It provides an easy way to deploy containers with ease of use.It has very good support from technical side as well which makes it more reliable than other providers I have used so far.The pricing structure can be confusing at some point but once you understand their plans it's fine overall.
We are using this tool mainly for CI/CD purpose where we want our builds to happen faster without any manual intervention or configuration change required by us (like creating build pipelines). This helps me automate my tests that were previously done manually before hand now they get automated automatically.
