Cloud computing is now widely used and developed. What is certain is that the future competition of cloud computing will become more intense. In fact, the term “cloud†is appropriate because, like clouds in the sky, the technology of cloud computing is constantly changing and changing, and will reshape its shape. The trend and trend of guiding the development of cloud computing is the demand of enterprises, because enterprises understand what it means to accept cloud computing for market competition.
The future of cloud computing will be a hybrid cloud
A survey conducted by research firm IDG Research Services earlier this year found that nearly 40% of companies using a public cloud have moved some of their workload back to the on-premises data center, mainly because Security and cost issues.
The trend is that companies are more cautious. They are realizing that sometimes the difficulty is the heavy workload of cloud computing, and they are more sensible about adopting cloud computing.
But many companies are still moving their business to the cloud. The cloud-first corporate strategy is significantly enhanced. HypsRamp, a hybrid cloud IT operations management provider, conducted a poll of IT leaders in large enterprises (more than 500 employees) and found that its public cloud services accounted for a larger share of IT budgets.
More than half of the respondents said they have used the public cloud for more than three years, but only 29% said their cloud adoption level is “mature,†while “development†is 50% and “emerging†is 21%. The report pointed out that "the application of cloud computing has a certain room for growth and will continue to grow."
The question raised by the shape and form of the future development of cloud computing is what form cloud computing will take in the future. The survey found that three-quarters of respondents said they want to work with different cloud computing providers. Meet their business needs. For this reason, a new vocabulary enters people's sights after the emergence of public, private and hybrid clouds: cloudy.
There are two ways to use cloudy, so companies need to understand this. One approach is to define two or three cloud types together, such as a mix of public and private clouds. Of course, this is a hybrid cloud. Another way to use cloudy is to use cloud services from multiple cloud providers. A company may work with Amazon, Microsoft, and another smaller vendor, perhaps just to store data.
Avoa is a CIO strategic consultant, and TIm Crawford, a senior consultant for data center and cloud computing issues, says people need a variety of different services to meet a variety of different mechanisms, so by default a hybrid cloud or Cloudy practice.
“There is no single cloud service type that can meet all the needs of the enterprise. The reality is that companies will have to use their combination. This is not an individual case. It is what most companies are doing,†Crawford said.
Crawford said that it is now beginning to see that this momentum is growing. "Many people think that the application of cloud computing will eventually be a public cloud, but I think this is not true, because in some applications, public cloud is not a viable solution for enterprises," he said.
Steve Tack, senior vice president of products for cloud computing application performance monitoring provider Dynatrace, said that the consensus with customers such as large enterprises and independent software vendors (ISVs) is that hybrid cloud will be the direction of future development, "no matter what people call it The hybrid cloud is still cloudy."
There are two drivers for cloud computing migration, he said, and people are concerned about the density of containers and microservices architectures and the speed of time to market. There are many benefits to using the microservice approach, such as deployment speed and component decoupling to make them easier to deploy and update.
But he also mentioned that companies have moved from a waterfall-style approach to a more agile continuous integration/delivery approach. He said that companies usually release a major version every six months. They speed up the update by combining them. One way is to adopt automation. Organizations that use automated testing and performance analysis can free developers from testing and analytics and focus on real-world development. Automation also provides visibility and insight into the usage and customer experience.
“By getting a feedback loop and adopting a continuous deployment approach, companies can accelerate their application lifecycle and accelerate deployment,†he said. “When companies combine cloud native applications, containers, automation, agility and DevOps, they Will provide composite value for the company."
The limitations of the public cloud, Task, suggest that most of the new cloud computing investments are driven by the demands of new investments and new initiatives, but he also sees existing data center applications "upgrading and moving" into the cloud. The number has increased.
"The original applications were built around competitive advantage, and the applications that migrated to the cloud were developed around cost. They are now supported by the enterprise," he said.
However, "boosting and transferring" may not be a good idea. Some surveys have found that companies are quickly returning to their on-premises data centers after migrating some applications to the cloud. Crawford said that this is not because the use of public clouds is more expensive, but the cost of running a business in a public cloud is more expensive.
“Public clouds can use these programs four times more often than traditional data centers. This is because the original application (assuming it is not rewritten or re-architected) is used at the peak of the redundant architecture, and Running around the clock. Public clouds don't run this way. If companies use designs that are more suitable for public clouds, then the cost will be lower," he said.
So why do many companies make this mistake? This is because they don't understand cloud computing. “People have a lot of ideas about cloud computing. How do companies determine what is true and what is not? Many analysts even judge from the latest press releases,†he said.
Therefore, migrating data center applications to the cloud will not be a major trend in the future as they work differently. Crawford also believes that network latency may also be detrimental to the adoption of public clouds, while internal/private clouds such as IoT and edge services may be more widely used. "Because the speed of the network connection is still a limiting factor," he said.
New future cloud computing model?
Both Task and Crawford said that they have not seen the emergence of a new cloud computing model because they are not needed. The current cloud computing type is sufficient.
"Most of the companies in the real world are using hybrid clouds," Crawford said. "It's possible that the enterprise's data center is running SaaS using a public cloud. It can also be run separately, depending on whether it is really hybrid." Say.
Crawford said that there are still many companies that use container technology, which is serverless computing through the public cloud. "Serverless computing" is a bit of a misnomer because it actually requires the server to run instead of allocating virtual machines or containers and deploying code to them. The development team just uploads its application, which is called a function. Because it performs a single function, then the vendor (AWS or other) executes the function and closes, and it stops when the process completes.
It solves one of the biggest problems in cloud computing: people can easily forget to shut down a virtual machine when completing a task. Developers and other users forget to shut down their virtual instances and keep them running, and if the virtual machine is always running, the cloud provider's billing program is always running. This is why companies have high billing fees after adopting cloud computing.
With serverless computing, businesses don't start virtual machines, so there's no need to worry about shutting them down. It creates an instance to execute the code, which is a simple single-function application and then closes when the task is completed.
"It allows people to design, build, and run applications and services, and abstracts them from the process of processing hardware and managing servers, and pays only for the work they do," he said.
“I still think there is a lot of space for large-scale migration and containerization on the market, and it also has a lot of interest in serverless computing, and the impact on the overall structure will be quite large,†he added.
