Compare Client-Server architectural style to 3-Tier architectural style. What are the similarities and differences ? Use bullet points or a short paragraph.
Client-Server architectural style to 3-Tier architectural style:
The client-server model refers to the Network Architecture where one or more computers are connected a server.Client-server architecture divides the system into two applications, In this model client sends request to the server. Server implementation is transparent but can be centralized or distributed, single-threaded or multi-threaded single interface point with physically distributed implementation Dynamic, transparent selection from among multiple interface points. The purpose of networks is to allow communication

The BL is running on a separate server, called the business logic tier, middle tier, or service tier. Finally the DB is running on its own database server. Differences: Client-Server: cost (servers and software can be expensive) server operating systems (a server and software work together; server software is expensive; servers also add to the costs) implementation (sharing resources; network cabling; servers kept in a secure room; central file management, central security administration; user management and permissions, backup management) security and safety techniques to protect the network from virus attacks, new products, and the use of new technologies (i.e., wireless connections).
Client-server networks work best for larger setups, such as a full-scale office or school network -- especially if the networks are likely to grow in size.
3-Tier Architecture: A 3-Tier usually puts something between the presentation and data store tire such as a business logic tier.
3-Tier has a Middle part of stage to communicate with client to server, Where as in 2-Tier client directly get communication to server. you can put this into 3 tiers depending on how much amount of money you have for hardware and how amount load you expect.
3-Tier is straight means in that demand stream on Client Middle Layer Database server and Response.
3-Tier is similar to a MVC But having contrast sorts in topologies.

In a client and server caches, an each server cache is managed in one distributed system tier by a number of server members, usually cache server processes. In a separate tier, clients maintain their own caches that automatically call upon the server side to set off cache to update the server with client updates. In addition, the clients can member to server events using both data key specifications and queries. The client/server topology can be extended to any number of tiers.
To reduce the risk of these types of attacks, routers should be hardened, packet filtering controls should be used and routing information should be controlled.
at a time,they are commonly connected to a LAN and run multiuser operating system.The resources which has to be managed
Layer 4 which is the Transport layer responsible for end to end connection. It parts and collect the data and is made into data streams. It ensures that the data is established and maintained. It also detects any errors found in the data while transferring as well as recovering those
Web applications use a three-tiered architecture: The first tier is the Client Browser application, the second tier is a Web Server, and the third tier is a ________ .
There are multiple aspects of security in this network, which I have tried to implement as much as possible. This is where the CIA triangle comes into play, confidentiality, rules and limits to access information; Integrity, making sure the data is accurate and trustworthy; Availability, having reliable access to the information. I am going to talk about each aspect in a list format and explain how it’s used in my network. One thing that will be performed on all network devices is system updates and patches. They will happen on a monthly basis, on a weekend when the networks are not being used.
A client/server architecture is an end-to-end systems that contains server hosts (contains the resources and services needed by the client) and clients (users or workstations in the network). “Most client/server networks have more than one client to a server so that the system shares computing power. There are a few different kinds of servers to include file sharing, printer services, email services, database services, web services, and a server can used for it power. Clients can access all of these different servers at one time and the servers can serve many clients.” (Techopedia, 2014) For large businesses with office throughout the country web based computing or cloud computing shows the greatest benefit. In web-based computing it is not the local computer doing all the work but rather computers off site that do the work. The user’s computer runs off of a cloud computing system’s interface software which uses the offsite network computers to do the work.
Queueing models will be set up comparing the service time results when 4 servers are actively in use as opposed to the service time when only 2 of the servers are being used.
I have chosen the three-tier design, the user interface runs on the client and the data is stored on the server. A three-tier design also has a middle layer between the client and server that processes the client requests and translates them into data access commands (Shelly-Rosenblatt, 2012).
Servers and Network configuration implemented as a solution to the Over the Counter Benefit that the plans offer to their members. The ordering processes are very similar in the different components since there is a common API based core providing the same services for all of them.
The one tier is best suited for single users that have a small amount of information to store. It will run on the machine the user is using and will store it on the machines (computer, tablet, cellphone, ect) and has to use a physical resource to access and process this information.
for the logical design model, segments an application's components into three tiers of services. It
Two main differences in architecture were identified during the prototypes development: the level of coupling between the frameworks’ components and the first targeted components in the request lifecycle.
many different variations of architecture tier an application may have such as an UI tier, caching tier, application tier, and persistence tier such as SQL or table logging.
In a traditional three-tier architecture is a client-server architecture in a company data center which consists of presentation tier, business logic tier and data tier. Each tier is developed and maintained as an independent tier.
