New release of our cloud IaaS – SIM-Cloud version 4.0

New release of our cloud IaaS – SIM-Cloud version 4.0

We continue to upgrade our cloud IaaS product, and this is the new release, SIM-Cloud 4.0, has been presented earlier in the 2019 year. The new cloud IaaS version has been deployed, tested, and now it works for our customers.

All of the main components of the redundant SIM-Cloud IaaS were improved.

Also, we began to develop a new, more convenient documentation for SIM-Cloud.


Our SIM-Cloud Team got great results from the implementation of new software tools to improve monitoring and analytics functionality. It gives us more opportunities to manage and support external and internal SIM-Cloud services, that provides you with stable operation of your projects.

We’ve added new OS images:

  • bionic-server-cloudimg-amd64 (Ubuntu server 18.04 LTS) 
  • Kerio-control-appliance-9.2.7  
  • FortiGate VM 6.0.2 
  • FortiGate VM 5.6.6
  • openSUSE-Leap-15.0 OpenStack.x86_64-0.0.4

We’ve also upgraded our Backup-as-a-Service cloud product (SIM-Cloud BaaS):

  • back-up performance indicator has been added;
  • snapshots creating procedure was optimized;
  • Beta-version of our new cloud feature Notification-as-a-Service (SIM-Cloud-NaaS) is ready to test and use.

Data storage Ceph is upgraded to the Luminous version for more stability and performance.

Storage disks use hardware-based encryption Increasing your data protection to the new level.


SIM-Cloud IaaS v4.0 is based on the Linux OS. Now, bare servers’ nodes use an upgraded version of the Ubuntu 16.04 LTS (Xenial Xerus). Using this version of the OS guarantees all current updates within 5 years. The Xenial Xerus release has the following main changes:

  • Stability and performance are increased;
  • Standard distributive applications list is updated, and new versions of those apps are added.

Well-proven QEMU KVM v.2.10.2 module, loaded into the Linux kernel, is still used for the virtualization.

SIM-Networks technical experts have developed and implemented a new monitoring service Cloud-Mon for automated controlling of virtual routers in customers’ projects deployed in the SIM-Cloud IaaS. This service contains:

  • vRouters availability monitoring;
  • vRouters accessibility control.

The essentials of this microservice are background data collection and analysis from vRouters, intelligent control, and correction of routers settings to avoid failures.

SIM-Cloud network infrastructure was enhanced:

  • Network key elements were scaled-out;
  • Open vSwitch components at network nodes were upgraded.

We’ve migrated all of the customer’s projects to the new network topology, with the virtual router as a centralized traffic exchange point. It enables additional isolation of virtual instances and provides with a new security level, scaling functionality and flexibility.

You can also increase the manageability of your network using a floating IP, which can independently and flexibly be assigned to your instances to access them from the public segment of the Internet. Now you can optionally use dedicated public subnetworks in your virtual network, and announce your own IP spaces to your cloud infrastructure.


Our top-of-the-line product, SIM-Cloud IaaS, is based on the dynamically going forward IT platform OpenStack. Following the latest upgrade, the new version of Ocata has been changed by the Pike release.  The essentials of the OpenStack Pike release:

  • an emphasis made on improving basic features instead of many additional options and features;
  • a conjunction of various computing and network resources from various vendors to resource pools made easier and simpler. Open source software, hardware, and virtual equipment of different vendors as chosen by the user are among them;
  • the modular architecture allows to add to the infrastructure functions you need right now or disable something that is unused for now.

Main advantages of the OpenStack Pike:

  • increased performance, simplified management, the latest version of the Python 3.5 is also supported;
  • useful and simple deploying, scaling and upgrading of the Cloud IaaS software – on the fly;
  • stable operation and maximized the security of cloud users.

You can find brief descriptions of key microservices improvements made by OpenStack developers below.

  • Horizon, a graphic user interface upgraded in the SIM-Cloud IaaS to the Queens version, has some changes in a dashboard:
  • Volumes tab is placed to a separate section;
  • An option to set a Security Group to the instance port (interface) is added;
  • An option to set a required IP address to the instance port during its creating is added, too;
  • API Access tab is placed to a separated section;
  • Some other GUI elements are added too – take a look at the picture below:

  • The virtual machines control service Nova at the Pike release has improved a large-scale deployments support:
  • Cells internal system design is upgraded to the v.2 to avoid limitations during a databases scaling process;
  • Text messages protocol has been changed and simplified.
  • The OpenStack Block Storage Cinder has got the following new options:
  • a revert to snapshot function allows backing to the saved status of an instance;
  • some storage types have an ability to increase volumes capacity on-the-fly, without instance delaying, that is very important for online applications.
  • The NaaS (Network-as-a-Service) OpenStack Neutron has some improvements, too:
  • working stability and performance are increased due to server workload reduction;
  • Upgrading from Ocata release without downtime has been added.
  • OpenStack bare metal provisioning service Ironic helps to improve integration with OpenStack components deployed on bare metal machines.

We have been systematically enhanced and expanded SIM-Cloud computing resources, so you can scale your projects seamlessly.

And don’t forget that our Customer Care is ready to serve you around the clock!
