DLVs are particularly advantageous for databases with large allocated storage, high I/O per second (IOPS) requirements, or latency-sensitive workloads. For write-only traffic, the QPS counters match the performance of standard RDS instances for lower thread counts, though, for higher counters, there is a drastic improvement.

When you’re running in the cloud your containers are in a shared space; in particular they share the CPU’s memory hierarchy of the host instance. These applications range from critical low-latency services powering our customer-facing video streaming service, to batch jobs for encoding or machine learning.

OpenTelemetry , the open source observability tool, has become the go-to standard for instrumenting custom applications to collect observability telemetry data. Monitoring DNS query time is important for understanding network latency, ensuring that services are available, troubleshooting issues, and optimizing application performance.

There are several open source CDC projects, often using the same underlying libraries, database APIs, and protocols. No locks on tables are ever acquired, which prevent impacting write traffic on the source database. Hence, downstream consumers receive change events as they occur on a source.

Netflix shares how Amazon EC2 Auto Scaling allows its infrastructure to automatically adapt to changing traffic patterns in order to keep its audience entertained and its costs on target. Netflix runs dozens of stateful services on AWS under strict sub-millisecond tail-latency requirements, which brings unique challenges. Wednesday?—?December

Most existing adtech infrastructure simply can not achieve the required latency. VoltDB provides the necessary technology to achieve the latency required by header bidding. And while it’s easy to say “spin up more AWS servers”, you’re only adding to your cloud provider bill. Another adtech infrastructure problem is capacity.

Collecting some critical metrics at one second intervals, with a total observability latency of ten seconds or less matches the human attention span much better. For systems that are latency sensitive, creating two independent ways to succeed is an important technique for greatly reducing the 99th percentile latency.

I also rewrote the section on Startup Latency since Cold Starts are one of the big “FUD” areas of Serverless. Also there’s been a lot of open source updates, including from Amazon and Microsoft.
