Load Balancing in Cloud Computing

Load Balancing in Cloud Computing

In cloud computing, if users are increasing load will also be increased, the increase in the number of users will lead to poor performance in terms of resource usage, if the cloud provider is not configured with any good mechanism for load balancing and also the capacity of cloud servers would not be utilized properly. This will confiscate or seize the performance of heavy loaded node. If some good load balancing technique is implemented, it will equally divide the load (here term equally defines low load on heavy loaded node and more load on node with less load now) and thereby we can maximize resource utilization. One of the crucial issue of cloud computing is to divide the workload dynamically.

Load Balancing in Cloud Computing: A Review

Load Balancing in Cloud Computing: A Review

ABSTRACT: Cloud computing in a nutshell provides on-demand access to visualized IT resources that can be shared by others on “pay-as-use” policy. It is an awesome platform in next stage of evolution of internet that leverages various opportunities to improve the way in which we think about and implement the practices and technology needed to secure the things that matters us the most. With the recent advent of technology, it has revolutionized the information technology industry by enabling elastic on-demand provisioning of computing resources. Central to these issues lies the establishment of an effective load balancing algorithm. The load can be CPU load, memory, capacity, delay or network load. Load balancing is the process of distributing the load among various nodes of a distributed system to improve both resource utilization and job response time by avoiding a situation where some of the nodes are heavily loaded while other under -loaded or nodes are idle. Load balancing ensures that all the processor in the system or every node in the network distributes equal amount of work at any instant of time. Technique can be sender initiated, receiver initiated or symmetric type (combination of sender initiated and receiver initiated types) for balancing load and can also be categorized static or dynamically. This paper is a brief discussion on different load balancing techniques and comparison between them.

An Approach to Load Balancing In Cloud Computing

Cloud computing provides online resources and online storage to the user’s .It provides access to the resources and all the data at a lower cost to them. In Cloud computing the cloud provider outsources all the resources to their client. There are many existing issues in cloud computing. The main problem is load balancing in cloud computing. Load balancing helps to distribute all loads between all the nodes. It also ensures that every computing resource is distributed efficiently and fairly. It provides high satisfaction to the users. Load balancing is a relatively new technique that provides high resource utilization and better response time. Sometimes our system gets hanged up or it seems to take few decades for pages to come out of printer. All this happens because there is a queue of requests waiting for their turn to access resources which are shared among them. But these requests cannot be serviced as the resources required by each of these requests are held by another process or request by virtual machines. One cause for all these problems is called deadlock. Load balancing is a new approach that assists networks and resources by providing a high throughput and least response time.

job so that all customers can benefit from it. A trivial example would be using a proportional cost sharing scheme, Minimization with a concave cost function usually falls into the class of NP-hard problems This partially suggests the hardness of our scheduling problem. Though we have not formally proved its NP-harness, we have discovered the properties of optimal scheduling with a general concave cost function. Furthermore, these properties have inspired us to find an optimal offline scheduling algorithm for a special concave cost function. In this section, we present the properties that an optimal schedule should have and point out why it is hard to come up with an optimal scheduling algorithm with polynomial complexity. They used Offline algorithm , That is based on the priority-based scheduling, it has been considered by history and time. First who approaches may get first preference.

Efficient VM Load Balancing Algorithm for Dynamic Allocation of Resources in Cloud Computing Environment

Efficient VM Load Balancing Algorithm for Dynamic Allocation of Resources in Cloud Computing Environment

Our algorithm estimates the resources assignment depending on the VM requirements. Here we describe the server a hotspot and if the usage exceeds the above the hot threshold then it shows that the server is overloaded and VM' s are moved away. The temperature is zero when the server is not a hot spot. We describe a cold spot when the resource usage are below the clod threshold which shows that the server is idle and it has to be turned off for saving energy. This is performed when mostly all servers are actively utilized below the green computing threshold else it is made inactive. A. Hot Spot Mitigation: In sorted lists of hot spots are arranged in chronological order so that we can remove else to manage low temperature. Our objective is to leave a VM that can decrease the temperature servers. Among all, we select the one that can decrease skewness.
