By Soheil Esmaeilzadeh , Negin Salajegheh , Amir Ziai , Jeff Boote Introduction Streaming services serve content to millions of users all over the world. These services allow users to stream or download content across a broad category of devices including mobile phones, laptops, and televisions. However, some restrictions are in place, such as the number of active devices, the number of streams, and the number of downloaded titles.
The containerization craze has continued for enterprises, with benefits such as portability, efficiency, and scalability. In fact, according to a Gartner forecast , revenue for global container management software and services will reach $944 million in 2024 — up from $465.8 million in 2020. With the significant growth of container management software and services, enterprises need to find ways to simplify the process.
Suppose we need to sort the collection by multiple keys. In C#, we can do this with the help of OrderBy().OrderBy() or OrderBy().ThenBy(). But what is the difference between these calls? To answer this question, we need to delve into the source code.
Today, I am publishing the Distributed Computing Manifesto, a canonical document from the early days of Amazon that transformed the architecture of Amazon's ecommerce platform. It highlights the challenges we were facing at the end of the 20th century, and hints at where we were headed.

By Vadim Filanovsky and Harshad Sane In one of our previous blogposts, A Microscope on Microservices we outlined three broad domains of observability (or “levels of magnification,” as we referred to them)?—?Fleet-wide, Microservice and Instance. We described the tools and techniques we use to gain insight within each domain. There is, however, a class of problems that requires an even stronger level of magnification going deeper down the stack to introspect CPU microarchitecture.
DevOps and ITOps teams rely on incident management metrics such as mean time to repair (MTTR). These metrics help to keep a network system up and running?, a critical task that’s easier said than done. Other such metrics include uptime, downtime, number of incidents, time between incidents, and time to respond to and resolve an issue. A 2022 Outage Analysis report found that enterprises are struggling to achieve a measurable reduction in outage rates and severity.

Distributed tracing, as the name suggests, is a method of tracking requests as it flows through distributed applications. Along with logs and metrics, distributed tracing makes up the three pillars of observability. While all three signals are important to determine the health of the overall system, distributed tracing has seen significant growth and adoption in recent years.
The optimization of performance testing can contribute to achieving sustainable software engineering. Why is the digital carbon footprint getting bigger every day? What are the best practices to reduce it? Find out everything in this article, with an interview with Mercedes Quintero, Federico Toledo, and. The post Sustainable Software Engineering Through Performance Testing appeared first on Abstracta Software Testing Services.
User experience is the number one priority for every business in the market today. As a developer, even the brief you get on your project talks about the simplicity of the user interface it is supposed to feature.

In the past few years, the complexity of systems architectures drastically increased, especially in distributed, microservices-based architectures. It is extremely hard and, in most cases, inefficient to debug and watch logs, particularly when we have hundreds or even thousands of microservices or modules.
Observability allows visibility into distributed systems for automated problem identification and resolution. Observability-driven development (ODD) is an approach to shift left observability to the earliest stage of the software development life cycle. This article provides a guide on ODD and its benefits, its role in SDLC, and key considerations for adoption.
By: Peter Cioni (Netflix), Alex Schworer (Netflix), Mac Moore (Conductor Tech.), Rachel Kelley (AWS), Ranjit Raju (AWS) Rendering is core to the the VFX process VFX studios around the world create amazing imagery for Netflix productions. Nearly every show that is produced today includes digital visual effects, from the creatures in Stranger Things , to recreating historic London in Bridgerton.
More organizations are adopting a hybrid IT environment, with data center and virtualized components. However, today’s IT teams are stretched thin, with little time to firefight issues with deployment, integration, and data center management. Therefore, they need an environment that offers scalable computing, storage, and networking. That’s where hyperconverged infrastructure, or HCI, comes in.

However, historically, a great deal of testing has been guesswork. We create user journeys, estimate load and think time, run tests, and compare the current result with the baseline.
A few minutes ago, the ISO C++ committee completed its second-to-last meeting of C++23 in Kona, HI, USA. Our host, the Standard C++ Foundation, arranged for high-quality facilities for our six-day meeting from Monday through Saturday. We currently have 26 active subgroups, nine of which met in six parallel tracks throughout the week; some groups ran all week, and others ran for a few days or a part of a day, depending on their workloads.

Agile testing methodology is an integral part of the agile software development process. It is because agile testers allow product owners and stakeholders to communicate.
So you’re building serverless applications with Microsoft Azure Functions, but you need to persist data to a database. What do you do about controlling the number of concurrent connections to your database from the function? What happens if the function currently connected to your database shuts down or a new instance comes online to scale with demand?
by Tomasz Bak and Fabio Kung Introduction Titus is the Netflix cloud container runtime that runs and manages containers at scale. In the time since it was first presented as an advanced Mesos framework, Titus has transparently evolved from being built on top of Mesos to Kubernetes, handling an ever-increasing volume of containers. As the number of Titus users increased over the years, the load and pressure on the system increased substantially.
