As an emerging research and application field, cloud storage is being used by more and more enterprises due to its advantages of rapid deployment, low cost, and flexible scale adjustment.
CloudStorage (CloudStorage) undertakes the task of collecting, storing and processing data in the form of services at the lowest level, and on the basis of this, it unfolds the upper-layer cloud platform and cloud services.
Public and private cloud infrastructures are flexible, scalable, and relatively inexpensive. However, each cloud implementation has its own familiar and little-known shortcomings.
Many IT professionals believe that private cloud storage is just another name for its current infrastructure, as is public cloud storage, but only in a company's public data center. Vendors with these ideas often lack cloud storage infrastructure technology or try to catch up with other markets in technology.
The traditional IT infrastructure divides the data center into multiple functions: applications, computing, networking, storage and facilities, and expertise. Isolated data center infrastructure is very beneficial for slow-growing, non-dynamic, predictable workloads. This type of infrastructure is responsible for predicting buyer computing, network and storage requirements (such as throughput, IOPS, capacity, network bandwidth, and traffic) during the infrastructure lifecycle.
Private cloud or public cloud storage infrastructure uses options with elastic computing, networking, and storage capabilities. This change is often slow and expensive, so the risk usually belongs to the acquirer. To meet user requirements, most IT professionals mistakenly overestimate and over-provision their storage infrastructure, which leads to higher costs and prevents unpredictable demand from exceeding the capacity of this infrastructure because it is none Flexible and not easy to change.
Advantages and disadvantages of public cloud storage infrastructureThe public cloud infrastructure is multi-tenant and shared. It seems to be infinite for any given user because they can expand the resources of their unexpected workloads as needed and shrink as demand decreases. In reality, these resources are oversubscribed, allowing service providers to obtain reasonable profits. This is conceptually similar to oversubscribing a virtualized server. Statistically, it is unlikely that all tenants or users will need infrastructure resources at the same time, but this has happened, but only very little. Tenants are protected by service level agreements and can provide some payment compensation if they are unable to obtain the services they pay.
However, there are several public issues with public cloud storage infrastructure.
·safely control. The public cloud is fairly secure and the problem is controllable. In terms of high compliance, regulatory industries such as healthcare, insurance, financial services and government agencies cannot be outsourced because of compliance obligations. These organizations can use a public cloud infrastructure, but they still need to be responsible for ensuring compliance. Few companies are willing to give up the ability to manage and control data security because service providers fail to waive their responsibilities.
· It is not possible to fine tune application workload performance directly. There are ways to manage workloads to a single point, just as the infrastructure is an on-premises data center or private cloud.
· Long-term costs. The short-term cost of a public cloud is often lower than the private cloud investment cost, but the long-term cost may be higher. Administrators complain about hidden or unexpected costs of reading or moving data; however, many organizations tend to manage their business and business applications, rather than their base can be attributed to no data center or smaller data center, Significant cost savings.
· Data stickiness. Once tenant/user data is in the cloud, moving it out or changing the cloud service provider often becomes difficult and inconvenient. As the amount of data in the public cloud increases, the difficulty of changing providers or pulling data back to private clouds increases.
·future. What happens when a public cloud provider becomes so oversubscribed that it is no longer acceptable? Worse, what happens if they become unable to pay?
Is a private cloud a better choice?
Private cloud infrastructure uses the same technology as public clouds :• A hypervisor or container for software-defined calculations.
• Open flow switch, network function, virtualization and application control network controller for software defined networks.
Software-based storage in the hypervisor kernel, or software storage running on virtual machines or devices that define storage.
These private cloud infrastructures support local security and performance control. There are no questions about provider solvency, oversubscription or data stickiness. Its cost is predictable and long-term decline. If security/performance control, compliance management, and lower long-term costs are key issues, private cloud infrastructure can be a way out.
Private cloud infrastructure still poses risks to buyers of infrastructure, although technology has reduced risk. Flexibility is limited by the available physical resources. Technical refresh issues may still exist, depending on the vendor, as well as vendor lock-in.
As with all technologies, there is no perfect answer. Which type of cloud storage infrastructure is most effective for a particular organization depends on its specific requirements.
