Image uploading can be complex, and use-cases vary depending on the system. There’s a lot of concerns with images in general that most people don’t think of when they are diving into building it out.

Feature Toggles (often also refered to as Feature Flags) are a powerful technique, allowing teams to modify system behavior without changing code. They fall into various usage categories, and it's important to take that categorization into account when implementing and managing toggles. Toggles introduce complexity. We can keep that complexity in check by using smart toggle implementation practices and appropriate tools to manage our toggle configuration, but we should also aim to constrain the

In distributed systems, retries are inevitable. From network errors to replication issues and even outages in downstream dependencies, services operating at a massive scale must be prepared to encounter, identify, and handle failure as gracefully as possible.

A Workflow is a series of decisions made by different people that determines what happens to a particular request that one of those people made, according to a defined and repeatable process. An example of this process is shown in this flowchart.

The core components of this architecture are a web front end that serves client requests, and a worker that performs resource-intensive tasks, long-running workflows, or batch jobs. The web front end communicates with the worker through a message queue.

By sharing what we do (and I mean all of us), we better our world. Everyone that works at Stack shares at least one passion: improving life for all developers. Sharing how we do things is one of the best and biggest ways we can do that. It helps you. It helps me. It helps all of us.
