13. Both speed and safety are required
Addressing customer needs faster, with less downtime retains your customers
Being able to make quick experiments (that aren’t destabilizing) gives you more chances at success
Protecting market share from disruptors or something unforeseen
People always say faster is better. Pivotal as a business because we think speed and safety is better together.
Cloud adds complexity, so safety is just as important as the speed derived:
-Less downtime might be the difference between a customer lost or retained. Similarly, experiments aimed at customer satisfaction are the same way – rolling out a new but slow mobile app doesn’t help you that much.
-Perhaps you’re the incumbent. When you debut your response to competitor’s disruptions, there is no room for outages or slow performance or the impact / impression you make is “me too” and not “this is the idea done right!” regardless of how cool the app is.
-If you’re the disruptor, your product better work – it might be all you have!
If your developers can go self service because your platform facilitates automated operations visibility, security and management, then you can increase your clock speed.
Head of platform at Springer Nature said publicly at our Berlin summit that Cloud Foundry “prevented 900 apps turning into 900 snowflakes”
The first to successfully rollout the innovation tends to win, defines the category

16. Loosely coupled service oriented architecture with bounded contexts
DEFINE: Microservice
If every service has to be updated in concert, it’s not loosely coupled!
Loosely coupled service oriented architecture with bounded contexts
If you have to know about surrounding services you don’t have a bounded context.
