  1. 1. Presented by 120630107090 Bhandari Anjali Dilipbhai MBICT,VVnagar CLUSTER COMPUTING
  2. 2.  Introduction  History  Cluster architecture  How Clusters Computer works ?  Types of cluster  Components of clusters  Advantages  Disadvantages  Issuse to be considered  Application  Difference Between Cluster, Grid and cloud Computing  Conclusion OVERVIEW
  3. 3.  Cluster computing is a group of loosely coupled computers that work together closely so that in many respects it can be viewed as though it were a single computer.  Clusters are commonly connected through fast local area networks. CLUSTER COMPUTING
  4. 4.  Clusters are usually deployed to improve speed and/or reliability over that provided by a single computer, while typically being much more cost effective than single computer the of comparable speed or reliability .  In cluster computing each node within a cluster is an independent system, with its own operating system, private memory, and, in some cases, its own file system. CONTINUE...
  5. 5.  Because the processors on one node cannot directly access the memory on the other nodes, programs or software run on clusters usually employ a procedure called "message passing" to get data and execution code from one node to another.  Cluster computing can also be used as a relatively low- cost form of parallel processing for scientific and other applications that lend themselves to parallel operations. CONTINUE...
  6. 6.  Greg Pfister is a computer scientist and worked a lot for cluster computing, according to him clusters were not invented by any specific vendor but by customers.  The first commodity clustering product was ARC net(Attached Resource Computer Network), developed by Datapoint in 1977.  The next product was VAXcluster,released by DEC in 1980’s.  Microsoft, sun microsystems, and other leading hardware and software companies offer clustering packages. HISTORY
  7. 7.  A cluster is a type of parallel /distributed processing system, which consists of a collection of interconnected stand-alone computers cooperatively working together a single, integrated computing resource.  A node: • A single or multiprocessor system with memory, I/O facilities, &OS • Generally 2 or more computers (nodes) connected together • In a single cabinet, or physically separated & connected via a LAN • Appear as a single system to users and applications • Provide a cost-effective way to gain features and benefits CLUSTERS ARCHITECTURE

  9. 9. HOW CLUSTER COMPUTERS WORKS Fig :- Cluster Computer at short Glance
  10. 10.  In the above arrangement of clusters the machines are arranged through the common high speed bus in a manner that they can communicate with each other.  A simple High speed LAN can be used to connect these machines through which these machines can be accessed via web or these machines can access the web.  LAN arrangement contains numbers of busses for the flow of traffic in circuit,CPU’s to process the data, memory to storage devices to store the unprocessed (received) data and processed (transmitted) data, and shared memory will have data from number of CPU’s. WORKING
  11. 11.  High performance clusters  High availability cluster or Failover Clusters  Load balancing cluster TYPES OF CLUSTER
  12. 12.  Start from 1994  Donald becker of nasa assembled this cluster.  Also called beowulf cluster. • Dependable parallel computers • Application like data mining , simulations , parallel processing , weather modeling etc. HIGH PERFORMANCE CLUSTER
  13. 13. Fig :- High performance Cluster
  14. 14.  Avoid single point of failure.  Designed to provide uninterrupted availability of data or services to the end  This requires atleast two nodes a primary and a backup.  Always with redundancy.  Almost all load balancing cluster are with HA capability.  Used to implement database, mail, file print, web application servers. HIGH AVAILABILITY CLUSTERS OR FAILOVER CLUSTERS
  15. 15. Fig :- High Availability Cluster
  16. 16.  Pc cluster deliver load balancing performance.  It distributes incoming requests for resources or content among multiple nodes running the same programs or having the same content  Each node in cluster is able to handle requests for the same content or application.  Both the high availability and load balancing cluster technologies can be combined to increase the reliability, availability , and scalability of application and data resources that are widely deployed for web , mail or FTP services. LOAD BALANCING CLUSTER
  17. 17. Fig :- Load Balancing Cluster
  18. 18.  The basic building blocks of clusters are broken down into multiple categories:  The cluster nodes,  Cluster operating system,  Network switching hardware and  The node/switch interconnect COMPONENTS OF CLUSTER
  19. 19.  Availability • In case if server is having a problem another server from the cluster takes over the server having issue. This ensure the high availability of web applications.  Scalable • Server clustering is completely a scalable solution. Resources can be addeded to the cluster accordingly.  Load Handling and maintenance • If a dedicated server from the cluster requires maintenance,it can be stopped while other servers handles.  Easy to manage • More easy cluster management software are emerging to manage the clusters and in present also some are available. ADVANTAGES
  20. 20.  More Space is required • Server clustering usually requires more servers and hardware to manage and monitor thus increases the infrastructure. Some web hosting providers may afford it.  Very expensive • It is not a cost-effective solution, as it needs a good server design which can be a bit expensive. DISADVANTAGES
  21. 21.  Cluster networking  Cluster software  Programming  Timing  Network selection  Speed selection ISSUSE TO BE CONSIDERED
  22. 22.  Web serving/searching (google search engine)  Email , echat , ebook, ebank  E-commerce application(amazon.com, ebay.com)  Weather forecasting  Computational fluid dynamics  Petroleum Reservoir Simulation  Earthquake Simulation.  Image Rendering. APPLICATIONS
  23. 23.  Grid Computing: - It is collection of computer resources from multiple locations to reach a common goal.  Cluster Computing: - It is a form of computing in which a group of computers are linked together so that they can act like a single entity.  Cloud Computing :- It is a type of com putting that relies on sharing computing resources rather than having local servers or personal devices to handle applications.
