 ### Cloud Computing and Storage
 
-- [The cloudyr project](https://cloudyr.github.io/) aims to provide interfaces to popular
-  Amazon, Azure and Google cloud services without the need for external system dependencies.
-  Amazon Web Services is a popular, proprietary cloud service offering a
-  suite of computing, storage, and infrastructure tools.
-  `r pkg("aws.signature")` provides functionality for generating AWS API request signatures.
-- *Elastic Cloud Compute (EC2)* is a cloud computing service.
-  `r gcode("segue")` (not on CRAN) manages EC2 instances and S3 storage,
-  which includes a parallel version of `lapply()`
-  for the Elastic Map Reduce (EMR) engine called `emrlapply()`.
-  It uses Hadoop Streaming on Amazon's EMR in order to get simple parallel computation.
-- *DBREST*: `r ohat("RAmazonDBREST")` provides an interface to Amazon's Simple DB API.
-- `r pkg("paws")` is an interface to nearly all AWS APIs,
-  including compute, storage, databases, and machine learning.
-  It also requires no external system dependencies.
-- Azure and Microsoft 365 are Microsoft's cloud computing services.
-- The Azure platform provides Paas, SaaS and IaaS and supports many different tools and frameworks,
-  including both Microsoft-specific and third-party systems;
-  while Microsoft 365 is a unified framework for accessing cloud data from
-  Microsoft's Office services, Windows and Dynamics.
-  The [AzureR package family](https://github.com/Azure/AzureR)
-  aims to provide a suite of lightweight, powerful tools for working with Azure in R.
-  The packages listed below are part of the family, and are also mirrored at the cloudyr project.
