Dispel See Cloud security

Recent cloud security topics are hot, but many colleagues don't know what cloud security is all about. This article attempts to work with colleagues on the topic of cloud security. Mention cloud security, not to mention cloud. So what is a cloud?

The Horse of God is a cloud

The skies are clear and cloudless, which means a fine day for us. However, for a leader in the field of information security, there must be another concept of "cloud" in our minds. Because in the computer field, "Cloud" is a number of self maintenance and management of virtual computing resources, usually for some large server clusters, including computing servers, storage servers, broadband resources and so on.

It is called "the cloud" because in some ways the cloud has many features of the cloud in reality:

1, clouds are generally larger

2, the size of the cloud can be dynamically scalable

3, clouds in the air erratic, can not and need not determine its specific location, but it does exist somewhere

4, the cloud boundary is vague, elusive, as the saying goes, "Who knows which cloud rain."

Second, God Horse is cloud computing

Mention cloud, cannot mention cloud computing. So what is cloud computing?

To better understand and comprehend cloud computing, many experts and scholars try to define cloud computing in different ways from different perspectives.

Cloud computing is based on virtualization technology, the network as the carrier to provide infrastructure, platform, software and other services as a form of integration of large-scale scalable computing, storage, data, applications and other distributed computing resources for collaborative work of the Super computing model. As a new Internet application model, cloud computing will become the leading way for people to obtain service and information in the future.

Three, the cloud terminal is coming

In cloud computing mode, users no longer need to buy complex hardware and software, such as using the cloud to work without having to install Office, and only need office in the cloud. Since the use of the cloud, our PC can not install a lot of things, then the PC will be lightweight development. Personal PC is called terminal, then Next generation PC is called "Cloud terminal", it no longer need CPU, hard disk, video card, even operating system and application software, because all these functions are done by public cloud server. "Cloud computing" will change the current computer "chassis + Monitor" mode, the future cloud terminal is only a small set-top box, or directly built into the display, low price, compared with the traditional PC system: Purchase Cloud Terminal system will save a lot of input. At the same time, it can be foreseen that in the IT operation dimension, it will reduce the cost burden of 90%;

Four, God horse is the cloud security

Now that we know what clouds and cloud computing are, we can well understand cloud security.

One of the important values of cloud computing is the need to expand the demand for hardware and software, but completely out of the local computing, data resources of cloud computing is a relatively ideal state. Given the private cloud, legacy systems, reliability, security and other factors, cloud computing currently has only the special significance of consolidating resources. Here we explain:

1. Private cloud is the cloud that is built for a company to use alone, so it can have advantages in stability, security and controllability.

2. Legacy system is a system that has been running for a long time and is very important to the organization, but often does not know how to deal with the large software system.

Cloud security arises because of the following concerns about cloud computing:

1. Security issues. While sharing is a good internet spirit, it is somewhat related to the security of information (confidentiality, integrity, usability). It is easy to understand that the cloud is shared and there is a natural security problem.

2. Trust. The physical side of the cloud, we are invisible. Can't see, can't touch, can we rest assured? This is a problem.
