The traditional IT architecture is no longer suitable for today's digital economy rapid development. Technical Consultant Declan Morris expressed : "Customers not only expect zero downtime, and require the application anywhere in the world with a consistent performance." He also predicted, followed by non-server computing and functions as a service (FaaS) of the world .
Due to be used to build a limited number of personnel management and maintenance of next-generation digital systems, coupled with constrained computing IoT devices, now people have to re-consider the appropriate computing platform. Cisco said that by 2022, we will have one trillion networked sensors, and in 20 years will be as much as 45 trillion. If it is desired to manage all of these connected devices, it is out of necessity, we will have to adopt FaaS. In no server world, it is much easier to simply call a function or set of functions to get results. In addition, no-cost server computing also lower than the cost of server-based, server-free, pay only for performing this function.
So how developments in today's server without it? O'Reilly consulting firm of more than 1,500 respondents from different regions, industries and companies to do a survey , let's take a look at the specific content of the survey.
Organization of about 40% of the respondents where the use of non-server. Of these, more than 50 percent of respondents employed within one to three years, while 15% of respondents in three years ago on the use of non-server. As of November this year, Amazon's AWS Lambda is only 5 years old, and therefore, contrast, owning any organization using more than three years of experience are considered very early adopters.
In addition, more than two-thirds of respondents believe their organization at least "most successful" of non-server uses. The success of the overall pattern shows that no server has become a substantive and viable infrastructure choice. Adopted sooner, the more experienced organization, the higher the success rate of use of non-server. Because no server needs time and experience to solve tool-free server caused by the data protection and operational challenges.
No server benefits are also evident. "Reduce costs" in the first place. Followed by "automatically expand as needed," meaning that organizations can selectively deploy serverless, average or maximum amount without having to use the program, but may be extended to the current usage, this extension eliminates the random and unexpected traffic peaks or seasonal troubled large flow resistance. In third place are the benefits of "no server maintenance", when the repair, protection and management details such as the responsibility of the non-server providers, software engineers can make time to focus on a wider range of tasks.
"Reducing project preparation time" and "reduce development costs." For more than three years, the Company has no server is more important benefits. Of course, this also shows that no server needs to spend a lot of time to begin to see significant cost advantage.
No problems related to the use of the remaining servers, "staff training" ranked first, "vendor lock-in" and "integration / test more difficult," are two other problems.
DevOps and no server seems natural match, so the DevOps team regarded as the first non-management server implementation would not be surprising. Container service deployment on non-server architecture and uses Kubernetes orchestrating these services in line with existing DeOps practice.
From the cloud market, Amazon delivery earlier to keep a certain dominance, Microsoft and Google are constantly compete and expand difference as far as possible.
In general, no server is being increasingly widely used, it brings a lot of obvious benefits, there are some problems to be solved. Next, the demand for non-servers will continue to grow, which is another valuable infrastructure choice for many organizations. Regardless of the particular technology or programming language, no server can handle a variety of tasks, and over time, entry is getting easier.
