One of the most well-known differences between managing UNIX-like systems and Windows systems is the Windows Registry. Chef has resources for creating, modifying, and deleting Windows Registry keys. Beware that these operations are nonreversible (there is no implicit backup of values, so it may be worth preparing a backup before modifying values), and that they can potentially … read the rest
A large number of managed systems require configuration of software that is outside the scope of the built-in Windows roles and features. Chef has a very handy resource for installing arbitrary software onto a Windows host through the windows_package resource, which behaves somewhat like the Linux-based package resource only for Windows-specific installations. The windows_package resource is capable of installing software … read the rest
Similar to Linux script resources for bash, ruby, and so on, Chef can execute arbitrarily-defined Windows batch scripts through the command interpreter. When these resources are used, Chef compiles the contents of the batch script as defined in the resource block’s code attribute and then deposits it on the managed host and it is executed from there.

While using Chef for Windows, there are multiple backends for the Windows feature resource—DISM and servermanagercmd. Each one has a specific Ruby class that will be used based on the determined backend as follows:
Similar to how Linux distributions have package management tools and a repository of packages, Windows has long had built-in packages that come with the OS. Both desktop and server releases of Windows have installable components out of the box, with servers having more than desktops.
In Windows parlance, roles are similar to Chef’s notion of roles—a collection of software packages … read the rest

Chef and Microsoft Windows are getting very popular. As chef practitioner, you must learn how chef works on Microsoft Windows. As you know that the client-side components of Chef are written in Ruby. Ruby is a cross-platform by nature, thus support for Windows is as straightforward as support for Linux and UNIX-like systems. It has been around for quite some … read the rest
Apache Spark is an exciting technology that is rapidly superseding Hadoop’s MapReduce as the preferred big data processing platform. Hadoop is an open source, distributed, Java computation framework consisting of the Hadoop Distributed File System (HDFS) and MapReduce, its execution engine. Spark is similar to Hadoop in that it’s a distributed, general-purpose computing platform. But Spark’s unique design, which allows for … read the rest
