Executive SummaryUpdated on Mar 5, 2025

Zend PHP Engine and IIS are competing in the web server technology category. Zend PHP Engine has the upper hand in offering flexibility and developer-centric features, while IIS may be superior for businesses reliant on Microsoft technologies.

Features: Zend PHP Engine provides compatibility and performance enhancements in PHP development, seamless PHP execution, and an extensive library of extensions. IIS stands out with strong integration within Windows Server, native support for multiple languages, and exceptional management capabilities.

Room for Improvement: Zend PHP Engine could refine its centralized support options and improve documentation. IIS could enhance flexibility beyond Windows environments and streamline the complexity in non-Windows server integration. Both technologies could advance user interfaces for better user experience.

Ease of Deployment and Customer Service: IIS benefits from streamlined deployment within the Windows ecosystem, supported by extensive documentation. Zend PHP Engine offers straightforward deployment processes and ample community resources but lacks the centralized support infrastructure provided by Microsoft.

Pricing and ROI: Zend PHP Engine's open-source model results in lower setup costs, promoting a favorable ROI for PHP-focused companies. IIS, while potentially having higher initial costs, offers significant ROI for organizations deeply invested in Windows technologies due to cohesive integration and robust support.

Designs and manages multiple websites while ensuring data backup and disaster recovery

I have experience with AWS, and I am most familiar with the server environment, as we just use the server environment and then use Microsoft products on an AWS environment. I have experience with Windows Server IIS, which I ran on my own on-premise data center. The website was developed and then hosted, and through IIS, we managed the servers. The manageability within the IIS environment is not very difficult. For server management, you need to ensure data backup, data restore, and you have a DR configured to keep the database intact. It was done on-premises, so I had no problem doing that. If you have to go to the cloud, then you should have the storage connected to the IIS server and also have a DR set up for that. I didn't use Microsoft Azure tools, but since it is a Microsoft product, Azure has all the portability, so you don't have to worry about compatibility on the cloud. On a scale of 1-10, I would rate this solution a 10.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"I think that the IIS includes most features that are required by web applications so that they can run smoothly on Windows operating system."

"The product is stable."

"What I like most about this program is the fact that it's built into Windows, and then I also like the interface and the support."

"The solution is simple and very easy to manage compared to Linux."

"The solution is easy to use and connects with Microsoft."

"What I like the most is that it is easy to use."

"IIS fits properly for my business needs, with a lot of possibilities to upgrade the out-of-the-box functionalities, so it is really great."

"The solution integrates well with most Microsoft products."

More IIS pros

"Offers a complete environment to develop PHP applications. It is valuable because it allows you to have a complete stack (PHP, MySQL, Zend Server) enabling the building of a development environment, and to deploy to the production system."

"The cache modules that Zend provides have been able to optimize and accelerate the loading of the pages when there was exponential growth in data volume and quantity of requests. At the same time, the monitoring console allowed us to have a real-time understanding of the resources and to make decisions when they were at the limit."

"Essentially, we get the best performance at very affordable costing."

"Zend Engine gives the flexibility to use external modules to easily expand the functionalities you need for your web project."

"It makes web design easy and quick and gives well finished websites."

"The solution's initial setup process is easy."

"The Zend Framework provides an easy, open source way to produce coding based on the needs of our customers."

More Zend PHP Engine pros

Cons

"The initial setup could be made easier."

"The graphical user interface has room for improvement and can be more user-friendly."

"Presently, some developers do not have technical knowledge of managing IIS, so that needs to be improved in the next release."

"Scalability issues and security concerns need attention from Microsoft."

"IIS needs to improve its security. Its support needs to be faster and clear. The tool's licensing could be cheaper as well."

"The solution's security needs improvement."

"The first level of support is not very good because by the time we speak with them, we are already past that point."

"Products based on Microsoft .NET do not give companies lot of options; either with Server Operating System shipped IIS, or the developer version called IIS Express."

More IIS cons

"Although it offers a complete environment to develop and deploy PHP applications, it has some limitations. For example, when the volume of data increased exponentially, I had problems scaling the system."

"The biggest problem with PHP is you have to write lot of conditions or have to use a framework."

"In terms of improvement, it doesn't support concurrent processing. When we want to process anything on a concurrent basis, we have to divide it into a number of things, like a queue, or we have to run it using Cron jobs. We would like to have the capability to run any thread or process in parallel."

"The main area that Zend needs to improve is to support asynchronous programming tasks, which is facilitated in PHP 7, but not at the same degree as HHVM."

"A general scripting language should be further developed and should be embedded into it."

"Integration of MVC with ORM tools for PHP is okay, but lacking a short list of decent ORM tools for PHP to choose from; there is ample room for improvement in both areas."

"The process of installing and configuring the product is a bit complex and could be improved."

"Integration of MVC with ORM tools for PHP is okay, but lacking a short list of decent ORM tools for PHP to choose from; there is ample room for improvement in both areas."

More Zend PHP Engine cons

Pricing and Cost Advice

"The price of the cloud system is a bit high."

"The solution’s pricing is yearly. The pricing is affordable and not high."

"The cost for IIS is already included in Windows services. We don't have to pay anything extra."

"IIS is expensive."

"The price is good."

"The licensing cost is dependent on the usage."

"Users can get a subscription-based license or a perpetual license for IIS."

"There is no license required for the product as it is role-based. Whenever you go for a Windows platform server, the role has to be installed directly from the server manager. There is no additional cost that has to be paid for that. It is free to use."

More IIS pricing and cost advice

"The solution is open source and you just pay for the server cost."

"No problem with pricing and licensing, as tools are open source. You have to consider training cost, mindset setup cost, as part of the TCO."

"Its pricing depends on the number of users."

"Zend PHP Engine is not an expensive solution."

"The Zend PHP engine is open source technology, so there's no need for us to worry about licensing or other costs."
