Conclusions

• Organizations can no longer rely on long lasting competitive advantage to stay alive and profit. In an era of “transient advantage,” they must continually seek new business models and evolve existing ones.

• IT does not generally operate in the agile, small batch, “cloud native” ways that are required to be software defined businesses.

• The broad technologies are continuous delivery (the why), microservices (the what), and DevOps (the how).

• A “cloud platform” provides all of the development and operational capabilities needed to be cloud native.

• You can build and maintain your own platform (plus the original application you wanted!) or use a ready-made cloud platform

“If advantages eventually disappear, it only makes sense to have a process for filling your pipeline with new ones. This in turn means that, rather than being an on-again, off-again mishmash of projects, your innovation process needs to be carefully orchestrated.”- Prof. Rita McGrath, “Transient Advantage,” HBR, June 2013

“Cloud Native” is IT’s answer to transient advantage

Cloud Native Business Theory

(1.) In an era of transient advantage, the inherit agility of software is one of the best strategic tools.

(2.) However, software in large organizations does not currently “work like that.”

(3.) The fix is changing how we think of the process of software, supported by cloud native technologies & practices.

The Process

Discovering & delivering the software your customer actually wants

• Most organizations emphasize building to plan

• In reality, the “plan” constantly evolves

• Learning organizations explore & experiment

How most businesses think they’re doing

How smart businesses know they’re doing

- Reduced risk of delivering the wrong thing- Frequent feedback increases design quality, innovation- Increased visibility & controls for finance & GRC

Go big with small batches

• Vitality drove engagement from 3% to 30%+

• Cue Apple Watch app: “Two people built the app and got it into the AppStore in five weeks.”

"We did an analysis of hundreds of projects over a multi-year period. The ones that delivered in less than a quarter succeeded about 80% of the time, while the ones that lasted more than a year failed at about the same rate. We're simply not very good at large efforts.”

Continuous DeliveryRelease once every 6 months

More Bugs in production

Release early and oftenHigher Quality of Code

DevOpsNot my problem

Separate tools, varied incentives, opaque process

Shared responsibilityCommon incentives, tools, process and

culture

MicroservicesTightly coupled components

Slow deployment cycles waiting on integrated tests teams

A cloud native platform is composed of three layers, that span & support the entire life-cycle of an application from development to production
