Expert: How to solve the problem of cloud computing service interruption?

Cloud computing solutions allow businesses to be flexible and efficient when dealing with their business, but they can also put companies in some situations where a prolonged disruption of cloud computing services may even cause a business to collapse.

While cloud service providers are unlikely to experience severe cloud service outages, it is clear that this is something that does happen. For example, the 2010 http://www.aliyun.com/zixun/aggregation/14358.html "> Amazon Web Service had a four-day cloud outage and some users were completely unable to use the service. Such failures are bogged down by businesses that rely heavily on cloud computing services.

Fortunately, users can take steps to ensure that important applications are not disturbed by cloud outages. Here are some of the steps you can take:

1. Make good use of the choices provided by cloud computing service providers

Some cloud computing service providers offer multiple areas of availability. As a result, users can place specific solutions in different areas, and each zone will not be affected by failure. In fact, taking this approach usually leads to a cloud service premium, but it is worthwhile for many important applications.

2. Consider multiple cloud computing service providers

To secure critical applications, users need to build a schema that includes multiple providers. To do this, users will need to do some research because in fact some cloud computing service providers may share data center resources. It is worth noting, however, that if the provider relies on the same area to provide services to the user, it is not a good thing for the user to have multiple providers.

3. Incorporate availability levels into service level agreements (SLAs)

Whenever possible, users need to ensure that their service level agreements include results that occur after a service outage. Determine an acceptable level of availability for a given cloud application. For example, users may need 99.999% availability if they need a troubleshooting service provided by a cloud computing service provider.

4, repeatedly consider whether some cloud applications should be put into the cloud

If users are unwilling to take risks and are unwilling to ensure application availability as required or to address cloud outages, users are likely to handle the public cloud solution poorly. This is not to say that cloud solutions do not meet the needs of users, but that users need to be cautious and ready to take on the risks involved. (Compile/Lin Xuan, say)
