With the ease of deployment that SaaS services bring, most organizations are moving their infrastructure in the cloud. The ease of deployment can also lead to increasing costs if you do not plan ahead of time. Spinning up a new database for every new customer can easily be automated today, but down the line that would increase the hosting costs. At the same time, sharing customer data within a common database could result in leaking sensitive information across customers which could harm your re

Managing date and time fields has always been tricky. For customer engagement platforms, several of which are cloud-based and cater to customers globally, it’s especially imperative to accurately reflect the date and time no matter from which timezone a user logs in.

What happens when your application’s core S3 bucket is marked as dangerous by Google’s safe browsing feature and your web application is displayed as suspicious when accessed on Chrome/Firefox? We will talk about how we reacted to a similar incident that happened with us, and how we reduced the impact it had on our customers. We will also delve into design changes made to further reduce the impact of such events in the future.

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.
