This article mainly introduces "what is suitable for large and medium-sized hotel group PMS". In daily operation, I believe many people have doubts about what is suitable for large and medium-sized hotel group PMS. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the question of "what is suitable for large and medium-sized hotel group PMS"! Next, please follow the editor to study!

Recently, there have been two major Internet security incidents, one is that the optical fiber of Alipay was dug off on May 27, and the other is the downtime of Ctrip on May 28. Alipay spent two hours switching traffic to other computer rooms and nodes, while Ctrip users waited 12 hours. Are Internet companies, why the recovery speed of the two is so different? Because this is a comprehensive test and contest of technology, architecture and operation and maintenance. These two events make the importance of the website technical security architecture fully reflected, but we usually do not pay much attention to it.

In the field of hotel information management, the technical architecture of PMS is also not highly valued. For hotel chains with hundreds or thousands of stores, the stability and security of PMS will affect the daily turnover of millions or tens of millions, the reservation and check-in experience of tens of thousands of people every day, and the loyalty of tens of millions of members. Therefore, large and medium-sized hotel chains have to attach great importance to the technology, architecture, operation and maintenance of PMS.

At present, there are many large-scale hotel chains to develop their own systems, such as Pentao, Yibai, Vienna, Urban 118, Fuyi Fashion, City convenience, each with dozens of development teams and hundreds of servers, not to mention spending more money, the IT department is busier than using third-party software, and feels more tired, and many aspects are not very recognized. Specializing in the technology industry, after all, the hotel is not dry Internet, dry IT, resulting in the pattern, structure, openness is not fully considered, security and stability is not very satisfactory.

The author has been engaged in the development, management and architecture of large-scale systems with high concurrency and high availability such as banking and telecommunications, as well as Internet SAAS and middleware for 15 years, especially the experience in the successful development, deployment, operation and maintenance of cloud PMSSAAS+PAAS platform used by more than 10, 000 hotel users.

So, what should be the structure and characteristics of PMS chosen by large and medium-sized groups?

First, flexible and open architecture, the first choice of SAAS+PAAS, must be based on the SAAS+PAAS architecture.

SaaS is the abbreviation of Software-as-a-Service (Software as a Service). With the development of Internet technology and the maturity of application software, a completely innovative software application model has sprung up in the 21st century. It has a similar meaning to "on-demandsoftware" (on-demand software), theapplicationservice provider (ASP (application service provider) and hosted software (managed software). It is a mode of providing software through Internet. Manufacturers deploy the application software on their own servers. According to their actual needs, customers can order the required application software services from the manufacturers through the Internet, pay the fees to the manufacturers according to the number and time of the ordered services, and obtain the services provided by the manufacturers through the Internet. Instead of buying software, users rent Web-based software from providers to manage business activities without maintaining the software. Service providers have full authority to manage and maintain the software.

ASP model is a popular model before SAAS, which is equivalent to manufacturers buying servers, developing applications, and deploying a set of applications to a hotel brand separately. It seems that ASP is also based on Internet, but it may be a web system for small chain hotels or individual hotels. In fact, the factory's commercial technical requirements are low, and the considerations of security, high availability and scalability are far worse than SAAS.

For a real SAASPMS, supporting 100 stores is a hurdle, supporting 100 chain brands is another hurdle, and supporting 10000 stores is a higher hurdle.

PAAS makes the SAASPMS system flexible and pluggable, and can be easily connected to other systems, such as HR, CRM, OA and other systems, so that the front desk, sales, finance and store manager of the hotel do not need to upgrade in the PMS system, have an account password and unwittingly enjoy the functions and services of HR, OA and other systems. A set of SAAS supports PAAS, which eliminates a lot of customization troubles for SAAS manufacturers and gives independent modules to better manufacturers; for hotels with development strength, they can define and expand their functions. For third-party system developers, such as HR and OA developers, you can call the API interface of SAAS manufacturers to develop new integrated applications, such as obtaining sales development membership data, calculating salesperson performance, automatically correcting salaries in the HR system, and displaying each salesperson's performance salary, full salary, tax payment, actual payment function, and so on, in a page of PMS.

Second, high security must be guaranteed.

