Infrastructure as a Code
tcp cloud deploy innovative IT infrastructure built on the OpenStack, Kubernetes and other open source projects!
Just download our tcp cloud Mk.20 release and start manage your infrastructure as a code!
Give us any contact you want. We'll reach you soon!
Our blog post explains open source IoT platform introduced at OpenStack Summit Keynote at Austin in more detail. First we explain our approach and vision to IoT, technical overview and show two sample use cases.
As private cloud (primary based on OpenStack) deployers and integrators lots of customer ask as about support of IPv6. Most of our deployments run on OpenContrail SDN&NFV. Reasons are described in our previous blogs (http://www.tcpcloud.eu/en/blog/2015/07/13/opencontrail-sdn-lab-testing-1-tor-switches-ovsdb/) . OpenContrail SDN supports IPv6 for quite long, but there is not so many real tests. Therefore we decided to share procedure how we configured and used IPv6 in OpenStack.
Kubernetes brings a new way to manage container-based workloads and enables similar features like OpenStack for VMs for start. If you start using Kubernetes you will soon realize that you can deploy easily it in AWS, GCE or Vagrant, but what about your on-premise bare-metal deployment? How to integrate it into your current OpenStack or virtualized infrastructure? All blog posts and manuals document small clusters running in virtual machines with sample web applications, but none of them show real scenario for bare-metal or enterprise performance workload with integration in current network design. To properly design networking is the most difficult part of architectural design, just like with OpenStack.
Today I would like to share with you my story about installation OpenStack service Swift with Keystone authentication. Swift is a highly available, distributed, eventually consistent object/blob store. More info at http://docs.openstack.org/developer/swift/
In this blog we would like to show how to integrate physical F5 under OpenContrail SDN and create Load Balancer pools through standard Neutron LbaaS API.
Load Balancers are very important part of cloud and OpenStack Neutron has enabled to use LbaaS features since release Grizzly. However upstream implementation with OpenvSwitch/HAProxy does not provide High Availability by design. SDN OpenContrail provides HA LbaaS feature with HAProxy...
OpenStack is, without any doubt, a huge ecosystem of many coordinated services. Rally is a benchmarking tool that hepls to answer following question: “How does OpenStack behave at different scales?”. To make this possible, Rally automates and unifies OpenStack deployments, cloud verification and benchmarking.
Rally does it in a generic way, making it possible to check whether OpenStack is going to perform well on, let’s say...
Now it’s time to vote for speakers!
This week you have a possibility to choose the most exciting presentation, which perform at OpenStack Summit in Tokyo. The end of voting season is July 30, 11:59 PM Pacific.
Please help us and vote for our session...
Nobody doubts that OpenStack is the best open source project for private and public clouds today. OpenStack has begun to be perceived as a standard platform not only for laboratory or development environments, but has became suitable for large enterprises and service providers as well. This OpenStack revolution brought along a new topic called SDN. Software Defined Networking (SDN) can be seen as kind of buzzword and lot of our customers thought that they did not have a need for SDN, because their environment is not large enough, too dynamic, etc. But SDN is not just about scaling, it gives you opportunity to use NFV (Network Function Virtualization) like LbaaS, FWaaS, VPNaaS...
If you are familiar with Openstack cloud platform, you have definitely seen OpenStack Dashboard for managemement of various resources and parameters of the cloud, but if you are a Django programmer, you will probably see Horizon framework features on which actual OpenStack dashboard is built upon. This blog post targets Django Developers, not much Openstack end-users. Someone can say that changing logo or add some panels or dashboards is topmost expectation for Openstack Dashboard tuning...
11th OpenStack Summit took place in Vancouver during penultimate week of May, which is among the largest open source conferences with almost 6 thousand attendees. OpenStack Summit is held twice a year, and follows the arrival of the new release and offers many interesting technical and business lectures.
The summit in Vancouver was special for us, it was for the first time, when representatives from Czech Republic...

Cloud Software Engineer,
Cloud Sales Engineer
Today I would like to try answers regarding networking on hybrid hypervisor environment. Vanilla Neutron implementation using openVSwitch cannot be used with VMware infrastructure. Only Nova vCenter driver (ESXi driver deprecated in Icehouse release) for compute exists, Cinder VMDK driver for volumes. For the networking virtualization only Nova flat networks can be used. Of course, there is an effort to provide at least Neutron VLAN driver, but the development is done outside the OpenStack community. The reason is that VMware forces customer to buy its SDN solution VMware NSX and use Neutron NSX plugin...
