Founder, DefMacro Software
Raju is a software craftsman with almost 20 years of hands-on experience scoping, architecting, designing, implementing full stack applications.
He provides a 360 view of the development cycle, is proficient in a variety of programming languages and paradigms, experienced with software development methodologies, as well an expert in infrastructure and tooling.
He has long been in the pursuit of hermeticism across the development stack by championing immutability during development (with languages like Clojure), deployment (leveraging tools like Docker and Kubernetes), and provisioning and configuration via code (toolkits like Ansible, Terraform, Packer, everything-as-code).
Raju is a published author, internationally known public speaker and trainer.

In his spare time, you will find Raju reading, playing with technology, or spending time with his wonderful (and significantly better) other half.

Measuring your architecture
Wednesday, 9:00 AM EST
It's not just architecture—it's evolutionary architecture. But to evolve your architecture, you need to measure it. And how does that work exactly? How does one measure something as abstract as architecture?
In this session we'll discuss various strategies for measuring your architecture. We'll see how you know if your software architecture is working for you, and how to know which metrics to keep an eye on. We'll also see the benefits of measuring your architecture.
We'll cover a range of topics in this session, including
Different kinds of metrics to measure your architecture
The benefits of measurements
Improving visibility into architecture metrics
Container Usage Patterns
Wednesday, 11:00 AM EST
Embraced containers yet? If so, that only presents the beginning of the journey. Designing your images to be lean, and your containers configurable requires us to leverage Dockerfiles to their maximum potential. At scale, everything matters—build times, testing, multi-stage builds, conventions around tagging and logging. There is a whole ecosystem of tools around how we can best build our images and containers.
In this session we will learn many a trick on how we can leverage Docker's own tooling as well as third-party tools to ensure that our first steps in the container world are the right ones.
DDD and Microservices
Wednesday, 1:30 PM EST
We live in a world of microservices. Yet, what is a microservice? What defines the boundaries of a microservice? How do we define the relationships between microservices? Thankfully domain-driven design gives us the concepts and practices to better design and decompose our services.
In this session we will consider many of the concepts of DDD — How bounded contexts use Ubiquitous language to model the domain, how context maps can be used to establish the interconnections between services as well aggregates and domains events, all of which will service us well as we go about creating our microservices.
We will also discuss the “tactical” patterns of DDD — We will see how we can “embed” the ubiquitous language in code, and the architectural influences of DDD.
This workshop will have you thinking about how to think in DDD using DDD concepts and ideas. Using polls, and mini-exercises we attempt to better cement the ideas of DDD so we can start applying them at work.

Terraform-ing your cloud
Wednesday, 5:00 PM EST
A large part of embracing DevOps involves embracing automation. Over the last decade we have seen the emergence of “as Code” — Build-as-Code, Configuration-as-Code and Infrastructure-as-Code. The benefits to utilizing such tools are huge! We can codify the state of the world around our applications, giving us the ability to treat everything that our code needs like we treat the code itself. Version control, release management, tagging, even rolling backs are now possible. Terraform, an open-source tool from HashiCorp allows us to build, control and modify our infrastructure. Terraform exposes a Domain-specific language (DSL) that we can use to express what our infrastructure should look like. Terraform can work with all the major cloud providers, including Amazon AWS, Google GCP and Microsoft Azure. If you are curious about what this tool has to offer, this session is for you. Come on in, and let's learn how to terraform your cloud.
This session will focus on Terraform. We will look in to how this tool works, explore its capabilities, and see how it can play a pivotal role in our Infrastructure-as-Code (IaC) strategy. With lots of code and demos, this session will certainly give you enough fodder for thought, and provide a baseline so you can decide if Terraform is right for you.
Container Security Fundamentals Part I
Thursday, 9:00 AM EST
Containers are everywhere. Of course, a large part of the appeal of containers is the ease with which you can get started. However, productionizing containers is a wholly different beast. From orchestration to scheduling, containers offer significantly different challenges than VMs.
In particular, in terms of security. Securing and hardening VMs is very different than that for containers.
In this twopart session, we will see what securing containers involves.
We'll be covering a wide range of topics, including
Understanding Cgroups and namespaces
What it takes to create your own container technology as a basis of understanding how containers really work
Securing the build and runtime
Secrets management
Shifting left with security in mind

Head First Git: A Learner's Guide to Understanding Git from the Inside Out
by Raju Gandhi
-
Many people who use Git rely on "recipes"--copying and pasting commands they find on the internet without really understanding how Git actually works. But what do you do if you find yourself in a tight spot? You can't simply wing it. With this unique hands-on guide, you'll learn the ways of Git and have fun while doing it. Raju Gandhi peels back the layers to reveal the simple yet powerful engine that powers Git, so you'll understand not just the how but the why. You'll master branches, merges, commit messages, search, utilities, and more; learn best practices for collaborative work; and unlock the full potential of Git.
If you've read a Head First book, you know what to expect--a visually rich format designed for the way your brain works. If you haven't, you're in for a treat. With this book, you'll learn Git through a multisensory experience that engages your mind rather than a text-heavy approach that puts you to sleep.
