Launch the campaign first. Then add components and observe the difference under the same load.
CONSULTANT'S NOTE
The outage affects the first application server. A second server, if added, continues serving requests.
Simulation assumptions
Each application server handles 70 jobs/step; the database handles 50. Cache reduces database workload by 55%. The queue holds 240 requests. The base setup uses 3 illustrative resource units; each added component uses 1. Steps are not real seconds, and units are not real costs. A queue does not add capacity; this is not a universal architecture recommendation.

Software Architecture Consulting
Design for today’s needs and tomorrow’s change.
We design software architecture around product behavior, quality expectations and the way your team works. System boundaries, data, service relationships and deployment need reasoned decisions.
For new products and existing systems, we focus on manageable change without unnecessary complexity.
What we deliver
A clear architectural framework for growing systems.
Architecture assessment
We review the existing system’s components, dependencies, data flows and critical pain points. We identify where the current structure may struggle with performance, maintenance and scale.
Architecture assessment
Risk and dependency map
Target architecture
We define how the system will be divided, where responsibilities begin and end, and how data and services relate. We shape the technical structure around both current needs and expected growth.
Target architecture
Data and service boundaries
Decisions and transition plan
We clearly document the reasoning, alternatives and effects of architectural decisions. We turn the sequence of changes into practical steps that protect the existing product.
Architecture decision records
Transition plan
The work in context
Not every system needs microservices.
Separating a module depends on independent delivery needs, data ownership and operational effort. Clear boundaries and responsibilities matter more than a technology label.
Defined boundaries
Each component has clear responsibilities and data ownership.
Reasoned choices
The reasons for rejected options are recorded alongside the selected approach.
Example architecture decision framework and illustrative image, not a client architecture.

Decision area
What we assess
Resulting decision
Module boundaries
What we assessWe assess which functions should stay together and which need to evolve independently.
Resulting decisionModule responsibilities, boundaries and communication are clarified.
Data ownership
What we assessWe determine which system will manage the data and how other components will access it.
Resulting decisionThe authoritative data source, access model and data consistency rules are defined.
Service continuity
What we assessWe plan how the system will behave when a service slows down, stops responding or becomes temporarily unavailable.
Resulting decisionTimeout, retry, error handling and monitoring decisions are established.
Illustrative architecture decision record. Technology and deployment choices follow the product’s requirements.
How we work together
Understand the present and sequence the target.
Deliverables and the working plan are defined around the needs of your project.
01
Clarify requirements
We define product functionality, expected load, data needs, integrations and continuity expectations.
OutputArchitecture requirements
02
Assess the existing structure
We review the code structure, data flows, services, dependencies and operating model. We identify strengths and areas that need change.
OutputCurrent state analysis
03
Define the target architecture
We compare alternatives against performance, scalability, maintenance effort and team structure, clarifying component boundaries and responsibilities.
OutputTarget architecture and decision records
04
Plan the transition
We phase changes according to risk, dependencies and priorities, planning testing, rollback and rollout steps together.
OutputPhased transition plan
Engineering in the details
Continuity is as much a part of architecture as performance.
Failure boundaries
We assess how the failure of one component affects others.
Data consistency
Ownership, synchronization and transaction boundaries are considered together.
Operational effort
Deployment, monitoring and maintenance are balanced against team capacity.
Common questions
Let's start with your questions.
Can you review an existing application?
Yes. We establish the scope by reviewing the existing code structure, services, data flows, dependencies and operating conditions. The review can cover the entire system or focus on a particular module, performance issue or growth need.
Do we have to move to a microservices architecture?
No. Microservices alone do not make an architecture better. We assess system size, team structure, deployment needs and operational effort to determine whether to retain, modularize or separate the existing structure.
Does the existing system need a complete rewrite?
Not always. A rewrite can bring substantial cost and transition risk. We first assess which parts can be retained, which need improvement and whether the transformation can be carried out in phases.
Does the engagement include development?
Yes, depending on the scope. Architecture consulting can be limited to assessment, a target structure and a transition plan, or it can also cover developing critical components, prototyping and implementing the transformation.
Can you anticipate where our system will struggle as it grows?
To a certain extent, yes. We can identify areas at risk by examining traffic, data volume, service dependencies, critical flows and current capacity. The aim is to understand both today’s performance and the point at which growth will require architectural change.
How do you document architectural decisions?
We record the reasoning behind important decisions, the alternatives considered, their effects and the chosen approach. This makes decisions understandable for new team members and future development, beyond the team’s collective memory.
Can you work with our existing team?
Yes. We evaluate architectural decisions with the technical team rather than leaving them as an external report. We bring existing knowledge into the process and help the team take ownership of practical decisions.
Can cloud infrastructure be part of the architecture engagement?
Yes. Alongside application architecture, we can assess deployment models, scaling, data services, monitoring and continuity needs. We choose technology according to the product’s requirements rather than a particular provider.
Are performance problems caused only by infrastructure?
No. Problems can arise in the data model, queries, application code, service communication, caching or different infrastructure layers. We therefore identify the actual cause before increasing capacity.
