Any company looking to access better IT resources without necessarily having to engineer their entire infrastructure will consider cloud computing. However, before you can jump onto cloud infrastructure, you need to determine which path is right for you. The route you choose to take will be dependent on the needs of the company itself and the constraints it may be facing.
There are three different routes that one can choose when it comes to virtual infrastructure:
- You can go with private cloud for this you will need to have the necessary financial resources to set up your own virtual network. When considering this route you need to be sure that you will be able to handle whatever virtualization issues that arise.
- You can go with public cloud this is usually a much cheaper option. However, many people are concerned about virtualization monitoring and the risk of a security breach with this option. Highly sensitive information and company data may be at risk.
- You can go with hybrid-cloud This will give you the very best of both public and private cloud.
By blending the elements of public and private virtualized hybrid-cloud infrastructure, the company is able to enjoy all the benefits that come with a virtual network. Basically they will be using a private cloud primarily, but when the need arises, and it makes sense, the company can also tap into the public cloud. This particular model will provide better security when it comes to sensitive company data, while reducing costs and increasing efficiency.
Migrating to the Cloud
Since every company has its own history, selecting the choice to go with can become challenging. There are various practical virtualization problems that must be taken into consideration. It is in light of these issues that the hybrid model becomes a great idea.
Several surveys carried out in regards to cloud migration have shown where the concerns for most companies are:
- Compliance and security are a big concern for most companies. An example is the banking sector that is banned from having any of their information on the public cloud.
- Trouble with migration is another reason why companies are hesitant to make the move. Some companies said that the applications they used are mission critical and could not risk moving them. They also felt that the conventional architecture currently in place was more stable.
- Cost was another factor for most companies who felt that the cost of licensing new software was prohibitive since some of them come with a monthly fee attached.
Why Should You Go with Hybrid?
There are several reasons to go with a hybrid solution. For most companies not all applications should go on the cloud. Here are just a few reasons why hybrid solutions are a great idea.
- Increased agility With the cloud you will find that there are always resources available that are just waiting for the client to use. This makes provisioning and de-provisioning very fast compared to a physical server. Rapid deployment of networks is critical if a company is to remain competitive. You can therefore take advantage of the cloud while keeping mission-critical applications in-house for security reasons.
- There is increased automation This means that system administrators do not have to worry about virtualization troubleshooting and the like. They can focus on such things as security and on how they can improve on the efficiency of their VDIs and other existing systems.
- Flexibility and scalability You get to enjoy rapid response in the event of a problem as well as on-demand resources. If there is a workload that needs immediate scaling either upwards or downwards, this becomes easily available too.
Ensuring that the Cloud is Secure
Today, the security provided by both public and private cloud providers is a lot better than it was some 10 years back. It is important that the company carry out due diligence on the security of cloud prior to engaging these services. You should ask questions regarding network monitoring and network troubleshooting as well as the upgrades and patches that you can expect to be done on your system.
Companies are looking to reduce their costs and the complexity of their IT infrastructure in a bid to drive sustainable and continuous operational improvement. The hybrid-cloud offers them a perfect opportunity for the reinvention of IT as they prepare for the next stage of innovation and growth.
