This deck showcases how WSO2 Storage Server can be used for data source provisioning in your environment, which will contain functionalities to create and manage relational databases and NoSQL data stores as well. He will also look at how WSO2 Data Services Server can be used to access that data, where it has more mobile friendly, native support for data formats such as JSON and RESTful data access.

1. Store and Deliver Data to the
Mobile App Edge:
WSO2 Storage-as-a-Service and
Data-as-a-Service

2. The Requirement
● Mobile application friendly data store management and data
access
– Data source provisioning
– Data services
– Mobile friendly protocols / data formats

3. Storage as a Service
● Data Storage Provisioning
● Ideal for SMEs
– No need to maintain your own hardware
– No need to have specialized expertise to setup / maintain
– Pay as you go
● Rapid Application Development

4. Storage as a Service...
● WSO2's offering: WSO2 Storage Server
● Multiple Data Store Types
– RDBMS
– Cassandra
● Databases / Users / Permission Management
● Multi-tenant data source provisioning
● Used internally in WSO2 App Factory

5. Data as a Service
● Data operations on a data store exposed as standard services
● No duplication, encourages re-usability
● Creates a data access layer by abstracting out data repositories
● Service governance
– Service design / development is managed properly according to
the requirements
– Runtime governance aspects also to enforce SLAs such as
performance of the services

6. Data as a Service...
● WSO2's offering: WSO2 Data Services Server
● XML based declarative language for defining data services
● Service data input mapped to a target data source query and the
output from a data source mapped to the service result

7. Data as a Service...
● WSO2 Data Services Server Features :-
– Multiple data source types, and custom data sources for
extensibility
– Data federation
– Data batch support
– Transactional data access
– Secured data access
– Multiple protocol and data type support, e.g. HTTP, JMS, XML,
JSON
– RESTful data access

8. Mobile Application Data Access
Challenges
● Limited access to data store clients
● Lightweight client-side processing
● Mobile friendly transports and data types
● Rapid development
● Security and performance
● Native vs HTML5

9. Mobile Data Services
● Creating a data access layer
● Access control, security aspects defined by data services
● Clear service interface accessed using well known transports, all
data related actions offloaded to data services layer
● RESTful services with JSON data payloads

10. Integrated Solution
● WSO2 Storage Server for data source provisioning
● WSO2 Data Services Server for exposing created data source as
data services
● Mobile application, either HTML5 or native applications access
data services using HTTP/HTTPS with JSON/XML data payloads

12. Upcoming enhancements
● WSO2 Storage Server
– Additional data store support: MSSQL, Oracle databases
– Policy driven provisioning
● Based on QoS / SLA params
– Storage and bandwidth monitoring
– Usage policies for billing
● WSO2 Data Services Server
– Data quality / data filtering capabilities
– Complex input data support
– Advanced query composition inside data services
– Improved transaction support
– Finer extension support, data source, queries, interceptors etc..
