Organisations around the world are recognising the increasing role that technology plays in driving change as they shift investments from infrastructure maintenance towards new projects, such as cloud, data analytics and mobile applications. To remain competitive, they must constantly adapt and respond with increased speed to deliver new services through multiple channels to customers, partners and employees. To capitalise on this opportunity, organisations must be able to tap into their valuable data and energise applications without going over budget while keeping everything protected and secure to reduce organisational and reputation risk. This requires an optimised infrastructure that is integrated, agile, trusted and secure.

The newest member of the IBM® zEnterprise® System family is the IBM zEnterprise BC12 (zBC12). Designed as an entry point for enterprise computing it embodies the same innovation and value, flexible growth options, industry-leading virtualisation, trusted resiliency, secure cloud, enterprise mobility and operational analytics capabilities as the massively scalable IBM zEnterprise EC12. The zBC12 delivers a lower and more granular cost structure with significant improvements in packaging, performance and total system scalability over prior generations.
