Cloud Computing in Asia Pacific – Architecting For The Future

Cloud Computing Gartner defines cloud computing as "a style of computing where scalable and elastic IT-related capabilities are provided 'as a service' to customers using Internet technologies."

The value of a cloud computing service is in

the outcomes it enables, just as the

value of a treadmill is in building heart health

or losing weight.

Use of Cloud Services from ESPs - Future

Example – Japanese Public Sector

• Massive (24,000 branches) national organization facing privatization and breakup.

- Needed to streamline processes across three companies covering 75,000 users and 25,000 concurrent requests

- Minimimize technology footprint

• One of the largest PaaS implementations in the world • Relatively high user satisfaction with functionality and agility of the

system.

• No performance or security issues so far.

• Process insight was a big result

Example – Australian University

• iPortfolio – Personal Learning Space

- Track performance against degree requirements

- Create personal profile similar to social sites

• Use of Cloud Computing

- Reconcile cost and agility of required storage overhead

• Open up great possibilities in types of data, i.e. video

- Reduced the complexity of ongoing improvement

- Forming the basis of a more substantial consideration of cloud across the organization

Policy or process for consuming cloud services from ESPs

Action Item: Develop a Cloud Strategy for Public, Private, AND Hybrid Cloud as Appropriate

Through 2012, IT organizations will spend more money on private cloud computing investments than on offerings from public cloud providers.

Choose public if …

• There is a cost benefit.

• Service-level guarantees and security meet all requirements.

• All legal/data ownership and compliance requirements are met.

• Failure remediation/disaster recovery (including provider failure) is proven.

Choose or build private when …

• Public cloud fails to meet needs.

Best Practice: Innovate by Loosening Dependencies (Service Orientation)

Many-to-One-to-Many

Interface

Change easier; loose dependencies

Change hard; app and infrastructure

at same time

Service Consumers

More critical new technologies to watch for and standardize long term

Truly loose coupling between provider and consumer equals tightly coupling both to a general, stable interface in the middle.

Change still difficult; dependencies strong

Impact Can Be Positive or Negative: Learn From Notable Cloud Outages

• Design for failure at IaaS layer:

- Provider-specific

- Requires transparency

• Design for resiliency at application layer:

- Need access to code

- Significant investment required in architecture

- Requires high-control application platform or evaluation of high-productivity provider's design

• Reduce risk in other non-technical ways:

- Financial

- Insurance

• Trust your provider, but verify

By 2015, 20% of non-IT Global 500 companies will be cloud service providers

Cloud Security Affects Your Planning…

• Security assessment difficulties

- Adequate information is hard to obtain.

• Data compromise risk

- Encryption is a partial solution to privacy issues.

• Data loss risk

- How do you back up a cloud service?

• Vendor viability and data portability concerns

- Open-cloud portability standards still immature.

• What are your "cloud rights"?

- IP, ownership, recovery, continuity?

Litigate?

Trust

Protect

• Contract negotiations start with the assumption that the consumer has rights.

• Should provider rights override consumer rights?
