What is the advantage of private cloud over public cloud

The current popular view is that private clouds allow customers to have a total control over all aspects of the cloud service, whether based on the company's own business or the data center hosted by the provider. With a private cloud, customers choose to add multiple levels of security, user authentication, and intrusion detection and prevention systems, while many public cloud sites are unlikely to offer so many options, even if the price is quite expensive. And enterprises can also according to their own needs for the design or components of non-standard networking, and public cloud customers must comply with http://www.aliyun.com/zixun/aggregation/15552.html "> Service provider Standards."

However, customization, regulation and network isolation all require considerable cost. If a company decides to set up its own cloud services, its cost will be quite high, including hiring experienced cloud management technicians to manage the extra costs of a private cloud.

There are, of course, alternative options. Some cloud vendors can remotely provide customers with a completely private cloud infrastructure that allows customers to isolate the entire cloud from any other customer in the data center. This allows you to consider custom cloud services.

The following work involves the related misunderstanding:

Myth 1: Third party hosting private cloud is expensive

While Third-party hosting is indeed more expensive than adopting a standard public cloud solution, their costs are significantly cheaper than a privately managed internal cloud.

Myth Two: Public cloud security is poor

This is actually determined by the providers of cloud services, and the public cloud can be even more secure than the current client network. All this relies on the expertise of resources, money, and the vendor's proprietary cloud model for its operations. Top-tier cloud service providers with state-of-the-art equipment, trained talent, and experience, most companies would be very expensive to hire such a cloud service provider. Plus, the slightest violation of the rules in terms of security performance can immediately and irrevocably destroy the entire vendor's business. The differences in security performance are often determined by such stakes as the tools used, and whether people are more deeply and securely operating than most hosting customers.

Myth Three: Public cloud is not customizable

Although public cloud vendors provide servers, storage devices, memory, and network configurations to accommodate as many customers as possible, there are still a number of public clouds that can accommodate custom services. This service can start with a relatively basic standard. The enterprise can then build its own database, programming environment, or management tools based on the needs of the business, as well as other critical applications, and ultimately migrate the entire business to the cloud environment.

Cloud service providers are of varying sizes. Therefore, there are several factors that need to be considered when choosing a vendor for your business.

Inspection ability

Not all clouds build the same technical capability level. Many potential problems can be avoided if cloud vendors can provide adequate management and monitoring of their cloud resources. Enterprises should fully understand the network, storage devices and access capabilities of the vendor's cloud platform, such as handling burst traffic, improving performance, or new storage devices or memory on line. For some vendors, the enterprise may even manage itself to keep some cloud applications and cloud infrastructure running optimally.

Explore Security and reliability

When considering the deployment of cloud services, enterprises should take full account of the security and reliability of cloud computing. They should thoroughly check the policies of the storage and backup systems, such as power, equipment, or network failures. For emergency treatment in the event of a site disaster. The cloud provider should have an average fault interval time/or ISO9000 reliability rating. Security must not be overlooked. Public cloud providers should be able to fully describe the security features of all the data on their cloud sites.

Easy to use

Enterprises also need to consider whether the complex sites provided by vendors may affect operations. If a solution comes with a complex rate plan, multiple subcontractor systems in different aspects, or resources that the deployment team fails to fully anticipate in the early stages of deployment, cloud monitoring may become "prohibitive".

Putting some or all of your IT business in the cloud is a key commitment for your business. While most businesses have due diligence on industry and customer data, we still have a long way to go. In this spirit, it is also noteworthy that no successful cloud solution can be suitable for all enterprises.
