How the Cloud ages to survive in the big cloud

While many companies are just beginning to use cloud computing, some have already started using the technology early. In fact, in the latter part of the enterprise, you create a large private cloud that supports its main business.

These mega-clouds pose special challenges for CIOs and executives in the enterprise. Administrators need to maintain service levels, ensure that systems hosted on the cloud are secure, and deploy new solutions in ways that are of interest to internal customers. As cloud computing is relatively new, in the process of deploying these high-capacity http://www.aliyun.com/zixun/aggregation/14162.html ">it architectures, enterprises must learn how to deal with the problems that arise."

"For me, the biggest challenge in implementing a private cloud is the transformation of the culture and business model from the ' work for the user ' model to the self-service model of the user," said Frank Gens, an analyst at IDC. From design to deployment and operations to support, the entire IT service delivery model needs to be carefully and thoroughly examined. ”

When implementing and using a service based computing infrastructure, businesses need to address the following issues related to large clouds.

Integration with legacy systems

The integration of private cloud with existing IT systems is a key issue, and it is not possible for an enterprise to complete a transfer to a cloud environment overnight.

Jordan Becker, vice president of Bae, says the consolidation of the new and old computing environments is a key challenge, as the cloud infrastructure being created by BAE Systems will gradually replace the data centers currently being used by companies and customers.

BAE Systems, a defense and security firm based in Arlington, Virginia State, operates a multi-tenant private cloud for government and military clients. The system contains a storage system with a capacity of several P bytes, but Bae declined to say how big the cloud was.

BAE vice president Jordan Becker says Bae also uses a smaller private cloud in-house to develop and test systems. This small private cloud is created for customers.

BAE is creating a cloud infrastructure that will gradually replace the data centers that companies and customers are currently using. Therefore, the integration and migration between the new and the old computing environment is a problem that BAE has to solve.

"Private cloud deployments are relatively new and they have not replaced existing data centers," Becker said. "But private clouds are helping to slow the growth of legacy data centers," he explains. As the natural capital renewal cycle of the legacy data center infrastructure is nearing completion, the infrastructure will gradually be replaced by cloud infrastructure. This process will last for several years. ”

"In this transition, we need to flex our legacy data centers so that applications that run on old data centers can be transferred transparently to the cloud," Becker said. From the standpoint of application and management, you should pay attention to the user, just like the virtual infrastructure. ”

To be able to integrate, BAE Systems creates a universal global namespace for its image data. The data includes two-D images, files with stereo, files that contain full dynamic video, and metadata that is associated with these images.

"The Universal namespace is unique to every particular customer group," he said. A customer group that shares a common namespace is comprised of users who use these geospatial information in several defense and intelligence agencies. ”

The private cloud is now connected to legacy data centers and file architectures developed for stand-alone applications, because BAE deploys the common namespace for the private cloud, so customers can access this information and seamlessly integrate information with the peer organizations they want to work with.
