💻 More software engineering videos 🤍 Load balancing is process of balancing incoming requests to multiple machines, processes or services. In this video we will explain two types of load balancers, layer 4 and layer 7. Chapters 0:00 Intro 6:00 L4 Load balancer 9:10 L4 Load Balancer Pros and Cons 16:18 Example L4 Load Balancer with HAPROXY 22:30 L7 Load Balancer 27:00 L7 Pros and Cons 31:00 Example L7 Load Balancer with HAPROXY 37:00 Summary Layer 4 (4/3) Take content forwards it based on basic rules, it knows ip and port and perhaps latency of the target service. Layer 4 - haproxy, NLB Pros - great for simple packet-level load balancing - Fast and efficient doesn’t look at the data - More secure as it cant really look at your packets. So if it was compromised no one can look - Uses NAT - One connection between client and server NATed Cons - Cant do smart load balancing based on the content, such as switch request based on requested media type - Cant do microservices with this type - Has to be sticky as it is a stateful protocol (all segments) Layer 7 (Nginx , haproxy) This type of proxy actually looks at the content and have more context, it knows you are visiting the /users resources so it may forward it to a different server. Essential and Great for microservices , it knows the content is video:image etc.. it can also cache.. we cant really do caching on layer 4 because we have no clue whats in the packets. But expensive because it has to decrypt and look and compute Layer 4 - haproxy, nlb - great for simple packet-level load balancing - fast and efficient doesn’t look at the data - More secure as it cant really look at your packets. So id it was compromised no one can look - Uses NAT - One connection between client and server NATed Layer 7 - examples nginx - Smart routing based on the url (microservices) flexible - Provide caching - Expensive need to decrypt - Secuirty, you have to share your certificate with the load balancers. Id compromised attacker has access to all your data. - Proxy creates multiple connection (client to proxy/proxy to server) Image thumbnails 🤍 Support me on PayPal 🤍 Become A Patron 🤍 Stay Awesome!

In this video, I delve into the topic of HAProxy health checks, focusing on different types (Active, Passive, Agent) of health checks and their role in layer 4 load balancing. I provide a detailed explanation of how health checks work and why they are crucial for ensuring the availability and reliability of backend servers. Furthermore, I demonstrate the implementation of health checks in HAProxy and conduct tests to showcase the impact of using or not using health checks in layer 4 load balancing scenarios. By the end of the video, viewers will have a solid understanding of health checks in HAProxy and their significance in maintaining a robust and resilient infrastructure.

Since its first release in 2014, HashiCorp Consul has evolved from an open-source tool that provides service discovery, health checking, load balancing, globally distributed key value store to pioneering microservice networking with service mesh capabilities. Since then, the Consul team has released first class integrations with Kubernetes, Envoy, AWS Cloudmap, and more. However, before considering full-fledged service mesh, many companies looking to adopting microservices architectures are still struggling to come up with an optimized load balancing approach with their existing networking architecture. - If you liked this video and want to see more from HashiCorp, subscribe to our channel: 🤍 To learn more, visit our hands-on interactive lab environment, HashiCorp Learn: 🤍 HashiCorp is the leader in multi-cloud infrastructure automation software.

In 2018, we migrated several video-on-demand/replay platforms from on-premise to the AWS cloud. HAProxy was the key to this migration, allowing us to move safely and without any downtime. We’ll take a deep dive through the configuration used to secure our migration, highlighting aspects such as our use of the “observe layer7” keyword. I’ll also cover how we use GOReplay to replicate traffic and our use of the HAProxy Ingress Controller in front of our Kubernetes clusters.

At GitHub, we’re supporting a community where more than 36-million people learn, share, and work together to build software. This requires building fault tolerant systems and reliable software that’s able to serve tens of thousands of requests every second. Our load balancing solution, which we call the GitHub Load Balancer (GLB), uses HAProxy to maintain high availability of our most critical services. In this talk, I will share what it took to build GLB and how we came to its current design and implementation.
