A newly created environment receives a certain amount of cloudlets. Resource consumption depends on the type and quantity of your software stacks. Upon being added added to the environment, each stack receives the default number of allocated cloudlets according to the optimal resource amount, required for its proper workability.
|Node Name||Reserved||Scaling Limit|
If you would like to change these values and scale your environment, the maximum number of available resources (cloudlets) can be increased/decreased manually through the Environment topology wizard. For that, use the cloudlet sliders in the Vertical Scaling section of its central pane.
All the changes are applied immediately after they are saved, without the necessity to reload the virtual machine.
In order to be able to predict the approximate amount of resources your application will require and state the suitable scaling limits according to it, you can use the automatically gathered statistics
. It includes information about the consumption level during the last week for each node in your environment and displays it in a convenient graphic way.
And in the case your application becomes highly popular and a single server’s capacity is not enough, feel free to scale it horizontally by means of increasing the number of nodes manually
or configure a set of triggers for automatic horizontal scaling
of your application server.
