While the data growth rate, number of database instances, and number of platforms that each DBA must support has not changed radically in the last few years, the database infrastructure has become more complicated. Two key factors are at play in the increasing complexity. Cloud has evolved into a significant platform for database management and non-relational databases, including NoSQL databases, have gained a notable foothold in the corporate environment, according to a recent survey of 285 IT managers and professionals, conducted by Unisphere Research.
According to the study, titled “Achieving Your 2018 Database Goals Through Replication: Real-World Market Insights and Best Practices: 2018 IOUG Special Report on Database Replication Trends,” organizations are increasingly turning to real-time database replication as an essential element within an availability and continuity architecture stack.
The survey found that 63% of or organizations cited availability of applications (no downtime) as their most important database concern, followed by performance (49%), database security (35%) and upgrading (13%).
The survey found that databases continue to expand in size and complexity, while at the same time, more enterprises are turning to cloud-based resources to keep information highly available. Availability and performance are the most important services that data shops can deliver. And, increasingly, keeping data highly available is no longer a simple matter of backing up one database with an up-to-the-second copy of another.
The survey also looked the depth to which cloud computing is being adopted. Cloud is a key factor—and enabler—of enterprise data replication strategies going forward. While most major enterprise databases are still on premise, this is likely to change soon. In 5 years’ time, a majority of respondents expect to have their major databases running in cloud environments.
Data replication is considered a critical solution that supports infrastructure and data services by virtually all enterprises. Eighty-nine percent of respondents to the Unisphere study reported employing data replication to keep essential data available to users and customers. Disaster recovery is the most visible use case, but the offloading of non-critical workloads and support of data integration is also facilitated through replication.
When asked about the business drivers for supporting a robust replication initiative, disaster recovery—and by extension, business continuity—was shown to be a leading factor, cited by 83% of respondents.
