Do you know the difference between a web server vs. application server? If not, don’t worry! This blog will examine the disparities between the two kinds of servers. A web server delivers fixed content to users, such as HTML pages and pictures. At the same time, an application server is responsible for running applications and performing dynamic content for customers. So, which type of server do you need for your business? Read to know in detail.
What Is a Web Server?
A web server is a device that accumulates websites and serves them to computers linked to the web. Whenever you type a URL, your computer sends a request to the server, which helps you to the page you requested. Web servers are mighty computers designed to handle large amounts of traffic. They typically have multiple processors, immense quantities of memory, and quick storage gadgets. Some of the largest websites in the world receive billions of requests every day, and they would not be able to function without a robust web server infrastructure.
What are the merits of a web server?
1. Increased accessibility: A web server can make your website available to anyone in the world who has access to the internet.
2. Increased security: A web server provides a secure environment for your website and its data.

Most Popular Web Servers
Apache is one of the most popular web servers today for its stability and flexibility. It supports many features, including mod_rewrite for URL rewriting, mod_ssl for secure communications, and mod_gzip for compression.
Microsoft’s IIS web server is a popular choice for Windows-based systems. It helps a broad spectrum of features, including ASP.NET, FastCGI, ISAPI extensions, and URL rewriting.
Nginx is a high-performance web server designed for high-traffic sites. It supports a number of features, including HTTP caching, load balancing, and compression.
Lighttpd is a fast and lightweight web server that can handle large traffic volumes. It supports a number of features, including FastCGI, PHP5-FPM, and URL rewriting.
Tomcat is an open-source Java servlet container that enables Java applications to run in a web server environment. It supports a wide range of features, including load balancing and failover clustering.
What Is an Application Server?
An application server is a type of software that helps manage the resources and workloads of applications. It makes it possible to run multiple applications on one server, improving performance and efficiency.
Additionally, application servers can provide security, scalability, load balancing, and caching to make applications run more smoothly.
What are some of the usefulness of utilizing an application server
1. High Availability
An application server can provide high availability for applications. If one server crashes, another can carry over seamlessly, and the users will not even know a problem.
2. Load Balancing
An application server can also provide load balancing for applications. This means that if the load on one server becomes too high, the traffic can be automatically routed to other servers so that the users experience no interruption in service.
3. Ease of Management
Application servers can be centrally managed, which makes it easy to deploy and manage applications on multiple servers.
Applications running on an application server are typically more secure than those on a web server. This is because application servers usually have more security features enabled by default.
An application server can easily be climbed up or down to satisfy the demands of its hosting applications. This means that the server can handle more or less traffic as needed without making any changes to the applications themselves.
Application servers are typically much faster than web servers when handling requests. This is because they are designed to host applications and not just static content like websites.
If one component of an application server fails, another can take over automatically, so the users experience no interruption in service. This is in contrast to a web server, where a failure of any single component (such as the web server or database) would cause the entire website to go offline.
Application servers can be used to host a wide variety of different types of applications, not just web-based ones. This gives organizations more flexibility in what they can do with their IT infrastructure.
9. Cost Savings
Using an application server rather than deploying individual applications on separate servers often saves cost because it requires fewer servers overall.
What are some of the demerits of using an application server
- An application server can be expensive to license and maintain.
- Application servers can be complex to set up and operate.
- Application servers can be slow to start up.
- They can use a lot of memory and CPU resources.
- They can be challenging to scale up or down.
- Their reliability can be uncertain.
- They can be vulnerable to attack.
Features of Application Servers
Application servers have a number of features that allow them to run applications. These features include:
1. Executing code in a managed environment:
An application server can execute code in a managed environment, which helps to ensure that the code is executed as intended. This helps to prevent errors and improve performance.
2. Support for various programming languages:
Application servers support various programming languages, allowing developers to create applications using their preferred language. This can improve productivity and help with communication between developers and users.
An application server can scale to meet the needs of an application. This confirms that the application can bear the additional load as it grows.
4. Load balancing:
An application server can distribute load across multiple servers, which helps to ensure that the application can handle large amounts of traffic.
5. Fault tolerance:
An application server can tolerate failures of individual servers or components, which helps to keep the application running in case of unexpected issues.
6. Connection pooling:
An application server can maintain a pool of connections to backend systems, which helps to improve performance by reducing the time needed to establish new connections.
7. Efficient resource usage:
An application server can use resources efficiently, which helps to improve performance and minimize costs.
8. Middleware integration:
An application server can integrate with middleware products, which allows the application server to access functionality provided by these products. This can improve efficiency and flexibility.
9. Customizable configuration:
An application server can be configured according to the needs of an organization, which allows it to be tailored for specific applications or use cases.

4. Web servers use a single thread per connection, whereas application servers can use multiple threads per connection.
5. Web servers are typically stateless, whereas application servers may be stateful.
6. Web servers can only serve content stored locally, whereas application servers can fetch content from remote sources.
7. Web servers typically use a simple caching mechanism, whereas application servers typically use a more sophisticated caching tool.
8. Web servers are usually deployed in a standalone configuration, whereas application servers are typically deployed in a clustered configuration.
9. Web server performance is typically limited by CPU and memory capacity, whereas application server performance is typically limited by network capacity.
10. The primary purpose of a web server is to serve static content, whereas the primary purpose of an application server is to serve dynamic content
How can you decide if you need a web server or an application server ?
There is no authoritative explanation to this question. Nevertheless, there are some things to be considered when making the decision.
1. What are the requirements of your project?
2. What is your budget?
3. What is your level of technical expertise?
4. What is your time frame?
- Web servers suffice up static pages and files for users all over the world.
- Application servers, on the other hand, host dynamic content and applications that run inside a web browser.
- Application servers use two protocols: HTTP and HTTPS. This protects user data from being intercepted by third parties.
- Most web hosting providers offer both types of servers: Web and Application. If you require assistance determining which kind of server is suitable for you, contact your hosting provider!
