** The local device must possess a duplicated fraction of the [[World Wide Web]] (WWW) or a modified copy of that fraction to satisfy the independence feature. Because this fraction synchronizes with the web, it satisfies the collaboration feature of dew computing.<ref name=":0" />

* Storage in Dew (SiD)

** The [[Storage (memory)|storage]] of the local device is partially or fully copied into the cloud. An example of this is [[Dropbox (service)|Dropbox]], in which a user can create a folder in the cloud, and have access to the folder and its contents on the local device once the synchronization is completedcomplete. Since the user can access the files at any time without the need for constant [[Internet access]], this category meets the independence feature of dew computing. SiD also meets the collaboration feature because the folder and its contents automatically synchronize with the cloud service.<ref name=":0" />

* Database in Dew (DBiD)

** The local device and the cloud both store copies of the same [[database]]. One of these two databases is considered the main version and can be defined as such by the [[database administrator]]. This service increases the reliability of a database, since one of the databases can act as the [[backup]] for the other.<ref name=":0" />

* Software in Dew (SiD)

** The configuration and ownership of software are saved in the [[Cloud computing|cloud]]. Good examplesExamples of this are the [[Apple App Store]] and [[Google Play]], where the applications that the user installs are saved to their account and can then be installed on any device linked to that user's account.<ref name=":0" />

* Platform in Dew (PiD)

** A software development suite must be installed on the local device with the settings and application data synchronized to the cloud service. A [[Software development kit|Software Development Kit]] on its own does not satisfy these requirements; it must be able to synchronize development data, system deployment data, and online backups. An example of this category is GitHub.<ref name=":0" />

* Infrastructure as Dew (IaD)

** The local device is dynamically supported by cloud services. IaD can come in different forms, but the following two forms can be used: (1) the local device can have an exact duplicate DVM instance in the cloud, which is always kept in the same state as the local instance, or (2) the local device can have all its settings/data saved in the cloud, including system settings/data and data for each application.<ref name=":0" />

* Data in Dew (DiD)

** The term DiD is applied when all its applications satisfy the independence and collaboration requirements but cannot be placed in any of the above categories. An example of this is the [[GroupWise|Novell Groupwise]] email client.<ref name=":0" />
