Into the CloudPosted by Michael Patrick in Cloud, Introductions, News, SoftLayer
You’ll see the word “cloud” bouncing around quite a bit in IT nowadays. If you have been following The Inner Layer you’ll have seen it a few times here as well. A cloud service is just something that is hosted on the Internet. Typically in a cloud scenario you are not actually doing the hosting but rather using hosted resources someone else is providing. Usually you’ll hear it in terms of computing and storage.
This is going to be a brief article on a cloud storage product we are doing here at SoftLayer called CloudLayer™ Storage.
CloudLayer™ Storage is a WebDAV based system which uses client software on the local machine in order to redirect filesystem operations to the storage repository here at SoftLayer. In Windows you end up with a drive letter; on a Unix system you end up with a mount point. In both cases when you create folders and save files on those locations the actions actually happen on our storage repository here. Because the files are located with us you are able to access them wherever you are. Through the CloudLayer™ web UI you’re able to also set up files for sharing with others so even if where you are never changes there is still value to using the cloud storage.
Even using a cloud storage system you must maintain proper backups. Hardware, software and human error all happens. Tied in with that concept of “errors happen” … if you have files on CloudLayer™ that you need for a presentation, download them ahead of time. You don’t want to be caught without files simply because the Internet connection at your hotel decided to take a nap the morning of your event.
Now what of security? Well, the connection to the CloudLayer™ endpoint here at SoftLayer is done via an encrypted session so people cannot snoop on your transmissions. This does mean you need to allow 443/tcp outbound communications via your firewall but since that is the normal HTTPS port I’d imagine you already have it open. Within CloudLayer™ you can control with whom you share your files.
Since CloudLayer™ is a filesystem redirected over the Internet the performance you get will be dependent on your local connection speed. Its best to treat CloudLayer™ Storage as simply a file repository. If you find you need some kind of off-machine storage for running applications on your server you could look into our iSCSI product.
So, dear readers, go forth and have a cloudy day.
