Interop: Infrastructure Cloud Services (IaaS) have shifted to PAAs

Cloud service providers, which originally provided infrastructure as services (IaaS), began moving the stack to the platform, the Services (PaaS) market, to diversify their portfolio to meet the growing demand for cloud-based development services from customers.

The latest example of IaaS transfer to PAAs is Tier 3, where Tier 3 introduced PAAs and database-as-service (DbaaS) products at this interop conference.

Philbert Shih, analyst at the Businessesflat-out Institute, said the service provider's actions were slow and steady, and there would be no significant changes from IaaS to PAAs, but only some progress. "All major suppliers will end up on this path," he says. "The technology is ripe, it's just a matter of time, and development work and platform improvements will be provided by suppliers." ”

The biggest driver of PAAs products is customer demand, he says, and he has not yet seen a huge demand for PAAs services from customers. Companies first have to adapt to cloud computing before they are likely to consider moving the stack up to the PAAs environment. This allows customers to design, develop, and deploy applications entirely in the cloud environment, reducing the need for IT resources within the enterprise.

Different IaaS vendors are taking different approaches to accessing the PAAs market. , some vendors use mergers, acquisitions and partnerships to build PAAs products. At&t, for example, announced last November the launch of a product that integrates Longjump platform services. VMware's Cloudfoundry is an open source PAAs module that has started to be supported by other Open-source cloud vendors. Piston Cloud Computing recently announced that it will build a partnership with VMware and use Cloudfoundry to eventually support this VMware-supported project in OpenStack. Some traditional software, such as Salesforce.com, has also begun to consider moving to the PAAs market, while Windows Azure is a purely PAAs product.

"This is an irresistible trend," says Rich Wolski, founder and chief technology officer of Eucalyptus, the Open-source IaaS provider and cloud industry observer. "In terms of technological innovation, natural progress starts at the bottom of the stack and then goes up, just like the development of cloud computing." "The first is infrastructure, then PAAs," he says. "Eucalyptus is evaluating how to penetrate the PAAs market.

For Tier 3, moving to the PAAs market is "very meaningful", said Agatha Poon, a 451 research group Cloud analyst, as a pure cloud supplier with technical expertise and infrastructure to support PAAs products. Most of the infrastructure of Tier 3 is run in VMware environments, and they use Iron foundry as the basis for PAAs products, Iron Foundry is an open source project that enables. NET programming languages to be used in cloud foundry platforms. The company says Iron Foundry has more than 400 active users and more than 500 applications. The Tier 3 Web Fabric PAAs product will support application development and development across multiple languages, including. NET, Java, Ruby, PHP, and Python.

One of the distinctive features of the Tier 3 Web Fabric PAAs product is the integration with the underlying IAAS, Tier 3, founder and chief technology officer Jared Wray said, "Essentially, we can create value when you can combine infrastructure and platform providers." We know how to integrate them to improve performance and automation. ”

Tier 3 's web fabric and data fabric (the newest Dbaas product) allows for the migration of workloads between PAAs, IaaS, and Dbaas. "From the end-user's point of view, if you can provide them with the products they want, that's enough to attract customers," she says. "Customers like to choose very experienced suppliers." ”

Overall, Poon says, she wants to see more cloud vendors expand to other products, not just as IaaS suppliers. (
