Clustered systems, ek aise computing system hai jisme multiple independent servers ya nodes ek saath kaam karte hai. Ye nodes ek cluster ke roop mein jude hote hai aur ek saath coordinated tarike se kaam karte hai.
Clustered systems ke do pramukh prakar hote hai:
- High Availability (HA) Clusters: High availability clusters ka uddeshya hota hai uninterrupted service pradan karna. Isme multiple nodes hote hai jo ek dusre ke backup ke roop mein kaam karte hai. Agar kisi node mein kharabi aati hai, to dusra node uska sthan lekar kaam ko sambhalta hai, jisse service continuity bani rahti hai. Isme failover mechanisms ka istemal hota hai, jisse agar ek node fail ho jaaye to dusra node automatic tarike se uska sthan le leta hai.
- Load Balancing Clusters: Load balancing clusters ka uddeshya hota hai kaam ko evenly distribute karna. Isme multiple nodes hote hai jo tasks aur requests ko saman roop se distribute karne mein madad karte hai. Load balancing algorithms ka istemal hota hai jisse workload har node par barabar tareeke se banta hai, jisse system ki samayikata, tezi aur performance badhti hai.
Advantage of Clustered systems are:-
- High performance: Clustered systems multiple nodes par tasks ko distribute karke parallel processing ki suvidha pradan karte hai, jisse kaam ki tezi aur samay rahit prabandhan badhta hai. Isse bade scale ke computational tasks aur data-intensive applications mein behtar performance prapt hoti hai.
- Increased reliability: Clustered systems mein fault tolerance hota hai, jisse agar kisi node mein kharabi aati hai to dusre nodes kaam ko sambhal sakte hai. Isse system ki sthirta badhti hai aur single point of failure ki sambhavna kam hoti hai.
- Scalability: Clustered systems aasani se scalable hote hai. Aap additional nodes ko cluster mein jod sakte hai, jisse processing power aur storage capacity badh jati hai. Isse vyavasayik avashyaktaon ke anusar badlav kiya ja sakta hai aur cluster ko flexibly expand kar sakte hai.
- High Availability: High availability clusters mein failover mechanisms hota hai, jisse agar ek node fail ho jaaye, to dusra node uska sthan le sakta hai. Isse high availability aur uninterrupted service prapt hoti hai.
- Load Balancing: Load balancing clusters mein workload evenly distribute hota hai, jisse har node par saman beban rakha jata hai. Isse kaam ka bhandaar samay rahit tareeke se sampann hota hai aur system ki samayikata aur performance badhti hai.
- Cost-Effectiveness: Clustered systems mein resources ka sahi tarike se istemal kiya jata hai, jisse cost-effectiveness badhti hai. Aap existing hardware resources ka bhi upyog kar sakte hai, jisse cost kam hoti hai.
Overall, clustered systems high performance, reliability, scalability, high availability, load balancing, aur cost-effectiveness ke saath aate hai. Ye systems bade scale ke applications, web services, databases, e-commerce platforms, aur high-performance computing ke liye upyogi hote hai.
