In spite of recent advances in computing, many core business processes are batch-oriented running on Mainframes. Annual Mainframe costs are counted in 6+ figure Dollars per year, potentially growing with capacity needs. In order to tackle the cost challenge, many organizations have considered or attempted multi-year mainframe migration/re-hosting strategies. Traditional approaches to Mainframe elimination call for large initial investments and carry significant risks – It is hard to match Mainframe performance and reliability. Using Hadoop, Sears/MetaScale developed an innovative alternative that enables batch processing migration to Hadoop, without the risks, time and costs of other methods. This solution has been adopted in multiple businesses with excellent results and associated cost savings, as Mainframes are physically eliminated or downsized: Millions of dollars in savings based on MIP reductions have been seen – A reduction of 200 MIPS can yield $1 million in annual savings. MetaScale eliminated over 900 MIPs and an entire Mainframe system for one fortune 500 client. This presentation illustrates reference architecture and approach successfully used by MetaScale to move mainframe processing to the Hadoop platform without altering user-facing business applications.

For many organizations, the transition to DevOps starts small, often with a single team delivering new innovation — typically writing the tool chain as well as the application. This creates pockets of success, but reaping the full benefits of a DevOps practice means replicating these practices enterprise-wide. Not an easy task. Through its research, Forrester has identified 3 key steps for breaking down organizational silos and implementing a widespread DevOps initiative. In this on-demand webinar, guest speaker Robert Stroud, principal analyst at Forrester, joins Puppet for a webinar to share these practices and explore: • Trends in DevOps adoption — how many companies really have it figured out, which industries are leading the charge, and where do you fit in? • The role of senior leaders in a DevOps initiative, and why transformation is in their best interest. • How infrastructure automation and configuration management solutions lay the foundation for DevOps practices. • How to select the right tools to support your DevOps transformation.

The exploding API economy, combined with an advanced analytics market projected to reach $30 billion by 2019, is driving a market demand to expose more data from APIs. Business analysts, data engineers, and data scientists have been getting left behind in existing API strategies. This is because many APIs are designed to integrate with applications to extend functionality, however these data workers are looking for APIs that facilitate direct data access to support analytics. Data APIs are specifically designed to provide that frictionless data access experience to support analytics across standard interoperable interfaces such as OData (REST) or ODBC/JDBC (SQL). Consider expanding your API strategy to service the developers in this $30 billion market.

IT organizations are under continual pressure to develop and deliver high-quality applications – at speed - in order to provide key competitive advantage for their company. They’ve adopted Agile and DevOps practices. But particularly for large organizations with complex application portfolios or compliance pressures, these practices have yet to fulfill the promise of enhancing an organization’s ability to continually deliver customer value. Agile has improved development and test; and DevOps has streamlined getting code into production. But these advances have been localized improvements; to get to the next step software delivery leaders must take a more holistic approach to improving the entire lifecycle. In this webinar guest speaker, Forrester Senior Analyst Christopher Condo will present his analysis of practices used in modern application delivery and will describe how creating an integrated value stream can help organizations regain their focus on the delivery of customer value.

If your enterprise is focused on continuously improving quality, velocity and efficiency, you’re going to win against those that aren’t. Driving improvements on the mainframe, and in turn throughout the business, requires the transformation of three things: culture, processes and tools. In other words, changing mindsets, implementing modern practices (Agile, DevOps, CI/CD) and replacing outdated technology. Mainframe source code management is currently a critical area in need of modernization and should be one of the initial tooling changes organizations make when setting out to improve mainframe systems delivery. During this session, Compuware specialist Lars-Erik Berglund shares the challenges organizations face with mainframe source code management and what you can do to overcome those.

Automation, visibility and integration are key components of successful DevOps and Continuous Delivery transformations. They enable teams to be more productive, in part, by reducing manual steps and hand-offs. But if you're like most large, enterprise organizations, these components also need to apply to your mainframe to get the most from your IT investments. The mainframe’s historically siloed, slow, waterfall culture can often conflict with, and constrain, IT from meeting the needs of the business. Enter Compuware and XebiaLabs. Together, we mainstream the mainframe to break down organizational silos and create a single, unified DevOps culture. During this webcast, Compuware Product Manager Steve Kansa and XebiaLabs VP of Products Tim Buntel show a day in the life of a fully integrated enterprise DevOps team and how the mainframe is included in a variety of modern software delivery scenarios.

Why should you care about CPU utilization? Intuitively, we all know it’s a measure of how “busy” our system is, and we know that this affects how fast things will run. We also know that we don’t want utilization to be too high, but unlimited capacity is certainly not free. What exactly is “too high”? 80%, 90%, 99%? What is an accurate measurement and how current is it? During this on-demand webcast, we dive into issues affecting utilization and the key role that Compuware ThruPut Manager plays in optimizing your batch workloads to keep your machine running at the performance sweet spot.

The action of the next cyber saga takes place in the mystical lands of the Asia-Pacific region, where the main characters began their digital activities in the middle of 2021 and qualitatively strengthened it in 2022. Corporate espionage, document theft, audio recordings, and data leaks from messaging platforms were all a matter of one day for Dark Pink. Their geographical focus may have started in the Asia-Pacific region, but their ambitions knew no bounds, targeting a European government ministry in a bold move to expand their portfolio. Their victim profile was as diverse as a UN meeting, targeting military organizations, government agencies, and even a religious organization. Because discrimination is not a fashionable agenda. In the world of cybercrime, they serve as a reminder that sometimes the most serious threats come in the most unassuming packages with a pink bow.

The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions. About the author With two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing.

Systems of Engagement depend on services offered by mainframe applications. In many cases, those services in turn depend on older “legacy” applications. Organizations are gradually, incrementally, modernizing these applications by breaking them down into modular services. As they do, they modify the old applications to use the services as well; the services don’t just “wrap” the old application, they take over part of it. Services may have their own data, or they may come to own some of the corporate data. These service also are used to intermediate the interactions between legacy applications which helps to reduce complex inter-application dependencies.
