Apache HTTP Server vs. Apache Tomcat vs. Microsoft IIS

As I mentioned earlier, the Apache HTTP Server has a small disadvantage compared to the competition (NGINX) in terms of performance. If you run websites that really have a lot of visitors, NGINX might be the better alternative.

On the other hand, the Apache HTTP Server is open source and free. Further functionalities can be activated via modules. The documentation is really excellent.

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.

Publishing applications or websites is easy with Microsoft IIS. You don't need external software or complicated tutorials involving command lines and editing configuration files. On other hand, sometimes the troubleshooter needs a high knowledge of Windows Server, Registry, and tools to debug the application. If you need to host non-Microsoft technology as PHP pages or have a low budget, I recommend IIS equivalent software as Apache.

• Street Cred: Apache Web Server is the Founder for all of Apache Foundation's other projects. Without the Web Server, Apache Foundation would look very different. That being said, they have done a good job of maintaining the code base, and keeping a lot of what makes Apache so special
• Stability: Apache is rock-solid. While no software is perfect, Apache can parse your web sources quickly and cleanly.
• Flexibility: Need to startup your own Webpage? Done. Wordpress? Yup. REST Endpoint? Check. Honeypot? Absolutely.

• 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.

• A big advantage that we use all the time is reviewing the logs that automatically get generated in IIS. It has helped us troubleshoot various problems in our applications over the years.
• IIS integrates really well with Visual Studio and TFS. We are able to quickly deploy new applications and changes to applications when requested by the business.
• IIS has proven that it is easy to configure and maintain with minimal effort.

• The default configurations which comes with Apache server needs to get optimized for performance and security with every new installation as these defaults are not recommended to push on the production environment directly.
• Security options and advanced configurations are not easy to set up and require an additional level of expertise.
• Admin frontend GUI could be improved to a great extent to match with other enterprise tools available to serve similar requirements.

• 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.

• Angular/node apps don't run on IIS, or at least we never figured out how. Rather we ended up using nginx.
• There are still occasional memory leaks - check your recycle settings!
• If you have very heavy usage for web APIs, IIS requires regular restarts for reasons unknown.

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

We have no intention to replace all applications running on top of the IIS platform. Not all applications support other platforms and not all support staff are skilled in Linux/Apache platform support. Whereas IIS may not be the best performing or most secure web platform available, for the aforementioned reasons, it is impossible not to continue use of this product.

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.

As I've mentioned earlier, Microsoft IIS is very simple and easy to use. The user interface is a little bit overloaded with a huge number of different options, but once you have a little clue of what you are doing and what you need - no issues at all.

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.

ARR (application request routing) in Microsoft IIS Server enables the web-admins to increase the web app reliability and availability through the rule based routing and load balancing of HTTP requests which in turn provides highly available server. IIS 7.0 Manager also provides kernel as well as user mode caching for faster performance and in case if the server fails, the IIS server has good amount of details logged in its log files which help understand and debug the cause quickly. Load balancing facilitates IIS server to fight against availability issues.

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.

In my experience, I have never had significant issues with IIS performance. Sometimes I've experienced issues with loading time, but it is mostly related to the web site code. However Amazon, Microsoft and Google providing free cloud services with very limited resources, and in that scenario, "heavy" websites on IIS could be the issue. In other situations - performance is good.

I give this rating because there is so much Apache documentation and information on the web that you can literally do anything. This has to do with the fact that there is a huge Open Source community that is beyond mature and perhaps one of the most helpful to be found. The only thing that should hold anyone back from anything is that they can not read. RTFM, my friend. And I must say that the manual is excellent.

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.

As mentioned earlier there is so much documentation or guides or stack overflow questions out there that someone will have faced the same or very similar scenario to what you are going through that you will almost certainly find a solution to what you are after.

I has a lot more features, except that IIS is more integrated in a Windows environment. But now with .net core also possible from Apache it would work anywhere really. Only in a full Windows environment where full integration is needed I would chose to go for IIS. Otherwise Apache it is.

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.

Apache is java. Java is unnecessary complex. No developer wants to invest in learning all the hundreds of text based configuration files to get something done. Also, apache gives you the most evil and un-usable user interface possible. [Microsoft] IIS makes [life] after development easy, which is already complex enough to be bothered by something as mundane as exposing your work over the internet.

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

Microsoft IIS Server is scalable if the underlying server configuration is done correctly. Use x64 edition v/s 32bit and using 32bit mode application pools are some of the tweaks to be done to make the IIS server scalable. There are too many small configurations need to be carried out in order to make a highly scalable IIS server hence not giving full score in this area.

• Works as intended, so it's less to worry about.
• Works great on elastic environments (like EC2).
• As an Open Source project, you can get support for almost any problem you can have.
• Configuration files, while powerful, can be tricky to dominate for some.

• 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.

• Allowing us to internally host our monitoring websites allows quick access to data that can be quite hidden, saving developer time.
• It was inexpensive compared to more bulky solutions saving upfront cost.
• It’s easy to install and enable allowing more developer savings.
