2. Push collected tweets to Kafka cluster
3. Utilize Apache Flink Streaming to process (parse, filter and tranform) tweets
4. Ingest processed tweets to Elasticsearch for data persistance and index
5. Develop SpringBoot RESTful API server to query tweets from Elasticsearch
6. Visualize real time tweet trends with Frontend Angular web application
7. Show Geographical Tweet Heat Map with Kibana
8. Create Docker image and deploy microservices to Kubernetes cluster
