Hybrid & Private Cloud
Not every workload belongs in the public cloud. We design hybrid and private cloud architectures on AWS that secure your data sovereignty and meet regulatory requirements.

Hybrid & Private Cloud
Not every workload belongs in the public cloud. We design hybrid and private cloud architectures on AWS that secure your data sovereignty and meet regulatory requirements.
Hybrid & Private Cloud
Your data stays where you decide.
Regulatory requirements like GDPR, BSI C5, or industry-specific mandates restrict what can go into the public cloud. Tallence resolves this tension with hybrid and private cloud architectures that connect both worlds.
We design, implement, and operate hybrid cloud environments where private cloud, on-premises infrastructure, and AWS work together as connected, independent entities. Workloads are placed deliberately based on data sovereignty, latency, and cost requirements.
What is hybrid and private cloud?
Definition
A hybrid cloud lets your organisation run workloads across public and private environments while keeping them connected through a shared management layer. You decide where each workload runs based on regulatory requirements, latency needs, or cost constraints.
A private cloud gives you a dedicated environment with full control over data, network, and configuration. No shared tenancy. For organisations subject to GDPR, BSI C5, or sector-specific regulations, this isolation is a compliance requirement, not a preference.
A sovereign cloud adds jurisdictional guarantees: data processing and storage happen exclusively within the EU, with full auditability and compliance controls built into the platform layer.

Model comparison
Private, hybrid, sovereign, or public?
Eight criteria, four models. Find the model that fits your requirements.
Digital sovereignty
What sovereign cloud actually means.
Digital sovereignty is not a marketing term. The EU Cloud Sovereignty Framework (CSF v1.2.1) defines eight measurable dimensions for evaluating cloud providers. Tallence prepares your environment for these requirements.
Strategic sovereignty (SOV-1)
EU ownership and independent governance. The ownership structure of the cloud provider determines which legal systems it is subject to, regardless of where data physically resides.
Legal and jurisdictional sovereignty (SOV-2)
Local contracting entity in the EU. Data residency and jurisdiction are two different things. Tallence advises you on the legal implications of your architecture decision.
Data and AI sovereignty (SOV-3)
Customer content and metadata remain in the EU. Physical and logical separation prevents access by operators or third parties.
Operational sovereignty (SOV-4)
EU-based operations and support, full observability (logs, metrics, traces). No black-box operations that restrict auditability.
Supply chain sovereignty (SOV-5)
No critical dependencies on non-EU components. Essential for geopolitical crisis scenarios and critical infrastructure requirements.
Technology sovereignty (SOV-6)
Open standards, IaC with Terraform/OpenTofu, API portability. Prevents vendor lock-in and enables multi-provider strategies.
Security and compliance sovereignty (SOV-7)
BSI C5, ISO 27001, IT-Grundschutz, policy enforcement. Technical guardrails enforce compliance ex ante, not just at audit time.
Environmental sustainability (SOV-8)
Transparent CO2 and water reporting, renewable energy sourcing, measurable PUE. Long-term resilience includes energy dependencies.

AWS technologies
The AWS building blocks for your hybrid architecture.
Tallence uses proven AWS services to establish secure and performant connections between your on-premises environment and the AWS cloud.
AWS Direct Connect
Dedicated network connection between your data centre and AWS. Low latency, consistent bandwidth, no public internet.
AWS Outposts
AWS infrastructure in your data centre. Same APIs, same tools, same hardware as in the AWS cloud.
AWS VPN
Encrypted site-to-site connection between your on-premises environment and AWS VPC. Quick to set up, cost-efficient.
Amazon EKS Anywhere
Kubernetes clusters on your own infrastructure, managed with the same tools as AWS EKS.
AWS Transit Gateway
Central hub for connecting VPCs, on-premises networks, and remote locations.
AWS IAM Identity Center
Centralised identity and access management across all environments.
Use cases
When hybrid and private cloud is the right choice
Regulated industries
Financial services, healthcare, and public sector with strict data localisation requirements. Contact us if you are unsure which model fits your requirements.
Learn more →Intellectual property protection
Research data and proprietary algorithms that cannot run in shared infrastructure.
Learn more →Data sovereignty
Companies that must ensure data does not leave EU jurisdiction.
Latency requirements
Workloads with hard latency requirements that need proximity to the data source.
Learn more →Legacy integration
Existing on-premises systems that cannot be migrated but need to consume cloud services.
Disaster recovery
Geo-redundant protection of critical systems with defined RTO and RPO targets.
Why Tallence
Hybrid cloud needs more than architecture slides.
AWS expertise meets on-premises experience
We know both sides: AWS-native services and operating infrastructure outside the public cloud.
Compliance built in
GDPR, BSI C5, and ISO 27001 are not afterthoughts. We embed compliance from day one.
No vendor lock-in
We are vendor-independent. Our recommendations are based on your requirements.
Operations included
Tallence Cloud Foundation operates your hybrid environment as a managed service.
