Welcome to our monthly recap of the articles we published in June! This month, we rolled out an armada of articles to help you build—and lock down—code on the platforms you trust. Here are the June highlights.
Security for Kubernetes, Go, and beyond
Kubernetes is increasingly central to modern distributed and containerized development today, but it's a complex system that's difficult to secure. Ajmal Kohgadai and Andy Oram delivered a three-part series on Kubernetes security to help put your mind at ease:
- Kubernetes security risks that keep developers up at night
- 4 tips for achieving better security on Kubernetes
- Best practices for successful DevSecOps
Andy also rounded things out with a tour of 8 great open source Kubernetes security tools.
Red Hat Developer also took a look at security issues in the Go language. We provided a primer on cross-site scripting that explained how you can prevent this type of attack when building applications in Go; we also showed you how to make sure your Go applications on RHEL comply with the FIPS standard mandated for U.S. government contractors.
And finally, if you're dealing with good old-fashioned C, Serge Guelton and Siddhesh Poyarekar taught you how to use compiler flags to protect against stack-smashing attacks.
Dig deep into internals
Some of our most popular articles of this month really got into the nitty-gritty of code execution, compilation, and performance monitoring. Thanks to Red Hat Developer's experts, you learned how to:
- Use the GNU Debugger to debug stack frames and recursion, a common cause of programming errors.
- Use the Bunsen test suite to track down "flaky" tests that produce different outcomes when run repeatedly.
- Monitor the performance of BPF programs that themselves inspect other system activity.
- Reveal potential performance problems, down to individual lines of code, with SystemTap and one of its prewritten example scripts.
SaaS architectures
We continued a series that we began in May about building and deploying Software as a service (SaaS) applications, and these also proved to be a big hit with readers. This month, you learned how to:
- Convert an existing web application into a SaaS service.
- Develop a multi-cloud storage strategy to accommodate different environments where your SaaS service might be deployed.
Check out these articles and be on the lookout for future installments.
Instrument containerized Java applications with Cryostat
You probably have used Java Flight Recorder, an excellent tool for analyzing and understanding Java workloads. It comes in handy during development or while workloads run in production. Cryostat takes that further by bringing the same functionality to containers and Kubernetes. You can check out our roundup of what's new in Cryostat 2.1, the latest version of the tool. You can also learn how to install Cryostat using a Helm chart, which is suitable for demo purposes and simpler than using the Cryostat Operator.
