Shulou(Shulou.com)06/02 Report--

This year is also a very busy year, until the end of the year began to have a little time to post some of this year's blog.

This year, the main effort is in Azure. Azure, as one of the best public cloud services in the world, is still worth learning. Whether in China or Global, Microsoft provides a lot of services to customers. At the same time, Microsoft is also one of the few public cloud providers in the world that can provide services to customers from SaaS to IaaS. It is expected that more blog about Azure will be shared in the future.

Today, let's share a little bit about the migration of Azure web app. Let's first introduce some content about Azure web app.

First of all, Azure web app is different from the traditional IaaS VM, but a PaaS platform hosted by Microsoft. In the past, if we wanted to publish a website on internet, we needed to first have a VM or physical machine, then install the operating system, then deploy our code to this server, debug our IIS or tomcat, and then let the person in charge of the network make the server accessible to external users through reverse proxy or other means. The follow-up operation and maintenance of this server will be handed over to colleagues in charge of operation and maintenance to carry out some regular patch maintenance and inspection.

With Azure web app, users only need to care about the content in the code. As a PaaS platform, the operation and maintenance of the underlying OS and the maintenance of the physical server will be done by Microsoft, so there is no need to worry about it.

In addition, Azure web app can also be devops-style, with continuous deployment from VSTS, GitHub, Docker hubs, and other sources, as well as package management, transition environments, custom domains, and SSL certificates. Azure web app itself mainly supports the following languages, including ASP.NET, ASP.NET Core, Java, Ruby, Node.js, PHP or Python. Basically, mainstream programming languages can support it.

In addition, Azure web app can also achieve the auto scaling mode. The backend enables multiple azure web site instances to carry traffic together and dynamically expand according to CPU and other performance data, so as to respond quickly to the website performance problems caused by heavy traffic and ensure the usability of the website.

To sum up, Azure web app has the following major advantages:

1. Managed services, no need to care about the maintenance of the underlying hardware and OS

two。 There are many languages supported, and the mainstream languages basically support it.

3. Can be combined with platforms such as Git,Github,VSTS for continuity and deployment

4. Can be scaled automatically according to the load

5. You can use different slot to switch between Prod and test environment

Having said that, let's take a look at how to create Azure web app.
