Time to understand the difference between the four main types of cloud computing
To get the best value out of a Cloud solution, it is necessary to evaluate the effectiveness of current solutions, identify the business objectives these solutions are failing to meet, and evaluate those results to define a Cloud solution that truly suits your organization and its goals the best.
Below is a quick overview of the different types of available Cloud solutions and what may be the best fit for individual use case.
Many considerations go into managing different applications because of their requirements. It is critical to decide which Cloud solution - public or private - to deploy. We will therefore compare the advantages and disadvantages associated with these solutions when it comes to cost, maintenance, scalability, reliability, and security:
For public cloud, it is not necessary to buy either hardware or software. Flexible pricing models make it easy to pay only for the services you use. Private cloud, on the other hand, can be more expensive, with a higher total cost of ownership (TCO), due to storage, maintenance, and software licenses.
Hybrid cloud solutions have been shown to reduce long-term IT costs. Nevertheless, one should be aware of some type of costs when considering the transition to a hybrid cloud environment: Management costs, data transfer costs, adaptation costs, integration costs, storage costs and platform costs.
Multi-cloud platform can provide a unified experience across multiple vendors. A single operating point across several cloud solutions will provide important visibility and control of the entire IT solution. This is cost-effective because existing systems are streamlined and contribute to better resource utilization.
As a customer of a public cloud solution, you obviously do not need to think about maintenance. The provider takes care of maintenance and manages the infrastructure. For private cloud, on the other hand, one must be aware that it requires good planning and expertise and can entail extra costs if one is to upgrade the infrastructure without affecting business processes.
In a hybrid cloud, there are strategies and tools that can help simplify the maintenance and management of a hybrid environment. These are methods that create a streamlined approach across environments, where a cloud service provider can help.
A cloud service provider is required to maintain a multi-cloud solution. This can lead to complications and force an adaptation of the processes as the companies' data is moved across different cloud platforms.
Public cloud solutions are highly flexible and scalable, and able to meet changing workloads by increasing or decreasing the resources required at any given time. For private cloud solutions, however, limited scalability can make it difficult to meet unforeseen needs. The capacity of local data centres can be a limiting resource.
Hybrid cloud provides more resource opportunities via public cloud providers, compared to a physical data center. The hybrid solution therefore makes it easier to supply, implement and scale resources to meet periods of increased demand.
For multi-cloud, scalability is about being able to provide flexibility in the form of keeping an application in a private cloud infrastructure but combined with the ability to move to a public cloud to gain extra capacity if necessary.
Public cloud solutions are characterized as highly reliable and consist of a large network of servers that ensure that errors are avoided. For a private cloud platform, the reliability aspect is often affected by the fact that mobile users may have limited access, due to strict security measures.
A hybrid cloud approach provides both predictability, increased reliability, and better security, since the most sensitive data can be stored in a more closed and controlled private cloud environment, as an extra layer of security.
The multi-cloud approach can help you reduce the chances of major IT disasters, as not all eggs are laid in the same basket. Thus, it also ensures better reliability.
It is important to consider the advantages and disadvantages of the various cloud models and to be aware that many companies must continue to relate in full or partly to traditional operating models. Then the choice of cloud platform can be a consequence of the individual company's application portfolio. Many people rely on applications that can not be moved, or that there is nothing to gain from moving to the cloud. Then the right focus should be application modernization.
