Scaling the Firehose API and Consumers
If you’re still losing logs even though you’ve correctly scaled Dopplers, you probably need to scale your Firehose API and consumers.
Scaling Doppler VMs in Cloud Foundry
When your Cloud Foundry logging system is not working optimally, one of the reasons could be improperly scaled Doppler VMs. Read this learn if this is the case and get general guidelines for how to properly scale your Doppler VMs.
A High-performing Mid-range NAS Server, Part 3: 10 GbE
Upgrading our iSCSI (Internet Small Computer System Interface) NAS
(network-attached storage) server from 1 GbE (gigabit ethernet) to 10 GbE
increased our vSphere VM’s (Virtual Machine’s) sequential read throughput 43%,
sequential write throughput 940% (!), and IOPS (Input/Output Operations Per
Benchmarking the Disk Speed of IaaSes
It’s helpful to know the performance characteristics when selecting a disk
type for an Infrastructure as a Service (IaaS). In this blog post we describe
the results of benchmarking various disk types of various IaaSes, including
Amazon Web Services (AWS), Microsoft Azure, Google Compute Engine (GCE), and
VMware vSphere. We measure Input/output operations per second (IOPS), read
throughput, and write throughput.
