The document discusses event sourcing and its place in a data storage maturity model. Event sourcing involves storing all changes to an application's state as a sequence of events. When commands are executed, events are generated and stored in a database. Projections rebuild the current state by replaying the sequence of events. Event sourcing is considered the most mature approach in the model, above CQRS and structured storage.

Most React-Redux applications store the work in progress as is in a database. It is fine to treat objects like this in a small application. But this is not optimal when applications are complex. Prefer the CQRS design pattern for more complex applications. Combining this with Event-Sourcing is an even more powerful solution. Event-Sourcing ensures that every action is stored as a separate domain event. These domain events are the CQRS write model. These events also project into a secondary database. This projection builds the CQRS read model for the application.

Migrating Monoliths to Microservices -- M3

Asir Selvasingh

Have a legacy software portfolio? Stepping into unfamiliar code, especially legacy code, can be very scary. Code uses local file system or unusual directory layout or homegrown shim for interacting with databases, cache or user directories, secrets lying bare etc. You can confront monoliths and transform them. So, where do you start when considering an app migration? What apps need to continue running for the next six years and at a lower cost? Let's look at what and why for monolith & n-tier ==> microservice architecture transformation. What are the popular microservice frameworks for Java customers? How to decompose monolith to microservices? Why Spring cloud and what are its key components? As you walk away, you will be ready to dive deeper and go hands-on with Spring Cloud microservices.

Building Event-Driven (Micro)Services with Apache Kafka

Guido Schmutz

Should we use traditional REST APIs to bind services together? Or is it better to use a more loosely-coupled protocol? This talk will dive into how we piece services together in event driven systems, how we use a distributed log (event hub) to create a central, persistent history of events and what benefits we achieve from doing so. Apache Kafka is a perfect match for building an asynchronous, loosely-coupled event-driven backbone. Events trigger processing logic, which can be implemented in a traditional as well as in a stream processing fashion. The talk will show the difference between a request-driven and event-driven communication and show when to use which.

Breaking Down the Monolith - Peter Marton, RisingStack

NodejsFoundation

The story of how we broke our Node.js monolith into 15+ services in just a couple of weeks. The talk will focus on what we have learnt during the journey and what technologies we use. This is the tale of how we did this rather than what microservices are in general. Agenda: 1. monolith and microservices in nutshell 2. advantages of microservices from our view - well focused service teams, happy customers - fault tolerance - distributed responsibility - improving quality 3. disadvantages of microservices-based our experience -growing complexity -errors in transactions -response time issue 4. how we did it -service team principles -co-operation between teams -company architecture changes -breaking down via proxy -request signing -circuit breaker -event sourcing

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
