|I have attempted to learn AADL and how to use OSATE several times over the years. I would read a good article on it and think to myself I can figure it out this time.
A day or two into the adventure I would get frustrated with the toolset and getting it configured correctly, and the scattered and confusing details of AADL would put the nail in the coffin of my past attempts.
I was hoping this book would not have me repeating history. I am glad to report it didn't. Finally a resource that puts AADL information into a learnable format.
The book starts off with a nice introduction to model-based software systems engineering and does a good job of putting a AADL into context by comparing it to SysML, VHDL, and UML.
The book is broken down into two main parts and then has some appendixes. I have listed the parts along with the chapters they contain below.
Part I. Model-Based Engineering and the AADL
Chapter 1. Model-Based Software Systems Engineering
Chapter 2. Working with the SAE AADL
Chapter 3. Modeling and Analysis with the AADL: The Basics
Chapter 4. Applying AADL Capabilities
Part II. Elements of the AADL
Chapter 5. Defining AADL Components
Chapter 6. Software Components
Chapter 7. Execution Platform Components
Chapter 8. Composite and Generic Components
Chapter 9. Static and Dynamic Architecture
Chapter 10. Component Interactions
Chapter 11. System Flows and Software Deployment
Chapter 12. Organizing Models
Chapter 13. Annotating Models
Chapter 14. Extending the Language
Chapter 15. Creating and Validating Models
Appendix A. Syntax and Property Summary
Appendix B. Additional Resources
Appendix C. References
The book is broken down into a nice logical flow that starts with simple models and as it continues the authors grow the models complexity.
In Part I the authors use a sample system that builds a powerboat autopilot architecture. By the end of Part I you have a detailed understanding of the AADL capabilities.
In Part II the authors take you on a detailed tour of all the critical elements in AADL. After a describing the different categories the AADL components fall into the authors spend several chapters going into great detail on how to use them.
The book includes a big appendix that summarizes AADL syntax and grammar rules, lists the component type and implementation elements, lists the basic property types and type constructors, lists the AADL reserved words, and the AADL properties.
The authors have a really good writing style which makes the content not only easier read but also easy to understand.
There were only two things that would have made life easier while learning AADL using the book. The authors should make the samples used throughout the book available online for download. There is a lot of typing to do to get the examples working.
The second thing is better coverage of configuring the Open Source AADL Tool Environment (OSATE) used to create the models in the book. The best thing to do is to download TOPCASED (do yourself a favor and download and run the RCP downloads), then install OSATE2, Xtext, and ADELE using the Eclipse Install New Software feature on the Help menu, and uninstall OSATE1 which comes with TOPCASED using the Installation Details button on the About Eclipse dialog.
These two dings don't take anything away from the book, and they probably made me use the tool more and therefore learn more about the tool than had they spoon fed me.
This book is literally the only book on the market available for learning AADL. Luckily it's a great resource and by reading it cover to cover, working through the exercises, and building the models you will definitely learn the AADL language.
I highly recommend the book to anyone who wants to learn AADL!!!

Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership abi...

Without a clear strategy for cost control and an architecture designed with cloud services in mind, costs and operational performance can quickly get out of control. To avoid multiple architectural redesigns requires extensive thought and planning. Boundary (now part of BMC) launched a new public-facing multi-tenant high resolution monitoring service on Amazon AWS two years ago, facing challenges and learning best practices in the early days of the new service.

All organizations that did not originate this moment have a pre-existing culture as well as legacy technology and processes that can be more or less amenable to DevOps implementation. That organizational culture is influenced by the personalities and management styles of Executive Management, the wider culture in which the organization is situated, and the personalities of key team members at all levels of the organization. This culture and entrenched interests usually throw a wrench in the work...

DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm.

As software becomes more and more complex, we, as software developers, have been splitting up our code into smaller and smaller components. This is also true for the environment in which we run our code: going from bare metal, to VMs to the modern-day Cloud Native world of containers, schedulers and micro services. While we have figured out how to run containerized applications in the cloud using schedulers, we've yet to come up with a good solution to bridge the gap between getting your contain...

DevOps has often been described in terms of CAMS: Culture, Automation, Measuring, Sharing. While we’ve seen a lot of focus on the “A” and even on the “M”, there are very few examples of why the “C" is equally important in the DevOps equation. In her session at @DevOps Summit, Lori MacVittie, of F5 Networks, explored HTTP/1 and HTTP/2 along with Microservices to illustrate why a collaborative culture between Dev, Ops, and the Network is critical to ensuring success.

An overall theme of Cloud computing and the specific practices within it is fundamentally one of automation. The core value of technology is to continually automate low level procedures to free up people to work on more value add activities, ultimately leading to the utopian goal of full Autonomic Computing. For example a great way to define your plan for DevOps tool chain adoption is through this lens. In this TechTarget article they outline a simple maturity model for planning this.

While DevOps most critically and famously fosters collaboration, communication, and integration through cultural change, culture is more of an output than an input. In order to actively drive cultural evolution, organizations must make substantial organizational and process changes, and adopt new technologies, to encourage a DevOps culture. Moderated by Andi Mann, panelists discussed how to balance these three pillars of DevOps, where to focus attention (and resources), where organizations might...

The rise of containers and microservices has skyrocketed the rate at which new applications are moved into production environments today. While developers have been deploying containers to speed up the development processes for some time, there still remain challenges with running microservices efficiently. Most existing IT monitoring tools don’t actually maintain visibility into the containers that make up microservices. As those container applications move into production, some IT operations t...
