The spin-off is to sharpen its focus on high-margin open hybrid cloud platform and artificial intelligence (AI) capabilities. Subsequently, on October 10, 2020, based on media articles, it is noted that the Indian operations, which are currently carried on under IBM India Private Limited (IBM India), would be restructured as well and around one-fourth of its employees will be part of the new entity catering to the needs of managed IT infrastructure services. Impact of the Material Event IBM India is one of the key global delivery centres for IBM Corporation with over 70% of its revenues being derived from export of services to the parent entity and its fellow subsidiaries, as part of the outsourcing business model. The company derives over 20% of its revenues from technology services, cloud platform and global business services division, wherein IBM India provides infrastructure services and technology support services to its clients.

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.

Now more than ever, organizations must evaluate their current and future data storage needs to find solutions that align with business goals. While cloud databases are relatively new to the scene, they show tremendous prospect in securing and managing data. In selecting our topic for this Trend Report, we found the amount of promise and advancement in the space to be unparalleled. This report highlights DZone’s original research on cloud databases and contributions from the community, as well as introduces new offerings within DZone Trend Reports. While you may know her as your friendly Java Zone copy editor, Lindsay Smith has stepped into the role of DZone’s Publications Content Manager. Among many new endeavors, she’s spearheading our new strategy for Executive Insights — a series we’ve titled, “Leaders in Tech,” which serves to complement our original research. The series focuses on the viewpoints of industry frontrunners, tech evangelists, and DZone members who share their insights into research findings and outlooks for the future.
