IT Architecture and Cloud Consulting

We help you decide, based on data, whether your applications should run in the public cloud, in your own data center or in a hybrid setup that combines the two. We prepare the target architecture and roadmap, migrate workloads to the cloud or to a hybrid setup in a planned way and make costs traceable.

When do architecture and cloud decisions come up?

Architecture decisions affect cost, security and flexibility for many years. That is why we compare the options against the same criteria before a decision is made.

  • Cloud costs need to be tracked more closely. Seeing which team and product each cost belongs to makes budget planning easier.
  • Workloads moved to the cloud have not delivered the expected efficiency. Servers moved as is may need to be revisited with managed services and right-sizing.
  • Data center hardware is approaching its refresh cycle. A comparative decision is needed between refreshing, moving to the cloud or building a hybrid setup.
  • Critical systems depend on a single location. There should be a plan for how services continue when a server, region or connection goes down.
  • Data residency and regulatory requirements need to be clarified. Determining which data can be stored where is a prerequisite for projects to move forward.
  • Virtualization licensing terms have changed. The total cost and risk of staying on the current platform and of moving to alternatives should be compared.
Scope

What do we do in cloud and IT architecture?

Design, migration and operations planning for infrastructure and cloud architecture.

Target architecture and roadmap

A phased architecture plan that can be budgeted, starts from your business goals and documents the reasoning behind each option.

Cloud foundation (landing zone)

Account structure, identity and access, networking, security policies and cost tags; a foundation built as code before workloads arrive.

Migrating workloads to the cloud

Moving workloads from physical and virtual servers to the cloud, with an inventory, a migration strategy and a downtime plan.

Cloud repatriation

Planned migration of workloads to your own data center or to a local cloud provider, for cost, performance or regulatory reasons.

Hybrid, multi-cloud and multi-site

Designing networking, identity, backup and management as a single whole across data center, branch and cloud environments.

Cost management (FinOps)

Cost visibility by team and product, budget alerts, right-sizing of resources and regular cost reviews with your teams.

Virtualization and VMware alternatives

VMware, Hyper-V, Proxmox or OpenStack virtualization; planned migration from platforms whose licensing terms have changed.

Continuity and disaster recovery

High availability, backup strategy, downtime and data loss targets (RTO/RPO), and regular recovery drills.

Not every application needs to move.

In a cloud migration, the right strategy is chosen separately for each application. Sometimes the best decision is to leave an application where it is or to retire it.

rehost

Lift and shift

Moving the application as it is. It is fast but the gains are limited; it is often the first step.

replatform

Move with minor changes

Moving to managed services with small changes, for example moving the database to a managed service.

refactor

Re-architect

Turning the application into a cloud-native architecture. It takes the most effort and gives the most flexibility.

repurchase

Replace with SaaS

Replacing an application you built in-house with an off-the-shelf SaaS product that meets the need.

relocate

Move the platform

Moving the virtualization layer as a whole to another infrastructure, without touching the applications.

retain

Keep in place

If there is no reason to move it today, leaving the application where it is and revisiting it later.

retire

Decommission

Shutting down applications that are no longer used; this directly reduces migration scope and cost.

Decided per application

The strategy for each application is set individually, together with its cost, risk and business value.

Process

We measure before we decide.

Every architecture recommendation is based on data about your current state and on your business goals. We present what we recommend and why, with written reasoning.

What we weigh in architecture decisions

We compare every option against the same criteria:

  • Total cost of ownership
  • Security and regulatory compliance
  • Scalability and performance
  • Your team's ability to operate it
1

Inventory and analysis

We map out applications, dependencies, data flows and current costs.

Output: Inventory and dependency map
2

Options and target architecture

We compare the alternatives in terms of cost, risk and time, and decide together.

Output: Target architecture document
3

Migration plan

We set the migration order in waves, the rollback plan and the downtime windows.

Output: Phased migration plan
4

Implementation

We build the infrastructure as code, then migrate and validate workloads in waves.

Output: Migrated and validated workloads
5

Optimization and handover

We tune cost and performance, embed cost tracking in your teams and hand over with documentation and training. If you wish, we continue with periodic cost reviews.

