Main Trends

DevOps Cloud

Network Function

Virtualization (NFV)

IT-as-a-Service

Big Data processing

Use Case #1 -‐ DevOps Cloud

Environment for developers to create, test and publish applications

Environment includes development tools and possibly common application components

Use existing or DIY PaaS platform -‐ Cloud Foundry, OpenShift, Appcara etc.

Even Simple Systems Exhibit Complex Behaviors

Xn+1 = rXn (1-Xn)

Even a simple logistic system results in complex outcomes

Large Distr ibuted Systems are Complex


How to Handle Complexity?


Is there an easier way?

OpenStack exposes infrastructure resources

so they can be controlledprogrammatically

→Compute

→Network

→Persistent Storage

→Ephemeral Caching

→Auth/Access

→Monitor/Logs/Audit

→OS-‐Image/Virtualization

→User Credentials

Each app “can” specify its own infrastructure...



Every programmable resource has a potentially independent revisioncycle.

Application’s internal configuration

… but each app also becomes a snowflake*

APPLICATION/WORKLOAD/SERVICE

Network switch and routing

Persistent Storage

OperatingSystemImage

East/West authentication access/control

Ephemeral(cache) Storage

Monitoring Logging

User credentials

*snowflake -‐-‐ unique configuration, difficult to manage consistently

Application Workload

Get, Share and Run Apps on Demand

Create Catalog● Easily add new apps● Describe forms, app

dependencies, suggested configurations, billing rules etc.

Deploy Apps● Deploy applications and services

with a push of a button● Choose apps, specify settings,

and deploy

Automatically Manage Apps

● Monitor with Ceilometer● Automatically self-heal, scale

up & down, failover, backup● Application specific actions● Track usage

Declarative Approaches to Simplify

Enable operators to control the end state of the cloud



Local cloud dependencies

● Networks● Security groups● Availability zones● Roles● Storage● Backup software...

Result: versions of templates for every deployment environment

How can the developer define?

● Deploy● Upgrade● Scale● Backup/restore


For every deployment environment?

The developer shouldn’t care at all about the deployed environment.


Developer Def ines Gener ic Lifecycle


Define the basic steps for each lifecycle events using a simple workflow language

Object oriented to define events with inputs

● deploy, upgrade, scale, backup, restore, etc…

Murano partitions OpenStack cloud app/service lifecycle mgt.

1. Catalog users:Launch apps/services independent of infra dependencies

2. Catalog Application/Service developersSpecify apps’ infra needs, no direct binding of resources

3. Cloud administratorsConfigure and control apps for automation for deployment, operations for OpenStack cloudapps/workloads

Murano delivers apps/services to OpenStack faster

How do developers start working with Murano?

1. Glance2. Heat Templates3. Murano Packages

Glance images – 3 words “Disk Image Builder”

Drop it like it’s HOT – Heat Orchestration Templates

Murano – Ingredients

• YAML definitions of assets• Javascript site to display• New content/assets flow

through the OpenStackCommunity Process

• Cosumable via Horizon or an OpenStack API

Cloud Operator


Refine the UI to only ask for needed input

https://murano.readthedocs.org/en/stable-‐kilo/articles/dynamic_ui.html

“The main purpose of Dynamic UI is to generate application creation forms “on-‐the-‐fly”. Murano dashboard doesn’t know anything about what applications can be deployed and which web form are needed to create application instance. So all application definitions should contain a yaml file which tells dashboard how to create an application and what validations are to be applied.”
