Cloud Architect
OCEAN+ profile for Cloud Architect: high Openness to emerging paradigms, extreme Conscientiousness in cost decisions, and Extraversion to influence without authority.
What does a Cloud Architect do?
- Designs complete cloud architectures defining compute, data, networking, and security
- Audits and optimizes cloud spend by aligning infrastructure with real demand
- Defines reference standards and patterns that development teams implement
- Evaluates emerging services and paradigms, deciding which to adopt and when
- Plans migrations of legacy systems to the cloud while minimizing risk and downtime
- Presents architecture decisions and their costs to the CTO and business stakeholders
Ideal OCEAN+ Profile
Active exploration of emerging cloud services and cutting-edge architectural patterns
Rigor in designing architectures that balance cost, availability, security, and scalability
Executive presence to defend architecture decisions to the CTO and business stakeholders
Balance between technical firmness on critical decisions and openness to feedback from development teams
Resilience under difficult trade-offs, irreversible decisions, and cloud cost pressure
Sets standards and processes for other teams but operates at a strategic-conceptual level with some flexibility; doesn't follow rigid operational routines
Strengths and Red Flags
Strengths
- Designs cloud architectures that balance cost, performance, and resilience
- Cross-team technical influence that aligns multiple teams on platform decisions
- Long-term vision that anticipates future scalability needs
- Translates business requirements into technical architecture decisions
Red Flags
- Designs oversized architectures that maximize technical complexity
- Resists revisiting decisions when the business or context changes
- Disconnected from the development teams who will operate the architecture
- Optimizes technical metrics without considering the real cost of the solution
What does a successful Cloud Architect do?
The behaviors that separate top performers from average in this role, and the OCEAN+ profile dimension that explains them.
Questions the legacy sizing of each service instead of assuming it reflects real demand
OpennessHigh Openness detects that much of cloud spend is accumulated fear, not actual need
Backs every architecture decision with a monthly cost estimate and its underlying assumptions
ConscientiousnessConscientiousness in this range treats budget as just another design requirement, not a later surprise
Goes team by team defending the proposed architecture before formalizing it
ExtraversionModerate Extraversion builds buy-in privately so the public decision already has allies
Signs off on hard-to-reverse decisions after analyzing the risk, without postponing them indefinitely
Emotional StabilityEmotional Stability avoids the paralysis that in architecture costs more than a correctable mistake
Listens to objections from the teams who will operate the design and adjusts the non-essential parts without giving up the structural ones
AgreeablenessThe mid-range Agreeableness distinguishes between feedback that improves the design and pressure that degrades it
Requirements and Skills
- Deep experience designing and operating workloads on at least one major cloud provider
- Mastery of infrastructure as code and of cloud networking and security
- Understanding of cloud cost models and optimization practices
- Prior background in software engineering or infrastructure at scale
- Architect certifications from AWS, Azure, or GCP are common for this role

Illustrative Example
60% reduction in cloud costs with no performance impact
A Cloud Architect with Openness 84 and Conscientiousness 82 was hired to audit a cloud architecture costing $180k per month. Their high Openness led them to question assumptions: half of the high-cost services were over-provisioned out of fear, not real demand. Their Extraversion of 50 was enough to convince the development teams to migrate to spot instances and serverless without resistance. Within three months, costs dropped to $72k per month with zero availability incidents.
