Back on August 11, 2016, Heroku experienced increased routing latency in the EU region of the common runtime. While the official follow-up report describes what happened and what we've done to avoid this in the future, we found the root cause to be puzzling enough to require a deep dive into Linux networking. The following is a write-up by SRE member Lex Neva (what's SRE?) and routing engineer Fred Hebert (now Heroku alumni) of an interesting Linux networking "gotcha" they discovered while working on incident 930. The Incident Our monitoring systems paged us about a rise in latency levels across…

This post is going to help save you money if you're running a Rails server. It starts like this: you write an app. Let's say you're building the next hyper-targeted blogging platform for medium length posts. When you login, you see a paginated list of all of the articles you've written. You have a Post model and maybe for to do tags, you have a Tag model, and for comments, you have a Comment model. You write your view so that it renders the posts: <% @posts.each do |post| %> <%= link_to(post, post.title) %> <%= teaser_for(post) %> <%= "#{post.comments.count} comments"…

We are happy to announce the general availability of Automated Certificate Management (ACM) for all paid Heroku dynos. With ACM, the cumbersome and costly process of provisioning and managing SSL certificates is replaced with a simple experience that is free for all paid Dynos on Heroku’s Common Runtime. Creating secure web applications has never been more important, and with ACM and the Let’s Encrypt project, never easier. ACM handles all aspects of SSL/TLS certificates for custom domains; you no longer have to purchase certificates, or worry about their expiration or renewal. ACM builds directly on our recent release of Heroku…
UPDATE: As of July 31, 2023, Salesforce no longer offers the Object Detection and Image Classification APIs. This means those APIs are no longer available. As a result, the demo app and the Einstein Vision add-on are no longer available. The most innovative apps augment our human senses, intuition, and logic with machine learning. Deep learning, modelled after the neural networks of the human brain, continues to grow as one of the most powerful types of machine learning. When applied to images, deep learning enables powerful computer vision features like visual search, product identification, and brand detection. Today, we bring…

Choices are an important part of a healthy open source software community. That’s why we’re excited about Yarn, a new package manager that addresses many of the problems with Node’s default package manager, npm. While npm has done a fantastic job creating a large and vibrant JavaScript ecosystem, I want to share why Yarn is an important addition to the Node.js ecosystem, how it will improve your Node.js development experience, and how Heroku has incorporated it into the build process for your Heroku apps. We began testing Yarn almost immediately after it was released, and began fully supporting it on…

Heroku bumped its Bundler version to 1.13.7 almost a month ago, and since then we've had a large number of support tickets opened, many a variant of the following: Your Ruby version is <X>, but your Gemfile specified <Y> I wanted to talk about why you might get this error while deploying to Heroku, and what you can do about it, along with some bonus features provided by the new Bundler version. Why? First off, why are you getting this error? On Heroku in our Ruby Version docs, we mention that you can use a Ruby directive in your Gemfile…
