Infrastructure

Frameworks simplify development, eliminate chaos, and provide a clear structure when building an application.

Each framework comes with a specific set of ready-made tools—battle-tested technical solutions that accelerate and simplify development.

In this article, we’ll take a look at the 10 most popular backend frameworks for 2025—essential tools for nearly every modern application.

Server Framework Tasks

Typically, any server-side application performs a set of standard functions:

  • Routing. Handling user requests via a REST API.
  • Authentication. Managing user registration and login.
  • Logic. Implementing the core server logic: generating page content, managing carts, handling messages, etc.
  • Storage. Connecting to a (remote) database to write, read, and sort data.
  • Payments. Processing payment transactions.
  • Extensions. Supporting third-party software (libraries and frameworks) required for managing external devices: smartphones, personal computers, servers, etc.
  • Microservices. Communicating with remote applications (such as microservices) via REST API.

A good backend framework should satisfy all the above requirements, ensuring functionality, security, and performance in the final product.

1. ASP.NET Core

ASP.NET Core is a cross-platform framework developed by Microsoft for building modern web applications and APIs. It works with the C# programming language and runs on Windows, Linux, and macOS.

Importantly, ASP.NET Core is not the same as ASP.NET Framework. It is its evolutionary successor: a modern, modular, cross-platform solution.

  • Modularity. Uses only the necessary components, making the application lightweight and flexible.
  • Support. Actively maintained and updated by Microsoft, ensuring access to new features, bug fixes, and security improvements.
  • Tooling. Integrates with modern development tools like Visual Studio and Visual Studio Code.

Audience

Thanks to its flexibility, ASP.NET Core is suitable not only for web development with its client-side services but also for mobile apps and games that require complex backend logic and fast database interactions.

However, despite its cross-platform nature, ASP.NET Core remains more focused on Windows developers and users.

The framework is especially beneficial for large enterprises and corporate developers who need to build scalable, high-performance, and fault-tolerant applications and microservices with a clear and strict architecture.

Code

Example of a basic routing setup in ASP.NET Core using the MVC template:

Model:

app.UseEndpoints(endpoints =>
{
	endpoints.MapControllerRoute(
		name: "default",
		pattern: "{controller=Home}/{action=Index}/{id?}");
});

Controller:

public class BooksController : Controller
{
	public IActionResult Details(int id)
	{
		ViewBag.Id = id;
		return View();
	}
}

View:

@{
	ViewData["Title"] = "Details";
	int id = ViewBag.Id;
}

<h1>Details</h1>
Book Id : @id

2. Django

Django is a free, high-level framework written in Python that also follows the MVC design pattern.

It’s a modular framework that heavily emphasizes the “Don’t Repeat Yourself” (DRY) principle, which helps reduce code redundancy and simplify maintenance.

Each Django project consists of multiple apps that can be developed and tested independently. This allows for easy reuse across different projects.

A key feature of the framework is its Object-Relational Mapping (ORM) tool, which allows developers to manage relational databases using only Python code—no SQL required.

At the same time, Django is also scalable enough to support enterprise-level solutions.

Code

A snippet of Django code for routing user requests:

from rest_framework import routers
from collaborativeAPP import views

router = routers.DefaultRouter()

router.register(r'get_one', views.OneViewSet)
router.register(r'get_two', views.TwoViewSet)
router.register(r'get_three', views.ThreeViewSet)

urlpatterns = patterns(
	...
	url(r'^service/', include(router.urls))
)

3. Laravel

Laravel is a popular PHP framework for building web applications that follows the MVC design pattern.

It’s known for its clear syntax, the Blade templating engine, and the built-in task automation tool Artisan CLI.

{
    return 'Foo and Bar';
});

Route::get('user/{id}', function($id)
{
    return 'User '.$id;
});

4. Ruby on Rails

Ruby on Rails (or simply Rails) is a popular web development framework written in Ruby that provides a ready-made structure for writing code. 

Its main feature is the “Convention over Configuration” principle, which radically changes the way web apps are developed by making it more intuitive and productive.

