In the early days of log analysis, application developers would use their logging libraries to write logs to files stored on a disk. After years of relying on those libraries, they found that they were unable to monitor the performance of their applications anymore because they didn’t understand the way their logging libraries worked. This led to a shift from using log files stored on a disk to using Syslog.

Database security includes a variety of measures used to secure database management systems from vicious cyber-attacks and illegitimate use. Database security programs are designed to protect not only the data within the database but also the data management system itself, and every application that accesses it, from destruction, mishandling, and unauthorized access.

Even reducing the loading time of our website by a second can have a drastic impact on the traffic we get. It is vital for our websites to load quickly in this fast-moving world, where all the information we need can be found within a blink of an eye. One way to achieve it is using Gzip compression. The Gzip algorithm compresses and decompresses data in order to make websites load faster in a client's machine.

Data Obfuscation is a way of making data unreadable or unusable if data breach occurs. It is like providing security to the data by encrypting it or masking it in order to make it unreadable even when the hackers can do a successful data breach. Data breaching is very common these days and every organization must protect its own data. Even if we cannot stop the data breach completely, we can save the data we have by means of data obfuscation.

Node.js is the most popular tool for developing server applications in JavaScript, the world's most widely used programming language. Node.js is now regarded as a critical tool for all types of microservices-based development and delivery, as it has the capabilities of both a web server and an application server. In any web application, performance is critical. Faster performance in any web application improves the user experience and leads to increased revenue, which makes business owners pleased.

Users nowadays demand the greatest possible experience, which implies top-notch performance. Smooth scrolling, prompt interaction responses, a fast page load time, and flawless animations are all things they anticipate. Local profiling to identify performance issues is convenient, but it only provides a limited amount of information. While things may run smoothly on our high-end developer machines, the user may be dealing with poor hardware and a bad experience.

Apache has been around since 1995 and is the most important web technology. The majority of businesses nowadays run-on Apache servers. Different servers operate in different ways and have different features and functions. For simple debugging, several servers keep server logs. Understanding how the server works is essential. All errors encountered by the server while receiving or processing requests are recorded in the Apache error logs.

Monitoring and analyzing log files to identify and resolve issues make up log observability. Log analytics is the process of extracting insights from log data. Logs are a valuable source of information for IT operations teams, as they provide insight into what is happening on a system or network. Logs can monitor system performance, troubleshoot problems, and identify security incidents. Logs are a vital part of application performance management.

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.
