Even though Microsoft is promoting the cloud service as its new growth engine and emphasizing "Cloud First", service disruptions are fueling doubts about its technology and stability in Korea.
According to Microsoft and industry sources on July, it has been found that Korean users of the Azure Cloud Service were not able to access the service due to one hour’s network failure each in the morning and afternoon in the Seoul Legion of Microsoft Korea (multiple data centers) of Seoul on June 25. Microsoft Headquarters analyzed that a flaw in the router (network relay device) software of the Microsoft Busan Legion in Korea affected the Seoul Legion. Microsoft found related problems with 18 other routers and patched them, but customers suffered from severe access failures for a long time.
"Microsoft apologizes to customers affected by this failure," Microsoft Global Headquarters said on its homepage. "We will take steps to improve the Azure platform process to prevent this problem from reoccurring in the future." However, Korean customers are becoming increasingly dissatisfied with Microsoft Cloud Azure.
"I went through an unstable service as the service platform (PaaS) went down and came back. I had no choice but to wait helplessly," said a Korean customer using Azure. "Failures of the Microsoft Cloud Service have taken place multiple times. No one can recommend the use of the Azure Service in Korea,” another customer said. "Fortunately, the failure occurred to a server under development. If it had taken place and affected a server providing service for one hour, it would have been a huge horrible disaster," said a chief technology officer (CTO) at a start-up in Korea.
Like this, Microsoft’s cloud disruption has occurred not only in Korea but also in the US, Germany, Australia, and Japan among others all over the world, the point is Microsoft Korea’s poor response to the problem. “When customers call Microsoft Korea to report failures, they often hear Microsoft employees say, ‘Does such a problem really happen?’ and do not know situations,” a customer said. “Not the global headquarters of Microsoft but Microsoft Korea becomes aware of a failure several hours after the failure breaks out.”
Therefore, some industry experts have expressed concerns over Microsoft’s tapping into the public cloud market which requires high reliability. "If Microsoft, which represents cloud services together with Amazon and IBM, provides unstable services at a time when the Korean government promotes public organizations’ introduction of private cloud services, the public organizations will become loather to introduce private cloud services due to stability and security concerns," an industry source said,
