We have developed a specific load balancer , more accurate and a lot more flexible.
It has been specially designed to handle the shared hosting architecture.
Lab tests allowed us to improve the caches:
We have got up to 6x less disk queries.
We will deploy it tonight in order to confirm its performance in a real environment.
Remaining a few settings to make it optimal.
The load balancer is dedicated to work performed on okillerd (which reports any issue on your php scripts, on manager)
Update(s):
Date: 2013-04-12 10:26:04 UTC Balancers are validated on these clusters.
We will soon deploy them on other closed ones.
Date: 2013-04-10 09:54:50 UTC The balancer is activated on cluster 15.
Date: 2013-04-10 02:31:00 UTC Thereafter diagnosis done on cluster 15, we have improved the repartition algorithm.
It has been deployed tonight on cluster 14.
We will reactivate the new predictor on cluster 15 on Wednesday morning.
Date: 2013-04-09 14:55:33 UTC The predictor is temporarily disabled on cluster 15.
Some sites use too many resources, we will have to isolate them on a dedicated one.
Date: 2013-04-09 14:54:37 UTC We have activated the predictor on the cluster 15 (mailplan)
Date: 2013-04-09 01:18:59 UTC The predictor will be activated on Tuesday during the morning.
Date: 2013-04-08 22:51:54 UTC We are preparing the cluster015 (aka mailplan)
Date: 2013-04-05 23:27:15 UTC We have enabled the predictors on cluster014 (the old start)
Date: 2013-04-05 16:19:36 UTC We will test the preduictor on start offer tonight.
Date: 2013-04-02 13:34:29 UTC The distributor is working again and under monitoring's admins.
Date: 2013-03-30 00:04:38 UTC We have reset the old load balancer for this weekend.
Date: 2013-03-30 00:03:53 UTC Load balancer is enabled.
Date: 2013-03-30 00:03:38 UTC Yesterday, we have validated the crash tests: if the system crashes,
the cluster continues to run and switches to the current repartition.
Thereafter the analysis of previous tests, we have improved
the prediction's algorithm.
We are going to activate the module this afternoon.
Date: 2013-03-28 05:32:00 UTC We will stop it during the analysis.
Date: 2013-03-28 05:31:08 UTC The load balancer works properly.
We have many logs to analyze in detail.
Date: 2013-03-28 05:29:40 UTC The load balancer was enabled.
