License Mobility for Amazon Microsoft Deal

Friday, July 22nd, 2011

Amazon Web Services (AWS Reviews) announced last week that the Microsoft “license mobility with Software Assurance” (SA) program applies to AWS cloud server services.

That means that organizations with Microsoft volume licensing and SA agreements in place have a little more flexibility on how to use Microsoft application server products that were originally licensed for on-premises use. In many cases, organizations can transfer those licenses into a hosting company’s public cloud, including leveraging AWS’ infrastructure-as-a-service offerings to run applications as services, without incurring additional licensing costs.

Amazon claimed in its announcement that companies with volume licensing and SA agreements in place have been upgrading to the cloud using Microsoft’s mobility licensing option. For instance, they may move from using SharePoint 2007 on premises to using SharePoint 2010 on the AWS cloud.

What Really Happend with the Amazon Cloud Server

Thursday, April 28th, 2011

Around 1AM PST on Thursday April 21st 2011, one of the four availability  cloud hosting zones in the AWS US East region experienced a network fault that caused connectivity failures between EC2 instances and EBS.

This event triggered a failover sequence wherein EC2 automatically swapped out the EBS volumes that had lost connectivity with backup copies. At the same time, EC2 attempted to create new backup copies of all of the affected EBS volumes (they refer to this as “re-mirroring”).

While this procedure works fine for a few isolated EBS failures, this event was more widespread which created a very high load on the EBS infrastructure and the network that connects it to EC2. To make matters worse, some AWS users likely noticed problems and began attempting to restore their failed or poorly performing EBS volumes on their own.

All of this activity appears to have caused a meltdown of the network connecting EC2 to EBS and exhausted the available EBS physical storage in this availability zone. Because EBS performance is dependent on network latency and throughput to EC2, and because those networks were saturated with activity, EBS performance became severely degraded, or in many cases completely failed. These issues likely bled into other availability zones in the region as users attempted to recover their services by launching new EBS volumes and EC2 instances in those availability zones. Overall, a very bad day for AWS and EC2.

Amazon Cloud Hosting Now With Internet Access

Tuesday, March 15th, 2011

http://freehostingtips.info/wp-content/uploads/2011/02/Development-on-Cloud-hosting.pngAmazon Web Services is furthering their dominance in the cloud hosting by allowing users to make their cloud serverdirectly accessible to the internet (bypassing the need for a VPN).

Users can actually specify which of their Amazon VPC (virtual private cloud, also known as a cloud server to all the non-cloud techies) resources they wish to make directly accessible to the Internet and which they do not. Customers would have more control over the virtual networking environment, including selection of IP address range, creation of subnets, and configuration of route tables and network gateways.  This will allow them to overall have much more control and customization over their cloud server.

What does this mean?

When you break it all down is means that Enterprise users can create a public-facing subnet for web servers that have access to the Internet, and placing backend systems such as databases or application servers in a private-facing subnet with no Internet access (and a VPN connection).  They can now store large amounts of cloud data on the Amazon S3, with specific permissions being only allowed to VPC cloud server
