    Apache Kafka

    Despite the disadvantages I list, I really believe that Kafka is the right choice whenever you need a queueing or message broker system. Kafka is way too battle-tested and scales too well to ever not consider it. The only exception is if your use case requires many, many small topics. Also, Kafka doesn't support delay queues out of the box and so you will need to "hack" it through special code on the consumer side.

    Microsoft IIS

    IIS as a web application server is perfectly suited for .net, .net core, asp.net applications. Our core ESB runs on IIS and has hundreds of gigabytes of data moved through it every day spread across millions of transactions. We have other mission critical applications that deliver our results to patients and doctors relying on IIS web application servers. If you stay in the Microsoft development stack, IIS is a top tier, efficient, and reliable web server.

    Pros

    Apache Kafka

    • Apache Kafka is able to handle a large number of I/Os (writes) using 3-4 cheap servers.
    • It scales very well over large workloads and can handle extreme-scale deployments (eg. Linkedin with 300 billion user events each day).
    • The same Kafka setup can be used as a messaging bus, storage system or a log aggregator making it easy to maintain as one system feeding multiple applications.

    Microsoft IIS

    • 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.

    Cons

    Apache Kafka

    • The Kafka Tool is a community-made Java application that looks and feels from the past century.
    • Logging can be confusing. This certainly shows when we have to do troubleshooting.
    • Hybrid scenarios - pub/sub, but there are services in and outside a Kubernetes cluster. Then there are a ~3 options, but only 2 (the harder ones) are production-safe.
    Borislav Traykov | TrustRadius Reviewer

    Microsoft IIS

    • There are some hidden and not very easy to find configurations that would have been better if completely left out, like machine.config. I understand the idea, but sometimes things are easier without trying to make things easy for you.
    • After 15 years of usage I still don't understand why IIS sometimes complains that I already used my *.domain https certificate for another website in the same domain.
    • There are too many versions... IIS should be a product with almost no other functionality than being a web server. It's not necessary to have imcompatible versions.

    Kafka is quickly becoming core product of the organization, indeed it is replacing older messaging systems. No better alternatives found yet

    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.

    Apache Kafka is highly recommended to develop loosely coupled, real-time processing applications. Also, Apache Kafka provides property based configuration. Producer, Consumer and broker contain their own separate property file

    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.

    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.

    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.

    Support for Apache Kafka (if willing to pay) is available from Confluent that includes the same time that created Kafka at Linkedin so they know this software in and out. Moreover, Apache Kafka is well known and best practices documents and deployment scenarios are easily available for download. For example, from eBay, Linkedin, Uber, and NYTimes.

    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.

    Alternatives Considered

    Apache Kafka

    We really needed to get away from using a SQL database to act as a queue for processing records, so a new solution was needed. Kafka is a leading software application initially designed for queuing messages which is essentially what we were looking for. It has a great user community and is used across the industry. We also use and trust several other products from Confluent which helped seal the decision.

    Microsoft IIS

    In my experience, Microsoft IIS was definitely easier to wrap my head around and also to troubleshoot. The GUI was a great visual way to see what "sites" and "app pools" you have, what is running, what is currently up.
    Microsoft IIS also offers the flexibility to have multiple sites and app pools going at the same time and also the versatility to do maintenance on any one without affecting the others.

    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.

    Return on Investment

    Apache Kafka

    • Kafka makes the messaging itself more reliable (as it has the distributed storage by itself and the message doesn't disappear even after it has been consumed).
    • Kafka can support a much higher volume use case, without too much extra pressure on the existed hardware.
    Anonymous | TrustRadius Reviewer

    Microsoft IIS

    • 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.