  • Security. Includes built-in security features like protection against SQL injection, XSS, CSRF attacks, and more.

Audience

The main draw of Ruby on Rails is development speed. It’s perfect for those who need to rapidly prototype and validate new features.

Sometimes, using an off-the-shelf CMS can either overcomplicate or limit your project’s flexibility. In such cases, Rails lets you easily build a custom engine for your web app with minimal effort.

Code

A simple example of a Rails controller for displaying articles:

class ArticlesController < ApplicationController
	def index
		@articles = Article.recent
	end

	def show
		@article = Article.find(params[:id])
		fresh_when etag: @article
	end

	def create
		article = Article.create!(article_params)
		redirect_to article
	end

	private
		def article_params
			params.require(:article).permit(:title, :content)
		end
end

5. Express.js

Express.js is the most popular (and possibly the best overall backend framework) minimalist web framework on the Node.js platform, used to create flexible HTTP servers using RESTful APIs.

How to Host an ARK Server: Detailed Guide

Have you ever wondered why ARK: Survival Evolved is so popular among the masses? The question is simple - the world is massive, the challenges are tough, and teaming up with friends brings it all to life. But what if you're tired of lag, trolls, or losing progress on shared public servers? This is why you need to host your own ARK dedicated server. In this tutorial, you'll learn how to host an ARK server on your own machine or through a cloud provider like Hostman. We'll walk through everything you need—from setup to launch. Ark: Survival Evolved servers list Key Takeaways A dedicated ARK server gives you full control over settings, players, mods, and performance. You can host your own ARK server on Windows or Linux using SteamCMD. ARK servers require solid hardware—at least 16 GB RAM and a fast CPU are recommended. Hosting through cloud providers like Hostman can simplify setup and improve uptime. With the right configuration, your ARK server can run smoothly, even with custom maps and mods. What Is an ARK Dedicated Server? An ARK dedicated server is a private environment where your game world runs independently of the default multiplayer options. Instead of relying on Studio Wildcard’s shared servers, you run your own—from your PC or a remote cloud instance. That means you can control the experience all by yourself, only limited by your own morals. You can host PvE or PvP sessions, manage mods, control who joins, and set your own rules. For groups that want a consistent, customizable experience, it’s the best way to play. Benefits of Playing ARK: Survival Evolved Online While ARK is a good game for solo leveling experience, the game truly shines in multiplayer. Building a base, taming dinosaurs, and exploring tropical maps becomes even more rewarding with others. Here’s why: Shared workload: More fun when you play with your friends. Faster progression: Gather resources, craft tools, and level up faster in cooperation with friends. Social connection: It's more fun to build, battle, and explore. PvP opportunities: Challenge others in combat or form alliances. Knowledge sharing: Let the new players learn quickly from experienced survivors. Multiplayer isn't just about more people—it's about better gameplay, deeper strategy, and shared stories that keep you coming back. Why Do You Need an ARK Dedicated Server? It’s not always useful to rely on public servers since they can lead to a traumatizing experience in ARK: Survival Evolved. A lot of external factors can ruin your game session, among them—lags, cheaters, trolls, server wipes. If you choose to run your own ARK server you become more worry-free of these problems if you have a desire to play peacefully. You can set your own rules, choose who gets access, and configure performance settings based on your needs. Want to tame dinos faster? Adjust the multipliers. Prefer PvE over PvP? You decide. Plus, your game world will stay active even when you’re not logged in. Hosting your own server (especially with Hostman’s VPS Server) helps you to stop relying on your own (or someone elses) hardware, which is often the case in peer-hosted