A client with the need to establish and provide Database as a Service (DaaS) capability has resolved that every database instance is provisioned and stationed inside its own VM. There can be occasions wherein there are 100 VMs running 100 databases. This is extremely inefficient, wasting a lot of expensive resources. Now the same number of database instances can be run on that number of containers, which in turn could run inside a few VMs. The result is huge cost savings. Another case study follows:

• Customer details: Swisscom is a Switzerland's leading telecom provider offering a range of enterprise and consumer services.
• The business challenges: This includes offering a reliable, easy-to-maintain DaaS to customers while achieving server density necessary to operate efficiently.
• The solution approach: Flocker by ClusterHQ provides the ability to programmatically manage persistent data for Docker containers stored in EMC ScaleIO.
• The business outcome: This solution has substantially increased the density of applications hosted per server, improved operational management of databases, and laid out a stimulating and sparkling platform for sustainable innovation in consumer and enterprise IT sectors.
