The Trends #1: Software Development Trends 2023/2024 - Vol. 1.

At the start of 2024. we will look at the summary of important software development trends we observed in 2023. that will probably follow us in 2024. too. This will be the first of two newsletter issues on this topic.

In this issue, we will review the following:

• Software Architecture InfoQ Trends Report 2023.

• Stack Overflow Developer Survey 2023.

• 2023 State of the API Report by Postman

• ThoughtWorks Technology Radar - Volume 29.

• The State of Developer Ecosystem 2023 by JetBrains

So, let’s dive in.

Postman Collections (Sponsored)

Postman Collections enable exceptional API organization. Postman Collections are groups of saved API requests that can be shared with others. These requests may represent a specific workflow, and they may also function as an API test suite. With collections, you can link related API elements together for easy editing, sharing, testing, and reuse.

Software Architecture InfoQ Trends Report (April 2023.)

In the latest report by InfoQ, we got some new insights on Software Architecture and Design:

• Design for Portability is becoming more popular as architects can decouple business logic from implementation details because frameworks like Dapr emphasize a cloud-native abstraction model.

• Large language models will significantly influence, from enabling a new generation of low-code and no-code developers to understanding architectural trade-offs.

• In the upcoming years, the Sustainability of software will be a crucial design factor. As a result, improvements are being made to how the carbon footprints of software systems are measured and then reduced.

• Architects constantly seek ways to document better, explain, and comprehend decisions. Large language models might also be used in this field, functioning as forensic archaeologists to search through ADRs and git histories.

Also, some exciting changes to the graph: Serverless is now in the Late Majority, while Architecture Design Records (ADRs) entered the Early Majority. Modular monoliths are still a part of the Early Majority group.

2023 State of the API Report by Postman (June 2023.)

More than 40,000 API professionals and developers were polled about issues like development priorities, API tools, and the future of APIs. The questions were updated this year to include pertinent information on API monetization and generative AI.

Here are the key findings:

1. APIs are a moneymaker for most - Nearly 2/3 of respondents claim that their APIs bring in money. 43% of the respondents stated that their APIs account for over a quarter of their business's income. Revenue was crucial in the financial services and advertising industries. It was ranked as the No. 2 indicator of a successful public API right after usage.

2. API pricing increasingly matters - Price is the primary factor, according to 47% of respondents, when determining whether to integrate with an API. In each of the previous two years, that number was 41% lower. Although other variables were given a higher priority, this result may indicate that API consumers are becoming more cost-conscious in the wake of the industry's downturn.

3. Most API professionals use AI To help with coding - Sixty percent of respondents claim to employ generative AI. Over half of them use it to identify faults in their code, and more than a third use AI to create new code. Building AI-powered apps came in first when developers were asked what kind of project they were most excited about in the upcoming year.

4. The outlook for API investment has brightened - Ninety-two percent of respondents—up from 89% last year—say that investments in APIs will increase or remain unchanged over the next 12 months. This growth may indicate that some people believe the worst of the technological sector's economic decline is behind us. However, fewer respondents anticipate reducing API investments this year.

5. API security is improving, but some sectors have work to do - For most responders, API security has improved, and incidents will happen less frequently in 2023. But certain industries performed worse than others. Participants in the poll said that monthly events happened at higher rates than normal in the automotive, educational, and retail sectors.

6. The number of API-first leaders swells by almost half - An increase from 8% in each of the previous two years to 11% of respondents who identified as leaders who prioritize APIs. This exclusive group performs exceptionally well across practically all metrics, including how rapidly APIs can be produced and quickly recovered after an API failure.

ThoughtWorks Technology Radar - Volume 29. (September 2023.)

In the latest Technology Radar released in September by ThoughtWorks, we saw different themes emerging:

1. AI-assisted software development: AI-related topics dominated the conversation. There's a significant interest in using AI to assist in software development. Tools like GitHub Copilot, Tabnine, and Codeium were discussed. There's also excitement about open-source LLMs for coding.

2. How productive is measuring productivity? The industry has moved away from using lines of code as a measure of output. Instead, the focus is on engineering effectiveness. Tools such as DX DevEx 360 address this by focusing on the developer experience.

3. A large number of LLMs: Large language models (LLMs) form the basis for many modern breakthroughs in AI. The core competing ecosystems like OpenAI's ChatGPT, Google's Bard, and others were discussed.

4. Remote Delivery workaround matures: The pandemic's impact solidified complete remote or hybrid work as an enduring trend. Remote software development practices and tools have developed, with teams focusing on effective collaboration in a more distributed environment.

Techniques

• Adopt: Design systems and a lightweight approach to RFCs.

• Trial: Accessibility-aware component test design, attack path analysis, automatic merging of dependency update PRs, and data product thinking for FAIR data, among others.

• Assess: Dependency health checks to counter package hallucinations, design system decision records, GitOps, and more.

• Hold: Ignoring OWASP Top 10 lists and web components for server-side-rendered (SSR) web apps.

Tools

• Adopt: debt, Mermaid, Ruff, Snyk

• Trial: AWS Control Tower, Bloc, cdk-nag, Checkov, etc.

Platforms

• Adopt: Colima is an alternative for Docker on macOS.

• Trial: CloudEvents, DataOps. live, Google Cloud Vertex AI, Immuta, etc.

Languages and Frameworks

🔹 Adopt: Playwright
🔹 Trial: .NET Minimal API, Ajv, Armeria, AWS SAM, etc.
