Cloud storage is a great and simple way for storing large amounts of data without taking up storage space. It can also be a good way of sharing files to improve collaboration within a team. Cloud storage not only makes file sharing easier, but also automatically updates devices in the network, and reduces the reliance on costly hardware and infrastructure.

Cloud storage and file-sharing and syncing services provide seamless access to all your important data, from any location. For business settings, your software and other apps are then able to retrieve or access your files, so using a service that implements easy integration is crucial. Many cloud-based storage focuses on a specific area, such as security or keeping one synced folder on every device, but others are generalists, and even double as co-editing software. All service should also provide online file backups as a matter of course.

The key elements to look at when choosing a cloud storage provider include financial stability, proven infrastructure, established customer base, geographically distributed data centers, security and encryption, third-party validation, and service level agreement (SLA) terms and execution. Essentially, cloud storage should efficiently simplify and make portable your established workflows, while maintaining the security of your data.

Google Drive is the easiest way to share information between myself and my coworkers. When I need to do work and I don't have my laptop with me, I can log into Google Drive and I'm able to access my work from anywhere. The best part about it Google Drive is that it's free as long as you have a Google account. Other users can also share work via the drive so that I can have what I need, when I need it.
