You’re a system architect looking to expand your skillset. What programming languages should you focus on?

As a system architect seeking to broaden your expertise, consider prioritizing the following programming languages: Python: Renowned for its versatility and readability, widely used in system automation, scripting, and backend development. Go (Golang): Known for its simplicity, concurrency support, and fast execution speed, making it ideal for scalable and reliable systems. JavaScript/TypeScript: Important for scalable web-based systems, leveraging frameworks like Node.js for server-side development. By mastering these languages, system architects can cover a broad spectrum of system design needs, ranging from backend development to web-based applications, ensuring versatility and relevance in the field.

Without being too specific or preferring one language over the other. there are important thing to consider when on programming languages I believe is the ability to integrate with other systems using inbuilt libraries. The community base for the language, the amount of system resources or demand placed on systems by the programming language, a language that support lightweight architectures will be essential.

One of the first things you should look at is the demand and popularity of the programming languages in your market and industry. You want to learn and use languages that are widely adopted, supported, and updated by the community and the vendors. This will ensure that you have access to the latest tools, frameworks, libraries, and best practices that can enhance your productivity and quality. Some of the most popular programming languages for system architecture are Java, Python, C#, C++, and JavaScript. These languages are versatile, powerful, and suitable for various types of systems, such as web, mobile, cloud, embedded

High Demand, High Popularity: This translates to a large pool of developers familiar with them, making them ideal for projects where you need to find talent or integrate with existing systems. High Demand, Niche Popularity: The talent pool might be smaller, their growing demand signifies a future-proof skill to have. Lower Demand, High Popularity: The demand might be more specific to certain project types. Choosing Languages: While "demand and popularity" are important, consider these factors too: Project Domain: If you specialize in a particular area like embedded systems, languages like C or C++ might be crucial. Personal Preference: Some languages have a reputation for being easier to learn (Python) while others offer more control (C++).

As a system architect looking to broaden your skill set, you'd do well to focus on versatile and in-demand languages. Python and JavaScript (or TypeScript for more robust typing) are great for their wide applicability, including web development and automation. Go or Rust are excellent choices for high-performance and scalable systems, offering speed and safety. Finally, consider Java or C# for their strong presence in enterprise environments and robust frameworks, ensuring you can tackle complex architectures effectively. These languages offer a mix of efficiency, scalability, and ecosystem support, making them solid choices for expanding your architectural toolkit.

Domain: Refers to the specific field or area of expertise system will operate in. Problem: Within chosen domain, there's a specific problem to solve with system. For example, in the finance domain, problem might be building a system for high-frequency trading, while in healthcare, it could be developing a system to analyze medical images for early disease detection. Choosing a Programming Language: Different domains often have preferred languages: Certain languages established for specific domains. Python - data science and machine learning; C++ - game development and high-performance computing; Java - enterprise applications. The problem dictates the language's suitability.

When looking at things from a domain and problem perspective, we can see that every domain has a strong preference towards a stack/language. It important here to first ask yourself: Is this the domain/area of expertise I want to be in or specialize at? Once you have that answer, research the language(s) that are most common in that domain and you'll have your answer. There is no "one-size fits all" solution, but the basics you obtain learning different programming languages should still carry over.

Certain languages can significantly enhance decision-making: General-purpose languages: Languages like Python, Java, and C# are versatile and widely used. Understanding their strengths and weaknesses allows you to make informed choices when selecting the right tool for the job. Scripting languages: Languages like Python and JavaScript can be used to automate tasks, write configuration scripts, and prototype functionalities. Domain-specific languages (DSLs): These languages are tailored to specific tasks like data manipulation (SQL) or building automation tools. Understanding a relevant DSL can streamline development in specific domain.

Skill: Project Requirements: The most important factor is the type of systems you'll be architecting. Existing Knowledge: Identify languages you're already familiar with. Building on that base can be faster and more efficient. Preference: Learning Style: Some languages, like Python, are known for their readability and ease of learning. Others, like C++, offer more granular control but have a steeper learning curve. Community and Resources: Languages with larger communities often have more learning resources, tutorials, and online forums for troubleshooting. Industry Trends: Staying updated on popular languages can give an edge in the job market. The ideal scenario is to find a language that aligns with your project needs and interests.

Utilizar uma linguagem da qual você já possui certo domínio, facilita muito as coisas e pode ser fundamental na definição de uma arquitetura complexa, funcional, disponível, escalável e segura.

If you're a few years or more into your career, you may find yourself biased towards a stack or language vs others. This stems from experience and confidence that's been built over time in that particular stack. But don't let that stop you from growing, expanding and getting outside your comfort zone. The next big thing might be just around the corner or on the other side of the fence! Growth happens at the edge of discomfort.

If a systems architect wants to expand their skills by focusing on programming languages, there are several factors to consider, including industry trends. I would keep an eye on the following 2: - Go, a compiled and concurrent programming language developed by Google, designed to be efficient and suitable for building distributed, scalable systems. With the growing interest in cloud-native applications and container-based architectures, Go is becoming increasingly popular among developers and system architects. - Scala, a multi-paradigm programming language that runs on the Java Virtual Machine. With the growing interest in big data-driven systems and distributed computing, knowledge of Scala could be an advantage for a systems architect.

Paradigm Shifts: AI and Machine Learning Integration: AI and ML will be embedded in most systems. Quantum Computing: Understanding its unique programming needs (Q#, Cirq) will position for the future. Prioritization: Security: Languages with strong security features are becoming increasingly important as cyber threats evolve. Cross-Platform Compatibility: Languages that build applications for diverse environments will be valuable. Focus on Concepts: Domain-Specific Languages (DSLs): The ability to understand and potentially create DSLs will be an advantage as these languages become more prevalent for specialized tasks. Low-Code/No-Code Platforms: Grasping the rise of these platforms and their impact on development workflows will be key.

As a system architect you do NOT focus on languages. You pick up a Systems architecture book and a design patterns book. The best are language independent. There may be a language used for exercises, but the ideas should be independent of the language. The language is NOT important in design. You may have some restrictions in choosing the implementation language (e.g., c++ vs Java vs some of the scripting scribbles I cannot call programming languages) depending on how the software needs to be released.

System Architect needs to have basic understanding on behaviors of most of the programming languages. This will help have knowledge on which programming language works well in which conditions. Given that most of the modern systems are micro services, you can go with the polyglot model and use the best of each programming language.

Considerar a finalidade, amplitude do projeto, o valor entregue pela aplicação devem ser fatores decisivos. Recentemente participei do desenvolvimento de um framework mvc para php, onde construí um renderizador de templates, utilizando de algumas funções do php como um projeto de aprendizado profissional. A definição da arquitetura foi o primeiro passo e foi bastante desafiador. Um framework leve, simples e de fácil aprendizagem. Totalmente open source para os jovens que queiram dar o primeiro passo.

The language you pick is not very important. I would pick whatever your organization is using, and insist on participating in coding for real world problems. If you can't contribute to the actual product, contribute to testing environments or test setups or whatever, as long as you face actual real life problems.
