Migration to cloud has cut database costs and simplified shared storage but still needs lower latency

The best features FlashGrid Cluster for Oracle RAC offers include shared storage, which is critical because for on-premise Oracle high availability clusters, I do not need FlashGrid. When I migrate to the public cloud, I need FlashGrid to provide that shared storage. It is easy to migrate from on-premise to cloud because the Oracle architecture does not change; the only difference is that in the public cloud, shared storage block was not available, but FlashGrid provides that feature to the Oracle RAC cluster. FlashGrid Cluster for Oracle RAC has positively impacted my organization cost-wise because by migrating to the cloud from my on-premise data center, I could consolidate the price structure for my storage and compute needs. Oracle RAC was the bottleneck for that because previously, without FlashGrid, I could not configure Oracle RAC in the public cloud, but with FlashGrid, I managed to consolidate costs for Oracle RAC infrastructure in the cloud. After migrating with FlashGrid, I have a substantial presence of Oracle RAC clusters in my data centers, around 50 RAC clusters across the U.S., and each was costing around $100,000 per year per cluster. However, I was able to migrate 25 of those clusters to the public cloud using FlashGrid, and the cost was reduced to $50,000 for those clusters, meaning I saved $50,000 per annum for the 25 instances. After installing and configuring FlashGrid in AWS cloud, I was able to reduce the storage cost substantially compared to my on-premise data center storage. I saved $50,000 per Oracle RAC cluster per annum using FlashGrid, which includes both storage cost, compute cost, and also manpower cost.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"I saved $50,000 per Oracle RAC cluster per annum using FlashGrid, which includes both storage cost, compute cost, and also manpower cost."

"The stability and performance of the cluster during testing were impressive."

"Some of the advantages, are it can give you the ability to choose."

"I would recommend this solution to others, we have used it for a long time and it has been reliable."

"The product is stable."

"Business continuity is much better, due to the possibility of patching/upgrading systems without interruption of services."

"But once it is done, it will perform very well."

"The reliability is pretty good."

"The solution switches over to another server in case the server goes down."

"It's scalable, highly available, and is agile to handle workloads."

Cons

"There is room for improvement in the area of migration or integration with existing on-premises infrastructure."

"One weakness is that there might be performance degradation once I install Oracle RAC in the public cloud using FlashGrid; that is one weakness I have encountered after migrating to the public cloud with FlashGrid."

"There are times when we do the system security updates and have to restart the server which is difficult because we need to wait until the end of the day or when working hours are finished. There are service updates that have a requirement to restart the system and it is not convenient."

"The product should be less dependent on network configuration."

"They could drop the price or improve the cost of the hyper-converged component of it all. Right now, licensing is expensive and complex."

"Technical support isn't as responsive as I'd like."

"The tool's pricing is high."

"The stability is good, except for when something crashes or shuts down unexpectedly, then it can be a bit difficult to reestablish the service in a stable state."

"The standard, non-enterprise technical support could be improved."

"We are currently looking for another solution because, in many industries, such as eCommerce, they operate 24 hours a day seven days a week and this solution has some downtime which our customers do not like."

Pricing and Cost Advice

Information not available

"I would rate the solution's pricing an eight out of ten."

"So if you acquire the Windows server license, you will also get all of the Windows services licenses."

"The functionality is included in Windows Server licences."

"We are on an annual license to use this solution."
