Some companies are now focusing on the Internet and cloud computing with global coverage, in order to provide a new type of disaster relief-a company provides services to another company in the affected area to help the latter's business processes run normally.
In a cloud operating environment, multiple copies of the data set are created and kept in sync. For Cassandra, MongoDB and other major data processing systems, 3 is a mysterious number. Cloud storage company Nirvanix said that if the customer's data is stored in its third node (Node 3) data center in Japan, it will transfer the copy to another continent.
Scott Genereaux, CEO of Nirvanix, said: "If our customers are eager to transfer data from Japan, we will ensure that the data is migrated smoothly and in a timely manner, without disrupting the customers' business operations." Provided, customers can choose to migrate data to data centers located in New York, Los Angeles, Dallas or Frankfurt, Germany.
This proposal is only a precautionary measure, because Nirvanix expects that its data center in Japan will continue to operate. The data center is 200 miles away from the northern part of Honshu affected by the tsunami. However, considering that Japanese power companies have imposed power outages in turn, some customers may still consider this proposal. Whether the Japanese authorities are capable of controlling the nuclear disaster that the Fukushima Daiichi nuclear power plant may face is still unknown.
David Vellente is the co-founder of Wikibon.org, a professional IT community website. Members of the community website can enjoy free solutions to problems. He said that a company that provides free services to another company in an area affected by natural disasters may become a new type of international assistance. He said: "In such extraordinary times, we need to provide money, assistance and resources. This gesture made by Nirvanix shows that enterprises should help other enterprises in need during difficult times." Cloud computing methods make this type of assistance more than It used to be much more feasible.
In addition to data protection, the condition of the submarine cable in the earthquake zone is still worrying. Kei Furuta, CEO of Equinix Tokyo, a hosting facility provider, said: "We know that the submarine communications infrastructure has been damaged; we are happy to provide our assistance for the restoration and reconstruction work."
Equinix is ​​willing to build a virtual local area network (VLAN) through its switching architecture, so that service providers with backup facilities can establish two-way VLANs through their two hosting facilities in Tokyo (which have not been affected by this disaster). connection. If the request letter is sent to inix.com, this service will be provided free of charge. An Amazon spokesperson acknowledged that although Amazon Web Services did not publicly signal proactive assistance, it privately told members of its Japanese user organization JAWS-UG that its resources are readily available.
It is reported that Amazon Web Services stated that it would guarantee free and scalable computing power to the Red Cross organization in order to publish relevant information; and to the Red Cross and the Southwest Conference to temporarily save Japan (Save Japan) The foundation provides free and scalable computing power, designed to collect donations. An Amazon spokesperson declined to comment, saying the company did not want to show its head because of the disaster. Coincidentally, it announced that it had opened data centers in the Tokyo area in early March of this year; a company spokesperson confirmed that these data centers are still operating normally. This area has become the fifth largest data center concentration area for Amazon Elastic Compute Cloud (EC2), second only to Amazon US East Data Center in Northern Virginia, Amazon US West Data Center in Washington State, European Data Center in Dublin, Ireland, and Singapore An existing Asian data center.
If anyone wants to know whether the data center in the Asia-Pacific region is operating normally, just check the Amazon Service Health Dashboard to understand the situation.
In some cases, virtual machines or virtual machine images of existing workloads can be built in enterprise data centers and stored in cloud data centers. In the event of an enterprise data center failure, the virtual machine can act as a recovery mechanism and can be reactivated in the cloud.
Indu Kodukula, a well-known IT service company SunGard, said at the Cloud Connect conference in 2011 that 90% of SunGard customers are now using, or at least trying to reactivate virtual machines at remote sites as a disaster recovery mechanism. Previous disaster recovery included the need to install almost the same hardware in different places, as well as the same series of software. It is difficult to keep the two sites in sync, and it is more difficult to perform a full set of tests on the system, because it means that the production system needs to be shut down, hoping that they can be reactivated soon after the recovery site.
Kodukula said: "Each of our customers is running (testing) at least one production system in the cloud." Right now, this means that SunGard's data center facilities are running VMware ESX Server virtual machines. In the future, this approach will be popularized among all virtual machine users, and customers can use the different cloud data center facilities of their choice.
It is also worth mentioning that Telehouse America, a managed IT service provider in the United States and Japan, said that its 21 data centers in Japan (including the Sendai data center in the tsunami-affected area) are operating normally. When their data center received an order for a three-hour forced blackout, they switched to backup generators, which were guaranteed fuel supply 24 hours a day, and were able to replenish fuel when needed. The data centers of Amazon and Equinix are likely to operate in a similar manner.
Disasters will continue to happen. Indeed, the San Francisco and Silicon Valley areas where I am located are also earthquake-prone areas. After three major earthquakes hit the Pacific coast, the situation in these areas is also worrying. The three major earthquakes included the Great Earthquake of Chile (8.8 magnitude) on February 27, 2010, the Christchurch Earthquake of New Zealand (magnitude 7.1) on February 22 and the Great Earthquake of Japan (9.0 magnitude) on March 11 ). The estimated magnitude of the San Francisco earthquake that occurred in 1906 reached 7.9. (This does not include the 7.0 earthquake of Haiti on January 12, 2010, which is not in the Pacific coast.)
Before the next disaster strikes, we have to think about it: if an unimaginable disaster occurs, your main system fails or is destroyed, how powerful a second data center that depends on the cloud environment can provide business operations and operations; also Think about reaching out to your neighbors if you do n’t fall after the disaster.
