Apache Tomcat vs. VMware vSAN

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.

The product is a must for enterprise & SMB segments as this gives a good value for money and the licensing policy is very well defined and cost effective for the feature set it provides. This is very well suited for organization which have multiple brand storage systems and would like to consolidate them all together, thus providing a huge storage capacity for the organizations data growth. The product becomes less appropriate in organization where they have single storage platform as the service provider would have the ability to consilidate all the storage systems. Hence this products may be under utilized.

• 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.

• VMware runs VSAN certification programs to make sure the OEM sells validated nodes. It helps customers to select appropriate certified ready nodes like Lenovo ThinkAgile VX which comes factory configured and easy to set up.
• Hyperconverged solutions reduce real estate space and networking costs when compare with shared storage. The host overhead also less.
• Supports All-Flash (SATA and NVMe SSDs) and Hybrid vSAN with HDD and SSD. So customers can choose cost-effective solutions appropriate to their workloads.
• Supports different storage policies, RAID and duplication, and compression features and it makes a complete storage solution.

• 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.

• We were a fairly early adopter of VMware vSAN and as such experienced several growing pains.
• We experienced a few bugs that took a few software versions upgrades to go mostly away.
• The biggest issue we had overall was with host drivers. Even with vSAN ready node compatible hosts, you have to be very careful that the drivers for NIC and RAID controllers are right.

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.

Deploying and configuring VSAN is a relatively simple process for people that are already used to working in virtual environments, primarily for those that are familiar with vSphere. The compatibility of those two products is amazing. You shouldn't really encounter any issues and if you do, you surely did something wrong.

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.

Support is (as always forVMware) top notch and easy to work with. The majority of computer companies are outsourcing their tech staff, and it seems they do as well. But their guys know the product well and are quick to respond to your ticket (if the severity is right!).

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.

Our VMware solution is built in-house for the organization's private application, we don't want to put our data on cloud premises. Also, vSAN is a cost-effective solution for our environment. We have done the POC with both products to understand the Flexibility, Management, and cost. After the successful POC, we have chosen the VMware vSAN.

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.

• we have realized savings in the licensing compared to traditional storage (over $500,000 over the last 5 years)
• we have realized ROI through efficiencies in our staff of approx $1MM (over the last 5 years)
• also, positive impact on the time to value/speed of implementation allowed us to realize business objectives (Over $1MM of ROI)
