Based on the activity in bcc, and their development of the BTF and CO-RE technologies, I'd strongly suspect their solution is based on the bcc libbpf-tool versions. ## Porting Pitfalls BPF tracing tools are like application and kernel patches.

There are different considerations when deciding where to allocate resources with latency and cost being the two obvious ones, but compliance sometimes plays an important role as well. The move to the cloud is projected by 2015 see a reduction of 30% in IT infrastructure costs, which amounts to $7.2 blog comments powered by Disqus.

Observability gives developers and system operators real-time awareness of a highly distributed system’s current state based on the data it generates. Metrics are measures of critical system values, such as CPU utilization or average write latency to persistent storage. What is observability?

In 2010, however, nearly none of it existed: the CNCF wasn’t formed until 2015! We had already developed a service mesh control plane that implements the Envoy XDS services. There is a downside to fetching this data on-demand: this adds latency to the first request to a cluster.

This enables customers to serve content to their end users with low latency, giving them the best application experience. In 2011, AWS opened a Point of Presence (PoP) in Stockholm to enable customers to serve content to their end users with low latency. In 2014 and 2015 respectively, AWS opened offices in Stockholm and Espoo, Finland.

The new AWS Africa (Cape Town) Region will have three Availability Zones and provide lower latency to end users across Sub-Saharan Africa. In December of that year, we opened the Amazon Development Center in Cape Town. In 2015, we expanded our presence in the country, opening an AWS office in Johannesburg.

I previously wrote about Netflix in [2015] and [2016], and if you are interested in what it's like to work here, I already covered much in those posts. The proactive projects usually take weeks or months, and are where I'm developing a new technology or helping other teams with performance analysis or evaluations. Time flies!

This motivated the development of DBLog , which offers log and dump processing under a generic framework. 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.

Devices and networks have evolved too: Alex Russell @slightlylate An update on mobile CPUs and the Performance Inequality Gap: Mid-tier Android devices (~$300) now get the single-core performance of a 2014 iPhone and the multi-core perf of a 2015 iPhone. The cheapest (high volume) Androids perform like 2012/2013 iPhones, respectively.

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”. This explains the challenges involved in deploying and testing HTTP/3 yourself.
