SIOS has been selling high availability clusters for over 20 years. In that time, we have become experts in enterprise applications. We have a keen understanding of the amount of risk customers are willing to take when servicing their customer's most critical application needs. But even we were surprised by the speed at which enterprises of all sizes have decided to migrate their business critical enterprise applications to the public cloud, including Amazon, Azure, Google, and others. We conducted a survey recently to understand more about this trend. We found that out of the respondents to our survey, 56% are operating Oracle workloads, 49% are running Microsoft SQL Server, and 28% have SAP/HANA in production.

The amount of risk hasn't changed, but enterprises have gained more confidence in cloud platforms and the associated tools that can keep their applications safe and running at 99.99% availability. Even though we inherently knew that occasional and regular performance issues in applications are the norm, 98% of respondents confirmed that this is what they, in fact, experience. When these issues occur, respondents state that it usually takes between 3-5 hours to identify the cause and correct the issue and 2-4 tools to do so.

The survey showed that most (86%) organizations understand the need for high availability and use some kind of clustering or high availability solution. Out of those that have high availability, organizations have reported on the reliability of these systems with 95% seeing occasional failure in the underlying high availability services that support their mission-critical applications.

That means that even though they have proactively protected their applications, the very protection they have applied is not reliable enough. These issues can be even more pronounced in the cloud. The need to control application environments is a key reason why many workloads remain on-premises for many of the respondents to the survey (60%). The biggest migration to the cloud is among small companies, where more than half (54%) intend to be running more than 50% of their business-critical applications in the cloud by the end of 2018. Even though large companies were moving more slowly to the cloud, 46% plan to have 50% or more of their applications in the cloud by 2018.

The fact that mission-critical applications, like SAP HANA, SQL Server, and Oracle are happening now is a strong testament of the sophisticated tools available to ensure the high availability of applications in the cloud. This is great news and a big win for enterprises, cloud providers, and application vendors who can look toward proven high availability products like SIOS Protection Suite for Linux to maintain control over their availability and performance in an efficient and cost-effective way in the cloud.
