Mysql – the best and most performant MySQL cloud solution

cloudMySQLperformance

I'm looking for a solid solution (~1GB of DB space). Speed is crucial and I'm happy to spend up to $100 a month on a decent solution. The database will be used by a series of desktop applications developed on .Net.

I've already tested both Xeround and Amazon EC2 solutions, but the results were similar and pretty disappointing.

I would highly appreciate any suggestion based on your experience.

Update:

I've recently tested an EC2 m1.xlarge and a RDS db.m1.large. Similar results as with micro instances. Tests were done from Europe and America. Results:

  • Europe to EC2/RDS – 22 min.

  • America to EC2/RDS – 8 min.

  • local to local – 10 sec.

I'd like to chime in on what has been said in the question and in the comments.

XEROUND

Exactly one year ago today, I wrote an answer about the Xeround DB Service : Database as a service (DbaaS) over dimensions--performance, scalability, & reliability?

Granted, you have the following:

I just instantiated a Xeround Free Version Sevice and ran SHOW ENGINES; and got this

No InnoDB ??? Not much has changed.

How about variables for the Storage Engine?

Looking at the API, I do not believe you can tune anything. You are basically at the mercy of the Storage Engine.

I have also tried loading data into it and using the INFORMATION_SCHEMA database to report back to me space usage. For the XEROUND Storage Engine, I get back nothing. MyISAM is OK.

There are still other limitations with Xeround (Oct 12, 2012) you have to read and consider.

Amazon RDS

While the service bears the hallmarks of a well-trusted brand name, the service must still be evaluated in terms of two things:

  1. Cost
  2. Configuration
  3. Performance

While cost is at one's discretion, I will discuss the other aspects

CONFIGURATION

  • You have no access to a my.cnf
  • Any variables to be configured beyond default requires an API call to the DB Parameters Group followed by a restart of the RDS Instance.
  • There are two things you cannot change no matter what Memory Class you choose
  • See my post from Aug 02, 2012 : Local database vs Amazon RDS

PERFORMANCE

This goes hand-in-hand with CONFIGURATION. Any tuning aspects you wish to make are subject to the limitations and functionality of the RDS API. Not all Performance enhancements for InnoDB are possible because of Amazon's policies meant to provide a share-everything environment for normal RDS users (unless you can come up with more $$$ for more IOPs and things of this nature).

EPILOGUE

Amazon EC2 may be your best option if your want more flexibility/autonomy for

  • configuring MySQL
  • voluntarily paying
    • RAM
    • Disk
    • IOPs
  • tuning InnoDB

Given the times you just reported in the question, nothing short of due diligence is required for tuning (possibly rearchitecting) your app for Cloud Usage.
