Amazon to Launch Cloud Data Center in Korea

Amazon’s announcement, which the company’s chief cloud evangelist Jeff Barr made in a blog post Wednesday, is yet another example of US-based cloud giants going aggressively after Asia’s rapidly growing cloud services market.
Other recent examples are IBM’s deal with Chinese data center provider 21Vianet to provide its Bluemix Platform-as-a-Service to customers in China and the launch of IBM’s first SoftLayer data center in India. Microsoft launched three cloud data centers in India earlier this year.
Asian cloud service providers are expanding data center capacity in the region too. Chinese e-commerce and cloud giant Alibaba recently brought online a new data center in the Zhejiang Province.
Barr listed existing Korean customers that will be able to take advantage of Amazon’s new cloud data center capacity when it comes online. They include startups, gaming companies, and enterprises, the latter category including the electronics giant Samsung.
“These customers (and many others) have asked us for a local region,” Barr wrote. “We are looking forward to making it available to them and to many other enterprises, startups, partners, government agencies, and educators in Korea.”

Amazon brings Microsoft users into AWS with Active Directory service

Amazon has launched an AWS Directory Service for Active Directory, a fully managed implementation of Microsoft's authentication and user management service.

Using Active Directory in Amazon's cloud will enable companies to bring applications including SQL Server, SharePoint and custom applications built with .NET onto AWS. That's useful for businesses trying to move into the cloud from an on-premises deployment of Microsoft's software. 

When companies start using the service, it creates a pair of domain controllers connected to a user's virtual private cloud running Windows Server 2012 R2. Each domain controller runs in a different availability zone of a user's choosing inside a single region, and Amazon will handle the nuts-and-bolts of managing things like host monitoring, data replication and snapshots.

Administrators will be able to configure a trust relationship between their on-premises Active Directory and the AD in Amazon's cloud, so that users can sign in to both systems using one login. 

Companies can try the service for free for one month or 750 hours, whichever comes first. After that, the service costs US$0.40 per hour. 

It's an interesting move for Amazon, since one of the key products Microsoft uses to push its cloud services into large enterprises is Azure Active Directory -- a fully managed, cloud-based implementation of Microsoft's authentication and user management service with a whole bunch of other services and integrations baked in. It's an easy way to get one part of a business into Azure, which Microsoft can then use to try and upsell companies on other cloud services. 

How Amazon plans to expand this service to better compete against Azure AD remains to be seen, especially as it continues to fight with Microsoft to pursue dominance in the public cloud market.
