Backend technologies are the key to building robust and scalable applications. They power all platforms and products on the web without even being visible to the users. |
||||
|
||||
While backend programming languages form the foundation of backend development, they aren't enough on their own. Understanding and leveraging the right backend technologies can significantly enhance your development workflow and application performance. |
||||
|
||||
As a [backend developer](https://roadmap.sh/backend), you’ll be faced with too many options while trying to define your backend technology stack, and that can feel overwhelming. |
||||
|
||||
So, in this article, we’re going to cover the best backend technologies in the following categories: |
||||
|
||||
- Databases |
||||
- Version control systems |
||||
- Containerization and orchestration |
||||
- Cloud platforms |
||||
- APIs & Web Services |
||||
- Caching systems |
||||
- Message brokers |
||||
- Authentication and Authorization systems |
||||
- CI/CD |
||||
- Monitoring & Logging |
||||
|
||||
These should help you stay up-to-date or reach the required level to succeed as a backend developer. |
||||
|
||||
## Databases |
||||
|
||||
 |
||||
|
||||
We can’t have a list of backend technologies to learn without covering databases. After all, databases are a core piece of the best backend technologies in use today and the backbone of any application, providing the necessary storage and retrieval of data. Choosing the right type of database depends on your application's requirements, such as data consistency, scalability, and complexity. |
||||
|
||||
### SQL Databases |
||||
|
||||
SQL databases (or relational databases as they’re also called) bring structure to your data and a standard querying language known as SQL. |
||||
|
||||
#### PostgreSQL |
||||
|
||||
PostgreSQL is an advanced open-source relational database known for its reliability and extensive feature set. It supports a wide range of data types and complex queries, making it ideal for applications that require ACID compliance and advanced data handling capabilities. PostgreSQL is commonly used in financial systems, data warehousing, and applications needing strong data integrity and complex reporting. |
||||
|
||||
PostgreSQL also offers robust support for JSON and JSONB data types, enabling seamless integration of relational and NoSQL capabilities within a single database system. Its powerful indexing mechanisms ensure efficient query performance even with large datasets. |
||||
|
||||
Additionally, PostgreSQL provides advanced security features like row-level security and multi-factor authentication, making it a secure choice for handling sensitive data. |
||||
|
||||
#### MySQL |
||||
|
||||
MySQL is a widely used open-source SQL database praised for its speed, reliability, and ease of use. It is particularly popular backend technology for web applications and online transaction processing (OLTP) due to its performance and robust community support. MySQL is often the database of choice for content management systems, e-commerce platforms, and logging applications. |
||||
|
||||
MySQL also supports a variety of storage engines, including InnoDB, which provides ACID compliance, foreign key support, and transaction-safe operations, making it suitable for a wide range of applications. |
||||
|
||||
Its replication capabilities, including master-slave and group replication, ensure high availability and scalability for large-scale deployments. Additionally, MySQL offers advanced security features such as data encryption, user authentication, and role-based access control, enhancing its suitability for handling sensitive data. |
||||
|
||||
#### Microsoft SQL Server |

The three most common types of APIs right now, are REST, GraphQL and gPRC, let’s take a closer look at each one of them. |
||||
|
||||
### REST |
||||
|
||||
REST is a standard architecture for web services, known for its simplicity and scalability. It operates on stateless principles and uses standard HTTP methods (GET, POST, PUT, DELETE) to perform CRUD (Create, Read, Update, Delete) operations. RESTful APIs are typically used to access and manipulate web resources using URLs. |
||||
|
||||
REST is ideal for web applications and services due to its ease of implementation and broad compatibility with various web technologies.

||||
|
||||
**Uniform Interface**: REST APIs follow standard conventions, making them easy to understand and use. This includes using standard HTTP methods and status codes. |
||||
|
||||
**Client-Server Architecture**: Separates the client and server concerns, improving scalability and flexibility. Clients handle the user interface and user experience, while servers handle data storage and business logic. |
||||
|
||||
**Cacheability**: Responses from REST APIs can be cached to improve performance, reducing the need for repeated requests. |
||||
|
||||
**Layered System**: REST allows for a layered system architecture, enabling intermediaries like load balancers and proxy servers to enhance security, performance, and scalability. |

