  • ©Continuent 2013 5 With AWS, a complete, affordable LAMP stack, on demand, in minutes - but some assembly is required... apache/php haproxy MyApp Your mobile destination... MySQL AWS is a catalyst for Innovation What happens when your app becomes business critical for your customers?
  • ©Continuent 2013 Taking a Closer look at Amazon RDS, Amazon’s DBaaS Offering
  • ©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
  • ©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
  • ©Continuent 2013 9 apache/php haproxy MyApp Your mobile destination...Service encapsulation, RDS Style MySQL
  • ©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
  • ©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
  • ©Continuent 2013 How well does it work? RDS Multi-AZ failover
  • ©Continuent 2013 How well does it work? RDS Multi-AZ failover
  • ©Continuent 2013 App is able to connect at 22:11:45 - about 7 minutes later How well does it work? RDS Multi-AZ failover
  • ©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
  • ©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’
  • ©Continuent 2013 17 apache/php haproxy MyApp Your mobile destination... MySQL Service encapsulation, Tungsten Style
  • ©Continuent 2013 18 Tungsten Data Service apache/php haproxy MyApp Your mobile destination... Service encapsulation, Tungsten Style • Single endpoint for both writes and reads • Read-only resources visible and load balanced as they appear • Service-oriented connectivity can span sites

  • ©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?
  • ©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.
