Database High Availability Simplified

Database High Availability in Public Clouds

SkyCluster is an engineered cloud system designed for database high availability. SkyCluster runs proven Oracle RAC database engine to deliver best-in-class active-active high availability in the cloud for the large ecosystem of enterprise applications running on Oracle Database.

  • Deploy new mission critical applications in the cloud.

  • Migrate existing databases.

  • Improve availability SLA for the databases already in the cloud.

Multi-cloud database high availability

One HA Platform for Multiple Clouds and On-Prem Environments

Compliance with local regulations, mergers, acquisitions, or simply lowering costs – there are multiple reasons why in future you may need to run your databases in a different public cloud or  in a private data center. SkyCluster allows portability between multiple IaaS clouds and private data center environments with minimal changes to the database stack.


  • Public clouds: AWS, Azure, GCP, OCI, and more coming. Commercial, government, and restricted regions.
  • Private cloud stacks: Azure Stack, AWS Outpost, VMware Cloud Director, Red Hat OpenShift
  • Traditional data center: bare-metal or virtualized with VMware, Oracle VM, or KVM (using FlashGrid Storage Fabric)

SkyCluster Architecture

SkyCluster is delivered as a fully integrated Infrastructure-as-Code template. It takes only a few mouse clicks to configure and deploy SkyCluster to your IaaS cloud account. With large VM or bare-metal instances, SSD storage, and multi-AZ, SkyCluster enables performance and HA matching or even exceeding most on-premises database deployments.

SkyCluster components:

  • IaaS VM or bare-metal instances
  • Persistent or local SSD disks
  • FlashGrid Storage Fabric software
  • FlashGrid Cloud Area Network software
  • Oracle Grid Infrastructure software
  • Oracle RAC database engine

24/7 Support for Entire Infrastructure Stack

SkyCluster is delivered as a pre-integrated cloud system using customizable Infrastructure-as-Code templates. FlashGrid validates and supports the entire infrastructure stack including Oracle Clusterware and ASM. Deep database and IaaS cloud expertise ensures smooth database operation during the entire life of your applications.

“We had to migrate dozens of mission critical Oracle RAC databases from Exadata to AWS with FlashGrid SkyCluster, and were able to do it without sacrificing performance or availability.”

Rama Kolli, Sr. Director – Database Management, S&P Global Ratings

“FlashGrid SkyCluster provides us all elements needed for running our mission-critical Oracle databases in Azure: storage and networking software, deployment automation, and 24x7 support.”

Jay Wilder, Sr. Director of Software Engineering, Nuance Communications

“With FlashGrid and AWS we can now deploy a new application within two weeks instead of six months, without compromising our availability SLA.”

David Urban, VP Operations, Aria Systems

“SkyCluster for Azure proved to be a reliable solution that is easy to implement and support for us as a systems integrator.”


“With our new virtualized RAC running on FlashGrid architecture we do a 125GB full table scan in 6 seconds. That is an 11x improvement over our previous setup.”

Sam Shiel, Oracle DBA, Simplyhealth

“Implementing Oracle RAC with FlashGrid in AWS is an important milestone in Digital Virgo’s cloud journey.”

Mikolaj Klimek, Deputy Director IT Operations and Infrastructure, Digital Virgo
