Description

This IDC PlanScape explores the common approaches to application modernization that prepare organizations against impending risks and allow them to adapt to emerging technologies. Application modernization is no longer a choice but a necessity for organizations aiming to reduce risks, improve efficiency, and maintain competitive positioning. By embracing cloud technologies and modern development practices, CIOs can transform legacy applications into strategic assets that drive long-term value for their organizations.According to Gerald Johnston, adjunct research advisor with IDC’s IT Executive Programs (IEP), “Application modernization is not just about migrating to the cloud; it’s about strategically transforming legacy systems to unlock scalability, agility, and innovation. Whether through re-factoring, rewriting, or rehosting, the ultimate goal is to align IT capabilities with evolving business demands while future proofing for emerging technologies.”

How Do Licenses Work?

How Do Licenses Work?

The primary function of a report license is to define how many people within a company are authorized to use the purchased report. This is separate to how a report might be delivered. Unless specifically identified otherwise, the purchase option is Single User. Below is a helpful description of that license, along with a sampling of others most commonly offered.

  • This license allows only one user to have access to and to use/read the report. It is not one user at a time or one user group; it is an individual who will be reading and utilizing the report.

  • This license allows for the entire purchasing company to read and use the report. This is the license level that would allow for a report to be placed on an internal company shared drive for access by all employees of that direct company. This license does not extend to parent or sister company use.

  • This license is designed to allow an entire department within a company full access to a report. The departmental license is a great option for companies that have more than one location and the department is spread out all over the country/world

  • This license is for companies that have one location where they want the report to be accessible by all employees within that physical location.

  • This is the most flexible of the licensing options. Some publishers will allow you to get a license for a preset number of people (typically 5). These licenses are ideal for small work groups.

License options are at the discretion of each publisher. As such, not all licenses indicated above are available for every product. If you are uncertain of the best license for your needs or would like a license that is not proactively available, please contact us and we will be happy to assist.
