Azure Spring Apps is a fully managed service from Microsoft (built in collaboration with VMware), focused on building and deploying Spring Boot applications on Azure Cloud without worrying about Kubernetes.

And, the Enterprise plan comes with some interesting features, such as commercial Spring runtime support, a 99.95% SLA and some deep discounts (up to 47%) when you are ready for production.

>> Learn more and deploy your first Spring Boot app to Azure.

You can also ask questions and leave feedback on the Azure Spring Apps GitHub page.

Slow MySQL query performance is all too common. Of course it is. A good way to go is, naturally, a dedicated profiler that actually understands the ins and outs of MySQL.

The Jet Profiler was built for MySQL only, so it can do things like real-time query performance, focus on most used tables or most frequent queries, quickly identify performance issues and basically help you optimize your queries.

Critically, it has very minimal impact on your server's performance, with most of the profiling work done separately - so it needs no server changes, agents or separate services.

Basically, you install the desktop application, connect to your MySQL server, hit the record button, and you'll have results within minutes:

Looking for the ideal Linux distro for running modern Spring apps in the cloud?

Meet Alpaquita Linux: lightweight, secure, and powerful enough to handle heavy workloads.

This distro is specifically designed for running Java apps. It builds upon Alpine and features significant enhancements to excel in high-density container environments while meeting enterprise-grade security standards.

Specifically, the container image size is ~30% smaller than standard options, and it consumes up to 30% less RAM:

Yes, Spring Security can be complex, from the more advanced functionality within the Core to the deep OAuth support in the framework.

I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

You can explore the course here:

DbSchema is a super-flexible database designer, which can take you from designing the DB with your team all the way to safely deploying the schema.

The way it does all of that is by using a design model, a database-independent image of the schema, which can be shared in a team using GIT and compared or deployed on to any database.

And, of course, it can be heavily visual, allowing you to interact with the database using diagrams, visually compose queries, explore the data, generate random data, import data or build HTML5 database reports.

Creating PDFs is actually surprisingly hard. When we first tried, none of the existing PDF libraries met our needs. So we made DocRaptor for ourselves and later launched it as one of the first HTML-to-PDF APIs.

We think DocRaptor is the fastest and most scalable way to make PDFs, especially high-quality or complex PDFs. And as developers ourselves, we love good documentation, no-account trial keys, and an easy setup process.
