Introducing PaaS - Azure Tutorial

- [Instructor] Okay, so let's look now at platform as a service. Platform as a service will be critical to any efforts you make to innovate in the cloud. And the reasons for that are quite simple. Platform as a service offers a complete development and deployment environment in the cloud. And it enables you to build everything, from the simplest cloud app to the most sophisticated enterprise application. With platform as a service, you purchase the resources you need on a pay-as-you-go basis, only paying for the resources you need when you use them. Just like infrastructure as a service, platform as a service includes all of the infrastructure that you need. That is the networking and storage that's provisioned in the data center. As well as this, it includes all the middleware such as development tools, databases, management systems, and much more. It's designed to support the complete application development lifecycle, supporting you with building testing, deploying, managing, and updating your applications. There are no software licenses to deal with. All you need to do is manage the applications and services that you develop. And Azure takes care of everything else. Platform as a service has many advantages over a traditional infrastructure as a service approach. Firstly, it can drastically reduce the development time for your project, enabling you to deliver that customer value faster. Things such as directory services, authentication, and search are built right in. Because platform as a service comes with so many features built right in, you can add new features and capabilities without having to hire specialized staff. It's also much easier to build applications that target multiple platforms, including web, mobile, and desktop, again, making it easier to engage with customers. Another great benefit of platform as a service is that it gives you access to advanced, sophisticated tools such as machine learning and business intelligence that could well be unaffordable if you were to try and purchase them or license them outright. It's also much easier to build highly scalable and resilient applications. You want the amount of resources available to grow in response to the demand of your users, who also want your services to be available across the globe even in the event of a network failure. Platform as a service makes all of this possible.
