All Rights Reserved. 11 Key Value Props for ScaleArc in the Cloud Enables simple application migration −Move enterprise workloads to the cloud with no app changes −Aggregate smaller cloud database instances to behave like one large server Provides high-availability solutions with auto failover −Within one locale or across regions/availability zones Delivers high-performance – for cloud and hybrid deployments −No performance compromise for apps in the cloud −Supports app in the cloud, database on prem Solves future scaling issues −Scale up and scale out without any app modifications

All Rights Reserved. 13 Top Use Cases – Business Perspective (Sales Rep) #1 – Help me use what I am paying for Use both primary and failover database servers (database load balancing) #2 – Stop my app from locking up during database failover Leverage auto failover without having to reboot app servers #3 – Help me scale out Simply add another database server to the pool to get more capacity #4 – Speed up my slow database Split read vs. write queries and cache various reads

© 2014 ScaleArc. All Rights Reserved. 14 Top Three Use Cases – Technical Perspective (SE) #1 – Continuous application availability Customers have implemented failover, but it leaves the app in shambles – ScaleArc enables the app to survive a database failover #2 – Visibility ScaleArc exposes the query request/response relationship between the application and the database, especially critical for cloud deployments #3 – Performance ScaleArc’s connection multiplexing, connection management, authentication offload, caching, and seamless failover speed throughput 14
