FIFA World Cup 2022 was a massive spectacle in viewership and marketing revenue. Unfortunately, such an enormous scale of events caused much chaos for some of the apps streaming this global event. This article analyzes those apps from a performance engineering point of view, highlights the reasons for their crash or lags, and tries to provide possible solutions.

Moving to the cloud is one thing, and saving costs is another. One of the reasons why organizations migrate to the cloud is to reduce infrastructure costs. However, caveats like overprovisioning, wasted resources and management issues lead to higher cloud costs. So, here are some best practices to reduce cloud costs and save more on your bills!

In a Kubernetes context, multi-tenancy refers to sharing one large cluster among multiple teams, applications, or users primarily in lower environments such as development and testing—mainly to reduce cost and operational overhead around managing many clusters. Multi-tenancy is becoming an essential requirement for platform teams deploying Kubernetes infrastructure.

Kubernetes adoption survey executive summary. Modern, cloud-native computing is impossible to separate from containers and Kubernetes adoption. While Kubernetes is still a relatively young technology, a large majority of global enterprises use it to run business-critical applications in production. The rapid adoption is driven—and challenged by—an ever-growing ecosystem of Kubernetes technologies that add advanced platform features, such as security, microservice communications, observability, s

Scalable Annotation Service — Marken by Varun Sekhri , Meenakshi Jindal Introduction At Netflix, we have hundreds of micro services each with its own data models or entities. For example, we have a service that stores a movie entity’s metadata or a service that stores metadata about images. All of these services at a later point want to annotate their objects or entities.

I tend to launch most programs on my Windows 10 laptop by typing the <Win> key, then a few letters of the program name, and then hitting enter. On my powerful laptop (SSD and 32 GB of RAM) this process usually takes as long as it takes me to type these characters, just a fraction of a second. Usually. Sometimes, however, it takes longer. A lot longer.

The concept of distributed applications is certainly not new. Whoever has a long IT career certainly remembers a number of different technologies implementing distributed components even in the early years. Nowadays, is all about microservices. They are a new form by which we consider today the concept of distributed computing. Their peculiarity is that their communications are based essentially on REST and messaging protocols, which have the advantage of being widely spread standards.

Plot showing the final result of fitting multiple normal distributions to a response time curve Most people have figured out that the average response time for a web service is a very poor estimate of it’s behavior, as responses are usually much faster than the average, but there’s a long tail of much slower responses. The common way to deal with this is to measure percentiles, and track the 90%, 99% response times for example.

If you’re a Go developer and you’re looking to go serverless, AWS Lambda is a solid choice that will get you up and running in no time. But what happens when you need to connect to your database? With serverless functions, also known as functions as a service (FaaS), you can never be sure about the uptime of your function or how it has chosen to scale automatically with demand.

A couple of days ago I was creating an index on the source and when I checked the replica side it was not replicated, so I just wanted to explain how the replication filter may increase the complexity of your DBA operations. Replication occurs by reading events from the binary log of the source and then executing them on the replica. The events in the binary log are recorded in different formats, depending on the type of event.

If you need test data for the database of your project, you can get a dataset from Kaggle or use a data generator. In the first case, if you need to process the data before inserting it into the database, you can use Pandas, a widely used Python library for data analysis. This library supports different formats, including CSV and JSON, and it also provides a method for inserting data into a SQL database.

Code coverage is a software quality metric commonly used during the development process that let’s you determine the degree of code that has been tested (or executed). To achieve optimal code coverage, it is essential that the test implementation (or test suites) tests a majority percent of the implemented code. There are a number of code coverage tools for languages like Java, C#, JavaScript, etc.

A maximal length sequence of branch-free code that terminates with a branch or jump is referred to as a basic block. A basic block that branches to another forms an edge in the Control Flow Graph (CFG). The initial basic block starting an edge is the predecessor; it precedes and is succeeded by the successor basic block. An edge between basic blocks is considered a critical edge if the predecessor has multiple successors, and the successor has multiple predecessors.
