Architectural Design & Specialization

· Tiered Architecture: Organizing systems into functional layers, such as separate web, application, and database servers.

· Specialized Infrastructure: Provisioning servers based on specific workloads (e.g., separating database servers from web servers) to avoid resource contention.

· Component Distribution: Using multiple app servers to handle user load and separate database nodes forread/write operations (e.g., CStore nodes in analytics).

· Multi-Region/Global Setup: Distributing infrastructure across multiple geographic regions to reduce latency and enhance disaster recovery.

Scalability & Performance

· Horizontal Scaling: The ability to increase capacity by adding more servers (scale-out) rather than just upgrading a single machine.

· Load Balancing: Implementing load balancers (e.g., Nginx) to distribute traffic efficiently across multiple servers, ensuring no single server becomes a bottleneck.

  • Caching: Using distributed caching mechanisms to store frequently accessed data across nodes, improving responsiveness**.**

 

Reliability & High Availability (HA)

  • Redundancy & Failover: Implementing N+1 or N+N redundancy for power and cooling in multi-node setups to ensure continuous operation, even if a server fails.
  • Active-Passive Setup: Using secondary, passive servers that take over immediately if the primary server goes offline.
  • Data Replication: Ensuring consistency across databases or file systems using replication mechanisms between parent and child servers.

 

Monitoring & Management

  • Granular Monitoring: Implementing monitoring tools to track the health, performance, and resource usage of each independent server in the cluster.
  • Centralized Management: Managing widely distributed systems from a central location, such as using an Operational Bridge Manager (OBM).
  • Automation: Using tools for automated deployment, configuration, and scaling (e.g., DevOps tools, container orchestration).

 

Security & Data Management

  • Isolation: Keeping sensitive data on backend servers that do not directly communicate with the internet (e.g., PCI-DSS compliance).

  • Secure Authentication: Managing user authentication across distributed services using secure protocols, such as token-based authentication or centralized identity management.

  • Data Partitioning/Sharding: Distributing data across multiple database instances to manage large volumes and improve query performance Security & Compliance

  • Ensure architecture compliance with secure boot and platform security principles

  • Collaborate with cybersecurity stakeholders to validate system hardening and trust chains

  • Integrate security considerations by design (defense‑in‑depth, least privilege, lifecycle security

 

Obsolescence & Sustainability

  • Identify and assess technology obsolescence risks
