Cloud has almost completely replaced the old datacenters however still the teams are spending a lot of time and money on managing it.
Heroku solved the problem very well for years but it's very costly and limiting at the same time.
Now it's time to replace Heroku with services that help you use the cloud providers which leads to substantial cost savings.
We're very soon launching https://www.utopiops.com which is an alternative for Heroku on AWS to address this particular issue.