multiplayer games. It can be frustrating when the host logs out or their machine crashes, meaning that session ends for everyone. A dedicated setup avoids this entirely. An example of how to setup your own rule on Ark dedicated server How To Setup an ARK Game Server: Detailed Guide Setting up an ARK dedicated server is pretty simple. Let’s show you some useful steps. Step 1: Prepare Your Server Before anything else, make sure your system meets the recommended ark server requirements: CPU: Quad-core, 3.5 GHz or higher RAM: At least 16 GB (more if using mods) Storage: 50 GB SSD minimum Upload Bandwidth: 20 Mbps+ You can use Windows or Linux, but many prefer Linux for its stability and lower resource consumption. Make sure your OS is 64-bit and kept up to date. Step 2: Install SteamCMD SteamCMD is the command-line tool used to install game server files. To install SteamCMD on Linux: sudo apt update && sudo apt install steamcmd On Windows: Download SteamCMD from the official site. Extract it to C:\steamcmd. Run steamcmd.exe. Step 3: Install ARK Server Files Create a folder for the ARK server installation: mkdir ark-server && cd ark-server Launch SteamCMD and download the ARK server using the anonymous login: steamcmd +login anonymous +force_install_dir ./ark-server +app_update 376030 validate +quit Use 2430930 if you want to install ARK: Survival Ascended instead of the classic version. Step 4: Configure the Server Once installed, navigate to: cd ark-server/ShooterGame/Saved/Config/LinuxServer/ Or on Windows: C:\ark-server\ShooterGame\Saved\Config\WindowsServer\ Create and edit these two files: GameUserSettings.ini Game.ini Basic settings to add: [ServerSettings] ServerAdminPassword=YourAdminPass ServerPassword=OptionalPlayerPass SessionName=HostmanARKServer Add any gameplay tweaks here as needed (e.g., dino taming speed, resource multipliers). Step 5: Open Required Ports Make sure your firewall and hosting provider allow traffic through these ports: UDP 7777 – Game port UDP 27015 – Query port UDP 27020 – RCON port (optional) On Linux: sudo ufw allow 7777/udp sudo ufw allow 27015/udp sudo ufw allow 27020/udp Step 6: Start the ARK Server You can launch the server using a startup script.  For Linux: ./ShooterGame/Binaries/Linux/ShooterGameServer TheIsland?SessionName=HostmanARKServer?ServerPassword=MyPass?ServerAdminPassword=MyAdminPass?listen -server -log For Windows, create a batch file like this: start ShooterGameServer.exe TheIsland?SessionName=HostmanARKServer?ServerPassword=MyPass?ServerAdminPassword=MyAdminPass?QueryPort=27015?Port=7777?listen Double-click the .bat file to start your server. Step 7: Join Your ARK Server To connect: Launch ARK: Survival Evolved Click Join ARK Set filter to Unofficial Search your server name or IP address If your server doesn’t appear, go to Steam → View → Servers → Favorites and manually add: your.server.ip:27015 Now you’re ready to enter your world! Conclusion Running your own ark dedicated server gives you full control over your ARK: Survival Evolved experience. This is way better if you want to dedicate your precious time to your beloved game, where you want to build a small and warm community of players. If you're just getting started, consider launching your ARK server on a reliable cloud provider. A VPS from Hostman, for example, allows you to scale resources as your community grows, while enjoying a simplified deployment process and responsive support. FAQ What are the minimum ARK server requirements? For smooth gameplay, your server should have at least a quad-core CPU (3.5 GHz or higher), 16 GB of RAM, and an SSD with 50 GB or more of free space. A stable internet connection with at least 20 Mbps upload speed is also essential. Can I host an ARK server on my own PC? Yes, you can self-host an ARK server from your own machine, but this works best for small groups and limited sessions.  How many players can join my ARK dedicated server? The player limit depends on your hardware and internet bandwidth. With proper specs (16 GB RAM and above), you can comfortably support 10–30 players. Is hosting an ARK server free? You can host it for free on your own hardware, but you’ll cover electricity, bandwidth, and maintenance costs.

What is GitOps and How to Use it?

