By the summer of 2020, many UI engineers were ready to move to GraphQL. To determine customer impact, we could compare various metrics such as error rates, latencies, and time to render. Watch our Chaos Engineering talk from AWS Reinvent to learn more about Sticky Canaries.

Today, I'm happy to announce that the AWS GovCloud (US-East) Region, our 19th global infrastructure Region, is now available for use by customers in the US. With this launch, AWS now provides 57 Availability Zones, with another 12 zones and four Regions in Bahrain, Cape Town, Hong Kong SAR, and Stockholm expected to come online by 2020.

An average of 434 ms is awful, and a small queue size (aqu-sz) indicates it's a problem with the disk and not the workload applied. From these outputs I try to determine if the problem is: - **The workload**: High-latency disk I/O is commonly caused by the workload applied. Note the sdb latencies range from 32 ms to over 2 seconds!

There are services at Netflix that use RDBMS kind of databases such as MySQL or PostgreSQL via AWS RDS. Passive instances across regions are also possible, though it is recommended to operate in the same region as the database host in order to keep the change capture latencies low. The destination may be a datastore or an external API.

This proximity significantly reduces the time it takes for the data to travel from the server to the user, thus reducing latency and improving load times. Bookaway site search.

For applications like communication between AVs, latency–how long it takes to get a response–is more likely to be a bigger limitation than raw bandwidth, and is subject to limits imposed by physics. There are impressive estimates for latency for 5G, but reality has a tendency to be harsh on such predictions.
