RDS today is used by thousands of customers from small startups to the world’s largest corporations.We have a predictable history of delivering reliable services and adding even greater functionality over time. (MAZ, RR, Caching)
RDS prestructure before adding new attributes, with NoSQL you do not have to do this it is a sparse schema. RDS creates DB on EC2 and EBS for you, gives you Host name and put and you take it from there with your fav SQL client. SimpleDB is in the DataPath, you dump the data and it creates the schema (Does Dynamo?)RDS Benefits – 1. Scale with modify API but there is an outage when you swap out instance types (e.g. from med to XL) but only takes a femins. Events are starting and done. IP address stays the same. Same for EBS add storage with no downtime or degradation in perf2. DB Backup and Restore – DB Snapshot or automated backup. 3. Monitor DB – recover from DB crash, EC2 crash, Gumi has been our number 1 customer for a few weeks over $250k in the last 4 weeksFunzio is in the top 5 and so is activisionEA, sony, bightgames also customers.We have been talking to playfish about DynamoDB but I don’t see them in the rds user base.Could not find zynga.
Standard N-Tier Layered Architecture : Logic Tier talks to Data TierData Tier: we have many different DB's depending on the problem space:SimpleDB : Operational Configuration and State goes hereNoSQL : Content Processing (e.g. article categorization), usage processing (e.g. what topics do most readers in England care about at 8am versus 10pm), etc...Memcached (a.k.a ElastiCache) : If you will query it twice based on simple key/value, it goes here.RDS: Reliable AND Complex queries needed? Go hereIn general, we found per user data needed by the presentation tier is best stored using RDS since most requests are user/session focused and requires complex logic based on new features or user interface designs. This includes stuff such as what social networks you belong to, your social interactions such as liking photos or reading articles, synchronization of state across multiple devices, etc.
So, who is using DynamoDB?Many companies within Amazon and outside Amazon.Amazon CloudDrive, Smugmug, Amazon retail are examples within Amazon.Smugmug is using us for storing their metadata on DynamoDB.Formpsring and Tapjoy are one of our early adopters.Finally, the shazam the popular voice recognition application for ads and music is using us to store its data for various applications.

Amazon RDS Tips For Success1. Leverage the Cloud for what it does best. Don’t bring old DC habits.2. Scale up for better performance.3. Use RDS for complex, real-time data.4. Use Read Replicas to augment write heavy databases. They are awesome.5. Leverage existing SQL knowledge and experience.6. Use copies of your database for testing new code. It’s trivial and saves time.7. Scale horizontally with sharding. Plan for it before you need it.
Relational Or Non-Relational?Factors Relational (RDS) NoSQL (DynamoDB) • Existing database apps • New Web scale applicationsApplication type • Business process-centric apps • Large # of small writes and readsApplication • Relational data models, transactions • Simple data models, transactionscharacteristics • Complex queries, joins and updates • Range queries, simple updatesScaling • Application or DBA architected • Seamless, on-demand scaling • Performance – developer architected • Performance – AutomaticQoS • Reliability and availability • Reliability and availabilitySkillset • SQL + Programming languages • Web style programming Possible to use both SQL and NoSQL models in one application
