A load balancer diagram shows a network of application servers. Each server is provisioned according to its weight or power. A client request for an application goes to the application server that is most powerful. 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
A Loadbalancing diagram shows how requests are routed via IP addresses to the right servers. Load Balancing employs the Hashing algorithm. The Hashing algorithm creates a requestId which uniquely identifies each client's request. The result of the hashing is then used to direct the request to the desired server.
In distributed systems, hashing is important to map requests evenly between the servers in a cluster. 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 allows traffic to be distributed to multiple servers using one of many common methods. The load balancer determines which service is available when a client sends a request. 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 can have two problems: persistence and connection maintenance.
Connectivity multiplexing in load balancer diagrams can be done simply by dividing total connections by number of servers. Each server has its own IP address and port. When a client requests a particular service, the load balancer will receive the request and rewrite the packet to include the destination IP address of the virtual server.
SSL passthrough
SSL passthrough can be used to configure SSL in a loadbalder. This method places all encryption/decryption work on a load balancer, making certificate management easier. SSL passthrough makes sure that traffic between load balancers and backend servers is secure. But, customers' data can be exposed to other network instances. It is best for networks with less security.
SSL passthrough requires more CPU cycles and operational costs. This method is unsuitable for high-traffic deployments. This method also doesn't support creating access rules, sticky session, or redirects. As a result, it's only appropriate for small-scale deployments.
Network server load balancer
A load balancing is a network device, which rewrites packets until they reach their destination. A load balancer can handle different kinds of traffic, depending on their source IP address. The process of load balancing involves multiple servers. The first server is a "front end" that receives traffic from clients and forwards it on to the next server. A second server acts in the "back-end" role and replies to clients.
Load balancers can be either hardware appliances or software-based virtual devices. If a server is unavailable, the load balancer will redirect requests to other servers. If another server is created, it will automatically transfer requests.
Kubernetes load balancer
Diagram of Kubernetes loadbalancing shows how each pod handles requests and the other 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. Luckily, there are a number of solutions for this issue, including kube-proxy and iptables. These solutions can only be used for common deployment scenarios. They do not address the specific requirements of particular applications.
Kubernetes gives each Pod its own IP address. Each red Pod sends requests with its own IP address to the service in the above diagram. The controller will then collect the pending Service requests and assign them unique IP addresses so that they can deliver the incoming packets.
FAQ
What is a static website?
A static site can be hosted anywhere. This includes Amazon S3, Google Cloud Storage. Windows Azure Blob storage. Rackspace Cloudfiles. Dreamhost. Media Temple. You can also deploy a static website to any platform that supports PHP such as WordPress, Drupal Joomla! Magento PrestaShop and others.
Static websites are typically easier to maintain, as they don’t have to constantly send requests between servers. They load quicker because they don't need to send requests back and forth between servers. These are just a few reasons why static web pages can be a better option for small companies who don't have the resources or time to maintain a website.
