Does the Fourth Amendment cover 'the cloud'?

Article IV, section 2: The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

This article is about one of the biggest issues facing individuals and corporations choosing to adopt public cloud computing or any other internet service. Many computers used for personal and business use are not being protected from being searched by the government without your permission.Over the last decade, courts adjudicated whether the government can access evidence of illegal activity stored on digital technology without violating the Fourth Amendment. 

I think that any computers should not be checked without the owners permission. I say this because I use computers all the time and would not want anyone to search through the things on my computer without first asking me.
