The stratospheric rise of the cloud
Trust in the cloud is growing. While there is notable continued growth in use of the private cloud, some companies are beginning to migrate towards using public cloud infrastructure. However, such a migration requires several key prerequisites to be in place.
To what extent have companies developed their cloud-related activities?
the French market, adoption of the cloud is steadily progressing.
During Syntec Numérique's most recent bi-annual study that was
carried out by IDC, IT decision-makers were surveyed about the trends
they expected to see regarding the evolution of their infrastructure.
After cost reduction, the priorities they stated were the deployment
of a private cloud (for 58% of those surveyed, representing a 12
point increase on last year) and the launching of new services in the
public cloud (for 52% of those surveyed, representing a 6 point
increase on last year).
is not a single project that I work on which is not "cloud first"
oriented or at least cloud compatible. The cloud is seen as an
indispensable tool as part of a successful digital transformation
strategy. Big data notably requires more flexible and scalable
infrastructures, in order to deal with large volumes of data. By
reducing costs, the cloud enables companies to direct their budgets
towards financing innovative projects.
movement began two or three years ago with the creation of the first
private clouds. The latter were all about generating environments in
which production or testing could take place swiftly. Projects
focusing on purely public clouds are rarer in France than in the UK
or in Northern Europe. PostNL, the Dutch post office service has
placed its entire application portfolio on the cloud, for example.
The most popular trend remains the use of a hybrid public-private
cloud, which allows users to have the best of both worlds.
How can companies decide between the private cloud and the public cloud?First
of all it's all about defining the cloud strategy. Entering the
cloud is not just a question of technology: cloud migration will have
an impact on internal processes, but also on the range of skills
required within the company's IT department.
following step includes reviewing your applications portfolio. Based
on their stage of development and their profitability, some
applications will be either scrapped, rewritten or translated, in
order to make them cloud compatible, or indeed they may be replaced
by native solutions in a SaaS (Software as a Service) form.
comes the question of sharing the workload out between the public and
private cloud, and that choice depends on the material available. For
example, a company with a large volume of virtual servers that have
not yet been amortised will be more inclined to opt for the private
studying the volume, variability and, above all, the criticality of
data will narrow the choice down even further. Banks or "Vitally
Important Operators" (OIV in French) as defined by the French law
on military programming (LPM), are subject to regulatory conditions
that limit them in terms of where they can store their data. A
detailed analysis allows companies to divide information into
sensitive data that must be stored in France from what could be stored
opening of datacentres in France in 2017 by Amazon Web Services and
Microsoft Azure could remove the final hurdle, as the security hurdle
has already been removed. The level of security of Amazon, Microsoft
or other large cloud providers is no lower than that of private
infrastructures - on the contrary, in fact.
is a partner of all of these cloud providers, thus rendering our
advice impartial. We are also taking things forward to the next step,
which is IT containerisation. Being freed from the applications
environment, the concept of a virtual container allows companies to
utilise cloud services offered by any provider, rather than depending
on one in particular.
What is the role of the IT department in this cloud strategy?Despite
the appointment of a chief digital officer or the fact that an
ever-increasing share of the digital technology budget is no longer
under its control - 30 to 40% according to studies - the role of
the IT department remains a key one. Indeed, IT departments ensures
that businesses can benefit from IT production.
having overseen the conversion of servers into virtual form, the IT
unit can suggest a host of cloud services. The IT department becomes
almost a sales service, targeting specific domains. For example, it
can set up a digital factory dedicated to marketing analysis.
the IT department must continue to ensure that the existing IT
services keep on functioning. This means maintaining and updating the
current infrastructure, but carefully with regard to these legacy
systems. All new developments and recent applications will be
migrated to an infrastructure that allies both the public and private
clouds, for clients who subscribe to this bimodal IT system for their
