Three tips to ensure data security in cloud computing era

Silicon Valley Network message Jessica, this is a very good question! In many fields of science and technology, cloud computing is usually a fairly reliable technology. However, cloud computing server downtime still occurs. Just last week, Amazon's many services failed, and subsequently spread to Amazon's database, cloud services and flexible computing (elastic Compute) services, while causing many internet services using Amazon Cloud services to crash, including Instagram, Netflix, Consumer-oriented Internet services such as pocket and Pinterest.

Here, I offer you 3 small ways to make your information stored in the cloud more secure.

1. Backup Data

If you're storing important data in the cloud, make sure you have a backup locally, because the first rule of data storage is "always have more than one backup file," So "backup, backup, Backup" is a truth that never goes out of fashion.

In addition to real-time backup of important files, you also need to review these files regularly to ensure that their files are not corrupted, damaged, and that different backups need to be stored in different locations. Another advantage of this is that you can not only make sure that your files are safe when the accident occurs, but you can also upload files to another server at any time when a cloud server is paralyzed.

In general, backup--backup--tests.

2. Preparation

You never know when a cloud server you rely on will suddenly become paralyzed, whether it is a well-known bluehost in the industry or Amazon databases used by large companies such as Instagram. In the former US "Sandy" hurricane during the havoc, countless well-known sites were flooded in New York's data center was forced to line up, and even Amazon is located in the United States Virginia State mainly to support the Amazon Network services (Amazon web Services) have experienced paralysis in data centers that access traffic.

In the 2011, renowned websites such as HootSuite, Foursquare and Reddit have been paralysed for nearly 24 hours as a result of the failure of Amazon's network services data center.

Therefore, "precaution" usually helps users to reduce losses in the event of a disaster. Here we have to mention a small case of Amazon Network Service during the 2011-year failure, which is the well-known photo-sharing website SmugMug that has not been affected by this server paralysis.

At the time, the company did not rely solely on the services provided by the Amazon Data Center in Virginia, but instead distributed its data in many different locations (similar to the multiple-point backup in the previous section). The company then explained in detail its approach in a statement.

"If the information you store in the cloud is important, such as banking, government, healthcare, health care, and financial data, you need to deploy that information to the widest possible extent." This work is time-consuming and laborious, so it is unrealistic for many people. But this is important for some companies. It should be pointed out that such an approach may not really have its use, but it is enough to prevent it. The company wrote in its official blog.

3. Beyond the Clouds

If the budget allows, consider setting up a number of cloud services for yourself. For example, in addition to using Amazon Web services, you can also use Microsoft Azure or Rackspace cloud services.
