Consolidate, extend, transform … so much action is needed to create a hybrid cloud environment. This is also where increasing complexity and increasing costs come into play. These are the conclusions we can make at the end of Matinale IT For Business “Ensuring control over your hybrid cloud.”
If the hybrid cloud is still the cloud vision for many companies in France, its long -term management is painless, an IT For Business Morning revealed, which took place on 16 September.
If there is a hybrid cloud, it is because companies consider the private cloud to be more secure and more sovereign than the public cloud. However, as pointed out by Eric Beaudet, senior analyst at Teknowlogy / PAC, the public cloud, which is experiencing stronger growth in France (+25% per year, versus 5-10% per year for the private cloud) is remains targets of choice, including the historical sectors considered most critical. “Some banks are now ready to move their ‘core banking’; that’s a big change.” And some small banks even see the public cloud as an accelerator and are betting on the public IaaS strategy to an extent that they will be “full cloud in 8 years”.
It’s true that “hybrid cloud is still complex, recalls Eric Beaudet. French companies combine a public cloud with a private cloud in the case of a Cloud explosion – to manage seasonal traffic peaks, for example.Some are gradually shifting their workloads, finding themselves struggling “in a bimodal environment, which is very difficult to maintain,” he explains. “The hybrid cloud adds complexity to the orchestration and thus causing an increase in costs. These costs are particularly difficult to assess for hyperscalers and the bill can explode quickly, ”the analyst said.
The complexity of the hybrid cloud comes mainly from the diversity of technologies to be supported. We use different technologies [d’un cloud à l’autre] and the hybrid cloud creates change ”, testimony Simon Decarpentries, Enterprise Solutions Sales, at NetApp, specifically pointed to containers.
Managing data in a hybrid cloud environment is also an obstacle course, he noted in essence, citing data transfer and security issues. “How exactly do you manage a database in the public cloud with on-premise data”, also wonders Aurélien Kiener, Cloud Solution Specialist, in Digora. “Where to put data for optimal performance and how to manage security. Finally, many companies have rallied, according to him, in the cause of DbaaS (database as-a-service) and completely migrated their processing to the public cloud.
From this heterogeneous fleet also arose the need to unify the management and security of this distributed environment. Tracking the side of the hybrid, if there are tools, the task remains difficult. “We don’t manage, or small, to have an equivalent level of oversight”, testimony Fathi Bellahcene, Head of architecture, at Veepee, an ecommerce specialist. And it’s even harder in SaaS environments, like Office 365 or GDrive.
Because hybrid, naturally more open, increases attack potential, having a global view of security is, again, a necessity, agrees, Philippe Rondel, Senior Security and Evangelist at Checkpoint. It is important “to consolidate access controls. […] Identity management is key in the hybrid cloud. The cloud rhyme with openness. It is important to know who is connecting to the data. And too complicated to manage.
Finally, there is the question of costs. “There’s a real cost to entering the hybrid. It’s not neutral and very high,” said Fathi Bellahcene (Veepee), relying on her own experience.
If this can be interpreted by combining new management and security tools to manage the distribution of processing, applications and data, this increase in costs also comes from a human factor. With the proliferation of technologies, we are also proliferating in-house experts. This is one of the points raised by Olivier Gerling, Sales Specialist at Volterra. “The public, private or cloud edge creates loops and it is expensive. Having a unified infrastructure makes it possible to manage practice problems and avoid the proliferation of experts in certain fields and technologies”. Acquiring new skills remains long and costly for companies.
