in general, we develop Web application, you need to IT OPS Personnel Preparation Windows OS or Linux OS of the Web Server , install the appropriate Web components, such as IIS, Tomcat and so on. The developer then deploys the appropriate code to the Web Server and configures it.

forITOPS Personnel,Web Serveris aIaaS,ITOPS personnel need maintenanceWeb Serveroperating system and other content. And for developers,Web Serveris aPaaS, developers only need to maintainWEB Applicationcan be. OPS people care about the operating systemOSlevel of something that developer relations own code whether there 'sBugcan be.

So, Azure Web Apps What is it, Azure Web App provides a PaaS service. Simply deploy the developer's code directly to Azure Web Appswithout operating system level management, directly reducing the cost of management. Implemented, we are now talking about the operation of systematization, or no operating system layer.

first, it is important to note that: Azure Web Apps supported development languages include: . NET, Java, Php,python

Basically covers all major development languages.

Second, Azure Web App what can be used to do?

It offers four levels of service, of course, and the charges for each tier are different:

1. 1. Free (free)

(1) The client's computing resources are shared with other users

(2) every day there is only - minutes of CPU Calculation Time

(3) The maximum storage size that can be used is 1GB

(4) scale-out functionality is not supported

(5) No SLA Protection of

1. 2. shared (Shared)

(1) The client's computing resources are shared with other users

(2) The maximum storage size that can be used is 1GB

(3) every day there is only - minutes of CPU Calculation Time

(4) Scale -out capability supported, with horizontal support up to 6 a shared instance

(5) No SLA Protection of

1. 3. Basic (Basic)

(1) customer's computing resources are exclusive

(2) You can create an unlimited number of types Basic of the Azure Web Apps

(3) The maximum storage size that can be used is 10GB

(4) Scale -out capability supported, with horizontal support up to 3 an exclusive example

(5) Support 99.9% of the SLA

1. 4. Standard (Standard)

(1) customer's computing resources are exclusive

(2) You can create an unlimited number of types Standard of the Azure Web Apps

(3) The maximum storage size that can be used is 50GB

(4) Scale -out capability supported, with horizontal support up to Ten an exclusive example

(5) Support 99.9% of the SLA

based on the above What is the disadvantage of Azure Web App ?

1. 1. single Web Apps Instance Size

single Azure Web Apps The maximum instance is Large , configuration is 4CORE/7GB . If the reader develops a Web applicationthat requires a single instance to run with a minimum of compute cells greater than 4CORE/7GB, the web Application is not suitable for deployment on the Azure Web Appspaas platform.

1. 2. Horizontal expansion Capability

in the Standard mode, Azure Web Apps Scale -out capability supported, with horizontal support up to Ten an exclusive example

1. 3. installing software is not supported

because it can't be passed Windows Remote Desktop or Linux SSH Management Azure Web Apps 's operating system, so Azure Web Apps Custom installation software is not supported

1. 4. not supported Azure Virtual Network Virtual Network

in the country by the century connected operation and maintenanceAzure China,Azure Web Appscurrently does not support adding toVirtual Networkvirtual network, so access is added to theVirtual Networkof theAzure VMsvirtual machine, you must passAzure VMsthe public networkIPorDNSaccess. To ensure safety, it is also recommended to combineAccess controllist (ACL)settings to use together.
