  1. What is Elastic Load Balancing (ELB) in AWS? And The Types of AWS Elastic LoadBalancers What is Elastic Load Balancing (ELB) inAWS? Elastic Load Balancing is shortly called as ELB that allows the income of traffic to get easily distributed across the plenty of healthy EC2 instances, IP Address, and containers in an automatic way. It is considered as the single point to make contact with the client and helps to increase the availability of applications which allows adding or else removal of different EC2 instances across single or else more availability zones. It mostly achieves the fault tolerance for any of the applications which mainly ensures performance, scalability, andsecurity. The AWS ELB helps the team of IT in order to adjust the capacity with respect to the network traffic and the incoming application. Now the users can enable the ELB with just a single availability across the multiple or varied zones that helps to prepare the best application according to theperformance. Basically, the load balancing concept in AWS can be categorized according to the amount of work where the computer has to perform the multiple actions. With the help of these, the users can get served faster. The following are some of the increased features of Elastic LoadBalancing.

  2. Easily detects all the unhealthy cloudinstances • It can help to spread the healthychannels • Great cipher support • Best and centralized managed along with the SSLcertificates • Avail the publicauthentication • This AWS ELB will support the both IPV4 andIPV6 High availability: Availability is one of the best and well-known services in ELB by the AWS, as it performs the best health check in order to ensure instance while sending the traffic. If the instance fails, then the traffic routes at ELB will remain healthy for EC2 instances. As the EC2 instances availability zone is completely unhealthy then the availability traffic zones can route them until when they get the healthystate.

  3. Automatic scalingProcess: Any developer can be eligible to use this AWS auto-scaling aspect in order to get enough more EC2 instances there by running an ELB. The developers can use all the auto scaling conditions when needed. If the condition written by you will meet the requirements then a new EC2 instance can automatically desire your required needs easily. Security: However, ELB basically helps to supports the applications which are currently available in the Amazon Virtual Private Cloud in order to maintain the strong security of the network. If the IT team wants a specific internet facing, it can easily display the route traffic according to the IP addresses. This type of approach will help the IT team to allow the best security group not only for the targeted traffic but also for the private IP addresses that are specified to expose the reliable application by using the multiple internetfacing. What are the types of AWS Elastic Load Balancers? Eventually, the ELB at AWS offers the two different load balancer features that help to offers the best and scalable cloud computing easily. However, the application load balancer can easily handle all the advanced routing traffic by using the remaining containers and services, whereas the other load balancers like Classic and Network will automatically spread the traffic across the EC2instances. Based on the features like high availability, robust security and automatic scaling to make the applications with fault tolerance, Elastic Load Balancing in AWS is divided into three types that are Application LoadBalancer Network Load Balancer Classic LoadBalancer

  4. 1. Application LoadBalancer • Application Load Balancer is the main thing in ELB which is best suited for load balancing in HTTP and HTTPS traffic. It has also come up to provide advanced requests routing targeted with effective delivery of modern applications architectures which includes certain containers and microservices. Application Load Balancer routes traffic gets targeted to Amazon Virtual Private Cloud (Amazon VPC) based on the request. The improves the security of the applications and simplifies with ease to ensure the trending SSL and TLSciphers. • KeyFeatures • HTTPSSupport • Server Name Indication • IP Address asTarget • SecurityFeatures • High Availability • Content-Based Routing • Web Socketssupport • Native IPv6 support • StickySessions • Logging • DeleteProtection • RequestTracing • Web ApplicationFirewall 2. Network LoadBalancer Network Load Balancer in AWS technology is best suited for load balancing of various TCP traffic with high requirement of extreme performance. The operating level at the connection level is probably Layer 4 and the Network Load Balancer routes traffic which can easily get targeted with Amazon Virtual Private Cloud. Keeping in Ultra-low latencies, it can handle millions of request for every second in an efficient manner. It can also handle volatile and sudden traffic patterns that help organizational revenues. Everything is handled by using single static IP addresses for each availability zone. It can also integrate with other AWS serviceslike Amazon EC2 Container Service (ECS), Auto Scaling and Amazon CloudFormation.

  5. KeyFeatures • Connection Based LoadBalancing • High Availability • High Throughput • LowLatency • Static IPSupport • HealthChecks • DNS FailOver • Central APISupport • Enhanced Logging 3. Classic LoadBalancer Classic Load Balancer has come up to deliver basic load balancing across various multiple Amazon EC2 instances. It can also be operated at various levels such as connection level and request level. Classic Load Balancer is mostly built for the applications that are within EC2 classic networks. When usage of Virtual Private Cloud(VPC), Application Load Balancer is for Layer 7 and Network Load Balancer is for Layer 4. • Key Features • High Availability • Health Checks • SecurityFeatures • SSLOffLoading • StickySessions • IPv6 support • Layer 4 and Layer 7 Load Balancing • Operational Monitoring • Logging Related Page: AWS InstancePricing

  6. What is the use of load balancer inAWS? • Load Balancers in AWS Technology are mostly used to enhance capacity and reliability of the applications. It also balances the traffic across the target levels in an automatic way. The below are the real-time use cases that are used by Load Balancer in AWS Technology. • Achieves Fault Tolerance for Applications in BetterWay • Load Balancing For containerized Applications in an automaticway • Scales up the Applications in an AutomaticWay • Elastic Load Balancing in Amazon VPC • Hybrid Load Balancing with Elastic LoadBalancing • What is AWS ELBLogs? • AWS Elastic Load Balancing has come up with the main aim to build systems in highly scalable and reliable manner. It can easily distribute the traffic across Amazon EC2 instances in dynamically sized collections in an efficient manner. It can easily help in creating two or else more EC2 instances in an efficient manner. Each individual instance is helped to resolve an access request point in the right way. All the access requests are simply routed to EC2 instance under the least load in real time scenarios. The Elastic Load Balancing Logs are produced for the usageof • Analyzing the access and traffic patterns • Troubleshooting of variousapplications • Performing of high-securitymonitoring • Improvement in the userexperience • Discovering and debug problems with the EC2platform

  7. AWS ELB HealthCheck In this AWS ELB Health check, the property called as HealthCheck configures the health checks for the availability of various EC2 instances. The load balancer routes are completely requested to the various healthy instances. Probably, the load balancer is here to determine the respective instance which is unhealthy and stops the requests for the particular routing purpose. The routing process starts only after the particular instance comes to healthystates. Then AWS ELC checks whether the instance is in a healthy state or not and then it starts requests for particular routingpurpose. AWS ELB Pricing andCost The pricing and cost are highly varied for the various types of Elastic Load Balancer where you can pay with ease. The pricing also sometimes varies from region to region as well. Application Load Balancer: In this, one can be charged for each hour or else partial hour where an Application Load Balancer is running along with the number of Load Balancer Capacity Units shortly called as LCU are used perhour. Network Load Balancer: In this Network Load Balancer, one can be charged for each hour or else partial hour which can be easily run through Load Balancer capacity Units that are used perhour. Classic Load Balancer: When this Classic Load Balancer is running, it is normally charged per hour or else partially hour and also for each GB of the data which is transferred from the Load Balancer.
