Apache Tomcat vs. AWS Auto Scaling

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.

It is well suited for scaling up our cloud virtual machines to handle the increase or decrease in workload. It really helps us to satisfy the demand because it doesn't take lot of time to spin up new machines. If there is unpredictability in the demand it is very useful. But it is a over kill if demand is consistent.

• Fast to start up, which is useful when we need to just check that our changes are working correctly.
• Free, which allows us to not be involved with the finance/legal team about using it.
• Bundled with Spring Boot, which makes it even more convenient for our testing.

• Set policies to add more instances when CPU utilization exceeds.
• Prevents downtime, as we don't need to stop the servers.
• Auto Scaling group can be setup for different types of apps.

• 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.

• Update code and configuration when the number of servers is always changing
• How will user-uploaded content make it to new servers

We have a huge knowledge of the product within our company and we're satisfied with the performance.

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.

We use AWS auto scaling for scaling up our cloud virtual machines to handle the increase or decrease in workload. It really helps us to satisfy the demand because it doesn't take lot of time to spin up new machines. I gave the rating 10 because it really does help you to handle the sudden spike in number of requests.

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.

Well, in actuality, I have never needed support for Apache Tomcat since it is configured and ready-to-go with no configuration needed on my end.

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.

Used for the below reasons:

• Easy to implement and use
• Pay per use, cost savings
• Automate and build scaling plans
• Automate performance and workload

It's very easy to add instances to an existing deployment and, using apache with mod proxy balancer, to scale up the serving farm

• 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.

• optimized the cost effectiveness
• save lot of money which help the organization to use it in effective areas
• Not applicable for all use cases.It is specific use cases and business problems
