There are a few qualities that differentiate average from high performing software engineering organisations. I believe that attitude towards the design of code and architecture is one of them. Martin Fowler argues that internal quality of a software system enables new features and improvements to be delivered more sustainably.

As the pace of business quickens, software development has adapted. Increasingly, teams release software features more quickly to accommodate customer needs. As a result, organizations are weighing microservices vs. monolithic architecture to improve software delivery speed and quality. What is monolithic architecture?

Most organisations go through an architecture modernisation effort at some point as their systems drift into a state of intolerable maintenance costs and they diverge too far from modern technological advances. This means a software architecture should be purposely designed for the most favourable business consequences.

The need for systems to be resilient is still increasing, and chaos engineering tools and techniques are developing as a key way to validate that resilience is working as designed.

It’s easy to imagine a lot of software professionals saying, “Of course you’ll have to know C.

Example: if you have replication factor as 3, i.e. 3 nodes are going to have exact same copy of your data, write CL as QUORUM, i.e. you are going to write to majority or 2 nodes and read CL as QUORUM, i.e. you are going to read from majority or 2 nodes, then you can see from the formula that you are going to have immediate consistency.

Technology systems are difficult to wrangle. Our systems grow in accidental complexity and complication over time.

Modernizing an architecture usually take years. Even a decade or more is nothing out of the ordinary for large organizations who have accumulated legacy and heritage systems over long periods of time.

How do we break a large system into smaller, more manageable modular components? In Domain-Driven Design, a large system is decomposed into bounded contexts , which become natural boundaries in code as microservices and as teams in the organisation. Both a wide and deep knowledge of the business and domain is essential.

Let's talk about the elephant in the room; Serverless doesn't really mean that there are no Software or Hardware servers. It just means that from Software Development perspective, servers are abstracted and outsourced to another entity, so you don't need to worry about it. Serverless systems are still in their infancy.
