Lets Architect the Performance Engineering

  In today's digital age, SaaS applications are synonymous with agility and adaptability. Their very essence lies in their capacity to scale and meet burgeoning user demands seamlessly. In this detailed guide, we'll explore the nuances of scaling, its impact on performance, and real-life instances of scaling in action. The Genesis: Understanding Scaling Scaling, in the world of SaaS, refers to an application's ability to accommodate an increase in user load, ensuring that as demand surges, the system remains both responsive and performant. It’s the invisible cog ensuring your application runs smoothly, regardless of the number of concurrent users. The Two Pillars of Scaling : Horizontal Scaling (Scale-Out) : Definition : Envision adding more tables (machines) to a vast dining hall (system). Each table can serve a set number of guests (workloads). Advantage : It's like having multiple mini-stores instead of one mega-store. If one store closes, others continue to operate....

SaaS (Software as a Service) has revolutionized business operations by providing a wide range of cloud-based tools and apps that boost productivity. However, with this move to the cloud, it is essential to provide continuous performance and high availability. The unsung heroes of your cloud-based services, load balancers, are here to ensure that your services stay responsive and dependable. What is Load Balancing? At its essence, load balancing involves effectively spreading incoming network traffic among a number of backend servers. This procedure guarantees high availability and redundancy in case of failures by guaranteeing that no single server is subjected to an excessive amount of demand. Types of Load Balancers: Layer 4 Load Balancer (Transport Layer) : Operates at the transport layer, making routing decisions based on IP address, ports, or both. Example: TCP Load Balancer. Layer 7 Load Balancer (Application Layer) : Operates at the application layer, deciding traffic distributi...
