Silicon Valley-based database infrastructure software maker ScaleArc has secured $5.33 million in its second round of institutional funding, which was led by Trinity Ventures, with earlier backer Nexus Venture Partners participating.

In addition, ScaleArc announced the appointment of Justin Barney, who previously ran sales divisions at companies like Citrix and Juniper Networks, as president and COO.

ScaleArc’s iDB software, which is available for MySQL, SQL Server, Oracle and Postgres database environments, offers real-time query analytics and control, instant horizontal scaling, caching, dynamic load balancing and more, all without any changes to existing applications or databases.

ScaleArc customers include e-commerce, SaaS, online gaming and digital media companies.
