Unraveling the 5 Layers of Software Development

In the realm of software development services, every application is built upon a foundation of interconnected layers, each serving a specific purpose in delivering functionality to end-users. Understanding these layers and the technologies that power them is crucial for developers aiming to create robust and efficient software solutions. In this blog, we'll explore the five key layers of software architecture: User Interface (UI), Application Programming Interface (API), Database (DB), Business Logic, and Hosting, along with examples of technologies commonly used in each layer.

User Interface (UI): The UI layer is what users interact with directly. It encompasses everything from the visual design to the user experience (UX). Technologies used in this layer focus on creating intuitive, responsive, and aesthetically pleasing interfaces. Some popular UI Design technologies include:

HTML/CSS/JavaScript: These front-end technologies form the backbone of web-based UIs. HTML defines the structure, CSS styles the elements, and JavaScript adds interactivity.

React.js/Vue.js/Angular: These JavaScript frameworks are used to build dynamic and interactive user interfaces for web applications.

Swift/Kotlin: For mobile application development, languages like Swift (for iOS) and Kotlin (for Android) are used to develop native user interfaces.

Application Programming Interface (API): The API layer acts as an intermediary between the UI and the business logic, enabling communication and data exchange. APIs define the endpoints and protocols through which different software components interact. Common technologies used in API development services  include:

RESTful APIs: Representational State Transfer (REST) is a popular architectural style for designing networked applications. RESTful APIs use HTTP methods like GET, POST, PUT, and DELETE to perform operations on resources.

GraphQL: An alternative to REST, GraphQL provides a more flexible and efficient approach to querying and manipulating data. It allows clients to request only the data they need, reducing over-fetching and under-fetching.

Express.js/Django/Rails: Frameworks like Express.js (for Node.js), Django (for Python), and Rails (for Ruby) are commonly used to build web APIs quickly and efficiently.

Database (DB): The database layer is responsible for storing, retrieving, and managing data. It provides a persistent storage solution for an application's information. Various types of databases exist, including relational databases, NoSQL databases, and in-memory databases. Some popular database technologies include:

MySQL/PostgreSQL: Relational database management systems (RDBMS) like MySQL and PostgreSQL are widely used for structured data storage and management.

MongoDB: A popular NoSQL database, MongoDB is designed for storing unstructured or semi-structured data in JSON-like documents.

Redis: An in-memory data structure store, Redis is often used as a caching layer or for real-time data processing.

Business Logic: The business logic layer contains the application's core functionality and rules. It processes requests from the UI, interacts with the database, and performs the necessary operations to fulfill user actions. While business logic can be implemented in various programming languages, some technologies commonly used for this layer include:

Java/C#: Object-oriented languages like Java and C# are often chosen for building robust and scalable business logic components.

Node.js/Python: JavaScript (with Node.js) and Python are also popular choices, especially for applications requiring agility and rapid development.

Spring/.NET Core: Frameworks like Spring (for Java) and .NET Core (for C#) provide tools and libraries for building enterprise-grade business logic components.

Hosting: The hosting layer encompasses the infrastructure and environment where the application runs. It includes servers, cloud platforms, containers, and other deployment options. Popular hosting technologies and platforms include:

Amazon Web Services (AWS)/Microsoft Azure/Google Cloud Platform (GCP): These cloud service providers offer a range of hosting solutions, including virtual machines, containers, and serverless computing.

Docker/Kubernetes: Containerization technologies like Docker and orchestration platforms like Kubernetes provide efficient ways to package, deploy, and manage applications across different environments.

Heroku/Netlify/Vercel: These platforms offer simplified hosting solutions specifically tailored for web applications, providing features like continuous deployment, scalability, and managed infrastructure.

In conclusion, navigating the various layers of software architecture requires a comprehensive understanding of each layer's purpose and the technologies that power them. By leveraging the right technologies for UI, API, DB, logic, and hosting, developers can build robust, scalable, and maintainable software solutions that meet the needs of modern users and businesses.

api の JSON 形式コンテンツの分散データベース一般形式は生まれないだろうか

分散台帳的なもの。 Gitrepositoryとかdocker のrepisotiryはマスターにいてもどこにいてもいいし、グラフ形状で配られた（ネットワーク的に配られた）どのマシンにも住んでいられる。マスターという概念はあるものの、優れたグラフ（ツリーではなくグラフ）と差分と解決のプロセスでデータを維持できてる。

Restは基本的にdbとかのドメインモデルに概念的には根ざしており、またその上に垂直にスタックを積むことで一種の強度を得ていて、それゆえ特に破壊的操作の時に分散に対して弱い。

Graphqlやapiのcdnにおけるキャッシュのイメージは近いのだが、BFFs��ターンみたいにマイクロサービスの前哨基地として、ロジックコードなどもコンテナなど仮想化されポータルブルになっている環境に置いて配られ、ユーザーのスマートフォンや、コンピュータ、ブラウザの中にコンテナが配られ、そしてデータも配られていて、フロントエンドはそのローカルにあるサーバー内に対して通信→BFFがロジックも含めて応答→localの分散データ基盤のmodelにsaveする→分散による差分問題などを解消はマークしていかねばならないが問題がなく解決できる場合はバックエンド、というよりは「マスター」にデータを渡す。

