Home' Technology Review : September October 2013 Contents Data and information security, a problem well known by
companies with internal data centers, is an even more important
issue for IT professionals facing the challenge to select an external
private Cloud solution.
Indeed, hosting information, sensitive or not, at a third-party provider can raise doubts over the
data actual confidentiality, security and integrity. To guarantee a maximum level of security to
its clients, OVH.com followed a set of best practices to build its own Dedicated Cloud solution.
Secured data centers keep data safe
All the data on Dedicated Cloud are hosted on OVH.com’s own data centers, and built to
meet the Tier IV requirements. They are also designed and maintained by OVH.com. These
buildings are real fortresses, with the highest levels of security and able to resist any physical
intrusions. They are highly protected, equipped with a video-surveillance system, movement
detectors and a next-generation fire suppression system. The OVH.com technical teams are on-
site 24/7 to monitor the availability of resources and can reach the server rooms in just a few
minutes: in case a server has any problem, it is quickly replaced.
A redundant infrastructure for a near-total availability
To guarantee an SLA (Service Level Agreement) of 99.99999%, OVH.com has set up
emergency procedures to respond to any hardware failures. Every hardware equipment (storage,
servers, hosts...) is fully redundant to reduce any risks of downtime. These equipments also
include two separate power supplies and are connected to their own Uninterruptible Power
Supply (UPS). Same thing for the network: each equipment is connected - using 2 separate
ports - to two different switches, itself connected to 2 routers. The full redundancy of the
infrastructure allows OVH.com to guarantee its Dedicated Cloud customers a near total
availability of their resources, such as servers, storage or network. Therefore, the failure of an
equipment has no impact on the infrastructure or the data availability.
A focus on data backup
Because backing up the data stored in the Cloud is critical, Dedicated Cloud backup
solutions are RAID-10, at the least, offering an excellent level of protection. The same file is
written simultaneously on at least two separate disks, protecting the user’s data in the rare case
of a disk failure. Dedicated Cloud also provides snapshot backups which captures all the users’
data to create an instant backup. The customer can then restore all the virtual machines to the
same state as they were at a particular moment in time.
Totally isolated resources
All the user resources are interconnected using a private VLAN, thus completely isolating
it from the outside and the other Dedicated Cloud customers. To connect to vCenter, the
operations management suite for all virtualized resources, a user goes through an SSL tunnel.
This protocol relies on encryption to guarantee the security of all the data transferred. The direct
access to the virtual machines uses a virtual private network (VPN). The combination of a VPN
and an authentication token ensures that all exchanges are totally secured between the user and
the virtual machines. To protect even further vCenter and the virtual machines, users can limit
accessing to it from specific IP addresses. Finally, Dedicated Cloud integrates vShield Zones, an
application firewall for each virtual data centers, which protects the entire infrastructure.
Cloud Security: 3 questions to ask
before selecting your service provider
by Alexandre Morel,
Product Manager Cloud Computing at OVH.com
According to analyst firm Markess Inter-
national, the Cloud will grow more than 20%
until 2014. Indeed, from emerging startups
to large corporations, across all industries,
IT professionals are choosing to move to the
Cloud. But when faced with data migration
and the variety of offers from Cloud Com-
puting service providers, organizations have a
hard time choosing, especially when security
is a main concern. Here are a few questions
that IT professionals must ask themselves
before moving to the Cloud to ensure that
their data are kept in a safe place.
1. Does the service provider own its data
centers and network? Is it managing
and maintaining them itself?
2. What are the best practices the service
provider has put in place to guarantee
the maximum security of your data?
3. Are you able to retrieve all of your
data, at anytime and using a format
compatible with your own tools?
