The cloud ERA requires more advanced business continuity and data protection

The advantage of cloud computing is the optimization of resources and http://www.aliyun.com/zixun/aggregation/13543.html "the convenience of >it service, under the premise of reducing it cost, How to ensure the continuity of business operations and the security of core data has always been the most important. On the premise of universal application of virtualization, how to combine the mainstream virtualization technology to protect the system and data in the existing virtualization architecture. Many users have used VMware for server virtualization and the implementation of the unified storage of data, people familiar with VMware technology know that VMware virtual machines are generally stored in the form of files in the background storage, in this case how to protect the corresponding contact data? When the virtual machine fails, how to quickly restore the background disk array failure? To ensure continuity of the business, has become a new generation of data centers facing problems, Fei Kang Advanced Continuous data protection technology is to adapt to the above requirements, not only provide the core data protection, but also can protect the scope of the operating system to cover the protection, which is the perfect combination of virtualization computing. The continuous data protection technology is not only a disaster backup technology that protects the latest data when the cloud platform disaster occurs, but also a backup technology that restores the original data when the historical data is lost, because the data is saved at multiple points of time automatically, so even if the lost data has been passed for several days, You can still easily achieve the ability to get the right historical data in 1 minutes. For the cloud environment, host backup is really server-free backup way.

From a business deployment approach, a business can choose to use a service provider's cloud or build its own private cloud. Many large enterprises understand the economic benefits of cloud computing, but want to ensure that security policies are strictly enforced. Therefore, the first consideration is the "private cloud", which can increase the economic benefits of the resource pool and standardize its development, deployment, and management. It is also a matter for enterprises to consider how to communicate with each other "private cloud" in time, and how to efficiently complete offsite backup and disaster-tolerance of data between private cloud.

A complete cloud data platform for disaster tolerance, should not only consider switching (failover-from one cloud to another), you should also consider the failback (failback) problem. In general, the cloud Platform production environment in disaster recovery needs to adopt a failback approach, and failback involves more technical points than is switching, so the current market most of the disaster preparedness technology does not have the ability to failback. The company's CDP continuous data protection technology is different, its replication technology provided by the "reverse" power can easily achieve failback after the failure, the data of the disaster preparation cloud synchronization back to production cloud environment, and the drift between the cloud only need to click on the console "reverse" can be completed, simple and convenient.

In addition, in order to ensure the data consistency between cloud production and disaster preparation cloud in cloud environment, the replication technology of Fei Kang Company also provides the consistency contrast mechanism of disk system at both ends of the cloud platform, which can be used to compare the disk block level between the production cloud and the disaster preparation cloud. This technology can be in the production cloud environment and disaster preparedness cloud environment data inconsistency with the rapid completion of Datum point synchronization, the scan difference technology is used to ensure the consistency of data between different cloud platforms, and only when the data between production cloud and disaster preparation cloud is identical can the free drift between different clouds be ensured.

For cloud platforms, replication technologies between different cloud platforms should have a variety of options and adjustments. Let's take a look at what the company has to deal with cloud data drift in different cloud environments: 1. Replication cdr;2 based on continuous IO. A specific time of day. such as: At 12:00 every night to start copying; 3. The duration interval. such as: Copy every 10 minutes, 4. According to the volume change. For example, when new data exceeds 5MB, replication begins. These strategies can be used individually or in combination, providing a very flexible policy triggering mechanism for administrators.

With the continuous expansion of the cloud platform, the transition from private cloud to public cloud is an inevitable trend of cloud platform development, but the transmission bandwidth occupied by data movement between cloud platforms is also a problem that has to be considered and faced. Also mentioned here are Fei Kang's microscan simple data transmission technology. This technology allows data to replicate between different cloud platforms through a variety of connection links, such as SDH, ADSL, T1, T3, E1, E3, F.R, FC, etc. Unlimited distance between local and remote cloud storage pools, can be spanned, across cities, across provinces, and across regions, and the link bandwidth can be flexibly selected according to the increment of data, the input cost can be measured and controlled, and its transmission bandwidth is only the 1/10-1/20 of traditional storage bandwidth, and the cost of investment is minimized. Get the maximum ROI.
