5. What problems EU SMEs face?
5
Traditional market:
Legacy software systems
Customers with legacy
data now ask for Big
Data technologies
Growth in sight, but …
Learning curves
Initial prototyping
Risk of failure
(+ others…)
Fast-paced market

6. Traditional approach to deployment
o Spend time studying
documentation
o Use trial and error to set up
a working cluster
o Use incompatible public
cookbooks
o Repeat for each change
o Keep the Big Data cluster
fixed for fear of breaking it
days

7. What is in the box?
o DICER
 model your application
 create a TOSCA blueprint
o Cloudify
 Pure-play orchestration & automation
o DICE deployment tool
 alternative front-end for Cloudify
o TOSCA library
 worries about deploying Big Data
services so that you don’t have to

o Software market rapidly shifting to Big data
 27% compound annual growth rate through 2017 (IDC)
 Popular technologies such as Spark, Hadoop, and NoSQL
boost Big Data adoption and revenues from new services
Business issue: 65% of Big data projects still fail (CapGemini’15)

21. OASIS TOSCA
OASIS Topology and Orchestration Specification
for Cloud Applications

22. What is TOSCA?
o Open standard
o Enabling a unique Cloud
eco-system
o Supported by a large
and growing number of
international industry
leaders

Associated Companies

23. TOSCA is an Intent Model which is declarative
(integration points for imperative)
TOSCA Domain-Specific Language
Information Models
Typically, used to model a constrained
domain that can be described by a
closed set of entity types, properties,
relationships and operations.
Data Models
Typically, describe the structure
(format), enabling manipulation (via
interfaces) of the data stored in data
management systems assuring
integrity.
• Topology
• Composition
• Requirements - Capabilities
• State (Nodes, Relationships)
• Lifecycle (Management)
• Policy
Intent Model Adds:
• Structure
• Format
• interfaces
• Types, Relationships
• Properties
• Operations
 TOSCA can work with
imperative scripts
(e.g., Ansible, Chef,
Bash, Ant, etc.)
 TOSCA can include
other data models
(e.g., JSON, YANG)

24. Tier (Group Type)
TOSCA is used first and foremost to describe the topology of the deployment view for
cloud applications and services
Topology – Nodes and Relationships
24
source_resource
Node_Type_A
target_resource
Node_Type_B
Requirement
connect_relationship
ConnectsTo
Capability
Nodes - are the resources
or components that will be
materialized or consumed
in the deployment
topology
Relationships
express the dependencies
between the nodes (not the
traffic flow)
Requirement - Capability
Relationships can be
customized to match specific
source requirements to target
capabilities
Groups
Create Logical,
Management or Policy
groups (1 or more nodes)
 Node templates to describe components in the topology
structure
 Relationship templates to describe connections,
dependencies, deployment ordering

Cloudify Key Aspects
Open Source
Open source is key
to drive innovation
and create superb
quality software.
Open Standard
Open standard-based
TOSCA Spec for
application blueprints
allows vendor
neutrality, and
enables collaboration.
Future Proof
Try new emerging
technologies while
using stable in place
existing ones.

36. Deploy your own Big Data services
DevOps approach:
o Describe your Big Data
cluster and application in a
blueprint
o Store and maintain the
blueprint in your VCS with
the application’s code: IasC
o Rely on orchestrators and
configuration managers for
executing deployments

o DICE technology library simplifies blueprints
o TOSCA blueprints describe infrastructure as code
o Enabled Continuous Integration and Continuous
Delivery
