Amazon Elastic Compute Cloud (a.k.a., EC2), is no doubt the core current computing infrastructure. It sits at the heart of AWS, the main kind of structure for housing virtual machines and containers for development and operations. Applying standards of observability with EC2 logs and obviously EC2 metrics (or any kind of AWS metrics for that matter) will inform you on if you have the right sorts of instances in place (and the appropriate size of those instances).

The Log4J library is one of the most widely-used logging libraries for Java code. On the 24th of November 2021, Alibaba’s Cloud Security Team found a vulnerability in the Log4J, also known as log4shell, framework that provides attackers with a simple way to run arbitrary code on any machine that uses a vulnerable version of the Log4J. This vulnerability was publicly disclosed on the 9th of December 2021.

Life is all about perspective, and the way we look at things often defines us as individuals, professionals, business entities, and products. How you understand the world is influenced by many details, or in the case of your application – many data sources. At Coralogix, we not only preach comprehensive data analysis but strive to enable it by continuously adding new ways to collect data.

If you have been trying to compare all of the best data visualisation tools you may have found it difficult to find a detailed list that includes both open-source and proprietary solutions to help you compare and make an informed decision on what you need going forward. In this guide, you will find out everything you need to know about the leading solutions for data visualisation to help you get started with your next analysis project.

While I write this blog post, I reflect on the years of being a system administrator and the task of ensuring that no sensitive data made its way past me. What a daunting task right? The idea that sensitive data can make its way through our systems and other tools and reports is terrifying! Not to mention the potential financial/contractual problems this can cause.

We are living in a data world. Data describes and controls almost every aspect of our life, from the president's elections to everyday grocery shopping. Data grows exponentially and so does the complexity of applications that manage that data. We all know the recent shift to microservices and other revolutionary changes that happened in the way we design, develop, deploy and operate modern applications.

On December 9, 2021, a vulnerability was reported that could allow a system running Apache Log4j 2 version 2.14.1 or below to be compromised and allow an attacker to execute arbitrary code on the vulnerable server. This vulnerability was registered on the National Vulnerability Database as CVE-2021-44228, with a severity score of 10. Here is a diagram of the attack chain from the Swiss Government Computer Emergency Response Team (GovCERT).

Logfile analysis plays a central role in enhancing the observability of your IT estate, helping operations teams and SRE engineers to identify issues as they emerge and track down the cause of failures quickly. As the number of log entries generated on any given day in a medium-sized business easily numbers in the thousands, viewing and analyzing logs manually to realize these benefits is not a realistic option. This is where automated real-time log analysis comes in.
