    šŸŽ‰ Ververica Announces Public Availability of Bring Your Own Cloud (BYOC) Deployment Option on AWS Marketplace Enabling Ultra-High Performance and Scalable Real-Time Data Streaming Solutions on Organizations' Existing Cloud Infrastructure Ververica, creators of Apache FlinkĀ® and a leader in real-time data streaming, today announced that its Bring Your Own Cloud (BYOC) deployment option for the Unified Streaming Data Platform is now publicly available on the AWS Marketplace. This milestone provides organizations with the ultimate solution to balance flexibility, efficiency, and security in their cloud deployments. Building on Ververica’s commitment to innovation, BYOC offers a hybrid approach to cloud-native data processing. Unlike traditional fully-managed services or self-managed software deployments, BYOC allows organizations to retain full control over their data and cloud footprint while leveraging Ververica’s Unified Streaming Data Platform; by deploying it on a zero-trust cloud environment. ā€œOrganizations face increasing pressure to adapt their cloud strategies to meet operational, cost, and compliance requirements,ā€ said Alex Walden, CEO of Ververica. ā€œBYOC offers the best of both worlds: complete data sovereignty for customers and the operational simplicity of a managed service. With its Zero Trust principles and seamless integration into existing infrastructures, BYOC empowers organizations to take full control of their cloud environments.ā€ Key Benefits of BYOC Include: • Flexibility: BYOC integrates seamlessly with a customer’s existing cloud footprint and invoicing, creating a complete plug-and-play solution for enterprises’ data processing needs. • Efficiency: By leveraging customers’ existing cloud resources, BYOC maximizes cost-effectiveness. Organizations can leverage their negotiated pricing agreements and discounts; all while avoiding unnecessary networking costs. • Security: BYOC’s design is built on Zero Trust principles, ensuring the customer maintains data governance within the hosted environment. • BYOC further embodies Ververica’s ā€œAvailable Anywhereā€ value, which emphasizes enabling customers to deploy and scale streaming data applications in whichever environment is most advantageous to them. By extending the Unified Streaming Data Platform’s capabilities, BYOC equips organizations with the tools to simplify operations, optimize costs, and safeguard sensitive data. For more information about Ververica’s BYOC deployment option, visit the AWS Marketplace listing or learn more through Ververica’s website.

    Hello folk, I wanted to discuss our current system setup and see if Apache Flink would be a good fit to replace one of our consumer groups. Right now, we have two Kafka consumer groups: the raw-consumer group, which is scalable and handles the input from vehicles, and the parsed-consumer group, which handles the post-processing tasks like decoding and filtering. The issue we’re facing is that while the raw-consumer group can scale effectively with the number of vehicles, the parsed-consumer group starts to slow down when we increase the load, especially as the tasks it performs are quite CPU-intensive. Currently, we’re running the system with 20 vehicles, and here’s the resource breakdown: We have 20 pods, each allocated 150 millicores (0.15 vCPU) and 400 MB of memory. That totals 3 vCPUs and 8 GB of memory. However, when scaling to 10,000 vehicles, we’re expecting a significant increase in resource usage. Specifically, we’ll need 250 pods, which translates to 37.5 vCPUs and 100 GB of memory. Given this, we’re wondering if replacing the parsed-consumer group with Apache Flink would be a good solution. Flink is known for handling heavy processing tasks like decoding and filtering efficiently, and we believe it could scale better to meet the needs of our growing vehicle fleet. Would Flink be able to handle this load more effectively than our current parsed-consumer group? And if we were to make this transition, would it provide the scalability we need without running into performance issues or excessive resource consumption? I just wnat some good suggestions? As no other company having similar use case i couldn't find any article or so.
