The main failures of cloud services in 2012, and what conclusions you can take from this
Based on the recent report IWGCR (International Working Group on Cloud Computing Resiliency) every year on the cloud-computing is unavailable, in average, within 7.5 hours. Companies that fully or partially use the cloud for their applications and services, this year, suffered a few times. Let's look at the biggest failures in the use of cloud services in 2012.
Microsoft Azure
The largest and most extensive crashing Microsoft Windows Azure was in February, he touched upon all the geographic locations, a full recovery of the service lasted more than 24 hours. Microsoft stated that the failure was caused by a bug in the software related to the wrong calculation of time and date for a leap year. The problem has caused angry reaction from users of the service, who had expected greater coverage of issues and greater communication on the part of Microsoft.
In July, the service of cloud computing Microsoft Azure was again inaccessible, this time in Western Europe, the duration of failure was 2.5 hours. The reason was a misconfigured network device that led to a problem with connection of users.
Later in the autumn had another failure associated with the work Office365, during which were unavailable to millions of users ' mailboxes.
Amazon Web Services
A power outage of Amazon Web Services in June cut off users from the services for 6 hours. Affected services: Amazon Elastic Compute Cloud, Amazon Relational Database Service and AWS Elastic Beanstalk in the region U.S. East datacenter in Virginia. In addition, affected companies provide services for the management of clouds and PaaS providers such as: Stratalux, Digitaria, Heroku and PaaS service provided Salesforce.com. Popular websites: Netflix, Pinterest, Reddit, Forsquare and Instagram also suffered because of this failure.
Less than a month suffered a second failure in the AWS, and then one of major clients has publicly stated that he ceases to use the services of Amazon and are forced to look for alternatives.
Apple
In September, a large number of users that the cloud service could not access their mailboxes. But there was a problem with the Central iCloud service, so it was common for users of computers running Mac OS, iOS users and for users using Web interface iCloud.com.
Google Gmail
This year Google's Gmail service suffered more setbacks than in the past. The first failure occurred in April and lasted one hour. The problem is grazed less than 10 percent of users, the main reason was in the wrong configuration when you perform a routine system update. The second crash occurred in June and touched less than 1.5 percent of users.
Opinion
Despite all the precautions taken by cloud service providers, outages occur regularly for different reasons such as human errors, technical failures or natural disasters. But that is no reason to abandon the cloud. All these factors can be controlled with the use of a comprehensive plan for disaster recovery and failover plan. Over time, the reliability of cloud platforms will continue to grow, and resiliency will tend to 100% (real, not declared by the marketing Department). Sooner or later the iron will be supplanted by cloud-based hosting.
