For this blog entry, I chose to review the blog “Software Licensing – Terms and Licenses Explained” by CrystalLabs because software licensing connects to what we’ve been learning and working with in class. The blog explains what software licensing is, how it works, and why choosing the right license is essential for developers and organizations. It also covers the differences between proprietary software, open-source software, and other license types that decide whether people can modify or redistribute code. This ties directly into our course discussions on ownership, copyright law, and the responsibility developers have when sharing their work.

The blog begins by defining a software license as a legal agreement that outlines how software can be used, shared, or changed. Proprietary software licenses are restrictive, stopping users from seeing source code or redistributing the program. Most commercial software uses this model. The blog then explains that open-source software gives users more freedom, but the level of freedom depends on the specific license. Permissive licenses like MIT or BSD allow people to reuse the code in pretty much any way they want, including in commercial applications. Copyleft licenses like GPL require that any modified version remains open-source under the same license, protecting long-term openness. The blog also briefly touches on public-domain software, where the creator essentially gives up all rights.

I selected this resource because software licensing is something that is extremely important but I didn’t fully understand. Since we are studying software licensing in class, learning how and when I can use someone else’s code is crucial. It isn’t just about making software work, developers must consider legal compliance and respect for the original author’s intentions.

What stood out to me was how much power a license has over the future of a project. One document can determine whether software becomes a community project or remains locked behind a licensing wall. Now I understand that licenses shape the project itself, being an essential part of the start of any work. This made me more aware for future software that I work on later down the line, I will need to purposely choose a license that matches my goals.

Overall, this resource helped me better understand software licensing as something tied to ethics, law, and user rights. I’m definitely more prepared to navigate licensing in my future work, the software I use and create will be properly licensed with this knowledge in mind.

For this week’s blog post I wanted to go with the “Backends for Frontends” (BFF) architecture pattern through Microsoft Azure’s documentation(https://learn.microsoft.com/en-us/azure/architecture/patterns/backends-for-frontends), having read the article in-depth since it gave me some food for thought.

The article explains how BFF works as an API design approach where each type of client; such as a web application, mobile app, or IoT device kind of communicates with its own tailored backend service. Instead of one universal backend trying to serve every kind of client, BFF splits the responsibilities across dedicated backend components. This lets each frontend receive data in exactly the structure and format it needs, without unnecessary complexity or over-fetching. The article also describes when BFF is useful, the problems it solves (like avoiding “one-size-fits-all” backend design), and its trade-offs, such as increased cost and operational overhead.

I guess I chose this resource considering how BFF connects directly to what we’ve been doing in CS-343 with REST APIs, Express endpoints, data validation using OpenAPI, and separating layers of an application. During the recent advanced assignment(referring to the REST API Back End Implementation homework of course), I had to build new endpoints, interact with multiple collections, and send changes to a message broker. That required some time of me thinking carefully about how different parts of the system communicate with each other.

The biggest takeaway for me was how the BFF pattern embraces specialization. Instead of making one giant backend do everything, you just got to let each client have a backend that fits them. This avoids exposing unnecessary fields, reduces client-side processing, and improves performance. It also aligns well with microservices, because each BFF can orchestrate multiple services behind the scenes. I realized that the structure of our assignments- frontend consuming API endpoints, backend handling logic, and MongoDB representing the persistence layer; is essentially a simplified version of this architectural thinking.

This article also made me reflect on situations where BFF might solve real problems i could probably encounter in the near future. For example, in our backend assignment, if we had a separate mobile client, its data needs would be very different from the web interface that interacts with full guest objects. A BFF layer could format responses appropriately, avoid over-fetching, and simplify the logic on the client side. The idea of tailoring backends to frontends also helps me make sense of why large systems separate responsibilities; it keeps things maintainable and avoids tightly coupled components.

So in short, i’d say that this resource strengthened my understanding of how backend architecture is shaped by client needs. It also helped me see the bigger picture behind concepts we’ve been using: validation, routing, endpoint design, and database access. Going forward, I expect this perspective to help me structure backend code more intentionally, especially when designing APIs that may evolve to support multiple types of clients.
