The key ： Cloud computing , Concept , Cloud native

Hello everyone , Today I share the following cloud computing concepts , Recently popular architecture , Cloud native architecture , Can not do without the blessing of cloud computing , Therefore, it is urgent to understand the concept of cloud computing , I am a little weeks , If you think the article is well written , Remember that Sanlian supports poor bloggers

What is Cloud Computing ？

Simple understanding , Cloud computing is the provision of computing services （ Including servers , Storage , database , The Internet , Software and so on ）, Instead of purchasing by renting services , In this way, enterprises do not need to spend a lot of money to buy servers , Data storage and other equipment , You can get computing power through the Internet , And pay according to the actual use , To help reduce operating costs , Make the infrastructure operate more effectively , And can adjust the use of services according to the change of business needs , The conclusion is ： Scalable 、 flexible 、 intelligence

Moving to the cloud

Enterprises choose to migrate to the cloud , Then its infrastructure will no longer be deployed internally , Instead, move to a data center maintained by a cloud computing provider , Cloud computing can provide superior agility , Scalability and flexibility , Enterprises focus on more strategic and important work , Instead of spending energy and time buying and maintaining system resources , Enterprises pay on demand , You can quickly obtain and access the computing resources you need

Types of cloud computing

Cloud computing can be simply divided into three types ： Public cloud , Private cloud , A hybrid cloud , Different kinds of cloud have different levels of security

Public cloud

All the computing infrastructure of the public cloud is deployed inside the cloud service provider , Customers don't have to worry about infrastructure and maintenance , You can buy and use computing power on demand

Private cloud

Private cloud , It's easy to understand , It can be deployed within the enterprise , It can also be deployed in the data center of the cloud service provider , It can provide the highest level of security and control

A hybrid cloud

seeing the name of a thing one thinks of its function , It is a mixture of public cloud and private cloud , In real environment , Many enterprises tend to trust their key businesses in their own enterprises , To obtain higher security and control capability , The secondary storage will be on the server of the cloud provider , Public private combination , It's called a hybrid cloud

Cloud service type ：IaaS、PaaS、 No servers and SaaS

Most cloud computing services fall into four categories ： Infrastructure as a service (IaaS)、 Platform as a service (PaaS)、 No servers and software as a service (SaaS).

Infrastructure as a service (IaaS)

The most basic category of cloud computing services .
Use IaaS when , You rent from a service provider on a pay as you go basis IT infrastructure , Like servers and virtual machines (VM)、 Storage space 、 Networks and operating systems .

Platform as a service (PaaS)

Platform as a service (PaaS) Cloud computing services , They can provide development on demand 、 test 、 The environment needed to deliver and manage software applications .
PaaS Designed to make it easier for developers to create Web Or mobile apps , You don't have to think about the servers that are necessary for development 、 Storage space 、 Network and database infrastructure to set up or manage .

Serverless computation

Use PaaS Overlap , Server free computing focuses on building application functions , Customers don't have to spend time managing servers and infrastructure .
Cloud providers can handle settings for you 、 Capacity planning and server management . Server free architecture is highly scalable and event driven , And use resources only when specific functions or events occur .

Software as a service (SaaS)

Software as a service (SaaS) Is a way to deliver software applications over the Internet , Usually based on subscription and provided on demand .
Use SaaS when , Cloud providers host and manage software applications and infrastructure , And responsible for software upgrades and security repairs and other maintenance work , Users connect to applications via the Internet .

Cloud computing instance

You roam the world of the Internet , Maybe cloud computing is being used at this moment , From small start-ups to large enterprises , You can always see the application of cloud computing services , Why is cloud computing so popular ？

Create cloud native applications based on cloud computing services

Complete data analysis based on cloud computing services

Embedded intelligence based on cloud computing services

Cloud based service storage , Backup and restore data

Deliver software on demand based on cloud extreme Services （ Software as a service ）

At the end

Read here , You must have a basic understanding of Cloud Computing , The author's ability is limited , If the article is wrong , Please also point out that , Last , Cloud computing is very hot , Now cloud based native cloud is also very hot , It's not hard to see. , The new architecture direction is waiting for you in the near future , however , I hope you can lay a good foundation , therefore , Come on! , juvenile , Don't forget , Sanlian supports poor bloggers , I am a little weeks , Looking forward to your attention .
