MongoNYC 2012: MongoDB on Windows Azure

MongoNYC 2012: MongoDB on Windows Azure, Sridhar, 10gen. A brief overview of building and deploying applications using MongoDB Replica Sets on Windows Azure followed by an interactive session to discuss recommended configurations and tips (and tricks).

Transcript

2. Deploying MongoDB on Azure Sridhar Nanjundeswaran, Software Engineer, 10gen @snanjund sridhar@10gen.com
3. Agenda • Why? • Implementation details • Usage walkthrough
4. Windows Azure Platform • Microsoft’s cloud platform to build, host and scale applications • Hosted in Microsoft data centers Compute Storage Management Relational data Marketplace Middleware CDN Management
5. MongoDB on Windows Azure
6. Details of the MongoDB worker role Implementation Details
7. Highlights • Uses standard MongoDB binaries • Code is open sourced • Works with VS Express • Data persisted on blob storage
8. Details • OnStart • Register change notifiers • Mount Blob • Start mongod • ReplSet Initialize • Run • Run cloud command
9. Details - contd • OnStop • Stepdown • Stop mongod • Unmount blobs
10. Challenges • Debugging • IP potentially changes on reboot • DNS within mongodb. New cloud command • Testing IP change • Reduce instance count and increase • Keeping both sets of configurations in sync
11. Download->Setup->Develop->Debug->Deploy Now let’s use it
12. Setup: Setup Develo p Debug Deploy Monitor
13. Develop • Use solution without sample • Add your worker/web role code to it Setup Develo p Debug Deploy Monitor
14. Debugging - Locally • Debugging on emulator works great. • Cloud storage is emulated as local mounted drives • Cannot use to test config changes • csrun /run:<dir>;<config> • csrun /update:<depl id>;<new config> • csrun /remove:<depl id> Setup Develo p Debug Deploy Monitor
15. Deploy • Create storage account • Get key • Create service • Specify storage account/key in solution • Enable RDP when packaging Setup Develo p Debug Deploy Monitor
16. Debugging - deployed • Change runtime config and use RDP • MongoDBLogVerbosity - increase • RecycleOnExit – set to false • Tools • AzureDiagnosticsManager – get diagnostics logs, perf counters from deployed instance • AzureHostedServicesManagerBinary – edit config of running instance • CloudXplorer – download blobs Setup Develo p Debug Deploy Monitor
17. Monitor Setup Develo p Debug Deploy Monito r
18. Pitfalls • Bandwidth • Requires at least medium instance • Debugging locally • Config change cause restarts • Deployment • Storage and compute in same region, use affinity group • Check http vs https • Continuous restarts
19. The Future • Scale out using replica sets • MongoDB Monitoring • Backup and Recovery • Sharding • Publish logs to external storage?
