you are already familiar with the fundamentals of cloud computing and would like to explore more advanced cloud topics, you can still benefit from this book. Each section is independent of the others, so it is OK to skip the sections you are familiar with and go directly to the section you’d like to read first. This book has the following sections. After reading this book, you will have a good understanding of all these concepts. Fundamentals of cloud computing The promise of cloud: How cloud is reshaping our world Cloud taxonomy: Deployment and service models Going deeper into the cloud: Cloud computing internals, dynamic clouds and composable business Cloud and your career Considerations for moving to cloud Cloud and friends: DevOps, mobile, big data, patterns, software-defined environments, software-defined networking and Internet of Things A brief look at the Cloud Open Standards and IBM Cloud Offerings What lies ahead for the future of cloud? © Copyright IBM Corp.
