In case you don't remember, or missed my first article: OnlineOrNot started as a SaaS I built and shipped a v0.0.1 of in 7 days. It was an Absolute Minimal Viable Product. You couldn't even login with a password. Still can't, actually. You're probably wondering what it does. OnlineOrNot is a website monitoring service that provides both uptime, and page speed checks.
Are you one of those trying to desperately get your hands on a new RTX 3080, 3070, 3060 Ti, & 3090 in 2021? Or maybe you prefer the new PlayStation 5 or Xbox Series X console. Basically, any item that’s on pre-sale or hard to get (including the uniquely designed piece of clothing for your girlfriend).

Kubernetes capacity planning is one of the main challenges that infrastructure engineers have to face, as understanding Kubernetes limits and requests is not an easy thing. You might be reserving way more resources than you need to ensure your containers don’t run out of memory, or are CPU throttled. If you are in this situation, you’re going to be charged for those resources even if they aren’t being used, and it will also make deployments more difficult to schedule.
Grafana Explore makes correlating metrics and logs easy. Prometheus queries are automatically transformed into Loki queries . And we will be extending this feature in Grafana 8.0 to support smooth logs correlation not only from Prometheus, but also from Graphite metrics.

However, Graphite syntax for queries is different, and in order to map it to Loki, some extra setup is required.
Like mechanics who restore their own cars or plastic surgeons who self-rhinoplasty, our developers put their skills to interesting uses during their free time. Here, Native Platform Engineer, Arpad Borsos breaks down how memory mappings and dynamic library loading works and how it relates to native Android libraries loaded from APKs. Libraries are key to modular programming, as they offer functionality in a single unit which can be shared with other developers.
Service Level Objectives (SLOs) are a key component of any successful Site Reliability Engineering initiative. The question is, what are SLOs; and how do you determine what your SLOs should be? Once you've done that, how should you use them?
In software development, processing and storing data in different states reflects the business rules an application is built on.
