Application Of Distributed Application Challenges

Instead, multiple isolated subsystems, called containers, run on a single control host and access a single kernel. As shown in Figure 4, containers share the same OS kernel as the host; containers are usually more efficient than VMs, each of which requires a separate OS instance.

4. Applications where various of machines can be doled out for each to do a task e.g every processing a single file

Please compare component based integration (synchronous) and message based integration (asynchronous). Describe their advantages and disadvantages. [15 points]

Cloud computing allows organizations to utilize virtual recourses; like virtual machines, storage, and applications. Rather than building and maintaining

By treating process as isolated virtual machines modern computers can run them concurrently while maintaining the stability, and data integrity. As the tech support for my family this has an enormous impact since the overall stability of these devices are vastly improved, and although complexity has increased, problems are better isolated and easier to fix. Consequently I spend less time fixing software problems.

To overcome the above issues, use a hybrid cloud infrastructure [2]. It combines public cloud, private cloud and dedicated servers (Figure 1), which works in one platform. It satisfies the purpose of different businesses.

Although each product group has its own particular needs and programing requirements, the divisions of each group should be working with the same programming and technology system.

These virtual machines have a separate operating system, memory, processor and other resources which is the shared by the resources of the

Not all cloud computing systems have the same user interface. Most of the time, servers don't run at full capacity. That means there's unused processing power going to waste. It's possible to fool a physical server into thinking it's actually multiple servers, each running with its own independent operating system. The technique is called server virtualization. By maximizing the output of individual servers, server virtualization reduces the need for more physical machines.On the back end of the system are the various computers, servers and data storage systems that create the "cloud" of computing services. In theory, a cloud computing system could include practically any computer program you can

(4) Platform as a Service - This offers a development environment as a service. You can use this technology to develop your own applications that run on the providers server.

If you have multiply users and a small scale of applications you would use the two tier client/server architecture. This would be an example of anyone that uses the

Today intensive research is being put into the field of containers. Huge corporations like Google and Twitter are today investing heavily in developing container technology. The Docker project and Google’s Kubernetes project are two open source projects which have caught huge traction recently. We shall be using these softwares for supporting different modules of our project.

Application Runtime: This is where a developer uploads his code and does not have to think about the underlying architecture, servers needed to provide different components, they handle them in a very scalable and highly maintainable multi tenant way that is from an operations point of view a developer has to adjust some knobs only to manage or scale his application, to increase or decrease web processes or manage background processes or need of another database or scale the current database, all these things a click away from the developer rather than any configuration or

According to Andrew Tanenbaum “A distributed system is a collection of computers that appear to its users as a single coherent system.” (http://www.cs.helsinki.fi/u/alanko/hj/K06/kalvokopiot/ch1_p6.pdf) Almost every current company uses distributed systems connected to servers and even larger databases. Each of these companies connects their organization and its information through local area networks also connected through server farms managed by administrators. Server side operating systems provide the server or database administrator to manage use on different computers that share information.

Linux-based containers are emerging cloud technologies based on fast and lightweight process virtualization. It offers users an environment near identical performance to a standard Linux distribution, as opposed to para-virtualization solutions (Xen) and other hardware virtualization solutions such as KVM. It is not necessary for a Linux- container to create a new operating system kernel for each new instance. Because containers are lighter weight than VMs, it
