    Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n

    > How does one install it?\n

    From what I heard from a former coworker - with great difficulty.\n
    \n
    > What is the difference between a hypervisor/openstack/a container service (podman,docker)?\n
    \n
    A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
    \n
    If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

    \n
    A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n

      Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n

      > What is the difference between a hypervisor/openstack/a container service (podman,docker)?\n
      \n
      A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
      \n
      If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

      Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n
      \n
      > How does one install it?\n
      \n
      From what I heard from a former coworker - with great difficulty.\n
      \n
      > What is the difference between a hypervisor/openstack/a container service (podman,docker)?\n
      \n
      A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
      \n
      If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

      Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n

      \n
      A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
      \n
      If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

      \n
      A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
      \n
      If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
        \n
        If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

        Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n
        \n
        > How does one install it?\n
        \n
        From what I heard from a former coworker - with great difficulty.\n
        \n
        > What is the difference between a hypervisor/openstack/a container service (podman,docker)?\n
        \n
        A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
        \n
        If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

        Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n
        \n
        > How does one install it?\n
        \n
        From what I heard from a former coworker - with great difficulty.\n
        \n
        > What is the difference between a hypervisor/openstack/a container service (podman,docker)?\n
        \n
        A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
        \n
        If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

        Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n
        \n
        > How does one install it?\n
        \n
        From what I heard from a former coworker - with great difficulty.\n
        \n
        > What is the difference between a hypervisor/openstack/a container service (podman,docker)?\n
        \n
        A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
        \n
        If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

        Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n
        \n

        \n
        From what I heard from a former coworker - with great difficulty.\n
        \n
        > What is the difference between a hypervisor/openstack/a container service (podman,docker)?\n
        \n
        A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
        \n
        If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

          Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n

          > What is the difference between a hypervisor/openstack/a container service (podman,docker)?\n
          \n
          A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
          \n
          If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

          Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n

          From what I heard from a former coworker - with great difficulty.\n

          > What is the difference between a hypervisor/openstack/a container service (podman,docker)?\n
          \n
          A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
          \n
          If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

            Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n
            \n
            > How does one install it?\n
            \n
            From what I heard from a former coworker - with great difficulty.\n
            \n
            > What is the difference between a hypervisor/openstack/a container service (podman,docker)?\n
            \n
            A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
            \n
            If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

    There is a lot of complexity and overhead involved in either system. But, the benefits of containerizing and using Kubernetes allow you to standardize a lot of other things with your applications. With Kubernetes, you can standardize your central logging, network monitoring, and much more. And from the developers perspective, they usually don’t even want to deal with VMs. You can run something Docker Desktop or Rancher Desktop on the developer system and that allows them to dev against a real, compliant k8s distro. Kubernetes is also explicitly declarative, something that OpenStack was having trouble being.\n
    \n
    So there are two swim lanes, as I see it: places that need to use VMs because they are using commercial software, which may or may not explicitly support OpenStack, and companies trying to support developers in which case the developers probably want a system that affords a faster path to production while meeting compliance requirements. OpenStack offered a path towards that later case, but Kubernetes came in and created an even better path.\n
    \n
    PS: I didn’t really answer your question”capable” question though. Technically, you can run a kubernetes cluster on top of OpenStack, so by definition Kubernetes offers a subset of the capabilities of OpenStack. But, it encapsulates the best subset for deploying and managing modern applications. Go look at some demos of ArgoCD, for example. Go look at Cilium and Tetragon for network and workload monitoring. Look at what Grafana and Loki are doing for logging/monitoring/instrumentation.\n
    \n
    Because OpenStack lets you deploy nearly anything (and believe me, I was slinging OVAs for anything back in the day) you will never get to that level of standardization of workloads that allows you to do those kind of things. By limiting what the platform can do, you can build really robust tooling around the things you need to do.

            Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n

            \n
            A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
            \n
            If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

    There is a lot of complexity and overhead involved in either system. But, the benefits of containerizing and using Kubernetes allow you to standardize a lot of other things with your applications. With Kubernetes, you can standardize your central logging, network monitoring, and much more. And from the developers perspective, they usually don’t even want to deal with VMs. You can run something Docker Desktop or Rancher Desktop on the developer system and that allows them to dev against a real, compliant k8s distro. Kubernetes is also explicitly declarative, something that OpenStack was having trouble being.\n
    \n
    So there are two swim lanes, as I see it: places that need to use VMs because they are using commercial software, which may or may not explicitly support OpenStack, and companies trying to support developers in which case the developers probably want a system that affords a faster path to production while meeting compliance requirements. OpenStack offered a path towards that later case, but Kubernetes came in and created an even better path.\n
    \n
    PS: I didn’t really answer your question”capable” question though. Technically, you can run a kubernetes cluster on top of OpenStack, so by definition Kubernetes offers a subset of the capabilities of OpenStack. But, it encapsulates the best subset for deploying and managing modern applications. Go look at some demos of ArgoCD, for example. Go look at Cilium and Tetragon for network and workload monitoring. Look at what Grafana and Loki are doing for logging/monitoring/instrumentation.\n
    \n
    Because OpenStack lets you deploy nearly anything (and believe me, I was slinging OVAs for anything back in the day) you will never get to that level of standardization of workloads that allows you to do those kind of things. By limiting what the platform can do, you can build really robust tooling around the things you need to do.

            Openstack is like self-hosting your own cloud provider. My 2 cents is that it’s probably way overkill for personal use. You’d probably be interested in it if you had a lot of physical servers you wanted to present as a single pooled resource for utilization.\n

            \n
            A hypervisor runs virtual machines. A container service runs containers which are like virtual machines that share the host’s kernel (more to it than that but that’s the simplest explanation). Openstack is a large ecosystem of pieces of software that runs the aforementioned components and coordinates it between a horizontally scaling number of physical servers. Here’s a chart showing all the potential components: […wikimedia.org/…/Openstack-map-v20221001.jpg](https://upload.wikimedia.org/wikipedia/commons/a/a5/Openstack-map-v20221001.jpg)\n
            \n
            If you’re asking what the difference between a container service and a hypervisor are then I’d really recommend against pursuing this until you get more experience.

    There is a lot of complexity and overhead involved in either system. But, the benefits of containerizing and using Kubernetes allow you to standardize a lot of other things with your applications. With Kubernetes, you can standardize your central logging, network monitoring, and much more. And from the developers perspective, they usually don’t even want to deal with VMs. You can run something Docker Desktop or Rancher Desktop on the developer system and that allows them to dev against a real, compliant k8s distro. Kubernetes is also explicitly declarative, something that OpenStack was having trouble being.\n
    \n
    So there are two swim lanes, as I see it: places that need to use VMs because they are using commercial software, which may or may not explicitly support OpenStack, and companies trying to support developers in which case the developers probably want a system that affords a faster path to production while meeting compliance requirements. OpenStack offered a path towards that later case, but Kubernetes came in and created an even better path.\n
    \n
    PS: I didn’t really answer your question”capable” question though. Technically, you can run a kubernetes cluster on top of OpenStack, so by definition Kubernetes offers a subset of the capabilities of OpenStack. But, it encapsulates the best subset for deploying and managing modern applications. Go look at some demos of ArgoCD, for example. Go look at Cilium and Tetragon for network and workload monitoring. Look at what Grafana and Loki are doing for logging/monitoring/instrumentation.\n
    \n
    Because OpenStack lets you deploy nearly anything (and believe me, I was slinging OVAs for anything back in the day) you will never get to that level of standardization of workloads that allows you to do those kind of things. By limiting what the platform can do, you can build really robust tooling around the things you need to do.
