Docker is an open-source containerization platform. It enables developers to package applications into containers—standardized executable components combining application source code with the operating system (OS) libraries and dependencies required to run that code in any environment. Containers simplify the delivery of distributed applications and have become increasingly popular as organizations shift to cloud-native development and hybrid multi-cloud environments.

Developers can create containers without Docker, but the platform makes it easier, simpler, and safer to build, deploy and manage containers. Docker is essentially a toolkit that enables developers to build, deploy, run, update, and stop containers using simple commands and work-saving automation through a single API.

It used to be that when you wanted to run a web application, you bought a server, installed Linux, set up a LAMP stack, and ran the app. If your app got popular, you practiced good load balancing by setting up a second server to ensure the application wouldn't crash from too much traffic.

One of the great things about open source is that you have a choice in what technology you use to accomplish a task. The Docker engine can be useful for lone developers who need a lightweight, clean environment for testing, but without a need for complex orchestration. If Docker is available on your system and everyone around you is familiar with the Docker toolchain, then Docker Community Edition is a great way to get started with containers.

     Docker enhanced the native Linux containerization capabilities with technologies that enable:

While LXC containers often reference machine-specific configurations, Docker containers run without modification across any desktop, data center, and cloud environment.

With LXC, multiple processes can be combined within a single container. With Docker containers, only one process can run in each container. This makes it possible to build an application that can continue running while one of its parts is taken down for an update or repair.

Docker can automatically build a container based on application source code.

Docker can track versions of a container image, roll back to previous versions, and trace who built a version and how. It can even upload only the deltas between an existing version and a new one.

Existing containers can be used as base images—essentially like templates for building new containers.

Developers can access an open-source registry containing thousands of user-contributed containers.

   Image: Image is an executable package that has everything that is needed for running applications, which 
   includes a configuration file, environment variables, runtime, and libraries.

   Docker File: Every Docker container starts with a simple text file containing instructions for how to build the 
   Docker container image. Docker File automates the process of Docker image creation. It’s essentially a list of 
   command-line interface (CLI) instructions that Docker Engine will run to assemble the image.

   Build: Creates an image snapshot from the Docker file.

   Docker Daemon: Docker daemon is a service running on your operating systems, such as Microsoft Windows 
   or Apple macOS, or iOS. This service creates and manages your Docker images for you using the commands 
   from the client, acting as the control center of your Docker implementation.

   Docker Registry: A Docker registry is a scalable open-source storage and distribution system for docker 
   images. The registry enables you to track image versions in repositories, using tagging for identification. This 
   is accomplished using git, a version control tool.

   Docker Engine: The system that allows you to create and run Docker containers.

   Docker Container: A lightweight software package/unit created from a specific image version.

   Docker Hub: Image repository where we can find different types of images.

Linux containers have facilitated a massive shift in high-availability computing. There are many toolsets out there to help you run services, or even your entire operating system, in containers. The Open Container Initiative (OCI) is an industry standards organization that encourages innovation while avoiding the danger of vendor lock-in. Thanks to the OCI, you have a choice when choosing a container toolchain, including Docker, CRI-O, Pod man, LXC, and others.

The purpose of this blog post is to discuss why it is so popular, why it should be used, what tools and terms it offers, and what alternatives to it exist.

Overview of Docker: how to use it and what its tools can do

What is Vercel?
Vercel is a cloud platform primarily designed for frontend frameworks and static websites, most notably Next.js (which was developed by the same team). Vercel provides a seamless developer experience, focusing on simplicity, speed, and performance. Deploying your application typically involves a few clicks or a single CLI command. Under the hood, Vercel uses serverless functions and edge networks to deliver fast, globally distributed content.

Optimized for Frontend: Tight integration with Next.js and other popular frontend frameworks like React, Vue, and Svelte.

Serverless Functions: Easy to deploy backend functionality without managing servers.

Automatic Scaling: The platform automatically scales up or down based on traffic.

Simple CI/CD: Connect to your GitHub or GitLab repo, and Vercel automatically deploys and previews your changes.

Built-In Edge Network: Distributes your content globally for lower latency.

Extremely developer-friendly interface and workflows.

Minimal configuration needed to get started, great for small teams.

Free tier for hobby projects and small-scale applications.

Built-in CDN and caching capabilities improve performance.

Primarily suited for frontend and serverless backends. For complex infrastructure needs, it may not be as flexible.

Limited in-depth customization compared to managing your own servers or more comprehensive cloud solutions.

Higher costs can accumulate if you exceed free or basic tiers and need more advanced functionalities.

What is AWS?
Amazon Web Services (AWS) is a comprehensive cloud computing platform that offers hundreds of services—from computing power and database storage to machine learning and IoT (Internet of Things). AWS’s unmatched scale and breadth of services make it a go-to choice for large enterprises as well as businesses with more complex needs.

Compute: Amazon EC2 (virtual servers), AWS Lambda (serverless), AWS Fargate (containers), etc.

