Cloud Computing is about relationships

(But we focus on lists of things?)

The CLIPre-defined lists for all the things

● Availability Zones

● Baremetal Nodes

● Domains

● Flavors

● Floating IPs

● Host Aggregates

● Hypervisors

● Images

● Instances

● Key Pairs

● Metadata Definitions

● Networks

● Projects

● Routers

● Security Groups

● Subnets

● Volumes

● ...

The UIPre-defined lists for all the things

But a cloud is more like cake...Shopping List: A mix of things I care about

● Eggs

● Milk

● Flour

● Sugar

● Butter

● Chocolate

● Baking Powder

Cake: Specific relationships of the things

Managing CloudsIs managing relationships

between things

Add a network to this instance

Create a Volume based on this Image

and attach it to this Instance

Find all the Floating IPs in-use by this

Managing relationships from predefined lists is hard

List of things

Details of one thing

List of things

And it's hard to connect the dots in pre-defined listsScale Targets::

● 12,000 instances

● 300 hosts

● 256 users

● 512 projects

● 512 images

● 256 flavors

● 14,400 IP addresses

● 7,000 floating IPs

● 5120 Security Group Rules

● 16,000 Volumes

Navigating the relationships you care about

becomes hard in a pre-defined list:

● Find everything tagged with “web"

● Power off all of Bob’s instances

● Find all IPs in this subnet

● List all projects with access to this image

● Display any flavor using this Metadata

CloudRequiresSearch

Build a custom list of

related things

“Where can I find Bob?”

Find all the related, but different things and act on them

View the basic details in-line

Drill down for more...

Dive further into related details...

But always be able to return back to your current search

Horizon is a GUITherefore everyone has a different

opinion

We don’t have to agree

on the navigation

on the contents of the dashboards

If the UI knows:

● which actions are possible for a

given resource

● which views are available for a

resource

● how to display a given action or

Free The Actions!And the views!

Today, business logic is tightly bound

to one “generic” view of the world.

● All views for a resource are

hardcoded to a panel dedicated

to that resource.

● All actions for a resource are

hardcoded to that dedicated

Use a Resource Type Registry

to link each kind of resource with

its actions and views

registration = {type: OS::Glance::Image,actions: [ create, update,…]views: [ details, drawer,...]

It becomes much cheaper to build

● a search oriented view

● a task oriented view

● a custom dashboard

● a new-hotness

Horizon becomes Composable

Rearrange resource lists, details

and actions

Build a Search Based UI

Build a Navigation Based UI

Choose your favorite arrangement of actions and views

Unified Searchwe don’t all have to implement it

we also don’t have to re-invent it

OpenStack is a set of distributed services

● distinct responsibilities

● different project teams

● many layers of code

● SQL databases

● operate the cloud

● fulfill end user requests

SearchlightElasticSearch

injected with OpenStack

● elasticsearch query API

● sensible results for simple queries

● allows very specific queries

● adds role-based access control

Powerfulwe just need to feed it the data

● full text search

● search term discovery

● auto completion

● fuzzy search

● consistent pagination

● geo-spatial search

○ Cinder volumes, snapshots

○ Neutron networks, ports, subnets, routers

○ Designate (DNS) Zones, recordsets

Improvethe

Notificationsavoid api callbacks

Notifications in OpenStack are spotty

● missing events

● missing data

Search Needs Client Side

HorizonBecause search is interactive

This gives focus and purpose to the

effort to “Angularize” Horizon.

● users are constantly changing

views to manage relationships

● changing views client-side is

● when I can find any related

thing...and take immediate

action, my experience is FAST
