Very recently, the JFrog security research team has disclosed an issue in the H2 database console which was issued a critical CVE – CVE-2021-42392. This issue has the same root cause as the infamous Log4Shell vulnerability in Apache Log4j (JNDI remote class loading). H2 is a very popular open-source Java SQL database offering a lightweight in-memory solution that doesn’t require data to be stored on disk.

DigitalOcean, or DO, brands itself as the “developer cloud,” and it’s no secret that it has a strong mind-share among developers, especially because of factors such as simple UI, performance, structured documentation, a robust community ecosystem, and last but not least, the affordable pricing. As developers started adopting microservices as the architecture of choice for their applications, DO responded quickly and launched their Managed Kubernetes offering, labeled DOKS.

If you’re like most organizations, you’re leveraging Jenkins for all sorts of things. Deployment pipelines, automated API tests, even glorified CRON jobs just to name a few.

Happy New Year 2022! The fireworks are all fired, the champagne is over. It is time to get back to work. We are glad to see you here though. 2021 was a good year for OpenStack and its Ubuntu-based community. First, we all have seen Ubuntu becoming the number one operating system (OS) for OpenStack deployment. Then, the Open Infrastructure Foundation (OIF) reported explosive growth in the number of production OpenStack clouds. The community grew and settled on the most convenient platform.

The previous blog post talked about the composability of applications. The key element for composing applications is defining the relations between application elements. And supporting relations is one of the advantages of the Charmed Operator Framework – including its runtime, the Charmed Operator Lifecycle Manager.

SD-WAN is one of the fastest-growing segments of the network infrastructure market. Designed correctly, it will deliver unique advantages, enabling true digital transformation while reducing costs and management time and increasing application performance, availability, visibility and user experience. While the benefits of SD-WAN are obvious, we know it can often be a challenge to select the appropriate approach to design, implementation, and ongoing management.

The database/sql package in the Go standard library maintains a pool of connections so that all queries going through a single *sql.DB instance will reuse the same pool. This is great because you get a connection pool out of the box. But what if you need to share the same connection pool across processes? How do you use the same API in different processes but still reuse the same pool?

Rancher Desktop has been in development for just over a year with the open question: when do we have a 1.0.0 stable release? Along the way the scope has expanded, it was ported to run in more places and the development team has grown. All of this happened as we worked out if Rancher Desktop would be useful for people, what features people want to use and what are good ways to build it. We are finally ready to answer that 1.0.0 question.

An email recently came to our team (the Redgate Advocates) asking us what we thought the key challenges for data professionals might be in 2022. Kathi Kellenberger, Steve Jones and I each answered independently. We all bring different experiences and thoughts to the table, yet we all came up with three common themes. Here is what we all feel is likely to be of the most importance this year.
