uptake in many different computing sectors. The book also contains many insights about computer architecture in general, as well as explaining the particular design choices we made in creating RISC-V. I the point, and complete. The book’s commentaries provide a gratuitous history, motivation, and architecture critique. —C. Gordon Bell, Microsoft and designer of the Digital PDP-11 and VAX-11 instruction handy little book effortlessly summarizes all the essential elements of the RISC-V Instruction Set Architecture, a perfect reference guide for students and practitioners alike. —Professor Randy Katz, University

## +24 ## High-Performance Cross-Platform Architecture: C++20 Innovations ## NOAH STEIN ## About Me • 35-year career in video games and embedded software • Started using C++ in 1995 • First cross-platform cross-platform project in 1994 ## Cross-Platform Architecture Goals • Take advantage of all platforms • Focus on the compiler • Minimize boilerplate and unnecessary code • Minimize redundant code • Minimize occurs ## • Strong OCP • No previous code is modified in any way • Nothing is recompiled ## Architecture Guidelines • Very close to Bertrand Meyer’s original vision • Not OOP, data and functions separate

access to EC2 (for developers) ## Agenda – introduction – EC2 in native environment – 3-tier architecture intro – alternative methods of resource connection: – Bastion host - SSM – EC2 Instance disable default users - root – ubuntu – ec2-user – use security groups or equivalent 3-tier architecture  ![Image -tier architecture - props and cons – full control over resource access – possibilities of disconnection resources from the internet – in general, more secure ## unfortunately – architecture getting

Agile. This frame of reference includes the notions of project, systems, application, investment, architecture, skill set, and accountability. We have, to be honest, made a jumble of these concepts. IT as asset, which I will call – despite some disconcerting connotations of the term – the Enterprise Architecture. The asset view of IT will substitute for the outdated project view in my vision for what IT leadership modernizations. In the absence of the strangler pattern, we would develop a new system on the modernized architecture and then move the users over to it. The problem is that the users cannot begin using the new system
