With the evolution of cloud computing era, there is rapid change in the deployment process of a web-application. This brings out various concerns like server crashing, server maintenance and the fact that patching still must be managed when using IaaS (Infrastructure as a service) model. A cloud vendor only takes care of the underlying environment on which the service has been created or deployed.
In PaaS service, Azure has come up with a dedicated service which makes our life simpler.
Using Azure WebApp, the user can leverage various facilities such as:
- Multiple language and Framework support: · The WebApp support ability with ASP.Net, Python, Java etc.
- DevOps optimization: It will help to organize continuous integration and deployment with help from Visual Studio Team services, Git Hub etc.
- Security: Azure WebApp is ISO, SOC and PCI compliant.
- Backup Configuration: Azure WebApp provides flexibility to configure the backup policy as per the desired requirement.
It helps us to scale up and scale down the number of instances depending on the number of user workloads as well as high demand of the application. Scaling depends on the threshold value which gets configured during the creation of the WebApp.
Apart from the above-mentioned features, WebApp also provides basic Monitoring alerts to the user like HttpRequest, Average Request Time, CPU utilization etc. Along with the mentioned feature, we can choose the application environment based on the framework provided like .Net framework version, java version, Platform architecture version like 32bits or 64bits.
Generally, WebApp makes use of two environments for its deployment which are App service plan and App Service Environment. An App service plan makes use of multi-tenant environment for the resource deployment whereas an App service environment makes use of isolated, separated and dedicated environment for the resource deployment.
It comes with a default wild card SSL certificate which enhances the security of the WebApp, allowing us to configure our own SSL certificate to minimize the attacks on the web-application. WebApp also supports the configuration of Application insights which is a monitoring tool that helps to provide telemetry about the performance of application deployed in it on multiple Metrix selection.
The WebApp can become more powerful when the user has more access to install desired application on it apart from Azure preconfigured installation.
At the end, it totally depends on the requirement for which the platform is chosen. If PaaS (Platform as a Service) is chosen, then Azure WebApp would be the game changer in the hosting environment.
