Discover what is considered to be cloud storage, the different types of cloud storage and storage providers, and why people or businesses might choose this over traditional local storage.
- [Instructor] Well, let's take some time now in this chapter to focus on cloud storage. When we look at the name cloud storage, it suggests exactly what you might think, storing your data with a cloud storage service provider, instead of keeping that data on a local system. To get at your data stored on the cloud, you use an internet connection. Let's take a look at the advantages of cloud storage over the traditional storage techniques. First of all, you can get at your data from anywhere, as long as you have an internet connection.
This is appealing to road warriors who can use any computer or mobile device, and there's no need to carry around physical storage devices, like external hard drives when they need to be mobile. And if your business has multiple branch offices, they can all get access to the same data stored on the cloud. There's a wide variety of storage service providers and a wide range of services they provide. Some allow storage of many types of data, while others are more specific, allowing you to store one type of data, like email or photos.
Think of Flickr and Photobucket, for example, where you can store your photos and share them with anyone you want, or check out mail.com if you're interested in safely storing or archiving your email messages, which can pile up very quickly, by the way. Some storage providers are small, while others can be huge. Google, for example, has many data centers, many of which are the size of a football field, containing thousands of individual servers. So really, in simple terms, a cloud storage system is at least one data server that's connected to the internet.
Subscribers can copy files to the data server and access those files to copy them back, or even manipulate them directly on the server. Between the subscribing device and the data server is a web-based interface the subscriber uses to log in and access their data. Now the more storage space needed, the more hard drives the service provider can add to the system to increase capacity. In reality, cloud storage systems will consist of dozens or even hundreds of data servers and the data will be stored in more than one area.
This redundancy is what makes cloud storage safe, reliable, and assures clients they'll be able to access their data at any time. The main reason businesses use cloud storage is for safety. Not necessarily because they don't have the space. If the whole office goes up in flames, they need not worry about their precious data, stored safely on the cloud. And also important to businesses is the cost savings. Storage space is simply rented from a cloud storage provider using either a cost per gigabyte stored model or a cost per data transferred model.
There's no need to buy your own infrastructure, pay to keep it running, pay to keep it cool, nor pay someone to maintain it. That's all handled by the service provider.
David also presents an overview of migration steps for your consideration, as you contemplate a move to the cloud, and reviews common cloud technologies including Google and G Suite, Microsoft Office 365, and OneDrive. He goes into cloud tools for teams, including Dropbox, Google Docs, and Asana. To wrap up, he outlines how to evaluate the ongoing effectiveness of the cloud for your business.
