August 2020 Summaries

Scott McNealy, a Silicon Valley legend, shares his experience on managing a company during crises, crediting mostly trial and error, but also having great mentors such as his father, Roger Penske, Ken Oshman, Jack Welch, Crawford Beveridge, and Bill MacGowan. He emphasizes the importance of managerial courage, treating people right, and creating a positive culture. McNealy reflects on the legacy of making tough choices, highlighting Sun Microsystems' success in changing the industry, spawning many CEOs, and deploying widely used technology without scandals or cheating.

The new Redis Data Source for Grafana plug-in allows DevOps practitioners and database administrators to easily create dashboards to monitor their Redis databases and application data using a familiar tool. This integration enables visualization of RedisTimeSeries data, core Redis data types like Strings, Hashes, Sets, and more. The new Data Source plug-in can connect to any Redis database, including open source Redis, Redis Enterprise, and Redis Enterprise Cloud, and works with Grafana 7.0 and later. It supports three different command types: Redis commands, RedisTimeSeries commands, and universal inputs.

We're excited to announce a new technology collaboration with AMD, which is using Redis Enterprise to benchmark Redis database on publicly launched and available AMD EPYCTM 7002 series processor powered systems, and instances in the cloud. The first series of cloud instances tested in this collaboration are the AWS EC2 C5a instances, powered by 2nd generation AMD EPYCTM processors that run at frequencies up to 3.3 GHz, offering up to 192GB of memory. This collaboration aims to demonstrate cost and performance advantages for customers while highlighting how Redis can contribute to benchmarking next-generation cloud infrastructure. The results show exceptional throughput performance and linear scalability among the different instances, making it clear that Redis running on AWS C5a instances can help boost application performance and scale with application growth.

This summary provides an overview of creating a notification service using Redis Pub/Sub with WebSocket. The demo uses Vue.js as the frontend and Node.js as the backend to create a simple WebSocket server that listens for messages on a specific channel in Redis. When a message is received, it broadcasts the message to all connected clients through the WebSocket server. The frontend application receives these notifications and displays them to the user. The example also demonstrates how to use Bootstrap to improve the design of the alert component that appears when new notifications are received.

The Redis education team has released a new course on Redis security. RU330: Redis Security covers general security principles and provides an in-depth look at Redis' basic security controls, encryption, public key cryptography, and TLS implementation. The course is led by Jamie Scott, a Redis Product Manager focused on security, and another instructor with experience in software engineering, technical authoring, and curriculum development. It takes a holistic approach to security education and aims to help users make the best decisions when deploying Redis in production. The course is instructor-paced, lasting three weeks with one more week for the final exam.

Rediscover Magazine` is a publication created by Redis to highlight the concept of "rediscovery" in various fields, including technology, products, and ideas. The magazine aims to showcase the full potential of Redis as a developer-friendly tool for building applications, going beyond its traditional role as a caching solution. It features stories on Redis itself, as well as other topics such as innovation, entrepreneurship, and industry trends, offering insights from experts in the field. The magazine is available both digitally and in print, leveraging the strengths of both formats to provide engaging storytelling and visual experiences. By rediscovering and sharing these stories, Redis aims to inspire developers, architects, and DevOps professionals to explore new possibilities and push the boundaries of what is possible with technology.

The Redis for Python Developers course, created by a 10+ year Python veteran, is now live at Redis University, offering free access to five weeks of instructor-led learning, community chat server, source code, and certificate of completion. The course aims to provide definitive patterns for writing efficient and well-organized Python code using Redis' powerful features, including integrating Redis with Flask applications, modeling data in Hashes, Sets, and Sorted sets, building geospatial indexes, and using Redis Streams. The example project uses data classes to declare Redis data models, breaking validation and persistence into separate pieces, utilizing marshmallow for serialization and deserialization. The course covers the DAO pattern for persisting models to Redis, making it suitable for both beginners and experienced Python developers.
