With our Virtuozzo PaaS almost everything is ready, just missing your application and you will be up and running in minutes, this is Platform as a Service.
Elastx responsibility is to make sure all platform services are fully operational and secure. We also upgrade the platform normally two times per year to add enhancements and new features.
Customer responsibility is to manage the application, the data and making sure there is enough resources (Cloudlets and storage) available. That also includes making sure adequate redundancy, backup (RTO and RPO) and to make sure the environment is protected with firewall. When running a VPS or your own Docker image the customer is also responsible for configuring and patching the operating system and all applications running on the node.
Here you can calculate how much your environment will cost. You have a start price, which is the minimum cost if your environment doesn't need to use any more resources and a maximum price.
