What are the meanings and application scenarios of the three giants of cloud computing: IAAs, PAAS and SaaS?

Hello , This is the network technology alliance station .

With the increasing popularity of cloud environment , More and more enterprises are getting rid of local  IT  Solution , And gradually rely on the cloud environment , When selecting cloud services , We often see IaaS、PaaS、SaaS Etc , So what do these three terms mean ？ How to choose ？ What's the difference between the three ？

In this article, Ruige uses concise and comprehensive language , Take you to explore IaaS、PaaS、SaaS.

Let's go straight to ！

What is Cloud Computing ？

In explanation IaaS、PaaS、SaaS front , We need to learn about cloud computing first .

Cloud computing concepts

Cloud computing provides different services through the Internet , Including tools and Applications , Like data storage 、 The server 、 database 、 Networks and software , Cloud based storage does not store files on proprietary hard drives or local storage devices , Instead, you can save them to a remote database , As long as the device can access the network , Then you can access the data and run its software program .

Cloud computing is so named , Because the information being accessed is found remotely in the cloud or virtual space , Companies that provide cloud services enable users to store files and applications on remote servers , And then through  Internet  Access all data , This means that users do not need to be in a specific location to access it , This allows users to work remotely .

The advantages of Cloud Computing

• reliable
  ： Cloud providers can provide 7X24 Operation guarantee of , And usually redundancy can be done , Strong reliability .

• flexible
  ： The cloud environment is very flexible to use , For example, there is not enough memory , Then expand the memory online , Insufficient bandwidth , Then add bandwidth online , All operations are smooth and simple , Very flexible .

• Cost savings
  ： Cloud environment means that there is no cost of hardware or facilities ,IT  The time for personnel to maintain and upgrade the system is also greatly shortened .

• Keep up to date
  ： Cloud computing vendors always have the latest version of the platform 、 Databases and software applications . Besides , You can also use machine learning  (ML)、 Artificial intelligence  (AI)、 The Internet of things  (IoT)  And so on .

Types of cloud computing services

There are generally three types of cloud computing services ：

Then we will introduce these three types in detail .

IaaS

• English full name ：
  Infrastructure as a service

• Chinese name ：
  Infrastructure as a service

IaaS, Suppliers provide users with access to storage 、 Access to computing resources such as networks and servers , Companies use their own platforms and applications in the infrastructure of service providers .

IaaS Use scenarios

• disaster recovery

• Automatic expansion and cluster management

• High performance computing  (HPC)  And big data analysis

Can provide IaaS The manufacturer of

• Alibaba cloud

• Tencent cloud

• Hua Wei Yun

• AWS

• EC2

• Microsoft Azure

• GCE

PaaS

• English full name ：
  Platform as a service

• Chinese name ：
  Platform as a service

PaaS, Suppliers provide customers with a complete application development environment , Allow them to develop and manage applications , Without building a time-consuming development environment .

Use  PaaS  Users of can also access various resources in the application stack , For example, middleware 、 programing language 、 Operating systems and databases .

PaaS  The biggest benefit is that

There's no need to make wheels again

, Companies can use  API  Quickly assemble a collection of third-party solutions , Development teams can pay monthly fees and use resources to build and deploy applications , This is faster than building from scratch .

In short ,PaaS  Allow companies to focus on their core strengths and agile software development , To provide unexpected results .

PaaS Use scenarios

• Full cycle automation and composable Services

• Realize rapid application development

PaaS Example

• Google App Engine

• Red hat  OpenShift

• Heroku

• Apprenda

SaaS

• English full name ：
  Software as a service

• Chinese name ：
  Software as a service

SaaS Also known as cloud application services , Is the most comprehensive form of cloud computing services , adopt  Web  The browser provides the entire application managed by the provider ,SaaS  It is very suitable for small companies or start-ups that do not have the ability to develop their own software applications .

adopt  Internet  Any application accessed is  SaaS, E-mail service 、 Website builder 、CRM  System 、 Video call service and so on .

summary

Cloud computing enables companies to access many services through the Internet , Services fall into three categories ：IaaS（ Infrastructure as a service ）、PaaS（ Platform as a service ） and  SaaS（ Software as a service ）.
