Enterprise modernization

Accelerating DevOps for enterprise systems

Get more out of existing enterprise applications, infrastructure, and skills

If you use the power of IBM Enterprise systems to run your business, you almost assuredly use them for business-critical functions. These systems contain a wealth of information and business logic. However to remain competitive you need to integrate these systems of record with the new systems of engagement, particularly mobile devices and hybrid cloud applications.

To tackle the delivery of complex multiplatform applications, businesses are embracing DevOps, a software delivery approach that focuses on speed and efficiency without sacrificing stability and quality.

The IBM DevOps solution for System z and Power Systems can help you achieve dramatic improvements in speed, capacity and cost – providing fast-mover advantage to the business.

DevOps: Accelerating Enterprise Software Delivery

Delivering software is complex. Enterprise systems consist of multiple databases, subsystems, and services, built up over decades. Aligning teams to drive system changes is difficult, where even minor changes to critical systems may involve multiple parties from storage admins, to system programmers, to security personnel, to DBAs, to developers. Coordinating, integrating, and validating the work between stakeholders is often manual, leading to long cycle times and frequent defects. DevOps is an emerging trend aiming to speed and govern the delivery of complex software by increasing collaboration between operations and development teams. This session introduces Enterprise DevOps tools and practices and outlines an adoption paths for Mainframe and Power Systems DevOps including: collaborating on delivery across multiple roles and teams, provisioning of $0-MIPs z/OS test environments, and implementing an automated integration testing system.

#290 Simplify testing with virtual CICS programs with IBM Rational Test Automation Solution (Green Hat)

There is wide-spread adoption of agile practices throughout the development lifecycle, including building and maintaining critical applications on the mainframe. Achieving agility here is helped through the use of automated testing and techniques like Service Virtualization which can shorten the delivery cycle, and improve application quality. IBM Rational Test Automation Solution now enables service virtualization and automated integration testing for CICS applications, scaling down and simplifying the required CICS test region configuration and MIPS requirements.

Continuous integration and test virtualization in a mainframe world

Poor software quality is blamed for more major business problems than any other man-made product, and results in over 500 billion dollars of losses worldwide. Improving application quality is a high priority in virtually every industry. But traditional testing methods have become too costly and impractical to keep up with business demands due to the increasingly complex web of hardware, software and services. By automating the building and testing of z/OS application code in isolated environments using virtualized services, the IBM Continuous Integration Solution for System z helps significantly improve software quality while reducing delivery time and costs.
