Microsoft IIS vs. Oracle WebLogic Server

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.

I see Oracle WebLogic Application Server being appropriate when an application needs several different data sources and messaging providers configured and accessible, with a configured level of control of resources (connection pools) and timeouts. It is also advisable to create distributed resources that you can configure as always active to provide more processing power, or as failover for situations of availability in case of disaster recovery, for example. An application where the number of required resources configured is very small and almost non-changeable, and no scalability is required, some other options exist in the market with less cost.

• 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.

• I love that the weblogic dashboard allows you to manage applications and see the status of each application.
• Oracle WebLogic Application Server simplifies usage periods in the development and production of business applications.
• Oracle WebLogic Server allows me to define various aspects of data source entry, including creating a specific multiple connection to facilitate data entry.
• Performance and administration are highlighted in weblogic.

• For some web applications, it takes additional time to configure IIS to make a website work.
• IIS logging - it is not the strongest side of the product.
• Compared to Apache or Nginx, IIS uses way more system resources.
• Even with regular patches, IIS has many vulnerabilities.

• The Admin UI should be further simplified, the UI design was not too user-friendly— too many options and clicks required, difficult for the new beginners to figure out what they are looking for.
• The admin server becomes the single failure point, although Oracle suggested some workarounds by setting VIP and VHost, it was not quite easy and straight forward.
• Domain replication is hard, requiring a lot of knowledge and scripts efforts.
• Admin will hang if the node manager communication encounters some issues for one or some nodes in the domain/cluster.
• Not able to kill/terminate the stuck thread, the only way is to restart the managed server (JVM)
• License cost is too high, for small businesses.

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.

In general, Microsoft IIS is an alright product. It comes natively with Windows Server. It has good enough GUI to set things up & tweak things around. Once properly setup, it runs stably enough. And with enough Powershell magic, having a CI/CD pipeline to automatically deploy a new version of the application is doable.

Oracle WebLogic Server has so many features that sometimes it's hard to find the right place to setup things, I think the dated user interface does not help with that either. This has a direct impact when deciding to use it as your application server, you'd need to have the right people and invest the time needed to master it. If you're application justifies it then it will definitely be a great choice in the long run.

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.

Oracle WebLogic Application Server is great at security, performance and features.

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.

The Oracle support is not great sometimes. They take a long time and need a lot of data over and over to resolve issues.

On Windows, Microsoft IIS is easier to implement and maintain than Apache web service. Normally if you need to host PHP or other apache native content on a Windows server, it's recommended to use WAMP or equivalent software to simplify the installation, administration, and configuration of resources. However, you can use Microsoft IIS and other web services on the same server, taking care to keep separate folders and port usage for each system.

I wasn't involved in selecting the server we were using but in our team we've made some efforts to improve the local deployment process by trying some other Applicational servers too. Apache Tomcat was a more lightweight solution for sure, and it coped well with our applications needs, configuration and performance wise. Despite that, since we didn't got clearance to change that into our local servers, we kept using Weblogic to guarantee compliance between the testing environments and production.

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.

• Speed of development. You don't need to be an expert to expose your website through some DNS
• Robust, there has never been any downtime because of IIS itself.
• The ease of use can have (and has had) some negative impact because it's too easy to implement something, and then forget. When a server is taken down, those unthoughtful implementations come to light the hard way.

• It made it easy to handle over a 100 of deployments across multiple nodes every quarter.
• It was easy to scale up our application to 36 nodes as the volume of transactions increased over the years.
• Helped us achieve 99.999 availability for our users.