If you’d like to know more about REST, you can read the full definition directly from [its source here](https://ics.uci.edu/~fielding/pubs/dissertation/rest_arch_style.htm). |
||||
|
||||
### GraphQL |
||||
|
||||
GraphQL is a query language for APIs and a runtime for executing those queries by using a type system you define for your data. Unlike REST, where multiple endpoints return fixed data structures, GraphQL allows clients to request exactly the data they need. This flexibility reduces the amount of data transferred over the network and can significantly improve performance. |
||||
|
||||
GraphQL is ideal for applications with complex and dynamic data requirements. |
||||
|
||||
#### Key Characteristics of GraphQL |

> Goal of this project is to teach you how to structure a website using HTML i.e. different sections of a website like header, footer, navigation, main content, sidebars etc. Do not style the website, only focus on the structure. Styling will be done in separate projects. |
||||
|
||||
In this project, you are required to create a simple HTML only website with multiple pages. The website should have following pages: |
||||
|
||||
- Homepage |
||||
- Projects |
||||
- Articles |
||||
- Contact |
||||
|
||||
The website should have a navigation bar that should be present on all pages and link to all the pages. |
||||
|
||||
You are not required to style the website, you are only required to create the structure of the website using HTML. Goals of this project are: |
||||
|
||||
- Learn how to create multiple pages in a website. |
||||
- Structure a website using HTML in a semantic way. |
||||
- Structure in a way that you can easily add styles later. |
||||
- Add SEO meta tags to the website. |
||||
|
||||
You can use the following mockup example to create the structure of the website (remember, you are not required to style the website, only focus on the structure that you can style later): |
||||
|
||||
 |
||||
|
||||
Again, make sure that your submission includes the following: |
||||
|
||||
- Semantically correct HTML structure. |
||||
- Multiple pages with a navigation bar. |
||||
- SEO meta tags in the head of each page. |
||||
- Contact page should have a form with fields like name, email, message etc. |
||||
|
||||
<hr /> |
||||
|
||||
After completing this project, you will have a good understanding of how to structure a website using HTML, basic SEO meta tags, HTML tags, forms etc. You can now move on to the next project where you will learn how to style this website using CSS. |

`Animations` can add visual cues that notify users about what's going on in your app. They are especially useful when the UI changes state, such as when new content loads or new actions become available. Animations also add a polished look to your app, which gives it a higher quality look and feel. |

# ConstraintLayout |

Lets you create large, complex layouts with a flat view hierarchy—no nested view groups. It's similar to `RelativeLayout` in that all views are laid out according to relationships between sibling views and the parent layout, but it's more flexible than RelativeLayout and easier to use. Its available on xml and jetpack compose. |

You can define different named build configurations for your project, such as `development` and `production`, with different defaults. Each named configuration can have defaults for any of the options that apply to the various builder targets, such as `build`, `serve`, and `test`. The Angular CLI can replace files for each environment if you pass a `--configuration` flag with the named configuration when running a CLI command. |

A number of Angular CLI commands run a complex process on your code, such as building, testing, or serving your application. The commands use an internal tool called `Architect` to run CLI builders, which invoke another tool (bundler, test runner, server) to accomplish the desired task. Custom builders can perform an entirely new task or to change which third-party tool is used by an existing command. |

# Creating Libraries |
||||
|
||||
If you have developed features that are suitable for reuse, you can create your own libraries. These libraries can be used locally in your workspace, or you can publish them as npm packages to share with other projects or other Angular developers. Putting code into a separate library is more complex than simply putting everything in one application. It requires more of an investment in time and thought for managing, maintaining, and updating the library. This complexity can pay off when the library is being used in multiple applications. |

# Cross-site Request Forgery |

# Cross-site Request Forgery |
||||
|
||||
Cross-site request forgery, also known as one-click attack or session riding and abbreviated as CSRF or XSRF, is a type of malicious exploit of a website or web application where unauthorized commands are submitted from a user that the web application trusts. There are many ways in which a malicious website can transmit such commands; specially-crafted image tags, hidden forms, and JavaScript fetch or XMLHttpRequests, for example, can all work without the user's interaction or knowledge. Unlike cross-site scripting (XSS), which exploits the trust a user has for a particular site, CSRF exploits the trust that a site has in a user's browser. In a CSRF attack, an innocent end user is tricked by an attacker into submitting a web request that they did not intend. This may cause actions to be performed on the website that can include inadvertent client or server data leakage, change of session state, or manipulation of an end user's account. Angular provides built-in protection against CSRF attacks through the `HttpClientXsrfModule` module. This module automatically adds a token to outgoing requests and validates it on the server side. |

