The Infrastructure as a Service (IaaS) Architecture solution covers the design, structuring and governance of cloud-infrastructure environments, with the formal definition of compute, storage and network components oriented to performance, security, availability and business-continuity requirements.

The architecture is structured to support corporate and critical workloads in public, private or hybrid cloud models, with logical segmentation, access controls, data-protection policies and resilience mechanisms aligned with the technical premises of the enterprise.

A3A Engenharia de Sistemas develops each architecture based on dependency mapping, service criticality and operational requirements, ensuring technical predictability, decision traceability and integration with local infrastructure and existing business systems.

Scope of Work

Architecture and Planning

  • Survey of workloads, dependencies and service requirements
  • Definition of the cloud model: public, private, hybrid or multicloud
  • Structuring of virtual networks, subnets and security domains
  • Planning of secure connectivity with on-premises environments
  • Capacity sizing for CPU, memory, storage and IOPS
  • Definition of resilience and high-availability policies
  • Structuring of backup and recovery strategies

Provisioning and Implementation

  • Provisioning of compute, storage and networking resources
  • Implementation of baseline templates and standard configurations
  • Integration with identity and access management mechanisms
  • Configuration of automation, orchestration and infrastructure as code
  • Interconnection with business systems and data repositories

Security and Technical Governance

  • Definition of logical segregation and least-privilege controls
  • Configuration of logging, auditing and technical traceability
  • Data-protection and encryption policies
  • Compliance alignment and hardening of the environment

Operations, Monitoring and Evolution

  • Monitoring of performance, availability and cost indicators
  • Operational governance routines and change management
  • Adjustment of capacity and elasticity policies
  • Evolution of the architecture according to new business demands

Applications and Environments

The solution is applicable to:

  • Corporate environments undergoing cloud migration
  • Hybrid and multicloud infrastructures
  • Digital transformation initiatives
  • Critical workloads that require resilience and governance
  • Technology platforms with elastic growth needs

The architecture is designed to ensure control, predictability and secure evolution of cloud environments that support business operations.

Standards and Compliance

The solution is developed according to best practices for cloud architecture, access governance, technical traceability, information protection and operational resilience, always aligned with the policies and risk profile of the enterprise.