No matter how many features, no matter how good the user experience, for PMS, security is the foundation, the leakage of guest data is a big deal, not only guest complaints, but also brand damage. Like the previous data leaks of a listed hotel chain, it is a disaster for hotels and guests. For listed hotel chains, the stock will fall for several days in a row, and it is possible to reduce the market value by hundreds of millions, which shows how important safety is.

Choose WindowsorLinux? Linux/Unix servers are used by 80% of the world's websites, and almost all Linux/Unix servers are used by BAT, JD.com, Telecom and banks. Linux/Unix is one level more secure than Windows as a server operating system.

Open source software, the LAMP architecture used by 70% of the world's websites. LAMP architecture refers to a group of Linux+Apache+Mysql/MariaDB+Perl/PHP/Python open source software commonly used to build dynamic websites or servers, which are independent programs themselves, but because they are often used together, they have a higher and higher degree of compatibility and form a powerful Web application platform. Later, due to the good mechanism of J2EE (JAVA), it provides another important choice for building large-scale websites with high availability, high scalability, supporting heterogeneous environment and distributed. A large number of giant websites, such as Taobao and JD.com, are built with J2EE (JAVA).

Without piracy, the use of piracy will often receive letters from lawyers, if it is made public, it will have a great impact on reputation and brand, and the impact on listed companies will be even greater. In fact, a large number of open source software is enough to build the operating environment and components needed for the development of various systems (including PMS, CRS, website, Wechat application, APP, OA, HR) used by the whole group hotel chain.

Third, must have high availability and high scalability

To achieve 99.9% high availability, that is, only 8 hours a year are unavailable. For example, Ctrip had a 12-hour downtime at the end of May, which greatly reduced the high availability of Ctrip.

The general law of the development and evolution of the SAAS system is that it has just changed from the system based on the Cramp S architecture to SAAS. During the first half of the year, the high availability can only reach 95% at most, and the system will go down at least once a week during the first half of the year. In the second half of the year, there are continuous access to seed users. When seed users reach 200 different brands, the product has great adaptability and versatility. The system will go down every two to four weeks, and the high availability can reach 98-99%. After the third and fourth months, with the exponential increase in the number of users, the system performance and bottlenecks are constantly exposed and optimized, and the system goes down every two months, and the high availability can reach 99.9%. The recovery speed after downtime is also very different at each stage, and it will take several hours-one day in the first six months or a year. With the improvement of the architecture, the familiarity of the operation and maintenance team with the diagnosis of various problems, the familiarity with the tuning of various deployment components, and the improvement of the operation and maintenance system, it can be shortened to a few minutes.

In short, without two years and 10, 000 users, a SAASPMS system cannot mature.

To achieve 99.9% high availability, you must:

1) before the launch of the new version, rigorous functional testing and performance testing should be done, and automated unit testing and functional testing should be carried out to ensure that the previous stable function will not be destroyed.

2) grasp the quality, timing and grayscale of the launch version

3) routing server, application server, cache server, message middleware server and database server should be deployed separately, load balancing and automatic health check to prevent single point of failure.

4) disaster recovery in different places. When there is a problem with the server or network equipment of a computer room node, or when the optical fiber is dug out, switch to another computer room node automatically or after data verification, just like Alipay.

5) High scalability ensures that hotels do not need to panic when adding stores, sudden traffic during holidays and promotions, because ten servers can be purchased and opened in a few minutes, and the environment can be prepared and launched in one hour to handle massive traffic.

Fourth, strong operation and maintenance ability is also critical.

The operation and maintenance of the PMS system of large and medium-sized chain hotels must have strict operation and maintenance system, 7-24 real-time monitoring and health check, detection and prevention in advance, disaster prevention and exercise, database crash, attack, domain name problems and other emergencies.

From the architecture knowledge introduced in this article, there is still a threshold for PMS, especially cloud computing PMS, which is not a technical team of more than a dozen people and cannot be built in a year or two.

The Internet is flat, and Internet technology and mobile Internet technology are developing rapidly and changing rapidly, so it is difficult to achieve a good and competitive structure.

At this point, the study on "what is suitable for large and medium-sized hotel group PMS" is over. I hope to be able to solve your doubts.
