This article is the final installment in a series that demystifies observability. The first three focused on the history of observability, dispelling myths around observability, and what observability is and what it can offer. In this last article of the series (Check out part 1), I want to offer a complete definition of observability.
Complex, distributed software systems are chatty things. Because there are many components interoperating amongst themselves and with things outside their bounds like users, those components and the systems themselves emit many information signals. It’s the goal of monitoring, logging, and observability (o11y) tools to help the systems’ “stewards,” those developers and operators tasked with maintaining and supporting them, make sense of those signals.
A couple of weeks ago, TIgera engineers released the new version of Calico, as part of a community effort to drive cloud security and networking even further. But before I begin diving into the details of this new release, I want to first spotlight a few of our community members who have merged their contributions to Calico Open Source for the first time.
We recently broadcast a webinar to discuss DDoS trends and developments. Our partner Cloudflare had their cybersecurity evangelist, Ameet Naik, join us along with our own Doug Madory, head of internet analysis. I had the pleasure of moderating the discussion.
When you maintain an internal or public-facing API, the API documentation is an important component of the overall user/developer experience. One of the industry standards for such documentation is the OpenAPI specification. With an OpenAPI specification, you define a contract that specifies how your API should behave, but nothing stops the parties involved from breaking such a contract (e.g., using a wrong implementation or invalid input).
Wouldn’t it be great if all business transactions could be conducted over lunch and executed with a handshake? It would sure cut down on the paperwork. Unfortunately, business is far too complicated for the kind of vagueness and misunderstanding that would arise from such a deal. Everything needs to be in writing. Love them or hate them, those piles of paperwork are your allies. This is especially true when evolving your business from a break/fix model to managed services.
Armin Müller is the co-founder of ScopeSET. ScopeSET specializes in R&D work to build and integrate tools in the model-based systems engineering domain, with a track record of more than 15 years of delivering innovative solutions for ESA and the aerospace industry. Training machine learning models takes a lot of time, so we’re always looking for ways to accelerate the process at ScopeSET. We use open source components to build research and development tools for technical companies.
A quick search of the internet will reveal many services available for freely hosting single page applications or static sites. Firebase is one of these services. Firebase is a development platform developed by Google that provides file storage, hosting, database, authentication, and analytics. It is free, provides an SSL certificate by default, and offers impressive speed across multiple regions. I have chosen Firebase for hosting our demo application in this tutorial.