# Cross-site Script Inclusion |

|

Cross-site script inclusion, also known as JSON vulnerability, can allow an attacker's website to read data from a JSON API. The attack works on older browsers by overriding built-in JavaScript object constructors, and then including an API URL using a `<script>` tag. Angular's HttpClient library recognizes this convention and automatically strips the string ")]}',\n" from all responses before further parsing. |

End-to-end or (E2E) testing is a form of testing used to assert your entire application works as expected from start to finish or "end-to-end". E2E testing differs from unit testing in that it is completely decoupled from the underlying implementation details of your code. It is typically used to validate an application in a way that mimics the way a user would interact with it. The `ng e2e` command will first check your project for the "e2e" target. If it can't locate it, the CLI will then prompt you which e2e package you would like to use and walk you through the setup. |

# HttpClient CSRF |

# HttpClient CSRF |
||||
|
||||
HttpClient includes a built-in mechanism to prevent XSRF attacks. When making HTTP requests, an interceptor reads a token from a cookie (default name: XSRF-TOKEN) and sets it as an HTTP header (X-XSRF-TOKEN). Since only code running on your domain can read this cookie, the backend can verify that the HTTP request originates from your client application and not from an attacker. |
||||
|
||||
However, HttpClient only handles the client-side aspect of XSRF protection. Your backend service must be configured to set the cookie for your page and verify that the header is present on all relevant requests. Without this backend configuration, Angular’s default XSRF protection will not be effective. |

Hydration is the process that restores the server-side rendered application on the client. This includes things like reusing the server rendered DOM structures, persisting the application state, transferring application data that was retrieved already by the server, and other processes. Hydration can be enabled for server-side rendered (SSR) applications only. You can enable hydration manually by visiting your main application component or module and importing `provideClientHydration` from `@angular/platform-browser`. |

Angular CLI uses Node and its associated package manager, npm, to install and run JavaScript tools outside the browser. Once you have Node installed, you can run `npm install -g @angular/cli` to install the Angular CLI. |

# Testing services |

# Testing services with dependencies |
||||
|
||||
In an Angular application, Services are responsible for fetching, storing and processing data. Services are singletons, meaning there is only one instance of a Service during runtime. They are fit for central data storage, HTTP and WebSocket communication as well as data validation. |
||||
When you add a dependency to your service, you must also include it in your tests. For isolated tests, pass an instance of the injectable dependency class into the service’s constructor. Using the `inject` function can add complexity. Injecting the real service is often impractical because dependent services can be difficult to create and control. Instead, mock the dependency, use a dummy value, or create a spy on the relevant service method. By using the TestBed testing utility, you can let Angular’s dependency injection handle service creation and manage constructor argument order. |

Therefore, whenever a user requests a HTML Page, firstly HTML page will be rendered and secondly, the angular app will be rendered. The SSG can be used only if your website is static (or) it's content doesn't changes frequently. |

# Template Syntax |

In Angular, a *template* is a chunk of HTML. Use special syntax within a template to build on many of Angular's features. Extend the HTML vocabulary of your applications with special Angular syntax in your templates. For example, Angular helps you get and set DOM (Document Object Model) values dynamically with features such as built-in template functions, variables, event listening, and data binding. |

As for any external dependency, you must mock the HTTP backend so your tests can simulate interaction with a remote server. The `@angular/common/http/testing` library provides tools to capture requests made by the application, make assertions about them, and mock the responses to emulate your backend's behavior. |

# Zone Pollution |
||||
# Zone Pollution |
||||
|
||||
`Zone.js` is a signaling mechanism that Angular uses to detect when an application state might have changed. In some cases, scheduled tasks or microtasks don’t make any changes in the data model, which makes running change detection unnecessary. Common examples are `requestAnimationFrame`, `setTimeout` and `setInterval`. You can identify change detection with Angular DevTools, and you can run code outside the Angular zone to avoid unnecessary change detection calls. |

# Buffer Overflow |
||||
|
||||
A Buffer Overflow is a type of vulnerability that occurs when a program or process attempts to write more data to a buffer—a temporary storage area in memory—than it can hold. This overflow can cause the extra data to overwrite adjacent memory locations, potentially leading to unintended behavior, crashes, or security breaches. |

# Deauth Attack |
||||
|
||||
A Deauthentication (Deauth) Attack is a type of denial-of-service (DoS) attack specific to wireless networks. It involves sending fake deauthentication frames to a Wi-Fi client or access point, forcing the client to disconnect from the network. The attacker uses this technique to disrupt the communication between the client and the access point, often with the intention of capturing data, launching further attacks, or simply causing disruption. |

