NewRelic Logs With Logback on Azure Cloud

Aggregated on: 2023-05-04 18:45:26

Those who work with NewRelic logs for Java applications probably know that the user of an agent might be the most flexible and convenient way to collect log data and gather different application metrics, like CPU and memory usage and execution time. However, to run a Java application with the agent, we need access to an application execution unit (like a jar or Docker image) and control an execution runtime (e.g., an image with JVM on Kubernetes). Having such access, we can set up Java command line arguments, including necessary configurations for the agent. Though, Azure Cloud-managed services, such as Azure Data Factory (ADF) or Logic Apps, do not have "tangible" executed artifacts nor execution environments. Such services are fully managed, and their execution runtimes are virtual. For these services, Azure suggests using Insights and Monitor to collect logs, metrics, and events to create alerts. But if your company has a separate solution for centralized log collection, like NewRelic, it could be a challenge to integrate managed services with an external logging framework.

Zipping up the Lambda Architecture for Faster Performance

Aggregated on: 2023-05-03 20:30:26

The Lambda architecture has been common practice in big data processing. The concept is to separate stream (real-time data), and batch (offline data) processing, and that's exactly what we did. These two types of data of ours were processed in two isolated tubes before they were pooled together and ready for searches and queries. Then we run into a few problems:

Privacy Risk of ChatGPT for Software Developers

Aggregated on: 2023-05-03 20:30:26

ChatGPT is a relatively new technology that is set to revolutionize how software developers interact with AI. With its ability to generate code autonomously from text, ChatGPT could drastically reduce development time and complexity while allowing developers an unprecedented level of control over their projects. However, despite the advantages it provides all users, one question persists: what privacy risks does chatGPT introduce for software developers? According to ExpressVPN, no matter what type of tool or solution you use for software development projects, data privacy is significantly important to protect your data from marketing companies and malicious persons.

What Are Events? Always 'Decoupled'

Aggregated on: 2023-05-03 18:45:26

In January 2021, I wrote that Event Driven Architecture (EDA) should be "Always Asynchronous." At precisely the same time, I argued that "the concept that we are actually trying to explain when we use the term 'Asynchronous' — within the context of EDA — might be better termed: 'Monologueous Communication'" (where no response is ever required). Nonetheless, 'Asynchronous' remains the dominant term in use today, and it was never certain that 'Monologueous Communication' was a good replacement. As the months have passed, however, I see more and more clearly how using the term 'Asynchronous' represents a major obstacle to our shared comprehension of EDA. Let me give you an almost unbelievable example that I witnessed from the CTO of the global computing giant AWS at its recent re: Invent Summit in December 2022. Of course, it goes without saying that the CTO of AWS is as well placed as anyone in the world to explain to an ignorant public was 'Asynchronous' actually means, for which reason I find this example so incredibly useful (please do not take it as a pointless exercise in AWS-bashing).
