  6. 6. ©Continuent 2013 Taking a Closer look at Amazon RDS, Amazon’s DBaaS Offering
  7. 7. ©Continuent 2013 What does ‘managed’ mean? • DBMS instance is up and running in minutes, fully integrated with service policies, and bound to a public IP address • Automated backups plus point-in-time recovery • Provision read slaves with a few clicks of a mouse • High-availability options are available • Instances can be easily resized • Software updates can be automated
  8. 8. ©Continuent 2013 How do I use it? • Add hosts to security group • Configure your application to use the ‘endpoint’ provided • Applications that already make a distinction between database connections used for writes versus those used for reads can make easy use of read slaves • Automation of backups, failover, slave provisioning etc. happen behind the scenes

  10. 10. ©Continuent 2013 10 apache/php haproxy MyApp Your mobile destination... Multi-AZ Instance Active Multi-AZ Instance Standby Synchronous Block-level Replication Read Slave Service encapsulation RDS Style • Applications reference ‘service’ via ‘endpoint’ • Single endpoint for writes • Zero or more endpoints for reads
  11. 11. ©Continuent 2013 How well does it work? RDS Multi-AZ failover • Failure is detected - can test via reboot • Actual failover appears to be completed within about 20 seconds - depends on size of databases etc. • Some applications may not ‘see’DNS interruption and may not re-connect • DNS Changes need to propagate - can take minutes. In my example, it took about 7 minutes and I needed to restart the app for it to ‘see’ the DNS change

  15. 15. ©Continuent 2013 Other RDS Limitations • No cross-region replication • Only runs in AWS • No cross-cloud/multi-data-center operation • Black-box - difficult or impossible to diagnose and correct problems with replication
  16. 16. ©Continuent 2013 Introducing Continuent Tungsten Cloud-scale DBaaS • Runs wherever you need your data to be • Fast failover - typically 5-15 seconds - does not rely on DNS • Built-in load balancing - applications connect to a single IP address to access all data resources • Compute/DB resources are ‘open’ - no black boxes here • Full resource utilization - no ‘standby’

  23. 23. ©Continuent 2013 Modernizing Medicine Mission Modernizing Medicine® is transforming how healthcare information is created, consumed and utilized in order to increase efficiency and improve outcomes. Its product, Electronic Medical Assistant® (EMA™),  is  a  cloud-based, specialty-specific electronic medical record (EMR) system with a massive library of built-in medical content, designed to save physicians time. Available as a native iPad application or from any web-enabled Mac or PC, EMA adapts to each provider’s unique style of practice and is designed to interface with hundreds of different practice management systems. Today, Modernizing Medicine provides specialty-specific offerings for the dermatology, ophthalmology, optometry, orthopedics and plastic and cosmetic surgery markets, and to more than 1,100 physician practices across the country.

  24. 24. ©Continuent 2013 Electronic  Medical  Assistant  (EMA™) • Saves doctors' time by eliminating the need to transcribe notes, allowing the Doctor to focus on the patient. • EMA learns preferences and adapts to the doctor which reduces time spent on coding, all with a touchscreen interface on the iPad • EMA grand rounds provides statistical results of treatments across millions of patient encounters
  25. 25. ©Continuent 2013 Database technology pain points • setting up/maintaining replication • need for high-availability • protecting patient data (encryption, data at rest, data in transit) • massive and unpredictable growth • Big data -- we have the data to revolutionize medicine, but how do we do it?
  26. 26. ©Continuent 2013 How we are addressing the issues • Tungsten takes care of replication and high- availability • leveraging AWS, pod design, automatons to deploy new pods • file system encryption, S3 encryption, SSL, Continuent Tungsten for all db traffic • taking small steps. maybe we will replicate data from all pods into central DB, using Tungsten. Then transform data, create datamarts.

  33. 33. ©Continuent 2013 What else can Tungsten do? • Cross-region fail over with a single command • Multi-site, multi-master architectures supported • Run services cross-cloud i.e. AWS to Rackspace Cloud etc. • Applications can specify ‘read affinity’ in order to read from local resources
