IP Blacklists contain ranges of or individual IP addresses ‌you want to block. A blacklist can be used in combination with firewalls, intrusion prevention systems (IPS), and other traffic filtering tools. With the recent developments in cyber security, organizations are increasingly relying on IP blacklisting to protect their networks.

Node.js is well-known for its lightning-fast performance. However, as with any programming language, you might develop Node.js code that performs poorly for your users. Appropriate performance testing is required to combat this. Node.js can be used for a variety of tasks, including scripting to do tasks, running a web server, and serving static files, such as a website. Today, we'll go over the procedures to test a Node.js HTTP web API.

RabbitMQ is one of the most popular open-source message brokers available. Its ability to be deployed in various configurations and on various platforms makes it a widely used tool; it also supports all major messaging protocols, making it very versatile. Still, debugging issues with a tool like RabbitMQ can be challenging, especially when it’s deployed on a large cluster. RabbitMQ logs are one way to go, as they help you backtrack to an earlier point while debugging.

IaC (Infrastructure-as-Code) is becoming ubiquitous in the EUC (End User Computing) community and within the datacenter. Automation and declarative infrastructure for on-premises VDI and cloud digital workspaces, such as Microsoft AVD (Azure Virtual Desktop) or AWS WorkSpaces, is now mainstream. Vendors such as Citrix now advocate the use of technologies such as Terraform and Ansible for deployments.

The Internet is a vast network of servers and devices connecting people worldwide. It allows for near-instant data communication between machines, which is presented in a readable format for the end-user. From a human perspective, it's a simple case of typing the URL of your desired website and pressing enter. Of course, computers talk to one another in their own numerical language, using lengthy IP addresses to refer to domains instead of URLs.

Too many of us are still playing whack-a-mole when it comes to incidents: an incident is declared, the on-call engineer is paged, the incident is resolved and then forgotten — until next time. It’s time to start thinking in terms of proactive incident management, not just reactive incident response.

From the point of view of your business, resources and tools that are underutilized are a liability. They can severely affect the bottom line of your enterprise. These tools can cost more than their value, present security risks, and hamper productivity within your enterprise. Even if a particular tool was helpful during the growth of your enterprise, it could soon become obsolete.

Monitoring is often not the first thing on the mind of the modern developer. Yet, it’s necessary at many points of the software development lifecycle, including: before deprecating an API, before launching a new feature, after launching the feature, and more. In fact, monitoring needs can vary much more than the classic Ops monitoring. My podcast guest Liran Haimovitch is the co-founder and CTO of Rookout, a live data collection and debugging platform.
