Airbnb has grown significantly over the last 3 years. To support demand, the company uses 200 Amazon Elastic Compute Cloud (Amazon EC2) instances for its application, memcache, and search servers. Within Amazon EC2, Airbnb is using Elastic Load Balancing, which automatically distributes incoming traffic between multiple Amazon EC2 instances. To easily process and analyze 50 Gigabytes of data daily, Airbnb uses Amazon Elastic MapReduce (Amazon EMR). Airbnb is also using Amazon Simple Storage Service (Amazon S3) to house backups and static files, including 10 terabytes of user pictures. To monitor all of its server resources, Airbnb uses Amazon CloudWatch, which allows the company to easily supervise all of its Amazon EC2 assets through the AWS Management Console, Command Line Tools, or a Web services API.
In addition, Airbnb moved its main MySQL database to Amazon Relational Database Service (Amazon RDS). Airbnb chose Amazon RDS because it simplifies much of the time-consuming administrative tasks typically associated with databases. Amazon RDS allows difficult procedures, such as replication and scaling, to be completed with a basic API call or through the AWS Management Console. Airbnb currently uses Multi-Availability Zone (Multi-AZ) deployment to further automate its database replication and augment data durability.
