Tarantool Cloud is a service that allows you to run a self-healing, replicated set of tarantool instances. It is built on top of Consul and is resilient to some of the typical hardware and network problems.
It provides the following key features:
- REST API: for programmatic creation and destruction of tarantool instances
- WEB UI: to allow human agents create single on-demand instances and get an overview of the system
- Failover: to automatically recover from node failures or degraded storage

To prepare an environment, do:
docker-compose upThen go to http://localhost:5061 to access web UI.
Note: first-time creation and launch of tarantool instances may take a long time, as the instance manager is building docker images.
./taas -H localhost:5061 run --name myinstance 0.3This will create an instance named myinstance, with 0.3 GiB memory limit and return its ID.
./taas -H localhost:5061 psIt will produce output like this:
