Thinking of solving cloud computing security problem

Characteristics of cloud computing application environment

Many people talk about cloud computing, always in good faith to ignore the internal data center itself in the security of a lot of deficiencies, but assume that if the application and data in the enterprise internal data center is foolproof and very stable. In fact, we have a detailed comparison of cloud computing centers and enterprise data centers in the following four areas:

1. High Availability

In addition to the fact that some large enterprises use mainframes and very expensive high-availability solutions (such as IBM Power HA) to ensure that core applications reach five nine availability (that is, 5 minutes of downtime per year), the average enterprise data center is still poorly available in terms of high availability, Even very professional internet companies are also very difficult to be alone, such as the recent domestic large-scale video site has been a series of downtime phenomenon. In this regard, cloud computing centers are often reported, but by calculating actual downtime, most can achieve three nine (that is, 9 hours of downtime per year).

2. Data security aspects

I have read a report that has a very important data in this report, that is, enterprise data is stolen 60% of the situation is the enterprise insiders. In the computing center, the harm is limited by the fact that not only is there a certain set of security rules in place to prevent its system managers from contacting the stored enterprise data, but managers are not aware of the core data of the enterprise.

3. Although many non-it industry large enterprises are very good in terms of benefits, they rarely attract particularly good it engineers because of their lack of career planning and technology development for IT personnel. Cloud computing, because of its professionalism, can train the best engineers who will improve the operating level of the cloud Computing Center in all its aspects, including, of course, security.

4. Wide Area Network

For small and medium enterprises, most of the enterprise's IT services are accessible only through Ethernet. However, for large enterprises, because they have many branches, need to build VPN services on the WAN, so if there is a problem in the WAN, large enterprises will be affected, and the cloud computing center is inherently dependent on the WAN. The table summarizes the comparisons above. Overall, cloud computing centers are no less than the data centers of large enterprises, and far better than the data centers of small and medium-sized enterprises.
