Microservices

Containers

12-Factor Applications

Microservices are great, but they require:

rapid provisioningbasic monitoringrapid application deploymentdevops culture

Per Martin Fowler

Use declarative formats for setup automation, to minimize time and cost for new developers joining the project;Have a clean contract with the underlying OS, offering maximum portability between execution environments;Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration;Minimize divergence between development and production, enabling continuous deployment for maximum agility;And can scale up without significant changes to tooling, architecture, or development practices.

But even thats not enough

Role based access to resources: the right people should be able to do things and the wrong people shouldntRun specified bits on demand: take code, put it together with all the rest of the things it needs and and get it running Coordinate cross service configurations: in a service oriented world, services need to be configured to connect with each otherRoute public requests to running bits: the next big thing needs access to the internetRead and write persistent data: data has to live somewhereAdd and remove resources: scaling is a great problem to have, but still Isolate resources and failures without isolation and decoupling, that is one big distributed single point of failureMeasure performance/health: cant manage what you dont measureDetect and determine failure: sometimes, things get real but how do you knowRecover failures: someone is going to have to clean this messWork tomorrow: when everything youve thought to be true has been shown not to

Unit of ValueIaaS == Virtual MachineOpaque to the systemOrchestration is post-hocSystem changes are imperative (launch stuff)App Platform == ApplicationContainers are transparentLifecycle is fully managedSystem changes are declarative (manifest.yml)

VM is faster way to an operating system, application platorm is the application, not details about how its deployed, doing things in a declarative way

Platforms make promisesConstraints are the contract that allows a platform to keep promises

Wheres the container in this story?

Whats a container?Its isolation: name space, processfilesprocess - the command that targets the files to have a running processcflinuxfs2: root file system -> every droplet in CF starts life as a container thats started with default file system, user files are put on top of it, then build pack runs

Containers Are Awesome, but Not Enough

Were going to need a platform

Is BASH a platform?Is config mgmt with $YOURFAVTOOL?

Anatomy of a cf push (abridged)

start causes staging action (staging is some secret sauce)

Lets talk about Buildpacks / Staging Ruby code that detects language, frameworks, whatnotCompiles the code into executable binaries (*)

/bin/detect < Am I supposed to run?/bin/compile < Build the thing/bin/release < Pass along potential metadata

cflinuxfs2

Same as Herokus buildpacks.detect, compile, pull down executables, turn into binary3 scripts (detect, compile, release)

python scripts dont need to be turned into binary, but need dependencies

That was all about 12 factor apps

What about services?

Service Broker API, any implementation is fair Game5 operations:catalog - what it offerprovision - new servicebind - compine to service unpack with unbind and deprovision

The Cloud Native Advantage:

Simple PatternsHighly AutomatedScaled with Ease

A platform is a promise that the products will function in ways beyond whats written on the box; that the product is extensible and has value provided by an ecosystem bigger than the original vendor.

Horace Dediu, 2011http://www.asymco.com/2011/02/25/the-platform-as-a-promise/

Users see value

Were rebalancing the system towards user-driven roadmaps and control of the upstream project.

Were building support for specific industry clusters in Financial Services, Industrial IoT, and Telecommunications.
