Check out my new course Learn you some Lambda best practice for great good! and learn the best practices for performance, cost, security, resilience, observability and scalability.
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, Learn you some Lambda best practice for great good! In this course, you will learn best practices for working with AWS Lambda in terms of performance, cost, security, scalability, resilience and observability. Enrol now and enjoy a special preorder price of £9.99 (~$13).
Are you working with Serverless and looking for expert training to level-up your skills? Or are you looking for a solid foundation to start from? Look no further, register for my Production-Ready Serverless workshop to learn how to build production-grade Serverless applications!
