It is undeniable that setting up a private cloud on your data center can be really challenging. Private cloud means the power of on – demand computing together with the difficulties to build technical solutions that can adapt to your specific requirement. With a private cloud storage, you must carry out different processes on your own without support from such vendors as Amazon Web Services and Microsoft Azure. More precisely, you have to store data on your local center and to some extent, it will come with much savings for your expenses.
Nevertheless, every garden has weeds. Private clouds are also bringing about so many challenges. With a private cloud storage, your organization may have to deal with risks and even when they are hidden. This article is going to present some of the risks that you can meet when adopting private cloud together with some solutions which you can follow.
The first risk: problems related to security
On the public cloud, when it comes to security, the responsibility is shared between the cloud provider as well as the organization that is getting services. To be more specific, what takes place in your virtual machine will be transferred to your responsibility and physical hardware, virtualization as well as cloud services are the responsibility of cloud vendor.
It is so surprising that a private cloud may be less secure compared to a public one. For such a long time, public cloud vendors have gained a lot of experience in safety as well as other things like strategies, techniques and tools which are utilized to secure numerous layers of the cloud storage. It is obvious that the public clouds are easier to be attacked by hackers yet their cloud providers know clearly what to do to deal with the problems and reduce them.
Another thing to take into consideration is hybrid clouds, which have been so famous recently. Safety in a hybrid cloud gets more intricate than ever. When you migrate your data from the private cloud storage to the public one, you should think of how to expand the safety from your private data center to the public one. Of course, this is not an easy task at all.
Issues related to performance
As you may have known, performance has been a big concern in virtualized environments. Due to the fluctuating characteristic of the environment, it is really challenging to predict how the workloads may change in the future and how it could have impact on the performance as well as user experience.
In the public cloud, it is clear that you have how many machine instances as well as compute resources. However, there are other aspects influencing on the whole performance such as latency, disasters or common compute resources, bandwidth of the network, surrounding environment, shared access to the same resources as well as services and so on.
On the contrary, with the private cloud, you are provided with higher flexibility to set up your own cloud. You are able to choose the hardware and software components that fit your needs and everything that you suppose to be able to optimize your performance. However, the truth is more complicated.
If the public cloud providers sometimes find it hard to deliver suitable performance that their customers are in need because of the sophistication and fluctuation of infrastructures, with private clouds, sometimes you can not adapt to the changes to reach your performance target. Hidden risks may suddenly take place in virtualized systems so that the performance is changing every time in accordance with your workloads, software updates from Open Stack or other factors causing from the systems and so on. Not everyone makes sure that they can get over all the cases.
A major tip to reduce this threat is to adopt a consistent process availably to push your performance. More precisely, with every deployment, you need to make use of a method to carry out performance check. And it would be more preferable if you can do it in an automatic manner. If you do not have such methods in place, your organization can be led to unprecedented performance risks.
The third risk: Knowledge and learning curve
Private clouds have already turned up for a time and today a lot of private cloud storage solutions are set up through taking advantage of the software infrastructure of VMware, which is rather famous and has a large number of customers. Nevertheless, there are a lot of private cloud projects choosing the strong but lower cost offerings from open source platforms. And such solutions as Open Stack is evolving as the new solution.
If you do not have an employee who is good at dealing with Open Stack, it would be so difficult for you to have a project from this source. From a survey of this organization conducted three years ago, users claimed that there is much difficulty and sophistication of dealing with Open Stack even though the platform is developing more. If you do not carry out the process rightly, this may have an impact on your capability to set up private cloud storage that meets your specific requirements and needs.
The final risk: Visibility Lack
One of the most popular reasons to migrate your data from public cloud to the private cloud storage is to improve more visibility for users into what is taking place within the cloud. Of course, when you store your data in your own data center, you will gain much higher visibility abilities into such aspects as workloads, traffic and performance.
On the contrary, in the public cloud, you may not find such a solution to gain the visibility to your network. Current monitoring tools such as Amazon Cloud Watch will not allow you to take a look to prevent the security issues. However, in the private cloud storage, you will also cope with such problems related to traffic between virtual machines that may lead to lack of visibility.
