Comparing Cloud Databases: SimpleDB, RDS and ScaleDB
+0 Vote Up -1Vote Down

Amazon’s SimpleDB isn’t a relational database, but it does provide elastic scalability and high-availability. Amazon’s recently announced Relational Database Services (RDS) is a relational database, but it doesn’t provide elastic scalability or high-availability. If you are deploying enterprise applications on the cloud (including Amazon Web Services), you might want to look at ScaleDB because it is a relational database and it does provide elastic scalability and high-availability.

Amazon describes SimpleDB by comparing it to a clustered database:

"A traditional, clustered relational database requires a sizable upfront capital outlay, is complex to design, and often requires …

Three key things to know about moving MySQL into the cloud.
+4 Vote Up -0Vote Down

The question "what problems will I have when migrating to the cloud" gets asked often enough. If by cloud you mean Amazon EC2, then from a technical perspective there isn't much that changes. The biggest thing that changes is just how you pay your bill.

Having said that, there's still a few potential gotchas:

  1. There are no Virtual IP addresses. Most High Availability tools (like MMM or DRBD+Heartbeat)
    work on the principal of having a floating IP address which is used for the application to connect to the current master. With EC2, you can't do this.

Your opinion on EC2 and other cloud/hosting options
+0 Vote Up -0Vote Down

EC2 is nifty, but it doesn’t appear suitable for all needs, and that’s what this post is about.

For instance, a machine can just “disappear”. You can set things up to automatically start a new instance to replace it, but if you just committed a transaction it’s likely to be lost: MySQL replication is asynchronous, EBS which is slower if you commit your transactions on it, or EBS snapshots which are only periodic (you’d have to add foo on the application end). This adds complexity, and thus the question arises whether EC2 is the best solution for systems where this is a concern.

When pondering this, there are two important factors to …
