So I had this

“brilliant” idea

for a talk….

So I wrote a

“brilliant”

presentation…

Then I listened to

a lot of brilliant

people…

• Many, many, more

the action of working with someone to produce or create

something.

traitorous cooperation with an enemy.

• Configurable Layers

• Reproducible

• Version-Controlled

The Flux Capacitor

Of Cloud Computing

Legacy - Node First Development

App +SO bundled machine images

Fragile, tightly couple apps and little resource fungability.

Low resource efficiency

Containers

Hermetically sealed deployment units

Efficient isolation and resource use.

ClusteringDeclarative app model

Agile, decoupled architecture

Smart (Machine Learning Enhanced)

Active Management

New World - Cluster First Development

Radically enhanced developer productivity: snap together systems.

Radically reduced operations overhead: deploy, run, update effortlessly

Operational specialization: cluster/infra ops separate from app ops

• Security???

• Binary Management (Repos)

• Resource tracking and separation

• Networking across clouds/hosts

• Container consistency (Multiple container sources)

• Many other problems with rapidly deployable, highly portable, easily used technologies

microservices(n) - Loosely coupled

service oriented architecture with

bounded contexts

If every service has to be

updated at the same time

it’s not loosely coupled

If you have to know

too much about surrounding

services you don’t have a bounded context.

• Microservices can be introduced quickly

• Leave old services in production until time to clean-up

• Allows for faster speed of innovation

• Code pushes are only additive so no legacy issues

Alex Williams (the New Stack) : Looking out at 2015, what are some of the issues that will be more complex in this distributed infrastructure world for customers – what are some of the top ones you see?

Mitchell Hashimoto(Hashicorp) - Number one is service proliferation, where your data center just becomes more and more services. Number two is, inherently becoming multi-data-center and highly-distributed at a much earlier stage. With things like Docker, where you can run things in much smaller units, it becomes a lot easier to start running a lot more services. As a result, we have a management problem, an orchestration problem, and distributed system problems in there.

Cloud 2.0

Where Awesome Starts

…the future of technological innovation is

not stealing limited resources away from

one another, but creating new resources

— and new opportunities to create new

resources — together in a rich ecosystem.

Open Source Isn’t a Zero-Sum Game

Innovate Develop what doesn’t exist to address your needs

LeverageLeverage the growing base of high-quality open source software

Commoditize Shift non-differentiating tech to reliable services or sources

Simon Wardley – Open Source as a weapon

• Declarative > Imperative – State desired results, let the system actuate

• Control loops: Observe, rectify, repeat

• Simple > complex: Do as little as possible

• Modularity: Components, interfaces & plugins

• Legacy compatible: Requiring apps to change is a non-starter

• Network-centeric – IP addresses are cheap

• Non grouping - Labels are the only groups

• Cattle > pets: Manager your workload in Bulk

• Open > closed: Open Source, standards, REST, JSON, etc.

A design pattern in which software/application components provide services to other software/application components via a protocol, typically over a network and in a loosely-coupled way.

SOA Definition circa 1995

• Massively Scalable

• Secure

• Competitive Prices

• Distributed Applications

• Proliferation of Microservices coming

• Cloud Tenets(Rapid Elasticity, Metered, Self-Service, Pooling, Broad Network)

• Hosted on User Selected Hardware

• Tailored to just what you need

• Unlikely to have as many zones as public

• Next evolution of cloud isn’t all-in-on, it’s federation of cloud services (no silos)

• Minimum Viable Cloud

• Network Quality of Service*

• Application Management *

• Service Level Differentiation*

• Developer Environments*

• Advanced Security*

• Continuous Integration*

• Developer Environments *
