All of you would have a basic understanding of cloud computing. However, do you know what role cloud computing plays in disaster recovery and business continuity? Next, let’s see an introduction.
The most fundamental role may be remote data backup. Cloud computing provides users with some remote storage as well as on-line data storage. Moreover, disaster recovery can be realized from cloud computing much more quickly than from tape backup.
Cloud computing allows client server failover. Currently, cloud computing makes it quite convenient to copy data and deal with failures for Wintel server, so users should backup enterprise data apart from copying data. With backup, users can recover a single file to a certain point. If users just copy data of server, failures may emerge, making the enterprise fail to restore to the previous state.
To summarize, cloud computing provides enterprise with both data backup and server failover. Furthermore, there is a secondary center which is remote enough and allows disaster recovery.
Apart from roles mentioned above, cloud computing can also make it possible to realize business continuity. As we know, enterprises’ business continuity planning often gets lost in a disaster, and all these plans are of great concern. If lost plans were originally stored in main center system and users are unable to enter the system, how can they perform system recovery? Cloud computing makes it possible to access these plans, and users can visit cloud from their notebook computer anywhere so as to inform server script. For business continuity managers, cloud computing must be one of key factors to success.
Large scale enterprises pay much attention to business continuity and own all-sided planning. For small and medium enterprises which need to deal with lots of issues, can cloud computing provide them enough advantages? As a matter of fact, cloud computing can casino online provide small and medium enterprise with the same functions as those provided for large scale enterprises. Many large scale enterprises own secondary data center, so they can use it to perform data backup and disaster recovery. Nevertheless, most small and medium enterprises do not have secondary data center. For small enterprises which just own servers from 25 to 100, they often backup data to a tape. They may store the tape in local and do not have complex disaster recovery planning and strategies. Nowadays, cloud computing offers them the same functions as those offered in large scale enterprises. They can backup data or copy server to a remote site, making it possible to transfer failures to the remote site.
Is there a situation where cloud computing does not make any sense?
The answer is definitely yes. Sometimes, cloud computing does not have any sense for enterprises. For instance, high transaction apps will not work in cloud computing well or even fail to work. But for data backup, cloud computing is of great significance, because what your enterprise should do is backup data and recover lost data.
In the future, we believe more and more users would turn to cloud computing. With the increase of cloud services, cloud-based disaster recovery can be a feasible alternative solution for lots of clients.
