SIM-Cloud 2.0: something new and useful

SIM-Cloud IaaS v.2.0

SIM-Networks is constantly working on functionality enhancement and perfection of the SIM-Cloud hardware and software. We have recently completed another iteration of our work, which resulted in the SIM-Cloud IaaS gaining a number of essential updates that provide more capabilities to our users.

1. Platform

The SIM-Cloud IaaS is based on OpenStack platform. As a part of a complex update for our cloud, we have switched from OpenStack Mitaka to the Newton release. The developers working on Newton have fixed a number of bugs and have significantly improved the functionality and the performance of some services.

2. IaaS SIM-Cloud computational nodes


  • Ubuntu Server OS was updated from 14.04 LTS to Ubuntu Server 16.04 LTS on all nodes. More up-to-date Linux/Qemu/Openvswitch cores facilitate greater performance and stability.
  • A new version of GNU/Linux OS has been delivered. The update includes the new version of Linux 4.4 core, where virtualization support has been improved significantly. Besides, the network stack has received several enhancements. The new core has been accompanied by newer versions of QEMU and Libvirt.
  • QEMU-KVM has been updated from version 2.0 up to version 2.6, while Libvirt has been upgraded from v.1.3 to v.2.5. The main change introduced at QEMU is that the performance of the virtio devices emulated by our hypervisor and used by guest OSs has been increased.

3. Storage

SIM-Cloud utilizes a software-distributed storage based on Ceph. One of the improvements is that the storage has been upgraded from Hammer to Jewel version. Apart from the enhanced storage performance in general, the new releases boasts the functionality that speeds up the user disk backup creation process as a part of the backup service powered by SIM-Cloud BaaS.

4. Cloud backup service

We should also speak about the successful operation of the cloud backup service called SIM-Cloud BaaS. Those of our clients who have already taken advantage of this service enjoyed all benefits of us creating cloud backups for their business-critical data despite the recent outburst of cryptographic viruses. It is important to note that the data are copied to an area separated from your basic infrastructure, while the backup process set up by our seasoned tech support professionals guarantees that your information remains integral and up-to-date in case of an emergency.

5. Public API

As a part of a recent major update, we have also performed a test run of a public API that enabled our customers to manage the cloud services. Shortly, SIM-Cloud users will be able to manage their infrastructure resources in the cloud both via the Horizon dashboard and via a software interface.

6. IPv6 implementation

As you may recall, the IPv6 protocol was introduced in SIM-Cloud early June. This is a modern and essential technical solution that is very popular among high-technology companies operating in the realm of web development and public services as well as among corporations that have deployed their infrastructures in the cloud. Compared to IPv4, the IPv6 protocol facilitates better online scalability.

All in all, these updates are not the last ones to be introduced by SIM-Cloud – we are still working to improve the functional capabilities of our product and introduce new services designed to facilitate easier, simpler and more appealing way for our users to work with the cloud.
