This article mainly explains "what is the difference between IaaS/PaaS/SaaS". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what is the difference between IaaS/PaaS/SaaS".

The difference between IaaS/PaaS/SaaS

Let's start with a simple example to distinguish between these concepts. Take my lunch "cooking rice" as an example (for example, picking up people's wisdom, based on my own understanding, and citing another example):

Whether I cook boiled rice myself or others help me cook boiled rice, we all need the following raw materials:

Rice, ingredients, dishes (meat, vegetables, etc.), induction cooker, pot, electricity, table, beverage (essential for cooking rice)

Then, according to the situation of people who cook rice, it can be divided into the following situations:

On-Premises: responsible for all processes, including the purchase and production of raw materials, etc.

IaaS: buy the finished product (rice, seasoning and dishes have been matched) and bring home your own kitchen utensils to make

PaaS: just order takeout, just take out your own table and drinks.

SaaS: go directly to the store to eat. All the food is provided by the store.

Definition of IaaS/PaaS/SaaS

Let's go back and look at the definition of these words (from the encyclopedia):

IaaS

Infrastructure as a Service, or Infrastructure as a Service. It refers to a service mode that provides IT infrastructure as a service through the network and charges according to the actual usage or occupancy of resources by users.

PaaS

Platform as a Service, which provides a software deployment platform, abstracts the hardware and operating system details and can be extended seamlessly. Developers only need to pay attention to their own business logic, not the underlying layer. That is, PaaS provides an environment for generating, testing, and deploying software applications.

SaaS

Software as a Service, Software as a Service, that is, provides software services through the network.

The current bottleneck of SaaS

Because of the development of cloud computing, these concepts are deeply rooted in the hearts of the people. Different enterprises will adopt different business models out of different considerations, and SaaS is not only suitable for small and medium-sized enterprises, but also enterprises of all sizes can profit from SaaS. However, due to technological limitations and market maturity, SaaS will face the following dilemmas:

Technical aspects:

At present, the customization technology of SaaS software personalization is not yet mature. The services provided by SaaS are destined to meet the customized needs of customers on the basis of a general SaaS platform. The customization service of traditional software is completed in the software development stage, so the requirement of customization ability is not high. However, SaaS needs to be updated and customized according to the changes in requirements during the use of the software, and can not affect the use of other users when customized. In addition, the operation of SaaS must be simple and save customers' learning costs. The above two points make the technical development of SaaS more complex. The experience of traditional software can not be pushed away in SaaS.

Market system

At present, the system of SaaS in the market is still quite chaotic. In the current SaaS market, SaaS service providers focus on providing services for large customers, while ignoring small and medium-sized customers. Moreover, because of the profit model of SaaS, although some SaaS service providers have a large number of high-quality customers, they do not accelerate the promotion of SaaS. The second is that the domestic demand for SaaS has not been able to land. This situation can refer to an answer from Zhihu: why is Chinese software not as developed as abroad?

Data security

In addition, the domestic system for software has not been perfect. The problems of data storage and data security in the cloud are also the main factors that customers have doubts about SaaS services. Because of the characteristics of SaaS services, the security of data needs to be a kind of dynamic security not only to ensure that the data is not lost, but also to ensure that users can flexibly adjust when the security requirements caused by business increase or decrease. At the same time, because the platform is shared by multi-tenants, the interaction of data and information is complex, and the requirement of data authority is very high. For network security, the stability of the Internet poses a great challenge to the application of SaaS. The uncertainty of enterprise intranet and Internet connection is too high, no matter what factors cause the fluctuation of network stability will affect the use of software, and even cause the loss of user data.
