Most observability platforms are too expensive to fully monitor large distributed systems at scale, leading to issues like short data retention windows and discarded data. And these distributed systems are growing larger and more complex while emitting more log data than ever before. With many traditional observability solutions struggling to keep up with increases in log volume and system complexity, is observability still worth the effort and expense?

HTTP/1 vs. HTTP/2 vs. HTTP/3 HTTP/1 Key Features 1. Text-Based: HTTP/1.1 is a text-based protocol where each request/response is independent. 2. Sequential Requests: Each resource requires a separate TCP connection, leading to inefficiencies like head-of-line blocking. 3. Limited Pipelining: While pipelining was introduced, it was rarely used due to complex issues with proxies and servers. Limitations: High latency and inefficiency due to multiple TCP connections and sequential data transfer. HTTP/2 Key Features: 1. Binary Protocol: HTTP/2 uses binary framing, which is more efficient than the text-based HTTP/1. 2. Multiplexing: Multiple requests and responses can be sent simultaneously over a single TCP connection, reducing latency. 3. Header Compression: Uses HPACK compression to reduce the size of headers, further speeding up data transfer. 4. Server Push: Allows servers to send resources proactively to the client before they are requested. Advantages: Significantly reduces latency and improves the loading time of web pages by minimizing the number of connections and efficiently handling multiple streams. HTTP/3 Key Features: 1. Uses QUIC: HTTP/3 is built on top of the QUIC protocol, which uses UDP instead of TCP, offering faster connection setup. 2. Reduced Latency: QUIC reduces latency through quicker handshake processes and better handling of packet loss. 3. Multiplexing without Head-of-Line Blocking: HTTP/3 allows multiple streams within a single connection without the risk of head-of-line blocking, which is a limitation in TCP-based HTTP/2. 4. Improved Security: QUIC inherently provides better security with built-in encryption and better resistance to certain types of attacks. Advantages: Offers faster and more reliable connections, particularly for mobile and high-latency environments, leading to improved user experience and performance. --- If you liked this post: ??

Understanding load balancing algorithms is fundamental for building resilient and scalable systems. This article on Dev.to provides a comprehensive overview of different load balancing techniques, such as Round Robin, Least Connections, and IP Hashing, each offering unique benefits depending on the use case. For instance, Round Robin is straightforward and effective for evenly distributing requests, while Least Connections is ideal for maintaining balanced loads across servers with varying capabilities. As businesses scale, selecting the right algorithm becomes crucial for optimizing resource utilization and ensuring high availability. #SystemDesign #LoadBalancing #ScalableArchitecture #DevTo #TechInsights #ITInfrastructure #CloudComputing #TechExpert #LinkedInTech #ITManagement https://lnkd.in/gqsDX6HZ

?? BREAKING CHANGE: Switching from Async Mechanism to SANS-IO Runtime in Atm0s SDN Open Source Project with PR #144 Entire Rewrite Focused on Performance and SDN Architecture with an emphasis on performance and the incorporation of a Software-Defined Networking (SDN) architecture. The fundamental idea revolves around a central controller and a set of dedicated workers. Controller: Responsible for the core logic of the network system. Workers: Focused exclusively on data processing. They can handle small tasks related to data but are primarily concerned with data-related operations. If centralized logic is required, they forward data to the controller. Features: Essential components including key-value (kv) storage, data transfer, publish-subscribe (pubsub), and routing. Services: Extendable logics that allow for custom functionalities, essentially acting as user applications running within nodes. Integration and Extension Methods: Write Service: A method for extending or integrating with other services. Controller External Interface: Allows for calling from the controller to interact with external services. New Features Introduced a network graph visualization with dynamic updates and WebSocket support. Automated deployment, installation, and network testing processes for atm0s-sdn-node. Enhanced networking capabilities including VPN connection setup and network event management. #NetworkInnovation #DecentralizedNetworking #atm0sSDN
