PAAs promises to develop in the cloud

Well-known it media infoworld that in the cloud computing trend, the platform is the fastest growing area of service. Gartner predicts that the global corporate market for PAAs platforms will increase from $900 million trillion in 2011 to $2.9 billion in 2016, with a compound growth rate of 26.6% per annum.

The problem is that no two PAAs platforms are the same. Moreover, as the market expands, it is even more puzzling that all things that look like development have been PAAs marked. As a result, vendors are promoting PAAs clouds, and in fact only a handful of big vendors are developing PAAs rules.

The main PAAs suppliers are Amazon, Red Hat, Google, Microsoft and so on. Other vendors are in the fight, and the sector is moving toward large architectures and development, both of which are covered by core vendors. The reality is that small suppliers don't have the money to invest, so big suppliers aren't worried. As a result, small suppliers will soon develop.

The scale of this architecture is more influential than the choice of vendors. The major PAAs providers (Google and Microsoft) build greater and better storage, database, and computing services for application operations. In other words, they move the stack from the PAAs to the IaaS. Others, such as Amazon, move from IaaS to PAAs or higher stacks.

The obvious trend for manufacturers is that they need IaaS in the PAAs, otherwise Sol will be used. For it and developers, this means that application development and raw cloud capacity become part of a large cloud environment, which is developed in the cloud.

This is the industry direction, and the best way is to use PAAs as a way to extend the core cloud services to solve business problems. IaaS is an architectural resource pool, such as the storage, data, and computing resources you need to perform these services. PAAs is how you convert these services into applications and business processes. Because applications and their schemas are in the cloud, you can use the ever-increasing set of services and feature sets to manipulate these applications.
