IaaS (Infrastructure as a Service) is a cloud model that provides virtualized compute, storage, and networking that the customer manages. Cloud+ covers cloud service models in the architecture domain.

PaaS

PaaS (Platform as a Service) is a cloud model that provides a managed platform for building and running applications without managing the underlying infrastructure. Cloud+ covers it among cloud service types.

SaaS

SaaS (Software as a Service) is a cloud model that delivers fully managed applications over the internet. Cloud+ covers SaaS alongside IaaS and PaaS in cloud architecture.

High availability

High availability is a design goal of keeping a service operational with minimal downtime through redundancy and failover. Cloud+ covers designing for high availability in the architecture domain.

Load balancing

Load balancing distributes incoming traffic across multiple resources to improve availability and performance. Cloud+ covers load balancing in cloud networking design.

Autoscaling

Autoscaling automatically adjusts the number of running resources to match demand. Cloud+ covers autoscaling for scalability and cost optimization in cloud operations.

Infrastructure as code

Infrastructure as code (IaC) is the practice of provisioning and managing infrastructure through machine-readable templates. Cloud+ covers IaC in deployment and DevOps fundamentals.

CI/CD

Encryption

Encryption protects data by converting it into a form readable only with a key, both at rest and in transit. Cloud+ covers encryption and key management in the security domain.

Key management

Key management is the handling of cryptographic keys across their lifecycle, including generation, rotation, and storage. Cloud+ covers key management as part of cloud data security.

Disaster recovery

Disaster recovery is the set of strategies for restoring service and data after a major failure, measured by RTO and RPO. Cloud+ covers backup and disaster recovery in operations.

Cloud migration

Cloud migration is the process of moving workloads and data to the cloud using strategies such as rehost, replatform, and refactor. Cloud+ covers migration in the deployment domain.
