    My favorite way to use Debian OS is to run shared, hosted, network applications for easy segmentation of apps so that when doing work on one you don't have to effect or take down others. I would not use it is for a daily use desktop style OS. For that I would stick to Windows, macOS, or a distribution of Linux that is already geared towards a daily use desktop OS.

    Most of the time, server utilization is reliable and stable during peak times. Truly amazing, this product offers a lot and gets it done in no time without any confusion.It is reliable, too accurate and the performance is top-notch. It seems to be competitive in all virtual energy systems and its connectivity is also good. It's available at a low cost, but it's enough to have as many low-cost, more efficient systems as possible. It's a minor thing, but very rarely, it can cause work interruptions while it can get stuck due to more frequent use such as restless work. These power servers are very efficient and really help when things go wrong. I am using this product to retrieve data much faster.

    Pros
    Open Source
    • The APT package manager is dead simple to use, and the APT repositories contain pretty much every package you can think of. If there's something missing from the standard repositories, there's a good chance a third-party repository can be added to fill the gap.
    • Debian OS releases are often considered, "boring". But that's a good thing! The Debian developers do not make changes for change's sake and this means new releases are very predictable and intended to cause as little drama as possible.
    • Debian is such a widely used and popular Linux distribution, that practically all Linux software vendors officially support it.
    • The Debian community is huge, especially when you consider Ubuntu is derived from it. If you need help with anything, you'll usually find it has been asked before and already has a resolution.

    Cons
    Open Source
    • The installation could include suggested partitioning schemes for those beginning users or those who have their first approach with Debian OS
    • offer encryption of the home partition or the entire hard drive by default
    • an improved visual package manager and if it could be native it would be very well received

    • It would be good if IBM could demonstrate more use cases for Z to potential clients
    • A migration strategy from Open Systems to Z would be helpful
    • Any additional marketing to could explain the benefits of Z/Linux, especially now that RedHat is in the mix.

    Usability
    Open Source
    Debian is one of the most well-thought-out, logical, and intuitive Linux operating systems you can use. Configuration, package management, file system layouts, etc, are all based on many years of usage, and it's very rare to find anything surprising or confusing in everyday usage. Package management and updates are handled by APT in such a way that once configured, you can almost guarantee your system will behave as expected for the lifetime of its service. Top-notch system integration provides all the tools you'd expect from a modern Linux system, with all the stability you demand from a demanding server OS.

    Performance is a major part when you configure your system. IBM has many tools to study your system and suggest the appropriate configuration. With the right contract, you can add processing power dynamically and remove it when no longer needed

    Its has all the needy features that we are looking for plus the support and updates for the OS as well. This means we get all the support and updates in the mean time. Also comparing to others, Debian OS helps us with more security features in built which is also updated over time.

    IBM Z is the best storage solution as it provides the best in class data protection with the cryptographic hardware keys, no loss in data while migration, and a user-friendly interface that makes it easy for develops to understand and has less of a learning curve. This makes it well above the competition.

    If you need more processing power, just add more CPU's or memory. The largest system can have close to 200 CPU's and 40 TB of memory. If that is not enough, you can add more physical computers, and connect them using a sysplex
