Here we have to look at all the other Instances on the host to compute our cost.

Derived classes are used to select which host filtering and weighing strategy will be used. Filtering and Weighing ------------- +---------------------- The filtering (excluding compute nodes incapable of fulfilling the request) and weighing (computing the relative "fitness" of a compute node to fulfill the request) rules used are very subjective operations ... Service Providers will probably have a very different set of filtering and weighing rules than private cloud administrators. The filtering and weighing aspects of the `ZoneAwareScheduler` are flexible and extensible. + .. image:: /images/filtering.png + Requesting a new instance ------------- +------------------------- Prior to the `ZoneAwareScheduler`, to request a new instance, a call was made to `nova.compute.api.create()`. The type of instance created depended on the value of the `InstanceType` record being passed in. The `InstanceType` determined the amount of disk, CPU, RAM and network required for the instance. Administrators can add new `InstanceType` records to suit their needs. For more complicated instance requests we need to go beyond the default fields in the `InstanceType` table. `nova.compute.api.create()` performed the following actions: -1. it validated all the fields passed into it. -2. it created an entry in the `Instance` table for each instance requested -3. it put one `run_instance` message in the scheduler queue for each instance requested -4. the schedulers picked off the messages and decided which compute node should handle the request. -5. the `run_instance` message was forwarded to the compute node for processing and the instance is created. -6. it returned a list of dicts representing each of the `Instance` records (even if the instance has not been activated yet).

At least the `instance_ids` are valid. + + .. image:: /images/nova.compute.api.create.png Generally, the standard schedulers (like `ChanceScheduler` and `AvailabilityZoneScheduler`) only operate in the current Zone. They have no concept of child Zones. The problem with this approach is each request is scattered amongst each of the schedulers. If we are asking for 1000 instances, each scheduler gets the requests one-at-a-time. There is no possability of optimizing the requests to take into account all 1000 instances as a group. We call this Single-Shot vs. All-at-Once. For the `ZoneAwareScheduler` we need to use the All-at-Once approach. We need to consider all the hosts across all the Zones before deciding where they should reside. In order to handle this we have a new method `nova.compute.api.create_all_at_once()`. This method does things a little differently: -1. it validates all the fields passed into it. -2. it creates a single `reservation_id` for all of instances created. This is a UUID. -3. it creates a single `run_instance` request in the scheduler queue -4. a scheduler picks the message off the queue and works on it. -5. the scheduler sends off an OS API `POST /zones/select` command to each child Zone. The `BODY` payload of the call contains the `request_spec`. -6. the child Zones use the `request_spec` to compute a weighted list for each instance requested. No attempt to actually create an instance is done at this point.

Zones are expected to operate in complete isolation from each other. Each Zone has its own AMQP service, database and set of Nova services. But, for security reasons Zones should never leak information about the architectural layout internally. That means Zones cannot leak information about hostnames or service IP addresses outside of its world. -When `POST /zones/select` is called to estimate which compute node to use, time passes until the `POST /servers` call is issued. If we only passed the weight back from the `select` we would have to re-compute the appropriate compute node for the create command ... and we could end up with a different host. Somehow we need to remember the results of our computations and pass them outside of the Zone. Now, we could store this information in the local database and return a reference to it, but remember that the vast majority of weights are going be ignored. Storing them in the database would result in a flood of disk access and then we have to clean up all these entries periodically.

We encrypt all the child zone internal details and pass them back the to parent Zone. If the parent zone decides to use a child Zone for the instance it simply passes the encrypted data back to the child during the `POST /servers` call as an extra parameter. The child Zone can then decrypt the hint and go directly to the Compute node previously selected. If the estimate isn't used, it is simply discarded by the parent.

Since Nova is currently dependent on the `InstanceType` structure, the `instance_type_to_filter` method should take an `InstanceType` and turn it into an internal data structure usable by your filter. This is for backward compatibility with existing OpenStack and EC2 API calls. If you decide to create your own call for creating instances not based on `Flavors` or `InstanceTypes` you can ignore this method. The real work is done in `filter_hosts` which must return a list of host tuples for each appropriate host. The set of all available hosts is in the `ZoneManager` object passed into the call as well as the filter query. The host tuple contains (`<hostname>`, `<additional data>`) where `<additional data>` is whatever you want it to be. Cost Scheduler Weighing --------------- +----------------------- Every `ZoneAwareScheduler` derivation must also override the `weigh_hosts` method. This takes the list of filtered hosts (generated by the `filter_hosts` method) and returns a list of weight dicts. The weight dicts must contain two keys: `weight` and `hostname` where `weight` is simply an integer (lower is better) and `hostname` is the name of the host. The list does not need to be sorted, this will be done by the `ZoneAwareScheduler` base class when all the results have been assembled.
