A Domain Specific Language (DSL) is a programming language that’s dedicated to a particular problem domain. DSLs are often used to support domain-drive design and modelling. It’s the opposite of general purpose programming languages such as C# or Java.
- Code looks like domain prose.
- Easier to understand by everyone.
- Easier to align with requirements.
- More succinct (so less code is required!).
- Hard to design, test and debug.
- Bad API designers make even worse DSL designers!
- Different people use different terminologies (think mobile in the UK and ‘cell’ in the US) which reduces DSL’s ability to bridge gaps in communication.
- Industry specific, so from a career and personal development point of view, it’s not attractive to me to specialize myself in DSLs and be locked into one industry.
- Existing expertise and talent is hard to find (compared to general purpose languages).
- Additional training required for people new to the industry.
I specialise in rapidly transitioning teams to serverless and building production-ready services on AWS.
Are you struggling with serverless or need guidance on best practices? Do you want someone to review your architecture and help you avoid costly mistakes down the line? Whatever the case, I’m here to help.
Check out my new course, Complete Guide to AWS Step Functions. In this course, we’ll cover everything you need to know to use AWS Step Functions service effectively. Including basic concepts, HTTP and event triggers, activities, callbacks, nested workflows, design patterns and best practices.
Here is a complete list of all my posts on serverless and AWS Lambda. In the meantime, here are a few of my most popular blog posts.
- Lambda optimization tip – enable HTTP keep-alive
- You are thinking about serverless costs all wrong
- Many faced threats to Serverless security
- We can do better than percentile latencies
- I’m afraid you’re thinking about AWS Lambda cold starts all wrong
- Yubl’s road to Serverless
- AWS Lambda – should you have few monolithic functions or many single-purposed functions?
- AWS Lambda – compare coldstart time with different languages, memory and code sizes
- Guys, we’re doing pagination wrong
