We recently launched Apache Kafka on Heroku into beta. Just like we do with Heroku Postgres, our internal engineering teams have been using our Kafka service to power a number of our internal systems. The Big Idea The Heroku platform comprises a large number of independent services. Traditionally we’ve used HTTP calls to communicate between these services. While this approach is simple to implement and easy to reason about, it has a number of drawbacks. Synchronous calls mean that the top-level request time will be gated by the slowest backend component. Also, internal API calls create tight point-to-point couplings between…

With the Salesforce hackathon fast approaching, I wanted to give a quick overview on building apps that use the force.com APIs (part of the Salesforce1 platform). The force APIs are rich and varied, so sometimes just getting started can seem a little daunting. What services are provided? The force.com APIs give your application access to the authentication, data storage, and business rule services provided by the Salesforce1 platform. Some of the things you can do with the APIs include: Authenticate users based on a Salesforce username and password Query any data stored in a Salesforce account. Data access rules for…

One of the challenges when starting a mobile app project is deciding what technology stack to use. Should the client app use iOS or Android native, mobile web, or a hybrid? Do the backend in Node, Ruby, or Java? Or skip the backend and use an Mobile Backend-as-a-Service? To help avoid needing to answer all those on your own we are open sourcing the Heroku Mobile Template. This app provides a full-stack starting point for creating new hybrid mobile apps and deploying them to Heroku. What’s in the box? The template application implements a simple real-time mobile Quiz app called…

Heroku Connect is a service offered by Heroku which performs 2-way data synchronization between Salesforce and a Heroku Postgres database. When we first built Heroku Connect, we decided to use polling to determine when data had changed on either side. Polling isn't pretty, but its simple and reliable, and those are "top line" features for Heroku Connect. But polling incurs two significant costs: high latency and wasted resources. The more you poll the more you waste API calls and database queries checking when there are no data changes. But if you lengthen your polling interval then you grow the latency…

Force.com and Heroku are both part of the Salesforce1 platform. There are lots of great ways to leverage force.com from your Heroku app. This article will give an overview and pointers to get you started. Heroku Connect The easiest way to link force.com and Heroku is to use our two-way data synchronization service Heroku Connect. This point-and-click service lets you synchronize data from force.com into the Postgres database attached to your Heroku app. You can read and write data directly in Postgres, and changes are automatically synchronized with force.com. Note that Heroku Connect moves data asynchronously. This means that when…
