Load balancing kya hota hai?

Load balancing ek technique hai jo multiple servers ya resources ke beech mein incoming network traffic ya workload ko distribute karta hai taki har server ya resource ko equal amount of work mil sake. Iska mukhya uddeshya hai system performance ko optimize karna, downtime ko minimize karna, aur overall reliability aur scalability ko badhane ka.

Load balancing ka kaam hota hai incoming requests ko various servers ya resources mein distribute karna, depending on factors like server load, availability, network conditions, aur other parameters. Load balancers ek centralized point of contact hote hain jo incoming traffic ko analyze karte hain aur appropriate server ya resource ko select karte hain jahan request ko forward kiya ja sakta hai.

• 1. Round Robin: Ismein, incoming requests ko sequentially har available server ya resource mein distribute kiya jaata hai. Yeh ek simple aur easy to implement load balancing technique hai.
• 2. Least Connection: Ismein, incoming requests ko woh server ya resource select kiya jaata hai jismein sabse kam active connections hain. Yeh technique server load ko evenly distribute karne mein madad karta hai.
• 3. IP Hash: Ismein, incoming requests ke IP address ko basis banakar ek specific server ya resource ko select kiya jaata hai. Yeh technique ensures ki ek specific user ka traffic hamesha ek hi server par pahunche, jo session consistency ko maintain karta hai.
• 4. Weighted Round Robin: Ismein, har server ya resource ko ek weight assign kiya jaata hai jo uski capacity ya performance ko reflect karta hai. Requests ko distribute karte waqt, servers ke weights ke hisab se traffic ko distribute kiya jaata hai.

Overall, load balancing ek important concept hai high traffic websites, web applications, aur distributed systems ke liye jahan multiple servers ya resources ka istemal hota hai. Load balancing systems performance ko optimize karta hai, downtime ko minimize karta hai, aur overall system reliability aur scalability ko enhance karta hai.
