01 What happened
SAP introduces SAP HANA Cloud scale-out as part of SAP's Multi‑Dimensional Elastic Scaling strategy, a solution that extends memory capacity horizontally across multiple nodes, thereby enabling workloads that exceed single‑node limits।
02 Key details
- SAP HANA Cloud scale-out is a permanent horizontal scaling capability introduced by SAP under the Multi-Dimensional Elastic Scaling strategy, distributing a single HANA Cloud instance across one coordinator node and multiple worker nodes as a shared-nothing cluster.
- The coordinator node orchestrates query execution and manages cluster-wide operations; all nodes equally store data and process queries in parallel.
- Online flexible scaling lets users add or remove worker nodes and resize nodes to match memory and CPU requirements; changes remain transparent to applications without downtime.
- Migration tool support reduces manual effort for migrating existing SAP HANA Scale-Out systems to SAP HANA Cloud.
03 Why it matters
Scale-out completes the Multi-Dimensional Elastic Scaling strategy by addressing data that permanently exceeds single-node capacity, complementing vertical scaling and elastic compute nodes (ECNs), enabling very large in-memory capacity and high-performance compute with one logical instance.
04 Who it matters to
SAP HANA administrators and SAP developers.
