Salesforce: Outbound Messaging
Scalable Salesforce Integrations on a Shoestring Budget – Giuseppe Cardace, Sébastien Virtel - Dreamforce ‘19
 Declarative: Admins can configure it
 Contract-First: Uses WSDL, SOAP & XML
 Sends asynchronous notifications from
workflow rules or approval processes
 Bulkified: up to 100 notifications /msg
 Automatic retries for 24 hours
 Monitoring tool
 Independent retries:
Message order not guaranteed
 Because a message may be delivered
more than once, your listener client
should check the notification IDs
delivered in the notification before
processing.
 Since it’s Workflow-based, it’s limited
to Inserts and Updates
Benefits Concerns / Tradeoffs

18.
AWS: API Gateway
 Declarative or Programmatic
 Integrates with other services, e.g.:
• run AWS Lambda
• pass payload to SQS, SNS, etc.
• start AWS Step Functions
 Autoscale & Configurable Resiliency
 Authentication
 Optimized for REST services with JSON
payloads
 Workaround: wrap SOAP XML message
as a String into a JSON object
Scalable Salesforce Integrations on a Shoestring Budget – Giuseppe Cardace, Sébastien Virtel - Dreamforce ‘19
Benefits Concerns / Tradeoffs

19.
AWS: SQS - “Standard”
 At-Least-Once Delivery (Standard):
A message is delivered at least once, but
occasionally more than one copy of a
message is delivered.
 Best-effort ordering (Standard):
Queue triggers are not supported by FIFO
queues
 Message size: max 256 KB/message
(invoiced in 64 KB-chunks)
→ Save by message bulkification
Standard Queue with Triggers
Scalable Salesforce Integrations on a Shoestring Budget – Giuseppe Cardace, Sébastien Virtel - Dreamforce ‘19
 Declarative or Programmatic
 Configurable retention period:
default 4 days [1 min to 14 days]
 Unlimited Throughput (Standard)
 No upfront costs → Pay per use
 Server Side Encryption
 Dead Letter Queues (DLQ)
Benefits Concerns / Tradeoffs

20.
AWS: Lambda
 Requires some coding skills
� Save implementation and maintenance
time by using some graphical tool that
generates robust code!
Serverless compute
Scalable Salesforce Integrations on a Shoestring Budget – Giuseppe Cardace, Sébastien Virtel - Dreamforce ‘19
 Auto-scaled serverless functions
 Built-in multi AZ fault tolerance:
no maintenance windows or downtimes
 No upfront costs → charged by 100ms
 Reuse: pass Context in Env variables
 Flexible resources: config memory &
timeout period→ proportional CPU,
network, disk I/O
Benefits Concerns / Tradeoffs

21.
«Write» your code faster
 Free, open source, Apache license
 Graphical design environment
(Eclipse-based)
 Hundreds of connectors: Salesforce, SAP,
Marketo, Oracle, MS SQL server,
PostgreSQL, MySQL, AWS, Azure,
Dropbox, Box, SMTP, FTP/SFTP, etc.
 File management: open, move, zip
 Control and orchestrate data flows
 Map, aggregate, sort, enrich, and merge
data
 The executable JAR produced by
Talend cannot run as-is in AWS
Lambda
 Use Amazon SDK in a small wrapper
Java application; add the JAR to the
build path and execute the Talend job’s
runJob method

AWS: RDS PostgreSQL
 Requires some PostgreSQL-specific
knowledge to create users, tables,
views, triggers, and especially
configure row-level security policies
Serverless Database
Scalable Salesforce Integrations on a Shoestring Budget – Giuseppe Cardace, Sébastien Virtel - Dreamforce ‘19
 Fault-tolerant: Multi-AZ deployments with
automatic switch in case of issues
 Automatic software patching
 Scalable:
• Push-button compute scaling:
up to 32 vCPUs and 244 GiB RAM
• Easy storage scaling: no downtimes
Benefits Concerns / Tradeoffs

26.
AWS: CloudWatch (Logs & Monitoring)
Unified Log Collection and Analysis
Scalable Salesforce Integrations on a Shoestring Budget – Giuseppe Cardace, Sébastien Virtel - Dreamforce ‘19
 Custom Log Retention Periods
by service and lambda function
 Built-In Metrics for the main services
 Set Alert thresholds on key metrics
 Create your own dashboards!
