How do you know if OpenStack is right for you?

Leading IT vendors all want to convince data center administrators that without a cloud, their infrastructure is out of date. But do you really need a cloud to be modern? And what kind of cloud?

Cloud computing offers maximum flexibility on servers. Deploying a server in a cloud environment is easy because it is automated. No need for system administrators for installation. The user can deploy it automatically in minutes.

OpenStack is an open source cloud infrastructure. It comes from the Linux kernel for operating systems, but is not only suitable for Linux applications. The OpenStack infrastructure is open enough to be integrated with other platforms, such as Windows.

This integration is done at two levels. At the bottom level are the processing nodes, which are the servers that host the VMs, called instances.

In OpenStack infrastructures, the processing nodes can be the choice of Linux, Windows and VMware vSphere platforms, for example. And at the top level are the instances that need to be deployed for end users. Any operating system can also be deployed using OpenStack at this level.

Do you need it?

If your data center needs a cloud, be prepared to make complex changes to the IT infrastructure. It will not be enough to install a few servers to have a cloud; you will need to review essential parts, such as storage and network.

Both of these aspects need to be more flexible when you switch to the cloud. For maximum freedom, adopt Software Definition Storage (SDS), which provides easily scalable storage volumes. You will also need the Software Definition Network (SDN) to define subnets that will allow instances to behave as if they are in the same physical subnet, even if they are not in the same datacenter.

Aspects of the software-defined cloud make implementation difficult: Start working on cloud deployment only when necessary, typically when end-users in the data center need flexibility to deploy servers easily. Most of the time, the cloud is not very useful in an organization where server registration follows strict procedures. Your business should be user oriented and have a culture in which the user decides when he needs a new server.

OpenStack infrastructure or other?

OpenStack is one of the most important cloud systems. Most major IT vendors offer it in one form or another, as evidenced by the HP Helion Rack and VMware Integrated OpenStack offerings. But the right cloud deployment platform depends on your environment. OpenStack works well in a Linux datacenter with qualified IT staff.

If this is not the case in your company, consider another cloud option, such as VMware vCloud Air or Microsoft Azure. Thus, implementing an OpenStack infrastructure in an all-Windows datacenter does not make much sense: Microsoft Azure will be able to support integration with less effort.

There are two reasons to choose OpenStack for datacenter deployment: all major IT players integrate their solutions with OpenStack, which means you’ll have the option of choosing the best cloud offer without committing yourself to a lifetime. provider ; and OpenStack is free.

You do not have to pay to create a cloud platform that hosts thousands of instances. As with Linux operating systems, there are also enterprise OpenStack services such as Ubuntu Cloud or Red Hat OpenStack. You can purchase the necessary support contracts in enterprise environments.
