Building distributed systems on the shoulders of giants

Developing a distributed system is one of the hardest things you will do as a software developer. You will end up having to deal with topics like network inconsistencies, load balancing and service discovery etc. Only to find that solving these problems require expert level knowledge. What if I told you there was a way to leverage the expertise of industry leaders like Google/Microsoft and benefit from their research so you don’t have to reinvent the wheel? Let’s investigate some tools you can use today to build modern, resilient and scalable microservices. Technologies like Service Fabric, Knative, Istio and DAPR can give you the right foundation to build on top of so you can concentrate on solving the business domain problems and be productive.

Developing a distributed system requires expert knowledge that not every mortal software developer has. This results in most Microservices failing in production scenarios under load or intermittent network conditions. There is a better way than expecting every developer to do these complex calculations. We can leverage the knowledge from experts by using some modern distributed applications runtimes and tools that give us a good foundation. (Standing on the shoulders of giants) This frees us to focus on the domain and solve it better. In this talk I want to introduce (compare and contrast) developers to some of these choices.