Output: Optimization report, documentation
Deliverables

Outputs of the architecture and migration work.

Deliverables depend on the scope of work; the reasoning behind decisions and the definitions of what was built are documented and in your hands.

Architecture documentation

Target architecture, network and security design, decision records.

Cost analysis

Comparison of current and target costs, savings recommendations.

Infrastructure code

In implementation projects, versioned definitions of the new environment written in Terraform and Ansible.

Migration, rollback and exit plans

Steps, checks and a rollback path for each wave; a way to switch providers when needed.

Disaster recovery plan

Backup, recovery procedures and drill results.

Knowledge transfer

Hands-on training for your team on operating the new setup.

Technologies

Technologies chosen to fit the need.

We evaluate the options against your requirements, your existing investments and your team's capacity to operate them. Where possible, we prefer open standards and portable tools.

Who it is for

Cloud and architecture work at your scale.

SMEs

Work usually starts with a hardware refresh or a first cloud decision; the aim is a simple setup with predictable costs.

Growing companies

Making cloud spending visible, organizing the account structure and connecting new locations to a common architecture.

Regulated and enterprise organizations

Building data residency, continuity and audit requirements into the architecture from the start.

Before we start

Making the first meeting productive.

None of these is a prerequisite; whatever you have makes the first conversation more concrete.

What you can prepare, if available

  • A breakdown of your cloud bills for the last few months, or your hardware and license costs
  • An application and server inventory, and architecture diagrams if available
  • Hardware and license renewal dates
  • Data residency, continuity and regulatory requirements
Frequently asked questions

About IT architecture and cloud

References and standards

No. The cloud has the advantage for variable workloads and rapid growth; for steady, high-volume workloads, your own infrastructure can be more economical. That is why we make the decision together, based on your current data.

The same criteria for each: workload variability and expected growth, total cost of ownership over several years, data residency and regulatory requirements, continuity targets and your team's ability to operate the setup. Variable, fast-growing workloads are often more economical in the cloud, and steady, high-volume workloads on your own infrastructure; the result is frequently a hybrid setup that combines the two.

We plan to keep downtime to a minimum. Workloads are moved in waves with a rollback path ready; downtime windows for critical systems are agreed with you.

A landing zone is the cloud foundation made up of account structure, identity and access, networking, security policies, logging and cost tags. It is built as code before workloads are migrated; fixing it later means changing the foundation underneath applications that have already been moved.

It depends on your workloads, your current license term and your team's skills. We put options such as Proxmox, Hyper-V, OpenStack or virtual machines on Kubernetes side by side with staying on the current platform, compare their total costs, and plan a phased migration if one is needed. We handle server and storage sizing together with our enterprise hardware service.

Which data can be stored where is one of the first architecture questions. We classify the data and design options that keep what is required with providers or in regions within Türkiye and leave the encryption keys under your control. Technical and administrative security measures are covered by information security consulting.

RTO (recovery time objective) is the maximum time within which a system must be running again after an outage. RPO (recovery point objective) expresses the maximum acceptable data loss as a period of time, for example the last hour of data. We set these targets together for each system based on business impact and design the backup and recovery setup accordingly.

We address this risk from the start. We prefer portable tools such as Kubernetes, Terraform and open data formats, and use provider-specific services deliberately and for stated reasons. We also write an exit plan alongside the target architecture.

Yes. For cost, performance or regulatory reasons, we move workloads back to your own servers, a rented rack in a colocation facility or a local cloud, in a planned way and in waves. In most cases, the result is a hybrid setup in which some workloads stay in the cloud.

Yes, if there is a reason for it: regulation, continuity, latency or a specific service. Because multi-cloud and multi-site setups increase the operational load, we design the networking, identity and monitoring layer as a single whole from the start.

Yes. If your own team will carry out the implementation, we work on the design and roadmap and, if needed, provide consulting support during implementation. The output is a target architecture document, decision records, a cost comparison and a phased roadmap. For a cost review only, we deliver a spending breakdown, savings recommendations and a prioritized action list. A comparison of the models is on the How we work page.
