Microservices Example
http://www.ibm.com/developerworks/cloud/library/cl-bluemix-microservices-in-action-part-1-trs/
Each tile is a microservice
“bookflights” interacts
with other microservices
Height corresponds to usage
Each microservice can be
Independently managed
à Shorter time to results and increased flexibility / scalability
à Replace small pieces instead of a complete application

“Cloud washing is the purposeful and sometimes deceptive
attempt by a vendor to rebrand an old product or service by
associating the buzzword ‘cloud’ with it [and offering it via a
public cloud infrastructure].”

12 (or 13, 14, …) Factor Apps for Cloud Native Microservices
Codebase
One codebase
tracked in
revision control,
many deploys.
Dependencies
Explicitly declare
and isolate
dependencies.
Config
Store config in
the environment.
Backing
Services
Treat backing
services as
attached
resources.
Build, Release,
Run
Strictly separate
build and run
stages.
Processes
Execute the app
as one or more
stateless
processes.
Port Binding
Export services
via port binding.
Concurrency
Scale out via the
process model.
Disposability
Maximize
robustness with
fast startup and
graceful
shutdown.
Dev / Prod
Parity
Keep dev,
staging, and
prod as similar as
possible.
Logs
Treat logs as
event streams.
Admin
Processes
Run
admin/mgmt
tasks as one-off
processes.

Why Containers?
http://www.slideshare.net/andersjanmyr/docker-the-future-of-devops
Containers enable:
• Lightweight deployment
• Automation
• Better resource utilization
• Scaling up and down quickly
• Platform agnostic deployment
• Innovation and Fail Fast Concepts
• Standardization ? Ø The Open Container Initiative (OCI)
Ø Docker Fork Discussions (!!!)

• Enterprises have to manage different clusters with different technologies
• Based on containers (but no specific technology, e.g. you can use Docker and rkt)

“The basic resource for CaaS is a container, rather than a virtual machine
(VM) or a bare metal hardware host system.”

Serverless Computing
• Bring a function (not an entire application) up for one single request.
• No cluster or server instance management.
• Small microservice-style functions running for a few (milli)seconds or at latest a few minutes.
• 100% utilization (!!!)
