A load balancer diagram shows a network of application servers. Each server is assigned a particular weight or amount of power. Client requests for applications go to the most powerful application server. Two of your application servers might be two times more powerful than the third. Each client will request the exact same amount of data from each server, but their requests will be routed differently to the servers.
Hashing algorithm
Diagram of a Load Balancer shows how requests are routed from healthy servers to those with IP addresses. Load Balancing uses the Hashing algorithm. The Hashing algorithm generates an unique requestId that uniquely identifies every client request. The hashing results are used to send the request to the appropriate server.
Distributed systems need to hash requests in order to make them evenly distributed among servers. Keeping hashing consistent across nodes minimizes the amount of work that needs to be done by the cluster every time a ring changes.
Connection multiplexing
Connection multiplexing can be used to distribute traffic between multiple servers. The load balancer chooses the right service when a client requests it. An ADC must track both the initial connection as well as any follow-on traffic initiated by the client to accomplish this task. This is an important task, because follow-on traffic may have two specific problems: connection maintenance and persistence.
Connectivity multiplexing in load balancer diagrams can be done simply by dividing total connections by number of servers. Each server is assigned an IP address and port. The loadbalancer will accept a request from a client for a particular service and rewrite packets to include the destination address of the virtual server.
SSL Passthrough
SSL passthrough is a great way to configure SSL in a loadbalancer. It places all encryption and decryption work on the load balancer, so certificate management is easier. SSL passthrough protects traffic between the loadbalancer and backend servers. However, it could expose customer data and other network instances. It is not recommended for networks with lower security.
SSL passthrough is more expensive and requires more CPU cycles. This method is not suitable to high traffic deployments. It does not support access rules, sticky sessions, and redirects. It is therefore only suitable for small-scale deployments.
Network server load balancer
A load balancing device is a network device that redirects packets so they reach their destination. A loadbalancer can handle different types and traffic depending on their source IP. The process of load balancing involves multiple servers. The first server acts as the "front-end", and receives traffic. It then forwards it to another server. A second server serves as a back-end and responds to clients' requests.
The load balancer can be a hardware appliance or a software-based virtual device. If one server goes down, the load balancing will redirect the user's requests to the appropriate servers. It will also automatically transfer requests if another server has been added.
Kubernetes load balancer
A Kubernetes load balancer diagram shows how one pod handles requests and the other pod handles responses. One of the key problems with this approach is that it does not account for persistent connections. This means that load balancing should be implemented on the client side by the application. This issue can be solved with kube-proxy or iptables. These solutions do not account for specific applications and are meant to cover the most common deployment scenarios.
Kubernetes allows each pod to have its own IP addresses. The above diagram shows that each red pod sends requests to a service having a fixed address. The controller will then collect the pending Service requests and assign them unique IP addresses so that they can deliver the incoming packets.

What is responsive web design?
Responsive web design (RWD), is a way to create websites that display responsively on all devices, including smartphones, tablets, desktop computers, laptops and tablets. This allows users to simultaneously view a website from one device while still being able to access other features, such as navigation menus and buttons. RWD is intended to ensure that any user viewing a site views the exact version on their screen.
A website that sells primarily through eCommerce would be an example of this. You want your customers to be able to purchase products from your store, even if they are viewing it on a phone.
A responsive site will adapt to the device used to view it. The site will display exactly the same way on a laptop as if it were viewed on a desktop computer. But, the page will appear differently if you view it on your phone.
This allows you to create one website that works on all devices.
WordPress: Is it a CMS or not?
The answer is yes. It is a Content Management System (CMS). CMS allows you control your website content using a web browser and not an application like Dreamweaver, Frontpage or Frontpage.
WordPress is absolutely free! Hosting, which is usually provided by your ISP, is free.
WordPress was originally created to be a blogging platform. But WordPress now offers many more options, such as eCommerce sites or forums, membership websites and portfolios.
WordPress is very easy to set up and install. To install WordPress, you will need to download the installer file from their website. Once it is downloaded, upload it to your server. Next, simply go to your domain name via your web browser and log into your new site.
After installing WordPress you will need to create a username/password. Once you have logged in, a dashboard will appear where you can view all of your settings.
From this page, you can add images, pages, posts, menus or widgets to your website. This step can be skipped if editing and creating content is easy for you.
You can, however, hire a professional Web designer to handle the whole thing if your preference is to work with another person.
