Likelihood to Recommend Ambassador is really well suited for scenarios were you need to give power and freedom to your developers so they can take advantage of the self-service approach. One of the few scenarios I can not recommend using Ambassador is in the case you are planning to not using Kubernetes as it is a solution designed to work specifically on that platform
Read full review CircleCI is perfect for a CI/CD pipeline for an app using a standard build process. It'll take more work for a complex build process, but should still be up to the task unless you need a lot of integrations with other tools. If you have a big team and can spare someone to focus full time on just the CI/CD tools, maybe something like Jenkins is better, but if you're just looking to get your app built, tested, and delivered without a huge amount of effort, CircleCI is probably your preferred tool.
Read full review Pros Simple syntax Easy to understand Easy to install Read full review Multiple builds can be run at the same time in parallel. The CircleCI web interface (UI/UX) is very easy to understand and use. Easy Configuration to learn and use. Just a single configuration YAML file. Many integrations. We use the GItHub, Slack, and DataDog integrations. Read full review Cons Documentation is not updated Implementing external authentication doesn't always work as described in the documentation The Administration console is limited Read full review The "phases" their config file uses to separate out options seem very arbitrary and are not very helpful for organizing your config file No way that I know of to configure which version of MongoDB you use. You have to write your own shell script to download and start MongoDB if you want a specific version. Hard to access build artifacts in the UI Read full review Usability It's great! it's amazingly simple to use and the best part is the self-service approach. I also like how easy it is to add a new route to a endpoint with the mappings definition.
Read full review CircleCI interface is awesome in that it is relatively modern and makes it clear exactly which parts of the engineering lifecycle you are in
Read full review Performance It's pretty snappy, even with using workflows with multiple steps and different docker images. I've seen builds take a long time if it's really involved, but from what I can tell, it's still at least on par if not faster than other build tools.
Read full review Support Rating Overall the support has been great and quick to answer the requests I've submitted in the past. I was originally using the community/open source version and I can't say it was the best experience I had, it wasn't terrible but it wasn't great. I believe the biggest issue was that they refer to the documentation a lot but the documentation isn't updated regularly so I feel it's lagging behind the most recent versions.
Read full review Unless you have a reasonably large account, you're going to be mainly stuck reading their documentation. Which has improved somewhat over the years but is still extremely limited compared to a platform like Digital Ocean who invested in the documentation and a community to ensure it's kept up to date. If you can't find your answer there, you can be stuck.
Read full review Alternatives Considered They both offer about the same in terms of end goal and purpose of use and scenarios. However, Ambassador does way better in terms of simplifying the syntax and makes offer a little bit more of control by adding the concepts of hosts, mappings while staying away from a hard to read single file configuration.
Read full review Circle was the first CI with simple setup, great documentation, and tight integration with
GitHub . Using Jenkins was too much maintenance and overhead, TeamCity was limited in how we could customize it and run concurrent builds, TravisCI was not available for private repos when we switched.
Read full review Return on Investment Reduced downtime by redirecting traffic between DC. Reduced engineering time, don't have to dedicate 1 person to manage it. Increased training costs in the short term. Read full review It has eased the burden of standardizing our testing and deployment, making onboarding new developers much faster, and having to fix deployment mistakes much less often. It allows us to focus our process around the GitHub workflow, ignoring the details of whatever environment the thing we're working on is actually hosted in. This saves us time.
