YAS · SENEGAL
A geo-redundant cloud
for Senegalese businesses.
Two geo-redundant data centres, built and then operated by Synelia: the foundation on which YAS offers its B2B customers a cloud service hosted in Senegal — one that runs, for example, SEN’EAU’s infrastructure.
THE CONTEXT
An operator becoming a trusted hosting provider.
Senegalese businesses and institutions need to host their systems close to home, with high availability and data that stays in the country.
YAS entrusted Synelia with building a cloud infrastructure spread across two geographically separate data centres, then running it day to day: YAS sells the offering, Synelia runs the platform.
THE CHALLENGES
Three objectives
to deliver together.
Sovereignty
Data hosted in Senegal, under the operator’s control.
A commercial offering
Resources provided to B2B customers — isolated, metered and billed.
OUR RESPONSE
What we
built.
Two geo-redundant data centres
Two separate, replicated sites, built to withstand the loss of an entire site.
Data replication
Storage and databases replicated between the two sites.
Automatic failover
In the event of an incident, services fail over to the second site.
Per-customer environments
Each B2B customer has isolated, dedicated resources.
Operated by Synelia
Monitoring, maintenance, security and upgrades of both sites, handled by our teams.
Security
Network segmentation, access control and backups.

OPERATIONS
YAS sells the cloud.
Synelia runs it.
Once the platform is live, our teams operate it: both sites are managed as a single whole.
01
Monitoring
Availability, capacity and replication status monitored continuously across both sites.
02
Maintenance
Updates, patches and maintenance of the equipment and the virtualisation layer.
03
Continuity
Inter-site failover procedures, recovery tests and verified backups.
04
Security
Segmentation, privileged access control, vulnerability tracking.
05
Customer support
Provisioning of environments for YAS’s B2B customers and support for their migrations.
06
Upgrades
Additional capacity and new services as the offering grows.
