Adaptability Resilience

Agility Cooperation

@eljuanchosf

Adaptability & AgilityA system should be able to respond quickly to change.

What brings change:

Humans using that system

Business model

Hardware

Software“The measure of intelligence is the ability to change.”

Albert Einstein

@eljuanchosf

ResilienceA system should be able to recover from failure.

What can go wrong?

Software instability

Physical failure

Attacks

Natural disaster“Our greatest glory is not in never falling but in rising every time we fall.”

Confucius

@eljuanchosf

CooperationA system should be able work together with other systems.

Why?

Specialization leads to either cooperation or isolation

Complex systems are made of simpler systems working together

“Coming together is a beginning; keeping together is progress; working together is success.”

Cloud Native

@eljuanchosf

An ever-changing group of methodologies and tools that allows software systems to be adaptable,

agile, resilient and cooperative.

Infrastructure as code

Platform as a Service

Containerization

12 factor apps

Continuous Integration & Delivery

Source control

Multi Data Center

Infrastructure as codeA way to manage and provision infrastructure from the ground up with a high level or descriptive language.

Terraform

Puppet

Chef

Ansible

BOSH

@eljuanchosf

Platform as a ServiceA way to develop, run and manage applications without going into the complexities of managing the underlying infrastructure.

Heroku

Amazon Elastic Beanstalk

Cloud Foundry (IBM Bluemix, Pivotal Web Services, GE Predix)

Google App Engine

OpenShift

@eljuanchosf

ContainerizationA technique of encapsulating applications in containers with its own operating environment, abstracting them from the operating system.

LXC

Docker

Rocket

Warden/Garden (Cloud Foundry)

@eljuanchosf

12 factor appsA methodology of writing applications that allows system and software architects, and developers, to create software that can run in the cloud seamlessly.

1. Codebase in revision

2. Declare dependencies

3. Config in environment

4. Backing services = attached resources

5. Separate build and run stages

6. Apps as stateless processes

7. Export services via port binding

8. Scale out via process model

9. Fast startup, graceful shutdown

10.Environments parity

11.Logs = events streams

12.Admin processes as tasks

If software is eating the world…

… don’t be the food.
