Journey into Architectural Design Patterns

Monday, 9:00 AM EST

In this day-long work workshop, we will walk through a catalog of all the common architectural design patterns. For each design pattern, we will run docker-compose files that demonstrate the strengths and weaknesses of those design patterns. So you have a first-hand, full-on, and highly engaged full-day workshop to give you the knowledge you need to make critical architectural choices.

We will cover:

• Anti-corruption-layer
• Claim Check
• CQRS
• Gatekeeper
• Strangler Fig
• Bulkhead
• More …

Java Design Patterns Deep Dive

Tuesday, 8:30 AM EST

Since 1994, the original Gang of Four Design Patterns book, “Design Patterns: Elements of Reusable Object-Oriented Software” has helped developers recognize common patterns in development. The book was originally written in C++, but there have been books that translate the original design patterns into their preferred language. One feature of “The Gang of Four Design Patterns” that has particularly stuck with me has been testability for the most part. With the exception of singleton, all patterns are unit testable. Design Patterns are also our common developer language. When a developer says “Let's use the Decorator Pattern” we know what is meant.

What's new though is functional programming, so we will also discuss how these patterns change in our new modern functional programming world. For example, functional currying in place of the builder pattern, using an enum for a singleton and reconstructing the state pattern using sealed interfaces. We will cover so much more, and I think you will be really excited about this topic and putting it into practice on your own codebase.

Kubernetes Security Concepts Part 1

Wednesday, 1:30 PM EST

There are multiple elements to Kubernetes where each component seems like a character in a book, pods, services, deployments, secrets, jobs, config maps, and more. In this presentation, we just focus on the security aspect of Kubernetes and the components involved. Particularly centered around RBAC and ServiceAccounts. What they are, what they do. We discuss etcd and secrets. We will also discuss other options for security in Kubernetes.

• Service Accounts
• Secrets
• Kubernetes API
• Authentication
• Authorization
• RBAC
• Roles and Cluster Roles

Hashicorp Vault

Wednesday, 5:00 PM EST

Hashicorp Vault stores encrypted secrets securely. You can store anything that you want into Vault including API keys, passwords, and certificates. Vault can also store dynamic secrets where it can negotiate with a cloud service on your behalf without direct interaction with your API keys. Hashicorp Vault is well thought out “bank” of information that handles storage, encryption, leasing, sealing.

In this presentation, we will discuss setup, securing content, creating automatic secrets for AWS, sealing, how to deploy into Kubernetes, and how to integrate with code.

Machine Learning Data Pipelines

Thursday, 9:00 AM EST

This workshop builds an entire event driven data pipeline with Machine Learning and Kafka. From Kafka where we use producers or Kafka Connect to generate information, we then will Kafka Streams to apply a machine learning model to make business decisions.

This intensive lab will start by integrating sources into our backplane, then train our models, and operationalize our model using Kafka Streams. We will then create result topics when we can read in as a report and display visualizations of our data. The result will also be scalable and fault tolerant.
