    LTM's scope of action goes beyond load balancing. Tools for control, governance, and application enhancement, as well as APIs like iRULE, are very important for day-to-day operations. Furthermore, the F5 BIG-IP WAF offers exceptional security. Advanced firewall and routing functionalities are helpful in more complex environments. O LTM possui um escopo de atuacao que vai alem do balanceamento. Ferramentas para controle, governanca e aprimoramento de aplicacoes e API como iRULE sao muito iportantes para o dia a dia a operacao. Alem disso o WAF do F5 BIG-IP tem uma qualidade de seguranca exceptional. As funcionalidades avancadas de firewall e roteamento ajudam em ambientes mais complexos.

    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.

    Pros
    F5
    • My company is kind of like it's a safe thing if you log in and you provide another second login to get the code to log in, confirm that it's a correct that you are logged into the account and it just provides more for the company

    • 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
    F5
    • I think a couple of challenges. One, I mean the cost, it's not an inexpensive product, but I think it's probably parity with value, maybe a little on the pricey side of things.
    • As far as features and what we'd like to see more cloud native type experiences like where NGINX and F5 kind of come together, we're moving more of the cloud just like everybody else, and it's a little clunky right now.

    • 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.

    Stability of product and easy way to have account manager contact. F5 support team is also always available to help with major issues. Last year during the major OS upgrade F5 team and F5 leadership always shared clear information and F5 team was dedicated to help us to have it closed in record time

    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.

    Usability
    F5
    It is a good product to use but right now it is lacking the automation of certificates, management of iRules and automation of certain configuration. Also creating an APM policy from scratch with many APM agents take a long time due to slow load times of the GUI and the need to create everything from scratch every time. It's tough to reuse the configuration.

    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.

    I've supported F5 for three different companies. Our F5 support has been very consistent, regardless who the customer is. F5 technicians are very experienced and provide good support, even when issues are more related to knowledge than they are with the ability of the product to do what you need it to do.

    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.

    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.

    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.

    • It was inexpensive compared to more bulky solutions saving upfront cost.
    • It’s easy to install and enable allowing more developer savings.
