Companies need a data-processing solution that increases the speed of business agility, not one that is complicated by too many technology requirements. This requires a system that delivers continuous/real-time data-processing capabilities for the new business reality.
Stream processing is a hot topic right now, especially for any organization looking to provide insights faster. But what does it mean for users of Java applications, microservices, and in-memory computing? In this webinar, we will cover the evolution of stream processing and in-memory related to big data technologies and why it is the logical next step for in-memory processing projects.

Update streaming jobs in Hazelcast Jet without data loss or interruptions.
Overview
Job Upgrade makes use of Jet state snapshots to address a variety of requirements, including modifications in business logic, bug fixes, and configuration changes.
Easy to Implement
Job upgrades can be triggered via a Java API or from a command line.
State snapshots of current jobs are taken and saved.
New classes or changes are distributed to the Jet nodes.
New versions are started, and data is read from the saved snapshot.
No Disruption to Customers
Everything listed above happens in milliseconds, with essentially no latency.
Allows A/B Testing on New Features
Multiple versions of a Jet Job can run concurrently, writing results to separated sinks.
After the testing period, pick the better version, and shut down the other.
Features
Introduce relevant filtering or transforming steps to streaming data-centric applications.
Change business rules or add new operators as the business logic driving your streaming applications evolves.
Change IP addresses for sources or sinks without disrupting streaming services.

This case study on how Airbus Defence and Space uses Hazelcast is a great example of how ease-of-use goes a long way in helping engineers build critical systems for large-scale initiatives.
Blue/green deployment refers to a software technique that can be used to reduce or even eliminate systems downtime and its associated business risk by deploying two mirrored production environments referred to as Blue and Green. This white paper will walk you through these deployments, the features, and several use cases.
This talk gives you a gentle introduction into consistency models and will help you with reasoning about trade-offs.
