For the curious: DDE is a pre-templeted Solr-optimized cluster deployment option in CDP, and recently released in tech preview. We will only cover AWS and S3 environments in this blog.

Things are likely picking up where you are, which makes it the perfect time to focus on test execution to put yourself ahead. Quality at the expense of speed, or speed at the expense of quality, is likely a challenge you have faced in your development journey.
Innovation is a topic of conversation in almost every enterprise, but a related topic that sometimes goes under-discussed is co-innovation—that is, the idea that enterprises can unlock a lot of powerful business innovation by partnering outside the organization. Often called a digital ecosystems strategy, this tactic involves different participants sharing data, functionality, and other digital assets for symbiotic benefit.

For many freelancers and small business owners, moving from consulting or freelance development work to operating a SaaS product is the Holy Grail. That makes sense: running a SaaS scales better and makes for a stable income. While there’s no guaranteed path to success, here’s what we learned taking AppSignal from a “20% time side-project” to a business serving thousands of developers around the globe. This article isn’t a blueprint.
