Is it possible to migrate from SQL DB small plan to premium plan? Assume we have started with the small plan and data exceeds 10GB. Can the plan be migrated to premium? If yes, does this include data movement?
No, currently there's no way to automatically migrate your data. You have to manually migrate from the small to the premium plan. You should be able to use the SQL Database console to manually export your data, then once you've subscribed to the premium plan, you should be able to load the data via the SQL DB Console as well.
The SQL Database console does not have ability to import/export data. To move data from one SQLDB instance to another, consider to use the Bluemix DataWorks Data Load REST API.

Alternatively, you may also create a Bluemix app so you may import and export data from/to SQL Database service:

I am building an app that allows people to share items with other people in the community. I wanted to use AWS as my platform.
My idea was to use react Native for the app. AWS Cognito for the authentication. AWS lambda for the server calls. Relational database for storing data about the items and user data such as geolocation. Dynamodb for real-time chat, requests for borrowing and transaction data between users. My primary focus is low cost and I was thinking of using PostgresSQL for relational database.
What do you guys think of my database choices. Of course the PostgresSQL database on rds. Is there a flaw in database plan so far? Any help would be greatly appreciated.
I would probably just use DynamoDB for everything in your application. I don't see a real need to storing some of your data in an RDS database here. However if you definitely need a relational database, I would suggest AWS Aurora Serverless so that your entire application would be using serverless AWS services. Also, normal relational database connection pools don't work that well in AWS Lambda, so I would suggest using the new Data API.
I'm wondering whether it's possible to make GAE create more than 7 sql database backups and how much that will cost. They don't seem to mention this possibility in their document.
I'm afraid it's not possible to have more than 7 backups at a time for Cloud SQL. The goal is to use the backups as a last line of defense for restoring a broken database. If you need snapshots over time, you can use the Export functionality to save dumps to a Cloud Storage bucket.
I have an on-premise database. At the same time I have the database on cloud. When the on-premise database gets updated the SQL Azure database should also get updated. Only the changed fields should be updated. The rest should remain the same. How can this be achieved in minimal time?
There is a No code solution called Data SYNC CTP2 but you need to request access which unfortunately stopped for now. (http://connect.microsoft.com/sqlazurectps)
You could try using SYNC framework. Have a look at this article: http://blogs.msdn.com/b/sync/archive/2010/08/31/sql-server-to-sql-azure-synchronization-using-sync-framework-2-1.aspx
just a note. Neither Sync Framework or Sql Azure Data Sync does column level change tracking or synchronization. When a column in a row is changed, the entire row is sent during synchronization.
As Paras mentioned, Sql Azure Data Sync is in CTP stage (CTP2 now, with CTP3 supposed to come out this summer).
Sync Framework 2.1 however already supports synching with Azure.
check out Synchronizing with SQL Azure using Sync Framework
for links to various walkthroughs/samples
Is there any way to migrate and synchronize data between an on-premise SQL database and SQL Azure database apart from sync framework?
The sync framework works fine for small databases, but when it comes to large databases its not working. Is there any possible way to migrate and synchronize using change datacapture and SSIS?
you might want to clarify what you mean by "its not working". Are you having issues during the initial sync or incremental sync? what's the sync direction required for your sync? upload/download/bidirectional? do you get an error?
there are many ways to do the migration,
for synchronization, apart from Sync Framework, you may also look at Sql Azure Data Sync (largely based on Sync Framework too).
and yes, you can use Change Data Capture and SSIS if you want but note that Sql Azure doesnt have the same Change Data Capture feature as Sql Server so you'll be fine using CDC and SSIS for on-premise to Sql Azure sync only. You have to figure out another way to do change tracking on the Sql Azure side.
I am creating a simple application and getting stuck with data storage option. To begin with I would like to use SQL Server as my data storage. I will not be using any special features of SQL Server, its pure tables with CRUD operations.
Now I should be able to switch the underlying data store to either SQL Data Services or Amazon S3 by changing few configuration parameters.
Is this possible??? If yes, can anyone provide high level guidance on how to go about it? Do I need to use Entity Framework to begin with SQL Server? Does Entity Framework supports SQL Data Services? Any common component which supports both SQL Data Services and Amazon S3?
Too many questions!!!
Thanks for the help in advance.
The closest ORM I know of is LightSpeed. I've never used it though. Personally, if the end goal is to use cloud storage, I'd probably just use cloud storage from the get go...
If you are going to use Amazon's SimpleDB, M/Gateway has a open source db that mimics their API.
