CircleCI

We use CircleCI as our centralised Continuous Delivery engine for our platform. It orchestrates the entire application lifecycle, from code commit to deployment, across our distinct environments and two major platforms (Web and Mobile). It addresses the following Business Problems: 1. CircleCI eliminates our Environment Inconsistency, by automated builds in isolated Docker environments that ensure code behaves identically in production as it does during our development. 2. CircleCI accelerates our Mobile releases by automating the complex build-and-sign process for iOS and Android with Fastlane, and we significantly reduce manual effort and time-to-market for mobile updates. 3. CircleCI enhances our security & compliance by integrating Snyk scans automatically, which allows us to detect vulnerabilities in dependencies and containers before deployment, ensuring every release meets security standards. 4. CircleCI helps us in mitigating our Production risks by implementing manual approval gates, which prevent accidental deployments, giving our team control and confidence in update rollouts.

• Faster Releases - since our deployment is automated, our releases are faster, enabling us to deliver new features or bug fixes to our customers quickly, improving our customer ratings.
• No need for a large infra team to manage deployments. Since our deployments are automated with CircleCI, we have a leaner infrastructure team, which reduces costs.
• No need to teach any developers about deployments. Since builds and deployments are automated, developers can focus solely on development without worrying about deploying to the testing or production environments. This allows us to build more features faster.

• Simple continuous integration for every branch before merging for safety.
• Simple continuous deployments means better velocity.

Travis CI and Jenkins

Heroku Platform, Algolia, Node

We use CircleCI for continuous integration and delivery of our mobile app. The main users are our DevOps team to help manage code releases. It's helped us push code to production with a standardize process and can now ensure we get a build with each merge. Our codebase is ReactNative and run on AWS CloudFront.

• scalability
• github integration
• easy to use ui

• less devOps staff needed to manage builds
• lower investment to create build process
• some dev cost in debugging when builds fail but less than if we had a custom solution

• Positive: Circle helped us to make a fast release process of our native based application and reduced our time to market.
• Positive: Circle helps us avoiding the time and money maintenance cost of a release process system.
• Negative: The cost per user and billing it per month make it a bit difficult to make the payments on time if you are working in a big company with a lot of payment processes.

• Greatly increase the speed of code delivery. We no longer need to go through a long deployment process for every feature. Developers can spin up their dev environments at will, test new features, and verify their code is ready to ship in just minutes.
• Reduced labor. Again, no more long, manual code deployments. And this means big savings in labor costs.
• Code quality. Since CircleCI runs various tests after building, we know if a code change broke a feature immediately. It can be fixed before the feature is even scheduled for release to production.
