The need for systems to be resilient is still increasing, and chaos engineering tools and techniques are developing as a key way to validate that resilience is working as designed. If you are building resilient systems with failover, the control plane that manages failover is often the hardest part of the system to get right.

My last talk for 2017 was at AWS re:Invent, on "How Netflix Tunes EC2 Instances for Performance," an updated version of my [2014] talk. A video of the talk is on youtube : The slides are on slideshare : I love this talk as I get to share more about what the Performance and Operating Systems team at Netflix does, rather than just my work.

If your app runs in a public cloud, such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP), the provider secures the infrastructure, while you’re responsible for security measures within applications and configurations. What are some key characteristics of securing cloud applications?

Clouds using Ethernet that are multipath optimized using libfabric and features like EFA on AWS are going to be increasingly competitive, and Ethernet will replace other interconnects between racks. I presented a keynote for Sun at Supercomputing 2003 in Phoenix Arizona and included the slide shown below.

Energy data at the entire machine or raw cloud instance level needs to be apportioned to virtual machines or cloud instances which run an operating system, and to pods, containers and processes running applications and background activities that consume CPU, memory and I/O resources.

In all cases this is random data so presents no security challenges. If not are you going to “clean” your data so it does not present a security risk? This is especially important as the number of official published benchmarks has reduced over time as shown in the graph from this presentation on TPC relevance.

Microservices fundamentally change a lot of assumptions current cloud systems are designed with, and present both opportunities and challenges when optimizing for quality of service (QoS) and utilization. In this paper we explore the implications microservices have across the cloud system stack. Tail at scale implications.

For high resiliency systems, it’s even better to use the “rule of three” and quorum based algorithms. This is why most AWS regions have three availability zones. When there’s three ways to succeed, we still have two ways to succeed when a failure is present, and if data is corrupted, we can tell which of the three is the odd one out.

If you are using ChatGPT in any situation where correctness matters, you must be extremely careful to check ChatGPT’s logic and anything it presents as a statement of fact. It does a great job of collecting and presenting data. And some of these things are mind blowing.

Brotli is widely supported, and many CDNs support it ( Akamai , AWS , KeyCDN , Fastly , Cloudlare , CDN77 ) and you can enable Brotli even on CDNs that don’t support it yet (with a service worker). It isn’t supported consistently and has some caching issues (see slide 114 onwards of Hooman Beheshti’s presentation ). Image source ).
