Golang basics for Java developers

I put together a quick introduction to my Java colleagues into Golang to make some appetite to try it out. This presentation is the first in the series of Microservice development with Golang and focusing on the language elements sprinkled with example code links. It tries to compare them with Java to help the easier understanding, why Go has a potential in enterprise environment even in private/hybrid or private cloud scenarios with low resource usage and efficient concurrency.

Microservices: just a trend or real evolution?

Today I had a discussion with my colleague about the necessary coding style changes in microservice development. In my opinion we should revise our practices for simplifications, because we socialized on code reusability in monoliths and these new kids on the block are playing differently. At the end of the discussion he asked a question from me:

“Is the microservice architecture is a trend or evolution?

Microservice benefits

Lot of pages listing why do we need microservices and writing long-long lists about their magical nature, but I think it has two main reasons: scalability and development time. In some blog post the list has more items like:

• resilience (no, just restarts faster...)
• easy to enhance (I said the same with development time)
• ease of deployment (Bahhh. Releasing and integrating 50-100 microservices couldn't be easier then releasing a single monolith, but different...)
• Single Responsibility (yeah, serve the business logic, provide proper logging and incident handling, integrate with other services, deliver KPI metrics, being resilient, etc...– hahaha....)
• Low impact on other services (due the the SRP in the previous point, I have doubts about how low is the impact when others are depending on it...)
• etc...
