Agenda

• What are microservices anyway?

• Pattern 1 – The Gateway

• Pattern 2 – Synchronous Broker

• Pattern 3 – Asynchronous Broker

• Microservices on Salesforce1

• Summary

• Q&A

What are microservices anyway?

Break the MonolithBusiness Capabilities – Products not Projects

CommunicationRESTful or Message Queues?

• We will be showing our microservices communicating over a message queue

• REST is most common pattern for synchronous communication

• Message Queues for asynchronous

• We are showing a message queue because:

• Lots of people may not have seen one

• Salesforce REST API would be better for REST based microservices architecture

Pattern 1 - The Gateway

Pattern 1 – The Gateway

1. Microservice processes some information that requires interaction with Salesforce

2. Microservice places message for Salesforce Gateway Microservice on message queue

3. Gateway Microservice handles message from queue and calls appropriate function(s)

4. Gateway Microservice functions call out to Salesforce REST API

5. Salesforce REST API returns response

6. Gateway Microservice handles and processes response as well as acknowledging processing of

message

7. Acknowledgement (possibly including processed REST API response) routed handled by

originating microservice

8. During processing, Gateway Microservice may place another message on queue to be handled by

other microservices

The Microservice Part

The Gateway and SFDC Part

Pattern 2 – Salesforce Broker

Synchrnous

Pattern 2 – Salesforce Broker (Synchronous)

Pattern 2 – Salesforce Broker Synchronous

1. Microservice processes some information that requires interaction with Salesforce

2. Microservice places message for Salesforce Broker Microservice on message queue

3. Broker Microservice handles message from queue

4. Broker Microservice calls custom Broker Apex REST Endpoint

5. Apex REST endpoint handles message and calls required apex code for message

6. Broker endpoint responds with output from routed message

7. Broker Microservice receives response and routes back to originating microservice via

acknowledgement

8. Acknowledgement (including Salesforce API response) handled by originating microservice

Microservice Posts to a Queue

Broker Microservice Passes Information Through

Pattern 3 – Salesforce Broker

Asynchronous

Pattern 3 – Salesforce Broker (Asynchronous)

Microservices on Salesforce1Doing it on the platform

Microservices on Salesforce1

• Salesforce can be a first class player in a microservice architecture

• Your situation will dictate the best pattern(s) to apply

• Adoption takes time

• Code samples and information available at: http://some.url.com

• We would love your feedback

• On the session

• On how you are (or could be!) using microservices
