When the enterprise is just beginning to use the public cloud services, the market has emerged a large number of cloud computing providers, the type of cloud computing, the number of service providers, so that enterprises dazzling. So how do our companies choose a suitable cloud provider to get cloud services?

Typically, it takes a few months for the company to look at cloud computing services, but after a lot of comparisons, most companies are frustrated because after the cloud service is finished, companies will find that there are a number of new providers on the tail of the list of service providers, compared to the previous cloud providers, The price and terms of service may have changed again, and some service providers may have been bought or closed by some big companies.

These questions leave a question for IT staff: whether cloud computing is a changing thing. The answer to the question is yes, and all the technology should be changing.

Over time, cloud computing services are categorized into different categories and functions, and are offered to different customers at different prices. Many services are price/function oriented, and the more they are paid on demand, the more they pay. We also see the following emerging cloud services categories, and potential cloud service customers are also looking at how to review the large number of cloud service providers in a short time.

New and bright: cloud computing start-ups

Cloud-computing start-ups have brought a lot of energy to the cloud market, as well as some confusion. Most of these companies provide industry or software-type services, and a significant portion of them are hosting cloud services to third parties.

So what can you choose from these cloud-computing startups? In fact, the risk is the same as the return, because the price and policy of the start-up companies are more volatile, these start-ups are more likely to fail. From this perspective, development and pilot projects can choose these cloud computing start-ups, long-term, key people's projects to choose cloud-computing start-ups is not appropriate.

When reviewing a cloud-computing start-up, you need to consider the difficulty of finding a substitute provider in a short period of time, and the more difficult it is, the less appropriate. For some simple cloud computing projects, considering that no mission-critical applications or key personnel are involved in migrating to and from the cloud, or just as a simple test environment, cloud start-ups are a good choice for functional and price considerations, Today's startups are likely to be tomorrow's Amazon or Google.

How community clouds meet specific needs

A potential category of cloud service providers is the community cloud. The community cloud, like cloud services provided by cloud start-ups, is largely hosted on the infrastructure of large providers. The community cloud differs in that it is targeted, primarily for the industry or for users with special requirements for security, availability, and regulation. Community clouds often add a lot of functionality to the "naked" cloud, comparing the services offered by common public cloud providers with lower tariffs and more functionality.

Under what circumstances can you choose a community cloud? The answer is not obvious, when you are in a clear community.

Companies in the common industry are governed by a common set of regulations, so they can consider sharing and exchanging information in community clouds. Whether the community cloud service providers guarantee any distinction between their products, and in the end will be one aspect of the services provided by the Community cloud services provider for better security, audit compliance and certification, or does it have no proof to support his commitment?

There are two determining factors in choosing a community cloud, the first is that your company is indeed a member of the community that is being serviced, with the same problems and concerns as other members. The second element to be noted is the need to troubleshoot compensation contracts for Community cloud service providers.

Operators-Cloud service providers

Cloud-computing start-ups and community clouds can be considered by operators if they are not meeting your business needs. Many telecom operators are now joining the ranks of cloud service providers, and although the services they offer are expensive, they have two distinct advantages that are important to your application.

Operators-Cloud service providers can not only provide cloud computing services, their network transport capabilities can also help you accelerate access to cloud services. If your company has IP VPN, then vendors are likely to connect your VPN to cloud services and write a more specific service level agreement (SLA) for the cloud service experience. Operators-Cloud service providers are also more aware of the importance of service reliability and availability than other vendors, so choosing an operator will reduce your downtime.

So how to choose the operator? Typically, you should choose a telecommunications service to provide the broadest range of operators. Also consider the location of the operator's infrastructure and choose an operator who can provide the best service for your data center. If you build a hybrid cloud, it's particularly important to maintain a connection between your corporate private cloud and the public cloud.

Last line of defense: Price and contract for cloud services

At the end of deciding which cloud service provider to choose, consider the service pricing details. Many cloud service providers have a very specific level plan for pricing services that will eventually affect your total charges.

Many cloud applications require data storage, often related to cloud hosting data queries, so for data storage pricing terms to pay special attention to the flow of the charges should also pay particular attention. These data fees grow beyond the basic CPU usage fee, so don't wait until the bill arrives to regret it.

Finally, remember that no service is good without a contract. Do not make it your choice to provide a cloud service provider with a defined contract and financial situation.
