		Related Products OpenMetal OpenMetal delivers hosted private cloud and bare metal infrastructure that gives organizations a real alternative to building their own private cloud or committing to a hyperscaler. Our private cloud platform is built on OpenStack and Ceph, giving customers full access to a proven, open source cloud stack without the overhead of managing it themselves. That means more control, more transparency, and a predictable cost structure that public cloud pricing rarely offers at scale. For organizations that need dedicated infrastructure without the operational burden, we offer fully hosted bare metal servers that can run standalone or integrate directly with an OpenMetal private cloud. Deployment is fast, hardware is dedicated, and pricing is fixed so you can focus on the work, not the bill. 40 Ratings Visit Website Freshservice If you're looking for an IT service desk solution that's actually simple, turn to Freshservice.

About OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed and provisioned through APIs with common authentication mechanisms. A dashboard is also available, giving administrators control while empowering their users to provision resources through a web interface. Beyond standard infrastructure-as-a-service functionality, additional components provide orchestration, fault management and service management amongst other services to ensure high availability of user applications. OpenStack is broken up into services to allow you to plug and play components depending on your needs. The openstack map gives you an “at a glance” view of the openstack landscape to see where those services fit and how they can work together.	About flannel is a virtual networking layer designed specifically for containers. OpenShift Container Platform can use it for networking containers instead of the default software-defined networking (SDN) components. This is useful if running OpenShift Container Platform within a cloud provider platform that also relies on SDN, such as OpenStack, and you want to avoid encapsulating packets twice through both platforms. Each flanneld agent provides this infomation to a centralized etcd store so other agents on hosts can route packets to other containers within the flannel network. The following diagram illustrates the architecture and data flow from one container to another using a flannel network.
