Another generic error message from our favorite FaaS provider AWS Lambda. And again, there are multiple reasons why this issue could arise. Let’s first look at the basics of AWS Lambda to get a better intuition for when things go wrong later. Lambda is an asynchronous event-based service at heart.

We’ve been monitoring 100,000’s of serverless backend components for 3+ years at Dashbird. In our experience, Serverless infrastructure failures boil down to: These isolated faults become causes of failure due to dependencies in our cloud architectures (ref. Difference of Fault vs. Failure). If a serverless Lambda function relies on a database that is under stress, the entire API may start returning 5XX errors.

Sometimes, the data you want to analyze lives in AWS S3 buckets by default. If that’s the case for the data you need to work with, good on you: You can easily ingest it into an analytics tool that integrates with S3. But what if you have a data source — such as logs generated by applications running in a Kubernetes cluster — that isn’t stored natively in S3? Can you manage and analyze that data in a cost-efficient, scalable way? The answer is yes, you can.

So you’re using InfluxDB Cloud and you’re taking full advantage of Flux to create custom data processing tasks, checks, and notifications. However, you notice that some of your Flux scripts aren’t executing as quickly as you expect. In this post, we’ll learn about best practices and tools for optimizing Flux performance.

Selecting a web hosting service is essential for making your site go live. But if you are starting up or have a limited budget, it is usually challenging to buy a hosting service costing as much as $100 per year. Most of the paid plans don't offer a free trial. If you just want to try a blogging idea, practice designing a website, or have limited to no earnings, you can get started with free web hosting.

Avid kite flyer, publisher, and postmaster Benjamin Franklin is believed to have coined the catchphrase, “time is money”. If only he had known just how relevant the phrase would become hundreds of years later, especially when it comes to the relationship between customer expectations of your website’s page load times and lost revenue. Page load time is the time it takes your browser to retrieve a page, with all content, and display it in full.

I have been working on a couple of monitoring ideas for Cherwell. I didn’t see anything with a quick online search, and I enjoy authoring MPs to monitor applications, it is the closest I’ll get to 007. I’ve hit a major hurdle and I need to ask for a hand from the community. We have a lab environment that’s worked great while developing the Cherwell integration for Connection Center, however, it is not a good simulation for an actual deployment.

In space, there’s no atmosphere to protect against the sun’s ultraviolet radiation. Astronauts in orbit are exposed to the equivalent of eight X-rays a day, and the space stations and suits that protect them degrade over time due to radiation and other factors. Scientists working on the International Space Station (ISS) want to know more about ultraviolet (UV) radiation in orbit so they can design better materials.