# Directory Traversal |
||||
|
||||
Directory Traversal, also known as Path Traversal, is a vulnerability that allows attackers to read files on a system without proper authorization. These attacks typically exploit unsecured paths using "../" (dot-dot-slash) sequences and their variations, or absolute file paths. The attack is also referred to as "dot-dot-slash," "directory climbing," or "backtracking." |
||||
|
||||
While Directory Traversal is sometimes combined with other vulnerabilities like Local File Inclusion (LFI) or Remote File Inclusion (RFI), the key difference is that Directory Traversal doesn't execute code, whereas LFI and RFI usually do. |

# Replay Attack |
||||
|
||||
A Replay Attack is a type of network attack where an attacker intercepts and retransmits legitimate communication data, often with the aim of gaining unauthorized access to a system or performing unauthorized actions. In this attack, the attacker captures a valid data transmission and then "replays" it later, without needing to decrypt or alter the data, to trick the recipient into thinking it's a legitimate request. |

# Selection Sort |
||||
|
||||
Selection Sort is a simple and intuitive sorting algorithm. It works by dividing the array into two parts - sorted and unsorted. Initially, the sorted part is empty and the unsorted part contains all the elements. The algorithm repeatedly selects the smallest (or largest, if sorting in descending order) element from the unsorted part and moves that to the end of the sorted part. The process continues until the unsorted part becomes empty and the sorted part contains all the elements. Selection sort is not efficient on large lists, as its time complexity is O(n²) where n is the number of items. |

# Binary Trees |
||||
|
||||
A **Binary Tree** is a type of tree data structure in which each node has at most two children, referred to as the left child and the right child. This distinguishes it from trees in which nodes can have any number of children. A binary tree is further classified as a strictly binary tree if every non-leaf node in the tree has non-empty left and right child nodes. A binary tree is complete if all levels of the tree, except possibly the last, are fully filled, and all nodes are as left-justified as possible. Multiple algorithms and functions employ binary trees due to their suitable properties for mathematical operations and data organization. |

# Binary Search Trees |

|
||||
A **Binary Search Tree** (BST) is a type of binary tree data structure where each node carries a unique key (a value), and each key/node has up to two referenced sub-trees, the left and right child. The key feature of a BST is that every node on the right subtree must have a value greater than its parent node, while every node on the left subtree must have a value less than its parent node. This property must be true for all the nodes, not just the root. Due to this property, searching, insertion, and removal of a node in a BST perform quite fast, and the operations can be done in O(log n) time complexity, making it suitable for data-intensive operations. |

# Tree Traversal |
||||
|
||||
Tree Traversal is a method of visiting all the nodes in a tree data structure. There are three main types of tree traversal, these include Preorder, Inorder, and Postorder. Preorder traversal visits the current node before its child nodes, Inorder traversal visits the left child, then the parent and right child, and Postorder traversal visits the children before their respective parents. There's also a level order traversal which visits nodes level by level. Depth First Search (DFS) and Breadth First Search (BFS) are two popular algorithms used for tree traversal. DFS involves exhaustive searches of nodes by going forward if possible and if it is not possible then by going back. BFS starts traversal from the root node and visits nodes in a level by level manner. |

# Decision Tree Learning |
||||
|
||||
`Decision Tree Learning` is an important concept in game development, particularly in the development of artificial intelligence for game characters. It is a kind of machine learning method that is based on using decision tree models to predict or classify information. A decision tree is a flowchart-like model, where each internal node denotes a test on an attribute, each branch represents an outcome of that test, and each leaf node holds a class label (decision made after testing all attributes). By applying decision tree learning models, computer-controlled characters can make decisions based on different conditions or states. They play a key role in creating complex and interactive gameplay experiences, by enabling game characters to adapt to the player's actions and the ever-changing game environment. |

# Microsurface Scattering |
||||
|
||||
Microsurface scattering, also known as sub-surface scattering, is an important phenomenon in Physically Based Rendering (PBR). This process involves the penetration of light into the surface of a material, where it is scattered by interacting with the material. In other words, when light strikes an object, rather than simply bouncing off the surface, some of it goes into the object and gets scattered around inside before getting re-emitted. It is key to achieving more realistic rendering of translucent materials like skin, marble, milk, and more. Consider it essential for replicating how light interacts with real-world materials in a convincing manner in your game. |
