Designing A Application Using And.net And The Authentication Api

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

One server can run multiple Software and deliver high application availability. Software virtualization supports business continuity and disaster recovery. Server and storage virtualization have both been used for years, though virtualizing servers is the more popular trend. (Toigo, 2011).

Shared Resources amongst Different Platforms: Applications used for client/server model is built regardless of the

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.

There are lots of issues that user has to face when user uses more than one cloud providers’ infrastructure for one application. The main issues are listed below:

The challenges for OS structures depend on the diversity of hardware like number of cores, memory hierarchy, IO configuration, instruction sets and interconnects.

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

There will be a variety of servers employed. For example, applications will be run on one

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

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

- Make sure the applications are tested for stability and compatibility before moving them to cloud.

At the beginning of the application architecture world, we had mainframes that executed all the applications logic in a centralized manner and the mini computers as terminals that just displayed the applications screens to the users and captured user’s inputs. The main advantage of this architecture was that deployment was easy to perform. The main disadvantage was that user interface was very limited, the display was characters based and the user’s inputs was limited to a keyboard.

When properly implemented, container technology, distributed computing, and microservices architectures promise improved scalability and resiliency over monolithic applications. Yet, it’s difficult to expose dynamic services built using these technologies to the outside world. Securely exposing dynamic applications is difficult because their location is always changing due to activities such as being updated or scaling up or down. Understanding where applications reside, controlling access to them, and isolating them
