With the right knowledge and tools, you can have your server up and running in no time. In this article, we will guide you through the process step-by-step and make sure you have all the information you need to set up your server successfully. Let’s get started!

What is Apache Tomcat server?

Apache Tomcat server is an open-source software that is used to serve Java-based web applications. It is a popular choice for many developers because it is easy to use, flexible, and has a large user community. Tomcat is designed to run on a variety of operating systems and can be used with many different web servers.

What is AWS?

AWS (Amazon Web Services) is a cloud computing platform that provides a wide range of infrastructure services such as computing power, storage, and databases. AWS is one of the most popular cloud computing platforms in the world, and it is used by many businesses to host their applications and websites.

Why use Apache Tomcat server on AWS?

Using Apache Tomcat server on AWS has many benefits. Firstly, it is a cost-effective solution as you only pay for what you use. Secondly, it is easy to scale as your business grows. Thirdly, it is highly available and can handle a large amount of traffic. Finally, it is secure, with many built-in security features to keep your application safe.

Prerequisites

Before we start setting up our Apache Tomcat server on AWS, there are a few things we need to have:

Prerequisites
Description
AWS account
You need to have an AWS account to use the services.
Java SE Development Kit (JDK)
You need to have JDK installed on your local machine to create and run Java-based web applications.
Apache Tomcat
You need to have Apache Tomcat installed on your local machine to run Java-based web applications.
SSH client
You need to have an SSH client installed on your local machine to connect to your AWS instance.

Step-by-step guide to set up Apache Tomcat server on AWS

Step 1: Launch an Amazon EC2 instance

The first step is to launch an Amazon EC2 instance. This is the virtual machine that will run our Apache Tomcat server.

Step 1.1: Choose an Amazon Machine Image (AMI)

The first thing we need to do is choose an Amazon Machine Image (AMI) to use as our instance. We will use the default Amazon Linux AMI.

Step 1.2: Choose an instance type

The next step is to choose an instance type. We will choose t2.micro, which is the smallest instance type available and should be sufficient for our needs.

Step 1.3: Configure instance details

The next step is to configure the instance details. Here, you can choose the number of instances you want to launch, the VPC you want to use, and other settings. We will use the default settings.

Step 1.4: Add storage

The next step is to add storage to our instance. We will use the default settings.

Step 1.5: Add tags

You can add tags to your instance to help you identify it later. We will use the default settings.

Step 1.6: Configure security group

Finally, we need to configure the security group for our instance. We will create a new security group that allows SSH access from our IP address and HTTP access from anywhere.

Step 2: Install Apache Tomcat on the instance

Now that we have our instance set up, we need to install Apache Tomcat on it.

Step 2.1: Connect to the instance

The first thing we need to do is connect to our instance using SSH. You can use any SSH client to do this, such as PuTTY or Terminal.

Step 2.2: Install Java

The next step is to install Java on our instance. We will install OpenJDK 8 using the following command:

sudo yum install java-1.8.0-openjdk-devel

Step 2.3: Download and install Apache Tomcat

The next step is to download and install Apache Tomcat on our instance. We will download version 9.0.41 using the following command:

wget https://downloads.apache.org/tomcat/tomcat-9/v9.0.41/bin/apache-tomcat-9.0.41.tar.gz

Once the download is complete, we can extract the files using the following command:

tar -xvf apache-tomcat-9.0.41.tar.gz

Step 2.4: Start Apache Tomcat

Now that we have Apache Tomcat installed, we can start the server using the following command:

sudo ./apache-tomcat-9.0.41/bin/startup.sh

You should now be able to access the default Apache Tomcat page by navigating to http://your_instance_public_dns:8080 in your browser.

Step 3: Deploy your web application

The final step is to deploy your web application to the Apache Tomcat server. You can do this by copying your .war file to the webapps directory in the Apache Tomcat installation directory.

Advantages and Disadvantages of setting up Apache Tomcat server on AWS

Advantages

1. Cost-effective

Using AWS is a cost-effective solution as you only pay for what you use. This is especially true if you use services like Amazon EC2, which allows you to pay by the hour for your instances.

2. Scalability

AWS is designed to be highly scalable, so you can easily add or remove capacity as your business needs change. This is particularly useful for applications that experience large fluctuations in traffic.

3. High availability

AWS is designed to be highly available, with many built-in features to ensure that your applications are always up and running. For example, Amazon EC2 instances can be configured to automatically recover from instance failures.

4. Security

AWS has many built-in security features to keep your applications and data safe. For example, Amazon EC2 instances can be configured to use virtual private networks (VPNs) to encrypt traffic.

Disadvantages

1. Complexity

Setting up an Apache Tomcat server on AWS can be a complex process, especially if you are not familiar with AWS. It can take time to learn how to use the various tools and services.

2. Technical expertise

You need to have some technical expertise to set up an Apache Tomcat server on AWS. This includes knowledge of Linux, networking, and security.

3. Cost

While AWS can be cost-effective, it can also be expensive if you do not manage your resources properly. You need to be careful when choosing the services you use and how much you use them.

4. Vendor lock-in

Using AWS can lead to vendor lock-in, where you become reliant on AWS and cannot easily switch to another cloud provider.
