" Just save it to the cloud ! "

You ’ve heard this , credibly in the same sentence with some other objectionable tech buzzwords . Run out of space on your iPhone ? Buy some more space in the swarm ! Your mom ca n’t figure out how to email you exposure from her dog ’s birthday party ? Upload them to the cloud ! But , do you actually understand what exactly the cloud is , or how it work ? There ’s no shame – it ’s perplexing as hell .

To clear thing up , here ’s what you should know .

wtf is the cloud

Cole Saladino/Thrillist/Jennifer Bui

The cloud is not a physical object

First thing first : you could not reach out and refer " the swarm . " That ’s because it ’s not a physical physical object in space , not some mammoth hard drive in the sky , but rather an enormous meshing of distant host all around the world that we are all always saving and retrieving data to and from via our high - speeding cyberspace connexion . It represents a fairly fundamental computing concept – that the share-out of resource ultimately optimize overall performance . And while most of us have in all likelihood only start hearing the condition " cloud computing " within the last X , it was actuallycoined by Compaq engineersback in the ' XC .

It’s taken the storage burden off your devices

Back in the twenty-four hour period , if you need to save text file or photos , you had to save them to your computer ’s hard drive . That meant going through and trim your Napster subroutine library , eminent schooltime essays , and digital camera pics every once in a while to liberate up enough space in rescript to save something new . Or maybe you ’d burn them to a cadmium or offload the handsome stuff to an external grueling drive . Now , thanks to dramatic improvement in net speeds , you seldom have to save a thing to your machine . or else , we stash blank - go down on files in the cloud , and seamlessly rain cats and dogs mental object from it via services like Spotify , Netflix , Dropbox , and Google Drive . Content – whether it ’s your favorite television series , a hot new record album , your holiday picture , or that complex spreadsheet you ’ve been putting together for work – is still physically save , just on a host   somewhere else , ready for you to access it whenever you ’re on-line .

Tech companies make billions hosting content in the cloud

Rather than manoeuver their own servers severally , most of the web ’s most popular apps , service , and site ( include the one you ’re reading right now ) pay to have their traffic and data hosted remotely in the cloud , which is not only more efficient , but also protects against outages and costly downtime . These cloud - hosting services are a huge cash cow for technical school heavyweight like Amazon , Microsoft , and Google , all of which have the resources to operate vast electronic internet of datum centers filled with waiter they can charge third - party customers to use .

To give you an approximation of just how massive these venture are , Amazon ’s cloud - host armaloneis estimatedto maneuver some 2 million servers in confidential data centers around the world , and can single - handedly die hard enormous service such as Netflix ’s entire stream surgical operation . So really , your uninterruptedStranger Thingsbinge on Netflix was only potential thanks to Amazon .

We’re rapidly running out of cloud storage space

Although the self-aggrandising swarm memory board companies are mint money off of our storage needs ( hell , Apple ’s getting 99 cents a calendar month from most of uswho’ve hit our iCloud quotas),experts warnthat we ’re hurtling toward a world in which there wo n’t be enough blank in the swarm to stash all the data we ’re creating . Our power to bring forth monolithic amounts of data is far outpace how quickly we can build the servers to host it – just think about how much space a single photo taken ona top - snick smartphone cameratakes up these 24-hour interval .
