Denis Magda commented on IGNITE-790:
------------------------------------
Managed to improve running time complexity of getRegisteredAddresses() from
O(n) to O(1) where "n" is a number of VMs allocated in a cloud. Used badly
documented jcloud functionality.
Additional performance speedup by leveraging not well documented jcloud API
that filters out regions and zones that are out of interest.
Achieved total performance speedup of getRegisteredAdresseses(): AWS (from 50
secs to 3 secs), GCE (from 12 secs to 4 secs), Rackspace (from 42 secs to 8
secs)
> Cross-cloud IpFinder for nodes auto discovering

> Key: IGNITE-790
> URL: https://issues.apache.org/jira/browse/IGNITE-790
> Project: Ignite
> Issue Type: Improvement
> Components: general
> Reporter: Denis Magda
> Assignee: Denis Magda
> Fix For: sprint-5
>
>
> The goal is to create an IpFinder that can be used with many cloud providers
> without a necessity to create a vendor specific implementation.
> The IpFinder must discover Ignite nodes automatically.
> At least at the first iteration the workflow is the following:
> - the finder gets private and public (?) IP addresses (without port numbers)
> of all cloud machines using corresponding jcloud API;
> - optionally the addresses may be filtered out by some predicate (elaborate
> lately);
> - the addresses returned in getRegisteredAddresses() as is, the underlying
> code will add a valid port number;
> User is responsible for:
> - setting all required cloud specific parameters (credentials, secret key);
> - setting a port number that will be used by every Ignite node on every
> machine.
>
> Limitations:
> - only one Ignite node will run per a cloud virtual machine.
> When done, existed S3 and Google Cloud Storage implementations should be
> deprecated.
