Introduction. In today’s highly competitive world, software development and automation play a significant role in creating robust software applications for businesses. Additionally, emerging technologies like artificial intelligence and blockchain have given a competitive edge to enterprises. For gaining maximum benefits out of automation testing , testers require hands-on experience in a minimum of one automation programming language.
By Alok Tiagi , Hariharan Ananthakrishnan , Ivan Porto Carrero and Keerti Lakshminarayan Netflix has developed a network observability sidecar called Flow Exporter that uses eBPF tracepoints to capture TCP flows at near real time. At much less than 1% of CPU and memory on the instance, this highly performant sidecar provides flow data at scale for network insight.

The goal of AWS Proton is simple: customers should be able to adopt, customize and evolve best practices and technologies for delivering their modern applications to the cloud, and not worry about how they roll this out – potentially to thousands of developers – across their organization.
Whenever we need to do performance testing, mostly it is the APIs that come to mind. Testing the performance of an application by putting load on APIs or on servers and checking out various metrics or parameters falls under server-side performance testing.

I’m weary of always comparing the web to so-called “native” platforms like Android and iOS. The web is streaming, meaning it has none of the resources locally available when you open an app for the first time. This is such a fundamental difference, that many architectural choices from native platforms don’t easily apply to the web — if at all.
We launched our AWS Space Accelerator to catalyze space innovation and support some of the most innovative startups that are helping shape the future of aerospace. Meet the 10 startups to take part in the first cohort of the AWS Space Accelerator.
If you have a public-facing web application, the odds are you should probably be thinking about load testing. Any tester can (and should) add load testing to their repertoire. Functional tests are often carried out with a single user’s experience of your application in mind, but what happens when hundreds or thousands of users are on your site at the same time?
By Gim Mahasintunan on behalf of Data Platform Engineering. Supporting a rapidly growing base of engineers of varied backgrounds using different data stores can be challenging in any organization. Netflix’s internal teams strive to provide leverage by investing in easy-to-use tooling that streamlines the user experience and incorporates best practices.
Dynatrace news. If you ask most people how to secure a web application, you will immediately hear: “Use a web application firewall.” But there is much more to it than that. In this blog, I’ll first cover the basics, explaining what web application security is and why it’s important. Then I will describe various types of security products that can be used for web application security including some innovations that Dynatrace has recently introduced.
For USENIX LISA2021 I gave a 40 minute deep dive talk on BPF internals for Linux, focusing on observability tracing tools. Since there are already BPF internals references online (listed in this post) I used the opportunity to create some new content, showing how bpftrace instrumentation works from user space down to machine code. I break it down to all the small components involved, where you'll find it's actually quite easy.
Introduction. 2 Factor Authentication is a subset of the multi factor authentication service that we see mainly in FinTech Apps. Some financial technology apps ask the user to enter a password, and MPIN, a TPIN, and finally another OTP based authentication to confirm if he/she really wants to withdraw money from their schemes. While 2 Factor authentication may have some vulnerabilities, using a multi factor authentication system like the above will result in users fleeing your application in pur
Application Performance Index. If, like me, you have some difficulties in making a Pass/Fail call for your performance tests when given the Summary Statistics of the performance test results, then the Apdex metric may come in handy. The Application Performance Index defines a score to report the quality of the user experience across any application.

One of the biggest pains of working with statically generated websites is the incrementally slower builds as your app grows. This is an inevitable problem any stack faces at some point and it can strike from different points depending on what kind of product you are working with.
AWS BugBust is the first global bug-busting challenge for developers to fix bugs in a fun and competitive environment. Using modern tools like CodeGuru, we’re able to transform the way we go about bug bashes, improving developer productivity with ML. Our challenge has the ambitious goal of fixing one million bugs and helping AWS customers save $100 million in technical debt.
Web tables, or "data tables," are a common sight in many web-based applications. These tables are predominantly used for displaying information in a tabular format. Rows and columns are the key identifiers of web tables in Selenium. If you’re using tables in Selenium PHP, you can perform several operations on the table, like fetching data from a specific row-column combination, searching for a particular key string in the table, etc.
