Scalability Issues

Sentiment score

6.6

IBM DataPower Gateway is scalable and ideal for large enterprises but may be costly and less flexible for smaller firms.

Sentiment score

7.1

IIS scalability is mixed; effective with clustering and load balancing, but larger scales may need extra infrastructure or cloud migration.

Once you install the product, we can't scale the resources on the IBM DataPower Gateway.

Cloud solutions may have better scalability options compared to IIS.

Juan Pablo Lauterio

Chief Technology Officer at EVtech

It depends on the server environment and the presence of a UPS for power backup.

Ibrahim Sherif

IT System Administrator at Bouri

I would rate the scalability of IIS as a six, mainly due to integration issues since it cannot integrate with other environments.

Room For Improvement

IBM DataPower Gateway needs simplified scripting, user-friendly design, flexible pricing, enhanced integration, and improved maintenance and customization.

IIS struggles with compatibility, security, usability, and integration issues, inconsistent performance, costly licensing, and limited technical support.

Whenever I am writing code, it should give recommendations automatically by incorporating AI so I can write the code in a few minutes or seconds.

Naresh Jatangi

Middleware Administrator at Pronteff IT Solutions

However, from the development perspective, it has limitations because it only supports the XSLT language.

AkshaySawant

Manager at CSB Bank Ltd

My experience with the pricing of this product is that pricing is too high and should be reduced.

reviewer1344021

It's influenced by the server's service performance.

Ibrahim Sherif

IT System Administrator at Bouri

If I compare IIS to other web servers such as Apache, which can be deployed in other environments like Linux, I find IIS is mostly used for simple things.

reviewer1256511

Setup Cost

IBM DataPower Gateway is costly, especially for smaller firms, yet valued by enterprises; more flexible pricing would broaden accessibility.

Enterprise users find IIS cost-effective within Windows but some see high licensing fees compared to Linux alternatives.

I think it costs around 5 Crore in Indian Rupees.

AkshaySawant

Manager at CSB Bank Ltd

Valuable Features

IBM DataPower Gateway excels in security, integration, performance, and API management, offering robust features like SSL management and load balancing.

IIS offers seamless Microsoft integration, robust management, enhanced security, resource efficiency, user-friendly interface, and robust web hosting support.

No other Gateway offers this as part of the integration offering.

Naresh Jatangi

Middleware Administrator at Pronteff IT Solutions

As per the development perspective, there are some limitations with IBM DataPower Gateway because it only supports XML and XSLT language, but it does not support the Java language.

AkshaySawant

Manager at CSB Bank Ltd

IBM DataPower Gateway's multi-protocol transformation is important for my integration needs because all the API traffic is coming from this API data gateway.

Security features excel but development limitations emerge

We are using the IBM DataPower Gateway for security purposes. As per the development perspective, there are some limitations with IBM DataPower Gateway because it only supports XML and XSLT language, but it does not support the Java language. This is the only limitation of the IBM DataPower Gateway. For the authentication and authorization purpose, we can use the IBM DataPower Gateway. It's a very good product. We are mostly using the IBM DataPower Gateway for security purposes and load balancing purposes. If we are handling the load for a particular server, then we can use the IBM DataPower Gateway. The IBM DataPower Gateway is mostly used for security purposes. If we have some APIs and we are using some security for those APIs, then we can use it. It can also be used as a load balancer. It's also used for certificate management, user management purposes, authentication, and authorization. For routing, the IBM DataPower Gateway has multiple URL-based routing and content-based routing capabilities. If we have multiple URLs, then we can use an XML script. Using the XSLT language, we can configure multiple URLs and implement URL-based routing. Content-based routing means if we have multiple requests, we can route the request to a particular URL. For this, we need to use the XSLT language only. We can't use XML, Java, or other scripting languages. With IBM DataPower Gateway, we are using all the APIs. All APIs have been configured on the gateway. We have configured the particular TLS profile and some TLS client profiles as well. Using that TLS profile, we have configured the APIs and authentication. We have configured some tokens also, including JWT tokens and different types of auth tokens. There is also a rate limiting feature which we use for handling API loads.

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.
