Five tips for cloud computing transformation

Ten professional skills of cloud computing

1. Understand Cloud Computing

Johan Goossens, head of the technology and human factors department of the NATO Allied Transformation Command (ACT), recommends training personnel on the principles and definitions of cloud computing before transitioning to cloud computing.

He said: "We started training on cloud computing in the summer of 2010. We communicated with our partner vendors to let us understand the terminology of cloud computing."

2. Know your application

New York health insurer EmblemHealth's chief technology officer Pedro Villalba said: "Before we transition to cloud computing, we are convinced that we have understood our applications."

He said: "We first distinguish which applications can improve the business, and then determine which applications require an independent environment. We found that due to design reasons, some applications cannot be used in cloud strategies unless they are completely redesigned."

Villalba said that after completing the classification of applications, he has a deep understanding of which applications can work well in a virtual environment.

3. Summarize typical business cases

Mark White, Chief Technology Officer of Deloitte Consulting, said: "Cloud computing is not magical, nor is it a panacea, it just runs technologies that have certain advantages. As with any other technology, especially when you are testing , We recommend that CIOs use business instances as the first experience of cloud computing. "

White said: "The advantage is that the public cloud can provide you with the first experience of migrating workloads to the cloud, which is like crossing the river on your toes."

Factors such as cost, expected return on investment, difficulty level, service level agreement (SLA), expected performance, and service characteristics need to be comprehensively considered. In addition, how to evaluate these afterwards should also be considered.

David Linthicum, chief technology officer of Cloud Computing Consulting's Blue Mountain Lab, agrees. He said: "Most of our customers have technical prototypes, we recommend them to do so."

He said: "If someone came to me and said," We want to solve our storage needs through infrastructure as a service (IaaS). "I would say to him," That's good, but first let us figure out from theory that IaaS is What, then we look at the business case again. "

Linthicum said: "This is the best way to understand the performance of cloud computing and how they work in your environment. You may be able to spend thousands of dollars and some effort to try it. If you choose the right solution, then You will save millions of dollars. "

4. Set reasonable expectations

If you plan to build a private cloud, you want this private cloud to be as simple as Amazon Elastic Cloud (EC2). James Staten, Vice President and Chief Analyst of Forrester Research, said: "Go ahead and allow your users to get self-service authorization to enable them to deploy applications within 15 minutes, but set up a reasonable Expectations. "

For example, the IT department should clearly give four warnings to application developers: some workloads will be restricted to running on private clouds; cloud computing SLAs are similar to what users get from Amazon, not similar to company data centers, which means Therefore, if a private cloud application crashes, they should not call the IT staff at two in the morning; they must set a deadline for the workload; running the workload on the private cloud requires payment to your department.

He said: "After these clarifications, many companies may understand that" once your request is approved, you can deploy the application within 15 minutes. " "But this is not the case for IT staff, because it is just wishful thinking. These approvals may come from the enterprise's architect, application development manager or other personnel."

Staten reminded that if your private cloud looks or feels very much like Amazon's EC2, most R & D staff will turn there. He said: "This will hinder the expansion of the virtual machine if you don't have a reasonable charging model. For example, this is like providing them with a free EC2, in this case, they have no reason to leave. So you It will only increase virtual machines, not decrease them. "

5. Choose a convenient way to deploy a private cloud

Staten said that in other words, it is to purchase an integrated package cloud service (cloud-in-a-box). He said: "Given the urgency and priority of cloud computing, it is wise to do so."

He explained that there are two types of integrated packaged cloud services. One is the software cloud integration package, and then provide specific hardware and infrastructure for this. According to the scale of cloud computing, the cost of this method is between 10,000 and 50,000 US dollars. Staten said: "We recommend that IT departments start with as little cloud as possible to facilitate exploration and gain experience."
