The cloud computing platform plays a "dream lover" role in the process of serving developers, PAAs also provides the services of cloud computing services and platforms for ordinary developers, while introducing open source technology in PAAs provides a fairly open and advanced technical support for this service platform, including Red Hat, VMware and others play an important role in this field.
PAAs and developers who play who
For developers and PAAs service platforms, there is no such thing as who is completely dependent, and it is generally understood that the user has a certain power over the tool platform, but does not fully apply to both the developer and the PAAs.
Three business models of cloud computing
For PAAs, as a can provide customers with relatively perfect software development and deployment of environmental services platform, although technically fully in line with the current technology development trend: Low energy consumption, easy deployment, quick to start, easy maintenance and low cost and so on, but still in the initial stage of development, including technology, Platform deployment development and service market improvement are still a long way to go, need more development, on this platform developers are also the most active drivers and promotion factors. The development of PAAs will benefit from applications developers who are unwilling to synthesize middleware components. The cloud platform is exciting because it provides users with the resources they need to develop, test, and deploy quickly, and at a low cost. The vast majority of PAAs users are still personal developers, primarily on the PAAs platform to build related simple applications. Although enterprise users are increasing, they are mainly for development and testing purposes. The main reason to hinder the use of PAAs by enterprise users is that today's PAAs products also have many flaws, such as security issues, information confidentiality issues, quality of service issues, and even app engine cannot guarantee the quality of its services.
PAAs settings
For developers, because the cloud infrastructure is rapidly evolving by providing an efficient working environment for rapid development and deployment of applications, PAAs further simplifies the application development process by filtering out virtual machines, operating systems, and other extraneous details that are not relevant to application development. So that the developer's efficiency and flexibility have been greatly improved. PAAs is a more efficient working environment for developers to modify existing applications or develop new ones.
When open source encounters PAAs
There are some problems with PAAs development, the first is that the programming languages that dominate the PAAs market have not yet led to the complexity of the PAAs-based development language, and the second is that the current PAAs platform is constrained by the non-standard framework, coupled with a lack of support for a variety of application services, caused many deployment problems, most notably the inability to deploy applications across private and public clouds. And a series of vendors such as Red Hat, VMware and so on, through open source PAAs to achieve better deployment results, but also for the cloud computing environment to design open source architecture.
Red Hat OpenShift
The open source PAAs platform gives developers a much better ability to deploy, run, and extend applications in a cloud environment, and supports the broadest range of public cloud and private cloud, an industry-standard, efficient development framework, and application infrastructure services.
Open source PAAs to help developers
Developers will like to develop applications at the open source PAAs level in the future because it provides a relatively high-end operating environment. At the same time, open source PAAs will provide developers with a complete set of development and testing environments, with a PAAs-provided tool to deploy an application to the cloud, possibly with just a few mouse clicks and more than 10 seconds to complete.
At the PAAs level, the service platform provides a relatively high-end execution environment, and the open source PAAs platform encapsulates the infrastructure-related details so that developers do not have to deal with how the server should be scaled to meet the required scale of service. Of course, there is no need to think about how to handle load balancing and fault tolerance between servers. Open source PAAs enables developers to face a highly abstract execution environment and provides developers with the necessary environment and tools, which allows developers to work on programs without carefully figuring out the details of the various system operations. Mature Open Source PAAs platform service providers generally have extensive experience in building large system architectures, such as Red Hat, VMware, and so on. With its already mature platform and technology, it can be combined with open source PAAs platform to provide a unique application experience.
See open source PAAs through Red Hat OpenShift
Taking Red Hat OpenShift as an example, it enables developers to better utilize the industry's broadest range of middleware services through the ecological environment of JBoss. And because OpenShift supports a large number of frameworks and languages, Java, PHP, Python, and Ruby, it can provide a more comprehensive set of features for developers of cloud computing.
The way developers write programs and submit applications is being transformed and reformed by Open source PAAs, and development platforms and service applications are becoming increasingly active in the industry. Red Hat OpenShift can provide developers with more flexibility, while supporting more development frameworks for Java, Python, PHP, and Ruby, including Spring, Seam, Weld, CDI, Rails, Rack, Symfony, Zend Framework, Twisted, Django, and Java E. It contains SQL and NoSQL data storage and a distributed file system. Red Hat OpenShift enables developers to build, test, run, and manage related applications through support in the cloud architecture, development language, and cloud framework. OpenShift is based on Red Hat JBoss expertise while owning innovative features and extends PAAs capabilities to richer and more demanding applications. As one of the leading sources of open source technology, Red Hat OpenShift helps developers free from the lock on the PAAs platform, allowing developers to choose cloud providers freely.
In enterprise-level development and cloud applications, open source PAAs also has a major impact. OpenShift is also the first public PaaS to provide Red Hat enterprise-class JBoss services, and can provide enterprise-level developers with a faster way to deploy cloud environments and technologies. Based on the experience and ecological environment of Red Hat in operating system, virtualization and JBoss Enterprise Middleware, OpenShift can greatly meet the needs of new cloud developers and enterprises.
In the increasingly open source era of cloud computing, open source PAAs will become the future "Top Dream Lover" of developers, while the development of open source technology in conjunction with the PAAs platform will also provide developers with a rapid development and deployment of cloud environment a sharp weapon.
