Question

Operations and maturity phases of Hosted Client-Server Model: In the operations and maturity phases of your implementation plan, discuss best practices for how you will assess if the system is functioning at an optimal level including response times and down-time procedures .

Discuss one evaluation method that can be used to determine if changes need to be made in the future. Consider at least one financial approach including a cost-benefit analysis, cost-effectiveness analysis, or break-even analysis in your response

Explanation / Answer

The cloud computing maturity model or CMMM refers to a model designed for managing cloud services; the model is meant to help business executives to make progress while offering cloud hosting services to client enterprises. So the CMMM basically benchmarks services and evaluates the level of success or achievement of service targets. So the CMMM basically seeks to explain the actual means by which cloud services are delivered, showing controls and events that can help in the automation of such services.

The CMMM goes through multiple stages where the initial stages are devoted to getting these cloud services off the ground. The following stages focus on providing better practices for managing such services or more automation. This explains why many experts state that this cloud computing maturity model is really a unified approach towards IT-as-a-Service. In this, most of the company’s operations are offered across the Internet instead of being maintained in-house.

The CMMM is really a maturity grid meant for cloud vendors. Like other maturity models, it represents a grid or matrix that is presented through columns and rows. The criteria which will be evaluated will be placed in the left column while the corresponding row will include the typical behavior in each development stage. The model should ideally not have greater than 5 levels. The fifth level is the most professional level. Once this model is made, it gives the vendor a good insight into how close it has come to being fully developed in terms of specific criteria. For example, this model can help to show a vendor that while it has the power to balance load during traffic spikes, it needs to improve the interface.

example:-

When a bank customer accesses online banking services with a web browser (the client), the client initiates a request to the bank's web server. The customer's login credentials may be stored in a database, and the web server accesses the database server as a client. An application server interprets the returned data by applying the bank's business logic, and provides the output to the web server. Finally, the web server returns the result to the client web browser for display.

In each step of this sequence of client–server message exchanges, a computer processes a request and returns data. This is the request-response messaging pattern. When all the requests are met, the sequence is complete and the web browser presents the data to the customer.

This example illustrates a design pattern applicable to the client–server model: separation of concerns.
