Cloud-Services: Privater Cloud-Speicher im Überblick

Provider of cloud services are booming and enjoy a high demand. I would like to briefly describe how these cloud services work and which providers currently available on the market, but rather I will go to the private use of these services and describe especially the now very popular cloud storage closer.

How does cloud storage work

Funktionsweise der Cloud
Funktionsweise der Cloud

The data is stored centrally on the cloud server and the registered devices such as PC, laptop, tablet or smartphone using this information synchronized. Changes to documents either directly via a web browser in the cloud or on a terminal, these changes are applied to all devices used which ensures consistent data. Also you are in the event of data loss optimally protected.

Why cloud storage?

A key for storage in the cloud is the storage of personal information and documents. By saving on the servers of a provider you are as protected in the event of data loss (broken PC, laptop stolen, etc.), and can at any time access to the data. Similarly, all used devices such as PC, laptop and smartphone are synchronized with the service and you have all devices on the same data, one adds or deletes documents to which, it will propagate to all devices.

Prior to the use of a service for cloud storage, you should pay attention to some things, this includes especially the data security. Since the password is stored in most services directly from the provider, these also have access to this information and can therefore also necessary to reset the forgotten password. For example, even government organizations on request in certain cases to get access to the data, even if annoying user and account data will be lost with the supplier as a few years ago, for example, happens with Dropbox. However, my personal favorite Wuala, a Swiss provider of online storage is where the data is encrypted on the client side and the password never leaves your own computer, it can also be the forgotten password also will no longer reset and in these cases is no access to the account longer possible.

The most important providers for private cloud storage

Meanwhile, every major software vendor has a solution for online storage. These range from Google, Microsoft, Amazon, Salesforce, Telekom to specific storage providers such as Dropbox or Wuala. The services work similar in principle and in addition to the online storage, programs and clients for various operating systems and apps for iPhone, Android and BlackBerry devices. Most offer some storage for free, if this is not enough (usually relatively cheap) storage can be further extended with costs.

Cloud storage encryption – how to save your data

Storing data in the cloud is unencrypted, in most cases, which means that people who access the online stores have this view, change, or delete it. Some providers such as Wuala cloud or offer of safe house already an encryption on if someone gets access to the memory unjustified so he can see only cryptic content and do anything with the data. For other providers, the files will be encrypted before being transmitted to the cloud, but there again stored unencrypted and can be viewed by strangers (by authorized or unauthorized access).

Part of my next posts this week, until then, I ask for your patience as this will work closely with the encryption;-)
