Running Databases on AWS. Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while managing time-consuming database administration tasks, freeing you up to focus on your applications and business. Amazon RDS gives you access to the capabilities of a familiar MySQL, Oracle, SQL Server, or PostgreSQL database engine. This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS.
Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period and enabling point-in-time recovery. We recommend Amazon RDS for customers who have a combination of needs such as: Multi-AZ deployments are presently supported for Amazon RDS for MySQL, Oracle, and PostgreSQL.

August 4, 2011 by Baron Schwartz14 Comments A while ago I started a series of posts showing benchmark results on Amazon EC2 servers with RAID’ed EBS volumes and MySQL, versus RDS machines. For reasons that won’t add anything to this discussion, I got sidetracked, and then time passed, and I no longer think it’s a good idea to publish those blog posts in the format I was planning.
Instead, I want to write an overview of these two approaches to hosting MySQL in the Amazon cloud. In general, MySQL performance overall on EC2 and EBS isn’t always great in comparison to what you can get on physical hardware, even low-to-medium sized servers. It’s not that it’s terrible (in most cases), but it’s not always great. Here’s why: you’re limited in the number and speed of CPU cores you can get, and I/O performance can be highly variable. None of these characteristics is a bad thing in itself. Here are some observations you can consider. These observations lead to the following guidelines. RDS FAQs. Q: What is Amazon RDS? Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud.
It provides cost-efficient and resizable capacity, while managing time-consuming database administration tasks, freeing you up to focus on your applications and business. Amazon RDS gives you access to the capabilities of a familiar MySQL, Oracle, SQL Server, or PostgreSQL database. This means that the code, applications, and tools you already use today with your existing databases should work seamlessly with Amazon RDS. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period. Q: What is a database instance (DB Instance)? You can think of a DB Instance as a database environment in the cloud with the compute and storage resources you specify.
Q: What does Amazon RDS manage on my behalf? Q: When would I use Amazon RDS vs. RDS is based on EBS. Q: What is Amazon RDS?

Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period. You benefit from the flexibility of being able to scale the compute resources or storage capacity associated with your relational database instance via a single API call or few clicks of the AWS Management Console . Q: What is a database instance (DB Instance)? RDS vs DIY MySQL. As I was researching online whether Amazon RDS was a viable option, I had a hard time finding reliable benchmarks.
The authors of this good book on EC2 mention it to be a bit faster, but without further clarification. The best benchmark I could find was this one. It uses the sysbench tool to test an EC2 instance vs RDS, exactly what I need. It provides the tools for benchmarking and pointed to the difference between running 1 and 10 threads. However, for me this benchmark was missing some vital information, therefore I decided to run my own benchmark using sysbench in a very similar way, with the following adjustments: I’ve used a much bigger dataset: I’ve set it to use 50 million objects, in order to create a 12GB database that will surely not fit the 1.7GB memory.Some parameters like: instance disk vs EBS and MySQL configuration were unspecified I’ve used the following setups: A small EC2 instance in the USeast region, with Debian squeeze and a standard MySQL install. 50 Threads.
