As all AEM Developers know, AEM, and more-so the underlying JCR, has limitations on how many children a single parent can have before we start to see performance issues.  First in the UI, and then more critically in the ability to look-up and manage content nodes themselves.  When designing for a net-new AEM website, this […]

Large scale data breaches and critical security vulnerabilities have companies thinking about security more than ever.  Many developers are familiar with the OWASP top 10 (https://owasp.org/www-project-top-ten/) and there are already many resources on generic mitigation for these vulnerabilities.  Instead in this series, I cover security issues and mitigations specific to AEM.  Today’s topic is Sling […]

AEM has a vast infrastructure, and it requires time to hold expertise on it. Every expert was once a beginner, so you are never too late to start and have fun on AEM. In this blog, we will focus on the developers’ perspective of AEM and how one can start as an AEM developer. We […]

Let’s talk about extract, transform, and load, also known as ETL. If you are an AEM professional, this is something you have previously dealt with. It could be something along the lines of products, user bios, or store locations. The extract and transform parts may differ depending on your source and requirements. The loading part […]

The first thing I learned as an AEM developer was mvn clean install -P autoInstallBundle. The second thing was how to debug a remote Java process. The first allowed me to deploy updates I made to the bundle. The second allowed me to step through and debug the code. This was the normal cadence. Since […]

In the first post of the Exploring the Sling Feature Model series, I discussed the process of converting the Sling CMS app from the Sling Provisioning Model to the Sling Feature Model. So how does this apply to your custom applications? To illustrate, let’s convert my personal site, danklco.com, which is currently managed via Sling […]

In a comment on my previous post Apache Sling JVM Performance, Gil Tene made an insightful comment about the potential possibility of performance impact from speed from the underlying environment or other tests. To accommodate for this possibility, I re-ran the tests inside a loop, randomizing order of the JVM execution for each iteration 25 times. […]

With the recent proliferation of Java Virtual Machine (JVM) implementations, it’s difficult to know which implementation is the best for your use case. While proprietary vendors generally prefer Oracle Java, there are several open source options with different approaches and capabilities.  Given how the implementations vary in some underlying technical specifics, the “correct” JVM implementation […]

In my previous post Exploring the Sling Feature Model, I described the process of migrating from a Sling Provisioning project setup to a Sling Feature Model project.  Now that we have the Sling Provisioning Model project converted, we can move on to the fun stuff and create a Composite NodeStore. We’ll use Docker to build […]

In my previous post about AEM as a Cloud Service, How AEM Scales, I discussed the new Sling Feature Model which is a key part of how Adobe scales their new AEM as a Cloud Service solution using Kubernetes.  The goal of the Feature Model is to create a better way to provision Sling instances […]

Did you miss my webinar with the Detroit Adobe Experience Meetup on Sling RepoInit? Sling RepoInit is a newer technology which enables projects to set up permissions, configurations and content via OSGi configurations in a purpose-built grammar. Check out the presentation deck and recording to see how RepoInit could be useful on your project. Watch […]

Curious about using Sling RepoInit? Want to learn more in depth about how Sling RepoInit can enable your AEM DevOps team to manage the initial repository state in code? I’ll be leading a virtual discussion on Sling RepoInit with the Detroit AEM Meetup on Thursday July 9th from 6:00 – 6:50 PM EST. This talk […]
