Several of the industry’s top experts have debated, at a roundtable organized by ComputerWorld, the challenges and benefits of migrating to the public cloud.

The coexistence of three models of cloud: private, hybrid and public are necessary or the first two are two mere tributaries that will ultimately lead to public cloud as a single solution? Trends indicate this. In fact, only in the last two years have companies begun to value the option of migrating applications called coreto this support. In addition, according to a recent JP Morgan report of 2016, 16.2% of its applications ‘run’ in public cloud, a percentage that is expected to grow to 41.3% by 2020. We are facing a change of scenery towards a digital model that raises many questions: What are the challenges ?, and, the advantages? Is security a sometimes insurmountable barrier to deploying cloud applications for critical business services?

“Last year we implemented a private cloud, but we were a bit disappointed. It has not really brought us competitive advantages . However, we have been able to redirect the shots to the public cloud, “Javier García, Repsol’s IT services and operations manager, said during a round table organized by ComputerWorld and has brought together several of the industry’s most important voices when it comes to addressing public cloud issues.

As for concerns, security is a more than obvious concern , “but once you get past that barrier you realize that you’re safer than on-premise models ,” Garcia himself said. Jose Bonnin, director of the business unit of cloud and enterprise of Microsoft, that endorsed the affirmation providing the data that once given the passage to the cloud world the security low of the first to the fifth position of the ranking of the preoccupations of the CIO.

Most of the participants claimed that, little by little, they were taking their applications to the public cloud , although they were still skeptical about their core . The starting point, they said, is for a ‘Cloud First’ strategy that is based on the approach as a basis for bringing workloads to the cloud before raising any other model. “Then, depending on the analysis, we will study what can be carried, what needs to be changed and what should be left as it is,” said José Luis Angoso, Acciona’s director of applications. “And, in addition, we still have to solve elements that scare top management.” In this sense, the recipe of Teresa Oliva, director of the IT and cloud modernization business area, is clear: “It is important that companies that go up to the public cloud are not afraid, trust is key.”

On the other hand, the debate focused on the SAP challenge in the public cloud. José Ramón Lucas, managing director of Accenture believes that “just thinking about SAP in the cloud already breaks many barriers. Between two to five years is going to end up bringing the whole core of SAP to the cloud. “
