If you've been using Let's Encrypt for a while, you may have noticed that their certificates are signed by a root certificate titled DST Root CA X3. That root certificate is set to expire in a few hours. Any certificates still signed by that root will no longer be valid. But luckily, that shouldn't form a problem for most Let's Encrypt users. For a while now, new SSL issuances by Let's Encrypt have issued certificates against DST Root CA X3 (the one that is about to expire) and ISRG Root X1.

Modern software development is evolving rapidly, and while the latest innovations allow companies to grow through greater efficiency, there is a cost. Modern architectures are incredibly complex, which can make it challenging to diagnose and rectify performance issues. Once these issues affect customer experience, the consequences can be costly. So, what is the solution? Observability — which provides a visible overview of the big picture.

The Forge team at Puppet has been hard at work for the past few months building out a malware scanning framework in order to help folks be more proactive about their security posture. Now, to be clear, this doesn't replace your own security mitigations. You should still audit untrusted code. You should still run your own virus protections. There are many layers in a robust security profile, and this is only one of them.

Modern computing has come a long way in the last couple of years and the introduction of new technologies is only accelerating the rate of advancements. From the immense compute power at our disposal to lightning-fast networks and ready-made services, the opportunities are limitless. In such a fast-paced world, we can’t ignore economics.

Distributed systems are everywhere. Although many teams don’t think of their applications as distributed systems, if they’re developing using container-based microservices and serverless functions instead of a monolith, they’re creating a distributed system. This change also means that monitoring needs are becoming more complex.

Storage is one of the most critical components for any relational database management system, and getting the right storage configuration affects reliability, availability, and performance. When it comes to SQL Server storage best practices, choosing between storage hardware options has changed significantly over the last decade, but that doesn’t necessarily make choosing the correct storage options for SQL Server any easier.

We’ve known for some time that the demand for new graphics cards is far exceeding the supply. A combination of the pandemic, natural disasters and unprecedented consumer demand has led to a global chip shortage. The major names in the industry confirm that the supply problem may last in to 2023. At a time when many companies are having to shift more processing to the cloud to support remote workers – this supply problem could not have come at a worse time.

Web servers are software services that store resources for a website and then makes them available over the World Wide Web. These stored resources can be text, images, video and application data. Computers that are interfaced with the server mostly web browsers (clients), request these resources and presents to the user. This basic interaction determines every connection between your computer and the websites you visit.

AWS just announced support for AWS Lambda functions powered by AWS Graviton2 processors. These are 64-bit Arm-based processors that are custom built by AWS and offer a better price to performance ratio. In this post, let me take through what we have learnt about this new option and what it means for you.

Digital operations management is about harnessing the power of data to act when it matters the most. It’s also about having the right processes and procedures to support teams when every second is critical. Maturing your digital operations takes time, iteration, and commitment. The change won’t happen overnight. But, if you put in the effort, you’ll reap outsized benefits. You’ll be able to learn from incidents and proactively improve your services over time.
