When we are deciding between public or private cloud implementation there are some capabilities we need to take into consideration and security is one of the top ones. Other characteristics like integration with existing systems, costs and management are also important.
Looking at the management side of a cloud environment, there may be some delivery models that can be used in this arena that can bring new ways into the decision process.
Let me go over three delivery scenarios that can be selected when deploying private clouds:
• The most traditional, and naturally the first to be analyzed, is the deployment of private cloud infrastructure in the company’s datacenter. Everything from hardware, software and management of cloud infrastructure is deployed and maintained by the company. The company must have an entire team to manage and operate it. From a cost perspective this is the most expensive deployment scenario since it requires infrastructure and people to manage it, and in some cases it may pull the company’s focus from its core business.
• A second option is the deployment of cloud infrastructure into the company’s datacenter, but managed and operated by a third party company. This can relieve labor and tooling costs needed to manage it and keep all security aspects of a private cloud deployment inside the company’s domain.
• A third option is the deployment of cloud infrastructure in a third party datacenter. This would be hosted, owned, managed and operated by a third party company. That may sound like a public cloud model, but it isn’t. In this type of deployment the cloud infrastructure is dedicated to the company. So the company would not need to care about all the infrastructure costs and labor to maintain it. Security may be a concern, but usually the third-party companies have high security guidelines and polices in place that can ensure that any security issue is covered. In some cases they have a more secured environment than the one deployed in the company. And being a dedicated cloud infrastructure to the company guaranties the privacy of data kept there.
I tried to give a quick explanation about one important point that needs to be carefully analyzed when deciding for a cloud deployment. All three deployment models have their pros and cons and it is up to the company which one best fit in their strategy. Let me know your thoughts!
