About Customer
Sovos Turkey, part of the global tax compliance leader Sovos, entered the Turkish market in 2019 by acquiring Foriba, a pioneer in e-invoicing and e-transformation solutions. In 2022, it expanded further by acquiring Digital Planet, enhancing its Istanbul-based development center. Sovos Turkey specializes in e-invoicing, e-ledger, and VAT compliance, serving enterprises and SMBs across Europe, the Middle East, and Asia with scalable cloud solutions for digital tax mandates.
Project Requirements
Sovos is having Public and Private Cloud services distributed over 8 different Cloud Service Providers (CSP). This is having the following challenges:
- Different DC & service providers contracting for new customers causes a longer sales cycle.
- Not all data centers can provide expected SLA’s.
- Current RPO is 24 hours.
- Current infrastructure does not allow for application consistent continous replication to a DR site.
- Some of the existing DCs are having storage capacity issues.
- Currently 50% of HSM infrastructure is in end-of-support status.
- TRA Audit requirements cannot be met with existing infra and services causing a TRA Rating 70%.
- Systems are vulnerable to all security threats
Project Details
Existing DC’s: 8 DCs (6 Local, 2 Public Cloud)
Private Cloud Capacity: ~110 VMs (500 vCPU, 2,7 TB vRAM, 70 TB vDisk)
Public Cloud Capacity: ~60 VMs (290 vCPU, 1,5 TB vRAM, 310 TB vDisk)
Total Downtime: 3,5 hours
Project Duration: 2 years
Strategy & approach
Tools & methods used
Partner Migration Tools
Azure Native Tools
AWS Native Tools
SAP System Installation Tools
There are 2 types of customers for Sovos. Private Cloud and Public Cloud customers.
In the first phase, Private Cloud Customers (30+) migrated from 4 different Data Centers.
In the second phase, 20K+ Public Cloud Customer systems (100+TB Oracle DB) migrated from another Data Center with a 3,5 hours downtime.
Following phases consolidated the remaining workloads on other data centers.
Achieved results

Public Cloud system deployed on an Oracle RAC cluster to increase availabiliry.
TRA Audit
TRA Rating increased by 29%. 5651-Legal Logging with 2 years retention. High Availability for Layers of Production Site.
Improved HSM Availability
Outdated/mulfunctioning and partially Sovos owned HSMs replaced with brand-new redundant HSMaaS on both Production & DR sites.
Business Continuity
Tier-4 DC (KKB) for Production Site. High Available HSM infra for Prod & DR. 5 min RPO and 30 min RTO to met Enterprise Customers and TRA requirements.
Improved Security Posture
Dedicated HSM’s for Sovos. OS VuM for Public and Private Cloud Systems. Separate VLAN for UAT and PRD. PAM for Server Access. Dedicated VDOMs. IPS/IDS, DDoS, WAF, Load Balancer
