IT and big data projects can be complex and are often ambiguous by nature. In the case of big data projects, hypotheses about the information contained within the data are either proved or rejected, with new hypotheses then arising. Similarly, assumptions about project requirements are often built into IT projects and stacked on top of one another in advance. Yet, ...

To answer this you’ll have to decide what roles your Envoy-based infrastructure will play ...

Identify which components you need for your control plane As the spectrum of operating environments varies wildly, so too could the components needed to implement a control plane for Envoy. For example, at one extreme, if you have Envoy files statically generated at build time and shipped to your Envoy, you will need components like: Template engineData store / VCSPer-service ...

Envoy has become a popular networking component as of late. Matt Klein wrote a blog a couple years back talking about Envoy’s dynamic configuration API and how it has been part of the reason the adoption curve for Envoy has been up and to the right. He called the blog the “universal data plane API”. With so many other projects ...

Designing an application typically involves focussing on the application requirements from various angles and thus arriving at different design objects and functions and the triggers when these functions are executed. Once done, these are translated into a coherent “functional design” which then gets translated into a “technical design”. A functional design stays at the level of business objects, business functions ...
