The Impact of Virtualization on Software Architecture

Virtualization has a profound impact on IT environments, as it abstracts the physical characteristics of computing resources from users. Virtualization techniques are mainly used for enhancing capacity (using excess computer resources efficiently), compatibility (running legacy applications on modern platforms), and manageability (easy patch management and deployment). However, one must not confuse virtualization technologies—such as OS virtualization and application virtualization—with virtualization itself. In principle, virtualization can be applied to provide an abstraction layer that helps solve complex problems in software architecture.

Implementing Parallelism With A SearchResultCollection

Implementing Parallel.ForEach with a SearchResultCollection: The below piece of code helps to check the given user is a part of the given active directory group. To implement Parallel.ForEach with a SearchResultCollection, do the casting with the SearchResult object and covert it into a list. //// Directory Searcher var directorySearcher = new DirectorySearcher(string.Format("(CN={0})", groupName)); //// Find group var searchResultCollection = directorySearcher.FindAll().Cast ().ToList(); Parallel.ForEach(searchResultCollection, searchResult => {  // enumerate members  var resultPropColl = searchResult.Properties;  Parallel.ForEach(resultPropColl["member"].Cast ().ToList(), member =>  {    var memberEntry = new DirectoryEntry("LDAP://" + member);    var userProperties = memberEntry.Properties;    if (GetUserNameFromProperties(userProperties, "sAMAccountName") == userName)    {      return true; ...
