3. About Us About Xeround, the company: Founded in 2005 and backed by solid VC investors Initial premise: Telco-Grade, Real-Time DBMS Already deployed in live Telco production – T-Mobile US, Pelephone ISR About Xeround, the technology and service: Designed from day one for a Cloud ecosystem Patented native Virtualized Cloud DB, balancing Innovation with Traditional SQL Simple to use, seriously powerful About myself: 17+ years around database-based applications and DBMSs in various capacities Last 4.5 years with Xeround doing product, project and operations management There is a crack in everything – thats how the light gets in (Leonard Cohen)

4. (Some) Common Pains with the Database Tier Database server installation Operating system installation Configuration: storage, networking… Database server maintenance Patches and upgrades Backup (and restore) policies Database operation Monitoring High Availability: fail over (& failback) Scaling

5. Xeround SQL Cloud Database-as-a-Service Elastic, Available & Simple! Worry Free philosophy – operational aspects all handled by the service Robust functionality, full compatibility with MySQL Self-service management portal

8. The virtualized Database is built from three separate elements: Load Balancer SQL Engine Data Store Each element is scalable Physical resources for each element are managed individually Load Balancer Load Balancer Load Balancer SQL Engine SQL Engine SQL Engine SQL Engine SQL Engine Data Store Data Store Data Store Data Store Virtualized Database Layers

9. Load Balancer – The gateway to a database instance Maintains transaction stickiness and balances the load between the SQL engine instances Handles failover of SQL engines SQL Engine - MySQL Façade implementation Processes SQL statements into distributed parallel plan of execution Gathers the results from the different processes and assembles the final result for the application Data Store - Distributed data stores, which maintain the data in its different representations DHT, Distributed B-Tree and Object Store, which are the basic data services required by the database Pluggable persistency layer Virtualized Database Layers, cont.

10. DBaaS Resource Manager uses the Cloud API to acquire resources for the database service and to provision the service elements on those resources Cloud Resources Load Balancer Load Balancer Load Balancer SQL Engine SQL Engine SQL Engine SQL Engine SQL Engine Data Store Data Store Data Store Data Store DBaaS Resource Manager DBaaS Resource Manager Cloud API DBaaS Resource Management

11. Demonstration: Connect to Your DB Instance

12. Connecting to Your Cloud Database 100% compatible with MySQL No code changes required to port an existing application Built-in advanced features (e.g., replication, load balancing…) are transparent to the user

13. The DB Instance Manager is responsible for creating databases, by allocating slices from the Load Balancer, the SQL Engine and the Data Store physical resources.

14. Demonstration: Scale Your Database, Automatically!

15. 3 Ways to Scale Your Database Instance 1. Manual Scaling - via the self-service portal GUI 2. Auto-Scaling Currently: thresholds-based rules Near-future: advanced rule- and policy-based scaling 3. API - enables programmatic access to the services capabilities

17. Demonstration: Server Crashes, Your Database Survives

18. P1 P2 P3 P4 P1 P2 P4 P2 P3 P4 P1 P3 A database With 4 virtual partitions Each Virtual partition is replicated across multiple servers. If any one of the servers fails, all data is still available and the DB is still operational This enables a recovery process to occur, by acquiring a replacement server, and re-sync the server from existing partitions Host Data Distribution

19. P1 P2 P3 P4 P1 P2 P4 P2 P3 P4 Host Fault Tolerance & Automatic Healing 1) When a server fails, surviving replicas maintain the service P1 P3 2) The system heals itself by automatically re-growing the missing replicas 3) A pool of failover servers is kept online to expedite process P1 P3

20. Summary Xeround offers a SQL Cloud DBaaS that is: Simple to use Elastic so it always fits your requirements Highly available Fully-compatible with MySQL Xerounds DBaaS frees you from worrying about: Patching and upgrading your database server Operating a backup policy Planned and unplanned downtime
