2. VPH-ShareKUKDM 2015, Kraków, Poland11-13.03.2015 Chosing the solution 2 We have: Analyzed technologies Deploy test site Run tests and benchmarks Verified results …and chosen OpenStack

4. VPH-ShareKUKDM 2015, Kraków, Poland11-13.03.2015 Extensions 4 We have extend the capabilities of OpenStack in following areas: Providing access from the Internet to the VPH-Share services running on instances located in the private LAN without the need to use the public IP for each service to preserve those resources; we achieved this by developing a module which is controlling the standard Linux packet filtering mechanism (netfilter/iptables) to perform Destination Network Address Translation (DNAT) for specific TCP or UDP port(s) of the single IP. Enable replication of images to other private sites based on the OpenStack as well as public services such as Amazon AWS. We have created a set of scripts which properly moves and registers required images to other cloud sites.
