Senior Platform/Solution Architect – Capacity Planning, Performance & Cloud Infrastructure Architecture Role Purpose The Senior Platform/Solution Architect – Capacity Planning, Performance & Cloud Infrastructure Architecture is responsible for translating business demand, application traffic and workload characteristics into quantifiable infrastructure requirements: across microservices, Kubernetes/OpenShift, cloud and on-premises environments. The role provides the technical capability to determine CPU, memory, pod/replica, node, cluster, database, storage and network requirements: while ensuring performance, scalability, resilience, availability and cost efficiency. Core Responsibilities: Lead capacity planning and infrastructure dimensioning for applications, platforms and microservices-based services. Translate business growth, transaction volumes and traffic forecasts into infrastructure capacity requirements. Develop quantitative workload models covering normal, peak, burst and exceptional traffic conditions. Determine appropriate CPU, memory, pod/replica, node and cluster requirements: for application services. Develop capacity forecasts and infrastructure roadmaps covering short-, medium- and long-term demand. Ensure capacity plans support availability, resilience, disaster recovery and business continuity requirements. Provide architecture and capacity recommendations for both cloud and on-premises environments. Review existing environments to identify over-provisioning, under-provisioning, bottlenecks and capacity risks. Microservices Capacity Planning & Dimensioning: Assess resource consumption and performance characteristics of individual microservices. Determine minimum, normal and maximum pod/replica requirements: based on workload and service-level objectives. Define CPU and memory requests and limits for containers. Assess horizontal and vertical scaling requirements: and define appropriate scaling policies. Determine node density, resource utilisation and cluster capacity requirements. Account for service-to-service communication, platform overhead and infrastructure reserve capacity. Establish repeatable sizing methodologies for new applications and services. Validate sizing assumptions through performance and capacity testing. Capacity Planning Parameters & Metrics: Define and maintain standard parameters for application and infrastructure capacity planning. Analyse requests per second (RPS), transactions per second (TPS), concurrent users, sessions and transaction volumes. Analyse average, peak and burst traffic and associated growth patterns. Assess CPU utilisation, CPU consumption per transaction, memory utilisation, memory peaks and application heap requirements. Assess pod counts, replica requirements, scaling thresholds and scaling response times. Determine node CPU, node memory and allocatable cluster capacity. Assess database TPS, connections, CPU, memory, IOPS and throughput. Assess storage capacity, IOPS, throughput and growth. Assess network bandwidth, latency and packet rates. Factor in high availability, N+1/N+2 resilience, disaster recovery, growth headroom and operational reserve. Performance Engineering: Lead performance engineering and capacity validation for critical applications and platforms. Define and oversee load, stress, endurance, spike, scalability and capacity testing. Analyse throughput, response time, latency, concurrency and resource utilisation. Identify application, platform, database, storage and network bottlenecks. Establish performance baselines and capacity thresholds. Use performance test results to validate CPU, memory, pod, node and cluster sizing. Work with engineering teams to optimise resource consumption and application performance. Observability & Data-Driven Capacity Planning: Use production telemetry and historical performance data to develop evidence-based capacity models. Leverage metrics, logs, traces and APM data to understand workload behaviour. Use monitoring and observability platforms such as Prometheus, Grafana, OpenTelemetry, Dynatrace, AppDynamics or equivalent tools. Correlate traffic, application performance, pod utilisation, infrastructure consumption and database performance. Establish capacity thresholds, early-warning indicators and capacity risk dashboards. Use trend analysis and forecasting to identify future infrastructure requirements: before capacity constraints occur. Architecture Governance & Standards: Establish standard capacity planning and dimensioning methodologies across the organisation. Define architecture principles, sizing standards, resource profiles and capacity governance processes. Review and approve application capacity models and infrastructure sizing proposals. Ensure new services meet defined scalability, availability, performance and capacity requirements: before production deployment. Establish governance for capacity reviews following major releases, traffic changes or architectural changes. Maintain architecture documentation, capacity assumptions, sizing models and decision records. Key Deliverables Application Capacity Model Microservices Dimensioning Model CPU & Memory Sizing Model Pod/Replica Sizing Model Kubernetes/OpenShift Cluster Sizing Database Capacity Model Storage & IOPS Capacity Model Network Capacity Model Cloud Infrastructure Sizing On-Premises Infrastructure Sizing Three- to Five-Year Capacity Forecast Peak/Event Capacity Plan Performance Test Strategy and Capacity Validation Report Capacity and Performance Dashboard Infrastructure Bill of Materials (BoM) Cloud Cost/TCO Model Capacity Headroom and Risk Assessment Experience: & Professional Profile Typically 10–15+ years of experience: across solution architecture, platform architecture, cloud infrastructure, capacity planning, performance engineering or related disciplines. Proven experience: designing and dimensioning large-scale distributed systems and microservices platforms. Strong experience: with Kubernetes/OpenShift and containerised application environments. Hands-on experience: with cloud and on-premises infrastructure architecture. Demonstrable experience: in capacity planning, workload modelling, performance engineering and infrastructure forecasting. Experience: with large-scale, high-availability, transaction-intensive environments is highly desirable. Experience: in telecoms, financial services, digital platforms or other high-volume technology environments is advantageous.
