Encryption at rest with Ceph

Do you have a big data center? Do you have terabytes of confidential data stored in that data center? Are you worried that your data might be exposed to malicious attacks? One of the most prominent security features of storage solutions is encryption at rest. This blog will explain this in more detail and how it is implemented in Charmed Ceph, Canonical’s software-defined storage solution.

Data science workflows on Kubernetes with Kubeflow pipelines: Part 2

This blog series is part of the joint collaboration between Canonical and Manceps. Visit our AI consulting and delivery services page to know more. Kubeflow Pipelines are a great way to build portable, scalable machine learning workflows. It is a part of the Kubeflow project that aims to reduce the complexity and time involved with training and deploying machine learning models at scale. For more on Kubeflow, read our Kubernetes for data science: meet Kubeflow post.

Importance of System Resource Monitoring on Graylog, Elasticsearch, and MongoDB Servers

The first thing we tell Graylog users is, “Monitor your disk space.” The core set of metrics discussed below should always be in acceptable parameters and never grow over extended periods without going back to normal levels. This is why it is critical to monitor metrics that come directly from the hosts running your Graylog infrastructure.

Guide to Serverless Information Security

Information security (infosec) is a broad field. Its practitioners behave more like artists than engineers. After all, the mandate for security is not “do X”, but instead “ensure no one can do X, Y, Z, ɑ, β, ɣ, etc.”. The array of possibilities leading to infosec failure are vast. It’s like trying to prove a negative, thus making the task near impossible. On one hand we have an impossible task, on the other we have the affordance of time.

Achieving a 12% performance lift migrating Raygun's API to .NET Core 3.1

Here at Raygun, improving performance is baked into our culture. We don't just think about our application performance, but more broadly, we look at our own infrastructure and ask if there's anything we can do to make it more performant for our business and for our customers. Two years ago, we switched our API from Node.js to .NET Core and achieved a 2000% increase in throughput. To continue that story, we recently upgraded .NET Core 2.1 to 3.1 and saw a 12% increase in performance. We enjoy presenting our performance findings, so in this post, we'd like to give some context into why we upgraded and the conditions that helped us achieve the 12% performance lift.

How To Monitor Zoom Audio Video Conference Performance

With governments and businesses requiring workers to stay and work from home during this unprecedented global pandemic, enterprises are now more dependent than ever before on real time collaboration tools like Microsoft Teams, Zoom, and Cisco WebEx. IT staff within these organizations are under pressure to provide their Sr. Management a level of assurance that these tools are working well in this scenario. But with workers running devices IT doesn't own over networks they don't control means IT needs innovate quickly and find tools that can help them and help them fast.

Docker monitoring made easy

Docker is a platform that enables developers to run software in packaged environments called containers. These containers are operating system (OS)-level virtualized elements that share a common Linux server yet have their software, libraries, and configuration files bundled within them. These containers can communicate with each other and exchange information, making it easier to develop and host multiple applications through the CI/CD DevOps methodology.

Maintaining stellar website performance

When was the last time you checked your website’s performance? If your answer is longer than five minutes ago, you’re dropping the ball on one of the most important things you can do to improve bounce rates, Google rankings, conversions, and revenue. In this article, we go over the steps you need to take when maintaining a fast user experience.

SLO Adoption at Twitter

This is the second article of a two-part series. Click here for part 1 of the interview with Brian, Carrie, JP, and Zac to learn more about Twitter’s SRE journey. Previously, we saw how SRE at Twitter has transformed their engineering practice to drive production readiness at scale. The concept of service level objectives (SLOs) and error budgets have been key to this transformation, as SLOs shape an organization’s ability to make data-oriented decisions around reliability.
