Description Software Defined Networking (SDN) is a technology that has introduced an important paradigm shift in the networking world. With the OpenFlow protocol as a main technological enabler, the essential goal is to extend the conventional network configuration approach by introducing the concept of network control and programmability. The advances in the OpenFlow protocol and […]
ICCLab’s MobileCloud Networking solution is supposed to offer private cloud services to end users. MobileCloud is based on OpenStack. Since our OpenStack installation is supposed to be used mainly by end users, it is necessary to provide High Availability.
As mobile end users we all know that we want our IT services to be available everytime and everywhere – 24 hours per day, 7 days per week, 365 days per year. End users normally don’t reflect that this requirement is challenge for system architects, developers and engineers who offer the IT services. Cloud components must be kept under regular maintenance to remain stable and secure. While performing maintenance changes, engineers have to shut down components. At the same time the service should still remain available for the end user. Achieving High Availability in a cloud environment is a very complex and challenging task.
On the 19th February the 2nd Swiss OpenStack User Group Meeting took place. One of the presentations was held on Ceilometer by Toni and Lucas from the ICCLab. They talked about the history, the current and future features, the architecture and the requirements of ceilometer and explained how to use and extend it. You can […]
Description At the heart of the ICCLab is the Management Server, which provides an easy way to stage different setups for different OpenStack instances (productive, experimental, etc.). The Management Server provides a DHCP, PXE and pre-configured processes which allow a bare metal computing unit to be provisioned automatically, using Foreman, and then have preassigned roles installed, […]

Description To be interoperable means to imbue the common abilities of mobility to cloud service instances, to extract all service instance described by a common representation, to share all cloud service instance related data in and out of providers and to allow cloud service instances work together. To bring interoperability, it must be present at […]
