Sometimes, synchronizing development teams’ efforts may be difficult. The contributing factors include ✓ Teams that are distributed across business units or different geographic regions of a company ✓ Software code that needs to work across multiple platforms and devices ✓ Software development process that requires individual components that all need to work together in a service oriented way ✓ Market dynamics that lead to faster software development lifecycle The software quality and time to develop may suffer unless the team has a way to test for, locate, and fix errors early in the software development process. While it can be hard for development teams to keep in synch in traditional software environments, these challenges can be magnified in PaaS because of the increased speed of development. In PaaS, continuous integration is easier because the IT staff doesn’t need to install and manage new hardware and software or manage many other aspects of overall platform infrastructure. In fact, PaaS helps to make possible a very aggressive form of continuous integration that’s required to support the fast-paced and highly-iterative development process needed to develop Software as a Service (SaaS) solutions. The Role of Application Development Services Application development services are the core of PaaS support for the development process. They’re the anchor services that streamline the process of developing applications in the cloud. A PaaS platform

Chapter 3: Looking at PaaS as a Development Platform 27 ✓ Provides the developer with a complete environment to provision, develop, build, test, and stage applications ✓ Abstracts the details from the developer so developers can focus on the task of coding and not on supporting the systems needed for development and testing An integrated development environment (IDE) is a software application that includes all the tools that a software developer needs to develop software. Typically, the programs included in an IDE can be used to write, change, compile, deploy, and debug software. IDEs are commonly used by developers on their desktops in traditional environments and can also be used with shared cloud services when using PaaS. When the IDE is used with the cloud, you, as the developer, have some key advantages: ✓ You can still use your existing IDE on your desktop, but it becomes much easier and faster to share your code with other members of your team. ✓ You can push your code into a shared repository in the cloud so everyone has immediate access to the same code and tools. ✓ You can test your code during development against the same systems your end-users will access, using services provided by the PaaS. As a result, errors in the code are found earlier, and the resulting applications are delivered faster. A well-designed PaaS environment has enough flexibility and modularity that it can be useful in many different scenarios and handle a wide range of development objectives. In addition, the PaaS environment must be able to support the developer with a wide range of services that encompasses the entire software development lifecycle. To ensure that your PaaS provider offers the right set of flexible services so you can make the most of your PaaS development environment, use the following checklist:
