Amazon EC2 Auto Scaling vs. Microsoft IIS

[Amazon EC2 Auto Scaling] is simple to set up and pretty self-explanatory. Never had issues around scaling up or down. [Now] we won't need to guess the capacity for our apps or services. The both scaling, up and down is simply perfect, you can actually stop checking every time for resources because this tool takes care of everything

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.

• Dynamic scaling can be configured to respond to a wide variety of metrics and alerts
• Predictive scaling allows one to get ahead of high traffic events rather than simply reacting to them
• Health checks are configurable based on the needs of your application and architecture

• 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.

• Sometimes, Auto scaling takes time to spin up your instances if your traffic is so high in short span of time.
• And, Auto scaling can be more efficient if we have only Load balancer in our architecture.
• It has some limitations on setting up the Auto scaling infra.

• 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.

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 is good since we already know how AWS works. For those that are new it might be a little bit confusing at the beginning but they are improving it at a fast pace. Even though AWS keeps changing the user interface constantly, it is still powerful, understandable and easy to use. For technical people, they still offer the CLI.

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.

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.

The platform works as is. The help and tutorials on the help page can help you to setup the entire platform without problems, and also provides help on a huge variety of problems. Amazon also provides support plans. We have the basic support plan, but Amazon offers three support tiers, and we know that it works perfect.

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 operating system, CPU, RAM, and storage may be constructed in any configuration and readily altered after the build. The most important factor is the "sense of security."Problems may arise once every several years, but there is a significant difference when discussing how to cope with hardware problems in the local age.

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.

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.

• We will devote more time to development than server administration, but we will require additional time if you migrate from another ecosystem.
• Fault detection and reporting are automated in the old server, and bandwidth is fixed per month, but everything is manageable automatically. We only pay for the resources we use.
• After some months, we met our return on investment (ROI).

• 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.
