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 – that’s how the light gets in (Leonard Cohen)

(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

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

• 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

Virtualized Database Layers

• 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.

DBaaS Resource Manager uses the Cloud API to acquire resources for the database service and to provision the service elements on those resources

Connect to Your DB Instance

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

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.

Scale Your Database, Automatically!

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 service’s capabilities

Database Instance Scaling

Each element may be scaled separately:

Load Balancer = More connections

SQL Engine = More queries/ complexity

Data Store =More data

A database With 4 virtualpartitions

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

Fault Tolerance & Automatic Healing

1) When a server fails, surviving replicas maintain the service

2) The system heals itself by automatically “re-growing” the missing replicas

3) A pool of failover servers is kept online to expedite process
