Measuring Value

• Time

• Cost

• Resources

What is your value baseline?

Running a Cloud Business

Measuring Revenue versus Cost

Increasing Value: Cloud Objectives

• Financial Value

• Shift from capital expense into operational expense

• Pay only for what you use

• Efficiency Value

• Right-size solution footprint to match demand

• Pool resources and increase utilization

• Agility Value

• Reduce time to market through DevOps, automated governance, and on-

demand services

Cloud Business Value Blockers

• Silo owners

• Adoption curve

• Trust barrier

• Unknown baseline

• Funding model

Overcoming Cloud Value Blockers: WSO2 AppFactory

Architecture Shapes Value

• Resource friendly := small footprint, minimal consumption,

parallelizable workloads

• Poolablility := Non-exclusive use, short usage duration

• Automation := decrease activity time, latency between steps

• Governance := encourage trust, communication, coordination

• Distribution friendly:= Stateless, autonomous

PaaS Architecture What is a partition?

• Partitions define distinct container resource pools

• Partition containers to tune container sharing, service resource

allocation, QoS, and utilization

• Containers may be assigned into service-specific or tenant

specific partitions

Partitions modify value proposition

Single, flat namespace Multiple partitions and segmented name space

Tenant Scaling Method Impacts Value Proposition

Single Application Tenant

per

Dedicated Application

Server Container

Multiple Application Tenants per

Shared Application Platform Service Container

Container Tenancy Implications

• Traditional application servers can host multiple applications,

but resource isolation limitations may restrict sharing • Common limitations: code deployment, security, administration

• Implication • 1 application server per tenant

• (N) application server license per (N) tenants

• (N) IaaS node per (N) tenant

• Multi-tenant application servers can host multiple tenant

applications with appropriate resource isolation • Limitations overcome by:

• OSGI class loading, custom security manager, Cloud aware code deployer,

tenant-aware administration screens

• 1 application server per N (~7-100) tenants

• 1 application server license per N tenants

Key Value Metrics

• Foundation

• Time to create new application environment

• Time to redeploy application

• Optimize

• Minimum and maximum scale

• Scale frequency (i.e. time to scale up/down)

• Transformation

• Time and effort required integrating business process, event

processor – creating a complex app.

• Time and effort required to apply policy across tenant(s)

• Cost to operate application per user or transaction