Storage: Amazon S3 (object storage), Amazon EBS (block storage).

Databases: Amazon RDS (relational), DynamoDB (NoSQL), and more.

Networking: Amazon CloudFront (CDN), Amazon Route 53 (DNS), VPCs (Virtual Private Clouds).

Advanced Services: AWS AI/ML, Data Lakes, Analytics, IoT, etc.

Unparalleled flexibility: You can build almost any type of application at any scale.

Massive ecosystem of tools, integrations, and third-party services.

Highly scalable—proven track record powering some of the largest global apps.

Robust documentation, enterprise-level security, compliance, and global availability.

The sheer number of services can be overwhelming, especially for new startups.

Complex pricing structure. It can be difficult to anticipate monthly costs if you don’t monitor usage carefully.

Requires management and configuration that can be time-consuming for small teams.

The learning curve can be steep, potentially requiring specialized DevOps expertise.

When deciding between Vercel and AWS, consider the core needs of your startup.

Speed to MarketVercel excels at rapid deployment. If your startup is primarily building a web app (especially with Next.js or another modern JS framework), Vercel can simplify launch and iteration.
AWS can still be quick for serverless or simple hosting (e.g., using S3 + CloudFront or Amplify), but configuration can take longer, especially if you need multi-service orchestration.


Scalability NeedsVercel scales serverless functions automatically, suitable for many early-stage applications. However, if you anticipate needing robust database solutions, specialized services (like AI/ML), or complex microservices, you might eventually outgrow some of Vercel’s capabilities.
AWS is built to handle massive scale; you can start small and scale to millions of users. If your startup is in a domain where you need advanced or specialized services, AWS’s broad portfolio becomes a major advantage.


Team Size & ExpertiseVercel is beginner-friendly, requiring minimal DevOps or infrastructure knowledge. This is a boon for teams with fewer engineers or who want to focus purely on product features.
AWS often requires more in-house expertise or at least a willingness to learn about networking, security groups, IAM (Identity and Access Management), etc. This can be worthwhile if you need the power and flexibility AWS offers—but it can also slow you down if your team is small and trying to do it all.


Budget ConstraintsVercel offers a generous free tier for personal or small-scale projects. Costs typically start to climb if you have high traffic or need advanced team collaboration features.
AWS also has a free tier for some of its services for new accounts, but you can quickly exceed it if you’re not careful. Monitoring usage is crucial to avoid surprises.


Long-Term RoadmapIf your roadmap primarily revolves around building user-facing frontends and lightweight serverless functions, Vercel is likely sufficient for quite a while.
If your roadmap includes diverse needs—like big data analytics, AI-driven features, streaming, or IoT—AWS might be a better long-term choice, allowing your infrastructure to grow with your product.


Vercel:Free tier that covers personal projects and basic usage.
Pro and Enterprise plans for higher traffic and collaboration.
Straightforward pricing for bandwidth and serverless function invocations.


AWS:Has a 12-month free tier for new accounts, but it’s easy to accidentally exceed it.
Many pricing models: on-demand, reserved instances, spot instances, usage-based for services like S3, Lambda, etc.
Potential for high cost efficiency at scale if you optimize carefully—but requires ongoing cost analysis.


Your primary application is a web frontend (especially Next.js) and you want quick, easy deployments.

You prefer to avoid deep DevOps configuration and want a developer-centric platform.

Your backend needs can be addressed with serverless functions or third-party APIs.

You’re in the MVP or early growth stage, optimizing for speed to market and simplicity.

You need a wide range of services (databases, AI, analytics, etc.) and want to keep them all under one provider.

Scalability, resilience, and global availability are top priorities from day one.

Your startup has the resources or expertise to handle infrastructure management or is willing to invest in DevOps.

You require specialized compliance, security frameworks, or enterprise-grade solutions.

Use Vercel for frontend hosting and serverless functions (focusing on an outstanding developer experience and quick iteration).

Employ AWS for more advanced backend services, like a managed database (Amazon RDS), data processing (Lambda, Kinesis, etc.), or machine learning workloads (SageMaker).

This way, your startup can leverage the best of both worlds: a streamlined frontend deployment pipeline on Vercel and the extensive, customizable backend ecosystem of AWS.

Choosing between Vercel and AWS ultimately comes down to your startup’s immediate goals, team expertise, and long-term vision. If you need a fast, easy-to-use platform to get a product to market quickly—particularly for modern web applications—Vercel is tough to beat. On the other hand, if you anticipate needing a wide array of infrastructure services or more granular control as you grow, AWS is often the natural choice.

In many cases, startups begin with Vercel for simplicity and low overhead, and then transition or integrate with AWS services as their product matures. Whatever path you choose, keep your growth trajectory in mind and ensure that the platform you pick can evolve alongside your business. With careful planning, both Vercel and AWS can be powerful allies in turning your startup vision into reality.

Vercel is a developer-friendly platform for fast web deployments and serverless functions, while AWS offers a massive range of services and scalability but can be complex for startups.
