Cloud services platforms like AWS, Azure, and GCP are reshaping how organizations deliver value to their customers, making cloud migration an increasingly attractive option for running applications. They need enough hardware to serve their anticipated volume and keep things running smoothly without buying too much or too little.

those resources now belong to cloud providers, such as AWS Lambda, Google Cloud Platform, Microsoft Azure, and others. However, when the time comes for resources to be requested, there can be latency in the time it takes to for that code to start back up. The time it takes between an action and a response is latency.

For Physalia, and for AWS more generally, the guiding principle is minimise the blast radius. NSDI’20.

Let's talk about the elephant in the room; Serverless doesn't really mean that there are no Software or Hardware servers. Whether you choose Azure Functions or AWS Lambda, you cannot easily switch to another. Azure Functions don't have this restriction, but on AWS Lambda, functions are not allowed to run for longer than 5 minutes.

We don’t talk about energy as often as we probably should on this blog, but it’s certainly true that our data centres and various IT systems consume an awful lot of it. The goal is to produce a low-energy hardware classifier for embedded applications doing local processing of sensor data. Introducing race logic.

The CFQ works well for many general use cases but lacks latency guarantees. The deadline excels at latency-sensitive use cases ( like databases ), and noop is closer to no schedule at all. For example, on a 128GB memory host, this can allow up to 38.4GB of dirty pages. Two other schedulers are deadline and noop.

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. This is why most AWS regions have three availability zones. Drift into Failure ].

Here's some output from my zfsdist tool, in bcc/BPF, which measures ZFS latency as a histogram on Linux: # zfsdist. Tracing ZFS operation latency. For example, although it's very minor, the /dev/*random devices were faster on Solaris last time I checked, as Linux was spending more effort on entropy for improving security. (Or,

The epoch of AWS is the launch of Amazon S3 on March 14, 2006, now almost 10 years ago. Given that AWS is a pioneer in building and operating these services world-wide, these lessons have been of crucial importance to our business. This is a given, whether you are using the highest quality hardware or lowest cost components.

To reduce latency, assets should be generated in an offline fashion and not in real time. We can leverage high performance VMs in AWS to generate the assets.

To be robust and scalable, this key/value store needs to be distributed for durability and availability, to protect against network partitions or hardware failures. This architecture affords Amazon ECS high availability, low latency, and high throughput because the data store is never pessimistically locked.
