Top AWS Metrics to Monitor
The internet plays such a big part in our lives, but most people don’t think about the infrastructure supporting it—except, of course, when it fails. Now, taking a business owner’s point of view, you can own all the software and hardware you need to provide your service, but it also includes regular maintenance. For example, in software, you need to add security fixes, patches, updates, make backups, and so on. As for hardware, you must consider electricity, network cabling, internet provider, securing your building, hardware failures, and more. So, to leverage part of the maintenance tasks for running your application, you use a cloud provider, which will handle all the maintenance activities, leaving you to focus on your business. One of the most used is Amazon Web Services (AWS). Find out all about AWS from Juan Pablo Macias Gonzalez on Solarwinds Appoptic’s site.
Guide to Debugging Ruby on Rails Applications
There are many methods to help you avoid bugs in your application. You can use linters, write tests, or use an IDE, which will help you spot bugs early in the coding phase. However, no matter how good you are at preventing bugs, they will always happen. And it may not have anything to do with you. You could get hit by a bug in the third-party library you use. Therefore, as important as bug prevention is, it’s also crucial to know the debugging process well. Here, you’ll learn how to debug Ruby on Rails applications. Check it out in this post from Dawid Ziolkowski on Solarwinds Papertrail’s blog.
Using Flow Metrics to Measure Value Streams
IT administrators are under enormous pressure to bring software to market in a fast and cost-effective manner. To meet these objectives, IT departments often collect a variety of metrics that measure specific development processes. While data and metrics are definitely helpful, administrators often fail to visualize projects on a macro level and measure total production workflows. This lets bottlenecks and inefficiencies go unnoticed across the value stream, constraining production and negatively impacting business outcomes. Simply put, achieving lean project management and optimal DevOps workflows requires end-to-end visibility across the entire value chain. And the easiest way to do that is by analyzing flow metrics.

A Product Manager’s Guide to Reading Cumulative Flow
The role of a product manager can be overly taxing if core responsibilities are left to chance. This is exactly the reason that a cumulative flow diagram exists. It’s the one chart from which all crucial metrics can be deduced. When explained, a cumulative flow diagram can help you manage the C-suite’s perceptions. Then again, you have to be able to read cumulative flow diagrams for them to spark sense. This post will guide you toward being able to look at a cumulative flow diagram and make useful deductions.

We are all familiar with the way organizations are typically structured along functional lines, such as sales, marketing, development, etc. However, this architecture can lead to a frustrating distance between areas that have to work together to complete a program, project, or even a task. This is especially crucial to consider with security efforts. Whether separated by functional lines, product areas, physical distance, or any other kind of barrier, it’s important to know how to get these groups on the same page. At the Elevate 2021 conference, VP of Nomura Aruneesh Salhotra explained silo issues and how to improve security. Learn more about it on Sonatype’s blog, written by Phil Vuollet.
Real-Time Processing: Difference & (Dis)Advantage Over Batches
Every organization has a mine of data. And when organizations realize that they’re sitting on tons of valuable data, they want to put it to use. But data in its raw form isn’t useful. You have to collect and process data before you can do something useful with it. Data processing is the method of collecting data and converting it into its useful form. You can then use the processed data for analysis, analytics, intelligence, etc. Find out more about data processing from Omkar Hiremath on Scalyr’s blog.
