Amazon's Elastic Load Balancing automatically distributes incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, IP addresses, and Lambda functions. It can handle the varying load of your application traffic in a single Availability Zone or across multiple Availability Zones. Elastic Load Balancing offers three types of load balancers with the vendor states all feature the high availability, automatic scaling, and robust security necessary to make…

Tomcat is an open-source web server supported by Apache.
We use Amazon Elastic Load Balancers to serve mobile applications and websites. It works really well. We have not had any problems until now. Last year we integrated the AWS ELB with the EC2 Auto Scaling and now we have a fully working elastic solution. We increase/decrease EC2s instances based on traffic over our load balancers.

Excellent value for companies wishing to host Java applications in the cloud. Utilizing hosting tools such as load balancers and network and application firewalls, Tomcat can be part of a powerful system to host web applications to thousands of users. There has been consistency in the development and support of Tomcat since its initial release in the late '90s and the best commonalities have been carried forward. If you host Java web applications, Tomcat is as good as any for an application server.

Occasionally we have a huge number of users using our network at once, and Amazon ELB isn't quite fast enough to scale effectively when that occurs. But this doesn't happen very often as our usage is usually quite stable
If we want to add another application to our learning suite, we would have to add another load balancer, which would incur additional cost
The setup was not easy and could really only be handled by one person on our team with the technical background to do so

Using tomcat manager to troubleshoot is not very informative. Error messages are vague, you have to dig into log files for more information about the problems.
Is great for simple web applications, but may not work for heavy development which may require a full J2EE stack, might like JBoss better.
Security in tomcat is not straightforward, as I discovered that you have to understand how to set up realms in tomcat in order to hash passwords, which I was not overly familiar with, which is a big deal when setting up users in the tomcat-users.xml file.

AWS Elastic Load Balancing has this trick. First, you need to know how it works. ELB is not the only piece here. ELB has a very close relation with AWS Target Groups. You create or select a target group every time you create a Load balancer. Target groups allow you to connect the load balancer to EC2 autoscaling groups, Lambda functions, or even a single EC2 instance. While this sounds complex, it becomes easy, once you know his tricks. Thanks to the user interface, managing a ELB is an easy task. The rules editor is really useful, although it will need a bit of improvement to some interface items

Tomcat has a very rich API set which allows us to implement our automation script to trigger the deployment, configure, stop and start Tomcat from the command line. In our projects, we embedded Tomcat in our Eclipse in all of the developer's machines so they could quickly verify their code with little effort, Azure Webapp has strong support for Tomcat so we could move our application to Azure cloud very easy. One drawback is Tomcat UI quite poorly features but we almost do not use it.

Tomcat doesn't have a built-in watchdog that ensures restart upon failure, so you have to provide it externally. A very good solution is java service wrapper. The community edition is able to restart Tomcat upon out of memories exceptions.

Tomcat support to customize memory used and allow us to define the Connection pool and thread pool to increase system performance and availability, Tomcat server itself consume very little memory and almost no footprint. We use Tomcat in our production environment which has up to thousands of concurrent users and it is stable and provides a quick response.

AWS gives you several support plans. On the free plan, you basicaly need to google for help, but the good news is that AWS Elastic Load Balancing works. We has more than 15 load balancers and we never run into a problem that require support. But you mght consider a support plan if you are going to do something more complex or critical

We have not used any other solution out there in the market but our dev-ops team did deep research and AWS provided us the solution we needed to be cost-effective. Also, the decision to keep working with Amazon was strategic. We were already using other AWS features and [Amazon Elastic Load Balancing] integrates great with those.

Eclipse Jetty is the best alternative for Apache Tomcat because which is also an open-source and lightweight servlet container like Tomcat. A major advantage of this over Tomcat is that Jetty server can easily be embedded with the source code of web applications. Since it requires less memory to operate, you may realize that it is very efficient.

Tomcat is cheap and very quick to deploy, so it has benefited much when situation needs applications to be deployed quickly without wasting time on licensing and installations.
Plenty of documentation available so no vendor training is required. Support contract is not needed as well.
