LJC: Real-time Stream Processing in Spring Made Easy

Needs a location

*** This is a placeholder for the event being run on Eventbrite. Please sign up with your full name at https://www.eventbrite.co.uk/e/ljc-real-time-stream-processing-in-spring-made-easy-tickets-393901569197***

About the event

Real-time stream processing is growing exponentially in recent years, businesses need to gather insights from real-time data as soon as it’s generated. To do this, developers and software architects use various pipelines and tools to capture and process data in motion. Real-time stream processing has its own challenges such as windowing, event time and late events, streaming fault tolerance, and processing guarantees. On the other hand, Spring is all about simplicity, and the question becomes how can you develop a real-time stream processing in Spring?

In this talk, you will learn how to overcome these challenges and best practices for real-time stream processing using the Hazelcast open-source platform. The talk will include a demo to show how you can optimize your real-time streaming projects in Spring in the following areas: scalability, performance, failover, reliability, and data recovery, the code will be available on Github.

*** This is a placeholder for the event being run on Eventbrite. Please sign up with your full name at https://www.eventbrite.co.uk/e/answering-cloud-security-questions-of-all-the-stakeholders-tickets-392236157907***

About the event

Many organizations are shifting their workloads on to the Cloud-based deployments, availing multiple services offered by the Cloud Service Providers, often in Hybrid or Multi-Cloud mode. Cloud security though is still grey area, with responsibility spanning across multiple stakeholders, like CSPs, Customers, Developers, and Cloud Service Partners.

In my session, I will be covering basic questions related to Cloud Security including:

• Why it is important for all parties?
• How attackers can take benefits of improper security planning risking the overall deployment structure
• How we can identify, mitigate, and avoid these security risks?
• When should we start discussing security plans?
