It legacy systems are a big challenge for cloud computing

Oddly enough, the total cost of it is still increasing and increasing. Now there is a lot of talk about the Jevon paradox in the cloud industry, and they argue that reducing costs in goods and services alone, rather than reducing total spending, is actually still an increase in IT spending.

Driven by this increase, it functionality has been integrated into today's business community, with each new business incorporating the required it-related investments, so that overall it investment will inevitably increase. The difference between this and today's situation is that it is not just a backend support function, but a prerequisite for customer orientation. It will become a partner for the business unit to achieve its long-term goals and will not be vilified against each other after a project has ended.

It reorganization. The other side of the business is like a commercial operation. Cost transparency will be required. The rise of public cloud providers provides a benchmark for internal it comparisons. Not being able to provide similar transparency would be a suicide.

As cost transparency increases, and the cost of it deployment is determined by a number of factors (including privacy, compliance, application bandwidth/latency requirements, and so on), this helps determine the decision method for selecting internal or external applications for deployment. Assuming that the application defaults to internal deployment, the idea of an external deployment is obsolete when it is created. Wise CIOs will begin to realize that their role is to manage the infrastructure, not the assets. The less sensible CIOs will find themselves ignored and bypassed by user organizations.

Along this line of thinking, companies will find their biggest challenge on the road to the post-cloud era it is legacy systems. These systems are a huge drag that will seriously impact the needs of the IT enterprise with the enterprise users who want to find partners in the development of new IT products. For the post-cloud era, there will be no additional spending to manage legacy applications, even the lowest additional investment. These application maintenance costs far outweigh today's product prices. Of course, today's businesses are trying to find ways to reduce the overhead of legacy systems, such as outsourcing e-mail systems to external vendors. But it companies must be more active, otherwise they will have little enough budget to do what is necessary. Each CIO needs to evaluate existing systems and come up with a cost-cutting solution, whether through SaaS or cheaper outsourcing.

Using PAAs. Too many people simply understand that cloud computing is the use of virtual machines. The industry's rapid growth is much more than that. When http://www.aliyun.com/zixun/aggregation/13521.html > Application developers deploy applications to scalability and resilient architectures, they are wasting their time. In infrastructure processing, application developers should focus on the functionality of the business, not the pipeline. The approach is through a platform, a service (PaaS). In the post-cloud era IT companies will rely heavily on PAAs, using internal or external platforms to manage basic functionality and infrastructure. Too much overhead at this level is worthless, so finding the most efficient and cost-effective way to manage them is to provide an environment that simplifies the production of application developers.

Shortage of application developers. The paradox of Jevon means exploding demand for it. Especially for application developers. These developers know how to build business products, can integrate a variety of applications into a new product, can skillfully implement the call external APIs and services to meet high demand. Paradoxically, even with the emergence of PAAs, the demand for application developers continues to grow. Higher productivity means lower unit costs, which leads to increased demand.

But this is not to say any application development. Nor is it simple to understand a development language or framework. The development of this application is similar to that of a general contractor, which requires the ability to assemble a set of internal and external components and services. As the IT investment changes to the application direction, the post cloud era of development talent will be more scarce, so as a cloud CIO, you need to start thinking about your strategy in order to win more and better people.

I hope that my article will receive your comments. I believe some of them will continue to say: "Cloud computing is really good, but it is now just one of the options for our business." "These people are unable to break their past mind-set and have no insight into the changing world," he said. Of course, someone will say: "We have been using cloud services, but only for time-sharing systems and mainframe." "These people have not yet figured out similar concepts, and when they are executed in different situations, they are completely different situations." Finally, someone might say, "cloud computing is pretty good, and we're deploying cloud computing by building a predefined virtual machine to provide a directory of services." "These people can't understand how quickly the world goes beyond the deployment of applications to virtual machines," he said.
