Milkcocoa is a backend as a service (BaaS) that allows developers to build applications without having to maintain their own backend infrastructure. It provides simple APIs for storing and syncing data with real-time updates and authentication services. Developers can launch a backend with one click and implement functions like data storage, authentication, and real-time messaging using Milkcocoa's client SDK without having to manage servers, databases, or other backend components themselves.

2. Introduction
• I m Shuhei Hiya
• Founder of Technical Rockstars
• Study in Kyushu University in Japan
• How to develop apps more easier.

3. Agenda
• Intoroduction of our service milkcocoa
• Some technical topics about our service.

5. X as a Service
• IaaS (Amazon Web Service, Google Cloud Platform)
• PaaS (Heroku)
• BaaS(parse.com, Firebase)

6. Simple APIs to store and sync data.
Very low maintenance costs

7. Heavy Transaction Volume

8. A Backend Architecture
Database cluster
application server
load balancer

9. Application Architecture
• Backend and Frontend
• Backend
->Scale out, Security, Much Transaction
• Frontend
->Design,UI/UX

10. Need Experts Engineer

11. Browser
other
devices
mobile

12. Can implement function to store and sync
data with milkcocoa client SDK.
Need not to maintain.

14. Our Solution
Launch a backend by one click
developer Powerful API
• store data
• authanticate

16. Management View

18. Management View

19. var milkcocoa = new MilkCocoa("https://appid.mlkcca.com/");
var ds = milkcocoa.dataStore( message");
!
//observe the changes in real time
ds.on("push", function(data) {
alert(data.value.content);
});
!
//store data
ds.push({ content : "Hello!" });
Sample code of the simple chat.

25. Technical Topics

26. UseCase
• Web Site
• Campaign Site
• Mobile App
• IoT(various devices)

27. Backend Engineering
• Authantication
• Realtime Messaging

28. Authantication
• *Problem* there are many auth provider.
• Auth0 solved authentication problem. It use
JWT(JSON Web Token).
• JSON Web Token is important technology.It
make authentication more simpler. JSON data to be
transferred between two parties.

29. Identification providers
from https://auth0.com/

30. Real-time messaging
• WebSocket make us to use socket on
browser.
• MQTT is messaging protocol for IoT
devices.It decrease power/electricity
consumption.It supports Pub/Sub model
messaging.

31. Real-time messaging
• NodeJS has feature non-blocking io. But an
application run on one process basically.
• Erlang was designed by Ericsson. It s born for
telephony switches. It provides features for creating
and managing processes with aim of simplifying
concurrent programming.(from Wikipedia) Erlang
used in Whats Up,Line.

32. Conclusion
• https://mlkcca.com
• Some contents are Japanese Language.
• Develop application with combination of the
services such as Milkcocoa, Auth0, Algoria.
