10gen and Microsoft Partner to Deliver NoSQL in the Cloud
We at 10gen are excited about our ongoing collaboration with Microsoft. We are actively leveraging new features in Windows Azure to ensure our common customers using MongoDB on Windows Azure have access to the latest features and the best possible experience.
In early June, Microsoft announced the preview version of Windows Azure VM, which enables customers to deploy and run Windows and Linux instances on Windows Azure. This provides more control over actual instances as opposed to using Worker Roles. Additionally, this is the paradigm that is most familiar to users who run instances in their own private clouds or on other public clouds. In conjunction with Azure's release, 10gen and Microsoft are now delivering the MongoDB Installer for Windows Azure.
The MongoDB Installer for Windows Azure automates the process of creating instances on Azure, deploying MongoDB, opening up relevant ports, and configuring a replica set. The installer currently works when used on a Windows machine, and can be used to deploy MongoDB replica sets to Windows VMs on Azure. Additionally, the installer uses the instance OS drive to store MongoDB data, which limits storage and performance. As such, we recommend that customers only use the installer for experimental purposes at this stage.
In both cases, by using Azure data disks, this implementation provides data safety given the persistent nature of disks, which allows the data to survive instance crashes or reboots.
Furthermore, Azure's triple-replication of the data guards against storage corruption. Neither of these solutions, however, takes advantage of MongoDB's high-availability features. To deploy MongoDB to be highly available, one can leverage MongoDB replica sets; more information on this high-availability feature can be found here.
Finally, customers who would like to deploy MongoDB replica sets to CentOS VMs can follow these basic steps:
Sign up for the Windows Azure VM preview feature
Create the required number of VM instances
Attach disks and format
Configure the ports to allow remote shell and mongodb access
Install mongodb and launch
Configure the replica set
Detailed steps for this procedure are outlined in the tutorial, ...Deploying MongoDB Replica Sets to Linux on Azure.â€œ
