Our cloud
vision
• Activiti should help you to be in control of your
business and your cloud-native services

3. 2018

I’m already doing microservices…
• Why would I need Activiti?

4. 2018
Learn. Connect. Collaborate.
Does this resonate?

5. 2018
Learn. Connect. Collaborate.
Stronger together
• Scalable
• Intuitive
• Visible
• Manageable

6. 2018
Learn. Connect. Collaborate.
But how?
• Let’s get a better picture of this - an example
using our 7-201712-EA release
• Introduce key Activiti Cloud concepts and
illustrate how they can work for you

7. 2018
Learn. Connect. Collaborate.
Marketing Example
• Promote brands on Social Media (e.g. Twitter)
– Filter feed/s of content by relevance to brand
– Rank authors by relevance and sentiment of content to brands
• Periodically reward authors as incentive to post more

8. 2018
Learn. Connect. Collaborate.
BPM
Processes
- process that ranks
authors based on tweets
- process to reward
Campaign Feed and Ranking – instance per tweet
Campaign Rewards – initiated on timer

We made some BPMN – what’s our path to prod?
We designed some nice BPMN! Now how do we get an app to prod?
What do we normally do in the BPM world?

10. 2018
Learn. Connect. Collaborate.
Put it in a
BPM Suite?
• E.g. V6 kickstart or Alfresco Process Services
in Tomcat

11. 2018
Learn. Connect. Collaborate.
Use
embedded
engine?
• Maybe you ‘make jar not war’ e.g. activiti
spring boot starter

12. 2018
Learn. Connect. Collaborate.
Make cloud
not war!
• To do this with Activiti Cloud we’ll have
multiple smaller apps:
– Runtime bundle = scalable app that can
execute BPMN
– Connectors = apps that can implement service
tasks, talk to the runtime bundle (e.g. start
instances) and handle interactions with external
systems (e.g. twitter)
• These are new concepts we will demonstrate.
• Why all this new stuff?

13. 2018
Because we’re doing microservices!
Monolith
Microservices
Just one java classpath = monolith

14. 2018
Learn. Connect. Collaborate.
Why microservices?
• Because things fail – fault-tolerance
• Load-balancing
• Independent scaling
• Independent releasing
• Zero-downtime releases
• Etc.
• So what does it look like?

15. 2018
Learn. Connect. Collaborate.
-Runtime Bundle
-Twitter Connector
-Processing Connector
-Ranking Connector
-Reward Connector
Rewards Process
Handle Tweets

17. 2018
Learn. Connect. Collaborate.
Runtime Bundle
• Lightweight BPM executor
• Interfaces to other cloud components
• Independently scalable

18. 2018
Learn. Connect. Collaborate.
Cloud Connectors • Independently scalable
• Implementations of service tasks
• Interfaces to runtime bundles

Which looks
like…

examples/tree/develop/trending-topic-campaigns

20. 2018
Learn. Connect. Collaborate.
What do we do with it?
• Dockerize and then Kubernetes on AWS?
• Start listening to twitter?
• Alas, not at DevCon - this is an offline demo L
• We will use a fake twitter feed and run locally using
docker-compose and minikube

23. 2018
Learn. Connect. Collaborate.
What we didn’t talk about
• Activiti Cloud Query
• Activiti Cloud SSO IDM
