For example, E-learning, cloud computing, social networking, virtual laboratories, virtual realities, virtual worlds, massive open online courses (MOOCs), and bring your own device (BYOD) are all new concepts of immersive and global education that have emerged in educational literature. One of the greatest challenges presented to e-learning solutions is the reproduction of the benefits of an educational institution’s physical laboratory. For a university without a computing lab, to obtain hands-on IT training with software, operating systems, networks, servers, storage, and cloud computing similar to that which could be received on a university campus computing lab, it is necessary to use a combination of technological tools. Such teaching tools must promote the transmission of knowledge, encourage interaction and collaboration, and ensure students obtain valuable hands-on experience.

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.
