Visual Studio (now in the 2022 edition) is a 64-bit IDE that makes it easier to work with bigger projects and complex workloads, boasting a fluid and responsive experience for users. The IDE features IntelliCode, its automatic code completion tools that understand code context and that can complete up to a whole line at once to drive accurate and confident coding.
IBM Cloud Pak for Applications is clearly suitable for modernizing the WebSphere runtime from the heavy, complex and expensive WAS-ND, and to a lesser extent WAS-base, to the super simple, fast and lightweight WebSphere Liberty runtime. I guarantee, once you start using Liberty you'll never look back. Enough cannot be said about how awesome Transformation Advisor is. The output analysis it produces, along with the migration plan and associated artifacts, considerably simplifies both the decision-making process surrounding modernization and subsequent implementation. Without TA we would've made bad decisions by blindly picking unsuitable apps for moving from WAS to Liberty. Using the results from TA we've excluded multiple WAS apps from our immediate plans to migrate to Liberty, saving time and effort that probably would have resulted in a failed migration. We recently used Transformation Advisor to help us successfully migrate an app from Tomcat to WebSphere Liberty. We needed to make some changes to the Tomcat app, but TA helped highlight these required changes. Without TA I'm not sure we would have succeeded.
It's useful for app development, debugging, and testing. I've been using it for two years and have seen it grow into a fantastic tool. All of the features, NuGet packages, and settings that enable different types of projects are fantastic. It also has a connection to Azure DevOps and Git. It's a fantastic product that's simple to use.
Since Microsoft offers a free Community Edition of the IDE many of our new developers have used it at home or school and are very familiar with the user interface, requiring little training to move up to the paid, enterprise-friendly editions we use.
The online community support for Visual Studio is outstanding, as solid or better than any other commercial or open-source project software.
Microsoft continuously keeps the product up to date and has maintained a history of doing so. They use it internally for their own development so there is little chance it will ever fall out of favor and become unsupported.
While the licensing is considerably simplified than it used to be, I still find it somewhat confusing. For example, WebSphere Liberty Core has an 8:1 VPC ratio. This is clear when dealing with VMs but it is still not clear to me as to whether we get an 8:1 ratio when running on OpenShift or whether we need to purchase additional OpenShift licenses to support running WebSphere Liberty Core in OpenShift.
Not so much related to IBM Cloud Pak for Applications, but while Transformation Advisor is an indispensable tool to help modernize to the WebSphere Liberty runtime, I wish we could run it against WebSphere Liberty itself. The reason being, we are now using TA as a single repository for our configurations. TA also highlights many potential issues when migrating to Liberty; these issues may also be applicable for apps already running in Liberty, we just don't know it yet.
Certain settings and features can sometimes be challenging to locate. The interface isn't always intuitive.
Sometimes there are too many ways to do the same thing. For example, users can quickly add a new workspace in Source Control Explorer when a local path shows as "Not Mapped," but it doesn't indicate that the user might want to check the dropdown list of workspaces. The shortcut of creating a new workspace by clicking on the "Not Mapped" link can lead to developers creating too many workspaces and causing workspace management to become unwieldy. If the shortcut link were removed, the user would be forced to use the Workspace dropdown. While it can add an extra step to the process, workspaces would be managed more easily, and this would enforce consistency. At the very least, there should be a high-level administrative setting to hide the shortcut link.
VS is the best and is required for building Microsoft applications. The quality and usefulness of the product far out-weight the licensing costs associated with it.
The thing I like the most is Visual Studio doesn't suffer from Microsoft's over eager marketing department who feel they need to redesign the UI (think Office and windows) which forces users to loose large amounts of productivity having to learn software that they had previously known.
Between online forums like StackOverflow, online documentation, MSDN forums, and the customer support options, I find it very easy to get support for Visual Studio IDE when I need it. If desired, one can also download the MSDN documentation about the IDE and have it readily available for any support needs.
Comparing IBM Cloud PAK for Applications against alternatives highlights its distinct advantages. Its robust support for hybrid and multi-cloud environments enables unmatched flexibility in application deployment, crucial for businesses seeking to leverage various cloud services. This contrasts with platforms that may limit their focus to a single-cloud approach or offer restricted multi-cloud capabilities.IBM Cloud PAK's seamless integration with AI and data analytics, particularly through IBM Watson, provides powerful tools for developing AI-driven applications. This integration is a key differentiator from competitors that might not offer as comprehensive AI and analytics tools, allowing businesses to easily incorporate advanced technologies into their applications.Furthermore, IBM Cloud PAK for Applications prioritizes ethical AI development and compliance with regulatory standards, aligning with OpenAI’s guidelines. This commitment is essential for organizations that value responsible AI practices and need to adhere to strict privacy and security regulations.The selection of IBM Cloud PAK for Applications was driven by its holistic approach to application development, offering a blend of flexibility, advanced technological integration, and a commitment to ethical standards, making it a superior choice for businesses focused on innovation while adhering to ethical and legal standards.
I personally feel Visual Studio IDE has [a] better interface and [is more] user friendly than other IDEs. It has better code maintainability and intellisense. Its inbuilt team foundation server help coders to check on their code then and go. Better nugget package management, quality testing and gives features to extract TRX file as result of testing which includes all the summary of each test case.
We have been able to migrate apps away from the expensive WAS-ND to the more cost-effective WAS-base without throwing away our WAS-ND licenses. With a 1:4 ratio of WAS-ND to WAS-base we've been able to we've been able to save in excess of 75% on licensing charges for these apps.
By having a license model based on VPC ratios (1:4:8 - WAS-ND:WAS-base:Liberty core) we've been able to move away from using license pooling resulting in over-allocating (i.e. wasting) CPU cores for each license pool, to using consolidated license pools hosting a combination of WAS-ND, WAS-base and Liberty-core. This has allowed us to reduce our licensing costs accordingly.
We've had hundreds of hours saved by the rapid development that Visual Studio provides.
We've lost some time in the Xamarin updates. However, being cross platform, we ultimately saved tons of time not having to create separate apps for iOS and Android.
