A First Look at Windows and Mainframe Interoperability

Data centers continue to see an increase in the mix of mainframes and servers that support operational and line-of-business (LoB) applications. Not only that, but enterprises across the world, particularly Fortune 500 companies, still have a huge investment in legacy code running on mainframes (think CISC and IMS). Because this code may be running on mainframes for a long time to come, systems integrators and application programmers must be able to access those resources, and that requires integration. Simply put, integration with mainframes isn’t optional—it’s a must-have.

Standards and Microsoft Office: Why OOXML Matters

Traditionally, document formats were tethered to the authoring tool. But today information needs to be more fluid. Microsoft has been one company that has taken the initiative to open file formats, designing an interoperable document format named Office Open XML (OOXML). In this article, we discuss why OOXML is important not only to Microsoft, but also to the enterprise.

An Evolution

Talking the Talk: Windows, Linux, and B2B

Conversations about Windows and Linux integration aren’t all that uncommon these days, but typically they revolve around shared network resources and user accounts. However, that’s only a small part of integration: What’s also critical is that enterprise applications across platforms must be able to seamlessly, reliably, and securely communicate. This is an important aspect of integration because enterprises run mission-critical applications and services on Windows, Linux, UNIX, and mainframes. It’s simply not possible for an enterprise IT department to do things “one way”.

Make UNIX and Linux Speak AD

Active Directory (AD) is prevalent in most enterprises today, so it makes a lot of sense to leverage it to support your UNIX and Linux systems (in this article, I use the term “UNIX” to mean any UNIX flavor or Linux). One obvious benefit of this approach is the ability to consolidate your user provisioning and access management to a single directory, rather than trying to individually provision users and access rights for independent Windows, UNIX, and Linux networks. This quickly translates into increased security and reduced cost.
