Good "pipe" mixed data center

In an era of cloud computing, where companies are already generating an unrivalled trust in cloud computing, companies are now starting to expand their data centers with public clouds, mixing public and mixed cloud hosting and local it, and this seems to be a very effective approach.

The Mixed data Center environment has become a hot topic recently at a modern infrastructure decision-making conference in New York.

At the meeting participants, there was a divergence of views on the use of mixed data centers. While large government agencies have high data security requirements, the cloud remains the first option, and corporate finance continues to rely on local it for the use of the public cloud remains conservative.

The hybrid cloud of Amazon Web services and VMware virtualization has been applied to Comcast (Comcast: America's main cable TV, broadband network with IP telephony) as an example. According to Charles Hammell, the company's solution architect, it is clear that the cable company still favours the public cloud.

"For proof-of-concept or if you have a good idea and want to build quickly, the public cloud is the way," Hammell said. "Getting products into the market quickly is also one of the benefits of applying the cloud." ”

Other companies, such as the HR company Robert Half Analysys, are largely dependent on the cloud.

"We have four production applications, all of our data analysis is in the public cloud," said Sean Perry, who is the CIO of the company, "we seize the opportunity to apply the public cloud, our AWS Bill is very large." ”

According to TechTarget's 2013 Cloud Plus survey, in fact, according to the needs of the enterprise, although the public cloud services occupy a large percentage, but there are still many ways to "split" the data center.

The survey, which involved 1200 respondents, found that 39% use a public cloud, 28% use a private cloud, and 33% use a hybrid cloud.

Part of the appeal of the hybrid cloud approach is that the hybrid cloud provides a better mix of public and private clouds, it can reduce its load of operational tasks, and it can maintain the platform.

"The more we shrink in legacy applications, the more resources we have on innovation," said Dave Castellani, the CIO and director of the New York Life Retirement program service.

Compared to software upgrade costs and annual subscription licenses and maintenance costs, the cloud subscription model is more meaningful in many cases.

Another New York Life CIO, Neal Ramasamy, can get at least one traditional software provider in this model to follow.

"We made a deal with the workflow providers, and after 18 months of negotiations, we forced them to provide us with the SaaS model, not the software and maintenance model," he said.

He says the cost savings in this approach is 40%, and they are now looking at subscription licenses from other software providers.

Mixed Data Center decision point

However, IT managers who work on the ground in the data center say they prefer the local IT environment because they retain full control.

However, due to energy consumption, space and refrigeration constraints, this control also has capacity constraints. In addition, the runtime may not be as good as high availability because of this limitation, and the loan options may be limited, says CTO and co-founder Craig Macfarlane of transitional Data Services, who has a speech at the meeting Describes the proper extension of the infrastructure through local load, hosting, managing services and cloud resources.

Overall, the benefits of a hybrid cloud approach include more efficient application of it and a scalable workload that emphasizes business agility and strategic use of it talent.

Managed and managed service providers offer higher uptime commitments, better bandwidth choices, and 7x24-hour management.

Mixed cloud data centers bring efficiencies as well as challenges, and the application of applicability and the lack of integration between the interoperable/private cloud and the public cloud are problems. In addition, the application may require extended modifications.

It pros also say the complexity of managing a mixed environment is also a problem and may require additional monitoring tools.