GitOps is a new way of managing cloud infrastructure and deploying applications. Built on some familiar and recognizable developer workflows, GitOps helps you automate infrastructure changes, improve system reliability, and simplify continuous delivery. In this tutorial, you’ll learn what GitOps is, how it works, the tools behind it, and how to implement a GitOps pipeline using Kubernetes and Hostman-compatible workflows. GitOps working scheme Key Takeaways GitOps uses Git as the single source of truth for infrastructure and deployment. It relies on declarative configurations and automatic reconciliation. GitOps enables auditability, rollback, and faster deployments. It works particularly well with Kubernetes and cloud-native environments. Tools like Argo CD, Flux, and Helm are commonly used in GitOps pipelines. What Is GitOps? GitOps is a set of practices that uses Git repositories to manage both application code and infrastructure configurations. With its help, developers can get rid of using traditional manual revisions or ad hoc scripts, GitOps relies on Git as the authoritative source for your system’s desired state. This means your cluster configuration, deployment manifests, Helm charts, and more are stored and managed within a single Git repo. So, when you need to update infrastructure or release a new application version, you simply commit a change to Git. GitOps controllers then detect the change and automatically update the live environment to match. This shift brings the principles of software development—such as version control, collaboration, and CI/CD—to operations teams. GitOps is especially valuable in cloud-native environments, where teams work with Kubernetes or similar orchestration tools. GitOps Definition GitOps is a kind of workflow where infrastructure is treated as code (not as a full app or environment), stored in Git. It also reconciles with the actual running environment. This ensures consistency, traceability, and security throughout the deployment lifecycle. How Does GitOps Work? GitOps was created as the main tool to control your apps and infrastructure like the unified entity, which you control from a single Git repository. But how does it work? It’s simple - continuous reconciliation. A GitOps controller constantly checks for differences between the actual state of your infrastructure and the desired state stored in Git. If the live state drifts (due to unnecessary or planned changes) the controller detects the inconsistency and automatically reverts the environment back to the last known perfect state as defined in Git. This is something that makes GitOps a very useful tool. What Are the Main GitOps Tools? GitOps relies on several open-source tools that integrate with your existing CI/CD stack. Here's a quick overview of the most popular options: Argo CD Argo CD is a declarative continuous delivery tool built for Kubernetes. It syncs your manifests from Git to your clusters and helps you visualize deployment status. Flux Flux automates Kubernetes deployments using Git as the source of truth. It's lightweight and integrates well with Helm charts. Helm Helm is a Kubernetes package manager. It makes application definitions simpler and is often used in GitOps to manage complex deployments. Terraform Let’s not forget that Terraform is not GitOps-native, It’s mainly used in GitOps pipelines for managing infrastructure outside Kubernetes, for example DNS. Quick Overview of the GitOps Workflow A typical GitOps workflow involves several tightly integrated steps that form a reliable deployment pipeline. Let’s walk through the process from code commit to live deployment. A developer writes code and pushes it to a Git repository. A CI pipeline builds the code, creates a container image, and pushes it to a container registry. A change is made to a Kubernetes manifest or Helm chart in the Git repository. A GitOps controller (e.g., Argo CD or Flux) detects the change and applies it to the cluster. The cluster state is now aligned with the desired state declared in Git. The separation between CI and CD in this model ensures that your team remains focused on writing and testing code, while deployment and environment reconciliation are fully automated. This reduces risk, accelerates delivery, and improves infrastructure transparency. Benefits of GitOps GitOps offers several advantages for modern DevOps teams: Developer productivity: If you are already familiar with Git, you can easily apply your knowledge. Auditability: You can track and backup every change that was made during the development. Rollback support: You can easily revert changes at any moment if you need to.. Security: You can control access of your repositories all by yourself, without someone crushing into your code. Faster recovery: Everything is "on the air live”, so if you need to backup your file faster. How to Set Up a GitOps Pipeline Here’s a basic example of setting up a GitOps pipeline using Argo CD on a Kubernetes cluster. For Hostman, you can adapt these steps using custom infrastructure. Step 1: Install Argo CD Create a namespace for Argo CD: kubectl create namespace argocd Install Argo CD: kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml Step 2: Access the Argo CD UI Forward the Argo CD API server port: kubectl port-forward svc/argocd-server -n argocd 8080:443 Visit https://localhost:8080 in your browser. Login with the default admin user and password (retrieved from the secret). How to Use GitOps with Kubernetes Now let’s connect your Git repository to Argo CD to start syncing Kubernetes manifests. Step 1: Define Your App Configuration In your Git repo, create a Kubernetes manifest, for example deployment.yaml: apiVersion: apps/v1 kind: Deployment metadata: name: hostman-web spec: replicas: 2 selector: matchLabels: app: hostman-web template: metadata: labels: app: hostman-web spec: containers: - name: web image: hostman/web-app:latest Commit and push the file to Git. Step 2: Create the Argo CD Application Use the Argo CD CLI or web UI to create a new application: argocd app create hostman-web \ --repo https://github.com/your-user/your-repo.git \ --path ./k8s \ --dest-server https://kubernetes.default.svc \ --dest-namespace default Synchronize the app: argocd app sync hostman-web Argo CD will now monitor your repo and update the deployment automatically. Are There Disadvantages of GitOps? While GitOps offers many benefits, there are some challenges to consider: Git conflicts: When multiple teams edit code it can lead to some troubleshooting. Secret management: Git is a more “social” tool, when it comes to storing your secrets, so it’s better to use something else. Complexity at scale: Managing many environments and repositories sometimes becomes chaotic without proper management. Planning ahead and using a modular approach (e.g., mono or multi-repo strategies) can help mitigate these issues. Summary GitOps the bringer of power of Git to your infrastructures. GitOps is seeing your infrastructure as code and automates reconciliation, also let’s not forget that this instrument can enhance visibility, consistency, and deployment speed of your state of art work. FAQ What exactly is GitOps? GitOps is a tool to manage infrastructure and deployments using Git as the single source of truth. Is GitOps only for Kubernetes? While GitOps is a perfect fit for Kubernetes (because of its declarative nature), it’s not limited to it. You can apply GitOps principles to other infrastructure types too. What tools do I need to start with GitOps? Popular GitOps tools include Argo CD, Flux, and Jenkins X. If you're using Hostman, you can easily integrate Git-based workflows with Kubernetes and start automating deployments right away. Do I need to change how I write code? Not really. GitOps works with the Git workflows you're already using — like branches, pull requests, and commits. What changes is how those commits impact your infrastructure: once merged, your environment syncs with your repo automatically.

