Cloud Infrastructure (IaaS)


We provide users and user groups at MU with an environment to establish and run their virtual servers and virtual environments. This is an Infrastructure as a Service (IaaS) service.

This infrastructure is available to anyone who wants to run any server service, container-based applications, client operating systems in a virtual environment, or to run a comprehensive computing infrastructure. Due to the variety of existing requirements, currently offered solutions are based on two technologies.

 

OpenStack  

The OpenStack cloud environment, which is designed for a wide range of uses, offers maximum flexibility. Users can independently create their virtual servers, networks, and environments. There is an option to control it via a web interface, command line or API. This environment is suitable for most ways of applications. Its main advantage is the wide configuration options available to the user without the need for administrator intervention (self-service). Work in this environment is similar to public cloud services like Amazon EC2, Google Cloud Platform.

The Openstack platform runs in the experimental running with the planned consolidation of cloud services at the end of 2018.

VMware vSphere  

We offer virtualization environment based on VMware vSphere technologies to run virtual servers with high service availability and data security requirements. Here we put the greatest emphasis on the stability of the operating environment. The environment is suitable for example for the running of various infrastructure services that are not specifically designed to run in a cloud environment. Typically, these include mail, webhosting, authentication or file servers. 

We assume that most existing requirements and usage scenarios will suit the OpenStack environment that we recommend as the first choice. To simplify considerations about choosing the right environment, the following tables compare the selected properties of both environments. In case of ambiguity or interest in the consultation please contact vm@ics.muni.cz

Geographically Separated Locations

Thanks to the fact that MU has data centers in several locations, in case of need we can provide geographic separation of the provided services. Currently, we use the data centers in the FI and ÚVT buildings on Botanická Street, in the building on Comenius Square and at the premises of the UKB.

Eligibility and Requirements

The service is provided free of charge to MU employees and workplaces. The service includes the creation of a virtual server in the OpenStack or VMware virtualization environment. We will help you with the choice of the right environment by your requirements and needs.

The service DOES NOT INCLUDE the installation and management of the operating system or server applications. The user must ensure the qualified management of the operating system as well as all running applications. If the user cannot ensure a qualified management, we will help him to find a suitable administrator.
