Chaordic Systems is a Brazilian company that specializes in personalization. The company focuses on e-commerce, helping users find products that are most valuable to them, and helping retailers increase profits. Chaordic Systems collects data about users’ behavior, processes that data using advanced machine learning algorithms, and then personalizes the user experience through targeted service recommendations. Some of the biggest retailers in Brazil are Chaordic customers such Livraria Saraiva and Nova.com group (including Casas Bahia, Extra, and Ponto Frio e-commerce sites).
João Bosco, co-founder and CTO of Chaordic Systems, explains the challenges the company faced prior to signing on with Amazon Web Services (AWS): “We decided to work mainly with big retailers, with a lot of user traffic and many products. To truly scale the solution, we needed a system to be very fast, so users wouldn’t notice the difference between retailers’ content and ours. We needed a very robust solution that could handle a high workload and respond quickly, especially during peak times like Black Friday.”
“The costs involved in building a data center to solve this problem were prohibitive, especially for a startup business with no income at the time”, continues Bosco, “Going to the cloud was the obvious decision to make.”
Chaordic Systems started looking for services that offer cloud solutions. Bosco states, “We were already fans of AWS for its innovative spirit, high quality products, and providing the infrastructure behind Amazon.com. AWS had the most stable and advanced cloud solution, so we decided to give it a try.”
Chaordic Systems currently uses AWS for almost everything including development. There is one server running within the company and everything else is on the AWS cloud. The following diagram illustrates the company’s main platform architecture:

Bosco outlines some of the ways in which Chaordic Systems uses AWS:
The company’s main platform is written in Java and runs on Jetty, nginx, and HAProxy. It uses a local cache (Ehcache), a Cassandra cluster, some MySQL servers, and a cluster of Memcache.
The team also uses Python for scripting. Their tools for interfacing with AWS are written in Python and use primarily Amazon EC2 API tools. For monitoring, they use New Relic, Nagios, Ganglia, and Pingdom. They use Puppet and Amazon S3 to help launch instances.
Chaordic Systems has seen the following benefits from using AWS:
Chaordic Systems appreciates the frequency with which AWS launches new products. Bosco says, “We always look forward to the next product release. I don’t think we would even have a business without AWS.”