Criteria for Choosing the Best No-Code Chatbot Builder When searching for a no-code chatbot builder, it's crucial to look at many factors to ensure it will effectively meet your needs. Ease of Use One of the core features of chatbots should be ease of use. This means that even users with no programming experience can easily create and manage chatbots. A no-code platform should be straightforward and accessible for everyone, even if you're not technically skilled.  The platform should offer a variety of ready-to-use templates for typical tasks. It should also have easy options for setting up how the bot responds and what triggers its actions. Customization Customization is a key factor in ensuring that your chatbot matches your brand image and business needs. The ideal no-code platform should allow you to customize in a number of ways: templates and preset functionality. Many platforms offer preset templates for common business needs, such as customer support, lead generation, etc. You can choose the right template and modify it to suit your business needs for a quick start. The no-code chatbot should allow you to customize the appearance design of the chat window, including colors, layout, fonts, button styles, etc., to be consistent with the brand image. In addition to appearance, you can customize the chatbot's conversation flow to ensure that it interacts with users in a personalized and natural way. Integrations A no-code chatbot should support multiple platforms, including websites and social media, e.g., Facebook, WhatsApp, WeChat, etc. This allows you to interact with users on a variety of channels and increase touchpoints. AI Capabilities If your needs include in-depth conversations with your customers, it's critical to choose a platform with robust NLP technology. It can help the chatbot understand and respond to your users' natural language, making conversations smoother and smarter. Pricing Some platforms like Landbot offer free trials (in some cases, even without a credit card). Free trials allow you to test things quickly. Whereas some platforms charge based on usage, number of users, or advanced features. One should opt for platforms with transparent pricing tiers and features. Support Even though no-code chatbot builders are designed to be user-friendly, you’ll likely need assistance from time to time. Excellent customer support and available resources (documentation, tutorials, and community forums) can make your experience much smoother.
