They define all of the tasks and knowledge that an individual would need to have in order to successfully implement the product. This creates the foundation for the objectives and measurement criteria, which are the basis for the certification exam. The Middleware Certification item writers use these objectives to develop the questions that they write and which will appear on the exam. It is recommended that you review these objectives. Do you know how to complete the task in the objective? Do you know why that task needs to be done? Do you know what will happen if you do it incorrectly? If you are not familiar with a task, then go through the objective and perform that task in your own environment. Read more information on the task. If there is an objective on a task there is about a 95% chance that you WILL see a question about it on the actual exam. After you have reviewed the objectives and completed your own research, then take the assessment exam. While the assessment exam will not tell you which question you answered incorrectly, it will tell you how you did by section. This will give you a good indication as to whether you are ready to take the actual exam or if you need to further review the materials. Note: This is the high-level list of objectives.

Detailed Exam Objectives Section 1 - Cloud Computing Concepts and Benefits 1.1. Define the cloud computing business advantages. Cloud computing is the latest major evolution in computing. It is a paradigm where computing resources are available when needed, and you pay for their use in much the same way as for household utilities. Just as water is piped to your home and you pay for as much or as little as you use, cloud computing resources are available whenever needed and charges are based on how much you use them. When you turn it off, the water that you would have used is available for use by others and, in the same way, shared cloud resources can be used by others when not used by you. Widespread cloud computing is made possible by the Internet, and this is the most common way of accessing cloud resources. Intranets and dedicated networks are sometimes used too, in the case of a private cloud, for example. 1.1.1. Cloud computing provides the ability to make use of computing resources on an immediate basis, rather than a need to first invest time and skilled resources in designing and implementing infrastructure (hardware and middleware) and/or applications, and then deploying and testing it. This leads to faster time to value which may mean enhanced revenue, larger market share, or other benefits. 1.1.2. Describe how cloud computing can be a disruptive influencer 1.1.3. Describe the Business Drivers for adopting Cloud Computing 1.1.3.1. Agility 1.1.3.2. Innovation 1.1.3.3. New business models 1.1.3.4. Velocity 1.1.3.5. Self Service 1.1.3.6. Cost reduction 1.1.4. Define and classify systems in typical IT landscape into each category 1.1.4.1. Systems of Record 1.1.4.2. Systems of Insight 1.1.4.3. Systems of Engagements 1.1.5. Choose the target operating environment for system categorized as SOE, SOR, SOI, explain supporting rationale and business advantages 1.1.6. Define Two Speed IT, the characteristics of each and how would they co-exist 1.1.6.1. Industrialized Core 1.1.6.2. Agile Edge 1.1.7. Describe the top five benefits realized from Cloud Computing 1.1.7.1. Achieve economies of scale 1.1.7.2. Reduce CapEx by moving to OpEx 1.1.7.3. Improve access 1.1.7.4. Implement agile development at low cost 1.1.7.5. Leverage global workforce References;http://www.cloud- council.org/deliverables/CSCC-Practical-Guideto-Cloud-Computing.pdf http://www.thoughtsoncloud.com/2015/05/the-cloud-as-a-disruptive-forcejohn- hagel-of-the-deloitte-center-for-the-edge/ 1.2. Demonstrate knowledge of Cloud architecture characteristics. 1.2.1. Cloud computing is a model for enabling ubiquitous, convenient, ondemand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model is composed of five essential characteristics, three service models, and four deployment models. 1.2.2. Cloud architectures typically leverage Internet-accessible on-demand services. Applications built on cloud architectures are such that the underlying computing infrastructure is used only when it is needed (for example to process a user request), draw the necessary resources ondemand (like compute servers or storage), perform a specific job, then relinquish the resources and often dispose themselves after the job is done. While in operation, the application scales up or down elastically based on resource needs. 1.2.3. Characteristics: 1.2.3.1. On demand self service 1.2.3.2. Omni-channel access 1.2.3.3. Resource pooling 1.2.3.4. Rapid elasticity 1.2.3.5.

For example, E-learning, cloud computing, social networking, virtual laboratories, virtual realities, virtual worlds, massive open online courses (MOOCs), and bring your own device (BYOD) are all new concepts of immersive and global education that have emerged in educational literature. One of the greatest challenges presented to e-learning solutions is the reproduction of the benefits of an educational institution’s physical laboratory. For a university without a computing lab, to obtain hands-on IT training with software, operating systems, networks, servers, storage, and cloud computing similar to that which could be received on a university campus computing lab, it is necessary to use a combination of technological tools. Such teaching tools must promote the transmission of knowledge, encourage interaction and collaboration, and ensure students obtain valuable hands-on experience.

  • IBM Z/OS Mainframe to Google Cloud Platform Reference Architecture Guide
    WHITE PAPER APRIL/2021 IBM z/OS Mainframe to Google Cloud Platform Reference Architecture Guide Abstract In businesses today, across all market segments, cloud computing has become the focus of current and future technology needs for the enterprise. The cloud offers compelling economics, the latest technologies and platforms, and the agility to adapt your information systems quickly and efficiently. However, many large organizations are burdened by much older, previous generation platforms, typically in the form of an IBM mainframe computing environment. Although old and very expensive to maintain, the IBM mainframe platform continues to run the most important information systems of an organization. The purpose of this reference architecture is to assist business and IT professionals as they prepare plans and project teams to start the process of moving IBM mainframe-based application portfolios to the Google Cloud. We will also share various techniques and methodologies that may be used in forming a complete and effective Legacy Modernization plan. In this document, we will explore: • Why modernize an IBM mainframe • The challenges associated with IBM mainframe modernization • An overview of the IBM mainframe • The IBM mainframe to Google Cloud Reference Architecture • An overview of Google Cloud services • A look at the Astadia Success Methodology This document is part of the Astadia Mainframe to Cloud Modernization Series that leverages Astadia’s 25+ years of mainframe platform modernization expertise. © 2021 Astadia.
