Overview

● Multitenancy● Autoscaling● Cloud middleware platform

Mission

● WSO2 aims to provide the best complete Enterprise Software Platform:

– for Cloud – to be used in EC2, Azure, VMware, Private Cloud, etc

– in the Cloud – available to use in WSO2’s managed cloud

– across the Cloud – bridging public and private clouds and

– under the Cloud – providing essential infrastructure to manage cloud systems

Multitenancy● A single instance of the software runs on a server,

serving multiple client organizations (tenants).

● Different from multi-instance architecture where separate software instances (or hardware systems) are set up for different tenants.

● A software application is designed to virtually partition its data and configuration so that each tenant works with a customized virtual application instance.

● Total data & business logic isolation is a fundamental requirement

Multitenancy - Advantages

● All advantages of *aaS– Automatic upgrades, bug fixes including security

fixes

– No infrastructure maintenance cost

– HA & scalability

– Overall cost saving● For the service provider: Cost of software &

hardware amortized over many customers● For the tenant: Small initial cost & monthly or

usage based payment

An Example: Multitenant Service Deployment & Dispatching

Autoscaling

● The Problem

– Fault tolerance, high availability & scalability are essential prerequisites for any enterprise application deployment

– High cost associated with achieving high availability & scalability.

– System throughput should not degrade under load

Autoscaling● The Solution

– Traditional solution● Buying safety-net capacity

– Better solution ● Scale-up the system when the load increases● Scale-down the system when the load

decreases● Should not have idling nodes● Pay only for the actual computing power &

bandwidth utilized● Cloud independent autoscaling

Analysis & Results

WSO2 Cloud Middleware Platform● Multitenant enabled middleware technology

that to support the WSO2 SOA Platform. ● A combination of the following middleware

aspects:– Data management

– Identity/security management

– Service hosting, mediation and management

– User interfaces and portals

– Billing and metering

– Management and monitoring

WSO2 Cloud Middleware Platform – Use cases

● Exposing internal services securely on the cloud

● Centralized management, control & monitoring of services using Cloud ESB

● Securely exposing data on the cloud using Cloud Data Services

– Mashing up content & secure data, and providing a dashboard

● Centralized governance on the cloud

● Centralized identity management on the cloud

Service Firewall Pattern

Secure Data Pattern

Example from Financial Domain Secure/private Data = Client Portfolios Public Data = Market Data

Cloud Identity – Identity As A Service
