The indissoluble bond between popular script killing and SaaS

In recent years, "Script Killing" is an entertainment project that takes the script as the core, and players play different roles to reason about the case and find out the true murderer. It has spread rapidly among young people, and has quietly formed an emerging market with a market size of over 10 billion. The industry has attracted a large number of gold prospectors. In the Internet era, a small program called "Script Killing SaaS" has also emerged in response to the needs of players to kill online scripts and the requirements of stores to maintain users. In the mini program, you can provide script catalog, organization, membership management, employee management and other functions for the script killer. Thousands of WeChat mini-programs can be developed and maintained with only a few hundred yuan in cloud development costs per month. As the name suggests, the program uses SaaS cloud technology. This technical profile is easy to use for entrepreneurs and also provides consumers with more choices and convenience. Of course, the point we are going to talk about today is not to kill scripts, but to talk about SaaS.

What is SaaS

SaaS (software as a service) is currently one of the most popular forms of cloud computing. It goes hand in hand with IaaS (Infrastructure as a Service) and PaaS (Platform as a Service). SaaS is a cloud-based software delivery model. In this model, cloud service providers develop, provide, and maintain cloud application software, keep the software automatically updated, and provide services to their customers on an on-demand basis through the Internet. The public cloud provider manages all hardware and traditional software, including middleware, application software and its security. Therefore, SaaS customers can significantly reduce costs, facilitate the maintenance of local systems and software, deploy and expand faster, upgrade business solutions, and more accurately predict required costs and expenses.

The history of SaaS can be traced back to the 1960s, when a software delivery system called time-sharing appeared. "Dumb terminal"). With the advent of the Internet in the 1990s, providers began to host software and provide it to customers via the Internet. However, this pioneer of SaaS, called the Application Service Provider (ASP) model, has serious limitations. For example, each customer needs its own software version, which means that some software must be installed on the user's computer, which is expensive and time-consuming to configure.

The first SaaS solution appeared in the late 1990s, when the term SaaS was first coined. This new model provides higher efficiency than the ASP model. Because of its so-called multi-tenant architecture, a single instance of an application can provide services to multiple users or even customers, eliminating the need to install software locally. It provides a way to collect, aggregate, and centralize valuable application data. Since 2000, SaaS has significantly evolved from the first generation of isolated solutions to modern SaaS suites that can achieve high visibility throughout the business and are widely used in artificial intelligence, machine learning, the Internet of Things, and regional Multiple technologies such as blockchain, augmented reality and virtual reality.

Advantages and risks of the SaaS model

The biggest advantage of SaaS is that it entrusts all infrastructure and application management to the SaaS provider. All the user has to do is create an account, pay the fee and start using the app. The supplier is responsible for everything else, from maintaining server hardware and software to managing user access and security, storing and managing data, implementing upgrades and patches, and so on. Other advantages include:

• Reduce costs: No additional hardware and middleware are required, reducing installation and implementation costs. Subscribe to products on demand and pay flexibly.
• Rapid deployment: No hardware is required, so it can be deployed quickly. Users can access applications faster, thereby increasing productivity and employee satisfaction.
• Easy to expand: Provides a high degree of vertical scalability, allowing customers to choose to access more or fewer services or functions on demand.
• Accessibility and durability: Since SaaS providers deliver applications over the Internet, users can access it from any Internet-enabled device and location.
• While being convenient to use, SaaS also brings some potential risks and challenges, because companies must rely on external vendors to provide software, keep the software running normally, track and report accurate billing, and rely on vendors to provide secure corporate data. environment. This leads to some hidden dangers:

When providers encounter service interruptions, make unnecessary changes to service products, or encounter security vulnerabilities, these will have a profound impact on the SaaS products used by customers. In order to solve these problems, customers should understand the SLA of their SaaS provider and ensure that they are implemented in place. In addition, customers lose control of the service version. If the provider updates a new version of the application, it will push it to all customers, regardless of whether the customer really needs to update the version. The most complicated is to change the supplier, the customer must migrate a very large amount of data. In addition, some vendors use proprietary technologies and data types, which makes the transmission of customer data between different cloud providers more cumbersome.

In addition to the above issues, cloud security is also considered to be one of the most significant challenges for SaaS applications.

SaaS vs PaaS vs IaaS

Now that I talked about SaaS, of course I have to mention its other two brothers-IaaS and PaaS.

IaaS stands for Infrastructure as a Service. It is an on-demand access to cloud computing infrastructure (servers, storage, and network resources). Customers can configure and use these infrastructures as if they were local hardware. The difference is that cloud service providers host, manage, and maintain hardware and computing resources in their own data centers. IaaS customers use the hardware through the Internet connection and pay for the use by subscription or on-demand.

PaaS stands for platform as a service, which provides a cloud-based platform for developing, running, and managing applications. The cloud service provider hosts, manages and maintains all hardware and software included in the platform, including servers (for development, testing and deployment), operating system (OS) software, storage, networks, databases, middleware, frameworks, development tools , And related services such as security, operating system and software upgrades, and backups. Users access PaaS through a graphical user interface (GUI), where development or DevOps teams can collaborate on all tasks in the entire application lifecycle, including coding, integration, testing, delivery, deployment, and feedback.

SaaS, PaaS, and IaaS are not mutually exclusive, but together constitute the most basic service layer of cloud computing-public cloud. The three models supplement the completeness of the product in different aspects. Among them, SaaS products are complete and fully managed applications. IaaS is mainly about outsourcing data center resources. PaaS provides development platforms and other tools hosted by the provider's data center.

At the same time, these three kinds of "as-a-service" have the characteristics of low cost, which allows customers to enjoy dedicated IT services without assuming any equipment or configuration management personnel. This facilitates customers to choose different solutions according to their needs, which is flexible and convenient.

As mentioned at the beginning of the article, "Script to kill SaaS" exists in the form of a small program, which can be used simply by accessing it. The SaaS solution does not require users to bear all kinds of unnecessary technical worries and the influence of uncertain factors such as design and network. It can simply and quickly promote the access to cloud services in various industries and accelerate industry innovation and growth. It is undoubtedly the most popular service model La~
