![]() ![]() On top of that, getting locked into Heroku’s ecosystem also meant that Heroku could charge exorbitant costs - Woflow’s bill on Heroku started to increase exponentially as they added more dynos, which amounted to more than 10x the amount that the same computing resources would have cost on AWS. Securely connecting the two separate infrastructures on AWS SageMaker and Heroku within the same VPC was possible only by upgrading to Heroku Private Spaces, and even then it was challenging to keep low latency between the two infrastructures.This default autoscaling policy often resulted in over-provisioning of resources, which was worsened by the fact that autoscaling was only available on Performance tier dynos that are larger and more expensive. Autoscaling on Heroku relied on a metric that cannot be customized (i.e.It was impossible to install more than a few of these custom libraries because Heroku imposes a maximum image size limit of 500MB.Installing custom libraries, such as imagemagick, required them to write their own buildpack or rely on Heroku’s unofficial buildpacks that did not work very well.Below are few of the limitations they ran into: Woflow had started to run into these limitations as their stack evolved. The engineers at Woflow had zero visibility into the underlying infrastructure, which meant that there was no way to customize beyond the rigid guardrails that are set up by Heroku. As Woflow started to scale, however, they soon realized that Heroku is not a feasible long term solution due to vendor lock-in and rapidly increasing costs. In the beginning, Woflow set up their servers on Heroku and their ML infrastructure on AWS SageMaker. Porter allows Woflow to deliver these APIs at scale in a reliable way, while vastly simplifying the deployment process. ![]() Menu data is just one example - Woflow also helps companies in other industries, such as e-commerce or POS, turn unstructured data into a structured format in just a few seconds.įor a company like Woflow, robustness of their API is absolutely critical. With Woflow, delivery companies and merchants can instead make a simple API request to Woflow’s ML engine to automatically turn their menu into a fully digitized catalog. A different Heroku stack that is not currently supported by this repository may require changes to the build script in order to succesfully compile the binary file.Ever wondered how restaurants digitize their menus on delivery apps? You might think that restaurant owners manually enter each item on their menu into the app - well, that's how it used to be done. It will build ImageMagick with support to HEIC/HEIF based on the stack. The /scripts/build_imagemagick script is executed in the Docker image that was specified in Makefile. In the example above we use the Docker image heroku/heroku:20-build as well as passing the variable STACK as heroku-20 and the output binary file as .Ĭhoose the Docker image that suits your Stack and make the appropriate changes to Makefile. NOTE: To ensure the newer version of imagemagick is found in the $PATH and installed first make sure this buildpack is added to the top of the buildpack list or at "index 1".įrom your projects "Settings" tab add this buildpack to your app in the 1st run -v $(shell pwd):/buildpack -rm -it -e "STACK=heroku-20" -w /buildpack heroku/heroku:20-build scripts/build_imagemagick This buildpack currently supports Heroku 16 and Heroku 20 and contains ImageMagick 7.0.11-4 Q16 x86_64 Usage ![]() ![]() To build a new binary see How to Build a New Binary Versions You will need to build a new binary if you want to use a newer or different version. The tar file in the /build folder currently contains: The orginal buildpack was created for heroku-18 stacks but this one was modified to work with Heroku stack: heroku-16 and heroku-20. It is based on several resources including. This Heroku buildpack vendors a version of ImageMagick with HEIF support binaries into your project. The current default version of imagemagick installed on heroku:16 dynos is 6.8.9.9 and does not support processing heic image files. The rise in popularity and use of HEIF/HEIC(High Efficency Image Format) means your project's image processing also needs to be able to handle this format.