や、えーとね、オフラインモードとかを実装しているウェブあぷも出てきてるんよ。workflowyとかnotionとかasanaとか。local storageなのかなんかにデータ保存してる。あるいはreactやpolymerたちなどもやろうと思えば結構簡単にデータを潜ませておいて通信あったら頑張るってことはできるんだが、これはvirtual dom使っていたりする。ので、データの形式的にはjsonがuniversalになった今では、restにこの分散を管理する能力と仕様、そしてhttpの次バージョンなどでそういうものもできてきたら超やばいなと思う。同期が可能になる。 Icloudやfirebaseやmbaasなどその方向に向かいそうな気配がする仕組みなどなどはできてきてるしcloudfrontとかもっと次行ったら行くんじゃねーかって感じもする（というかユーザーのマシンの中にcloudfrontインスタンスがdocker経由で走るみたいな時代にならないかなー）

これとpwaあたりとjs爆速実行armとかで揃ってくると 再びnativeよりweb 技術で統一だって時代くんじゃねーの感

あとetag/last modified をめちゃ小さく通信したり先に通信しとくみたいなことも http の次の標準には入ってほしい。脳みそとかそういうことしてそうだし（調べてないけど）。super preflightとか predictive flightみたいなもん

いきなりどエンジニアリングトークになってしまい結構非技術者にフォローと購読されているらしいので爆撃じみてしまったが構わないことにする。

GraphQL API from an RDBMS Connection (leveraging the DB's metadata), with focus on simplicity. CRUD: tables and/or views become queryable as root objects including nested objects of n-ary relationships with aggregation, filter, sorting and pagination supported. Mutations (create, update and delete) are also created per table. Customizable processing via interceptors - configured per table & operation type and at pre/post DB operations. Tries to create a single SQL joining multiple tables when necessary. It comes with a demo project you can explore. Currently supports SQLite and PostgreSQL.

Aggregate Functions in Stargate’s GraphQL API

Aggregate Functions in Stargate’s GraphQL API

A new release of Stargate.io was applied to Astra DB that includes an exciting new feature: aggregate functions! If you’re not familiar with aggregate functions, they are functions that look at the data as a whole and perform a function like min(), max(), sum(), count() and avg(). Until now, aggregate functions were only available using cqlsh (the CQL Shell). However, with the Stargate 1.0.25…

11 Dịch vụ AWS Serverless xịn nên sử dụng trong kiến trúc cloud

Có bài viết học luyện thi AWS mới nhất tại https://cloudemind.com/aws-serverless-services/ - Cloudemind.com

11 Dịch vụ AWS Serverless xịn nên sử dụng trong kiến trúc cloud

Serverless services là những dịch vụ thuộc dạng fully managed services có nghĩa là mọi thứ liên quan đến hạ tầng underlying hardware, provision, maintenance, patching, hay thậm chí cao hơn về bảo mật sử dụng cũng được AWS làm sẵn cho mình. Serverless có thể gọi là lý tưởng cho các developer thay vì nỗi lo về máy chủ cấp phát, cấp phát có thừa hay quá thiếu hay không, sau khi đưa vào sử dụng có cần phải update, upgrade patching gì không (Đây thực sự là ác mộng với các bạn developer mà ko rành về hạ tầng, về CLI, shell này nọ).

AWS hiểu được điều này và offer một số dạng dịch vụ gọi là serverless như thế.

Serverless là gì?

Serverless dịch Tiếng Việt là “Phi máy chủ” nhưng dịch ra có vẻ hơi ngớ ngẩn, mình cũng không biết dịch sao cho thoát nghĩa. Serverless không phải là không có máy chủ theo nghĩa đen, bản chất của serverless nằm lớp bên dưới vẫn là các máy chủ, nhưng AWS làm cho việc này một cách mờ đi (transparency hay invisibility) và tự động quản lý vận hành lớp hạ tầng này miễn sao cung cấp đủ capacity như thiết kế cho bạn.

AWS Serverless

Definition of serverless computing: Serverless computing is a cloud computing execution model in which the cloud provider allocates machine resources on demand, taking care of the servers on behalf of the their customers – Wikipedia

Serverless refers to applications where the management and allocation of servers and resources are completely managed by the cloud provider. – Serverless-Stack

Serverless is a cloud-native development model that allows developers to build and run applications without having to manage servers. There are still servers in serverless, but they are abstracted away from app development. – Redhat

Kevin tập trung vào việc phát triển các product sử dụng Cloud Native cho nên luôn ưu tiên các dịch vụ Serverless trong kiến trúc của mình để tăng tốc độ phát triển, dễ dàng scaling, và chi phí cũng rẻ hơn rất nhiều so với cách làm Cloud truyền thống.

Nào, mình cùng điểm qua các dịch vụ AWS Serverless hiện có nào:
