Cloud computing Hits: How do companies choose IaaS providers?

When people think of cloud computing services, the easiest thing to think about is the infrastructure. and http://www.aliyun.com/zixun/aggregation/13590.html "> Infrastructure services (IaaS) can provide customers with the services that operators run on the cloud infrastructure, Users can access the client interface on a variety of devices, such as browsers. Consumers do not need to manage or control any cloud infrastructure, including networks, servers, operating systems, storage, and so on;

IaaS is a completely independent product, with SaaS, PAAs and called Three service modes. IaaS is divided into two uses: public and private. Amazon EC2 uses a common server pool in the infrastructure cloud. More privatized services use a set of public or private server pools within the enterprise's internal data center. If you are developing software in an enterprise data center environment, both types are available and the cost of using EC2 to temporarily extend resources is low-for example, testing. Use both to develop applications and services faster and shorten development and testing cycles.

At the same time, IaaS also has security vulnerabilities, such as the provider of a shared infrastructure, that is, some components, such as the CPU cache, GPU, etc. for the users of the system is not completely isolated, which will have a consequence, that when an attacker succeeds, All servers open the door to attackers, and some client operating systems can gain access to the underlying platform without control, even with hypervisor. Solution: Develop a strong zoning and defense strategy, and IAAS vendors must monitor the environment for unauthorized modifications and activities.

Compared to private cloud infrastructure servers, the infrastructure servers of the public cloud choose to be more cumbersome and cautious, so how do companies choose their own IaaS service providers for cloud providers?

How do companies choose IaaS providers?

Public cloud infrastructure services, refers to a virtual machine, storage and network services, has been repeatedly proposed many times, to meet the needs of enterprises. The reason for his being a public cloud is that there are many virtual machines that make up the basic design services of his virtual machines.

If you don't think it's a good idea, then you might want to consider a private cloud or a hybrid cloud.

Even if you are an outsourced infrastructure, you will still have some settings for managing virtual machines, which means that public cloud providers manage the components of physical hardware, power supplies, cooling systems and data centers.

While cloud computing may be a short-term tactical move, moving to the cloud and transferring data centers is a natural evolutionary process for larger organizations. Although the market is still immature, there are many options, but still have a lot of suppliers may meet your specific needs exist.

Here to provide you with four points of view, so that enterprises in the use of cloud services can have a better choice.

1. Rigorous evaluation. A model of cloud computing is not suitable for all enterprises, today may be a very good solution tomorrow may not be suitable for your business, enterprises in the use of cloud computing time to take into account the pace of enterprise development, therefore, you need to carry out a rigorous assessment of your business.

2. Consider multiple vendors although it is possible that a single service from one vendor can well meet your needs, no vendor can provide the best solution across all business. You need to consider choosing a vendor's environment or business requirements.

3. Think beyond saving. While many companies may look at IaaS as a way to reduce costs, his biggest advantage is in improving flexibility and scalability, not cost savings.

4. The location of the infrastructure is considered. The IaaS of the public cloud can provide services across the globe. But the most advanced suppliers are still located in the US roots.

Summary: So the enterprise in the adoption of IaaS must be considered comprehensive, lest the enterprise in the migration process caused losses, so that the new model can really bring flexibility and convenience to enterprises!
