IBM to Acquire Green Hat

IBM today announced a definitive agreement to acquire Green Hat, a leader in software quality and testing solutions for the cloud and other environments. Financial terms were not disclosed.

Founded in 1996, Green Hat is jointly headquartered in London, England and Wilmington, Delaware. Green Hat helps customers improve the quality of software applications by enabling developers to leverage cloud computing technologies to conduct testing on a software application prior to its delivery. Historically, to run simulation testing on a software program, a development team must construct an actual testing lab made up of both hardware and software. This time consuming and labor intensive process has become even more compounded with the short development cycle needed to compete in rapidly expanding markets such as those for smart phones and tablets. By using Green Hat’s solutions, a virtual test environment can be set up in a matter of minutes versus weeks, and for a fraction of the cost.

According to recent industry reports, software testing represents more than 50 percent of overall development costs, and testing teams often spend upwards of 30 percent of their time managing the complexity of the test environment.(1) Green Hat creates a virtual environment that simulates a wide range of IT infrastructure elements, without the constraints of hardware or software services. This continuous test environment enables developers and quality professionals to test software earlier and more frequently throughout the software development lifecycle.

Upon the acquisition close, Green Hat will join IBM’s Rational Software business. When combined with the IBM Rational Solution for Collaborative Lifecycle Management, developers and testers can achieve unprecedented levels of efficiency, effectiveness, and collaboration while delivering quality software to their business. IBM and Green Hat will help customers maximize continuous integration of an application, including creating virtual protocols, message formats, services, customization and engagement with third-party software. Development teams can avoid scrap and rework and dramatically reduce costly delays while achieving greater business agility and accelerating the delivery of software applications.

“This acquisition extends IBM’s leadership in driving business agility and software quality by changing the way enterprises can manage software development cost, test cycle time and risk,” said Kristof Kloeckner, General Manager, IBM Rational. “Together, we offer the most complete solution available today for agile software development and testing, with flexible options such as the cloud. Green Hat’s application virtualization capabilities will help our customers accelerate their delivery of business critical software.”

“We’ve been focused on transforming our customers’ software development processes through innovative testing and quality improvements,” said Peter Cole, CEO, Green Hat. “We are looking forward to bringing Green Hat’s innovative application virtualization and continuous integration testing expertise to IBM customers who have a growing business need to better manage their complex testing environments.”

The Green Hat software testing solutions also will be offered through IBM Global Business Services’ Application Management Services (AMS). IBM AMS provides strategy, design, implementation, testing and managed services for application virtualization to accelerate customer results.

Green Hat is an automated testing technology leader, operating worldwide with a Global 2000 customer base. Green Hat makes automated testing simple for complex systems relying on Cloud, Web Services, messaging, SOA (Service Oriented Architecture), ESB (Enterprise Service Bus), BPM (Business Process Management), CEP (Complex Event Processing), SAP and other distributed technologies. Their diverse range of customers includes prestigious representation in financial services, telecommunications, healthcare, transportation and the energy industry.

Taxonomy Notes:

IDC defines a Disk Storage System as a set of storage elements, including controllers, cables, and (in some instances) host bus adapters, associated with three or more disks. A system may be located outside of or within a server cabinet and the average cost of the disk storage systems does not include infrastructure storage hardware (i.e. switches) and non-bundled storage software.

The information in this quantitative study is based on a branded view of the disk storage systems sale. Revenue associated with the products to the end user is attributed to the seller (brand) of the product, not the manufacturer. Original equipment manufacturer (OEM) sales are not included in this study. In this study, Hitachi Data Systems (HDS) sales do not reflect their OEM sales to Sun Microsystems and Hewlett-Packard.

IDC’s Worldwide Disk Storage Systems Quarterly Tracker is a quantitative tool for analyzing the global disk storage market on a quarterly basis. The Tracker includes quarterly shipments and revenues (both customer and factory), Terabytes, $/Gigabyte, Gigabyte/Unit, and Average Selling Value. Each criteria can be segmented by location, installation base, operating system, vendor, family, model, and region.


Storage Virtualization Whitepapers

IBM XIV with VMWare for Optimized Storage-Server Virtualization

This whitepaper discusses the many challenges of a total virtualized solution in light of the integration of virtualized servers and virtualized storage. It reviews the complementary technologies of the VMware and IBM XIV® Storage System environments, while highlighting IBM XIV features that address the different issues. Real-world use cases provided at the end of the document illustrate IBM XIV server-storage virtualization success and benefits. After reading this paper, you will have a clear understanding of the different factors involved in achieving an effective virtual environment and how to address them using the IBM XIV Storage System.

Today’s virtualization technology is transforming business. Whether the virtualization goal is to consolidate servers, centralize services, implement disaster recovery, set up remote or thin client desktops, or create clouds for optimized resource use or new revenue streams, companies are increasingly virtualizing their environments.

Organizations often deploy server virtualization in the hope of gaining economies of scale in consolidating underutilized resources to a new platform. It’s important to remember that storage is the chief component underlying an enterprise IT system; therefore, equally crucial to a server virtualization scenario. Many who have implemented server virtualization but neglected to take storage into account find themselves facing common challenges of uneven resource sharing, and of performance and reliability degradation.

So what is the right storage for achieving a complete, complementary virtualized infrastructure? What storage system features will make the most of a virtualized server environment?

The IBM XIV® Storage System, with its next-generation grid architecture, automated load balancing, and exceptional ease of management, provides best-in-class virtual enterprise storage for virtual servers. IBM XIV reduces the overall footprint of the storage architecture as VMware reduces the server infrastructure. IBM XIV end-to-end support for VMware solutions, including vSphere and vCenter, provides hotspot-free server-storage performance, optimal resource use, and an on-demand storage infrastructure that enables the simplified growth key to meeting enterprise virtualization goals. Together, IBM XIV and VMware provide the best consolidation, performance, resilience, and usability for virtual infrastructures.
