IBM i vs. openSUSE Leap vs. Windows Server

IBM i platform is best suited for transaction-based and data warehousing applications. IBM i has proved its high availability and continuity for core banking applications. Since IBM i provides a single server solution for the back end to the front end, it is a simple and efficient system for a business to bring up their application live.

OpenSUSE Leap is well suited for just about any Linux task. Especially I like to use it as Docker base image for my software deployments, because it has a wide variety of software packages available already precompiled and packages are well maintained - vulnerable software versions are patched in reasonable time. OpenSUSE Leap is rpm based system, and it wouldn't install Debian or other systems packages. If your software is not an rpm package then OpenSUSE Leap would not be suitable for your system.

Windows Server and Active Directory is very robust and stable, it has been a staple in every IT environment I have worked in during my career. Junior to Intermediate admins can learn Windows Server easily, the user interfaces make administration tasks very easy as well as the documentation available through a vast amount of resources. There are other Operating Systems available with no GUI which has a smaller attack surface, faster update installation and reboot time. Windows Server does have the ability to remove the desktop experience, however it is not something I have had experience with and I believe most administrators choose not to remove it.

• Needed more CASE tools like RDi on IBM i to be developed.
• The webSphere-related hosting procedure needs to improvised for quick turnaround or setup.
• Just like XML-into, JSON based parser will be helpful to deal with modern data sets.

• Microsoft needs to minimize the update frequency by making the product more secure. It can become very exhausting trying to keep updated if you don't have a dedicated support team. It can become challenging where the business is unable to allow downtime for reboots as part of the update process.
• Prone to security and audit vulnerabilities.
• The operating system needs more CPU and memory resources compared to other options such as Linux.
• Understanding the licensing model can be abit confusing.
• Comes with a standard firewall, but not the most secured one available. Would suggest using a more secured firewall as part of your antivirus software.
• Due to the number of vulnerabilities and the operating system being a target for hackers, anti-virus software is a must.

I've carefully reviewed the servers and services currently running on Windows Server 2012, and given the opportunity would renew them as is going forward. There are two systems I currently have in place, one is a very large Linux implementation for a large ecommerce site, and one is a very large backup solution front ended by FTP servers running Linux. Neither are well suited for Windows, but the overall network infrastructure is and will be Windows Server for the foreseeable future.

Anyone new to IT could easily use the familiar Desktop Experience (GUI) version because we all know how to use Windows, whether a client or server version. Once an IT user is more comfortable with the operating system, they can move on to the Core version, which is the way to go in almost all situations.

some times server hungs and user sessions were busy to connect

need to improve the performance more

Microsoft's support is hugely wide-ranging from articles online to having to contact them directly for the more serious issues. In recent years when I have contacted them directly, I have found the support o be excellent as I have found myself connected to very knowledgeable people in the field in which I needed the support. The online support available is vast and I tend to find most of the time that there is always someone out there who has had the same issue as me in the past and knows something about how to resolve it! This is the advantage of using industry standard and long-established systems such as Windows Server.

it was my senior who trained Windows Server features and i was satisfied

it was recorded session and useful

Make sure that you have detailed processes in place for every server instance you plan to install/upgrade, if possible get the base OS loaded and Windows Updates applied ahead of time, and if using a VM take a snapshot prior to installing each role, as well as along the way.

IBM i platform is single shop solution for multiple business requirements. Its database architecture and security options made it dependable among multiple business domain entities. IBM i is IBM's well-told and well-known system. IBM i is popular in companies in the manufacturing and supply chain business. Thanks to IBM that it kept IBM i (AS400) ever-evolving so far.

openSUSE Leap has wide variety of already precompiled software packages in default repositories. It even has some specific packages in official repositories that are not available in other Linux distribution repositories. It is also very stable and reliable distro - we can predict when new versions will be released and when we should make system upgrades.

They are different experiences, and while the other solutions offer enterprise-grade stability and, in some cases, address Windows server shortcomings (such as patching), they all do the trick, but the other solutions require a deeper technical background/configuration of items at the command line, which some people are not fully comfortable with.

need to reduce a lot

yes i completely agree multi deployment

i like the professional service but need to improve

• Excellent ROI when compared to other technologies that provide similar solutions
• Fortified System Security
• Lower Downtimes

• More effective maintenance means a smaller headcount needed for running the production servers.
• The easiness of deployment means more time we can spend on software development of company-specific applications.
• Great community support and overlap with other Linux systems mean that an answer to nearly any problem is usually one google query away.

• Ability to keep all files in one place and give access to users makes file management easy to control.
• VPN Access to off-site users is a plus.
• Secure access to on-site SQL data from our accounting and estimating data is a plus.
